Cannot Make Changes to Forms via Designer: "Error HRESULT E_FAIL has been returned from a call to a COM component."

I have a development stopping problem with Visual Studio.

I am making a program using C++ and the Windows Forms Application base.

I am very far into development and have had no problems. However, I have just encountered this today and can not get rid of it.

Upon making changes to my forms using the designer (any changes from new components to cosmetic changes to existing items) and compiling I am thrown this error in a message box:

"Error HRESULT E_FAIL has been returned from a call to a COM component."

The project is then not saved properly and my changes are not seen when the code is running. This is weird as my code compilies without

an error (loads of warnings, but I didn't think that these would have an effect, tell me if they might).

I need this problem fixed ASAP. It is really serious. Can somebody please help?

Hi m1ket,

As you said, the project is not saved properly. It might be crashed. You need to find which part might crash the project. Since I know little about your application, and I can't simply make a repro on my side, I can't infer which part might be the cause.

If it will cost little time to create a new form, and copy and paste the code to the new form, it would be better.

If you have any concerns, please feel free to let me know.

Best regards,
Bruce Zhou

Hello,

I am getting precisely the same error. The same message when I try to save from Designer in VC++ express.

I've been working on my project for some time now and I cannot just make a new form and project.

I really need to resolve this as it is stopping development for me, too.

I might note that I had to declare some of my GUI controls as static in order to be able to access them properly from static functions i.e. timer functions.
Maybe this is the cause of the problem??

Any help appreciated.
Thanks.
