If you do the same but not on a User Control it fires the event back correctly. Any got any ideas? Kind Regards, Chris Bond |

I have been assuming (falsely I think) that the conecpt of processes was also ther in .NET. I came to this conclusion when I was looking at two insatnces of my IE6 that where looking at the same page. I saw the same information in those two browsers , and that info was coming fr... |

| Equivalent of ObjPtr()? (2 replies) |
| microsoft.public.dotnet.general |
| When I was a VB6.0 guy, I could use the "super secret" ObjPtr() function to get an ID that uniquely identified a COM object. This was helpful for debugging situations where I THOUGHT two variables referred to the same object instance, but actually didn't. Is there a .NET equivalent? I have a case where two variables are pointing to an object, and it should be the SAME object, but it ain't. Its two... |

| workaround for lack of typedef? (2 replies) |
| microsoft.public.dotnet.general |
| Is there any workaround for lack of typedef in C#. I'm wrapping some legacy C code, and I can treat all the pointers to my structures as "void *" (in the C api they have nice names type def'ed to void * to hide the details of the structs from the caller) but this creates a type safety and readability nightmare, which typedef would alleviate. Consider the following example: ////////////////////////... |
