HELP!!!! Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

Hi Experts.... im in a spot of bother and need some help because I am most certainly bambooozled...

I have recently had to have my works laptop re-imaged due to various problems and since having it back I have had VS 2008 reinstalled and have re-downloaded my applications that I support and devlop.

One of the applications I work on, still works perfectly fine on one machine, but when I look to continue to develop this in VS2008 i get the following error.

Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))

Previously it did say that it could not find a dll which I have readded as a reference in the application, and that error cleared but I cant seem to shift this on...

The only thing I can think of that is different is the lack of VS2005 which I am currently downloading from MSDN (slowly) to see if this will help.... but as a sceptic I dont think this will work.

Any ideas??

umeli

Do you use any 3rd party controls in your application? maybe they are not correctly installed or registered on your system.

>Previously it did say that it could not find a dll which I have readded as a reference in the application, and that error cleared

What DLL was that? Is it a COM component? Did you register it as well?

SimonPrice33

ASKER

the dll that it could not find was AxInterop.MSWinsockLib.dll.

SimonPrice33

ASKER

and no... we dont use any third party controls

Nasir Razzaq

By 3rd party, I meant any library outside .NET and that happens to be winsocks library.

SimonPrice33

ASKER

oh, quite probably as this has recently been converted from VB6

SimonPrice33

ASKER

having chance to look more into this today its a COM object thats not registering... and I cant get the bloody thing to register properly...

any ideas?

Nasir Razzaq

What did you try? regsvr32?

SimonPrice33

ASKER

I have tried that, but it doesnt know the insertion point...

it stil works on one pc which is good.... and i have re-referenced it in the project, but its still unregistered....

any suggestions?

Nasir Razzaq

hmm. If its a COM component then it should register fine. Cant think of anything else.

SimonPrice33

ASKER

me either... :(

David Gerler

Let's not give up there... I have the same problem almost exactly. My ex-vb6 application was looking for: AxInterop.MSComctlLib and AxInterop.MSComDlg.

I added them as a reference out of the obj folder. It allowed it to compile now, but throws: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)) at runtime.

dgerler, is this an issue you have now or something you previously experienced?

im reimaging my laptop again this week and starting again incase there is something different to the last time...

I think i am going to reinstate an old PC and pull it in through VS 2005, see if that works, upgrade it again to 2008 and then copy over my new files... its a rediculous way round but doesnt hurt to try it...

plus i have nothing better to do in the office this week :)

bloody computers!!!

David Gerler

That's all good, but what about when you deplay it to another computer for use? I found this website http://www.vbtonet.com it cross refences vb6 to .net

SimonPrice33

ASKER

works fine... please tell me why you object to a solution to my problem??

David Gerler

I wasn't "Objecting". Sorry that I tried to assist. Certainly close the question and keep the points. I don't usually post solutions, but thought I'd try to help you out.

I just know when I tried to deploy my app where I was having this problem, it didn't work. In your case, if you use it to another computer, you have to install vb6 again.

Nasir Razzaq

> please tell me why you object

There is a bug in EE currently which sends "Objection Posted" emails even when just a comment has been posted after a close request.
