I have this code where I was able to display files in listbox from open file dialog box.

here's part of it:
CODE
If .ShowDialog() = System.Windows.Forms.DialogResult.OK Then        
                For Each file As String In .FileNames  'Loop through the file names

                  Listbox1.Items.Add(file)  'Add files to list box



How do I add this line

CODE
  ' newfile = System.IO.Path.GetFileNameWithoutExtension(file)


to prevent listbox from displaying file extension, while its full path is still there for me to open the files ?



Many thanks if theres someone who can guide me. smile.gif

Try this


vb

Listbox1.Items.Add(System.IO.Path.GetFileNameWithoutExtension(file))  'Add files to list box


But be aware, if the extension isn't on the file then your system cannot open it (because it's cant guess what type of file it is)

Oh..opening of files, I just add

CODE
fullpath = System.IO.Path.GetFullPath(selectedfile)


when I want to open the files.
(more of trial and error but surprisingly, it works)

That could work where there is only one possibility.

It COULD get confused if you say had two or more files with the same name without extension. Say you had a setup.exe, setup.inf and setup.bmp file which extension is the app gonna add on the end to run??

so by adding this :
CODE
fullpath = System.IO.Path.GetFullPath(selectedfile)


It will be alright right?
Cos it will give full path of filenames.

Personally I think you could hit problems.

Say you have three entries in the list box which are

c:\setup
c:\setup
c:\setup

These are setup.bmp, setup.exe and setup.inf respectively.

Thats all good - until you click one of them. The user wants to run setup.exe. Firstly he doesn't know which one that is. You could make the assumption it would be the second one as the chances are it would be alphabetic. But when you run the code:

CODE
fullpath = System.IO.Path.GetFullPath(selectedfile)


It could return any of the three files mentioned.

Do you get what I mean it's kind of hard to explain.

hello.

Yes. I get what you mean.

But I dun think that will be a problem in my case, as my project involves opening only text files, and I have use filter for open file dialog to open text files only. smile.gif

Thanks for the tip btw smile.gif

if you would want to avoid the problem i think you can set the exact value with the extention within an array, and instead of directly acting from the listbox, you simply use the listbox as a link to the real filename in the array with the
matching index.
This way you can avoid the multiple value problem
i guess :s
