如何双击外部程序(另外一个进程)中的TREEVIEW节点

[faunaq]

如何实现双击外部程序中的Treeview 节点？？

我已经成功实现遍历和查找到目标节点，并选中该节点，但无法双击它。
发送sendmessage(treeviewHWD,WM_LBUTTONDBLCLK,MK_LBUTTON,0); 是无效的。

请大侠们给帮帮忙！

现在主要就是不懂怎么取外部程序内treeview 节点的区域坐标。

我在网上找到一个VC的。但是我对VC不太熟悉。有人能帮忙翻译成DELPHI的吗？


代码如下：

HTREEITEM Child61 = TreeView_GetChild(htree, Child6); //(火拼麻将)


BOOL bSel=(BOOL)::SendMessage(htree, TVM_SELECTITEM, TVGN_CARET, (LPARAM)Child61);
TreeView_EnsureVisible(htree, Child61);

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 = Child61;
WriteProcessMemory(hProcess, prect, &rect, sizeof(RECT), NULL);
::SendMessage(htree, TVM_GETITEMRECT, (WPARAM)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;

::ClientToScreen(htree,&pt);

//鼠标事件
SetCursorPos(pt.x, pt.y);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0,0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0,0);
mouse_event(MOUSEEVENTF_LEFTDOWN, 0, 0, 0,0);
mouse_event(MOUSEEVENTF_LEFTUP, 0, 0, 0,0);

//释放内存
CloseHandle(hProcess);
VirtualFreeEx(hProcess, prect, 0, MEM_RELEASE);

等待高手回答

1、先取得坐标 SendMessage(tv.Handle, TVM_GETITEMRECT, True, rc) ,再将rc.top,rc.Left坐标经由 ClientToScreen转为屏幕坐标；

2、根据取得坐标
mouse_event (MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, rc.left, rc.top, 0, 0 )
mouse_event (MOUSEEVENTF_LEFTDOWN | MOUSEEVENTF_LEFTUP, rc.left, rc.top, 0, 0 )

不懂 ，帮你顶一顶。

发送的时候要带坐标吧。
lParam
The low-order word specifies the x-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.
The high-order word specifies the y-coordinate of the cursor. The coordinate is relative to the upper-left corner of the client area.
