C++ method for handling keyboard input

In this paper, the example of C++ processing keyboard input method, can achieve a simple process of keyboard input, to share for your reference. The specific implementation method is as follows:

Need to respond to WM_CHAR message:

#include <string>

static std::string str;

In the wm_char:

str = str + char(wParam);  

::InvalidateRect(hWnd, NULL, 0);  

return 0;

 
In the wm_paint:

case WM_PAINT:  

    hdc = BeginPaint(hWnd, &ps);  

    //TODO: add arbitrary drawing code here... & have spent < br / >
    ::TextOut(hdc, 0, 0, str.c_str(),str.length());  

    EndPaint(hWnd, &ps);  

    break;

Hope that the article described in the C++ programming to help you.
