Hi, I am writing an MFC program in MSVC7 that must pass a path from one dialog box to another upon pressing a button. I attempt to pass the path to the next dialog by using a directory iterator: fs::directory_iterator startIt(scanPath); (***) where scanPath is an object of type path. PICtoolProgressWnd temp(this,startIt); I pass the iterator into the constructor for the second dialog. When I attempt to run this program, my program just hangs after clicking the button and I cannot exit it. The second dialog never appears. The only way out is to Alt-Ctrl-Delete out of the program. The only other clue given is that when the program freezes, the "xstring" file opens with a green arrow pointing at what appears to be a definition of operator= or something of that sort. I have commented out practically all of my code in the button click event handler and determined that when the iterator is declared, (***) above, the program freezes. When this line is commented out, the program responds. What could I be doing wrong?? Below is some more code: //Creating the dialog if ( temp.DoModal() == IDOK) { //Display results. } else { //Are you sure you wish to cancel this process? } //Second dialog constructor. PICtoolProgressWnd::PICtoolProgressWnd(CWnd* pParent /*=NULL*/, fs::directory_iterator start) : CDialog(PICtoolProgressWnd::IDD, pParent) { startScanPath = start; } //startScanPath is a member variable of type fs::directory_iterator. Your help is greatly appreciated. Thanks in Advance, Ryan --------------------------------- Do you Yahoo!? Read only the mail you want - Yahoo! Mail SpamGuard.
