[RESOLVED] HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed

Hi,

The relevant project has been deployed fine in the server but when it is being called by one other project, I got this. Why?

Server Error in '/App11' Application.

--------------------------------------------------------------------------------

The resource cannot be found.

Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly.

Requested URL: /App11/Detail.aspx

--------------------------------------------------------------------------------

Version Information: Microsoft .NET Framework Version:4.0.30319; ASP.NET Version:4.0.30319.18044

I would suspect that you are calling a relative URL, but the web address is different on your deployment server. In other words, you were using the same web address in development, but they have different addresses in production.

No, it is being called like this

Response.Redirect("http://192.168.168.1:81/App11/Detail.aspx");

and I see in IIS, App11 has been deployed properly.

Verify your ports then. Make sure that they are not blocked by any firewall (server and client).

But other projects deployed in the same way, are working fine there.

Look at the "path" from the requesting page to this page that is apparently invisible to the requesting page. What is different between this "path" in comparison to your other projects/pages. This would involve any kind of network interaction, especially
firewalls, between the requesting page and the requested page.

Sorry, I don't see any difference within security of the path of the current project in comparison with other projects.

Hi,

Try setting up a Reverse Proxy using IIS, URL Rewrite and ARR

There are a lot of specific points where this could go wrong. For starters the bindings; if you're using different hostname bindings then that could obviously cause a problem. Have you tried using this same URL from your location to see what happens?

Also important to know; is there anything specific mentioned in the IIS logfiles? Because that could give you a good clue as to a possible cause.

[RESOLVED] Bind Image From Physical path outside web directory to Datalist

Hi ,

I am trying to bind a image which is located outside web directory so clients do not have access to resource file to asp Image in datalist control but images are not displayed as it is located other drive phiscal location and it is manadatory for me to
do so please suggest me a solution on this

please find the aspx page below

If you check out the
Image class then the main property to look out for would be
ImageURL. This property can use both relative as well as absolute paths.

I'm not sure because I never tried this myself; but I would imagine that you should be able to point an absolute path to the image you're trying to use.

Create virtual directory in iis to the phiscal location, then use this virtual directory to display the image seems like the files is in your application.

Hi,

Or you could use : http://www.dotnetperls.com/ashx . This way you'll use a link such as
/image.ashx?id=name. The handler will get the image form whatever location you want and will sent it back to the browser.

[RESOLVED] Linkbutton string not working when there is & in the company name

in my asp.net+vb web i am using one linkbutton. by this i used to browse the details of company

PostBackUrl="unitlink.aspx?unit=TATA Motors">Tata Motors

PostBackUrl="unitlink.aspx?unit=L&T">L&T

The first linkbutton woks fine and when i click on thhe second one iit doesn't work i checked a lot it is because there is & inthat company name how can be it solved

You should use UrlEncode and UrlDecode

Those methods should be used any time you're inserting user inputted data into the query string.

Hi,

Try adding this to your web.config if you are using .NET 4.0:

system.web>
            requestValidationMode="2.0"
        requestPathInvalidCharacters="<,>,*,%,:,&,\"
        relaxedUrlToFileSystemMapping="true"
    />
    ...



    
        
    
    ...

[RESOLVED] configuration file

Hi expert, do I need a configuration file in order for a vb.net page set up in a virutal directory to run in IIS7?

I read some articles, and some said we don't have to.

So what is the standard configuration file for IIS7? Your advice is greatly appreciated.

Thank you!

Hi,

Here is a quite detail

[RESOLVED] How do I get SqlDataSource Control parameters from a FormView Drop Down

I have a drop down in a form

                                DataSourceID="SqlLimiter" DataTextField="ShortName" DataValueField="myID">

I want to get to the selected value as a "control parameter for my SQLDataSource Query.

            SelectCommand="SELECT [myID], [ParentType], [ShortName], [IsActive] FROM [Categories] WHERE (([ParentType] = @ParentType) AND ([IsActive] = @IsActive) AND ([ParentID] = @ParentID) AND ([StoreID] = @StoreID))">

It won't work because it is "contained" within the formview container edit mode

How do I get around this?

I tried following this.

http://geekswithblogs.net/AzamSharp/archive/2006/08/27/89475.aspx

But it didn't work.

