I have created a custom action that modifies a application config and configures a path into the configuration file. I have a custom text page added to the UI of the setup to prompt the user to enter the path.

The issue is that if the user does not terminate the path with a \ an error is generated from the setup runtime. This is similar to if you do not specify the \ after the TARGETDIR property ("[TARGETDIR]\"). I am putting the \ after the property in the custom data field, but it is the user input that causes the error. Is there a way to insure that the add the slash to the property if it is missing?

Hi John E Bailey,

Based on my understanding, we do not need to have the users type the path correctly. We can correct the text after we get the text from the UI to make sure the path ends with a ‘\� This is a code snippet:
string path = GetPath();

//Add '\' if the path does not end with '\'

if (path.EndsWith("\\") == false)

path += "\\";

Please feel free to tell me if I misunderstand you.
