You receive error messages when you try to upload a file to an ASP.NET Web page by using the FileUpload control in IIS 5.1 (910436)

WORKAROUND

C# code example

protected void Application_Error(Object sender, EventArgs e)
{
	// Code that runs when an unhandled error occurs.
	// Determine whether the request originates from the file upload Web page (FileUpload.aspx).
	if (Request.Path.EndsWith("FileUpload.aspx "))
	{
		
		// Obtain the error details.
		HttpException httpEx = Server.GetLastError() as HttpException;

		// Verify the expected error.
		if (httpEx.GetHttpCode() == 500 && httpEx.ErrorCode == -2147467259)
		{
			Server.ClearError();
			
			// Redirect the user to the custom error page (ErrorPage.aspx).
			HttpContext.Current.Response.Redirect("ErrorPage.aspx");		
		}
	}
}

Microsoft Visual Basic code example

Sub Application_Error(ByVal sender As Object, ByVal e As EventArgs)
 	' Code that runs when an unhandled error occurs.
 	' Determine whether the request originates from the file upload Web page (FileUpload.aspx).
	If (Request.Path.EndsWith("FileUpload.aspx")) Then
        
		' Obtain the error details.

        	Dim checkException As HttpException = CType(Server.GetLastError(), HttpException)

        	' Verify the expected error.
        	If  (checkException.GetHttpCode = 500 and checkException.ErrorCode = -2147467259) Then
            		
			Server.ClearError()
            		
			' Redirect the user to the custom error page (ErrorPage.aspx).
           		HttpContext.Current.Response.Redirect("ErrorPage.aspx")
       		End If
    	End If
        
End Sub
