Is it possible to create a WIN32 app with a window having a title bar and a [X] close button BUT NO system menu.
Or do I have to have a dialog box as my main.

Thanks,

Just don't specify the WS_SYSMENU window style.  You probably want to specify WS_CAPTION WS_OVERLAPPED WS_THICKFRAME and maybe WS_MINIMIZE and WS_MAXIMIZE.

Let me know if you have questions.  (If that doesn't work, There is another way, but i think that will)

As I said, there was a possibility that that would not work, try it again with the same styles but also specify a WS_DLGFRAME.  (Ignore the documentation for WS_DLGFRAME that says you can't have a title with it.  You can.  That is left over from windows 3.1)

I create such a window in my programs.  The styles I use are

 WS_POPUPWINDOW | WS_DLGFRAME | WS_THICKFRAME | WS_OVERLAPPED | WS_CLIPSIBLINGS

You can remove the clip sibblings style.  My window has a caption although I didn not specify the WS_CAPTION style.  It does have a close box but does not have minimize and maximize buttons.  (these can be added with the WS_MINIMUZE and WS_MAXIMIZEstyles)  It has no system menu.

I have a close button on mine.  However, I use CreateWindowEx() and specify two extended styles.  WS_EX_DLGMODALFRAME and WS_EX_WINDOWEDGE.

You might try that or you might try adding the WS_CAPTION style.  (Which probably should have been there, but actually isn't in my code.)

Thanks
CreateWindowEx() does it, CreateWindow() does not.
