I have a VB.NET program with a SaveFileDialog control with the filter set as ".asx|*.asx|.m3u|*.m3u" (without the quotes). It works fine to save a file, but if I then try to save a file with the same name of an existing file and then change the extension in the save as type box, it still thinks I want to save the file as the existing file and asks to overwrite the file, disregarding the newly selected file extension.
I have tried setting the SaveFileDialog.FileName = Nothing after saving a file, so the Save File Dialog Box the File name box is empty, but then I like to click the existing file to get the file name I want, then select a new extension and try to save, but it still asks to overwrite the file with the other extension.
I hope my situation is clear and sorry if it has been already asked a million times...but can anyone point me in the right direction or tell me how I can save the file with the currently selected extension, not the previous selected extension when the file name was entered?
Code:
If SaveFileDialog.ShowDialog = Windows.Forms.DialogResult.OK Then
If Path.GetExtension(SaveFileDialog.FileName) = ".asx" Then

but the results i get in the open file dialogue box remains as all files being in the drop down menu as the default file extension. How to i set it to ".gds" format?

I have File Like "Sample.bak" and when I compress it to be "Sample.zip" I lose the file extension inside the zip file I meann when I open the compressed file I find "Sample" without any extension.

Dim source() As Byte = System.IO.File.ReadAllBytes(filePath)
Dim compressed() As Byte = ConvertToByteArray(source)
System.IO.File.WriteAllBytes(destination & name & ".Bak" & ".zip", compressed)

Public Sub cmdCompressFile(ByVal FileName As String)
'Stream object that reads file contents

I have had several occasions recently to access a specific class several times over a relatively small time frame.So I've been storing the value of the class in Session and trying to access it on page load, if it's not available creating a new instance and storing that in session.
So instead of constantly replicating the same code for different classes on different pages I'm trying to create an extension method to do this for me.
[Code]...
I'm stuck on what to do when I make my new instance of my class (it would have to have a New() sub)
I'm not sure where to go from here... or even if this is the best way to do it.

<asp:RequiredFieldValidator SetFocusOnError="true"

I need to get the extension part of a file path for example,
c:me.jpg
i need to return the ".jpg" to a string. Im sure this is easy enough, im guessing i need to get all the text after the last .
Why would I use an extension method instead of just creating non-extension sub or function?
For ex, I could have an extension function called IsNullOrEmptyOrAllSpaces on String, which does a check as its name implies. Or I can write a stand alone function that does the same thing. Other than having the extension show up in Intellisense, is there any advantage? Is a call to the extension quicker/more efficient than a call to a regular function?
Do you have some source code how to open a file (file browser) with file extension specific using Visual basic.net.
Just need to get the path then control this using the vb.net binding

I'm trying to save this picture from a website automatically, but the problem is there is no file extension. I tried the following code, but it always gives me an error:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
My.Computer.Network.DownloadFile("http://www.hackthissite.org/missions/prog/2/PNG/", "C:PNG.bmp")
End Sub
Error: An exception occurred during a WebClient request.
P.S - I believe the reason it doesn't have an extension is because the picture changes each time the url is loaded (probably through a php code). I'm not too sure on the specifics, but the lack of an extension is what I am having problems with.
