From the SWAddin Template...

SW2007 x64...

I am trying to figure out the toolbar or UI functions.

In this function:

Public Sub AddCommandMgr()

Dim cmdGroup As ICommandGroup

Dim iBmp As New BitmapHandler

Dim thisAssembly As Assembly

thisAssembly = System.Reflection.Assembly.GetAssembly(

Me.GetType())

cmdGroup = iCmdMgr.CreateCommandGroup(1,

"SW Custom Tools", "Custom SolidWorks Macros", "", -1)

cmdGroup.LargeIconList = iBmp.CreateFileFromResourceBitmap(

"SWCustomTools2007.ToolbarLarge.bmp")

cmdGroup.SmallIconList = iBmp.CreateFileFromResourceBitmap(

"SWCustomTools2007.ToolbarSmall.bmp")

cmdGroup.LargeMainIcon = iBmp.CreateFileFromResourceBitmap(

"SWCustomTools2007.MainIconLarge.bmp")

cmdGroup.SmallMainIcon = iBmp.CreateFileFromResourceBitmap(

"SWCustomTools2007.MainIconSmall.bmp")

'cmdGroup.AddCommandItem("Link2BOM", -1, "Link all relevant views to BOM", "Link all relevant views to BOM", 0, "Link2BOM", "EnableLink2BOM", 0)

"CreateCube", -1, "Create a cube", "Create cube", 0, "CreateCube", "", 0)

cmdGroup.AddCommandItem(

"Show PMP", -1, "Display sample property manager", "Show PMP", 2, "ShowPMP", "EnablePMP", 2)

cmdGroup.HasToolbar =

True

True

Nothing

End Sub

EnablePMP is the call to enable or diasable this button, this function was named PMPEnable in the template which I am assuming was wrong.

Function EnablePMP() As Integer

If iSwApp.ActiveDoc = Nothing Then

Else

End If

End Function

so if there is no doc open then the button is disabled.

running this in debug mode the following appears in the Immediate Window:

A first chance exception of type 'System.InvalidCastException' occurred in Microsoft.VisualBasic.dll

If I comment out everything in the EnablePMP() function then the msg in the immediate window does not appear but then the button does not get enabled or disabled. I am trying to get a button the I am adding to only be anabled when a drawingdoc is active but I came across this message. How do I fix it?

thanks in advance...
