Multiline Editbox

How can I make an edit box which can hold multiple lines of text?

To Chorv

Create an edit box on your dialog of ample size.
Right click on the edit box and go into the properties.
In the Styles tab check multiline, vertical scroll, want return

I hope this helps

Check the multiline property for the edit in the dialog editor or of you create it dinamically add the ES_MULTILINE style.
Let me know if this works fine for you.
Best regards,
