Adding Xdata to a database that's not opened in the editor

[amasutti]

Hi, I'm Using C# to add Xdata to a block reference in a database that's opened in I guess you would call it a Side Data base (not in the drawing Editor). I'm checking for the Registered app and creating it if it doesn't exist. But when it comes to writing the Xdata I get an error EappIdNotFound. I'm Opening the Other drawing database Read-Write. Any Help Would be appreciated. Thanks in advance.

private void PutXdataDate (ObjectId objEntId, string strAppName,string Jdate)
        {
            Database objDB = objEntId.Database;
            Transaction objTrans = objDB.TransactionManager.StartTransaction();
            Entity objEnt = (Entity)objTrans.GetObject(objEntId, OpenMode.ForWrite, false);
            Database db = HostApplicationServices.WorkingDatabase;
            // RegAppTable acRegAppTbl;
            

            using (Transaction acTrans = db.TransactionManager.StartTransaction())
            {
               var acRegAppTbl = (RegAppTable) acTrans.GetObject(db.RegAppTableId, OpenMode.ForRead);
                if (acRegAppTbl.Has(strAppName) == false)
                {
                    RegAppTableRecord acRegAppTblRec = new RegAppTableRecord();
                    acRegAppTblRec.Name = strAppName;
                    acRegAppTbl.UpgradeOpen();
                    acRegAppTbl.Add(acRegAppTblRec);
                    acTrans.AddNewlyCreatedDBObject(acRegAppTblRec, true);
                    acTrans.Commit();
                 }

Nevermind I figured it out. I was creating the Registered app in the working Database not the Side Database. Instead of DN I created in in objDB. Thanks anyways.

[_gile]

You add the registered application to the the RegAppTable of the working database (HostApplicationServices.WorkingDatabase). Is it the same as the 'objDb' (objEntId.Database)?

[_gile · Accepted solution]

It seems to me the code could be much simpler.

private static void PutXdataDate(ObjectId entId, string appName, string jDate)
{
    var db = entId.Database;
    using (var tr = new OpenCloseTransaction())
    {
        var regAppTable = (RegAppTable)tr.GetObject(db.RegAppTableId, OpenMode.ForRead);
        if (!regAppTable.Has(appName))
        {
            regAppTable.UpgradeOpen();
            var regApp = new RegAppTableRecord();
            regApp.Name = appName;
            regAppTable.Add(regApp);
            tr.AddNewlyCreatedDBObject(regApp, true);
        }

        var entity = tr.GetObject(entId, OpenMode.ForWrite);
        var xdata = new ResultBuffer(new TypedValue(1001, appName), new TypedValue(1000, "Jul_Date=" + jDate));
        entity.XData = xdata;
        tr.Commit();
    }
}

Yes the Working Database is not the same as the Object Database. That was the Problem. But Don't you have to Take care of Other registered apps so you don't overwrite them?

[GeeHaa]

By the Way I'm amasutti. I don't know why it didn't log me in by my Handle.

[GeeHaa]

The only other problem I'm having is, I get a file error saving. Can you tell me what I'm doing wrong.

using (Database acCurDB = new Database(false, true))
                    {
                        acCurDB.ReadDwgFile(GlobalVariables.listOfFiles[x], FileOpenMode.OpenForReadAndWriteNoShare, true, "");
                        using (Transaction acTrans = acCurDB.TransactionManager.StartTransaction())
                        {
}
                            acCurDB.SaveAs(GlobalVariables.listOfFiles[x], DwgVersion.Newest);

You can try the code I posted. It will only overwrite the xdata for the specified application (if any).

Never mind I figured it out. I needed to use the Overload that saved a Bak file as well.
