Thread priority over Main program

[msteffes]

Hello All,
I am new to working with threads and need to understand better how priority settings affect other tasks.
My project barrows the example code in the help file section for < CreateSemaphore()> It is Producer/consumer code . I have attempted using this approach in an RS485 sniffer program for a proprietary messaging protocol. I have a thread created that will gather serial data and stuff it in to a shared List. The main program then processes the data in to meaningful messages, writes them to a file and strips the processed data of the top of the list. The problem I have run into is the Data processing in the main seems to go through the data faster than the serial thread can populate the List object. I found this very surprising as the data processing portion is a bit complex, at least to me. The serial data is streaming at about 100millisecond message interval. This is about half the speed I anticipate once I get beyond the simulation stage I have tried a very high ThreadPriority() to the Producer but the main still out runs the producer thread. Do I need to put the Data processing in to a separate thread as well, taking it out of the main line code?

You need to tell the main loop when threre is data to process.
Look at PostEvent() with custom events.
