Function EditExpression ( _
parentWindow As IWin32Window, _
dtsContainer As DtsContainer, _
expressionType As Type, _
ByRef expression As String _
) As Boolean
bool EditExpression (
IWin32Window parentWindow,
DtsContainer dtsContainer,

bool EditExpression (
IWin32Window^ parentWindow,
DtsContainer^ dtsContainer,
Type^ expressionType,
String^% expression

boolean EditExpression (
IWin32Window parentWindow,
DtsContainer dtsContainer,

JScript does not support passing value-type arguments by reference.
Parameters
- parentWindow
The IWin32Window handle to the Windows form from which the Expression Builder dialog box is invoked.
- dtsContainer
The DtsContainer that defines the scope for package variables that can be used in the expression.
- expressionType
The Type of the return type of the expression.
- expression
A string that is passed by reference and represents the expression.
Return Value
true if the expression has changed; otherwise, false.
Remarks
You can use the EditExpression method whenever you want to let the user create or modify an expression. However, to modify a property expression, the EditPropertyExpression method might be more useful. The EditPropertyExpression method determines the return type of the expression from the data type of the property and assigns the expression to the property for you.
