VBA for Excel question (VB6)

pedestrian

The following code is a VB6 Standard EXE. I create an Excel app using
OLE Automation. I only want One Excel app to be opened at one time.
If the Excel app is already opened, I reuse it to update the cell value.

If the user close the Excel and re-click the Command1 button in the VB app, the app should create a fresh excel app. However, the code below show runtime error. How to check whether the user have close the Excel app created by VB? Please advise... Thanks.

P/S: Message wrongly posted to Basic messagebox instead of VBA.

Private Sub Command1_Click()
If myApp Is Nothing Then
Set myApp = New Excel.Application
myApp.Workbooks.Add
myApp.Visible = True

myApp.Cells(1, 1).Value = "Hello"
End Sub
