Public Shared Function ReadProcessMemory(ByVal hProcess As IntPtr, _
ByVal lpBaseAddress As IntPtr, _
Out() ByVal lpBuffer() As Byte, _
ByVal dwSize As Integer, _
ByRef lpBytesRead As Integer) As Boolean
End Function
Dim buffer(3) As Byte()
ReadProcessMemory(hProcess, H274A024, buffer, buffer.Length, bytesRead)
如果要读不到，用逐步调试看看hProcess有没有问题，还要检查H274A024是否存在。

vb.net和vb编程的区别
vb.net是完全面向对象的语言，支持面向对象的四个基本属性:抽象,继承，多态，封装，但vb是面向过程的语言，它只支持部分面向对象的内容像多态，接口等。从 VB 7.0 之后的版本俗称 VB.NET，来源于微软的.NET战略，到现在为止有三个版本
VB 7.0 即VB 2002，对应.NET Framework 1.0的版本
VB 7.1 即VB 2003，对应.NET Framework 1.1的版本
VB 8.0 即VB 2005，对应.NET Framework 2.0的版本
除了语法和使用习惯的继承，VB 6.0之前的版本和VB 7.0之后的版本完全没有联系，几乎没有相同之处，两种不同体系的语言
VS2010中的vb是vb。net吗？求相关教程。
VS2010中的VB就是VB.NET。
安装了VS可从软件的帮助入口获取来自微软MSDN的丰富在线帮助文档。它就是具有相关教程内容的网络资源。
Microsoft Visual Studio 2010，Visual Studio是微软公司推出的开发环境，是目前最流行的Windows平台应用程序开发环境。Visual Studio 2010版本于2010年4月12日上市，其集成开发环境（IDE）的界面被重新设计和组织，变得更加简单明了。Visual Studio 2010同时带来了NET Framework 4.0、Microsoft Visual Studio 2010 CTP( Community Technology Preview--CTP)，并且支持开发面向Windows 7的应用程序。除了Microsoft SQL Server，它还支持 IBM DB2和Oracle数据库。
VB.NET即Visual Basic.NET是基于微软.NET Framework之上的面向对象的编程语言。
其在调试时是以解释型语言方式运作，而输出为EXE程序是是以编译型语言方式运作。
可以看作是Visual Basic在.Net Framework平台上的升级版本，增强了对面向对象的支持。大多的VB.Net程序员使用Visual Studio .Net作为IDE（integrated development environment).SharpDevelop是另一种可用的开源的IDE。
