createfile极不稳定？(100分)

一模一样的程序。<br>其中用到createfile。<br>在我机器上，百分百打开成功，再其他人的机器上却<br>失败率极高（返回句柄为65535）<br>不知道各位有无遇到这种情况？<br><br>var hRead,hWrite &nbsp;: Word ;<br><br>&nbsp;hWrite := CreateFile(sWritePath,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;GENERIC_WRITE Or GENERIC_READ,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;FILE_SHARE_WRITE or FILE_SHARE_READ,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;nil,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;OPEN_EXISTING,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0);<br><br>&nbsp;hRead := CreateFile(sReadPath,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;GENERIC_WRITE Or GENERIC_READ,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;FILE_SHARE_WRITE or FILE_SHARE_READ,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;nil,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;OPEN_EXISTING,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0,<br>&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp;0);

nt还是9x?

都不稳定。嘻嘻。<br>

别人机器上没有你要打开的文件。

首先可以确定，存在这个文件（其实是设备），<br>但只是打开成功的几率比较低．（不稳定）

hWrite, hRead: WORD ? 应该是 DWORD (或 THandle)吧。敲错了？

用 f: File;<br>Assigned(F,'c:/1.txt');<br>Rewrite(F);<br>write(F,'');<br>closeFile(f);<br>这样的方式呢？ 虽然傻点，也许会更好的。<br>

word/dword有影响么？

CreateFile 返回的是 DWORD,如果你的 hWrite, hRead 是 WORD 的话,返回的双字的高字<br>就被截掉了,有可能返回了大于 65535 的值,但又不是 invalid_handle,而你只能得到<br>65535.

原来如此！多谢各位！！
