using WIN32 API "CopyFile"

[kleinsun]

Dear all,

I am trying to use WIN32 API "CopyFile" to copy a file from a remote machine to local.

bRet = CopyFile(src, dest, false);

"dest" is defined as

dest = "\\\\desk\\data\\1.txt";

But this operation always fails. Could anybody give me a little hint? Thanks!

Do you have write permissions on that computer and directory? Try to copy manually and see if it works.

I can read / write that folder. Just wonder why API fails?

This worked for me, where VICTOR is another computer on my LAN.

#include <iostream>
#include <string>
#include <windows.h>
using namespace std;
int main()
{
    string src = "C:\\Users\\Ancient_Dragon\\Documents\\test.txt";
    string dest = "\\\\VICTOR\\SharedDocs\\test.txt";

    BOOL rval = CopyFile(src.c_str(), dest.c_str(), FALSE);
    cout << rval << "\n";
}

GetLastError() gives you an error code (defined in winerror.h), which might prove to be useful.

Do not know why it did not work for me.

GetLastError() returns 3. What does 3 mean?

BTW, if I map the shared folder as a network drive like \\desk\data -> X:\, the following code will work.

dest = "Y:\\1.txt";
bRet = CopyFile(src, dest, false);

    string dest = "\\\\VICTOR\\SharedDocs\\test.txt";

    cout << rval << "\n";

GetLastError()'s error codes are defined in <winerror.h>, you can always lookup them there. 3 means ...

//  The system cannot find the path specified.
//
#define ERROR_PATH_NOT_FOUND             3L

So, for some reason (unknown to me, sorry), apparently the network path is not found.
