Hi everyone I'm new to here, I have problem to update my database record in VB ASP.NET webform. My code below will return dialog box that says record updated successfully when cmd.ExecuteNonQuery() > 0 but the record in database not being updated in fact. Sorry for my bad english. Please help thanks in advance.
Protected Sub btnUpdate_Click(sender As Object, e As EventArgs) Handles btnUpdate.Click
Dim staffUsername As String = Session("StaffUsername").ToString()
Dim staffFNm As String = txtStaffFNm.Text
Dim staffLNm As String = txtStaffLNm.Text
Dim staffEmail As String = txtStaffCpnyEmail1.Text + txtStaffCpnyEmail2.Text
Dim staffBDay As String = txtBirthday.Text
Dim staffPhone As String = txtPhoneNo.Text
Using con As New SqlConnection(ConfigurationManager.ConnectionStrings("SupportSystemDB").ConnectionString)
con.Open()
Dim myCommand As New SqlCommand("UPDATE STAFF SET StaffFNm = #staffFNm, StaffLNm = #staffLNm, StaffEmail = #staffEmail, StaffBirthday = #staffBDay, StaffPhone = #staffPhone WHERE StaffUsernm = #staffUsernm", con)
myCommand.Parameters.AddWithValue("#staffFNm", staffFNm)
myCommand.Parameters.AddWithValue("#staffLNm", staffLNm)
myCommand.Parameters.AddWithValue("#staffEmail", staffEmail)
myCommand.Parameters.AddWithValue("#staffBDay", staffBDay)
myCommand.Parameters.AddWithValue("#staffPhone", staffPhone)
myCommand.Parameters.AddWithValue("#staffUsernm", staffUsername)
If myCommand.ExecuteNonQuery() > 0 Then
Response.Write("<script>alert('Your Account Info Has Been Successfully Updated.');</script>")
con.Close()
Else
Response.Write("<script>alert('Record Update Failed.');</script>")
End If
End Using

Morning,
Hi, I get stuck on how to parse a value as parameter from one page to another.
Here what I've already done
On Functional.aspx.vb, I parse value to Functional_Sub.aspx from URL
For Each row As DataRow In dt.Rows
html.Append("<a href='Functional_Sub.aspx?flag=" + row(0) + "'>IKUTI</a>")
Next
What I get is
'Functional_Sub.aspx?flag=FUNCP-000001' in URL
On Functional_Sub.aspx.vb I try to get parsed value with
Dim flag As String = Request.Params("flag")
Private Function GetData() As DataTable
Dim Connbackbone As String = ConfigurationManager.ConnectionStrings("BackboneConnectionString").ConnectionString
Using con As New SqlConnection(Connbackbone)
Using cmd As New SqlCommand("SELECT a.[IDFuncChild], b.[IDFuncParent], a.[nmSubKat] FROM [EL_MstFunctional_SubKat] a inner join [EL_MstFunctional_Kat] b on b.[IDFuncParent] = a.[IDFuncParent] where IDFuncParent = #IDFuncParent order by b.IDFuncParent, a.IDFuncChild")
cmd.Parameters.AddWithValue("#IDFuncParent", flag)
Using sda As New SqlDataAdapter()
cmd.Connection = con
sda.SelectCommand = cmd
Using dt As New DataTable()
sda.Fill(dt)
Return dt
End Using
End Using
End Using
End Using
End Function
But I get this result
Request is not available in this context
Please guide me. Thanks
It should be after the page is generated.
Dim flag As String
Private Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
flag = Request.Params("flag")
End Sub
This code is working a PC. I have filled grid view with the dataset, so I suppose I can read Excel.
However, the insert to sql part is not working when I copy the code to the server and I don't know why. It is not throwing any errors.
I removed the try catch lines but still, there are no errors.
I am adding new code block, I did a test and wrote a siple insert code like;
Protected Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
Dim mysql_connection As New SqlConnection
mysql_connection.ConnectionString = "Data Source=SRV01;Initial Catalog=TR_Development;Persist Security Info=True;User ID=sa"
Dim command As String = "insert into gez_test (test) values ('c')"
Dim mysqlcommand As New SqlCommand
mysqlcommand.CommandType = CommandType.Text
mysqlcommand.CommandText = command
mysqlcommand.Connection = mysql_connection
If mysql_connection.State = ConnectionState.Closed Then mysql_connection.Open()
mysqlcommand.ExecuteNonQuery()
If mysql_connection.State = ConnectionState.Open Then mysql_connection.Close()
End Sub
And at server it is not inserting. What can be the problem any idea?

