I would like to know how to find information(books, online documentation) on using ActiveXcontrols in PowerBuilder.
I find the best way to learn how to use a new ActiveX control is to first use it in Visual Basic 5. Then once I have the syntax right in VB, I port the code over to Powerbuilder. VB5 has a nice feature that allows you to call functions and alter properties on objects with VB giving you hints on all the available functions and arguments.
You can also use the Object browser that ships with PB6. The OLE tab has good support for showing you the controls and attributes of ActiveX controls.
