What should you know before start with visual basic language?

Answer 1

My answer to this question would be go and learn QBASIC programming language, first; as it is the 'base' language which underlies most Microsoft BASIC related programming languages, including:-

Visual BASIC

VBScript/Visual BASIC Script

VBA/Visual BASIC for Applications

VB.NET/Visual BASIC.NET

-etc.

QBASIC, however, doesn't use objects to do programming with...like these other languages do; and, I personally do believe this fact makes it quicker, simpler, far more straight forwards, and, easier to learn. Then, once you've already learned the QBASIC programming fundamentals, such as:-

String literals/Numeric literals

Variables: String, Numeric: integer/Single/Double

Variable scope: Global/Local

Loops: Do/Loop, For/Next

If/Then/Elseif/Else/End if

Select Case/End Select

Logical operators/Relational Operators/Mathematical Operators

Sub/End Sub,Function/End Function

Filing: Serial/Binary

Graphics; Text based/Drawing based/Screenmodes/Colors

Sounds

-etc.

Then, you can consider expanding your knowledge by moving on to go study more advanced programming languages; like those already mentioned up above.

Of course, it is possible to go and learn Visual BASIC without having to go learn QBASIC, first; indeed, many VB programmers have succeeding in doing things exactly that way.

But, having learned QBASIC, first, myself; and, then, next, moved on to go learn Visual BASIC; I can honestly say that QBASIC certainly paved my way...thus, making learning VB feel like being a total BREEZE...! When I look back, I realise that if I had not gone and learned QBASIC, first; then, I might have had a really difficult time with struggling to go learn VB, afterwards.