        SelectCommand="SELECT [myID], [ParentType], [ShortName], [IsActive] FROM [Categories] WHERE (([ParentType] = @ParentType) AND ([IsActive] = @IsActive) AND ([ParentID] = @ParentID) AND ([StoreID] = @StoreID))">

Simply bind it, SelectedValue = '<%# Bind("ParentId") %>' then in parameter use

Simply bind it, SelectedValue = '<%# Bind("ParentId") %>' then in parameter use

Hello,

I also have a problem of parameter not going through, but I guess the reason is different.

The two controls and their datasources are together, on the development machine it runs quite OK, but on an IIS server it seems the parameter stays empty. Is the syntax different ?

I tried what you say, but I am afraid I did not manage the quotes properly, which gave an error on the page.

The blog was the answer to my problem and referencing the container as parent to the child element.
FormView2$DepartmentSelected

It wasn't working for some reason right away because of some other minor issue.

It doesn't matter if its in the same piece of code, you can't get to the parameter if it is a "child" or a "contained" object, ie, with gridview, formview without referencing that. Shouldn't be any different between IIS and development
but practically its Microsoft code so everytime you compile it on a different machine you get different results. So very common to see a piece of code tested working at one place not to work at all on another place.

Maybe you need code behind

Protected Sub DepartmentSelected_SelectedIndexChanged(ByVal sender As Object,
ByVal e As System.EventArgs) Handles DepartmentSelected.SelectedIndexChanged
   SqlCatLimiter.SelectParameters("ParentId").DefaultValue = CType(sender, DropDownList).SelectedValue
End Sub

    Protected Sub SqlCatLimiter_Selecting(ByVal sender As Object, ByVal e As
    System.Web.UI.WebControls.SqlDataSourceSelectingEventArgs) Handles SqlCatLimiter.Selecting
        Dim ddl As DropDownList = CType(FormView1.FindControl("DepartmentSelected"), DropDownList)
        If ddl IsNot Nothing Then
            SqlCatLimiter.SelectParameters("ParentId").DefaultValue = ddl.SelectedValue
        End If
    End Sub

oned_gk

SqlCatLimiter.SelectParameters("ParentId").DefaultValue = CType(sender, DropDownList).SelectedValue

You know, I am afraid the DefaultValue is ignored. In fact I put one at design time to show the subcategories of the first category, but the subcategory dropdownlist stays empty. I tried to modify it as you say at the selection of a value in the category
dropdownlist, but that changed nothing.

As soon as I remove the system.data section in the Web.config, it runs jolly good on the development machine, but the server throws an exception on the page, as it does not find the provider for the database. They did not install the MySql Connector Net,
and do not seem willing to do it.

One of the big differences between the development system and propagation to IIS will be the "data". I bet the database and data are different. The development system probably had a hefty data set and now on IIS there is no data. This will create bugs
and problems you didn't see before. One of those would be default values and "null" situations.

Hello,

I found the answer the day after while reading an example in the MySqlMembershipProvider code from CodeProject.

It is very simple :

with SQL Server, in a SQL request code you mark a parameter with the @ character
with MySql, in a SQL request code you mark a parameter with the ? character.

And that is it.

My page is now online, and the parameters are very well transmitted from a dropdownlist to the other.

[RESOLVED] Display image as per query string

In my asp.net+vb web with access database there is a page which displays data as per query string and the string is PNO and all data is correctly displayed in gridview and dataview. there is a Image1.ImageUrl and
i used the following code but it is not working

Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim PNO As String
        PNO = Request.QueryString("PNO")
        Image1.ImageUrl = "C:/wing/Photos/" + PNO + ".jpg"
    End Sub

When displaying image in web page, use virtual path instead local path like Image1.ImageUrl = "~/wing/Photos/" + PNO + ".jpg". The wing folder can be physical folder or virtual directory under your application (iis virtual directory).

u cannot use local path of image... it must be a virtual path to the web directory.... for example, if "wing" is a name of the folder where u r application is present then, u can do this

Image1.ImageUrl = Server.MapPath("Photoes") + "/" + PNO + ".jpg"

hope this helps...

