I am trying to use a CFrameWnd in my code and I keep getting an assertion error when I try to ShowWindow(SW_SHOW);

CWnd * tempWnd = new CWnd(); //Create a new CWnd object
tempWnd->Attach(p_adsw_hwndAcad); //handle to the main window
CFPLvlLyrWnd *mWnd = (CFPLvlLyrWnd*)(RUNTIME_CLASS(CFPLvlLyrWnd))->CreateObject(); //CFPLvleLyrWnd is derived from CFrameWnd
RECT sizze = CFrameWnd::rectDefault;
DWORD dwStyle = WS_OVERLAPPEDWINDOW;
    //set up Window size
if (mWnd->Create(NULL, "Levels/Layers", dwStyle, sizze, tempWnd, MAKEINTRESOURCE(0) ))
{
        mWnd->m_parentWHandle = p_adsw_hwndAcad;
            tempWnd->BeginModalState();
    mWnd->ShowWindow(SW_SHOW);
}
else
{
    AfxMessageBox("LoadFrame failed!");
}
HWND tempHandle = tempWnd->Detach();

delete(tempWnd);

This will run in VS 6.0 but in VS 2005 I get an assertion error and the program crashes. What could be the problem?

mWnd->ShowWindow(SW_SHOW);

When it gets to this point, the assertion error appears. I stepped into the code for ShowWindow and when it calls the AfxGetThread() it returns a NULL then it gives the assertion error because the return should not be NULL.

Unfortunately I still haven't found a solution for this problem. I ended up just going back to using VS 6.0 to continue developing my software.

Cannot resize my IWebBrowser2 Web Browser Control

Johann Gerell21-May-08 5:31

I have a problem with my embedded web browser control (IWebBrowser2).

I try to resize it when it's host (which is a child of the main frame) gets WM_SIZING while the main frame is resized. I was under the apparently naîve impression that I could do this by calling put_Width and put_Height on the web browser in WM_SIZING.

Making these calls actually triggers the DWebBrowserEvents2 events DISPID_WINDOWSETHEIGHT and DISPID_WINDOWSETWIDTH, but the size of the web browser control remains unchanged.

Any guesses as to why this happen?

Is there some reason you are not using CHtmlView?

Yes. If possible, I'm not letting MFC within a mile of my codebase. But please let's not discuss that now... Cool | :cool:

Anyway, I'm now bypassing IWebBrowser2::put_Width/Height by moving the actual OLE object window, roughly like this (error checks omitted):

ATL::CComPtr<IOleWindow> oleWindow;
iOleObject_->QueryInterface(&oleWindow);

HWND hwndBrowser = NULL;
oleWindow->GetWindow(&hwndBrowser);

::MoveWindow(hwndBrowser, 0, 0, cx, cy, TRUE);

As an interesting addition, I noticed that IWebBrowser2::get_HWND gives NULL for the window, where I expected the same result as querying the IOleWindow interface. Confused | :confused:

Ah, I see, you believe there is something wrong with MFC but you are fine with writing COM code. Did you read your own post?

No. I'd avoid it if I could, but I'm not going to throw in MFC into my project just because I need HTML display functionality.

Yes. Multiple times. Since I'm not a native English speaker, I want to maximize the likelihood for anyone to understand what I mean. Why did you wonder that?

How to hide window when the app starts ?

I have an app with an icon on system tray. I want to hide the window (just
let the icon appear). I tried to use dlg->ShowWindow(SW_HIDE)instead of DoModal() but when the icon appears, it's useless (when we move the mouse to it, it disappears). Someone plz give me a solution, thanks Rose | [Rose]
