Document Summary
Visual studio: good at user interface without having to write code. Event drive programming: user interface is sitting there until someone does something: ex. Touching the screen, clicking: responds to some event. Event handler: some program section/module that handles a particular event. Add event: if click on picture, double click on picture, new tab form 1. vb. Event handler that handles event: vs automatically creates end sub, pick what changing, give command. Mouse enter: when pointer enters into picture box. Put quotes around it string constant: sequence of characters. Without quotes there would be an error message: in red then show you string constant. Build errors: syntax errors; couldn"t build a logical problem. To get line numbers: tools, pull down menu, text editor, specific one for basic. Check line number: helpful if have multiline program it shows you where your error is. Word wrap shows on the beginning of next line: lines matter in vb, one line one statement.
