模拟对Systreeview32内节点的单击

我只会c++语言。

如图，这个控件是Systreeview32。我需要单击“当日委托”这个按钮。
mouse_event的方法我已经实现了，但是有缺陷，不想用。
参照这篇模拟双击的方法

我写了代码如下。简单起见，我要点击“卖出”按钮



HWND hTree = HWND(0x60842);//systreeview32的hwnd，直接从spy++获得，暂且写死

HTREEITEM hItemRoot = TreeView_GetRoot(hTree);

HTREEITEM hItem = TreeView_GetNextSibling(hTree, hItemRoot);//这是卖出图标的hitem

::SendMessage(hTree, TVM_SELECTITEM, TVGN_CARET, (LPARAM)hItem);//这时候“卖出”图标会变成蓝色，表示被选中

DWORD pid = 0;

GetWindowThreadProcessId(hTree, &pid);

HANDLE hProcess = OpenProcess(PROCESS_ALL_ACCESS, true, pid);



RECT *prect = (RECT*)VirtualAllocEx(hProcess, NULL, sizeof(RECT), MEM_COMMIT, PAGE_READWRITE);

RECT rect = { 0 };

unsigned long n = 0;

*(HTREEITEM*)&rect = hItem;

WriteProcessMemory(hProcess, prect, &rect, sizeof(RECT), NULL);

::SendMessage(hTree, TVM_GETITEMRECT, (WPARAM)TRUE/*FALSE*/, (LPARAM)prect);

ReadProcessMemory(hProcess, prect, &rect, sizeof(RECT), &n);



POINT pt = { 0 };

pt.x = rect.left + (rect.right - rect.left) / 2;

pt.y = rect.top + (rect.bottom - rect.top) / 2;



NMHDR nm;

nm.hwndFrom = hTree;

nm.idFrom = GetDlgCtrlID(hTree);//这个在spy++里核实，control id确实是这个数

nm.code = NM_CLICK;

HWND hParent = GetParent(hTree);



::PostMessage(hTree, WM_LBUTTONDOWN, MK_LBUTTON, MAKELPARAM((WORD)pt.x, (WORD)pt.y));

SendMessage(hParent, WM_NOTIFY, nm.idFrom, (LPARAM)&nm);

::SendMessage(hTree, WM_LBUTTONUP, MK_LBUTTON, MAKELPARAM((WORD)pt.x, (WORD)pt.y));

//释放内存

CloseHandle(hProcess);

VirtualFreeEx(hProcess, prect, 0, MEM_RELEASE);
