I have this function I put together with help online and it works just fine until the program runs over night. 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 am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

I have a functioning program that has been completed that based on miles and gallons used, both will display the individual MPG for each single entry as well as compile a total for the miles, gallons used and overall MPG at the bottom.My problem is that when 0 is entered for fuel, the MPG calculation says Infinity and 0 is placed in the gallonsUsedListBox.I've been trying to get the statement "Gallons must be greater than zero" into thegallonsUsedTextBox by utilizing an If..Then statement but to no avail. I'm not sure where to input it or if my avenue of using the If..Then statement is even on track. Here is the code I have:

I created a simple program which basically launches programs installed on 32-bit system in the C:Program Files directory. I purposely put an .exe line of code in the compiler but that .exe wasn't installed on the system, I was expecting for an error when I tried to click the launch button and I did. NOTE: I already have a beginning If statement and that program is actually installed in the system, works perfectly no errors appearing.
ElseIf lstMultimedia.SelectedItem = "HyperCam" Then Process.Start("C:Program FilesHyperCam 2HyCam2.exe") 'this program doesn't exist in the system"
When the error appeared I looked at it in detail and found it was a system.componentmodel.win32exception type of error, I'm guessing that means a file doesn't exist in the directory I specified therefore the program displays an error.Now what I want to do is display a message box saying along the lines "This program cannot be found in your system" or something like that. But I don't know what the actual syntax/code for it, so far from thinking I have this.
Else : lstMultimedia.SelectedItem = 'no idea what to put here Then MessageBox.Show("This application cannot be found in your system or is installed in a different directory", "Error", MessageBoxButtons.OK, MessageBoxIcon.Error)

View 3 RepliesI am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")
