Form responding slow

Hi,

I got 2 forms. From1 has buttons and some checkboxes to start a test after a button is pressed.

If a button is pressed, it opens Form2. When i'm done with Form2 i close it.

Then i get back to Form1 and then it starts responding slow.

This only happens when i start a test that has filestreams and filereaders and some more stuff with files involved.

How can i see whats making it slow I disposed everything in Form2 when it gets closed.

Even when i close the Form1 its still running, I have to press the 'stop' button in order to continue.

Any suggestions anyone

Thanks in advance!

Time to break-out the debugger. Set a breakpoint on the DoEvents() call. From there, figure out why the loop isn't exiting...

You've still got code running, stuck in a loop. Using DoEvents

Hi nobugz,

I got it fixed. I did a "rollback" on my code and tried it again with that peace of code, and it works.

Also, i did it in the wrong while loop.

So... problem solved.

Thank you for your time and patience!

Try to comment parts of your code and run to acote the responsable code fragment.

In the task manager view large amount of cpu usage

No, your while loop keeps running, as you found out. To break out of the while loop, set a boolean form class member to true if the FormClosing event, one you test in the loop. For example:

public partial class Form1 : Form {
public Form1() {
InitializeComponent();
}
private bool mBreakLoop;
private void Form1_FormClosing(object sender, FormClosingEventArgs e) {
mBreakLoop = true;
}
private void DoWork() {
mBreakLoop = false;
while(!mBreakLoop) {
// Do the work
// ...
Application.DoEvents();
}
}
}

Hi guys,

Thank you for your reply.

I got DoEvents in a while loop which is in Form2. But if i close Form2 isn't DoEvents stopped too, or do i have to stop it with code

On Form1 i don't have anywhere 'DoEvents'.

Hi nobugz,

I did exactly what you told me to do. The problem still remains.

I have nothing on 100% cpu usage when i run my app.
