Remarks
Displays the standard dialog box used to select a file for opening. This method allows accessing filenames containing Unicode characters from development environments whose common dialog components don't manage Unicode natively like the "Microsoft Common Dialog Control" (ComDlg32.ocx) used by Visual Basic 6.
After choosing an input file, you can access more detailed information about it through the CommonDialogGetInfoFromLastOpen method.
For further information about dealing with Unicode characters, check the How to manage Unicode characters in filenames and tags tutorial.
