vb。net制作mdb vbnet mybase
怎样用VB.NET 做学生管理系统
1:Access,建立数据库,数据库命名为Database1.mdb。

(注意:这里的后缀是MDB,如果Access是2007版本的,保存的时候要另存为2003版本的才行,因为,VB不直接支持07版的accdb后缀格式!)
2:数据库建立后就进入了数据表界面,可以输入数据了,输完以后CRRL+S保存,输入表名,这里表名为test,ok,准备工作搞定。
菜单中找到工程→部件→勾选 ,
Microsoft ADO Data Control 6.0
Microsoft Hierarchical Flexgrid Control 6.0
勾选后左侧工具栏里就多了两个控件即 ADODC控件和MSHFlexGrid控件。
选择 ADODC控件和MSHFlexGrid控件,放在窗体的合适位置
设置ADODC控件的属性:
右键窗体内ADODC1控件
1:ADODC属性页→通用→选择使用连接字符串→点击生成→选择Microsoft Jet 4.0 OLE DB Provider 点击下一步→选择之前准备好的数据库→点击测试连接,显示测试成功则ok,确定。
2:ADODC属性页→记录源→命令类型选择2-adcmdtable,表或存储过程名称选择之前建立的数据表test,点击确定,ADODC属性设置完成。
设置MSHFlexGrid控件的属性:
VB右侧属性表里,找到datasource,选择adodc1
就完事了

VB.NET如何生成ACCESS数据库?并生成表。 VB.NET
我的需求就是先填写好表和表中字段的名称,然后点击一个按钮,就在指定的路径生成一个ACCESS数据库。而不是事先手动创建。 请知道的各位附上完整代码,本人刚接触VB.NET,有些东西还不是很了解。谢谢。
vb.net 写入mdb数据库
1、首先,你得做一个oledbconnection对象,这个对象有个连接字符串的属性,你需要设置
2、做一个oledbcommand对象,这个对象有个操作字符串(SQL语句)需要设置
3、打开oledbconnection对象
4、执行oledbcommand对象
5、关闭oledbconnection对象
程序结束,希望对你有帮助
