        globals("GlobalsExample") = int32.ToString()  
    Else  
        ' Counter has never been set, so create and initialize it.  
        globals("GlobalsExample") = 1.ToString()

    End If  
    MsgBox("This variable has been called: " & _  
    globals.VariableValue("GlobalsExample") & " times.")

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