利用VB远线程注入技术实现键盘拦截的例子(无DLL)
从网上搜集到的VB代码，用EXE方式实现了远程注入，不过在反病毒软件的保护下，有可能导致注入失败。转贴这个代码，仅供大家学习和参考。
一、窗口代码：
Option Explicit
Private Sub cmdLock_Click()
If LockKeyboard(True) Then
cmdLock.Enabled = False
cmdUnLock.Enabled = True
End If
End Sub
Private Sub cmdUnLock_Click()
If LockKeyboard(False) Then
cmdLock.Enabled = True
cmdUnLock.Enabled = False
End If
End Sub
Private Sub Form_Load()
Dim bIsLock As Boolean
bIsLock = GetKeyboardState
cmdLock.Enabled = Not bIsLock
cmdUnLock.Enabled = bIsLock
End Sub
Option Explicit
Private Sub cmdLock_Click()
If LockKeyboard(True) Then
cmdLock.Enabled = False
cmdUnLock.Enabled = True
End If
End Sub
Private Sub cmdUnLock_Click()
If LockKeyboard(False) Then
cmdLock.Enabled = True
cmdUnLock.Enabled = False
End If
End Sub
Private Sub Form_Load()
Dim bIsLock As Boolean
bIsLock = GetKeyboardState
cmdLock.Enabled = Not bIsLock
cmdUnLock.Enabled = bIsLock
End Sub
二、模块代码：
Option Explicit
'是否包含处理其它键盘消息，True表示处理.
#Const INC_OTHER_KEY = True
'注意，以下所有双版本的API均声明成了 UNICODE 版。 并且许多地方与VB的API浏览器生成的代码有所不同。

虽然在VB里实现XP风格很简单，但是要使用XP风格同时又让按钮显示图片，则实现起来要麻烦一些，为此，我写了一个控件来实现前述功能，同时让读者可以从中了解XP主题界面的绘制过程。
使用办法很简单，在VB里新建一个工程，然后添加一个控件模块，粘贴以下代码，再将控件放置到窗口即 ......
前阵子写了一个目录名/文件名的获取小程序，这两天居然又被名称批量修改麻烦了一下，所以再写一个吧。
注意：你要是只想写一次的话，用批处理更方便。只有多次使用的情况下，自己写程序才有意义。
VB中进行名称修改很容易,用到的就是Name这个函数，用法如下：
Name OldName As NewName，它不仅可以改写名称，而且可以更� ......
