For some logging ouput, I have a Windows.Forms.Textbox which is updated via
TB.AppendText("some new text");
The method is hungry at redrawing the text field with >2000 lines inside, however it feels faster than with TB.text += 'some new text.
What should I use instead of Textbox to get quick inserts with low CPU load and fast refresh? I thought about Listbox but not sure if it will fit (however, DebugView’s ‘listbox’ seems to be able to handle billions of lines without heavy load).
A ListBox or ListView would be much better suited for what you are proposing.
And if size becomes an issue, you can use ListView’s VirtualMode to only load the items as needed, based on the user’s scrolling.
