Macro Automatic Start when a Drawing is Opened

This got it working for me. I don't know how to run the macro when SW is open so you'll have to run the macro manually. Once it's running though, you can open and close several files and it will give you a message each time telling you what you opened.

You were on the right track for sure. You were just missing the code in your main() function to create an instance of the event listener class module you made.

Module 1:

Option Explicit


Dim eventListener As Class1


Sub main()


    Set eventListener = New Class1


End Sub

Class Module (Class1):

Option Explicit


Private WithEvents swApp As SldWorks.SldWorks


Private Sub Class_Initialize()
    Set swApp = Application.SldWorks
End Sub

Private Function swApp_FileOpenNotify(ByVal FileName As String) As Long
    Dim msgString As String
    Dim msgStatus As Integer
    msgString = "File " & FileName & "was opened."
    'swApp.SendMsgToUser msgString
    msgStatus = swApp.SendMsgToUser2(msgString, swMbInformation, swMbOk)
End Function

would you please tell us what you want to do after firing the event, open the dwg?

I had the same question awhile back and found this post with a solution from Keith Rice.  It may help you.  Been awhile but if I remember correctly it adds a macro feature to the drawing tree which you can then map to some macro.  So when you open/rebuild the drawing it runs the macro feature.  I did not 100% verify it but I did run it and it did insert the macro feature to my recollection.

John,

Are you saying that you want a macro embedded in a specific drawing document that runs any time that document is opened on any computer? Or are you saying that on a given computer, any time a drawing document is opened, you want a certain macro to run?

Eqn Triggered Macros were intended for the first case but, as you noticed, they no longer work. If you're looking for the latter, then you can set a macro to run when SolidWorks opens (and then have that macro listen for a document opening), but that's a rather frail solution as its dependent on SolidWorks being run from a shortcut you created.

What I would strongly recommend is that you write an addin, which can be set to always load with SolidWorks, regardless of how SolidWorks was opened. Addins are, in general, more robust than macros, anyway, but they are more complicated to write. If you're new to addins and/or .NET but agree that this is the best way to go for the long term, email me and I'll give you some low cost options on how we can get you started down that path.
