C# close/shutdown Photoshop programmaticaly

[marcinz51839902]

Hello!

I open Photoshop in my C# coded software as:

dynamic app = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.Application"));

app.open(file);

.

...

app.ActiveDocument.Close(2);

As you can see I am able to close active documents/images in C#

But...

How to close/shutdown Photoshop application instance (I mean from C# code)?

Regards

Marcin

app.quit();

Yes, it has worked but after quiting Photoshop I got error message:

System.Runtime.InteropServices.COMException (0x800706BE): Utworzenie wystąpienia składnika modelu COM o identyfikatorze CLSID {...........................................} z elementu IClassFactory nie powiodło się z powodu następującego błędu: 800706be Zdalne wywołanie procedury nie powiodło się. (Wyjątek od HRESULT: 0x800706BE).

so it means (I translated it by myself):

.....(0x800706BE). Creating element of COM model with ID CLSID {.....} with IClassFactory failed because of the error: 800706be. Remote procedure call failed (Exception HRESULT 0x800706BE)

Can you advice something how to avoid error on quitting Photoshop?

I know what happened.

I tried to open Photoshop after just closed Photoshop.

I added only one closing/quit of Photoshop in my code and the error didn`t occur anymore while app.quit().

So it works.

What is "Activator"? 🙂

[SuperMerlin]

It's the method used to get information about Photoshop in "Late Binding" (Uses the newest version of Photoshop installed)

I.E.

dynamic app = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.Application"));

dynamic ad = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.ActionDescriptor"));

dynamic ar = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.ActionReference"));

dynamic list9 = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.ActionList"));

dynamic black = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.SolidColor"));

dynamic jpgOpts = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.JPEGSaveOptions"));

etc.

Does this have some documentation? (from Adobe not Microsoft)

Does this work on MacOS?

[SuperMerlin]

I haven't found any documentation at all. The only info I found was via Google for "Late Binding". That and just experimenting.

I am Windows only here so not sure if there is the same methods for a Mac using C#

Can you call things not available in ExtendScript with this?

[SuperMerlin]

Yes you can use action manager, here is one example.

var layerInfo = getNamesPlusIDs(app);
            for (int x = 0; x < layerInfo.Count; x++)
            {
                Console.WriteLine(
                   "Layer name = " + layerInfo.Item1 +
                   " Index = " + layerInfo.Item2 +
                   " Layer ID = " + layerInfo.Item3 +
                   " Is Layerset = " + layerInfo.Item4
                   );
              }
                   Console.ReadLine();
/////////////////////////////////////////////////////
        /// <summary>
        /// Returns a Tuple:- LayerName,Index,Layer ID,is LayerSet
        /// </summary>
        /// <param name="app"></param>
        /// <returns></returns>
        static List<Tuple<string, int, int, bool>> getNamesPlusIDs(dynamic app)
        {
            int z = 0;
            List<Tuple<string, int, int, bool>> Dat = new List<Tuple<string, int, int, bool>>();
            dynamic ref1 = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.ActionReference"));
            ref1.PutProperty(app.CharIDToTypeID("Prpr"), app.CharIDToTypeID("NmbL"));
            ref1.PutEnumerated(app.CharIDToTypeID("Dcmn"), app.CharIDToTypeID("Ordn"), app.CharIDToTypeID("Trgt"));
            int count = app.ExecuteActionGet(ref1).getInteger(app.CharIDToTypeID("NmbL")) + 1;
            if (app.ActiveDocument.Layers[app.ActiveDocument.Layers.Count].isBackgroundLayer)
            {
                z = 0;
            }
            else {
                z = 1;
            }
            for (int i = z; i < count; i++)
            {
                if (i == 0) continue;
                dynamic ref2 = Activator.CreateInstance(Type.GetTypeFromProgID("Photoshop.ActionReference"));
                ref2.PutIndex(app.CharIDToTypeID("Lyr "), i);
                var desc = app.ExecuteActionGet(ref2);
                string layerName = desc.getString(app.CharIDToTypeID("Nm  "));
                int ID = desc.getInteger(app.StringIDToTypeID("layerID"));
                Match m = Regex.Match(layerName, "Layer group");
                if (m.Success) continue;
                string layerType = app.TypeIDToStringID(desc.GetEnumerationValue(app.StringIDToTypeID("layerSection")));
                bool isLayerSet = (layerType == "layerSectionContent") ? false : true;
                Dat.Add(new Tuple<string, int, int, bool>(layerName, i, ID, isLayerSet));
            }
            return Dat;
        }

I know, but I am interested in things which you can't do with action manager, DOM or scripting.

[SuperMerlin]

Not with Photoshop, but you can comunicate with other applications within the same program.
