Does C# use COM/DCOM "under the hood" ?


I'd like to know if C# object system is based on COM/DCOM, or is it a

separate; CLR objects are managed, garbage-collected, etc; COM is
reference counted. Most CLR languauges can invoke COM via interop, and
likewise CLR objects can be exposed as COM servers through the reverse
process (see: "tlbimp" and "tlbexp"), but they are fundamentally very

Is there any case you can imagine that A97 would NOT display the Unhide option under the Window menu after running this line... Me.Visible = False Yes, its happening to me. The Unhide choice is grayed out after running this line on a form that was opened with the acDialog parm. Guys, this wierd stuff I'm encountering, could some hardware issue be responsible or would a viral element be more likely at fault?

Hello, I have a table named "USER" under MySQL database. When I am trying to move tables from MySQL to PostgreSQL, I found that I could not create a table namely "USER". I guess "USER" is a key string used by PostgreSQL system so that we could not create a table named "USER". Is that true? Thanks a lot, Emi Lu

Hi, hope I'm posting to the right forum. I'm using C# under .NET 1.1, Windows XP SP2 I have a form and I've overridden WndProc to print to a text box whenever it receives the WM_NCMOUSELEAVE message. Under "Windows XP Style", I get these messages fine (when the mouse moves off the title bar or form borders). Under "Windows Classic Style", I don't get the message at all! Has anyone seen this?

I suspect that this is a common problem (and so with a known solution/work-around), but my attempts to find it have failed. I have a float (a table of content box) on the left of a page.

I can force specific headers to have sufficiently large left...
