在2000下使用TSHFileOpStruct 时，有时行有时不行，为什么？(50分)

For example, the file name "New Document.temp" will be truncated to "NewDocum.tem". <br><br><br><br>CAUSE<br>The default behavior of SHFileOperation causes this problem. This behavior only occurs when you use a relative path for the destination. <br><br><br><br>RESOLUTION<br>Use a full path instead of a relative path for the destination. <br><br><br><br>STATUS<br>This behavior is by design. <br><br>Additional query words: <br><br>Keywords : kbLib kbOSWinNT400 kbOSWin2000 kbSDKWin32 kbOSWin95 kbGrpShell <br>Issue type : kbprb <br>Technology : kbOSWinNT kbOSWinSearch <br><br><br>Last Reviewed: October 21, 2000<br>&amp;copy; 2001 Microsoft Corporation.

注意buf1,buf2必须至少比Str1,Str2的长度大2，因为他们必须用2个0结束字符串<br><br>StrPCopy(buf1,Str1);<br>buf1[Str1.Length()+1]=0;<br>StrPCopy(buf2,Str2);<br>buf2[Str2.Length()+1]=0;<br>

接受答案了.
