Topic: Layouts

[Kerry]

I've started to play with Layouts .. heading towards Plotting [expect this to be a long path ]


Anyone want to give this a run .. ?
The routine is designed to display the Names of All Layouts defined in the Document.

The initialiser may be of interest too.

... and the obligatory piccy ..

.. and these are the Locals after the first run through the foreach loop.

I'm finding that the Locals, the Browser/Reflection is helping me make a pretty good guess regarding whats going on.

[Mr. Bean]

Nice! works great here

I like this ...

Code: [Select]

using AcDb = Autodesk.AutoCAD.DatabaseServices;
using AcEd = Autodesk.AutoCAD.EditorInput;
using AcRx = Autodesk.AutoCAD.Runtime;

Hope you don’t mind me borrowing stuff 

edit

And I do like the initialiser I’ve never seen this

[Mr. Bean]

layoutMgr does not need to be disposed because it’s not a "new" LayoutManager right?

[Kerry]

It's a good learner Dan.

Re the 'borrowing'  ... whats round comes around .. I notices the concept on one of the chinese sites ages ago .. just starting to make use of it sometimes. I thought it may help me learn where everything comes from without increasing the keystroke count too much.

[Kerry]

layoutMgr does not need to be disposed because it’s not a "new" LayoutManager right?

Thats my understanding ... but I'd be happy to be corrected.

And I do like the initialiser I’ve never seen this

Yeah, I became tired of forgetting the command Name I need to type to get test stuff to run 

When I use more that one callable method especially .. I just add an extra line to the Initialiser for each command.

[Kerry]

Next one .. needs some refining ..

If anyone can see anything that looks questionable or could do with a rev' please yell. 

add this Method to the same class as the previous ..

Code - C#: [Select]

1.        
2.         [AcRx.CommandMethod("kbPSL")]
3.         static public void
4.             ListPlotStylesForLayouts()
5.         {
6.             AcDb.Database db = HostApplicationServices.WorkingDatabase;            
7.             AcEd.Editor ed = AcadApp.DocumentManager.MdiActiveDocument.Editor;
8.             //            
9.             try
10.             {
11.                 using (AcDb.Transaction tr = db.TransactionManager.StartTransaction())
12.                 {
13.                     using (AcDb.DBDictionary layoutDict = (AcDb.DBDictionary)tr.GetObject
14.                                              (db.LayoutDictionaryId, AcDb.OpenMode.ForRead))
15.                     {
16.                         foreach (DictionaryEntry layoutEntry in layoutDict)
17.                         {
18.                             using (AcDb.Layout  layoutObj = (AcDb.Layout)tr.GetObject
19.                                                 ((AcDb.ObjectId)(layoutEntry.Value),AcDb.OpenMode.ForRead))
20.                             {
21.                                 string strStyleSheet = layoutObj.CurrentStyleSheet.ToString();
22.                                 if (strStyleSheet.Length == 0)
23.                                 {
24.                                     ed.WriteMessage("Layout.LayoutName = " + layoutObj.LayoutName
25.                                         + ", StyleSheet = " + "nada - tough luck" + "\n");
26.                                 }
27.                                 else
28.                                 {
29.                                     ed.WriteMessage("Layout.LayoutName = " + layoutObj.LayoutName
30.                                         + ", StyleSheet = " + strStyleSheet + "\n");
31.                                 }
32.                             }
33.                         }
34.                     }
35.                 }
36.             }
37.             catch (System.Exception ex)
38.             {
39.                 MessageBox.Show(ex.ToString());
40.             }
41.         }

and replace the  Initialize() Method with this ..

Code - C#: [Select]

1.         public void
2.             Initialize()
3.         {
4.             //Let the user know what's happening while loading your stuff  
5.             AcEd.Editor ed = AcadApp.DocumentManager.MdiActiveDocument.Editor;
6.            
7.             ed.WriteMessage("\nConcept Code For AC2007, MSVS2005 :: kwb@theSwamp 20070112 ...");
8.             ed.WriteMessage("\nUse kbLAL at command line to List all Current Layout Names\n");
9.             ed.WriteMessage("\nUse kbPSL at command line to List PlotStyles For Layouts \n");
10.         }

and the piccy ...

