AcadApplication - InvokeMember

[Ertqwa]

Hello Forum,

I want to find out which members I can invoke on the class Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication, like this:

[CommandMethod("zoomExtentTest")]
public static void zoomExtentTest()
{
   Object acadObject = Application.AcadApplication;
acadObject.GetType().InvokeMember("ZoomExtents",
   BindingFlags.InvokeMethod, null, acadObject, null);
}

 However, AcadApplication returns type Object so I'm getting nowhere with "System.Reflection".

Any one knows how to list all members that I can invoke, or if there is an overview somewhere?

Thank you.

Hi,

Using Reflection of AutoCAD COM Interop, we will get all methods to invoke. The following code will get all methods of a loaded AutoCAD application:

public static Dictionary<string, string> GetAcadInteropMethods(object acadApp)
{
    if (acadApp == null)
        return null;
    var methodDict = new Dictionary<string, string>();
    MethodInfo[] methods = acadApp.GetType().GetMethods();
    foreach (MethodInfo methodInfo in methods)
    {
        string methodName = methodInfo.Name;
        string methodReturnType = methodInfo.ReturnType.Name;
        methodDict.Add(methodName, methodReturnType);
    }
    return methodDict;
}

Hi, ty for your response.

Your code returns the following:

GetLifetimeService, Object
InitializeLifetimeService, Object
CreateObjRef, ObjRef
ToString, String
Equals, Boolean
GetHashCode, Int32
GetType, Type

It does not, for example, returns "ZoomExtents", but I can invoke it. I want to find all membersI can invoke.

Sorry you could try it on existing instance of application,

then it will work like a sharm 

Something like this:

   public static class AcadInteropApp
    {
       public  static Autodesk.AutoCAD.Interop.AcadApplication AcadApp =
            (Autodesk.AutoCAD.Interop.AcadApplication)Autodesk.AutoCAD.ApplicationServices.Application.AcadApplication;

        private static AcadDocument acdoc()
        {
            if (AcadApp != null)
            {
                return AcadApp.ActiveDocument;
            }
            else
            {
                return null;
            }
        }
    }


  

        [CommandMethod("mets")]
        public static void doit()
        {
            Autodesk.AutoCAD.Interop.AcadDocument doc = AcadInteropApp.AcadApp.ActiveDocument;
            Dictionary<string, string> dict = GetAcadInteropMethods(doc);
            AcadUtility acutil=doc.Utility;
            foreach (KeyValuePair<string,string> kvp in dict)
            {
                acutil.Prompt("\nMethod name=" + kvp.Value.ToString());
            }

           // AcadInteropApp.AcadApp.Quit();

        }

        public static Dictionary<string, string> GetAcadInteropMethods(object acadApp)
        {
            if (acadApp == null)
                return null;
            var methodDict = new Dictionary<string, string>();
            MethodInfo[] methods = acadApp.GetType().GetMethods();
            foreach (MethodInfo methodInfo in methods)
            {
                string methodName = methodInfo.Name;
                string methodReturnType = methodInfo.ReturnType.Name;
                methodDict.Add(methodName, methodReturnType);
            }
            return methodDict;
        } //   Khoa     //

Hallex is right to give the full code to run the given method. Thank you.

The other replies you received all assume that you are using the COM interop assemblies, which is probably not the case, or you wouldn't need to invoke members via reflection.

If you are using late binding (e.g., not importing the COM interop assemblies) the only way to reflect on a COM object is to access its type library using ITypeInfo or ITypeInfo2 COM interfaces, which is fairly complicated.

A workaround would be to load the AutoCAD COM interop assemblies  into the reflection-only context (see  Assembly.ReflectionOnlyLoadFrom() in the docs), and then you can reflect on the the runtime-callable wrappers (e.g., AcadApplication, AcadDocument, etc.).

Hi ty for your response.

Yes you are right, all of this is to avoid using the COM interop assemblies. However, as you state yourself, I do not mind using the COM interop assemblies to get the information I need, as long as it wont end up in the final application.

Using COM interop assemblies was working fine until the application had to run on both CAD2009 (32bit) and CAD2012 (64bit).

Hi,

What about using the COM/ActiveX documentation available here:

http://usa.autodesk.com/adsk/servlet/index?id=1911627&siteID=123112

[Ertqwa]

Great thanks, found a list in acadauto.chm.
