求高手帮忙,取得光标当前位置的句柄?

[skype_2009]

while (1) 
	{ 
		Sleep(100); 
		POINT pt; GetCursorPos(&pt); 
		hWnd = ::WindowFromPoint(pt); 
		if (hWnd != NULL) 
		{  
			CString strItem = L"精ab瑞cd电脑汉字";
			char szItem[] = "精ab瑞cd电脑汉字";
			WCHAR wszItem[256];
			m_edtInput.SetFocus();

			memset(wszItem, 0, sizeof(wszItem));
			MultiByteToWideChar(CP_ACP, 0, szItem, strlen(szItem), wszItem, strlen(szItem));
			for (int i = 0; i < wcslen(wszItem); i ++)
			{
				::SendMessage(hWnd, WM_CHAR, wszItem[i], 1);
			}
			break;
		} 
		else 
			continue;
	}

为什么向光标当前位置发送wszItem,得不到呢?

用SetTimer()也是不行,是错在哪?

两API函数GetCursorPos和WindowFromPoint即可搞定～

也是用这个两个API,可是就是不行,hWnd也不为空呀,就是SendMessage不成功

[zhaodaich]

BOOL CMyDlg::PreTranslateMessage(MSG* pMsg)
{
if (pMsg->message == WM_KEYDOWN)
{
switch (pMsg->wParam)
{
case 'V':
if(::GetKeyState(VK_CONTROL) < 0)
{
CWnd* pChildWnd = GetFocus();
if(*pChildWnd == * GetDlgItem(IDC_CTRL1))
{
CString str;
pChildWnd->GetWindowText(str);
pChildWnd->SetWindowText(str+"hahaha");
}
}
return TRUE;

}
}

return CDialog::PreTranslateMessage(pMsg);
}

其中：
pChildWnd->SetWindowText(str+"hahaha");
中的"hahaha"可换成你的：m_sMessage

这样,只能传到IDC_CTRL1上,我想做的,是把光标题到哪,就送到哪上

用mouse hook
LRESULT CALLBACK MouseProc( int nCode,
WPARAM wParam,
LPARAM lParam
);
lParam
[in] Pointer to a MOUSEHOOKSTRUCT structure.

typedef struct {
POINT pt;
HWND hwnd;
UINT wHitTestCode;
ULONG_PTR dwExtraInfo;
} MOUSEHOOKSTRUCT, *PMOUSEHOOKSTRUCT;

可以给个例子吗?

ScreenToClient

[skype_2009]

OnTimer()消息的代码

POINT pt; 
	::GetCursorPos(&pt); 
	POINT ptScreen=pt; 
	m_hParent=GetDesktopWindow()->GetSafeHwnd(); 
	m_hChild=::ChildWindowFromPoint(m_hParent,pt); 
	pt=ptScreen; 
		::ScreenToClient(m_hChild,&pt); 
	while(m_hParent != m_hChild) 
	{ 
		m_hParent=m_hChild; 

		m_hChild=::ChildWindowFromPoint(m_hParent,pt); 
		pt=ptScreen; 
		::ScreenToClient(m_hChild,&pt); 
	}

然后得到句柄,发送信息也是不行的,这错在哪?

CString strItem = L"精ab瑞cd电脑汉字";
	char szItem[] = "精ab瑞cd电脑汉字";
	WCHAR wszItem[256];
	m_edtInput.SetFocus();

	memset(wszItem, 0, sizeof(wszItem));
	MultiByteToWideChar(CP_ACP, 0, szItem, strlen(szItem), wszItem, strlen(szItem));

	if(m_hChild != NULL)
	{
		for (int i = 0; i < wcslen(wszItem); i ++)
		{
			::SendMessage(m_hChild, WM_CHAR, wszItem[i], 1);
		}
	}

OnTimer()改为如下

POINT pnt;
	
	RECT rc;
	HWND DeskHwnd = ::GetDesktopWindow();    //取得桌面句柄
    HDC DeskDC = ::GetWindowDC(DeskHwnd);     //取得桌面设备场景
    
    int oldRop2 = SetROP2(DeskDC, R2_NOTXORPEN);
    ::GetCursorPos(&pnt);                //取得鼠标坐标
    HWND UnHwnd = ::WindowFromPoint(pnt) ;    //取得鼠标指针处窗口句柄
	
	g_hWnd=UnHwnd;
    HWND grayHwnd = ::GetWindow(g_hWnd, GW_CHILD);
	RECT tempRc;
	BOOL bFind=FALSE;
    while (grayHwnd)
	{
        ::GetWindowRect(grayHwnd, &tempRc);
		if(::PtInRect(&tempRc,pnt))
		{
			bFind = TRUE;
			break;
		}
        else
            grayHwnd = ::GetWindow(grayHwnd, GW_HWNDNEXT);
        
	}//while
    if(bFind == TRUE)
    {
		bFind= FALSE;
        g_hWnd = grayHwnd;
    }
	else
        ;//Wnd=UnHwnd
