Indicates whether the specified value in an expression is valid.
Namespace: EnvDTE
Assembly: EnvDTE (in EnvDTE.dll)
Syntax
'Declaration
ReadOnly Property IsValidValue As Boolean
bool IsValidValue { get; }
property bool IsValidValue {
bool get ();
}
abstract IsValidValue : bool with get
function get IsValidValue () : boolean
Property Value
Type: System.Boolean
A Boolean value.
Remarks
Returns true if the value in the expression is valid; otherwise, it returns false.
Examples
The following example demonstrates how to use the IsValidValue property.
To test this property:
Set a breakpoint in your target application.
Run the target application in the debug mode.
When the application stops at the breakpoint, run the add-in.
public static void IsValidValue(DTE dte)
{
// Setup debug Output window.
Window w = (Window)dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput);
w.Visible = true;
OutputWindow ow = (OutputWindow)w.Object;
OutputWindowPane owp = ow.OutputWindowPanes.Add("IsValidValue property: ");
owp.Activate();
EnvDTE.Expression exp = dte.Debugger.GetExpression("tempC", true, 1);
if(exp.IsValidValue)
owp.OutputString("The specified value in an expression is valid.");
else
owp.OutputString("The specified value in an expression is invalid.");
}
Shared Sub IsValidValue(ByRef dte As EnvDTE.DTE)
Dim exp As EnvDTE.Expression = dte.Debugger.GetExpression("tempC", True, 1)
If exp.IsValidValue Then
MessageBox.Show("The specified value in an expression is valid.", _
"Expression Test - IsValidValue Property")
Else
MessageBox.Show("The specified value in an expression is invalid.", _
"Expression Test - IsValidValue Property")
End If
