check which .net framework u need

that will remove them from the view of course, but will keep them in memory.
he shouldnt use that if he wants to remove them for good.

thanks, but if u will not include not A nor B, how will the classes know each other exist?
i tried removing the includes - didnt work.

Hey, first of all, thanks for the comment! i will explain fully:

We have an engine, which is c++ written.
Somewhere along the execution, we call a user exit (which can be written in C++, perl, and batch).
i want to add implementation for .NET user exit - which means, the end user will write his user exit with C# (important to mention, that there's always a parameter when the user exit starts, an object that can be manipulated by the user. (like obj->SetInternalFlag(), or obj->WriteToLog(...))

so thats why, i need my c++ to call a user written C# DLL, and pass the c++ object where the user, inside C#, can call methods on,
then after the DLL is called (and i need a return code from his DLL - means, he should write a function that returns bool), i need to continue execution.

General user exit method looks like that, for example:
bool DoUserExitPostOperation(PostOperationObject obj);

For your second part,
i did consider to use c++/CLI (thats what i posted in my question), I can touch the engine, but at some point i need to call that C# dll, which is problematic to me.
anxiously waiting for your answer :)

Again, the return value and the GetLastError returns the same values, when the channel is up and working, and when i reopened mstsc while server is up (and data is not received anymore by either side)

so i cant use it

Its not what i've asked...
even if the channel is not active (i guess so atleast), i get no error when i send at the client side, and read at the server side.
the data just wont transmit (again, after closing the mstsc window).

i need to find out how to understand at the server that the client closed the window (if i'd get errors, it would be good, but thats not the case

The GetLastError() was actually for debug cases, it will go away.

And which code should i add?
i get the same results when the channel is active, and no data was sent yet,
and when the virtual channel is closed, and i reopen mstsc (The client does issue a connect, with no errors), but the server's channel is already gone.
same pBytesRead=0, and no error returns.

I just want somehow to understand that the client disconnected, or even better, connected, to issue an open call.
is that possible?

thanks :)

nope, just browsing the site, and to call a method that returns the html
The problem is, that i need to start that server proccess upon request,
and the port is configured by runtime,
so is it best practice to use a regular configuration, and maybe change the ports at runtime? is it even possibe?

(to clarify, if i use configuration at port 8080, next time i'll use another port, and even another URL, and i want the server to start up dynamiclly and listen to browser + regular WCF calls)

Thanks!

similar idea, but if there's no better solution i'll take that.
thanks!

no.. it inits everything to 0... not 0,1,2,3.. etc

no, you don't know the length of the array, u are getting that as a parameter.
means, what u have in ur hand is
int[] array = new int[n]

now, initialize it without a loop

nope, because u dont know whats the number of n, its variant.
if it would be constant then this initiazlization would be ok.

i got a tip to think more object oriented style.

hey, i tried your second solution (which is the best 4 me)

UPDATE tblTest
SET f1 = @f1,
CASE @f2 WHEN IS NOT NULL
THEN f2 = @f2 END,
f3 = @f3

when the table has f1, f2, f3 as fields.

it gives me:

Msg 156, Level 15, State 1, Procedure ariel, Line 20
Incorrect syntax near the keyword 'CASE'.


anyway, this worked for me:
UPDATE tblTest
set f2 =
case when (@f2 is not NULL) then @f2
else f2
END
where f1 = 1;

but isnt that an issue? because, if the value is null, it will update the last value (though i dont want it to do so)

obvious.
so thats way i asked, is there any best practice to do a generic update stored proc?
something like
update X
set
A = @a if @a != null
B = @b if @b != null

the only thing i could think of, is to select the previous values, and use a case in every set update.
