Re: how to wait for socket communications

I am trying to do socket communications between my C++ and my Java program.

I created a Java program for drawing curves and I connected it to Adobe's
C++ program for making a Photoshop plugin.

I am calling ShellExecuteEx for calling my Java program from C++, and it
brings up a separate window.

First I would like to communicate the Photoshop picture information into my
Java window. Originally I tried to to that with the lpParameters string in
ShellExecuteInfo, but it is too slow to build this string.

So now I am trying to communicate this with socket communication. I first
create a server in C++ before calling ShellExecuteEx, then I create a client
in Java in the main method, but how can I wait in C++ for this Java client to
be created before calling accept and sending the Photoshop picture
information?

I know I could just wait for a few seconds to make sure that my Java program
came up by calling:
if ( ei.hProcess != NULL )
{
WaitForSingleObject(ei.hProcess, 10*1000 );}

But I would rather not lose any time and just wait exactly until the Java
client is created.

And how can I wait in Java before receiving the picture information?

Finally, how can I wait in C++ for the Java program to close, at which point
the information of curves that were drawn in Java is sent to C++ (to be
received for the workpath in Photoshop)?

Thanks for your time looking at this.

Hmm, i though someone else will jump in to make this point clear. As
pointed by Alexander that using socket is not a good design approach.
His suggestion for mapped file is indeed flexible and commercial grade
solution BUT you can do that with simple file operation as i told in
previous thread. Why simple file I/O cant be your solution? and what
makes you think that sockets are good to use?
