I cannot seem to be able to manipulate the multiple files I select while using the common dialog <TOpenSaveDialog>.  I use the following code:
TOpenSaveDialog::TData *pWndwFileOpenData;
pWndwFileOpenData =
new TOpenSaveDialog::TData(OFN_PATHMUSTEXIST |
                           OFN_HIDEREADONLY  |
                           OFN_FILEMUSTEXIST |
                           OFN_ALLOWMULTISELECT,
      "Report Files(*.rep)|*.rep", 0, "", "REP");
enables me to set up the common dialog box in order to execute it.  But despite being able to execute it I cannot - or better yet do not understand how to use the multiple files that I selected from the open dialog box.

Please Help!!!

The TData structure does not contain any fields to put multiple in, so they all go in the one filename field. Since OWL usually simply wraps around the WIN32 API it's likely to be the same. Look in the Win32 online help for the OPENFILENAME struct. Under Flags/OFN_MULTISELECT and you'll read:

When this flag is set, the lpstrFile member points to a buffer containing the path to the current directory and all filenames in the selection. The first filename is separated from the path by a space. Each subsequent filename is separated by one space from the preceding filename. Note that for the new Explorer-style dialogs (dialogs that have the OFN_EXPLORER flag set), a single null character, \0, separates the filenames, and two null characters, \0\0, terminate the entire string.

I suppose you'll be able to find out the details (I've read somewhere that with OWL the filenames are separated by \0) and hope this helps.
