窗口过程里的默认项你没写 帮你写上了 也有注释 #include<windows.h> #include<stdio.h> LRESULT CALLBACK winSunProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam ); int WINAPI WinMain( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmline, int nShowCmd ) { WNDCLASS wc; wc.cbClsExtra = 0; wc.cbWndExtra = 0; wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH); wc.hCursor = LoadCursor(NULL,IDC_CROSS); wc.hIcon = LoadIcon(NULL,IDI_ERROR); wc.hInstance = hInstance; wc.lpfnWndProc = winSunProc; wc.lpszClassName = "SUNXIN"; wc.lpszMenuName = NULL; wc.style = CS_HREDRAW|CS_VREDRAW; RegisterClass(&wc); HWND hwnd; hwnd =CreateWindow("SUNXIN","WANGWENQUAN", WS_OVERLAPPED,0,0,800,600,NULL,NULL,hInstance,NULL); ShowWindow(hwnd,SW_SHOWNORMAL); UpdateWindow(hwnd); MSG msg; while(GetMessage(&msg,hwnd,0,0)) { TranslateMessage(&msg); DispatchMessage(&msg); } return msg.wParam; } LRESULT CALLBACK winSunProc( HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam ) { switch(uMsg) { case WM_CHAR: char szchar[20]; sprintf(szchar,"char code is%d",wParam); MessageBox(hwnd,szchar, "char",0); break; case WM_LBUTTONDOWN: MessageBox(hwnd,"
