Scrollable subwindow

[mingis]

What Windows SDK calls should I look for - I want to make a subwindow control with scroll bars. That subwindow shoud contain edit controls, comboboxes etc. and be logically bigger than the control on the parrent window - scrollbars should be used to scroll to hidden parts of that window. Actually I want to make what a subform control in MS Access form is. Or may be MS Excel document in maximized state without possibility to minimize. I don't want MFC. Should I use MDI (multiple Document Interface) technique?

What is wrong with the call:

frame_control=CreateWindowEx(0, "MDICLIENT", "KpFrame",
                  WS_VISIBLE|WS_CHILD,
                  iPosX, iPosY, iWdtX, iWdtY, hParent, 0, 
                  GetModuleHandle(NULL), 0);

It returns a zero result. hParent is handle of existing window, coordinates are inside of that window.
Are here some additional style flags missing?

Thank you.

I got explanation of the error on executing of CreateWindowEx(0, "MDICLIENT", ...):
"This function is only valid in Win32 mode", error code 120 ERROR_CALL_NOT_IMPLEMENTED.
What could it mean? The application is created as simply Win32 project, it starts through WinMain().

Got something - pointer to CLIENTCREATESTRUCT as last parameter of CreateWindowEx(0, "MDICLIENT", ..., (LPVOID)&ccs) missed.
