I've create a OCX (VB6) that itself registerd. ( Declare Function Regxxx Lib "xxx.OCX" Alias "DllRegisterServer" () As Long ). When i use it in a new project (NEWPRO also VB6) then is everything fine, but then when i change the OCX and compile it again NEWPRO can't load it anymore.

The problem you are experiencing sounds like a compatibility issue.
When you create an OCX, the system assigns a unique ID to the controls and classes that your component exposes. Your other program, that uses the control, looks at these ID's to make sure that it has the correct control.
Every time you recompile the OCX, new ID's are assigned, so that your program that tries to use it does not recognize it and thinks it's the wrong control.
To fix this, go to your peoject's properties. Select the Components tab. You will see a section entitled "Version Compatibility". You have to set it to "Binary Compatibility". This basically means that each time you compile, it will keep the same ID's.
Hope this helps.

Thanks a lot Shrog.
Futher I wanna say when you do this check the path from the OCX that displays into the textbox or you've got a error like me at the first time.
