I have a question. Is it possible, that when my program is started, it will fail to create window because the desktop doesnt have access right?

I would like to create message only window to use FD_XX socket events, and im wondering, should i care abut a specific situation when my app fail because desktop has insufficient rights. Its basically a choice between select and WSAAsyncSelect, select will work in 100% cases, while async might not if im unable to create a window.

Is i possible, that window creation will fail for some reason, other than a bug in my app or os itself?

thanks.

I don't think Window creation relates to that. Or I don't think you need rights to create a window, do you perhaps ?

If it's creating a process then Yes, but no window, I doubt it

I am not aware of any security attributes for window creation. I doubt there is such a thing.

But related is a different reason that your app may fail to create a window is lack of enough memory. Always check for success, you never know what might have happened.

tell me, is it worth using WSAAsyncSelect? Or should i stick with normal select.
Program must run on windows NT 3.1
