I can suggest two other ways :
1. Change TLabel.Tag to -98 and this control will not be changed by skin.
2. In the TsSkinProvider.OnSkinItem event add this line : if Item is TLabel then CanBeAdded := False;
1 ° It will only work if set in own project label.tag: = -98.
at runtime if you try label.tag: = -98 will not work
2 ° will only work in the main form.
If the Form is
in Available Forms.
in son form will not work
thanks anyway
