Topic: From a running program pass variables to another running program

Hello, I'm trying to work on a project where I have two running applications and I want both apps to be able to communicate with each other. For example Program A runs and calls Program B with some parameters. Program B processes the parameters and saves the output to text file. Program A then opens the output file and reads the data.  This process works but there is a big delay when saving and reading from the output file. I want to speed up the process, maybe using TMemoryStream  or  TStream to save a variable from one program to other or is there another way? Also I'm not using any databases for these two programs. Any help will be appreciated it. Thanks.

You can pass parameters through the system registry.
Class TRegistry.

Sorry for delay, I was on vacation.  Is your question still actual for you?

Re: From a running program pass variables to another running program

yes, I will like to have a way to pass some variables between two running programs.  Writing to the hard drive is a slow process, using memory will be a lot faster.

Unfortunately MVD can't suggest fast way to communicate between two applications, only using files.
