Topic: how to use acedInvoke in AutoCAD 2007,2008 and 2009

[guohq]

Since AutoCAD 2011, the Application.Invoke method is provided. I want to implement this function in Autocad 2007,2008 and 2009, but acedInvoke does not seem to work.

       <DllImport("acad.exe", EntryPoint:="acedInvoke", CallingConvention:=CallingConvention.Cdecl, CharSet:=CharSet.Auto), System.Security.SuppressUnmanagedCodeSecurity()> _
        Private Shared Function acedInvoke(ByVal args As IntPtr, ByRef result As IntPtr) As Integer

        End Function

here is the test code

(defun c:GetVariableValue(VarName)
   (eval (read VarName))
)
(Setq aa 1234321)


acedInvoke(New ResultBuffer(New TypedValue(LispDataType.Text, "GetVariableValue"), New TypedValue(LispDataType.Text, "aa"))



The above code runs fine in AutoCAD2010.

sorry ,I use the wrong code. the right code is

acedInvoke(New ResultBuffer(New TypedValue(LispDataType.Text, "c:GetVariableValue"), New TypedValue(LispDataType.Text, "aa"))
