GUI unresponsive on high CPU utilization

[JeffPalmer]

I wrote a Delphi 6 app that processes a text file and then populates an Access database. The program pegs the CPU, but otherwise runs fine (even though task manager shows it not responding). It does take some time for the program to run, so I added an abort button and status gauge. The gauge updates fine. The problem is that it is so busy with the calculations, it doesn't even change focus to the abort button when pressed. I tried adding a Refresh in the looping calculation, but other than some flickering in the window, I still get no response.

How can I can get it to check if the abort button was pressed with the least impact on processing?

Hi,

put application.processmessages in cpu intensive code parts, this will improve app response. Other option is to move cpu intensive tasks to antoher thread, freeing up the main GUI thread, but this is more complicated...

That did it! Wasn't even a noticeable performance hit!

I completely forgot about that command.

Thank you so much!
