虽然vb可以把资源存在*.RES的资源文件里，一起编译成exe。但如果要换肤、多语言支持，显然DLL更方便
如何把图片、图标、自定义资源存放在DLL里面？下面我Step by Step教大家。
VB只能创建Activex DLL，所以用VC++创建纯正的DLL，这样的DLL无需注册（基于COM的才要注册）。下面以VC++ 6.0为例（VC++ 2005也差不多）。
1.打开VC++ 6.0,文件->新建
再选择“一个简单的DLL工程”，完成。
新建一个资源脚本（*.rc）,即文件->新建...
在resource.rc单击右键，右键->属性，取消“启动MFC特性”，再右键->引入，添加资源
引入后，右键相应资源的属性，重命名ID为100~32767之间的数值。
按 工程->设置
修改参数堆栈方式为__stdcall（VB用的是这种），这是一个纯资源DLL，没有函数供VB调用没什么必要改
注意橙色区域选项要一致，在红色区域加上/noentry，如果你是新手，我教你就在参数最后面打个空格，再输入/noentry
这个参数表示DLL没有入口，本来在纯资源DLL就不打算写函数嘛
最后选择Release版本编译，有3种方法（VC++ 2005 有个配置管理器）
（1）在vc右上角菜单栏或工具栏的空白处右键，选上Build项，使build工具栏可见，在Build工具栏上就可以选择工程的Release版本。
（2）组建->批组建，在弹出的对话框中选择编译哪个版本，或者两个版本都编译。
（3）组建->配置，移除Win32 Debug。
组建->组建[myDLL.DLL],在Release文件夹下就生成了myDLL.DLL。PS:debug模式编出来的DLL很肥
2.在VB中新建工程，创建按钮Command1、Command2。图片框Picture1
位图 资源ID：100
自定义资源"WAVE" 资源ID：101
form1.frm代码：
Option Explicit
Private Sub Command1_Click()
Picture1.Picture = LoadPicture("") '清空图片框控件
load_pic (100)
End Sub
Private Sub Command2_Click()
load_sound (101)
End Sub
Module1.bas代码：
