You need to read and study the ObjectARX documentation, because anyone that does that, should know and understand that an ObjectId is not a permanent reference that you can use across different AutoCAD sessions.
Try not to depend on folks here to teach you what you can easily learn by studying the docs and the samples.
The only permanent way to reference to an object in a drawing file, is by using its Handle.

Hi,
I want to change an Mtext in an extern DWG.
I Tried it with this code:
Database db = new Database(false, false);
db.ReadDwgFile("C:\\Zeichnung123.dwg", System.IO.FileShare.ReadWrite, true, "");
Autodesk.AutoCAD.DatabaseServices.TransactionManager tm = db.TransactionManager;
Autodesk.AutoCAD.DatabaseServices.Transaction tr = tm.StartTransaction();
//texte.Contents = FormSprache.ShowDialog("");
//PromptPointOptions prPO = new PromptPointOptions("\nAn welche Stelle soll das Textfeld");
PromptStringOptions pso1 = new PromptStringOptions("Geben Sie die ObjectId ein:");
PromptResult presult = ed.GetString(pso1);
if (presult.Status == PromptStatus.OK)
{
String stringobjectid = presult.StringResult.ToString();
ObjectId test = new ObjectId(2130268248);
test.GetObject(OpenMode.ForWrite, false);
MText texte = (MText)tm.GetObject(test, OpenMode.ForWrite);
texte.Contents = "blablub";
tr.Commit();
MeineForms.MessageBox.Show(texte.ObjectId.ToString());
}
if i run the code then Autocad says that he not found the ObjectId.
But if i open the dwg and try the same on the activedocument database it is successfully.
I hope anybody can help me.
Maybe in you can answer me in german 🙂
Greetings Steffen
