[Winanjaya]

Dear The Expert,

I am trying to use vb6's mscomm control (mscomm32.ocx) on vb.net .. when drag to form, I got the following error message:
"You do not have a license to use this ActiveX control" ..

am I missing something?

Please advise . thanks a lot in advance

Yes you are.

The easiest thing to do would be to install VB6 on your .net machine.

my vb.net application is commercial application, does it also will happen on target PC? , it's not funny if it also required to install vb6 on target PC.. any idea ?

Thanks

You do not need to install VB 6 to customer PC. When you use any com object , VB.NET adds the object to your project and also install to target machine.

To use the object , you need register VB 6 controls to your machine. You will find a registry file in your VB.NET CD1
(folder name is "...:\Extras\VB6 Controls\vb6controls.reg" )
Double click the file and add it to your registry.

That's all

Good Luck

I am getting this error on my target machine. What could possibly be wrong if VB.NET adds the object to your project and also install to target machine? Apparently, it did not.

Thanks!

Will this help :

any OCX needs to be registered on the machine it is installed to (this is one of the major downfalls of COM that no longer exists in .NET)

problem is if you use any COM stuff, even in a .NET app, it still needs to be registered using regsvr32

or use : Regasm.exe

which use COMs , if I remember correctly ... . If it's the tool that make callable wrapper for the COM and needs no registeration later . Correct me if I'm wrong .

ok I will

I think what it actually is, is the opposite. It wraps a .net assembly so it can be called from COM

Then I must have confused it with another tool . I think I was talking about Tlbimp.exe , if that helps .

Thanks...but how do I do this on the target machine?

Will the below work for the problem we are talking about for a target machine or is this only good for the design time error?

Well....running the VB6CONTROLS.REG file on the target seemed to fix the problem. It may not be the final solution, but worked for now.