in a search page of my web the following code is working fine

Dim PNO1 As String = "11022"
        PNO1 = " + inputtxt.Text + "
        Image1.ImageUrl = "~/Photos/" + PNO + ".jpg"
        'Image1.ImageUrl = "C:/Awing/Photos/" + PNO + ".jpg"
        'Image1.ImageUrl = "\\ms16eme/Awing/Photos/" + PNO + ".jpg"
    End Sub

but when it goes to a string with a hyperlink from another page

 Protected Sub Page_Load(ByVal sender As Object, ByVal e As EventArgs)
        Dim PNO As String
        PNO = Request.QueryString("PNO")
       Image1.ImageUrl = Server.MapPath("Photos") + "/" + PNO + ".jpg"
        End Sub

this is not displaying the image

please suggest a solution

1. Local physical path is used to save your file to server harddisk

example : c:\myweb\myfile.jpg, d:\user\me\project\myweb\file.txt

2. URL is deferent with physical path, its used in your browser

example : http:/domain/myimages/file.jpg

in asp.net control you can use : ~/myimages.jpg

3. ImageUrl, use No 2 sample

4. Server.Mappath is used to determine local physical path when you want to save the file,

dont sever.mappath to set ImageUrl

i tried various codes but not able to process

The main problem is the input is a string (eg kc1432) and the imake name is KC1432.jpg all data from tables displays from database but image from folder is not displayed

Dim PNO As String

PNO = Request.QueryString("PNO")

Image1.ImageUrl = "~/images/" + PNO + ".jpg"

end sub

Place "Images" folder under your application, if you want place it to another location after published. Creare virtual directory "images" under the application.

the photos are placed inside the images folder in my web directory still it is not working

i got a code from a forum as under but i am not able to edit as per my requirement as i use query string
PNO and the file name varies as per the pNO changes

[RESOLVED] ListView not declared

Using VS 2010 and .net 4.0 framework. I am getting the error below when I open my code-behind page that contains a ListView control. Below the error is the code where it is occurring and the code in the editor shows underlines everywhere that the ListView or
events is referenced. How can I resolve or what else can I give to help resolve this? Thanks. 'lvJobSetupSelections' is not declared. It may be inaccessible due to its protection level. Protected Sub lvJobSetupSelections_ItemCanceling(ByVal sender As Object,
ByVal e As System.Web.UI.WebControls.ListViewCancelEventArgs) Handles lvJobSetupSelections.ItemCanceling lvJobSetupSelections.InsertItemPosition = InsertItemPosition.None End Sub

hi dlchase89 ,

From what I understand you come across the issue that 'lvJobSetupSelections' is not declared when you use
ListView Control.

It was becuase you had renamed a copy of the *.aspx file and which still using the newer versions code behind file. The code behind file was looking for “lvJobSetupSelections“ ,but on the older version of the *.aspx file “lvJobSetupSelections“ didn’t exist!

I would suggest you to exclude the older version of the page from the project and then it appears to run ok .

If you need more assistance ,please let me know.

Actually, I am geting this error on multiple pages, all with a ListView control. This is just a hunch but is it due to something in the web.config file? This website project was upgraded from 3.5 to 4.0 framework using VS 2010.

hi dlchase89,

if you don't want to delete older version page and re-create new .

i would suggest you to try the following link to alter web.config file:

http://forums.asp.net/t/1925542.aspx/

i hope it helps you.

I decided to publish my web.config file (except for secure items) to see if anyone finds something out of order since I am getting the error on every page that has a ListView. Note this website project was in .net 3.5 and we converted to .net 4.0

I think I isolated the problem. I started rebuilding the website from scratch and in the new web.config file it created the following entry inside the section. When
I imported web pages from the old site that have ListViews I did not get the error. However, when I try to run the website from IIS it throws an exception as shown below. I think I am closer but still need some expert guideance. How can I get IIS to work with
the targetFramework="4.0" setting? The website is running under an app pool for .net 4.0 Exception message: The value for the 'compilerVersion' attribute in the provider options must be 'v4.0' or later if you are compiling for version 4.0 or later of the .NET
Framework. To compile this Web application for version 3.5 or earlier of the .NET Framework, remove the 'targetFramework' attribute from the element of the Web.config file.

hi dlchase89,

From what I understand you want to import the xml data into the Excel file, and mapping it to Excel fields.

I would suggest you to try the follow setting:

Select your website in IIS => Basic Settings => Application Pool => Select
.NET Framework Version4.0.

