cw 3d graph control displays "evaluation copy"

[dan cooper]

I have created an application in VB4 which uses the cw 3d graph control 3.5. Everything looks fine on the development computer, but when I install the application to the target PC the graph displays "Evaluation Copy". I have added the control to my project using Tools-Custom controls and I am not using the control in any strange or groundbreaking way. How do I stop this happening, and does the control stop working after a certain period of time if I leave it as an evaluation copy?

As with most purchased ActiveX controls, our ActiveX controls have licenses. These licenses are in the registry of a development machine and have to be embedded in an application or DLL that uses the controls in order to distribute them. I know that VB5 and above does this automatically for any control you are using (unless you create it programmatically, not on a form). It could be that VB4 is NOT embedding these licenses in the EXE you are building as it does in VB 5 and 6. I didn't use VB 4 so I'm not sure about this.

Regardless, the problem is that your EXE that you are distributing does not have the license information for the control in it. You have to figure out why. In VB5 and VB6, people run into this when they are creating controls programmatic
ally instead of putting them on forms, but it doesn't sound like you are doing that. Search your VB 4 help for ActiveX control licenses.
