I'm not really sure what you are asking? Since I don't know what your post looked like before you modified it, I don't know what you changed. 
Are you wanting to know how to disable more than one button via a single function call?

And my client never make any request to the server. all the updates avilalable will be throughed by server.
just like push server but need to implement in c++.
is there any technology which can i implement ?

How are the clients and server connected?

my gut feeling say (i might be wrong?) Most probably you server might be web server!, you could put HTTP request to retieve data from the server!

Hello everyone,
Both stdcall and cdecl calling convention could support variable input parameters? Is that correct?
(I think stdcall is using RET N and cdecl is using ESP - N, so both are capable to handle variable number of input parameter, like printf?)
BTW: I have this question because I have something in mind that only one of them supports variable number of parameters, but after reading assembly language code, I think both of them are able to support this feature?
thanks in advance,
George

I dont think so. Only cdecl will be able to support variable number of arguments. Because in stdcall, the stack is cleaned by the called function. That means that function should know how much variables it accepts at the compile time it self.
But in the case of cdecl, the caller should clean the stack. Since the caller is pushing the variables to stack, it correctly know how much size to should pop from stack

Thanks nave,
What is the root cause why stdcall does not support variable number of input parameter? Maybe from generated assembly, we could find out?
(I think both caller and callee could get # of input parameters from stack in theory?)

George

how could callee found out the number of paremeters from the stack in the case of variable arguments? Also the size of each argument also need to be known isn't it?

Thanks nave,
I think the reason why stdcall can not have variable number of input parameter is, we can not have a common code which is capable to pop variable number of input parameters (a specific function is common code base, and needs common code to pop a specific number (not variable) of elements from stack, but if input parameter number is variable, it is impossible to have such a common code base), correct?
regards,
George

You can see the detailed explanation in the article. Basically, stdcall functions have to clean up stack themselves (as opposed to the caller function) and at compile time they have no knowledge how many parameters are there going to be passed.

Doubtful. There was some speculation a while back that he is not even human, that he is a bot.
