Hello,
when using DirSelectPopup, files are visible and can be selected by the user. The function will only return a directory, but I totally agree with you that this is very confusing for the user. There should be an option to hide the files for the user.
A possible solution to your problem is creating a Directory Selection Popup panel yourself, using a File Browser control (Custom Controls -> Toolslib Controls -> File Browser). This is actually a tree control, converted into a File Browser. The File Browser function panel is located here: C:\Program Files\National Instruments\CVI80\toolslib\custctrl. Note that the CVI80 directory name is different for each CVI version. In this function panel you will find the FileBrowser_Create function, which transforms the Tree control into the file browser. Now you can use the FileBrowser_SetAttribute function to change the File Browser's attributes. This way you can enable the 'Browse Directories Only' option.
A disadvantage of using this file browser is that it doesn't look very need, and you have to program the whole thing yourself.
Good luck,
Wim
