'Save As' dialog box in ASP.NET....Urgent
On click of a button following logic is been executed which pops up an 'Save As' dialog box. When user clicks the button for 3rd time / more then twice the browser gets hanged. Why does this happen?
Private Sub DownloadFile(ByVal strFileName As String)
Dim objFilePath As String = Server.MapPath("/GrantDoc/Downloadable Documents/" & strFileName)
Dim objTargetFile As System.IO.FileInfo = New System.IO.FileInfo(objFilePath)
If objTargetFile.Exists Then
.ContentType = "application/octet-stream"
.AddHeader("Content-Disposition", "attachment; filename=" + objTargetFile.Name)
Catch objEx As Exception
Dim lobjCommCls As New GMS.ClassLibrary.clsCommonClass
marrError = lobjCommCls.fnReturnError(marrError, "", objEx, "DownloadFile()", False)
Throw New Exception

I don't see you releasing system resources here...
Aren't you supposed to be setting things like file references to Nothing for VB?
If this post contains any code, I may or may not have tested it. It's probably just example code, so no getting knickers in a bunch over a typo, OK? If it doesn't have basic error checking in it, such as object detection or checking if objects are null before using them, put that in there. I'm giving examples, not typing up your whole app for you. You run code at your own risk.
