Hallo to all my senior, I don't know why it is no any error showing and can't save it in Access Database.大家好,我不知道为什么没有显示任何错误并且无法将其保存在 Access 数据库中。
The whole code is in the button, I explain how I want my the program works:整个代码在按钮中,我解释了我希望我的程序如何工作:
1.) I have a unbound datagridview that can add data from few textbox. 1.) 我有一个未绑定的 datagridview,可以从几个文本框中添加数据。 2.) A button called Check - Out, this button is for passing my datagridview data to Access Database.....this is the problem I face.....Can somebody help me to solve it..... 2.) 一个名为Check - Out 的按钮,这个按钮用于将我的datagridview 数据传递到Access 数据库.....这是我面临的问题.....谁能帮我解决它.....
Thx a lot...多谢...
I also referred to the this link, but I'm not too familiar with C# Insert all data of a datagridview to database at once我也提到了这个链接,但我对 C# 不太熟悉将 datagridview 的所有数据一次性插入数据库
You're making things more complex than they need to be.你让事情变得比他们需要的更复杂。 Just create a DataTable
and bind it to the grid.只需创建一个DataTable
并将其绑定到网格。 When it comes time to save the data, it takes one call to the Update
method of a data adapter to save the lot.当需要保存数据时,只需调用一次数据适配器的Update
方法即可保存大量数据。 You use the same data adapter to generate the schema in the DataTable
by calling FillSchema
and then use a command builder to generate the INSERT
command or you can build the schema and the INSERT
command manually.您可以使用相同的数据适配器通过调用FillSchema
在DataTable
生成架构,然后使用命令生成器生成INSERT
命令,或者您可以手动生成架构和INSERT
命令。 Here are some examples:这里有些例子:

you were required to open connection before the for loop and remove the comment at Command.ExecuteNonQuery()您需要在 for 循环之前打开连接并删除 Command.ExecuteNonQuery() 处的注释
your code will be as shown below您的代码将如下所示
Dim Con As OleDbConnection = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=Music_Sales_Database.mdb;")
Dim Com As OleDbCommand
Dim SaleCode As Integer
Dim MusicID As String
Dim SubTotalPrice As Decimal
Dim Copies1 As Integer
Dim STR1 As String
SaleCode = 1
Com = New OleDbCommand
Com.Connection = Con
Connection.open()
For x As Integer = 0 To SalesDataGridView.Rows.Count - 1
MusicID = SalesDataGridView.Rows(x).Cells(0).Value
SubTotalPrice = SalesDataGridView.Rows(x).Cells(5).Value
Copies1 = SalesDataGridView.Rows(x).Cells(3).Value
STR1 = "INSERT INTO Sales(Sales_ID, Sales_Date, Copies, Music_ID, Staff_ID, Total_Price) VALUES (@Sales_ID, @Sales_Date, @Copies, @Music_ID, @Staff_ID, @Total_Price)"
Dim Comm As New OleDbCommand(STR1, Con)
Comm.Parameters.AddWithValue("@Sales_ID", SaleCode)
Comm.Parameters.AddWithValue("@Sales_Date", txtDateAndTime)
Comm.Parameters.AddWithValue("@Copies", Copies1)
Comm.Parameters.AddWithValue("@Music_ID", MusicID)
Comm.Parameters.AddWithValue("@Staff_ID", txtStaff_ID)
