Description
This method creates and returns a syntax element that corresponds to a conditional (if ... then or if ... then ... else) statement statement. For example:
JavaScript, JScript
if (! Success)
Log.Error("Checkpoint failed.");
Python
if not Success:
Log.Error("Checkpoint failed.")
VBScript
If (Not Success) Then
Call Log.Error("Checkpoint failed.")
End If
DelphiScript
if not Success then
Log.Error('Checkpoint failed.');
C++Script, C#Script
if (! Success)
Log["Error"]("Checkpoint failed.");
After you have created the conditional syntax element, use its Condition property to specify the condition to be tested. To specify the statement(s) to be executed if the condition evaluates to True, use the TrueSyntax property. If you need to execute some statement(s) when the condition is False, specify the corresponding syntax element in the FalseSyntax property.
Declaration

Applies To
The method is applied to the following object:
Result Value
An IfSyntax object that corresponds to a conditional statement.
Example
The following example generates the assignment statement given in the Description section and displays it in a message box:
JScript
function ShowIfThenStatement()
{
var oVarName = Syntax.CreateInvoke();
oVarName.InvokeName = "Success";
oVarName.IsProperty = true;
var oCondition = Syntax.CreateCondition();
oCondition.OperatorType = oCondition.otNot;
oCondition.Right = oVarName;
var oMethodCall = Syntax.CreateInvoke();
oMethodCall.ClassValue = "Log";
oMethodCall.InvokeName = "Error";
oMethodCall.IsProperty = false;
oMethodCall.AddParameter("Checkpoint failed.");
var oIf = Syntax.CreateIf();
oIf.Condition = oCondition;
oIf.TrueSyntax = oMethodCall;
var strCode = Syntax.GenerateSource(oIf);
aqDlg.ShowMessage(strCode);
}
VBScript
Sub ShowIfThenStatement
Dim oVarName, oCondition, oMethodCall, oIf, strCode
Set oVarName = Syntax.CreateInvoke
oVarName.InvokeName = "Success"
oVarName.IsProperty = True
Set oCondition = Syntax.CreateCondition
oCondition.OperatorType = oCondition.otNot
oCondition.Right = oVarName
Set oMethodCall = Syntax.CreateInvoke
oMethodCall.ClassValue = "Log"
oMethodCall.InvokeName = "Error"
oMethodCall.IsProperty = False
oMethodCall.AddParameter "Checkpoint failed."
Set oIf = Syntax.CreateIf
oIf.Condition = oCondition
oIf.TrueSyntax = oMethodCall
strCode = Syntax.GenerateSource(oIf)
aqDlg.ShowMessage strCode
End Sub
