怎么获得系统新开一个窗口的通知，是用钩子吗？

[qsfsea]

我想拦截一个指定Caption的窗口

给个思路？

[zhucde]

OnTimer()中即可.

CWnd *pwnd=FindWindow(NULL,"caption");
if(pwnd)
{
//得知窗口已开
}

CBTProc
The CBTProc hook procedure is an application-defined or library-defined callback function used with the SetWindowsHookEx function. The system calls this function before activating, creating, destroying, minimizing, maximizing, moving, or sizing a window

这么多星星啊

[skymartin]

hHookCBTs = ::SetWindowsHookEx( WH_CBT, (HOOKPROC)CBT_Proc, hGameHook, 0 );

LRESULT __declspec(dllexport) __stdcall CALLBACK
CBT_Proc( int nCode, WPARAM wParam, LPARAM lParam )
{
AFX_MANAGE_STATE(AfxGetStaticModuleState());

if (nCode < 0)
return CallNextHookEx(hHookCBT, nCode, wParam, lParam);

switch (nCode)
{
case HCBT_CREATEWND:
break;
case HCBT_DESTROYWND:
break;
}
}

下面是关闭莫个特定标题的程序代码
void DestroyHelpWindow(void)
{
EnumWindows(DestroyHelpProc,NULL);
}

BOOL CALLBACK DestroyHelpProc(HWND hwndChild, LPARAM lParam)
{
char childText[30];
GetWindowText(hwndChild,childText,30);

char HelpTitle[MAX_LOADSTRING];
LoadString(hInst, IDS_Help_TITLE, HelpTitle,MAX_LOADSTRING);

if(
strcmp(childText,HelpTitle)==0
)
{
PostMessage(hwndChild,WM_SYSCOMMAND,SC_CLOSE,0);

return FALSE;
}

return TRUE;
}
