Debugger3.ExecuteStatement Method (String, Int32, Boolean)

Executes the specified statement. If the TreatAsExpression flag is true, then the string is interpreted as an expression, and output is sent to the Command Window.

Namespace:  EnvDTE90
Assembly:  EnvDTE90 (in EnvDTE90.dll)

Syntax

'Declaration
Sub ExecuteStatement ( _
    Statement As String, _
    Timeout As Integer, _
    TreatAsExpression As Boolean _
)
void ExecuteStatement(
    string Statement,
    int Timeout,
    bool TreatAsExpression
)
void ExecuteStatement(
    [InAttribute] String^ Statement, 
    [InAttribute] int Timeout, 
    [InAttribute] bool TreatAsExpression
)
abstract ExecuteStatement : 
        Statement:string * 
        Timeout:int * 
        TreatAsExpression:bool -> unit 
function ExecuteStatement(
    Statement : String, 
    Timeout : int, 
    TreatAsExpression : boolean
)

Parameters

  • Timeout
    Type: System.Int32
    The timeout period, in milliseconds.
  • TreatAsExpression
    Type: System.Boolean
    true if the string is to be interpreted as an expression; otherwise false.

Debugger2.ExecuteStatement(String, Int32, Boolean)

Remarks

ExecuteStatement executes the specified statement. A statement differs from an expression in that a statement can consist of one or more expressions. Therefore, typically no value can be associated or returned by statement execution.

Some languages, such as Visual Basic, support a language syntax that relies on the context in which a statement appears to indicate how the statement is evaluated. For example, if your Visual Basic code has statement, a = 1, it is interpreted as an expression if the code appears inside an If…Then statement. It is interpreted as a statement if it appears alone on a line. The expression tests a against the value of 1, the statement will set a equal to 2. See the following example.

Output from this method is sent to the Command Window.

Examples

The following example shows how to use the ExecuteStatement method.

To test this method:

  1. Set the breakpoint in the target application after a value is assigned to the variable.

  2. Run the target application in the debug mode.

  3. When the application stops at the breakpoint, run the add-in.

  4. The value of the variable changes to a new value.

public static void ExecuteStatement(EnvDTE80.DTE2 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("ExecuteStatement 
    Method Test");
    owp.Activate();

    EnvDTE90.Debugger3 debugger = (EnvDTE90.Debugger3)dte.Debugger;
    debugger.ExecuteStatement("tempC = 100.0", 100, false);
    owp.OutputString("The new value of tempC variable is: " + 
                     debugger.GetExpression("tempC", false, 1).Value);
}
' The following executes a statement, effectively
' setting a to the value of 2.
Sub SetVariable()
    DTE2.Debugger.ExecuteStatement("a = 2", -1, False)
End Sub

' The following tests the value of a against
' the value of 2.  False is displayed in the command window.

Sub TestVariable()
    DTE2.Debugger.ExecuteStatement("a = 2", -1, True)
End Sub
