    End If  
    MsgBox("This variable has been called: " & _

        System.Int32 int32;  
        int32 = System.Int32.Parse((string)  
        globals["GlobalsExample"]);  
        int32++;

    }  
    else  
    {  
        // Counter has never been set, so create and initialize it.  
        globals["GlobalsExample"] = 1.ToString();  
        globals.set_VariablePersists("GlobalsExample", true);  
    }  
    System.Windows.Forms.MessageBox.Show("This variable has been called:   
    " + globals.VariableValue["GlobalsExample"] + " times.");  
}

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."
