在VB中动态创建数据库
新建工程.添加控件对应写上代码

以下为引用的内容：
Private Sub Command2_Click()
    Dim myDB As DAO.Database
    'Set myDB = DAO.OpenDatabase("d:\mydb3.mdb")
    Set myDB = DAO.OpenDatabase(App.Path + "/mydb.mdb")
    Dim d As String
    d = "delete * from NewTable1"
     myDB.Execute d
     MsgBox "成功删除全部记录"
End Sub

Private Sub Command3_Click()
    Dim myDB As DAO.Database
    'Set myDB = DAO.OpenDatabase("d:\mydb3.mdb")
    Set myDB = DAO.OpenDatabase(App.Path + "/mydb.mdb")
    Dim e As String
    e = "drop TABLE NewTable1"
    myDB.Execute e
End Sub

Private Sub Form_Load()
    Dim myDB As DAO.Database
    'Set myDB = DAO.Workspaces(0).CreateDatabase("d:\mydb3.mdb", dbLangGeneral)
     Set myDB = DAO.Workspaces(0).CreateDatabase(App.Path + "/mydb.mdb", dbLangGeneral)
    Dim str_SQL As String
    str_SQL = "Create Table NewTable1(Field1 Text(10),Field2 Short)"
    myDB.Execute str_SQL
    Dim a As String
    a = "Insert INTO NewTable1 VALUES ('litao','21')"
    myDB.Execute a

    str_SQL = "Create Table NewTable2(Field1 Text(10),Field2 Short)"
    myDB.Execute str_SQL
    myDB.Close
    MsgBox "成功创建mydb3.mdb数据库外加一条记录litao 21"
    End Sub

Private Sub Command1_Click()
    Dim myDB As DAO.Database
    'Set myDB = DAO.OpenDatabase("d:\mydb3.mdb")
    Set myDB = DAO.OpenDatabase(App.Path + "/mydb.mdb")
    Dim c As String
    c = "Insert INTO NewTable1 VALUES ('liqiao','20')"
    myDB.Execute c
MsgBox "成功插入一条记录liqiao 20"
End Sub
