WinApi-如何获取SHELLDLL_DefView [英] WinApi - How to obtain SHELLDLL_DefView

问题描述

我正在尝试获取SHELLDLL_DefView的句柄.

I am trying to obtain handle to SHELLDLL_DefView.

所以，我有这段代码.

HWND hProgman = FindWindow(L"Progman", NULL);
HWND hWnd = FindWindowEx(hProgman, 0, L"SHELLDLL_DefView", NULL);

Eveyrtihing工作正常，直到我在Windows桌面环境中将其更改为幻灯片放映.然后，当我使用Windows的spy ++层次结构进行搜索时，SHELLDLL_DefView会具有另一个父级.现在是#32769(Desktop)-> WorkerW-> SHELLDLL_DefView.所以我找不到.问题是，当我尝试

Eveyrtihing works OK, until I change in Windows desktop brackground to slideshow. Then when I search with spy++ hierarchy of the windows, than SHELLDLL_DefView has another parent. Now it is #32769 (Desktop) -> WorkerW -> SHELLDLL_DefView. So I can't find it. Problem is that when I try

HWND desktop = GetDesktopWindow();
HWND hWnd = FindWindowEx(desktop , 0, L"WorkerW", NULL);
HWND hWnd = FindWindowEx(hWnd, 0, L"SHELLDLL_DefView", NULL);

找不到SHELLDLL_DefView.是的.

Than SHELLDLL_DefView is not found. WorkerW yes.

有人可以帮忙吗?

推荐答案

我找到了答案.需要遍历所有WorkerW.

I found the answer. Need to iterate through all WorkerW.

HWND destop = GetDesktopWindow();
HWND hWorkerW = NULL;
HWND hShellViewWin = NULL;
do
{
    hWorkerW = FindWindowEx(destop, hWorkerW, L"WorkerW", NULL);
    hShellViewWin = FindWindowEx(hWorkerW, 0, L"SHELLDLL_DefView", 0);
} while (hShellViewWin == NULL && hWorkerW != NULL);
