Calling a GUI from excel and keeping it open

Hi there, need a way to keep a GUI called from excel VBA code open, I am using matlab automation server as my code below shows:
Private Sub openmatlab()
Dim hMatlab As Object
Dim sDir As String, scdDir As String, s1 As String
Dim Result As String
Set hMatlab = CreateObject("matlab.application")
s1 = "'"
sDir = s1 & ActiveWorkbook.path & s1
scdDir = "cd(" & sDir & ")"
hMatlab.Execute (scdDir)
Result = hMatlab.Execute("starter")
MsgBox "Matlab er lukket", vbOK, "Matlab"
End Sub
As you might be able to see I am using a messagebox to stop the GUI from shutting down, but that makes excel "blink" all the time, and is annoying, any thoughts on how to do it better?

In your VBA code you could try the option
Application.ScreenUpdating = False
I have no experience of running matlab from Excel, but that used to stop the "blinking" back in the day when I ran macros.

yeah, already tried that, but it doesn't work, besides I would like a solution that doesn't involve using the msgbox, which is kinda 'cheating' in my opinion.

if you provide a bit more details?
What is your matlab function doing? Is it a GUI? and do you want to wait until the GUI closes before control returns to excel?
If so have you tried uiwait(yourGUIHandle). That should stop it.
