如何将Access和Excel导入到Mysql中之三
二。导库的VB程序
这个工程要使用一些对象库,在数据库访问方面,决定使用ADO(ActiveX Data Objects),对于使用过ASP的人,这个名字应该非常熟悉了,实际上,它在VB中的应用也是几乎一样的,由于要操作Excel,还要引用一个扩展的对象库。点菜单中的“工程”---“引用”,选择“Microsoft ActiveX Data Objects 2.6 Library”和“Microsoft Excel 9.0 Object Library”,在引用列表中,可引用对象库的版本或许有所不同,选择类似的最新版本就可以了。要使用对话框和进度条,还要引用一些部件,点菜单中的“工程”--“部件”,选择“Microsoft Common Dialog Control 6.0(SP3)”和“Microsoft Windows Common Controls 6.0(SP3)”。
界面如图一所示
图中各数字表示的控件分别是:
1-3:3个均为TextBox控件,名字分别为mdbfilename,mdbpassword,xlsfilename,mdbfilename用来指示导入Access文件的路径和文件名,mdbpassword用来输入Access文件的密码,xlsfilename用来指示导入Excel文件的路径和文件名;
4:名称为select_mdbfile,CommandButton控件,用来选择要导入的Access文件;
5:名称为importMDB,CommandButton控件,选择好文件后,用该按钮导入MDB文件
6:名称为CommonDialog1,CommonDialog控件
7:名称为select_xlsfile,CommandButton控件,用来选择要导入的Excel文件;
8:名称为importXLS,CommandButton控件,选择好文件后,用该按钮导入XLS文件;
9:名称为CommonDialog2,CommonDialog控件
10:名称为prgBar1,进度条(ProgressBar),当要导入很多记录时,使用进度条可以指示当前的导入进度
11:名称为StatusBar1,状态条(StatusBar),指示导入的进展状态,包括“正在导入”,“导入完成”等。
要将Style设置为“1-sbrSimple”
在程序的头部作以下声明
Option Explicit
Dim Cn As New ADODB.Connection
Dim Cnmysql As New ADODB.Connection
Dim Rs As New ADODB.Recordset
Dim Rsmysql As New ADODB.Recordset
Function replace_str(srcstr As String)
srcstr = Replace(srcstr, "", "")
replace_str = Replace(srcstr, "'", "'")
End Function
双击form,在装载form时输入以下的代码
Private Sub Form_Load()
'将进度条设置为不可见
prgBar1.Visible = False
'连接mysql数据库,pwd为数据库的密码,uid为用户名,dsn为数据源的名称
Cnmysql.ConnectionString = "uid=root;pwd=;dsn=build"
Cnmysql.Open
End Sub