[Kerry]

Next one :
Device Names for the Active Layout using COM ActiveX in C# [ no apologies ]

Add this to the usings and reference the COM Dll's..

Code - C#: [Select]

1. //// COM Interop References
2. //// AutoCAD 2007 Type Library
3. //// AXDBLib AutoCAD/ObjectDBX Common 17.0 Type Library
4. using AcInt = Autodesk.AutoCAD.Interop;
5. using AcIntC = Autodesk.AutoCAD.Interop.Common;
6.  

Add this to the main Class ..

Code - C#: [Select]

1.         [AcRx.CommandMethod("kbPDN")]
2.         static public void GetPlotDeviceNames()
3.         {
4.             AcEd.Editor ed = AcadApp.DocumentManager.MdiActiveDocument.Editor;
5.  
6.             // Use the COM ActiveX interface to extract the devices from the activeLayout
7.             //
8.             AcInt.AcadApplication appCOM = (AcInt.AcadApplication)AcadApp.AcadApplication;            
9.             AcIntC.AcadLayout activeLayout = appCOM.ActiveDocument.ActiveLayout;
10.            
11.             // generic System.Object
12.            Object plotDevices = activeLayout.GetPlotDeviceNames();
13.             // Array of device Names
14.            Array plotDeviceArray = (Array)plotDevices;
15.            
16.            //
17.            ed.WriteMessage("\nPlot Device List for :"  + activeLayout.Name) ;
18.            foreach (string nameStr in plotDeviceArray)  
19.            {
20.                ed.WriteMessage("\n " + nameStr);
21.            }            
22.         }
23.  

And the Piccy

[Kerry]

.. and the same from the managed API using PlottingServices ..

Add this to the usings ;

Code: [Select]

using AcPS = Autodesk.AutoCAD.PlottingServices;
Then add this to the Class

Code - C#: [Select]

1.         [AcRx.CommandMethod("kbPDNN")]
2.         static public void PlotDeviceNamesNet()
3.         {
4.             AcEd.Editor ed = AcadApp.DocumentManager.MdiActiveDocument.Editor;
5.             ed.WriteMessage("\nPlot Device List In Net :"  );
6.             foreach (AcPS.PlotConfigInfo pci in AcPS.PlotConfigManager.Devices )
7.             {
8.                 ed.WriteMessage("\n " + pci.DeviceName );
9.             }
10.         }

and the piccy .. same result !

[Kerry]

This one was fun !! .. had a play with a generics list ..
not sure if it's correct [best way etc] , but it works !!!

Code - C#: [Select]

1.         [AcRx.CommandMethod("kbPDN-1")]
2.         static public void PlotDeviceNamesNet_1()
3.         {
4.             AcEd.Editor ed = AcadApp.DocumentManager.MdiActiveDocument.Editor;
5.             ed.WriteMessage("\nPlot Device List In Net :");
6.  
7.             AcPS.PlotConfigInfoCollection plotDevices = AcPS.PlotConfigManager.Devices ;
8.  
9.             // use a bit of the NET generics
10.             //
11.             List<string>  plotDeviceList = new List<string>();
12.  
13.             //// lets build a list [collection]to use later ...
14.            
15.             foreach (AcPS.PlotConfigInfo pci in plotDevices )
16.             {
17.                 plotDeviceList.Add(pci.DeviceName);
18.             }
19.  
20.             // Print it out just to proove it ..
21.             foreach (string deviceName in plotDeviceList)
22.             {
23.                 ed.WriteMessage("\n " + deviceName);
24.             }
25.         }
26.  

The debug Locals for the built List ..
.. and the command line piccy ..

[Mr. Bean]

Oh yea managed API version is much cleaner. I almost forgot all about that ActiveX stuff  

[Mr. Bean]

.. had a play with a generics list ..

Ha! I was just doing the same thing!!! List<string>  plotDeviceList = new List<string>();
That’s funny

[Kerry]

Great minds think alike, fools never differ  .. etc ...

Today has been a good day Dan !

[Kerry]

Just a thought ..

If we can get a couple of people adding working Methods to this thread it won't take long before we start to understand the Plotting and Layouts Namespaces. 

... simple single purpose snippets will me fine, thank you ! 

[kdub]

Jeeeze , time flies !!
