有没有win32编程因为打印变量调试程序而头疼呢.方法二的函数完全类似printf.非常完美.
方法一:
不带参数输出如printf("hello world");

OutputDebugString("debug");

 case WM_COMMAND:

 wmId    = LOWORD(wParam);

 wmEvent = HIWORD(wParam);

 // Parse the menu selections:

 switch (wmId)

 {

     case IDS_BTN1:
OutputDebugString("1");
         break;

     case IDS_CLEAR:

         SetWindowText(GetDlgItem(hWnd,IDS_EDIT),(LPCTSTR)"");

         break;

     case IDM_ABOUT:

         DialogBox(hInst, (LPCTSTR)IDD_ABOUTBOX, hWnd, (DLGPROC)About);

         break;

     case IDM_EXIT:

         DestroyWindow(hWnd);

         break;

     default:

         return DefWindowProc(hWnd, message, wParam, lParam);

 }

 break; 

 #include <stdio.h>

 void __cdecl odprintf(const char *format, ...)

 {

     char buf[], *p = buf;

     va_list args;

     va_start(args, format);

     p += _vsnprintf(p, sizeof buf - , format, args);

     va_end(args);

     while ( p > buf && isspace(p[-]) )

     {

         *--p = '\0';

         *p++ = '\r';

         *p++ = '\n';*p = '\0';

     }

     OutputDebugString(buf);

 }
