Hi Guys,

I have a DLL loaded into a 3rd Party application (AutoCAD). Once loaded i can trigger commands to load winforms to do things with in AutoCAD.

One of my commands loads a dialog.

How I Test if that Dialog is already running and not load the Winform again and just make it active / on top of all other applications?

Thanks in advance.

Hi Stephan,


if you want to find particular form is already opened or active. i thing the following may help you.

List<MyForm> CurrentActiveForms = System.Windows.Forms.Application.OpenForms.OfType<MyForm>().ToList();
if(CurrentActiveForms.Count == 0)
{
	// No match form found !!!!
	// request a new form to open
	return;
}
 
// do your stuff here........
MyForm DesireForm = CurrentActiveForms.FirstOrDefault(I => I.MyCondition == myCondition);
 
Or
 
MyForm DesireForm = CurrentActiveForms[0];
 
if (DesireForm != null || DesireForm.IsDisposed == false)
{
    DesireForm.focus();
}
