Auto-Run Macro leading to system being in unstable state message

Question asked by Rick Hombsch on Jan 25, 2016

I am trying to auto-run an embedded macro as shown here:

The macro is used to modify design table values based on custom property inputs. The macro runs and updates the design table as needed however I get the following error (see below). Also sometimes I may get a corrupted design table. The macro I am running is shown below and only runs when the RunMacro custom property is 0. Attached is a simplied version of what I am trying to do however the premise is the same.


Sub main()



Dim valOut   As String

Dim resolvedValOut      As String

Dim swApp As SldWorks.SldWorks

Dim swModel As SldWorks.ModelDoc2

Dim swDesignTable As SldWorks.DesignTable

Dim CellValue As String

Dim boolstatus As Boolean


Set swApp = Application.SldWorks


Set swModel = swApp.ActiveDoc

Set swCustPropMgr = swModel.Extension.CustomPropertyManager("")


'RebuildMacro Variable Used to Only run code on first rebuild

swCustPropMgr.Get2 "RebuildMacro", valOut, resolvedValOut

MacroRunValue = valOut


'Get Length Width Height

swCustPropMgr.Get2 "LENGTH", valOut, resolvedValOut

Length = valOut

swCustPropMgr.Get2 "WIDTH", valOut, resolvedValOut

Width1 = valOut

swCustPropMgr.Get2 "HEIGHT", valOut, resolvedValOut

Height = valOut


'If the model is rebuilt for the first time (MacroRunValue = 0)

If MacroRunValue = 0 Then


'Get Design Table

Set swDesignTable = swModel.GetDesignTable

'Edit Design Table


'Changes the first data row second colum to the cell value

swDesignTable.SetEntryValue 1, 0, False, Length

swDesignTable.SetEntryValue 1, 1, False, Width1

swDesignTable.SetEntryValue 1, 2, False, Height


'Update Design Table

boolstatus = swDesignTable.UpdateTable(SwConst.swDesignTableUpdateOptions_e.swUpdateDesignTableAll, True)

'Set RebuildMacro Custom Property to 1 so macro does not run again

swCustPropMgr.Set "RebuildMacro", 1

End If


End Sub
