Hai all,
I create a windows application program, it have some crystal reports. crystal reports take 2 to 10 seconds to display because a 'loop program' work to take data from the database. I want to place a progress bar in this time. How to calculate the time taken by the 'loop program' and set 'the progress bar values'. I am the new one in this.
Thanks in advance

It's quite impossible to calculate the time the report is going to take. For this reason I'd suggest using a Marquee style progress bar to indicate that the operation is going on but the length is indeterminate.

Marquee style progress bar is like the progress bar when you open your solution in visual studio.A green light travel through the bar but no figure is shown.

C#

for(int i = 0;i < 234;i++)
{
float Percent = (float)i / 234.0f;
}

I don't understand what is so bad about it.

Sergey Alexandrovich Kryukov 28-May-12 19:55pm

Well, '234' is repeated. Do I have to explain why it's bad?

Yes you do, I was just showing the OP how to get the percentage of a loop.
It's supposed to be simple.

C#

private void button1_Click(object sender, EventArgs e)
       {
           int Maxitem = 0;
           Maxitem = 50000;
           progressBar1.Maximum = 50000; // your loop max no. 
           progressBar1.Value = 0;

           for (int i = 0; i < Maxitem; i++)
               progressBar1.Value += 1;


           MessageBox.Show("completed");
           progressBar1.Value = 0;
       }

if you know maximum number of your loop program than in this loop you will place your progess bar.
