View 2 Replieswhat is probably a very stupid and basic question, I'm new to Visual Basic I currently coding a program which deletes specific files that are part of a game.

The problem is the filepath to My Documents includes a username which is unique to different users, meaning on any other pc the program will not work.
The path on my computer is: C:UsersShaneDocumentsElectronic Arts
How can I get the program to find this folder on other computers? I'm totally lost.

View 3 RepliesI'm trying to delete all the files in the same folder that have the same name but different extensions, such as CurrentWallpaper.bmp, CurrentWallpaper.jpg, CurrentWallpaper.png, without putting them in a separate folder. How could I go about doing this? I tried doing
Dim bg As String = dir + "" + Login.UsernameTextBox.Text
Kill(bg + "CurrentWallpaper.*")
