Dialog Boxes and Sliders

for some reason i cant open a dialog box when i have two slide bars (sliders) in them. if i take them out, the dialog opens just fine but when they are in the DialogBox command returns -1. the code in my rsrc.rc file is as follows

Code:

CONTROL         "Slider1",IDD_SLIDER_MUSIC,"msctls_trackbar32",
                    TBS_AUTOTICKS | TBS_VERT | TBS_BOTH,215,23,29,81
CONTROL         "Slider2",IDD_SLIDER_CLUE,"msctls_trackbar32",
                    TBS_AUTOTICKS | TBS_VERT | TBS_BOTH,245,23,29,81

and in my resource.h i have numbers set up as follows

Code:

#define IDD_SLIDER_CLUE   204
#define IDD_SLIDER_MUSIC  205

other than that, i just use a normal DialogBox command to call the dialog and it will work if i take them out. as far as sliders go, i know that the limits have to be set and what not but where in a dialog would i set them, my dialog box function is as follows

Code:

LRESULT CALLBACK ConfigDlgProc(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{	
	switch (message)
	{
		case WM_INITDIALOG:
				return TRUE;
		case WM_COMMAND:
		{
		    if (LOWORD(wParam) == IDD_BUTTON_OK) 
			{
				EndDialog(hDlg, LOWORD(wParam));
				return TRUE;
			}
			break;
		}
		case WM_DESTROY:
		case WM_CLOSE:
			{
				EndDialog(hDlg, LOWORD(wParam));
				return TRUE;
			}
	}
    return FALSE;
}

what do i do to fix this?

If the resource ID numbers do not confilct with any others then have you used

InitCommonControls();

or

InitCommonControlsEx();

do i have to link any special libraries to use this? and should i initialize this before i call the dialog box or should it be in hte dialog box?

and i am using the win32 api for this, not mfc

ok, i added comctl32.lib in my project link area and now i am set
