Modifying TextEditorSelection.Language Issue

drewj — Tue, 27 Feb 2018 18:49:30 GMT

This is a follow up to this question yesterday:

https://forums.autodesk.com/t5/net/modifying-characterset-property-of-mtext-object/td-p/7810356

Why is it that I can change the string in the MText with

MText mtext = (MText)tr.GetObject(id, OpenMode.ForWrite);
TextEditor textEditor = TextEditor.CreateTextEditor(mtext);
textEditor.SelectAll();
TextEditorSelection sel = textEditor.Selection;

sel.InsertString("Some New Text");

which works OK, however if I change the Language I get eInvalidInput

sel.Language = (int)System.Windows.Forms.VisualStyles.TextMetricsCharacterSet.Russian;

I am obviously misunderstanding something basic here, can anyone give me a pointer into the correct direction?

Thanks,

Drew

See the documentation for InsertString()

When you use this method, it invalidates the current selection.

I have been doing one or the other, so in the case of changing the Language I am not using the InsertString, so that shouldn't be a problem right?

See the docs >here<

According to that, eInvalidInput could be raised if the language isn't supported.

You can use the CanSupportLanguage() method to check if the selection supports a given language.
