在局域网中的某台电脑（最好选择性能较好的机子）上建立一个共享文件夹（要把权限设置为所有人都可读可写），然后把文件复制到这个文件夹，只要同一局域网的其他电脑都能够在桌面的“网络”（XP之前的系统是叫“网上邻居”）中看到这个文件，并且能够进行读取、修改、删除等操作，那么在VB软件中也同样能够做到这些操作，比如打开文件可以这样：
Open
"\\电脑名称或IP地址\共享文件夹名\要操作的文件名.扩展名"
For
Input
As
#1
从中我们可以看到，操作网络共享文件与操作本地文件几乎是没有什么区别的，事实上如果把共享文件夹映射到本地服务器的虚拟驱动器上，比如把
"\\电脑名称或IP地址\共享文件夹名"
映射为驱动器z，那么上述语句就变为：
Open
"z:\要操作的文件名.扩展名"
For
Input
As
#1
这样就跟操作本地文件完全一样了！
PS：请尽量把局域网内的电脑都设为同一个家庭组或工作组，这样可以省去许多连接上的麻烦
网络共享文件夹不能直接用VB里的Open语句，那是为本地文件用的
网络文件夹用API函数OpenFile
具体用法：
FileHandle = OpenFile( "\\ " IP地址 文件路径 "\ " 文件名, lpReOpenBuff, OF_READ)
我不会VB，但是都是.net。c#的代码稍微转换一下就可以了。
C#实现访问网络共享文件夹，使用 WNetAddConnection2A 和 WNetCancelConnection2A。
在目标服务器建立共享文件夹，建立访问账号test;

//int status = NetworkConnection.Connect(@"\\192.168.0.2\test", localpath, @"test", "test");
int status = NetworkConnection.Connect("\\\\192.168.0.2\\test", localpath, @"test", "test");
if (status == (int)ERROR_ID.ERROR_SUCCESS)
{
FileStream fs = new FileStream(localpath + @"\\123.txt", FileMode.OpenOrCreate);
using (StreamWriter stream = new StreamWriter(fs))
{
stream.WriteLine("你好呀，成功了");
stream.Flush();
stream.Close();
}
fs.Close();
}
else
{
Console.WriteLine(status);
}
NetworkConnection.Disconnect(localpath);
}
VB访问网络共享文件夹与访问本地文件夹是没有什么区别的，比如你要打开与你的电脑同一个局域网的另一台名为“abcd”的电脑的共享文件夹“xxx”中的文本文件“123.txt”，可以这样：
Open "\\abcd\xxx\123.txt" For Input As #1
也可以用IP地址，比如：
Open "\\192.168.1.103\xxx\123.txt" For Input As #1
