EnumWindows filter to only windows that show up on alt-tab

Hey People,

I've been working on an application that needs to create a list of all open windows.

So far I've got EnumWindows working with a callback, but I can't seem to filter all windows out that don't show up during alt-tabbing.

How would I filter those windows out ? Below are the checks I already enforced in my callback function.

Code:

---

        if(hWnd == NULL)
                return true;

        int titleLength = GetWindowTextLength(hWnd);
        if(0 == titleLength)
                return true;

        if( ( false == IsWindowVisible(hWnd) || false == IsIconic(hWnd) ) && false == IsWindow(hWnd))
                return true;

        if(GetParent(hWnd) != 0)
                return true;

        // Add it to the list here

---

So what would I need to add to filter it to windows only seeable on alt-tab ?

Thank you for your time, Xeross

Hello, xeross,

Did you found solution?
I use the next code to get a list of all opened windows. And it works fine for me.

Code:

---

static BOOL CALLBACK EnumWindowsCallback(IN HWND hWnd, IN LPARAM lParam)
{
    if (!IsWindowVisible(hWnd)) || GetWindow(hWnd, GW_OWNER) != NULL)
        return TRUE;

    TCHAR szText[256];
    DWORD cchText = GetWindowText(hWnd, szText, 256);

    if (cchText == 0)
        return TRUE;

  // there we have a "true" window

}

PS: one window is not wanted. "Program Manager" is a main window which contains a desktop. But this is not a serious problem, isn't it?

Thanks, I'll try it out.
