Control management
hi,
i have a problem to be solved.
i am using a progress bar control which runs from 1 to 100. it is initiated by a start button control. now during the process of progress bar movement i want to control it by stoping the progress bar and also stopping the start button event at that moment. this should be done by another button stop.
i tried doing it but i couldn't. i tried using timer event also, but the timer event is taken up only after finishing the start button event. is there any help?

Use two buttons Stop and Start. You can use a timer that you start and stop and in the handler increment the progress. Something like this
OnInitDialog
GetDlgItem(IDC_BUTTON_START)->EnableWindow(TRUE);
GetDlgItem(IDC_BUTTON_STOP)->EnableWindow(FALSE);
Handler for Start
GetDlgItem(IDC_BUTTON_START)->EnableWindow(FALSE);
GetDlgItem(IDC_BUTTON_STOP)->EnableWindow(TRUE);
SetTimer();
Handler for Stop
GetDlgItem(IDC_BUTTON_START)->EnableWindow(TRUE);
GetDlgItem(IDC_BUTTON_STOP)->EnableWindow(FALSE);
KillTimer();
Timer procedure
if(not-at-the-end)
StepIt();
else
{
KillTimer();
GetDlgItem(IDC_BUTTON_START)->EnableWindow(TRUE);
GetDlgItem(IDC_BUTTON_STOP)->EnableWindow(FALSE);
}

i had already implemented the way u described. And i am satisfied with that implementation. But u know one thing i found that we are not able to control or intervene inbetween a button's event and stop that event from some other button's event. Can we do it!.
thnx for ur reply,
with regards

You could use multi-threading. When you click your first button, launch a thread that will do something. You can then let the other button signal the thread to stop working.
