Does C have Call-By-Reference for a function??
I think it doesn't. Am I right?

You are right: C function arguments are passed by value.
you mean "wrong"?
No, you are wrong. The normal reading is handled by "C function
arguments are passed by value". The off-beat reading is handled by
the fact that C does NOT have "Call-By-Reference".
A third possible reading is that you are asserting "C function
arguments are passed by wrong".
:-) (and you are wrong)

If I remember right, I didn't mean "wrong" -- but I could be
wrong, right?
Two wrongs don't make a right, but three lefts do.

I miss street grids! Where I currently live, three left turns often
get me on a dead-end street, and usually get me lost - they are seldom
the equivalent of a right turn.

where I live 3 rights re likely to make a left, but three lefts will, on
average, get you in trouble with the police twice...

Hello
I am using asynchronous delegates to make a call to a COM ActiveX object, but even though the call occurs on a separate thread, my UI is still blocking.
If i put the thread to sleep in my delegate call, the application is well behaved (no UI freeze), but the call to the com object causes the UI to lock up
Do I have to manage calls to an ActiveX object differently than using the BeginInvoke and a callback

Hey all,
I am automating a web page from Visual Foxpro. I can control all the

Hi all,
This really is quite an urgent matter.
I have a page with multiple, dynamically-loaded user controls and when a
user clicks on a button, the whole form is submitted. Now at this stage I
know I need to call a function that will save data but I'm not sure exactly
when to call this function.
I've tried two ways and both seem to have 'gotcha's':

Hi all,
Is it possible to have two connects in the same rexx script to
different DB's?
I have to get data form on DB (with specifics selects and filter out
some values with RExx) and save the results into another DB?
I know from Wscripts and MS-Sql that you can build just two objects
but I did not see something like that in REXX.
Thanks in advance for your help

I've used Java to do this using JIntegra, but the application I'm using

Any advice?

For most users, this new feature is actually very convenient. If you want to control the update process,...
