Getting An Other File Extension As Default Instead Of All Files As Default Extension?

Jun 25, 2009

I am using VB 08 running an openfiledialogue wanting to get the result of the GDS file (*.gds) to be the default extension at the drop down menu instead of All file when the openfiledialogue box opens.

I coded it with:

OpenFileDialogue.Filter = "GDS File(*.gds)|*.gds|All files|*.*"

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?

Compress The File Without Loosing File Extension Inside Compressed File

Jan 4, 2011

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.

I use this code :

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

Or using this code :

Public Sub cmdCompressFile(ByVal FileName As String)

'Stream object that reads file contents
Dim streamObj As Stream = New StreamReader(FileName).BaseStream

[CODE]...

I need to compress the file without loosing file extension inside compressed file.

Error - Catch Cannot Catch Type 'Microsoft.Office.Interop.Outlook.Exception'

Mar 25, 2011

I have a program in VB.Net that receives mails from Outlook, extracts attachments and inserts the attachments into a table through a query. I would like to put the query/queries in a Try/Catch block, but cannot do so as Outlook exceptions cannot be caught, and it gives me an error, and unless I put a very specific exception, I cannot catch it. Is there a workaround?

Edit:

Try
Catch ex As Exception
End Try

Exception is underlined and when I hover on it, it says: "Catch cannot catch type 'Microsoft.Office.Interop.Outlook.Exception' because it is not in 'System.Exception' or a class that inherits from 'System.Exception'". This is affecting all my other code which I'd like to put into a Try/Catch block.

Catch Log4net Exceptions / Use Try / Catch Approach

Jan 23, 2012

I need to catch log4net exceptions (its own exceptions not app exceptions logged by it). I wish there's a way of doing it this way: [code] I have this code implemented and there's no errors in compilation but i force log4net to have an error (pointing to a non existing database in the config file) and nothing is threw.I've tried the listener aproach: [code] and it's writing the errors to log4net.txt, the forced ones i mean.This last aproach has a couple of drawbacks: it won't append every error to the file, if the error is the same it doesn't write it, i can't get the listener to write every error to that file, only one (I don't know how to fully configure the trace listener, it might be that). Thus it won't append the date and hour to every line wich is a necesity for me. Finally i can't give structure to it (xml). Even if the listener work i need to use the try/catch aproach, since i'm using ExceptionHandling from Enterprise library to log the errors in my app.

Use An Extension Method Instead Of Just Creating Non-extension Sub Or Function?

Dec 3, 2009

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?

Downloading File Without Extension?

Jan 17, 2010

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.
