Bring document foreground (activate document) using SOLIDWORKS API

This example demonstrates how to bring the document selected by path to foreground (make active) using ISldWorks::ActivateDoc3 SOLIDWORKS API.

Document can be opened in 2 states (visible or hidden). Hidden document are usually models which are loaded into the memory from the components in the assembly or drawing. In this case when ISldWorks::OpenDoc6 method is called the document will not be brought foreground automatically. Similar scenario applies to closing the document which is loaded as a component: document will be made invisible rather than closed.

Run the macro when no files are opened - file will be opened and closed
Open assembly and run the macro. In this case ISldWorks::OpenDoc6 API doesn't force the part to be brought foreground, so it is required to force activate it.

    path = swApp.GetCurrentMacroPathFolder() & "\" & FILE_NAME
    
    Set swModel = swApp.GetOpenDocumentByName(path)
    
    Dim wasVisible As Boolean
    
    If Not swModel Is Nothing Then
        wasVisible = swModel.Visible
    End If
    
    Set swModel = swApp.OpenDoc6(path, swDocumentTypes_e.swDocPART, swOpenDocOptions_e.swOpenDocOptions_Silent, "", 0, 0)
    
    If Not swModel Is Nothing Then
        swApp.ActivateDoc3 swModel.GetTitle(), False, swRebuildOnActivation_e.swDontRebuildActiveDoc, 0
    End If
    
    MsgBox "Was Visible: " & wasVisible
    
    If False = wasVisible Then
        swApp.CloseDoc swModel.GetTitle
    End If
