VB Programming, what is VB Programming?

Simple! 1. Define the array a(4,4).

2. In the loop, use int(240+rnd(325-240)) to generate random numbers and assign them to an array, and judge whether it is less than 300, when it is less than 300, add up, and record the number.

3. When you are done, you can get the sum average.

4. The diagonal is directly judged by the bubble method. And there are rules to follow.

private sub command1_click()

dim a(4, 4) as string, str() as string, tmp as string, sumstr as long, count as integer

dim max1 as integer, tmp1 as integer, max2 as integer

for i = 0 to 4

for j = 0 to 4

randomize

a(i, j) = int(rnd * 85 + 240)

i * 400

j * 200

a(i, j)

if val(a(i, j)) 300 then tmp = tmp & a(i, j) &"|"

next j

next i

str = split(tmp, "|")

Numbers less than 300:";

for i = 0 to ubound(str)

if str(i) <"" then str(i) &",";: count = count + 1

sumstr = val(str(i)) sumstr

vbcrlf & "Less than 300 and:" & sumstr

Less than 300 numbers average:" & sumstr / count

vbcrlf & "The first diagonal:";

max1 = val(a(0, 0))

for i = 0 to 4

a(" & i & "," & i & ")=" & a(i, i) &",";

if val(a(i, i)) max1 then tmp1 = val(a(i, i)):max1 = tmp1

vbcrlf & "First diagonal maximum:" & max1

vbcrlf & "Second diagonal:";

max2 = a(0, 4)

for i = 0 to 4

a(" & i & "," & 4 - i & ")=" & a(i, 4 - i) &",";

if val(a(i, 4 - i)) max2 then tmp1 = val(a(i, 4 - i)):max2 = tmp1

next i

vbcrlf & "Second diagonal maximum:" & max2

end sub

Visual Basic (VB) is an event-driven programming language developed by Microsoft that includes environments. It is derived from the basic programming language. VB has a graphical user interface (GUI) and a rapid application development program (RAD) system, which can be easily used to connect to the database using DAO, RDO, ADO, or easily create ActiveX controls.

Programmers can easily quickly create an application using the components provided by VB.

visual basic .net (Yes.) A high-level language for multiple programming paradigms under the .NET framework.

It was introduced by Microsoft in 2002 as the successor to the original Visual Basic. Although since 2005, the language name in the ". .net" has been removed.

But in order to distinguish it from VB and previous versions of Visual Basic, Visual BasicThe name "net" is still used by the public to refer to VB and later Visual and C. The two main programming languages under the .NET Framework are designed to be called.

.NET Framework's class library resources, so the two languages have a high correspondence, data types, control structures and language characteristics are one-to-one correspondence, and it is easy to translate the source ** from one language pair to another.

Visual Basic programming is the basic programming language.

With a graphical user interface (GUI) and rapid application development (RAD) system, VB can easily connect to databases using DAO, RDO, ADO, or easily create Active X controls for efficient generation of type-safe and object-oriented applications.

Programmers can easily build an application quickly using the components provided by VB.
