window blocked when the application is running c#

Question

I have a small application coded on c# (Windows Form)(visual stud 2012) when I run the application it work properly except that when the application is running i can't no more click on the window or even move it, until it finish the process how can I solve this problem ?

Move the work to a separate thread. Search here for `[c#] Background worker`. — Ken White, Jun 20 '13 at 15:57
So the thread is busy. Hmm. Could you share the code you are using that is taking up the thread? Maybe we can give some pointers. — SchautDollar, Jun 20 '13 at 15:58

You could implement the BackgroundWorker Control/Class.

To do this, just drag the control BackgroundWorker from the toolbox on to the form. Select the background worker you just created and double-click on it. Now put all the code you need to do separately from the UI into this event.

Example:

//Assuming we have a background worker called backgroundWorker
private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e) {

     //put code here

}

Now in the triggering block of code, call backgroundWorker.RunWorkerAsync().

Example:

private buttonDoWork_Click(object sender, EventArgs e) { 
    backgroundWorker.RunWorkerAsync(); 
}

Just be careful and be threadsafe.

woooow !!! it's fixed now :D Thank you i will try to make the same thing to fix the progress bar update — user1863359, Jun 20 '13 at 16:45

Have a look at using BackgroundWorker Class

Executes an operation on a separate thread.

The BackgroundWorker class allows you to run an operation on a separate, dedicated thread. Time-consuming operations like downloads and database transactions can cause your user interface (UI) to seem as though it has stopped responding while they are running. When you want a responsive UI and you are faced with long delays associated with such operations, the BackgroundWorker class provides a convenient solution.

Threads again :( i'm not so good on the thread things, but i will try to have an idea about it (i was trying to make a progress bar with a thread but finally i let it down) – user1863359 Jun 20 '13 at 16:00
I don't know how to put my code on the : private void backgroundWorker_DoWork(object sender, DoWorkEventArgs e) {} because the method that take a lot of time is called when the user click on a button public partial class Welcome : Form { private BackgroundWorker backgroundWorker1; public Welcome() { } private void Button3Click(object sender, EventArgs e) { //call a method that take a lot of time } } – user1863359 Jun 20 '13 at 16:32

Sounds like you are doing your processing on the UI Thread. Any processing you do on the UI thread takes away cycles that User Interface events can be serviced.
