Bt Window Still Invisible After Setting Visiblewindows As All
The following is my system's environment:
.net 4.0
IIS7
vs 2010
win7
Bartender 10.0SR4 Automation
In task manager, there is a bartend.exe instance but there is no visble window of the BT instance.
The development server runs without a problem.
codes:
try
{
Engine btEngine = new Engine();
btEngine.Start();
// Make BarTender visible to the user.
btEngine.Window.Visible = true;
btEngine.Window.VisibleWindows = Seagull.BarTender.Print.VisibleWindows.All;
Messages message = new Messages();
LabelFormat lf = new LabelFormat(this.Server.MapPath(@"../LabelTemplates/94X158-v3.btw"));
LabelFormatDocument btFormat = btEngine.Documents.Open(lf, out message);
if (!(btFormat is LabelFormatDocument))
{
btEngine.Stop();
continue;
}
btFormat.SubStrings["PO"].Value = io.PO;
btFormat.SubStrings["POItem"].Value = hl.CustomerPoItem;
...
}
catch (Exception ex)
{
Master.ValidationErrors.Add("Error.");
Master.ValidationErrors.Add(ex.Message);
Master.ValidationErrors.Add(ex.InnerException.Message);
return;
}

What happens if immediately after making the Window visible you sleep the system for 5 seconds, will you then see the visible window?
// Wait five seconds so the user can see the window. System.Threading.Thread.Sleep(5000);Furthermore, the bartend.exe process you see in task manager, is it running under the same Windows account than you're currently logged under?

No, it is the same as before.
And the bartend.exe is running under the same Windows account.

If BarTender is being run under a service context (which seems to be the case as you're using IIS), BarTender cannot be made visible because interactive dialogs are not allowed in newer versions of Windows. This is because Windows discovered that this was a security flaw.

Is there any workaround? Does Windows XP work this way?

Services cannot directly interact with a user as of Windows Vista, so yes, on Windows XP the behaviour should be different, but please be aware that running interactive dialogs while running under a service context is a security risk and this is why Microsoft has blocked this in newer versions of Windows.
