minimize an Excel window using c++

I'm trying to minimize an Excel window using c++. but it doesn't work.

Code:

---


//Save the PID
HWND hWnd = FindWindowA(NULL, (LPCSTR)pXlApp); 
GetWindowThreadProcessId(hWnd, &proccesID);

// Make it visible
{
VARIANT x;
x.vt = VT_I4;
x.lVal = isVisible;
AutoWrap(DISPATCH_PROPERTYPUT, NULL, pXlApp, L"Visible", 1, x);
}

---

Here I tried this:

Code:

---


{
SetForegroundWindow((HWND)(((ULONG) hWnd) | 0x01) );
BringWindowToTop(hWnd);
ShowWindow(hWnd, SW_MINIMIZE);     
}

---

and this:

Code:

---


{
ShowWindow(hWnd, SW_MINIMIZE);     
}

---

amd i have also tried WINDOWPLACEMENT and other things, and anything works.

I checked the HWND is not null, but is not visible....

Code:

---


bool visible=IsWindowVisible(hWnd);

---

and visible=false, but the window is Visible (I see the Excel file)

Do you know why?

Could you help me?? Thank you

Probably, you got anoter window handle. Just use Spy++ to see if that's true.
And/or try this:

Code:

---

    HWND hWnd = ::FindWindow(_T("XLMAIN"), NULL);
    if(NULL != hWnd)
    {
        if(! ::IsIconic(hWnd))
        {
            ::ShowWindowAsync(hWnd, SW_MINIMIZE);
        }
    }

---

Also verify with Spy++ if the main window class name is "XLMAIN" or another one (may differ in other Excel version).

that works very good.
thank you very much!!
