    How to open files from list?

    Code:
    #include <windows.h>
     
    #define ID_EDIT 1
     
     
     
    LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)

      static HWND hwndEdit;
      static int len;
      static TCHAR text[30];
     
     
      switch(msg)
      {
        case WM_CREATE:

                                    65, 10, 150, 20, hwnd, (HMENU) ID_EDIT,

                  }
               if (LOWORD(wParam) == 3) {

            break;
     
            case WM_DESTROY:
                    PostQuitMessage(0);
            break;
      }
      return DefWindowProc(hwnd, msg, wParam, lParam);
    }
     
    int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance,
                            LPSTR lpCmdLine, int nCmdShow )
    {
      MSG  msg ;    
      WNDCLASS wc = {0};
      wc.lpszClassName = TEXT( "Edit Control" );
      wc.hInstance     = hInstance ;
      wc.hbrBackground = GetSysColorBrush(COLOR_3DFACE);
      wc.lpfnWndProc   = WndProc ;
      wc.hCursor       = LoadCursor(0,IDC_ARROW);
     
      
      RegisterClass(&wc);
      CreateWindow( wc.lpszClassName, TEXT("Edit control"),
                    WS_OVERLAPPEDWINDOW | WS_VISIBLE,
                    220, 220, 280, 180, 0, 0, hInstance, 0);  
     
      while( GetMessage(&msg, NULL, 0, 0)) {
        TranslateMessage(&msg);
        DispatchMessage(&msg);
      }
      return (int) msg.wParam;
    }
    How can i do that

    07106 = O:\BREZ\MSKAM\MSKWMF\M156.WMF
    08124 = O:\BREZ\MSKAM\MSKWMF\M825.WMF
    09210 = O:\BREZ\MSKAM\MSKWMF\M1480.WMF
    92446 = O:\BREZ\MSKAM\MSKWMF\M793.WMF

    And after i type 07106 in the text box and press buton it opens this file O:\BREZ\MSKAM\MSKWMF\M156.WMF or if i type value wich is not in that list it shows me ERROR ?

    Code:
    struct filenumandname
    {
        int num;
        string name;
    };
    
    ...
    
    struct filenumandname fnn[] =
    {
        { 7106, "..." },
        ...
    };
    Run through the list looking at each number to see if it matches. If so, open name.

    Edit: Since you're using 0 prefixed numbers some time, you may just want to use a pair of strings. If you do that, you can skip the structure and use a 2d array of strings:
    Code:
    string [][2] =
    {
        { "num", "name" },
        ...
    };

    Hope is the first step on the road to disappointment.
