We are using Xtreme SuitePro ActiveX Controls v16.2.3 in our application and noticed our app is consuming lots of GDI-handles (> 6000). Most of them are font handles. I created two VB6 test projects, which both add 500 Labels onto a form. Project 1 uses Codejock.Labels, project 2 VB.Labels.  As you can see, project 1 uses 900 font handles whereas project 2 uses only 4. Is this normal behaviour and if so, can we somehow share the font handles between controls?

That is a known issue and we're working on fixing it for the next update. Regards, Alexander

The issue has been fixed for version 18.0, all GDI handles get cached now, which means that in some scenarios where lots of controls of the same class are use the reduction should be drastic. Regards, Alexander
