Problem solved. My bad.
I had set up all the sSkinProvider & sSkinManager properties but had not selected a SkinName.
I was just leaving it blank. This causes an exception. All is well now and projects & demo compile without errors.
I have a question about the demo & the TsStoredSkin class.
The v7.04 ASL demo has added XPMan since v6.61. XPMan wasn't made available until D7. So I commented it out. But I thought maybe I should include Mike Lischke's Theme Manager (standalone component) which is what we D5ers do in such cases. But Theme Manager caused an exception in the demo so I deleted it. It compiles fine without it and all the Alpha controls and standard controls are nicely skinned and look great to me. So what does the demo use XPMan for? Doesn't AlphaControls have built-in themes support?
And I guess Class TsStoredSkin no longer has the properties: GeneralData, Images and Patterns ?
Because when I re-compiled my projects with 7.04, I got the 'Propery does not exist' error.
And sListBox has replaced sAlphaListBox or it was renamed ?
Are there any other changes I need to know about?
