Hi guys...

Is it possible to change the font colour of the calendar events so that the text appears lighter if the label background colour is dark.

Ideally I'd like the foreground colour to change to a lighter colour if the background is too dark to support black text.

Thanks in advance

Hi Guys,

I've found out from another forum how to get the inverse color to enable contrast with darker backgrounds ... in VB it's done using the following code...

Function GetContrastColor(lngParamColor ) As Long

GetContrastColor = Not lngParamColor And &HFFFFFF

End Function

I now want to implement this but I can't get the BeforeDrawThemeObject event to trigger. I've set it to fire for all flags but it's not getting fired ...

I guess I need to use this event to change the text color to contrast whatever colour the Event background has been set to.

Any help will be greatly appreciated.

Thanks
