    Re: Unicode characters in VC++

    Those errors give you the answer. The answer is: you are not able to set unicode text via that class method, because conversion to std::string implicitly occurs, and std::string is able to deal with...

    Then you should start wanting to create an exe able to run service mode. Regular exe is not able to do that. :)

  5. Re: How to insert and read image from database (sql server) using MFC ?

    Confused about what? Clicking menu item results in sending WM_COMMAND with the item ID. Same to clicking button or toolbar button. This is the most elementary basics of Windows programming.
  8. Re: A question regarding creating a window

    You should revise your approach and stop thinking about executing some code after message pump loop. Instead, you should focus on other possibilities. GUI programming really differs from what you...

  10. Re: MFC Proper usage of sending message to dialog to activate

    Nope. Windows design allows sending messages across threads alright. You have to do that with caution of course, but you can SendMessage from a thread other than the one the window was created in....
  11. Re: MFC Proper usage of sending message to dialog to activate

    Just be accustomed to deal directly with MSDN. :)

    Re: Removing title bar from external app

    It definitely depends on the app you fumble with. What looks to you like titlebar may be a self-painted region which appearance is controlled by the app itself but not window style. :) As others...
  14. Re: [C\C++ 11 - win32] - how getting the menu handle and menu item position?

    You definitely need to gain some skills in debugging. Get some reading on the techniques. Go through documentation, your IDE or third party debugger.

  18. Re: What are CRT file descriptors in Windows?

    Did it ever occur to you how much vague and ambiguous this sounds? Do you mean there should be some third process spawning the other two? Should those processes be running different executables or...
  24. Re: Passing NULL to FindResource() might not work?

    If so, this would mean somebody fail to read or understand MSDN article, as the article is 100% clear about this particular situation. Not 99% or something, but 100%. :)
