Hi!

I want to open dwg from template:

   DocumentCollection acDocMgr = Application.DocumentManager;

   Document acDoc;

   try

       {

              acDoc = acDocMgr.Add(FileNameTemplate);

      acDocMgr.MdiActiveDocument = acDoc

        }

   catch

       {

       }

But on the line "acDocMgr.MdiActiveDocument = acDoc" AutoCAD is hanging and in around 10 sec AutoCAD closes.

How does the new document from template set active (do current)?

You have to use CommandFlags.Seesion and also

use LockDocument

Here is a quick sample:

       [CommandMethod("opdwt", CommandFlags.Session)]
        public void testOpenFromTemplate()
        {
            DocumentCollection dm = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager;

            Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

            Database db = doc.Database;

            Editor ed = doc.Editor;

            try
            {
                using (DocumentLock doclock = doc.LockDocument())
                {

                    string tmpPath = "acad.dwt";
                    //change file name to save:
                    string fn = @"C:\Test\FromTemplate.dwg";

                    Document newdoc = dm.Add(tmpPath);

                    Database newdb = newdoc.Database;

                    using (DocumentLock newdoclock = newdoc.LockDocument())
                    {
                        using (Transaction newtr = newdoc.TransactionManager.StartTransaction())
                        {
                            dm.MdiActiveDocument = newdoc;

                            Editor newed = newdoc.Editor;

                            Point3d pt = newed.GetPoint("\nPick point: ").Value;

                            Line ln = new Line(pt, db.Extmax);

                            ln.ColorIndex = 1;

                            BlockTableRecord newbtr = (BlockTableRecord)newtr.GetObject(newdb.CurrentSpaceId, OpenMode.ForWrite);

                            newbtr.AppendEntity(ln);

                            newtr.AddNewlyCreatedDBObject(ln, true);

                            newtr.Commit();

                            MessageBox.Show("Saved as: " + fn);
                        }
                    }
                    newdoc.CloseAndSave(fn);

                    // just to work further if you wanted be:
                    dm.Open(fn, false);

                    MessageBox.Show("You can try to do your rest job here");
                }
                doc.CloseAndDiscard();
            }
            catch (System.Exception ex)
            {
                MessageBox.Show(ex.Message + "\n" + ex.StackTrace);
            }
            finally
            {
                // do nothing
            }
        }

Yeah, it works good. Thanks. It is done this way:

        [CommandMethod("calc", CommandFlags.Session)]
        public void doIt()
        {

           openFromTemplate();

            Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

            // my calculation

        }

        [CommandMethod("opdwt", CommandFlags.Session)]
        public void openFromTemplate()
        {
            DocumentCollection dm = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager;
            Document doc = Autodesk.AutoCAD.ApplicationServices.Application.DocumentManager.MdiActiveDocument;

            try
            {
                using (DocumentLock doclock = doc.LockDocument())
                {

                    string tmpPath = "my template file dwt";
                    Document newdoc = dm.Add(tmpPath);

                    Database newdb = newdoc.Database;

                    using (DocumentLock newdoclock = newdoc.LockDocument())
                    {
                        using (Transaction newtr = newdoc.TransactionManager.StartTransaction())
                        {
                            dm.MdiActiveDocument = newdoc;
                        }                 

                    }

                }

            }

            catch {}

        }

Glad you get it worked, just one note though:

Don't use empty code block for CATCH statement,

better yet to display an error message in case you

have got it,

Cheers

But it's not work for one situation.

In main function i call two methods - 1. load dwg through method readdwgfile 2. create drawing from template

In order to the second func works i add this expression above the main func

[CommandMethod("testSituation", CommandFlags.Session)]

But now the first method (readDwgFile) give me error - eNotOpenForWrite. If i remove this expression, the first method can work and the second won't work.

Test code:

[CommandMethod("testSituation", CommandFlags.Session)]
        public void testSit()
        {
            Database database = loadDWG(@"C:\...\myfile.dwg");

            openDrawingFromTemplate(@"\\tn...\A2_P.dwt");
        }

public Database loadDWG(string PathDWG)
        {
            Database newDWG = new Database(false, true);

            if (System.IO.File.Exists(PathDWG))
            {
                try
                {
                    newDWG.ReadDwgFile(PathDWG, FileOpenMode.OpenTryForReadShare, true, "");
                }
                catch (Autodesk.AutoCAD.Runtime.Exception ex)
                {
                    System.Windows.Forms.MessageBox.Show(ex.Message, "Error");
                }
                return newDWG;
            }
            else
            {                
                System.Windows.Forms.MessageBox.Show(String.Format("File {0} is not exist", PathDWG), "Error");
                return null;
            }

        }

Is such way exist which can help to solve this situation? 

[#6]

May be there are such flags which can help to work both methods?
