手里银行卡较多，经常忘记还信用卡，想做个应用自动查询银行卡余额。
在做网页自动登录时，碰到银行安全控件，控件屏蔽了windows的sendmessage和postmessage
只能求助winio，模拟最底层的按键
1. 下载winio
http://www.internals.com/utilities/WinIo.zip
2.安装数据签名证书
3. 打开windows的测试模式
管理员模式在 cmd 下运行 bcdedit /set testsigning on
4. 代码
导入方法
[DllImport("WinIo32.dll")] public static extern bool InitializeWinIo(); [DllImport("WinIo32.dll")] public static extern bool GetPortVal(IntPtr wPortAddr, out int pdwPortVal, byte bSize); [DllImport("WinIo32.dll")] public static extern bool SetPortVal(uint wPortAddr, IntPtr dwPortVal, byte bSize); [DllImport("WinIo32.dll")] public static extern byte MapPhysToLin(byte pbPhysAddr, uint dwPhysSize, IntPtr PhysicalMemoryHandle); [DllImport("WinIo32.dll")] public static extern bool UnmapPhysicalMemory(IntPtr PhysicalMemoryHandle, byte pbLinAddr); [DllImport("WinIo32.dll")] public static extern bool GetPhysLong(IntPtr pbPhysAddr, byte pdwPhysVal); [DllImport("WinIo32.dll")] public static extern bool SetPhysLong(IntPtr pbPhysAddr, byte dwPhysVal); [DllImport("WinIo32.dll")] public static extern void ShutdownWinIo(); [DllImport("user32.dll")] public static extern int MapVirtualKey(uint Ucode, uint uMapType);
初始化
private WinIO() { IsInitialize = true; } public static void Initialize() { if (InitializeWinIo()) { KBCWait4IBE(); IsInitialize = true; } else throw new Exception("Load WinIO Failed!"); } public static void Shutdown() { if (IsInitialize) ShutdownWinIo(); IsInitialize = false; }
模拟键盘按下和弹起
//等待键盘缓冲区为空 private static void KBCWait4IBE() { int dwVal = 0; do { bool flag = GetPortVal((IntPtr)0x64, out dwVal, 1); } while ((dwVal & 0x2) > 0); } // 模拟键盘标按下 public static void KeyDown(Keys vKeyCoad) { if (!IsInitialize) return; int btScancode = 0; btScancode = MapVirtualKey((uint)vKeyCoad, 0); //按键转换成扫描码 KBCWait4IBE(); SetPortVal(0x64, (IntPtr)0xD2, 1); //发送准备写命令 KBCWait4IBE(); SetPortVal(0x60, (IntPtr)btScancode, 1); //写入按键 } // 模拟键盘弹出 public static void KeyUp(Keys vKeyCoad) { if (!IsInitialize) return; int btScancode = 0; btScancode = MapVirtualKey((uint)vKeyCoad, 0); KBCWait4IBE(); SetPortVal(0x64, (IntPtr)0xD2, 1); KBCWait4IBE(); SetPortVal(0x60, (IntPtr)(btScancode | 0x80), 1); //弹出 }
