ch8 FolderBrowserDialog strange behavior

Silas Tomkyn Combermache · January 14th, 2012, 12:29 AM

I have done some win32 programming with another version of basic. In the past, I have used an environment variable and then concatenated a string to get the filepath (string to plug into file info structure) that I desire. This technique does not work here. I know I am getting some kind of enumeration but I don't know what to do about it.

The example or project on page 273 uses the line shown below for the "RootFolder" of the FolderBrowserDialog which I changed while I was fooling around with the code to see how I could use it for my own programs. That is what I like about this book, you can twiddle with the code and watch the debugger while reading the "How it works" to see how things . . . um . . . work.

Code:

rem original line in book below, works fine
.RootFolder = Environment.SpecialFolder.MyComputer
rem changed to: (this does not work)
Dim mystr As String
            mystr = Environment.SpecialFolder.Windows
            mystr = mystr + "system32"
            'MsgBox(mystr)

rem this works:
    .RootFolder = Environment.SpecialFolder.Windows
rem but I want a folder below this.

Why won't my code change work?

Somehow I get an integer instead of a string. How can I use the specialfolder method to get to system32 or anywhere I want? I might want to use relative addressing from some common folder like "windows" or the user "documents" folder as a starting point.

thanks,

Bro sorry I maybe way off. i'm just starting this book but I did mess around with 2008. I could be wrong but I see 2 possible problems.

1. you are setting a folder object to a string variable. see if ".tostring" is available here.

Quote:

mystr = Environment.SpecialFolder.Windows

2. You are forgetting the / when adding system32 folder.

Also check this page out. There are other options to get the system folder other then appending to a string!!
