如何在Visual c++中从窗口中获取控件列表

Question

如何从窗口获得控件列表，由"FindWindow"函数指定?例如，我有一个对记事本窗口的句柄

HWND Window = FindWindow(L"Notepad", L"dummy.txt - Notepad");

然后我可以通过

创建一个"编辑"控件的句柄

HWND WindowEX = FindWindowEx(Window, NULL, L"EDIT", NULL);

，但我怎么能得到控件的完整列表，并记录在数组中，例如?

我还是按老方法做的

array<HWND>^ childs = gcnew array<HWND>(1000);
array<String^>^ childsnames = gcnew array<String^>(1000);
int childcount = 0;
public:
    delegate bool EnumDelegate(HWND hWnd, int lParam);
public:
    [DllImport("user32.dll", EntryPoint = "EnumChildWindows", ExactSpelling = false, CharSet = CharSet::Unicode, SetLastError = true)]
    static bool EnumChildWindows(HWND hwndParent, EnumDelegate ^lpEnumCallbackFunction, int lParam);
bool enumchildproc(HWND hWnd, int lParam)
    {
        int nLength = GetWindowTextLength(hWnd);
        LPWSTR strbTitle = (LPWSTR)VirtualAlloc((LPVOID)NULL,
            (DWORD)(nLength + 1), MEM_COMMIT,
            PAGE_READWRITE);
        //GetWindowText(hWnd, strbTitle, 255);
        GetClassNameW(hWnd, strbTitle, 255);
        String ^strTitle = gcnew String(strbTitle);
        childs[childcount] = hWnd;
        childsnames[childcount] = strTitle;
        childcount++;
        return true;
    }
void refreshChilds(HWND Parent, ComboBox^ cb)
    {
        cb->Items->Clear();
        childcount = 0;
        int i = 0;
        Array::Clear(childs, 0, 1000);
        Array::Clear(childsnames, 0, 1000);
        EnumDelegate ^filter = gcnew EnumDelegate(this, &MyForm::enumchildproc);
        EnumChildWindows(Parent, filter, 0);
        for (i = 0; i < childcount; i++)
        {
            cb->Items->Add(childsnames[i]);
        }
    }

refreshchildren()函数将用孩子的类名填充组合框。
