VBScript Elements, Objects, and Variables
The following tables detail VBScript elements, objects, and variables.
Operators
The following table contains the VBScript operators:
Operator |
Description |
And |
Performs a logical conjunction on two expressions. |
Or |
Performs a logical disjunction on two expressions. |
Not |
Performs a logical disjunction on two expressions. |
Mod |
Divides two numbers and returns only the remainder. |
Reserved symbols
The following table contains the VBScript reserved symbols and how to use them:
Keyword |
Description |
True |
The True keyword has a value equal to -1. |
False |
The False keyword has a value equal to 0. |
Nothing |
Used to disassociate an object variable from any actual object. To assign Nothing to an object variable, use the Set statement, for example:
Several object variables can refer to the same actual object. When Nothing is assigned to an object variable, that variable no longer refers to any actual object. When several object variables refer to the same object, memory and system resources associated with the object to which the variables refer are released only after all of them have been set to Nothing, either explicitly using Set, or implicitly after the last object variable set to Nothing. |
Null |
The Null keyword is used to indicate that a variable contains no valid data. |
vbCr |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbCrLf |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbLf |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbFormFeed |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbNewLine |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbNullChar |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbTab |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbVerticalTab |
When you call print and display functions, you can use the following constants in your code in place of the actual values. |
vbBlack |
Black. Value = 0x0. |
vbRed |
Red. Value = 0xFF. |
vbGreen |
Green. Value = 0xFF00. |
vbYellow |
Yellow. Value = 0xFFFF. |

Report Field Names
Names of Field objects are evaluated and return a reference to the object, so you can access the field's properties. The default property for the Field object is Value, so by itself the field name returns the field's current value. For example:
MyField.BackColor = RGB(200,250,100)
MyField.Font.Size = 14
MyField * 2 ' (same as MyField.Value * 2)
• C#
MyField.BackColor = RGB(200,250,100);
MyField.Font.Size = 14;
MyField * 2; // (same as MyField.value * 2)
Note: If you give a report field the same name as a database field, you won't be able to access the report field.
Report Section Names
Names of Section objects are evaluated and return a reference to the object, so you can access the section's properties. The default property for the Section object is Name. For example:
If Page = 1 Then [Page Footer].Visible = False
• C#
if (Page = 1)
{
[Page Footer].Visible = false;
}
Database Field Names
Names of fields in the report's dataset source are evaluated and return the current field value. If a field name contains spaces or periods, it must be enclosed in square brackets. For example:
OrderID
UnitsInStock
[Customer.FirstName]
[Name With Spaces]
Report Variables
Page
The page variable returns or sets the value of the Page property. This property is initialized by the control when it starts rendering a report, and is incremented at each page break. You may reset it using code. For example:
If Country <> LastCountry Then Page = 1
LastCountry = Country
• C#
if (Country != LastCountry)
{
Page = 1
}
else
{
LastCountry = Country;
}
Pages
The pages variable returns a token that gets replaced with the total page count when the report finishes rendering. This is a read-only property that is typically used in page header or footer fields. For example:
"Page " & Page & " of " & Pages
• C#
"Page " + Page + " of " + Pages;
Report Object
The report object returns a reference to the control object, so you can access the full C1Report object model from your scripts and expressions. For example:
"Fields: " & Report.Fields.Count
• C#
"Fields: " + Report.Fields.Count;
Cancel
Set Cancel to True to cancel the report rendering process. For example:
If Page > 100 Then Cancel = True
• C#
if ( Page > 100 )
{
Cancel = true;
}
