array so that it is variable in size. First, you do not have to specify the size when declaring an arrayDim VarName ()You can use the ReDim statement to set or reset the size of an array before the first use, and at any time thereafterReDim [Preserve] varname (subscripts) [, ...]The keyword Preserve makes VBScript keep existing data in a resized array. (If the new array is shorter than the original, the extra elements at the end are removed). If ther

The VBScript language provides two statements and an object to handle "Run-time errors", such as the next, 1.On error Resume Next statement, 2.On error Goto 0 statement, 3.Err object, below we will discuss in detail. If the On Error statement is not used, any run-time error is fatal, that is, the result will cause an error message to be displayed and the operation aborted. A "allowed" error handler is a handler that is opened by the On Error statemen

Repeating code with loops Loops are used to repeatedly execute a set of statements. Loops can be grouped into three categories: a class that repeats a statement before the condition becomes False, a class that repeats the statement before the condition becomes True, and another class repeats the statement at a specified number of times. The following looping statements can be used in VBScript: Do ... Loop: loops when (or until) the condition is True.

Busy looking for a job until the weekend is free. Now to continue the design of our VBScript class. We've designed a simple date class the last time, but there are some On the issue. Now we're going to change our design for these issues. The problem we have to solve this time is: 1, if the user specified classdate is not a date type, then the date will become January 1, 1900; 2. If more than one date is displayed, the name of the form object cannot be

Using Loop statements Loops are used to repeatedly execute a set of statements.

Description Property Returns or sets a descriptive string associated with the error. object.Description [= stringexpression] Parameters Object The Err object. stringexpression A string expression containing the error description.

declaring a constant in this way, if the public or Private keyword is used, the keyword is valid for all constants in the row. variables, user-defined functions, or VBScript intrinsic functions (such as Chr) cannot be used in a constant declaration. By definition, they cannot be constants. In addition, you cannot create constants from an expression that contains an operator, that is, only simple constants are allowed. A constant declared in a Sub or
