I have an ActiveX component that I wrote in VB to access a BarCode Label product. When I run the following code it registers on some machines, but others I get an error that says component can not self register. Any ideas:

if RegisterControl(stringVar) then
msgInfo("Congrats", "Control Registered")
else
errorShow()
endIF

This is for a Paradox 9 app with the latest patch on Win 9x machines.

Adding to this thread for lurkers...

ObjectPAL's registerControl() and unregisterContro() only work if the ActiveX control supports self-registering.

Self-Registering means that the control enables ObjectPAL to register and unregister the control at run-time. In other words, you register the control with ObjectPAL if the ActiveX is enabled for self-registering. You don't have to work with the Registry. Although you don't need to know this from ObjectPAL, a self-registering ActiveX control implements and exports two functions for registering and unregistering itself: DllRegisterServer() and DllUnregisterServer().