ASPxGridView1.DataBind()
I have a SQL table that looks similar to this:
1 | a | stuff...
2 | a | stuff...
3 | b | stuff...
4 | a | stuff...
5 | b | stuff...
I only want to show:
3 | b | stuff...
5 | b | stuff...
So I use this code to load the DataGridView:
Private Sub GetData()
Dim objConn As New SqlConnection(sConnectionString)
objConn.Open()
' Create an instance of a DataAdapter.
Dim daInstTbl As _
New SqlDataAdapter("SELECT * FROM Table WHERE Column = 'b'", objConn)
' Create an instance of a DataSet, and retrieve data from the Authors table.
daInstTbl.FillSchema(dsNewInst, SchemaType.Source)
daInstTbl.Fill(dsNewInst)
' Create a new instance of a DataTable
MyDataTable = dsNewInst.Tables(0)
daInstTbl.Update(dsNewInst)
End Sub
Private Sub InitializeDataGridView()
Try
' Set up the DataGridView.
With Me.DataGridView1
' Set up the data source.
.DataSource = MyDataTable
End With
Catch ex As SqlException
MessageBox.Show(ex.ToString, _
"ERROR", MessageBoxButtons.OK, MessageBoxIcon.Exclamation)
System.Threading.Thread.CurrentThread.Abort()
End Try
End Sub
Everything works great and until I want to delete 3 and renumber 4 and 5 down one to become 3 and 4. I have loops handling everything and the database is receiving the correct data except my DataGridView only shows the updates when I restart the program.
Here's my delete code:
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDelete.Click
Dim objConn As New SqlConnection(sConnectionString)
objConn.Open()
Dim daInstDeleteTbl As New SqlDataAdapter("SELECT * FROM Table", objConn)
Dim dsDeleteInst As New DataSet
Dim MyDeleteTable As DataTable
' Create an instance of a DataSet, and retrieve data from the Authors table.
daInstDeleteTbl.FillSchema(dsDeleteInst, SchemaType.Source)
daInstDeleteTbl.Fill(dsDeleteInst)
' Create a new instance of a DataTable
MyDeleteTable = dsDeleteInst.Tables(0)
'Begin Delete Code
Dim DeleteID, DeleteIndex As Integer
Dim MadeChange As Boolean = False
Integer.TryParse(TextBox1.Text, DeleteID)
Dim dgvIndexCount As Integer = MyDeleteTable.Rows.Count - 1
If MyDeleteTable.Rows(dgvIndexCount).Item(0) > DeleteID Then
Dim counter As Integer = -1
For Each row As DataRow In MyDeleteTable.Rows
counter += 1
If row.Item("Column") = DeleteID Then
DeleteIndex = counter
End If
Next
MadeChange = True
End If
drCurrent = MyDeleteTable.Rows.Find(DeleteID)
drCurrent.Delete()
If MadeChange = True Then
Dim i As Integer = 0
For i = DeleteIndex + 1 To dgvIndexCount
MyDeleteTable.Rows(i).Item(0) = MyDeleteTable.Rows(i).Item(0) - 1
Next
End If
'Send Changes to SQL Server
Dim objCommandBuilder As New SqlCommandBuilder(daInstDeleteTbl)
daInstDeleteTbl.Update(dsDeleteInst)
Dim daInstTbl As _
New SqlDataAdapter("SELECT * FROM Table WHERE Column = 'b'", objConn)
Dim objCommandReBuilder As New SqlCommandBuilder(daInstTbl)
daInstTbl.Update(dsNewInst)
End Sub
I think I am doing a lot of extra work just to do this wrong. Any ideas? Thanks.
