Hi,
i.e. you can use:
NetWkstaUserGetInfo
or
NetWkstaUserEnum - it enumerates currently logged users

I have written a COM add-in for MS.Word in MFC. I can get the content of a document, and control ms.word's document successfully. However, I can't do functions as ms.Equation 3.0 does, such as adding a mathematical symbol. I don't know how to do that, how the ms.equation does as well as what ms.equation solves in detail. I'm in dark. Would you like to give me some advice, or point me some webpages. Thanks...

Thanks, but this does not work.
I using VC++ 2005.

well, the code
int j = object->value;
could lead an unexpected result. sometimes exceptions like AV(Access Violation) could be thrown out, but not always.

In general catch(...) is bad form. A general rule of exception handling is that you should only catch what you expect to be thrown.

Deleting an object doesn't invalidate the pointer to the object.
You need to do:
delete object;
object=null;
I'm not sure how to check if deleting of the object actually worked...anyone...anyone..

Thanks, but if i do this code. The program does bot call:
int j=object->value;
and the error does not occur.
Above is a simple example, my problem is very complicate and i can not set NULL to object.
Thanks again.

Maybe I'm misunderstanding your problem...
If you delete an object, you can no longer access that object.
I.e. if you do:
delete object;
You are not allowed to access any member of the object, since it is "gone" (i.e. object->value will return something you don't expect).
If you do:
delete object;
object=null;
And then try to access object->value, you will most likely get an access violation (which is correct).
This is correct:
[By correct, I mean the code works, but don't do it this way, since you know you just deleted the object.]
delete object;
object=null;
if (!object)
{
// the object is deleted, you can't access it
}
else
{
int j = object->value;
}
Does that make sense?

Yes, if i do that my problem will be fixed.
But this code is a simple problem. my problem complicate than that, and i don't permission to set object = NULL; i just have permission to access it and check it for existing or deleted.
So if you know how to check it for existing(not deleted) please give me that code.
try{}catch("what is here"){} or other way?
Thanks again.
