Hello,
I want to open a FolderBrowserDiaog when a Batch Task is initialized. The problem, the Dialog does not appear. It appears to be invisibel.
I think I have to set the parent form. How to I get access to it? Or is there a better solution?
Thanks
Hi Andre,
I see the problem now.
Tasks are run on separate threads and the FolderBrowserDialog is special (a shell dialog), which is why you cannot see the dialog.
See 
for more details.
Try adding the following code to the OnIntializeTask method:
Translate
DialogResult r = DialogResult.No;
FolderBrowserDialog dialog = new FolderBrowserDialog();
var t = new Thread(() => r = dialog.ShowDialog());
t.IsBackground = true;
t.SetApartmentState(ApartmentState.STA);
t.Start();
t.Join();
if (r == DialogResult.OK)
{
var folder = dialog.SelectedPath;
}
