有什么错

[zsms2]

Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
myRow.Item(0) = txtBookID.Text
myRow.Item(1) = txtBookName.Text
myRow.Item(2) = txtbookstate.Text
End Sub

Private Sub btnSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEdit.Click
Try
ADOcmd.Update(ds, "tblbooks")
Catch
MessageBox.Show(Err.Description, "保存失败", MessageBoxButtons.OK, MessageBoxIcon.Error)
End Try
End Sub
程序中还要执行UpdateCommand命令吗？

[zsms2]

但是当我执行程序的时候总在那里跳出异常，说我没有执行UpdateCommand！

看不懂什么意思，按我自己的体会，Adapater.updata之前，最好重新设置其selectcommand
例如: DA = new Adapater(SqlSelectString,Connectionstring)查询表
则更新该写成:
DA.selectcommand.commandtext = SqlSelectString
DC = new CommandBuild(DA)
DA.Update(DataSet1,"TableName")

不需要了.
