Questionissue with progress bar Pin
gtag2-Nov-08 23:32

There are two issues :
1. My windows application contain many number of controls like, buttons, textboxes,checkboxes etc..
Application is very slow while execution and even for any button click event application hangs for a while(atleast 8 seconds).

Used panel and group box but same status.

2.While execution i have to show one progress bar for particular button click event. And need to increment progress bar in sync or simultaneously with button click event execution.

Example: (only a part of the code i am writing here in blog):

Two forms form1 & form2:

on form1 button click event some code is executed.
say form1 code:

form2 trs = new form2();
btn_click
{
trs.Show();
trs.Owner = this;
trs.go(this);
Thread thred = new Thread(new ParameterizedThreadStart(trs.go));
string strngmain = "a";
....do something........(here actual code executes, while this executes,i want to show the status in progress bar, so while execution i am adding one char to string variable strngmain)

}

written one method in 1st form:
public void UpdateProgress(int progress)
{
if (InvokeRequired)
Invoke((MethodInvoker)delegate() { trs.progressBar1.Value = progress; });
else
trs.progressBar1.Value = progress;
}
where 'trs' is a instance of form2 declared in form1.

No. of times 'a' char is added in single button click event to a string declared called "strngmain". And depending upon each char progress bar status should get incremented in 2nd form.

Form2: It contains one progress bar which should increment depending upon the button click event execution:

Code in form2:
form2_load
{
progressbar1.show();
}
public void go(object param1)
{
MainForm form = (MainForm)param1;
string strng;
srtng = ((MainForm)this.Owner).trans_complete;
foreach(char c in strng)
{
form.UpdateProgress(10);
Thread.Sleep(10);
}
}

But the above code is not working correctly , progress bar is not incrementing in sync with mainform's button click event code execution.

Any help appreciated.

Thanks in advance.
