【ce问题求问】从wince拷贝文件到pc的问题
String RemoteFileName2 = @ "\Application\stwms\receive.txt "; // 远程设备文件名2
private const uint GENERIC_READ = 0x80000000;
private const short FILE_ATTRIBUTE_NORMAL = 0x80; // 设置文件属性
String LocalFileName = @ "c:\test.txt "; // 本地计算机文件名FileStream localFile;
int bytesread = 0;
remoteFile2 = CeCreateFile(RemoteFileName2, GENERIC_READ, 0, 0, 1, FILE_ATTRIBUTE_NORMAL, 0);
long iresult = CeReadFile(remoteFile, readbuffer, 4096, ref bytesread, 0);
// 检查文件是否读取成功
if ((int)remoteFile2 == INVALID_HANDLE_VALUE)
{
throw new Exception( "Could not read remote file ");
}
localFile = new FileStream(LocalFileName, FileMode.Open);
// 读取4K字节
localFile.Write(readbuffer, 0, readbuffer.Length);
localFile.WriteByte(readbuffer);
localFile.Close();
// 关闭远程文件
CeCloseHandle(remoteFile);
[DllImport( "rapi.dll ", CharSet = CharSet.Unicode, SetLastError = true)]
internal static extern IntPtr CeCreateFile(string lpFileName, uint dwDesiredAccess, int dwShareMode, int lpSecurityAttributes, int dwCreationDisposition, int dwFlagsAndAttributes, int hTemplateFile);
[DllImport( "rapi.dll ", CharSet = CharSet.Unicode)]
internal static extern int CeReadFile(IntPtr hFile, byte[] lpBuffer, int nNumberOfBytesToRead, ref int lpNumberOfBytesRead, int lpOverlapped);
-------------------------------
就是想把ce中的一个文件拷贝到pc里,现在的问题是remoteFile2始终为-1,总是抛出“Could not read remote file”的异常,大家帮忙看看哪儿错了,或者谁能给个例子,刚学ce的编程,很多不清楚
------解决方案--------------------不会,关注一下
------解决方案--------------------这个要关注下,楼住解决要说下.顶
------解决方案--------------------是否没有权限
