I have a winform application that can get pretty unresponsive during heavy calculations. For example, when user presses F10 key, the program will starts some heavy stuff and remains unrsponsive for a while (I know this is not a desired way of program flow but I don’t want to alter the way program works at the moment).
Now the problem is, during this time if user presses F10 again, the program will start doing the same thing as soon as it has done the first process.
How to disable capturing keys at a certain point and enable it again?
The program is not “capturing the key”, it is queued by the operating system because your main UI-Thread is busy with your calculations and doesn’t handle anything at that time. The only thing i could think of what you could do is to check that a certain time has elapsed after the last run has finished before you allow another run. An ugly hack in my humble opinion.
But, yeah, thats why you should use backgroundworkers or threading. Using a BackgroundWorker is a lot easier than it may seem at the beginning.
