【求助】我的第一个C++窗口程序
我第一次用C++调用Windows API 来写窗口,但是我很郁闷,,我这个怎么米有窗口啊,,,大哥大们给帮忙看下。谢谢![code]#include <windows.h>
#include <stdio.h>
LRESULT CALLBACK WinLogerPro(
HWND hKeyloger, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
);
int WINAPI WinMain(
HINSTANCE klg, // handle to current instance
HINSTANCE hPrevInstance, // handle to previous instance
LPSTR lpCmdLine, // command line
int nCmdShow // show state
)
{
WNDCLASS keyloger;
keyloger.style=CS_HREDRAW | CS_VREDRAW;
keyloger.lpfnWndProc=WinLogerPro;
keyloger.cbClsExtra=0;
keyloger.cbWndExtra=0;
keyloger.hInstance=klg;
keyloger.hIcon=LoadIcon(NULL,IDI_ERROR);
keyloger.hCursor=LoadCursor(NULL,IDC_CROSS);
keyloger.hbrBackground=(HBRUSH)GetStockObject(WHITE_BRUSH);
keyloger.lpszMenuName=NULL;
keyloger.lpszClassName="keyloger";
RegisterClass(&keyloger);
HWND hKeyloger;
hKeyloger=CreateWindow("keyloger","键盘记录",WS_OVERLAPPEDWINDOW,0,0,600,400,NULL,NULL,klg,NULL);
ShowWindow(hKeyloger,SW_SHOWNORMAL);
UpdateWindow(hKeyloger);
MSG msg;
while(GetMessage(&msg,NULL,0,0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
}
LRESULT CALLBACK WinLogerPro(
HWND hKeyloger, // handle to window
UINT uMsg, // message identifier
WPARAM wParam, // first message parameter
LPARAM lParam // second message parameter
)
{
switch (uMsg)
{
case WM_LBUTTONDOWN:
MessageBox(hKeyloger,"How do you do?","Hello",MB_YESNO);
}
return 0;
}[/code]
你可以看看这个
#include <windows.h>LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM) ;
int WINAPI WinMain (HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
static TCHAR szAppName[] = TEXT ("HelloWin") ;
HWND hwnd ;
MSG msg ;
WNDCLASwndclass ;
wndclass.style = CS_HREDRAW | CS_VREDRAW ;
wndclass.lpfnWndProc = WndProc ;
wndclass.cbClsExtra = 0 ;
wndclass.cbWndExtra = 0 ;
wndclass.hInstance = hInstance ;
wndclass.hIcon = LoadIcon (NULL, IDI_APPLICATION) ;
wndclass.hCursor = LoadCursor (NULL, IDC_ARROW) ;
wndclass.hbrBackground= (HBRUSH) GetStockObject (WHITE_BRUSH) ;
wndclass.lpszMenuNam = NULL ;
wndclass.lpszClassName= szAppName ;
if (!RegisterClass (&wndclass))
{
MessageBox ( NULL, TEXT ("This program requires Windows NT!"),
szAppName, MB_ICONERROR) ;
return 0 ;
}
hwnd = CreateWindow( szAppName, // window class name
TEXT ("The Hello Program"), // window caption
WS_OVERLAPPEDWINDOW, // window style
CW_USEDEFAULT,// initial x position
CW_USEDEFAULT,// initial y position
CW_USEDEFAULT,// initial x size
CW_USEDEFAULT,// initial y size
NULL, // parent window handle
NULL, // window menu handle
hInstance, // program instance handle
NULL) ; // creation parameters
ShowWindow (hwnd, iCmdShow) ;
UpdateWindow (hwnd) ;
while (GetMessage (&msg, NULL, 0, 0))
{
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
}
LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HDC hdc ;
PAINTSTRUCT ps ;
RECT rect ;
switch (message)
{
case WM_CREATE:
return 0 ;
case WM_PAINT:
hdc = BeginPaint (hwnd, &ps) ;
GetClientRect (hwnd, &rect) ;
DrawText (hdc, TEXT ("Hello, Windows 98!"), -1, &rect,
DT_SINGLELINE | DT_CENTER | DT_VCENTER) ;
EndPaint (hwnd, &ps) ;
return 0 ;
case WM_DESTROY:
PostQuitMessage (0) ;
return 0 ;
}
return DefWindowProc (hwnd, message, wParam, lParam) ;
} 没看出来有什么区别啊,大哥。。。我第一次的东西就这样傻在这里了。。。
你看看有这个吗?我没太仔细看
ShowWindow (hwnd, iCmdShow) ;UpdateWindow (hwnd) ; 有, ShowWindow(hKeyloger,SW_SHOWNORMAL);
UpdateWindow(hKeyloger); 大家给看看啊!!!第一次啊。。。谢谢了!! 大家谁要是想要百度知道分的 可以去这里
http://zhidao.baidu.com/question/51449631.html 好了解决了,在百度知道。 对了半天的程序..好像少了调用系统的程序..要不然程序什么都不能做..这个东西很少记得..都是改改..看来有时间还要好好弄弄了
