can't create as a child window

Hi,

I'm using ChartFX Client Server DLL version. I created chartfx window using

code as follows:

if

(SUCCEEDED(CoGetClassObject(__uuidof(ChartFX),CLSCTX_INPROC_SERVER,NULL,IID_

IClassFactory2,(LPVOID FAR *) &pFactory2)))

if

(FAILED(pFactory2->CreateInstanceLic(NULL,NULL,__uuidof(IChartFX),g_sLicense

String,(LPVOID FAR *) &m_pChartFX)))

return 0;

pFactory2->Release();

}

m_pChartFX->CreateWnd(NULL,IDC_CHARTFX,200,200,500,500,WS_OVERLAPPEDWINDOW

| WS_VISIBLE );

It works fine. But when I tried to create the chartfx as a child window

(using WS_CHILD | WS_VISIBLE), I got runtime error. I can't figure out why.

Any help will be appreciated.

With a valid parent window handle, the chartfx child window can be created.

Although using WS_OVERLAPPEDWINDOW| WS_CHILD, the chartfx child window does

not have a title and is not moveable. Don't know why.

Any idea about the problem?

Thanks. I have it as overlapped window. When I minimize this window, its

minimized icon goes to the bottom of the screen rather than the bottom of

the application main window. Is there anyway I can set this overlapped

chartfx window so that this winodw won't go outside of the application main

window?

Any help will be appreciated.

The only way is to create an MDI child window. The chart itself can not be

an MDI child window so you will have to create a "container" for the chart

that is the MDI child window and the chart is simply a child of that window.

Confusing ? I know ! But I hope you understand.

MDI is supported in MFC. You can check MSDN for more Info on MDI apps. Once

you figure out how to create an MDI child, its only a matter of creating the

chart inside of it as a child and resize the chart every time the MDI child

is resized.

Thanks a lot, I got the idea.

Unfortunately, I can't use MDI child window in my case.
