My simple but useful code bank



In Visual Basic 6 app.path is used here is the Visual Basic 2008 code:

Code:

Application.StartupPath()

Checking for file existence.

Code:

System.IO.File.Exists()

Now those are both going to give you errors but if we mix them and use:

Code:

If System.IO.File.Exists(Application.StartupPath() & "\file.extension then

You get no errors and it will check for the file now lets say you need to create a file:

Code:

System.IO.File.Create(Application.StartupPath() & "\file.extension")

Now lets say you want to find out if a folder exist:

Code:

System.IO.Directory.Exists()

Now what if you want to create a folder:

Code:

System.IO.Directory.CreateDirectory()

Now at the moment this code will again give you errors.
so id you put the too together you can get:

Code:

Public Class Form1
    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        If Not System.IO.Directory.Exists(Application.StartupPath() & "\test") Then
            System.IO.Directory.CreateDirectory(Application.StartupPath() & "\test")
        End If
    End Sub
End Class
