Can't add ocx into vb6 form

Hi all friends

I have problems trying to add an ocx component into a vb6 form, i can add it from menu Project --> Components, but when a i drop-drag from toolbox it gives me the next error message (in spanish but i'll translate it) :

The component MyOCX or one of its depending files it's not registered correctly: a file it's lacking or a file it's not valid


I've tried the next:

-Unregister/register the last download version from different paths
-Delete all NameOfOcx in regedit and after unregister/regiser the ocx.


Does someone have any idea what's happenign??

I'll appreciate your help.

Who created this OCX?

Dave,

Someone in the Company where i work (I'll investigate it althougt it's difficult to know)

Also i did:

-Uninstall/Install VB6
-Install VB6SP5
-Delete CLS-ID info in regedit generated in th e VB project file linked to the OCX by VB6


ThanX!

Have them create a setup.exe with their P&D Wizard and run it on the problematic machine.

It may be one of those OCX files that has an associated .Dll file (I've seen before), and that could be the file that it is missing.

To me, the best way to solve this issue is track down the person that wrote it. You said that it was someone in your company. If this is the case, then your company owns the source code to this OCX, and therefore, should have it available for you (or any other programmer in your company) to look at. Have you asked about this?

If it's included in the project, then the P&D Wizard will offer to include it with the setup.exe/cab file.

I thought the original problem was that he couldn't load it into a project. However, Dave, you bring up an interesting point which leads to a question.

quetzalcoatl: Does the problem you are having deal with loading this component into a new project? If so, are there existing projects in which it does load properly?

Er, when I say "included in a project," I do of course refer to the act of adding the reference through the IDE. DLL library refernces loosely in modules may not be included in the setup.exe/cab. I have never checked.

If you reference an external .Dll then said .Dll needs to be distributed with your project.

That may be but I was referring to the capabilities of the P&D Wizard to do your packaging for you.

As pointed out by Hack, you may need to take extra steps for "loosely" linked DLLs.

Hi again all friends

ThanX for all your posts,


Hack

It happens either in a new project or in a project which they gave to me, in that project is where i'm trying to load that OCX.


It is not a setup, it is a VB6 project which was given to me, so they told me install those DLL's in that folder and those OCX's in that folder and you will be able to use,debug the VB6 project, i've uninstalled/installed all those OCX's and DLL's but is the same thing, i'm trying to get the code of that OCX to see if it is referencing to some DLL, but it's a little difficult because it's a little old OCX and the author doesn´t work here anymore.



ThanX!

The MyOCX had to have come from a project. That is the project that needs to have a setup.exe/cab created. Only then will you be able to use it.

If the OCX is VB6 authored then make sure the colleague who compiled it had binary compatibility set to ON.

If he hasn't then you will have a nasty problem of 'interface forwarding' mainly because VB6 will try to fix your problem and fail miserably.

If this is the problem you will need to get some form of registry cleaner, and then reinstall the component using the methods described above.
