问题描述

跨进程获取 Treeview的Checkbox

我已经用读内存的方法实现遍历Treeview获取到文本并点击了，但是要获取到是否有勾选，一直失败，求教具体方法
我是填充结构体，发送?TVM_GETITEMA消息的

解决方案

如何获取别的进程的TreeView控件的内容
如何获取别的进程的TreeView控件的内容
获取其它进程中TreeView控件的内容

解决方案二：

TVM_GETITEMSTATE
用这个消息

试了下还是一回效果都没有
Public Function GetItemCheckState(ByVal hTree As Long) As BOOL
Dim vProcessId As Long, vProcess As Long, vPointer As Long, vItemCount As Long, vTreeItem As Long
Dim i As Long, Result As Long, Bytes As Long, vItem As TVITEM, tmpItem As TVITEM

Call GetWindowThreadProcessId(hTree, vProcessId)
vProcess = OpenProcess(PROCESS_VM_OPERATION Or PROCESS_VM_READ Or PROCESS_VM_WRITE, False, vProcessId)  '打开进程
vPointer = VirtualAllocEx(vProcess, 0&, 16, MEM_RESERVE Or MEM_COMMIT, PAGE_READWRITE)      '申请内存空间

vItemCount = TreeView_GetCount(hTree)  '获取Treeview Item的总数量
vTreeItem = TreeView_GetRoot(hTree)     '获取第一个 Item 句柄
For i = 0 To vItemCount - 1
    With vItem   '填充结构
        .mask = TVIF_STATE
        .HItem = vTreeItem
        .State = vPointer
        .stateMask = TVIS_STATEIMAGEMASK
    End With

    Call WriteProcessMemory(vProcess, ByVal vPointer, vItem, LenB(vItem), 0&) '将填充好的结构写入内存

    Result = SendMessageW(hTree, TVM_GETITEMSTATE, True, ByVal vPointer)    '发送消息让目标进程将 消息内容写入申请好的内存空间

    Call ReadProcessMemory(vProcess, ByVal vPointer, vItem.State, 4, 0&)    '读取内存

    With vItem
        Debug.Print .State, (CBool(Integer_Rotate_Right(.State, 12) - 1))
    End With

    ' TreeView_EnsureVisible hTree, vTreeItem   '保证项目显示
    vTreeItem = TreeNodeGetNext(hTree, vTreeItem)  '获取下一个项目
Next
Call VirtualFreeEx(vProcess, vPointer, 0, MEM_RELEASE)
Call CloseHandle(vProcess)

End Function