Please read the reference below for more information:

http://stackoverflow.com/questions/15241627/configuration-error-compilation-debug-true-targetframework-4-0-asp-net-mv

If you need more assistance ,please let me know.

The App Pool is already at 4.0, thanks.

hi dlchase89,

From what i understand that your web.config is right but i don't kown that your last issue.

can you tell me your error message in oder to understand you issue better.

I was getting a "ListView is not declared" error on every page in the application that contained a ListView control. I solved it (for now, but not really sure why) by entering a section into the section of the web.config. I followed
an article about manually configuring your web.config for going from 3.5 to 4.0 and the article indicated removal of this section.

[RESOLVED] WriteXml function

Hello, when testing this function on my PC it's work ok, I wonder if do we need to give some special permission on the IIS before pass this code to production?

ds.TC_CONTRATOSOC.WriteXml("contrato.xml", XmlWriteMode.WriteSchema)

You need to make sure that whatever user this application is running under has write permission to the folder where "contrato.xml" is located. If you are using Windows authentication, then write permission should be given to the user that is logged in.

Did you set the write access for that folder?

Hi,

This is purely problem with the permissions. You need to give permission to the folder for user IUSER if application hosted in IIS.

Hi nravindran,

You just need to give full permission and it will fix your issue.

Hi,

Please refer the below links

You just need to assign read and write permissions to the image folder. it's file permission issue.

hello

you need to giv permission to user .for that you can refer below

Here are the steps to modify ownership and permissions of folders and files:
1. Right-click the file or folder, click Properties, and then click the Security tab.
2. Click Advanced, and then click the Owner tab.
3. Click Edit, and then do one of the following:
· To change the owner to a user or group that is not listed, click Other users and groups and, in Enter the object name to select (examples), type the name of the user or group, and then click OK.
· To change the owner to a user or group that is listed, in the Change owner to box, click the new owner.
4. If you want to take ownership of the contents of the folder, select the Replace owner on sub containers and objects check box.
5. Click OK, and then click Yes when you receive the following message:
You do not have permission to read the contents of directory folder name. Do you want to replace the directory permissions with permissions granting you Full Control?
All permissions will be replaced if you click Yes.

Note folder name is the name of the folder that you want to take ownership of.
6. Click OK, and then reapply the permissions and security settings that you want for the folder and its contents.
Additional considerations
· An administrator can take ownership of any file on the computer.
· Assigning ownership of a file or a folder might require you to elevate your permissions using User Access Control.

[RESOLVED] how to open a file outside website folder..server.mappath

i want to open a word document file(which is outside the website folder) on a button click ..

for example if it is on D drive and in a folder name
Files and filename is xys.docx

How can use server.mappath to open this xys.docx

Please help..

You can't use Server.MapPath to resolve paths that lie outside of the web site folder structure. You can use a generic handler (ashx file) to read the contents of the file and write them to the browser. Something like this:

public class MyFileHandler : IHttpHandler

{
  public void ProcessRequest(HttpContext context)
  {
    if (context.User.Identity.IsAuthenticated)
    {
      context.Response.Buffer = true;
      context.Response.Clear();
      context.Response.AddHeader("content-disposition", "attachment; filename=" + filename);
      context.Response.ContentType = "application/octet-stream";

      context.Response.WriteFile(@"D:\Files\xyz.doc");
    }
  }

  public bool IsReusable
  {
    get
    {
      return false;
    }
  }
}

thanks 4 ur reply but how to call this in click event in C#.net

If you're in iis, you can use virtual directory.

Server.MapPath("~/VirtualDirectory/xys.docx")

Response.Redirect("~/VirtualDirectory/xys.docx")

In visual studio, use physical folder in the application, after you publish it, then use virtual directory to outside the application folder.

In your click event add

Response.Redirect("~/MyFileHandler.ashx");

Hi Calvinx,

This error mostly belongs to permission error, for this error we have mutiple solutions as per situation

Put the impersonate=false in web.config file.
If you want to put the impersonate = true in that case you need to provide the read/write permission to impersonate user on "C:\Documents and Settings\server name\ASPNET" folder or through process monitor utility you can check which file don't have sufficient
permission.
If you have windows server 2008 then you will not found the ASPNET folder and still want impersonate=true then you need to change the configuration in IIS 7.5/7.0.

