    VariableName As String _
) As Object
Object this[
    string VariableName
] { get; set; }
property Object^ default[String^ VariableName] {
    Object^ get (String^ VariableName);
    void set (String^ VariableName, Object^ value);
}

JScript does not support indexed properties.

Parameters

  • VariableName
    Type: System.String

    Required. A string representing the name of the variable to retrieve.

Property Value

Type: System.Object
An object representing the variable.

Remarks

If you attempt to retrieve a variable that does not exist, the variable is created with an empty value. If you attempt to set a variable that does not exist, it is created with the specified value.

Note

VariableValue name strings cannot contain space, colon (:), or period(.) characters. If a name has any of these characters, you get the error, "Value does not fall within expected range."

Examples

Sub OnAddinLoaded(ByVal dte As DTE)
    ' Count the number of times an add-in is loaded
    ' and store the value in the solution.
    Dim globals As Globals
    globals = dte.Solution.Globals
    If globals.VariableExists("AddinLoadCounter") Then
        ' The counter has already been set, so increment it.
        Dim int32 As System.Int32
        int32 = System.Int32.Parse(CStr(globals("AddinLoadCounter")))
        int32 += 1
        globals("AddinLoadCounter") = int32.ToString()
    Else
        ' Counter has never been set, so create and initialize it.
        globals("AddinLoadCounter") = 1.ToString()
        globals.VariablePersists("AddinLoadCounter") = True
    End If
    MsgBox("This add-in has been loaded: " & _
    globals.VariableValue("AddinLoadCounter") & " times.")
End Sub
void OnAddinLoaded(_DTE applicationObject)
{
    // Count the number of times an add-in is loaded
    // and store the value in the solution.
    Globals globals;
    globals = applicationObject.Solution.Globals;
    if(globals.get_VariableExists("AddinLoadCounter"))
    {
        // The counter has already been set, so increment it.
        System.Int32 int32;
        int32 = System.Int32.Parse((string)
        globals["AddinLoadCounter"]);
        int32++;
        globals["AddinLoadCounter"] = int32.ToString();
    }
    else
    {
        // Counter has never been set, so create and initialize it.
        globals["AddinLoadCounter"] = 1.ToString();
        globals.set_VariablePersists("AddinLoadCounter", true);
    }
    System.Windows.Forms.MessageBox.Show("This add-in has been loaded: 
    " + globals.VariableValue["AddinLoadCounter"] + " times.");