When you invoke SqlDataAdapter.Update() the adapter updates the values in the database by executing the respective INSERT, UPDATE, or DELETE (from MSDN). The SELECT command is not executed. So you need to do it like this:
Insert/Update/Delete:
daInstTbl.Update(dsNewInst)
Select:
daInstTbl.Fill(dsNewInst)
Commit:
dsNewInst.AcceptChanges()
Example
Private connection As SqlConnection
Private adapter As SqlDataAdapter
Private data As DataSet
Private builder As SqlCommandBuilder
Private grid As DataGridView
Private Sub InitData()
Me.SqlSelect(firstLoad:=True, fillLoadOption:=LoadOption.OverwriteChanges, acceptChanges:=True)
Me.grid.DataSource = Me.data
Me.grid.DataMember = "Table"
End Sub
Public Sub SaveData()
Me.SqlInsertUpdateAndDelete()
Me.SqlSelect(fillLoadOption:=LoadOption.OverwriteChanges, acceptChanges:=True)
End Sub
Public Sub RefreshData(preserveChanges As Boolean)
Me.SqlSelect(fillLoadOption:=If(preserveChanges, LoadOption.PreserveChanges, LoadOption.OverwriteChanges))
End Sub
Private Sub SqlSelect(Optional firstLoad As Boolean = False, Optional ByVal fillLoadOption As LoadOption = LoadOption.PreserveChanges, Optional acceptChanges As Boolean = False)
If (firstLoad) Then
Me.data = New DataSet()
Me.connection = New SqlConnection("con_str")
Me.adapter = New SqlDataAdapter("SELECT * FROM Table WHERE Column = 'b'", connection)
Me.builder = New SqlCommandBuilder(Me.adapter)
End If
Me.connection.Open()
If (firstLoad) Then
Me.adapter.FillSchema(Me.data, SchemaType.Source, "Table")
End If
Me.adapter.FillLoadOption = fillLoadOption
Me.adapter.Fill(Me.data, "Table")
If (acceptChanges) Then
Me.data.Tables("Table").AcceptChanges()
End If
Me.connection.Close()
End Sub
Private Sub SqlInsertUpdateAndDelete()
If (Me.connection.State <> ConnectionState.Open) Then
Me.connection.Open()
End If
Me.adapter.Update(Me.data, "Table")
Me.connection.Close()
End Sub
PS: (Untested code)
My solution was to change the way I was declaring variables. Before I had:
Dim daInstTbl As _
New SqlDataAdapter("SELECT * FROM Table WHERE Column = 'b'", objConn)
The affect was that recalling the subroutine ignored this line because the variable daInstTbl was already declared previously. The solution was:
' Delete old instance of a Data____ classes
da = Nothing
ds = Nothing
dt = Nothing
If GetAll = False Then
da = New SqlDataAdapter(sSelCmd, objConn)
Else
da = New SqlDataAdapter(sSelAllCmd, objConn)
End If
' Create an instance of a DataSet, and retrieve data from the Authors table.
ds = New DataSet
da.FillSchema(ds, SchemaType.Source)
da.Fill(ds)
This cleared the information and allowed me to assign a new value. My subroutines serve double duty by assigning two query strings and then using an optional boolean to determine which version to use.
Dim sSelCmd As String = "SELECT * FROM Table WHERE Coloumn= 'b'"
Dim sSelAllCmd As String = "SELECT * FROM Table"
Private Sub GetData(Optional ByVal GetAll As Boolean = False)
Dim objConn As New SqlConnection(sConnectionString)
objConn.Open()
And that leads into the code above! Thanks for the help. Some of your concepts got my thoughts turning in the right direction and motivated me to clean up my code into a much more readable form.
My code should update old records and at the same time if the a new record is found it should likewise insert it in the DB... I am using table adpater in doing this method.
Here is the code:
Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
Dim pta As New PHDSTableAdapters.productdatabaseTableAdapter
pta.Updateproduct(TextBox1.Text, ComboBox1.Text, TextBox2.Text, TextBox3.Text, TextBox4.Text, TextBox5.Text)
pta.Fill(myds.productdatabase)
Dim lta As New PHDSTableAdapters.lotnoTableAdapter
Dim lt = lta.GetDataBylotno(TextBox5.Text)
Dim l As phaccess.PHDS.lotnoRow = lt.Rows(0)
Dim i As Integer
For i = 0 To DGV.Rows.Count - 1
For Each l In myds.lotno
Dim lot As String = DGV.Rows(i).Cells(1).Value
Dim del As Date = DGV.Rows(i).Cells(2).Value
Dim exp As Date = DGV.Rows(i).Cells(3).Value
Dim quantity As Integer = DGV.Rows(i).Cells(4).Value
Dim sup = DGV.Rows(i).Cells(5).Value
Dim disc = DGV.Rows(i).Cells(6).Value
If l.productid = TextBox5.Text Then
Dim lotnumber As String = l.lotnumber
If l.lotnumber <> lot Then
'the error occurs in the insert statement as it would create duplicates 'of the index...the index of the table is the lot number
lta.Insert(TextBox5.Text, lot, del, exp, quantity, sup, disc)
Else
lta.Updateedit(del, exp, quantity, sup, disc, lot)
lta.Fill(myds.lotno)
End If
End If
If lot = "" Then
closeform()
lta.Fill(myds.lotno)
Button3.Enabled = False
Button1.Visible = True
Button3.Visible = False
Button1.Enabled = False
Exit Sub
End If
Next
Next
End Sub
If you need anything else to help me solve this please do ask.
thank you
you can use "DataTable" to upadate DataGridView in your table
For displaying data:
Dim sql As String = "SELECT * FROM table_name"
sCommand = New SqlCommand(sql, conn)
sAdapter = New SqlDataAdapter(sCommand)
sBuilder = New SqlCommandBuilder(sAdapter)
sDs = New DataSet()
sAdapter.Fill(sDs, "table_name")
sTable = sDs.Tables("table_name")
DataGridView1.DataSource = sTable
for updating:
sAdapter.Update(sTable)
i hope this helps
Why my set of codes didn't update in DataSet? Then it goes to Error. Please anyone check this code and point me out where I am missing. Thanks in advance!
Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
Dim conxMain As New SqlConnection("Data Source=SERVER;Initial Catalog=DBTest;Persist Security Info=True;User ID=username;Password=pwds")
Dim dadPurchaseInfo As New SqlDataAdapter
Dim dsPurchaseInfo As New DataSet1
Try
Dim dRow As DataRow
conxMain.Open()
Dim cmdSelectCommand As SqlCommand = New SqlCommand("SELECT * FROM Stock", conxMain)
cmdSelectCommand.CommandTimeout = 30
dadPurchaseInfo.SelectCommand = cmdSelectCommand
Dim builder As SqlCommandBuilder = New SqlCommandBuilder(dadPurchaseInfo)
dadPurchaseInfo.Fill(dsPurchaseInfo, "Stock")
For Each dRow In dsPurchaseInfo.Tables("Stock").Rows
If CInt(dRow.Item("StockID").ToString()) = 2 Then
dRow.Item("StockCode") = "Re-Fashion[G]"
End If
Next
dadPurchaseInfo.Update(dsPurchaseInfo, "Stock")
Catch ex As Exception
MsgBox("Error : ")
Finally
If dadPurchaseInfo IsNot Nothing Then
dadPurchaseInfo.Dispose()
End If
If dsPurchaseInfo IsNot Nothing Then
dsPurchaseInfo.Dispose()
End If
If conxMain IsNot Nothing Then
conxMain.Close()
conxMain.Dispose()
End If
End Try
End Sub
Does your condition in the loop get executed (set a break point!)? Where is the error thrown? What error?
Also, why does it use ToString at all? This seems redundant.
If CInt(dRow.Item("StockID")) = 2 Then
Should be enough.
Finally, you’re performing redundant cleanup:
If conxMain IsNot Nothing Then
conxMain.Close()
conxMain.Dispose()
End If
Dispose implies Close – no need to perform both operations:
Close and Dispose are functionally equivalent.
[Source: MSDN]
Does your dataAdapter has update command ?
(it looks like it doesn't - so it doesn't know what do to with update....)
Here is an Update Command example:(for an employee table with 3 columns - as listed below:
UPDATE [Employee]
SET [name] = #name
, [manager] = #manager
WHERE (([id] = #Original_id) AND
((#IsNull_name = 1 AND [name] IS NULL) OR
([name] = #Original_name)) AND
((#IsNull_manager = 1 AND [manager] IS NULL) OR
([manager] = #Original_manager)));
SELECT id
, name
, manager
FROM Employee
WHERE (id = #id)
You can see it is a general update that can handle changes in any field.
I got it from the error correction of my program by Konard Rudolph!
Private Sub btnUpdate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnUpdate.Click
Dim conxMain As New SqlConnection("Data Source=SERVER;Initial Catalog=DBTest;Persist Security Info=True;User ID=username;Password=pwds")
Dim dadPurchaseInfo As New SqlDataAdapter
Dim dsPurchaseInfo As New DataSet1
Try
Dim dRow As DataRow
conxMain.Open()
dadPurchaseInfo.SelectCommand = New SqlCommand("SELECT * FROM Stock", conxMain)
Dim builder As SqlCommandBuilder = New SqlCommandBuilder(dadPurchaseInfo)
dadPurchaseInfo.Fill(dsPurchaseInfo, "Stock")
For Each dRow In dsPurchaseInfo.Tables("Stock").Rows
If CInt(dRow.Item("StockID")) = 2 Then
dRow.Item("StockCode") = "Re-Fashion(H)"
End If
Next
dadPurchaseInfo.Update(dsPurchaseInfo, "Stock")
Catch ex As Exception
MsgBox("Error : " & vbCrLf & ex.Message)
Finally
If dadPurchaseInfo IsNot Nothing Then
dadPurchaseInfo.Dispose()
End If
If dsPurchaseInfo IsNot Nothing Then
dsPurchaseInfo.Dispose()
End If
If conxMain IsNot Nothing Then
conxMain.Dispose()
End If
End Try
End Sub
