vb.net中的DataGrid控件显示不了数据了

Question

vb.net中的DataGrid控件显示不了数据了，运行报错是“未处理OleDbException 找不到可安装的ISAM”
报错的位置是objconn.Open()(打开数据库连接)
求高人指教一下！

Answer 1

public class Wb5
{
public static void main(String[] ags)
{
int[] a = new int[5];
int i,j;
System.out.println("请输入一个5位正整数,从万位开始输~");
for(i = 4; i >=0; i --)
{
a[i] = Integer.parseInt(javax.swing.JOptionPane.showInputDialog(null, "Input value here"));

}
for(j=0;j<=a.length-1;j++)
{
if(a[j] % 2 == 0)
{
System.out.println(a[j]+" is Even~~");
}
else
{
System.out.println(a[j]+" is Odd~~");
}
}

}
}

Answer 2

跟datagrid没关
是数据库连接的问题
检查一下你的connection string吧~

Answer 3

Imports Microsoft.VisualBasic
Imports System.Data
Imports System.Data.SqlClient

dim conn As New SqlConnection
Dim ds As New DataSet
Dim objAdaper As New SqlDataAdapter
conn.ConnectionString ="server=a;database=b;uid=c;pwd=d;"
conn.Open()
objAdaper = New SqlDataAdapter("select * from table1", conn)
objAdaper.Fill(ds)

GridView.DataSource = ds
GridView.DataBind()
