Something like OpenDialog, but for a directory
Hi...
When I click a button, I want my app to display an OpenDialog box similar to selecting a file, but for selecting a *directory* instead (only show directories, not files). How can I do this?
Thanks
Shawn

Kotan,
How? What do I declare in Uses? SelectDirectory doesn't even exist in the help file. Can you give some more info?

My appologies, it does :)
That's a nice little function. Looks like a wrapper for the code I posted above (which I got from Madshi I think from memory).
Speaking of which, I just noticed an error:
function GetPath: String;
var
pl: PItemIDList;
folder : array[0..MAX_PATH] of Char;
bi : TBrowseInfo;
begin
Result := '';
FillChar(bi,SizeOf(bi),#0) ;
StrPCopy(Folder, PathEdit.Text);
bi.pszDisplayName := @folder[0];
bi.lpszTitle := 'Please Select a Folder';
bi.ulFlags := BIF_RETURNONLYFSDIRS;
bi.hwndOwner := Form1.handle;
pl := SHBrowseForFolder(bi);
if Assigned(pl) then
if SHGetPathFromIDList(pl, folder) then
Result := Folder;
CoTaskMemFree(pl);
end;
The Owner Handle was pointing to one of my forms.

SelectDirectory already exists,
(or was it selectdir)
i guess its in the sysutils-unit
meikl ;-)

SelectDirectory is in FileCtrl-unit
yep, kotan
the code stu posted is the nicest (IMHO) cause you can customize it by changing the TBrowseInfo structure.
add shlobj and activex to the uses for it to work.
also delete this line its not nessesary :
StrPCopy(Folder, PathEdit.Text);

Aztec,
Why don't you just make your own.
I've attached a unit file and a form file with the code.
Note:
1) This was done very quickly, you may want to enhance it.
2) When setting the directory of the dialog form make sure you send it the full path name, the path has to end with a file name (ex c:\temp\test.txt) or a directory ending with a "\" (ex. c:\temp\ )
Hope this helps

I guess the only reason I'd suggest using what I posted over a custom form is that it keeps the "windows" feel. In other words, it looks like every other application's directory browser.
Thanks for pointing out the bit of code I left in there, Barry. Oops :)

What about adding a callback to display the situation to the user?
ASKER
Kotan - that works pretty nicely, thanks. Anyway to suppress the file listing somehow?
Maybe there's a 3rd party custom component out there that does this?
Thanks

No I didn't Stuart - Kotan's seemed like the quickie solution I was looking for. Yours will suppress the file listing?

Can't find any info in Help under TBrowseInfo Stuart. Does it exist in Delphi 3 Pro?

It depends on how you code it. The way I presented the code to you now displays a dialog box with directories only. You can suppress or display the files if you wish by changing the TBrowseInfo flags.
Sometimes the quickest way isn't always the best way.

Aztec,
Seem like there are 2 version of SelectDirectory(). One will show files and the other one is not.

Try this:
function GetPath: String;
var
pl: PItemIDList;
folder : array[0..MAX_PATH] of Char;
bi : TBrowseInfo;
begin
Result := '';
FillChar(bi,SizeOf(bi),#0)
StrPCopy(Folder, PathEdit.Text);
bi.pszDisplayName := @folder[0];
bi.lpszTitle := 'Please Select a Folder';
bi.ulFlags := BIF_RETURNONLYFSDIRS;
bi.hwndOwner := ExportToParadoxForm.handle
pl := SHBrowseForFolder(bi);
if Assigned(pl) then
if SHGetPathFromIDList(pl, folder) then
Result := Folder;
CoTaskMemFree(pl);
end;
Hope this helps,
Cheers,
Stu.
