Have a bool value and set it to true when the export object is created.

bool exportCreated = false;

private void View_Click(object sender, EventArgs e)
{
if (!(exportCreated))
{
Export export = new Export();
export.Show();
exportCreated = true;
}
}

Until you set exportCreated to false a new export object will not be able to be created. Cheers Kev

You can show your form as modal dialog private void View_Click(object sender, EventArgs e) { Export export = new Export(); export.ShowDialog(this); } DevIntelligence.com - My blog for .Net Developers

hi! :) you can also try this... :) private Export m_frmExport = null; private void View_Click(object sender, EventArgs e) { if (m_frmExport == null || m_frmExport.IsDisposed) { m_frmExport = new Export(); m_frmExport.Show(); } else { //If the m_frmExport is not yet closed/disposed, this will set the focus on this form. m_frmExport.Activate(); } } hope that helps. :)

is your export form should be modal? If not, you can make your export form as class member and construct it in your main form contstructor and at View_Click(..) you can write only exportForm.Show(); Hope this help Hesham
