Modifying CharacterSet Property of MText Object

[drewj]

Is it possible to modify the CharacterSet of a MTEXT element?

You can modify it on the ribbon (see attached CharacterSet image) but I the only reference I can see for it is that it is readonly on the Font rather than on the individual mtext element (see FontCharacterSet image).

Regards,

I'm pretty sure that the way to do this is via the TextEditor class. You call TextEdtior.CreateTextEditor() passing in the MText.

Then, you establish the selection or range of text that you want to modify (or use SelectAll() to modify the entire MText), then you use the Language property of the TextEditorSelection object returned by the TextEditor's Selection property. The value of the Language property is an int, which can be cast to/from System.Windows.Forms.VisualStyles.TextMetricsCharacterSet.

That's exactly the type of push in the right direction I was looking for, thanks. I will report back if I get it working.

Cheers,

Whoops, let me check that Language you suggested. I missed that, nearly there.

Thanks for the help, this code accomplished the requirement:

public static void SetTextToModifiedCharacterSet(Document document)
{
Database db = document.Database;
Editor ed = document.Editor;
TypedValue[] tvs = new[]
{
new TypedValue(0, "MTEXT"), // only MText
new TypedValue(410, "Model") // in model space
};
SelectionFilter filter = new SelectionFilter(tvs);
PromptSelectionResult selection = ed.SelectAll(filter);
if (selection.Status != PromptStatus.OK)
return;
using (Transaction tr = db.TransactionManager.StartTransaction())
{
foreach (SelectedObject obj in selection.Value)
{
ObjectId id = obj.ObjectId;
if (id.ObjectClass.DxfName == "MTEXT")
{
MText mtext = (MText)tr.GetObject(id, OpenMode.ForWrite);
TextEditor textEditor = TextEditor.CreateTextEditor(mtext);
textEditor.SelectAll();
TextEditorSelection sel = textEditor.Selection;
sel.Language = (int)System.Windows.Forms.VisualStyles.TextMetricsCharacterSet.Russian;
textEditor.Close(TextEditor.ExitStatus.ExitSave);
}

}
tr.Commit();
}
}
