Question

In the application i am working on, there are several forms; one used for the purposes of displaying 3d images, and other for governing that. Some changes in the images are time-consuming, and while they are going through, both of forms are not being redrawn.

What i would like to achieve is for at least controlling form (that is composed from fairly standard components only) to continue interaction with user and continue being redrawed. The way i see it, it should be moved into different thread, as the thread it is using now is too busy.

How should i do that? Wil Application.Run(secondForm) be sufficient?

You should do the heavy lifting in another thread. You can use a background worker to keep things easy or manage your own threads.

Something like this:

• Controller form presses start => Start a thread/backgroundworker and do your calculations in it
• When the calculations are done, update your image form. You could call an event when its done and let your image/controller form subscribe to it.
• Or when the controller form changes something before the calculations are done, you can cancel the backgroundworker and start again.
