VBScript Reference Manual InduSoft Web Studio arglist List of variables representing arguments that are passed to the Property Set procedure when it is called. Commas separate multiple arguments. In addition, the Property Set procedure will always have one more argument than its corresponding Property Get procedure. That argument is the object being assigned to the property. reference Variable containing the object reference used on the right side of the object reference assignment. statements Any group of statements to be executed within the body of the Property Set procedure. Remarks Property Set is very similar to Property Let except that the Property Set procedure is used exclusively for object-based properties. If not explicitly specified using either Public or Private, Property Set procedures are public by default, that is, they are visible to all other procedures in your script. The value of local variables in a Property Set procedure is not preserved between calls to the procedure. You can't define a Property Set procedure inside any other procedure (e.g. Function or Property Let). The Exit Property statement causes an immediate exit from a Property Set procedure. Program execution continues with the statement that follows the statement that called the Property Set procedure. Any number of Exit Property statements can appear anywhere in a Property Set procedure. Like a Function and Property Get procedure, a Property Set procedure is a separate procedure that can take arguments, perform a series of statements, and change the value of its arguments. However, unlike a Function and Property Get procedure, both of which return a value, you can only use a Property Set procedure on the left side of an object reference assignment (Set statement). Note: Every Property Set statement must define at least one argument for the procedure it defines. That argument (or the last argument if there is more than one) contains the actual object reference for the property when the procedure defined by the Property Set statement is invoked. That argument is referred to as reference in the preceding syntax. See Also Property Get, Property Let Example Class FileHelper Private myFSO ‘Define a variable to be used for an object Public Property Set FSO(objFso) ‘Set Property Set myFSO = objFso ‘Defines the object End Property End Class 188 InduSoft, Ltd.
InduSoft Web Studio VBScript Reference Manual Public Description Declares public variables and allocates storage space. Declares, in a Class block, a public variable. Usage Public varname[([subscripts])][, varname[([subscripts])]] . . . Arguments varname Name of the variable, following standard variable naming conventions subscripts Dimensions of an array variable, up to 60 multiple dimensions may be declared. The subscripts argument uses the following syntax: Upper[,upper]… The lower bound of an array is always zero. Returns N/A Remarks Public statement variables are available to all procedures in all scripts. Note: This is subject to InduSoft restrictions contained in IWS. A variable that refers to an object must be assigned an existing object using the Set statement before it can be used. Until it is assigned an object, the declared object variable is initialized as Empty. You can also use the Public statement with empty parentheses to declare a dynamic array. After declaring a dynamic array, use the ReDim statement within a procedure to define the number of dimensions and elements in the array. If you try to re-declare a dimension for an array variable whose size was explicitly specified in a Private, Public, or Dim statement, an error occurs. See Also Private Example Public MyNumber ‘Public Variant variable Public MyArray(9), MyVar ‘Multiple Public declarations Randomize Description Initializes the random number generator. Usage Randomize(number) Arguments number The number argument can be any valid numeric expression Returns N/A Remarks Randomize uses number to initialize the Rnd function's random-number generator, giving it a new seed value. If you omit number, the value returned by the system timer is used as the new seed value. If Randomize is not used, the Rnd function (with no arguments) uses the same number as a seed the first time it is called, and thereafter uses the last generated number as a seed value. To repeat sequences of random numbers, call Rnd with a negative argument immediately before using Randomize with a numeric argument. Using Randomize with the same value for number does not repeat the previous sequence See Also Rnd Example Dim MyValue, Response Randomize ‘Initialize random number generator Do Until Response = vbNo MyValue = Int((6*Rnd) +1) ‘Generate random value between 1 and 6 MsgBox MyValue ‘Print it Response = MsgBox (“roll again? “. vbYesNo) Loop InduSoft, Ltd. 189
