    Ah, so call CommDlgExtendedError() and see why.

    Well I did some error checking and found out that CommDlgExtendedError() returns CDERR_STRUCTSIZE, this means that:

    The lStructSize member of the initialization structure for the corresponding common dialog box is invalid.

    ofn.lStructSize = sizeof(ofn);

    What's wrong with that?

    Try changing...
    Code:
    ofn.lStructSize = sizeof(ofn);
    ... to...
    Code:
    ofn.lStructSize = sizeof(OPENFILENAME);
    ... and see if that works. If it doesn't work, tell me what OS version you are using.

    >>I'm using borland C++ 5.5 compiler<<

    If you are using bcc5.5 cmd line tools with win9x/nt and have not set up your configuration files correctly then the kind of problem you are experiencing will typically occur.

    Read my post in this faq for further information.

    I never had any problems before that, all controls and dialogs worked...


    And, the CDERR_STRUCTSIZE is still there, after I changed the size... So, I'm running win98 second edition

    ofn.lStructSize = sizeof(OPENFILENAME);
    ... to...
    Code:
    ofn.lStructSize = sizeof(OPENFILENAME_SIZE_VERSION_400);
    ... and see if that works.

    Ken is thinking along the same lines as me, a number of structures have been changed by MS, particulaly after 0x0400. This was one of them.

    Nothing... still the same error.

    adrianxw, you know I think I'm up to something... can you download http://www.winprog.org/tutorial/files/source.zip and run app_two.exe (it's located inside the zip), then try to FILE->OPEN inside app_two.exe

    You see, because app_two uses GetOpenFileName(), but the FILE->OPEN doesn't open me anything, no dialog not nothing.
    Check it out, and let me know if that works for you.


    Thanks

    If you use bcc5.5 and you compile and run your program which contains common dialogs on win98 (generally win9x/nt) and you have not defined:
    -DWINVER=0x0400
    -D_WIN32_WINNT=0x0400
    in your bcc32.cfg file then your common dialog will not appear.

    Do you have those macros defined in your bcc32.cfg file? If not, put them in and recompile - your common dialog (file) will show, provided there are no other errors in your code.

    If I try to run the .exe on my Win95 machine, it behaves as you suggest, however, when I compile it, (after fixing a couple of things that MSVC grouched about), it worked as expected. On my WinXP system the .exe runs.

    I am quite sure your problem is with the changed definition of the OPENFILENAME structure. Try what Ken is saying, you somehow need to make sure that your compiler knows which version of the structure you need.

    I often find myself putting a #define for _WIN32_WINNT in programs.
