This filtering function returns True if the member name begins with the character passed as its second argument. Note: it requires Imports System.Reflection

Accept only properties and methods whose return value matches the Type passed as the second argument. Note: it requires Imports System.Reflection

Reflection makes it easy to invoke a method (or assign a field or a property) by its name. For example, suppose you have the following classes: Class Person Event PropertyChanged(ByVal propertyName As String, ByVal newValue As Object) Dim m_Name As String Property ...

You can use the technique for an "undo" menu/toolbar option. Use a collection instead of a listbox to reduce overhead. Support for both LIFO and FIFO is also included: ...

An object that want to support cloning should implement the ICloneable interface. This interface exposes only one method, Clone, which returns a copy of the object. The ICloneable specifics don't specify whether the object that the Clone method returns is a shallow copy or a deep copy.

The simplest way to create a generic deep copy routine, that is a procedure that can create a true, distinct copy of an object and all its dependent object, is to rely on the serialization features of the .NET framework. Function CloneObject(ByVal obj As Object) As Object ...

As strange as it may seem, C++ doesn't allow you to re-open a namespace using a qualified name; you can re-open it only by using its nested name. For example, the following program defines a ...

Use this function to read a number decimal symbol from regional ...

Control arrays are odd beasts in that they can have missing elements. The simplest way to iterate a control array uses this ...

When you use the Add-Ins project template to build your own add-ins, the description of the add-in appearing in the Add-Ins Manager window is always "My Addin." It isn't immediately clear how you can ...

The library defines the following open modes and file ...

-------------------------------------------------- The CSTACK class Usage: Dim st As New CStack push two values on the stack st.Push 1234 st.Push 4567 display number of elements in the stack Debug.Print "Count = " & st.Count peek at the element on top of stack Debug.Print "Peek = " & st.

---------------------------------------------- HASHTABLE class module This class implements a hashtable, a structure that offers many of the features of a collectior or dictionary, and is often even faster than the built-in collection. NOTE: must make Item the default member, using the ...

------------------------------------------------- LINKED LIST class module This class implements a linked list structure, where you can store values (appending them after the last element or inserting them at given indexes), remove them, and visit them using recordset-like methods such as ...
