Hi all,
I have little question that may get any programmer while using progressbar,
Lets consider following scenerio,

int j;
for(float i=0;i<1526974569745878;i++)
{
   SUM=SUM+i+j;
   j++;  
}

This loop may get 6 minute to execute.
so i want do same execution With progress bar increament.
that after some looping a progress bar increase like wise.

NOTE:<br />
1)"1526974569745878" not constant may change time to time.<br />
2)I implemented this by using OnTimer() message handler but not working.<br />
Once execution enter in loop OnTimer() function is not called.<br />

Solution 1

m_progressInit.SetRange32( 0, PROGRESS_BAR_RANGE );
// PROGRESS_BAR_RANGE (Any Integer value)
if(i%1000 == 0)
{
   if(m_progressInit.GetPos() < PROGRESS_BAR_RANGE)
    {
        m_progressInit.StepIt( );
    }
    else
        m_progressInit.SetPos(0);
}

Solution 2

You have to use separate thread for this,
Just check this Multithread article which exactly simulates your problem.

Solution 3

If this is done in the same thread as any other code, it'll block out anything else from occurring. You should reconsider doing this or figure out a better way of accomplishing what you need (threading is definitely one way).
