    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();
