Tips & Tricks:

Parameters

• servername: String that specifies the DNS or NetBIOS name of the remote server on which the function is to execute. If this parameter is NULL, the local computer is used.

• device: String that specifies the name of the device to check for shared access. Drive letter must be upper case.

• type: Specify the type of the shared device. This parameter is set only if the function returns successfully.

C# Sample Code:

    String server = "myServer"; // could be empty for local computer
    String localPath = @"C:\shared folder";
    SHARE_TYPE shareType;

    Boolean exists;

    NetError result = (NetError)NetShareCheck(server, localPath, out shareType);

    switch (result)
    {
        case NetError.NERR_Success: exists = true;
        break;
        case NetError.ERROR_NOT_ENOUGH_MEMORY: throw new OutOfMemoryException();

        case NetError.DeviceNotShared: exists = false;
        break;
    }
