Probably need to include a value for the hMenu parameter - usually a resource id for the child window, so something other than 0.

IDC_TOOLBOX equ 1000

    You classes were registered and changing hMenu to other than zero doent seem to work. the multiwin example from MASM32 sdk has a menu attached to the window. i guess i'll try that. thanks guys

The problem is that instead name class you write the class. Change to:

invoke  CreateWindowEx,0,addr ToolBoxClassName ,addr ToolWindowName,\
                        WS_CHILD+WS_CAPTION,0,0,100,400,hwnd,0,hInstance,0
        mov     hToolWindow,eax

    yup. Ty. That was the problem. ty for help
