Hello,

Could you please review a fix for the following issue:

The fix is available at:

lpstrFile should be treated as double NULL terminated (DNT) string only when OFN_ALLOWMULTISELECT flag is set.

If the *OFN_ALLOWMULTISELECT* flag is set and the user selects multiple files, the buffer contains the current directory followed by the file names of the selected files. For Explorer-style dialog boxes, the directory and file name strings are *NULL* separated, with an extra *NULL* character after the last file name.
Currently we check length of a lpstrFile with GetBufferLength() which treats \0\0 as an end of a string. It works nice, unless we call setFile() with a filename longer than a path of a saved file (in single-select mode). In single-select mode lpstrFile string ends with single \0, and GetBufferLength() fails to find correct length and we pass \0-separated buffer to WFileDialogPeer.handleSelected() which will be treated as multi-select mode.
