Committing Data To SQL From A Visual Basic Form
Jun 12, 2007
I have novice level visual basic knowledge using Visual Studio 2005 and have little knowledge of SQL using SQL express. I am attempting to create a SQL database which initially consists of a single table bound to a Visual Basic form for data entry. So far I have been able to bind a VB form to a SQL database creating a DataSet, DataAdapter, and utilizing the default binding navigator. I also seem to have functioning Stored Procedures.
The VB form is able to add data to the SQL table and I can toggle through the data while the VB app is running but when I terminate the app and load it again all newly added data is not available from the SQL table.
I have seen other strings on this subject and viewed many tutorials but they only bring me as far as I am. None of them address the concept of permanently committing data to SQL from the VB form. FYI€¦data entered manually into the SQL table is stored, just not data from the form.
Does anyone have any idea what is wrong?

Hi
I am developing a program on Visual Basic 2005 to a pocket pc, I want to make the SQLceconnection but It says that the file doesn´t exists, I use this code:
Dim conn As New SqlCeConnection()
Dim Recordset As SqlCeDataAdapter
Dim SQL As String
Dim ds As New DataSet
conn.ConnectionString = _
"Data Source = '.BDDclimatologicos.sdf';"
conn.Open()
SQL = "select [Provincia] from ZonasClimaticas"
Recordset = New SqlCeDataAdapter(SQL, conn)
Recordset.Fill(ds, "ZonasClimaticas")
lstboxProvincias.DataSource = ds.Tables("ZonasClimaticas").DefaultView
I have Dcilmatologicos.sdf on a folder named BD next to the folder of the executable, I don´t know what happends.
My database has one table "ZonasClimaticas" and a column named "Provincia" on that, my other question is:
Is this the right code to show that column on a listbox?
Thank you very much!

Of all the Visual Basic.NET data access books that I have purchased and all the Internet site example code that I have reviewed, none have had any good examples of multi-threaded VB.NET code doing data access.
I am trying to avoid the non-responsiveness in a VB app while a simple data retrieval from SQL Server 2005 is in progress.
If anyone knows of any book titles or web sites that have example code (good or not) of multi-threaded VB.NET applications doing data access against Microsoft SQL Server (7, 2000, or 2005) or even against Microsoft Access(TM), it would be very much appreciated if you could provide the book title or URL to point me in the right direction.
The more examples the better.
Thanks in advance.

I need help.
160821A network error was encountered while sending results to the front end. Check the SQL Server errorlog for more information.
I need help.
Our SQL Server is crashing. The Database is still recovering. I can not kill any Process when the Server crashed. I shoot down and restarted the server. Nothing to do. I can not access to the database. It is recovering. How long? I do not know. What can be the reason of the recovering? Nor the event log of Windows NT or the log files of the SQL SERVER can help me.
Here is a part of the log file
23216Arithmetic overflow error for type %s, value = %f.

Greetings,
Firstly, apologies if this topic is out of the scope of this board, but I am stumped.
Basically, we have an old Visual Basic 6.0 application which currently accesses an Access database, but which we would like to upgrade to an SQL compact edition database. I have created the database, but have so far turned up next to no details reagarding how to connect to the damn thing in VB6.
Can anyone help? Or at least point me in the right direction?
Many thanks,

I want to use Visual Basic to create DTS connection. In the example below a connection is created using an ODBC string. However, I would like to make the Connection's DataSource be an OLE-DB provider instead of ODBC. However, I cannot find any information on the syntax for using an OLE-DB provider as the DataSource.
Your help is appreciated.
Les
strODBCdsn = "server1" 'Create a DSN called SQL7 or change name
strUserName = "sa" 'User name assume same source and dest
strPassword = "" 'with the same Password
Set oConnection = oPackage.Connections.New
oConnection.ID = 1
oConnection.DataSource = strODBCdsn
oConnection.UserID = strUserName
oConnection.Password = strPassword
oPackage.Connections.Add oConnection

I'd like to be able to query a database to get the value of a
certain row. However, I'd like to save this value into a variable
and use them as I'd like, NOT nessessarily display them in a data
control such as a gridview etc. I've been able to find a lot of
information on binding datasourses to predefined data controls, but I
can't find anything on simply querying a database for values and using
those values to display a page as I want.My basic end goal is to create what's basically a shopping site like Amazon only for about 100 or so products.Thanks
in advance for any help. I'm just getting into Visual Web
Developer so please excuse my ignorance and lack of posts.

