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 ..." ));
    }
 }
