vb+access 打开文件
代码如下:'If ListView1.SelectedItem.Text <> " " Then
'Dim FileName As String
'Dim a As Long
'conn.Open "Provider=Microsoft.Jet.OLEDB.4.0;Persist Security Info=False;Data Source=db1.mdb;Jet OLEDB:Database Password=1234"
'Rs.Open "select * from file1", conn, adOpenKeyset, adLockPessimistic '打开数据库的表
'FileName = ListView1.SelectedItem.Text
'If FileName = "" Then
'Exit Sub
'End If
'End If
'Call ShellExecute(hwnd, "Open", App.Path & "\" & ListView1.SelectedItem.Text, "", App.Path, 1)
希望实现的功能:文件在数据库中用超级链接的方式存储,在listview里能够打开文件 --------------------编程问答-------------------- ListView1.SelectedItem.Text 显示的是什么文字? --------------------编程问答-------------------- 顶先. --------------------编程问答-------------------- 文件格式是什么呢?excel,word...., --------------------编程问答-------------------- 给你几个函数,绝对能用

End Sub --------------------编程问答-------------------- 很简单阿,你设一个字符串类型的字段,然后把要打开的文件名连同路径保存在这个字段中
读的时候用SHELL运行这个字符串,系统就会自动打开它了 --------------------编程问答-------------------- Shell "start.exe http://www.baidu.com/", vbHide '这个可以打开连接
示例
FileName = ListView1.SelectedItem.Text
Shell "start.exe " & FileName, vbHide
补充:VB , 数据库(包含打印,安装,报表)
