FIX: FFCs -_therm.vxc Classes Have Color Problems with Bars (221636)

SYMPTOMS

The classes from the _therm.vcx FoxPro Foundation Class appear with the wrong colors. The progress bar indicator should use the color of selected text, and the back color should inherit the back color of the form. However, the progress bar itself appears dark gray and the back color is light gray.

RESOLUTION

There are two resolutions to this problem:

Uncomment the Init code of the progress bar found in the example below. This code uses the GetSysColor API and the FillColor property of the _therm.vcx to assign the proper colors.
Upgrade to Visual Studio 6.0 Service Pack 3.

STATUS

Steps to Reproduce Behavior

Create a program file containing the following code:

PUBLIC oform1
SET CLASSLIB TO HOME(1)+"ffc\_therm.vcx" ADDITIVE
oform1=NEWOBJECT("form1")
oform1.SHOW
RETURN

DEFINE CLASS form1 AS FORM

	CAPTION = "Form1"
	NAME = "Form1"
	BACKCOLOR = RGB(136,192,184)

	ADD OBJECT _progressbar1 AS _progressbar WITH ;
		TOP = 47, ;
		LEFT = 24, ;
		BORDERWIDTH = 0

	ADD OBJECT timer1 AS TIMER WITH ;
		TOP = 180, ;
		LEFT = 72, ;
		HEIGHT = 23, ;
		WIDTH = 23, ;
		INTERVAL = 30, ;
		NAME = "Timer1"

*!*		PROCEDURE _progressbar1.INIT
*!*		#DEFINE COLOR_HIGHLIGHT 	13
*!*		DECLARE INTEGER GetSysColor IN win32api INTEGER
*!*		THIS.shpThermBar.FILLCOLOR = GetSysColor(COLOR_HIGHLIGHT)
*!*		THIS.shape5.FILLCOLOR = THIS.PARENT.BACKCOLOR
*!*	ENDPROC

	PROCEDURE timer1.TIMER
	IF THISFORM._progressbar1.ipercentage = 100
		THISFORM.RELEASE()
	ENDIF
	THISFORM._progressbar1.UPDATE(1+THISFORM._progressbar1.ipercentage)
	THISFORM.REFRESH
ENDPROC

ENDDEFINE

Run the program. Notice that the progress bar indicator is dark gray and the progress bar back color is light gray. To see the workaround, uncomment the Init code in the progress bar.
