Requirements for this Issue

The source code in this issue is designed for all versions of Visual Basic.

In this Issue

This issue shows how to manipulate the backslash on path names. It is most useful for processing the path name returned from App.Path. It might come as a surprise to some readers, but the App.Path property does not always return a path name without a backslash as most people expect.

If the application is installed in the root of a drive, such as W:\, App.Path will return W:\. If it is installed in a directory it will return something like C:\APPDIR, without the backslash.

For your programs to work correctly you must account for both situations. The two functions introduced in this issue provide an easy way to do this.

AddBackslash or RemoveBackslash

Public Function AddBackslash(sStr As String) As String
Public Function RemoveBackslash(sStr As String) As String

Parameters

Return Value

The converted string (either with the backslash or without backslash)

Sample Usage

We will demonstrate examples of both of these routines. Assumes App.Path is equal to C:\COTW

Example for AddBackslash

Dim sPath As String
sPath = AddBackslash(App.Path & "filename.txt")
sPath will be equal to C:\COTW\filename.txt

Example for RemoveBackslash

Dim sPath As String
sPath = RemoveBackslash(App.Path & "\filename.txt")
sPath will be equal to C:\COTW\filename.txt
