    messagebox loop

    Code:
                          bool close = false;
                        while(close == false)
                        {              
                        if(MessageBox(NULL,"ONLY THE LUBEMAN CAN CLOSE THIS!!!!", "So Are You The LUBEMAN???",
                           MB_YESNO | MB_ICONERROR == IDYES))
                           {
                           close = true; 
                           }
                           else if(MessageBox(NULL,"ONLY THE LUBEMAN CAN CLOSE THIS!!!!", "So Are You The LUBEMAN???",
                           MB_YESNO | MB_ICONERROR == IDNO))
                           {
                           close = false;   
                           }
    ok when i click close it just closes after asking the question it doesnt loop if i say no or anything? its like it just reads it and completely ignores the fact that IF then do this is there a reason it does this or what am i missing?

    it completely skips the else if only asking the question once i just cant get the question to ask and if it says no then loop back if it says yes then exit and go destroy the window. i have no clue why its like the messagebox if's seem immune to the fact that { } normally ment follow these instructions only if ID_YES is done and its just done regardless.

    any reason for this??? thanks

    ive fiddled with this for a while and this is just the curent result im running with

    You only want to call MessageBox once, and check its return value:
    Code:
      bool close = false;
      while(close == false)
      {              
      if (MessageBox(NULL,"ONLY THE LUBEMAN CAN CLOSE THIS!!!!", "So Are You The LUBEMAN???", MB_YESNO | MB_ICONERROR ) == IDYES) 
      {
        close = true; 
      }
      else 
      {
         close = false;   
      }

    Well if your not using the console window in the background why not tell your compiler to compile for Win32 Application, thus not even showing the console box.

    Here is my little and very simple MessageBox loop:
    Code:
    #include <windows.h>
    
    char Name[100] = "Uncloseable";
    
    int main()
    {
        for(int i; i;)
        {
        SetConsoleTitle( Name );
        HWND hwnd = FindWindow( NULL, Name );
        ShowWindow(hwnd, SW_HIDE);
        ::MessageBox(0,"You can't close this!","Uncloseable",MB_ICONWARNING);
        }
    }

    Ok I'm just going to guess your using Dev-C++, if your not it will probably be similar. Open up Dev and go to Options>>Compiler Options>>Linker(the tab)>>Check the box that says Compile for Win32 Application.
