    CreateWindow, primary expression expected

    I must be blind and not see something, or I've stared at this for too long... or both. But can someone help me see what is going on here? I successfully set up the tabs in another program, and am trying to do the same to my current project. The only difference between the two projects is this one is on a dialog and the previous working one was a main WndProc() window. Here is the section that is giving me the error.
    Code:
            case WM_INITDIALOG:
            {
                RECT rect;
                tablehwnd = onehwnd;
    
                GetClientRect(tablehwnd, &rect);
                InitCommonControls();
                
                //Create tabbed window
                hwndTab = CreateWindow(WC_TABCONTROL,"",WS_CHILD|WS_VISIBLE, //<< line that is having trouble
                      0,0,rect.right,rect.bottom,tablehwnd,(HMENU)TCITEM_HANDLE,
                      (HINSTANCE)GetWindowLong(tablehwnd,GWL_HINSTANCE),NULL);
    
                //Set up tabs
                tcitem.mask = TCIF_TEXT;
    
                //Create tabs
                tcitem.pszText = "Tab 1";
                int tabctrlone = TabCtrl_InsertItem(hwndTab, 0, &tcitem);
                tcitem.pszText = "Tab 2";
                int tabctrltwo = TabCtrl_InsertItem(hwndTab, 1, &tcitem);
    
                //Set tab index to 0, and show window for tab 0
                TabCtrl_SetCurSel(hwndTab,0);
                ShowWindow(hwndCalc,SW_SHOW);
    
                //Change tab font
                SendMessage (hwndTab,WM_SETFONT,(WPARAM) GetStockObject(DEFAULT_GUI_FONT), 0);
            }
            break;
    Code:
    C:\Beta Studios\CP Full\main.h||In function `BOOL MathTableProc(HWND__*, UINT, WPARAM, LPARAM)':|
    C:\Beta Studios\CP Full\main.h|4519|error: expected primary-expression before ')' token|
    ||=== Build finished: 1 errors, 1 warnings ===|
    EDIT: Fixed it! I don't exactly know why, but I changed the (HMENU)TCITEM_HANDLE to NULL and it worked. If someone wants to explain that to me that'd be awesome, otherwise it's no big deal.

    What was TCITEM_HANDLE?

    As you used the child style, the CreateWindow() is expecting an ID number for the control (not a handle to a menu).

    Resource ID numbers are limited to 0xdfff (57,343).

    Exceeding this number may have caused the issue?

    EDIT: Using zero for the ID number may not be a good idea also....

    The TCITEM_HANDLE was set as
    Code:
    #define TCITEM_HANDLE 6
    So it's possible the compiler did not like the value I defined it as. But yet, I have other handles defined as 1 to 14, although they are used in the resource file, and not a handle in a CreateWindow() function. But, removing it and placing NULL there did not make anything in other areas any more difficult. I just use the hwndTab handle when I want to use that window. Actually, the only time I use hwndTab is when I make a static window a child of hwndTab. Thanks for the help clearing that up, though!

    You have to use NULL for the hMenu value ...
