How to show wait cursor with message in windows application using c#

Hi,
before calling the expensive operation you can set up the cursor via this code:

this.Cursor = Cursors.WaitCursor;

after the operation ends, set it back:

this.Cursor = Cursors.Default;

Regards

private void button1_Click(object sender, EventArgs e)
{
DialogResult dr = MessageBox.Show("Use of wait cursor", "Top", MessageBoxButtons.OKCancel);


if (dr==DialogResult.OK)
{
Cursor = Cursors.WaitCursor;

for (int i = 0; i < 1000000000; i++)
{


}

Cursor = Cursors.Default;
}




}

Do like that

private void mnuPreview_Click(...)
{
Cursor = Cursors.WaitCursor;
.
.
.//your logic
.
.
Cursor = Cursors.Default;
}
