Cycling through all text (interop)

[Anonymous]

Hi,
I am using C# an interop. I need to cycle through all text in an autoCAD 2D drawing, and search for a certain string.
How do i do this?
I imagined just creating a selection, and doing a foreach AcadText in selection.
This, however, gives me a cast exception.
Can i narrow my selection down to just selecting text?
If so, how do i do that?

This NG is primaryly for .NET API. So even you use C#, COM interop questions may more likely get answered in VBA NG.

That said, you can just open AutoCAD VBA IDE, in Objet Browser, find AcadSelectionSet.Select() method, and click "?" button on the Object Browser to read how to use filter in the AcadSelectionSet.Select() method to only select entities of your choice in the VBA/COM API document. The sample code there is simple and straightforward.

Thanks, that was my mistake 🙂

I actually did solve it last night though. Apparently there is both a MText and a Text, and they cannot be cast to eachother.
