隐藏“开始”栏
HWND lpClassName;
lpClassName = ::FindWindow(TEXT("HHTaskBar"), NULL);
::ShowWindow(lpClassName, SW_HIDE);
只隐藏Taskbar还不行，你得把work area 设为整个屏幕：
int screenx=GetSystemMetrics(SM_CXSCREEN);
int screeny=GetSystemMetrics(SM_CYSCREEN);
CRect rcWorkArea;
rcWorkArea.left = 0;
rcWorkArea.right = screenx;
rcWorkArea.top = 0;
rcWorkArea.bottom = screeny;
::SystemParametersInfo( SPI_SETWORKAREA, 0, &rcWorkArea, SPIF_SENDCHANGE );
如何获取 Pocket PC 2002 装置的序列号(以下例程获取的装置的序列号通常是Flash ROM的ID号.)?
--------------------------------------------------------------------------------
从 Pocket PC 2000 开始, 微软就建议OEM厂商提供一个叫 KernelIoControl 的函数, 以便用户能访问Pocket PC 2002装置内建的序列号; 遗憾的是, 几乎没有厂商提供这个支持.
从 Pocket PC 2002 开始, 微软开始强制OEM厂商提供此函数. 目前市面上所有经过biplip测试的Pocket PC 2002装置都支持这个函数调用.
以下是个调用例子:
#include
extern "C" __declspec(dllimport)
BOOL KernelIoControl(
DWORD dwIoControlCode, LPVOID lpInBuf, DWORD nInBufSize,
LPVOID lpOutBuf, DWORD nOutBufSize, LPDWORD lpBytesReturned
);
#define IOCTL_HAL_GET_DEVICEID CTL_CODE(FILE_DEVICE_HAL, 21, METHOD_BUFFERED, FILE_ANY_ACCESS)
CString GetSerialNumberFromKernelIoControl()
{
DWORD dwOutBytes;
const int nBuffSize = 256;
byte arrOutBuff[nBuffSize];
BOOL bRes = ::KernelIoControl(IOCTL_HAL_GET_DEVICEID,
0, 0, arrOutBuff, nBuffSize, &dwOutBytes);
if (bRes) {
CString strDeviceInfo;
for (unsigned int i = 0; i CString strNextChar;
strNextChar.Format(TEXT("%02X"), arrOutBuff);
strDeviceInfo += strNextChar;
}
CString strDeviceId =
strDeviceInfo.Mid(40,2) +
strDeviceInfo.Mid(45,9) +
strDeviceInfo.Mid(70,6);
return strDeviceId;
} else {
return _T("");
}
}

我用以下代码成功禁止任务栏被点击，但不知怎样才能解除，特此请教，谢谢。
LONG lOldWindowStyle;
RECT rectOldTaskBarRect;
HWND hOldhTaskBar = ::FindWindow(_T("HHTaskBar"),NULL);
while( hOldhTaskBar == NULL )
{
hOldhTaskBar = ::FindWindow(_T("HHTaskBar"),NULL);
Sleep( 1000 );
}
::GetWindowRect( hOldhTaskBar, &rectOldTaskBarRect );
::SetWindowPos( hOldhTaskBar, HWND_BOTTOM, 0, 0, 0, 0, SWP_HIDEWINDOW|SWP_NOACTIVATE|SWP_NOMOVE|SWP_NOSIZE);
lOldWindowStyle = GetWindowLong(hOldhTaskBar, GWL_STYLE);
::SetWindowLong( hOldhTaskBar, GWL_STYLE, lOldWindowStyle|WS_DISABLED );
比如控制打开一个jpg文件。
我用的是ShellExecute，好像有点问题：
ExecuteFile(LPCTSTR filename)
{
SHELLEXECUTEINFO info;
info.cbSize=sizeof(SHELLEXECUTEINFO);
info.fMask=SEE_MASK_NOCLOSEPROCESS;
info.hwnd=this->GetSafeHwnd();
info.lpVerb=L"open";
info.lpFile=filename;
info.lpParameters=NULL;
info.lpDirectory=NULL;
info.nShow=SW_SHOW;
return ShellExecuteEx(&info);
}
这会用IE来打开jpg
每次总是第一次的时候对，以后调用的时候总是自动调原来的东西，没有更新。还有其他更好用的api吗？
