I want a message box to show when a username doesn't exist. I figured this would work but an error shows saying 'FileNotFoundException was Unhandled', for the fist line.
Dim UserFile As New System.IO.StreamReader(sPath & "" & UsernameBox.Text & ".txt")
Username = UserFile.ReadLine
Password = UserFile.ReadLine

I use Visual Studio 2003, VB.net, NetFramework 1.4 and Windows XP I have been using the following Code Snippet for a number of years in both Web Services and Windows Applications. However suddenly around the 29th September 2010 it has stopped sending E-Mails from both Web Services and Windows Applications. The same problem has happened not only to my own Network but on two other Networks, one using XP as its Server and the other using Server 2003. All 3 of these are using different ISPs.

When i click my button and 3 labels have a value in them, even thought they are equal to less than 17 and less than 21 a message box doesn't appear. [Code]

I don't think it is night time that is the problem, just the long run time. I take bitmaps and place text on them then convert them to icons so that the image can be used on the system tray.

I'm trying to make a game, pretty much a game like memory where you flip over a card and find the match. But because of how many buttons I need I was wondering if it was possible to show the picture in a message, all the pictures are funny motivational posters from photobucket so I want the player to be able to read the dialog. I've already tried doing
Dim picture as string = "1.jpg"
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
MessageBox.Show(picture)
End Sub
but when I click the button nothing happens and yes the name of the picture in my bin folder is "1". I am using Microsoft Visual Basic 2008 Express Edition.
I have a collection similar to:
Public Class MyCollection
Inherits ObservableCollection(Of MyCollection)
Private _Name As String

EDIT: I know that I can use DebuggerDisplay, but unfortunately it is very limited. The class in reality is quite complex and I need to have the possibility to define a logic in what I show during debugging, if possible.

Private Sub btnCalculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCalculateTotalPay.Click
' declare variables
Dim hours As Double

How do you make the image in a picturebox vanish when you change an option? I have tried a few different ways that i have seen but none have worked. I have it set so when i change an option in a listbox it will change the picture and data in other controls, however one option in the listbox has no data to fill in those controls and so gets left blank. However when i click on that option right now the images that were in the picturebox before get left behind until i click on another option that has a picture. So how do i remove the picture from the box?

View 8 Replieswhen people first run my program (as in the FIRST EVER time they run it), I want a window to popup (Form4). In this Form you have to locate a directory to a certain program (my program uses this program) and press OK, and then that will generate a .txt file with the directory to the program. (So that my program knows where that program is located.) Now, what I want it to do is when you open up the program, upon load (Form1), I want the program to check if that text file (directory.txt) exists. If it does and the path in the file is correct, the program will run fine. If the text file is missing and/or the directory doesn't exist, it will bring you back to Form4 (assuming that this is your first time running the program since the directory.txt file doesn't exist).

When I launch VB Help and do a search it shows under "Local Help", "Exception from HRESULT:0x8004032E". It lists three results under "MSDN Online", but the large field to the left of it is entirely blank. If I double-click blindly in that blank area it brings up various topics as if they were listed there but invisible. Further, the region under "Contents" is also blank, as is the "Filter by:" field. If I click the down arrow by the "Filter by:" field it brings up an entirely blank menu. If I then click outside the menu box it brings up a message saying "The selected filter contains an error that prevents it from being applied.". What's wrong and how can I fix it?

View 4 RepliesI am using the DownloadDataAysnc. But the ProgressChanged event doesn't show progress until after the data has been downloaded.Even when I try and download a data which is contained in a big file. The programs remains responsive so I know it is doing something.However, it is when the progress has completed that the progressChanged event fires.I known this as the progressChanged and the DownloadDataCompleted fire immediately after each other. However, they should be a pause as the file is quite big.This is the code snippet I am currently using. And the output below
