MsgBox Designer - Copy Text Box value to Clipboard

Attached is a library that contains a MsgBox Designer (feel free to use it). The start procedure is MsgBoxDialog.
What I want is to add a “Copy code to Clipboard” button. When I click on the button, the text from the txtCode multiline control should be copied to the Clipboard.
I’ve tried everything I know and everything Gemini + ChatGPT told me, but nothing works.

Where is your problem: get text or copy to clipboard

May I suggest google …

are my first two hits…

Please attach a document of an odf type containg your code. A replacement for the Sub you don’t yet get to work may simply tell “Here I am!”
This way a contributor can much more easily (or at all) see what you actually try to achieve than by studying files from your profile.
