我可以跨行程獲取listctrl的行數和列數，所有的內容。但是不能獲取標題欄的內容，有沒有高手知道？
下面的代碼可以獲取Listctrl的單元格內容，但是Header我照著寫，就是得不到.
WriteProcessMemory(hProcess, pHeaderItem, &HeaderItem, sizeof(HDITEM), NULL);
::SendMessage(pHeaderCtrl->GetSafeHwnd(), LVM_GETITEMTEXT, 0, (LPARAM)pHeaderItem);
ReadProcessMemory(hProcess, pItem, ItemBuf, 512, NULL);

你Debug下除錯一下看看，資料都分配空間了沒？呼叫上面的ReadxxxMemory得到的資料正確嗎？uj5u.com熱心網友回復：
BOOL GetItem( int nPos, HDITEM* pHeaderItem ) const;uj5u.com熱心網友回復：
有分配的。
pHeaderItem = (HDITEM*)VirtualAllocEx(hProcess, NULL, sizeof(HDITEM), MEM_COMMIT, PAGE_READWRITE);
pItem = (char*)VirtualAllocEx(hProcess, NULL, 512, MEM_COMMIT, PAGE_READWRITE);
if ((!pHeaderItem) || (!pItem))
{
::MessageBox(NULL, "無法分配記憶體!", "錯誤!", NULL);
}
for (i=0; i<nHeaderCount; i++)
{
HeaderItem.cchTextMax = 512;
HeaderItem.pszText = pItem;
WriteProcessMemory(hProcess, pHeaderItem, &HeaderItem, sizeof(HDITEM), NULL);
::SendMessage(pHeaderCtrl->GetSafeHwnd(), LVM_GETITEMTEXT, 0, (LPARAM)pHeaderItem);
ReadProcessMemory(hProcess, pItem, ItemBuf, 512, NULL);
}
//釋放記憶體
CloseHandle(hProcess);
VirtualFreeEx(hProcess, pHeaderItem, 0, MEM_RELEASE);
VirtualFreeEx(hProcess, pItem, 0, MEM_RELEASE);

你好，這個只能用于自己的程式，不能跨行程讀別人的對話框
uj5u.com熱心網友回復：
ListCtrl 標題 可能先要 獲取標題欄視窗句柄 ListView_GetHeader然后 用 HDM_GETITEM 訊息讀取 內容

謝謝樓上的，不能跨行程uj5u.com熱心網友回復：

}
從 “HWND hWnd=::WindowFromPoint(point);” 得到 HeaderCtrl 的 hWnd ！
