control z-level of forms

wbdehaan — Thu, 03 Mar 2016 13:02:58 GMT

Hi,

When I:

1. start a windows form in AutoCad with .show (modeless form) or .showdialog (modal form),

2. start another form inside this form,

3. close this second form with .hide

..most of the time other open applications like Outlook, or notepad appear in between AutoCad and the first opened form. How can I keep the forms always on top of AutoCad and prevent other applications from appearing? Only when AutoCad is active

I think Gui.topmost is not an option, because when I need to switch to another application, this form remains on top.

kind regards

I have seen this behaviour before. I believe the answer is don't use hide in the 2nd form. Hide or dispose the 2nd form from the 1st.

I have also used dialog result if necessary. If the 1st form needs a response from the 2nd, you can use dialog result.

Form1 myform = new Form1();
acapp.Application.ShowModalDialog(null, myform, false);
if (myform.DialogResult == DialogResult.OK)
{ }

myform.dispose();

Form1 could contain something like this:

private void cmbOK_Click(object sender, EventArgs e)
{
DialogResult = DialogResult.OK;
// don't use hide - there is a screen flash of other open windows (like explorer)
// Hide();
}

Hi Thanks,

I started the interfaces with .show and .showdialog instead of acapp.Application.ShowModalDialog(Gui)

kind regards