Go to IIS -> select your application pool -> Advanced Setting -> Process Model ->Identity=ApplicationPoolIdentity

Go to IIS -> select your application pool -> Advanced Setting -> Load User Profile = False

See here for more details.

Hi wmec,

i think you can use, Response.Redirect() method in your detault page, that can direct you to your resired location, for example,

// in default.aspx
void Page_Load()
{
  Response.Redirect("~/Start/yourPage.aspx");
}

Thanks,

Hi,

You can make the default page setting in IIS level.

there might be other ways to do thi. You can check this post http://forums.asp.net/t/1196778.aspx?Cannot+get+default+page+with+navigating+to+URL+

If your server is running IIS7, you should be able to set the start page for your site in your web.config file

hi ,

if you want to be redirected to the http://mycomp.com:81/Start , and keep the
http://mycomp.com you can either use the response.redirect in your aspx.c# page and ifyou want to keep the address as it is and still being redirected , you can use the server.transfer ( as long as you are still in the same
domain)

one more thing you can also use javascript as well to do it :

or even in the html :

I suspect your actual question is how do you get your website running on the default port. For your site to be accessable via
http://mycomp.com then it has to be running on port 80, if it isn't you can't access it via that url. However to answer your question, put this in your global.asax file

protected void Session_Start(object sender, EventArgs e)
        {
            int port = Request.Url.Port;
            if (port != 80)
            {
                string url = string.Format("{0}://{1}{2}", Request.Url.Scheme, Request.Url.Host, Request.Url.AbsolutePath);
                Response.Redirect(url, false);
                HttpContext.Current.ApplicationInstance.CompleteRequest();
            }
        }

Thanks all.

Ramesh,

Yes, I am using IIS 7.5.

Do you mean to put the above into Web.config file of the startup project? Then how does the server know this, when the user has selected this to go?

http://mycomp.com

If you put my above code way in your webconfig , The default document page is load whenever your application load first time.

did you deploy the webconfig file in server ? if yes , then the server was automatically load this page in first time by whenever run your application . and anywhere we can load the page at second , third etc time .

Thanks.

The startup project has one Web.config file inside. Are you talking about the other Web.config file in the server? Do you know the relevant place of that?

No, Am talking about same webconfig .

See this disscussions :

I don't think people have completely grasped your problem. Changing the default document is not going to help you. Implement my code in the global.asax file.

Edit: Didn't realise you want the re-direction to work the other way

protected void Session_Start(object sender, EventArgs e)
{
    int port = Request.Url.Port;
    if (port == 80)
    {
        string url = string.Format("{0}://{1}:81{2}", Request.Url.Scheme, Request.Url.Host, Request.Url.AbsolutePath);
        Response.Redirect(url, false);
        HttpContext.Current.ApplicationInstance.CompleteRequest();
    }
}

However my point still stands, I don't think this is going to answer your actual problem. If your site isn't running on port 80 then you can't kick any code off to influence what happens when someone directs to your site. Sites run on specific ports, not
on servers, and mycomp.com is simply shorthand for mycomp.com:80 and if your site is on mycomp.com:81 then accessing mycomp,.com isn't going to hit your code.

Many thanks Aidy.

Do you think I have to change the port from 81 to 80, and then after applying your codes in Global.asax, it should work?

If your site running on both ports, then yes it would work. Or else whatever *is* running on port 80 should have the code added to its global.asax

[RESOLVED] FormView/Gridview question

Hi there,

I have a form that consist of gridview which enable Select and Formview initially in Insert mode. When the user select a row clicking the Select on the gridview I change the Formview mode to Edit showing the correct record, most of the time it works like
a charm but sometimes when I click the Formview Update I get 500 Server Internal Error,

I built a test page with only Formview in Edit mode showing one of the records and I Update it constantly and it works great, no error at all.

Any idea why I get this 500 Internal server error ?

there can be lots of reason for this.To view actual error you need to change config file as explained by Aristos

First you need to enable and see detailed errors of your web messages because this is a general message with out giving information's on whats really happening for security reasons.

With the detailed error you can locate the real issue here.

Also if you can run the browser on the server you get detail on the error because server recognize that you are local and show to you, or if you can read the log of the server using the Event Viewer you also see the detailes of your error.

on iis6

Note: You can avoid the Debug=true, you only need to close the custom errors for while, and get the detailed error page.

Also can help how to enable the detailed error messages from iis.
