Thank you for your tip. However, when I register my assembly, I can see my object now but not all its methods and attributes, whereas they are public ... Have I missed something ?

I used a C++ client to call the .NET component. In C++ file, I added a preprocessor directive

#import "DotNetComponent.tlb"

to import the type library created for my .NET component. Check if you missed this step.

Thanks a lot!!! I wished I had read your blog sooner!!! You saved me after a 2 hours of not knowing what else to do!

Fantastic! You saved me after only 15 minutes of messing around on my own.

Thanks for this tip. It worked! :))

Thanks..... I have problem which is solved in second with your tip....otherwise I do not know how much time it is going to take

Hi
It was very Helpful. I think you work for Interop. I am developing application in VC++ calling C# DLL. Do you have some sample code of use for CComPtr.
Thanks in advance for your help.

Thanks! I tried every trick I've learned so far but it seems .net can surprise us over and over again.

BTW: There is an additional option that turn on and off the Assembly level ComVisible attribute. If you go to the Project properties and select the Application tab, there is a button labeled "Assembly Information...". If you click this button, a diaglog appears that allows you to basically edit the AssemblyInfo.cs file. Well, maybe not everything, but some of the default things anyway. For example, there is a checkbox labeled "Make assembly COM-Visible". Checking and/or unchecking this checkbox sets the [assembly: ComVisible(?)] property true or false (in replace of the question mark "?"). So, if you want all your stuff to be ComVisible(), then you can check this and on the Build tab check "Register for COM Interop".

Does the ComVisible attribute requirement essentially mean that none of the classes in the Framework itself are directly accessible from COM? Do I have to write my own wrapper to make them accessible or are some of them marked as ComVisible?

Thanks

i would like to know how to convert a com component to an assembly dll refrence i knew that i moght user ceself registration but i dont know how

Awesome! I had totally forgotten about the COM-visible. Thanks for being there

thanx for sharing, such a stupid thing ;-)!

Thanks man. It saved lot of my time.

Thanks Buddy, your posting really helped me save lot of time.

Yeah, a very handy tip i would say :)
Thanks pal.

Thanks for the post, this saved me after only 5 minutes of struggling.

I would like to add that for me in VS2005, I was building a class.  Rather than editing the assembly file, I perfromed the following steps:

From Project Properties window, choose the compile tab.  Tick the checkbox for "Register for COM Interop".  Hope this helps.