Has anyone experienced problems calling stored procedures that references syscomments.text from Visual Basic 6?
I have a stored procedure that finds all tables referenced by a specific stored procedure. It works well when I call it from SQL Server Management Studio, but there are cases where it does not find the tables when I call it from VB 6.
I've isolated the failure it to a specific condition in the WHERE clause:
SELECT @howfar = so.id
FROM SYSOBJECTS so
LEFT OUTER JOIN syscomments sc on so.ID = sc.ID
Where lower(so.name) = lower('storedProcName')
AND lower(sc.TEXT) LIKE '%' + lower('update') + ' ' + lower('tableName') + '%'
The call from VB works (finds the record) if
" AND lower(sc.TEXT) LIKE '%' + lower('update') + ' ' + lower('tableName') + '%' "
is omitted, and fails (does not find any records, no error is raised) if that condition is included.
I should also add that the VB Call does work for some combinations of stored procedures and tables.
The old SET NOCOUNT ON trick does not make any difference.

Let me get VERY specific.
This site has 40+ pages Using VWD 2008 (Studio 2008)
I have created in local IIS7 (129.0.0.2) http://cumc.lcl
Navigation.master, Web.config and Web.sitemap alll are structured
And all 40+ pages have been built.
NOW I added (using VWD) a sql server database named pagedata.mdf
With a table named: pages
and fields:
PageID - Primary Key (auto numbered)
pagename - nchar(30) exmp Default
hitcount - numeric(18,0)
createdate - nchar(15) exmp 04/18/2008
updated - nchar(15) similar to createdate
hitdate - nchar(15) similar to createdate
bottom of each page is to show 99999 visitors
and under that is to be Updated on mm/dd/yyyy
On pageload should accomplish the following increment the hitcount
field and save it and display it in HitLabel.text
Set UpdateLabel.text to updated field
Save the date the page was hit in hitdate field. (will only show when last hit)
The "tester.aspx" page now has:
<%@ Page Language="VB" MasterPageFile="~/Navigation.master" Title="tester" %>
<script runat="server">
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub
</script>
<asp:Content ID="Content1" ContentPlaceHolderID="head" Runat="Server"></asp:Content>
<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" Runat="Server">
<p align="center">This page is for various tests<br />and will NOT be site mapped.</p>
<p align="center"></p>
<p align="center">
Can this SqlDataSource be moved into Sub Page_load above?
How do I extract, process and save the Hit and Date data
for each individual page referenced by pagename field?
<asp:SqlDataSource ID="SqlDataSource1" runat="server"
ConnectionString="<%$ ConnectionStringsageConnect %>"
SelectCommand="SELECT * FROM [main] WHERE ([pagename] = @pagename)">
<SelectParameters>
<asp:QueryStringParameter Name="pagename" QueryStringField="thispage"
Type="String" />
</SelectParameters>
</asp:SqlDataSource>
</p>
<p align="center">
<asp:Label ID="HitLabel" runat="server"></asp:Label>

This problem only occurs after deployment, not when debugging. In the table I am having a problem with I have an ID field designated as the primary key with the identity increment set to 1 and the identity seed set to 1. There is no data in the table when deployed. I can add records to the datagridview control but when I try updating the dataset I get this error indicating that the ID field already has a value of 1 present. If I close the application and re-start it, the exception no longer occurrs when I update the dataset. I am including the code to update the tables incase something is wrong there. Any suggestions?
Private Sub UpdateMemberTable()
Me.Validate()
Me.TblMembersBindingSource.EndEdit()
Me.TblMembersTableAdapter.Update(Me.ChurchFamilyDataSet.tblMembers)
Me.TblMemberDependentsBindingSource.EndEdit()
Me.TblMemberDependentsTableAdapter.Update(Me.ChurchFamilyDataSet.tblMemberDependents)

Hi all, I have a var called sEP which contains a number. The problem I have is calling that var during an SQL query within Visual Basic. To test the update string I wrote the following query and simply told it to enter the text "Five Stars" on the row which contains the entry '1' in Episode Number column. It works fine. UPDATE JackBennySET Rating= 'Five Stars'
WHERE ([Episode Number]= '1') But how do I replace the '1' in the query with the var sEP (which will contain the actual number I want the query to run against)?I have tried various suggestions from sources including:UPDATE JackBenny SET Rating = 'Five Stars' WHERE [Episode Number] = '" + sEp + "'However, they all fail to update the database at all which makes me think the syntax is incorrect.Any help is very appreciated (I have been seeking help in various places for 2 days now) - I always send small paypal tips to people who help me on forums.
