my situation is this; I have a search button which searches records with Surnames, when two or more records have the same surname, the first record appears and 4 navigational buttons appear, they are 'Go back to first record' (btnFirst), 'go back one' (btnPrevious), 'go forward one' (btnNext) and 'go to the last one (btnLast)'. All of these work properly except for 'go back one' (btnPrevious). When I click this and the record is currently the first one, the program crashes. Its probably a very elementary mistake but I can't figure it out. Here is the code for btnPrevious

I was just wondering if there exists somewhere, a list of all open forms that you can view during debugging?Alternatively, is there a quick piece of code to close all non visible forms?

I have a standard scoring algorithm but I need to help on a piece of code to only execute the scoring algorithm at certain times.I want it to be triggered by dates, but the problem arises if the program is used after 2 (or more) dates have passed, the first date will not be added as the second date is the newest and therefore the one that triggers the scoring algorithm. - The scoring algorithm gets the scores for that week, which are stored in a text file.

View 3 RepliesI'm looking for a more elegant way to work around a problem I have
Code:
Private Sub MnuCheckForUpdates_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MnuCheckForUpdates.Click
Dim startInfo As New ProcessStartInfo(mStartUpPath & "" & "Updater.exe")
Process.Start(startInfo)
End Sub
As you can see I�m calling my updater program, but I want some code to run only after the Updater has closed.My work around was to:
A - Initially load the updater.
B � Start a time
C � Check if the updater is still running.
D � If its not call the routine in the timer event.
But this is not elegant is there another way around this, I can call events in the updater but I don�t think I can join them in someway to ProcessStartInfo Class .
I have made a program that has an intro screen, moving onto an activity select screen which acts as the main interface to get around the program. After creating the program and installing it on my computer, when I close the program from the activity select screen, using the "X" at the top right corner, the program continues to run under "processes" in the task manager.If I close the program from the intro screen though, it will close everything, including the processes. Is there anyway I can get the same to happen with the game select screen? I can make it work by putting my own "End" button on the form, but id prefer to be able to do it with forms own close button.

View 14 RepliesOk, So I am making a front-end for a program, and it runs the exe with command line arguments. One of those arguments is creating a log file that tells me who the winner is. Currently I have code that runs the app, tell VB when it exits and then does another event. When testing with message box as the other event, works fine.
When running the System.IO.Streamreader the app just closes down on its own and there are no errors shown.

View 1 RepliesDoes anybody know if it's possible to make your program 'self-destruct' (delete itself) when it closes? I know this sounds like malware, but it's not. What happens is the user clicks 'install', the application copies itself to another directory, then the application starts the new copied file, with an argument that begins the installation, kills itself, and then the copied application restarts and then it's done. But I can't get rid of the original executable.
