How are global variable different from local variable in Visual BASIC?
A global variable is available for use throughout the program. It is normally declared outside any procedure. A local variable is only available for use in the procedure it was declared in. Most variables are local, but there will be occasions when you want different procedures to be able to use the same variable. This is when you use a global variable.
How many variable in visual basic?

What is long in visual basic?
Long is a kind of data type that can contain any number from 9,223,372,036,854,775,808 to 9,223,372,036,854,775,807. This means that if you declare a variable or array as a "long", then it will be able to contain these numbers.

What is class varient?
Variant is a data type in certain programming languages, particularly Visual Basic and C++ when using the Component Object Model.In Visual Basic (and Visual Basic for Applications) the Variant data type is a tagged union that can be used to represent any other data type (for example, integer, floating-point, single- and double-precision, object, etc.) except fixed-length string type and record types. In Visual Basic any variable, not declared explicitly or the type of which is not declared explicitly, is taken to be a variant.

Is there a way to use a variable to declare the size of an array in true basic?
! variable to declase the size of an array in True Basic ! set up a dummy value for array - any initial value > 0 is fine. DIM array$(999) ! ask the user for the length of the array INPUT PROMPT "Enter array size " :size ! resize the array with user defined length MAT REDIM array$(size) ! program end END

Explain how Multidimensional Arrays are used in a Visual Basic application?
Creating a Visual Basic Multidimensional Array Declaring a multidimensional array requires both the number of rows and columns to be defined when the array is created. As with standard arrays, multidimensional arrays are declared using the Dimkeyword: Dim strBooks(4, 2) As String The above Visual Basic code excerpt creates a two dimensional String array of 5 rows and 2 columns. Assigning Values to Multidimensional Array Values are assigned to array elements by specifying the index into each dimension. For example, in a two dimensional array, 0, 0 will references the element in the first column of the first row of the array. The following code initializes each element of our array: Dim strBooks(4, 1) As String strBooks (0, 0) = "Learning Visual Basic" strBooks (0, 1) = "John Smith" strBooks (1, 0) = "Visual Basic in 1 Week" strBooks (1, 1) = "Bill White" strBooks (2, 0) = "Everything about Visual Basic" strBooks (2, 1) = "Mary Green" strBooks (3, 0) = "Programming Made Easy" strBooks (3, 1) = "Mark Wilson" strBooks (4, 0) = "Visual Basic 101" strBooks (4, 1) = "Alan Woods" The above example creates a two dimensional array of 5 rows (remember that indexing starts at 0 so this array have elements from 0 to 4 inclusive) and two columns. Column 1 is the book title and column 2 the author.Answerer 1 Multidimensional arrays are used as follows:-Dim a(m,n) as integerfor putting valuefor i = 1 to mfor j = 1 to na(i , j) = val(inputbox("Enter the value"))s = s & a(i , j) & " "next js = s & vbcrlfnext i
