I simply put code like:
In the refresh method of the form:
thisform.showallheaders.picture=IIF(thisform.lshowallheaders,"UP.BMP","DOWN.BMP")
thisform.showallheaders.tooltiptext=IIF(thisform.lshowallheaders,GetFldTxt("sysmsg","cMsg_HideHeaders"),GetFldTxt("sysmsg","cMsg_ShowHeaders"))

As long as UP and DONW .BMP files are included in the project it'll find them.


Another choice is to add the two picture to the form and make 1 invisble
at the appropriate time.

There is also an IMage List control your find on your system.
