[DUG] Sending data between process on same computer on windows

[Ross Levis]

I should add that I use a timeout counter in the while loop in case the
service app is not operating or functioning.

In my case it's in a normal gui application at one end and a service type
application in the other which uses a timer to check for incoming commands.

 

I normally do something like this.

 

ShareRec.Filename := 'Whatever';

ShareRec.Command := 2;

While ShareRec.Command <> 0 do Sleep(10);

 

The service application detects the command = 2, does something with the
filename, and sets command to 0 when finished.  The While loop usually only
executes once so there is no delay for the user.. 

 

You could run this in a thread if it was going to take a while.

 

I didn't know about NewInstance to allocate the object where you need it.
There is still an issue with strings and pointers inside the object.  Simple
records work well enough for me.

 

Ross.
