即使文件存在于网络驱动器中，也不会成功

问题描述

我有一个应用程序，它从我的系统中映射的网络驱动器中读取文件。



此文件在一台机器中创建（比如Machine-A ）到其本地驱动器并尝试使用fopen（）从另一台机器（比如Machine-B）打开。但即使Machine-A创建的文件，Machine-B也无法使用fopen（）访问该文件。



当我在循环中尝试fopen（）时，然后发现有些时间仅在3-4秒后fopen成功。但是我可以在fopen获得成功之前在Windows资源管理器中看到创建的文件。



注意：此问题仅在Windows7计算机中发生。这两台机器都是windows7。





请提出解决方案，如果有人已经遇到过这个问题。



请参阅我用于阅读文件的代码。

 for（int nIndx = 0; nIndx< 100000; nIndx ++）
 {
 fp = fopen（Z：\\TEST \\SAMPLE.000，r）; //从网络驱动器打开。 
 if（NULL！= fp）
 {
 OutputDebugString（_T（File Found !!!））; 
 fclose（fp）; 
 AfxMessageBox（_T（File Found !!!））; 
休息; 
} 
 else 
 {
 OutputDebugString（_T（File not found ...））; 
} 
} 
 

解决方案

I have an application which reads the file from a network drive which is mapped in my system.

This file is created in one machine (say Machine-A) to the its local drive and trying to open from another machine(say Machine-B) using fopen(). But even though the file created by Machine-A, Machine-B cannot access the file using fopen().

When I tried the fopen() inside a loop, then it is found that some timed only after 3-4 seconds fopen is success. But I can see the created file in windows explorer before the fopen gets success.

Note: This issue is happening only in Windows7 machine. Here both machines are windows7.


Please suggest solution, if anyone already faced this problem.

Please see the code which I used for reading the file.

for( int nIndx = 0; nIndx < 100000; nIndx ++ )
{
    fp = fopen( "Z:\\TEST\\SAMPLE.000", "r" ); // open from Network drive.
    if( NULL != fp )
    {
        OutputDebugString( _T( "File Found !!!" ));
        fclose( fp );
        AfxMessageBox( _T( "File Found !!!" ));
        break;
    }
    else
    {
        OutputDebugString( _T( "File not found ..." ));
    }
 }
