    text
    copied!<p>I am extremely Sorry for this long post. I need some help on c# wpf issues. I have build a complicated UI(somehow) and there is some buttons... like start and stop and others.</p> <p>When i click the start button a execution process starts with communicating with some protocol layer and others and it is a long process .. and during this process i have to show some notification UI like "Enter a Text", "Select Something" etc... this time i have to show some wpf window object... and after some time i have to automatically destroy the window and go with processing again.</p> <p>At first i tried to run the execution in the Main window class. But it results that when the execution starts.. user can't click anything and ui doesno't respond rather just hangs. I investigate the problem... and found that UI is busy with processing in the execution on protocol layer so its not responding.</p> <p>Here is my problem... can u give me some solution that...</p> <ol> <li>i will have 2 button..start and stop</li> <li>when i click the start button... a large process will start( like nested for loop with a large int which will continue for 50 seconds) in function named Processor.</li> <li>at time of processing the function Processor will create several window and show them wait for 5-10 seconds and also destroy them. or user click;s on the window</li> <li>And the whole time the stop button should be clickable so that when i click the stop button .. the process should be stop.</li> </ol> <p>I tried this with backgroundworker, dispatcher... and using separate thread. but no luck. I guess i am missing something. because if i wait for some result showing a window..the window will definitely hang.. and if i separate them with different thread.. it will not communicate with each other. please give me some suggestions</p>
