adding data to SQL from form textbox, a variable

[Rudy]

Hi all,
I know this is easy, just can't seem to get it. I have a windows form, and
a text box, with a value already in it. I need to add that value to a table.
It's just one value, so the entire row doesn't get filled. I have a
connection and all that stuff.

Private Sub btnPlaceBet_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles btnPlaceBet.Click
' Dim Myds As Footbet.DStable
' txbxCPwage.DataBindings.Add("txbxCPwage", Myds, "TableID.Pass")

Just looking for the code to pass this value to the DS.

TIA!
Rudy

Rudy,

I do not understand you, therefore I give you 2 answers, if you want to add
it to the databaset table, than you have to create an SQL insert command and
than use an SQLcommand.nonquery to update your database, that is all.

http://msdn.microsoft.com/library/de...QueryTopic.asp

When you want to add it to an item in a row in a datatable in a dataset than
it can be
ds.tables("thetable").rows(therownumber)("theItem" ) = "xxxx"

I hope this helps?

Hi Cor,
Thank you for your input. Let me try to explain a little bit better. I have
an answer to a formula that will show up in textbox1. I have 4 textboxs with
the same situation, except the formula is diffrent for each textbox,
therefore, four diffrent answers. In my table i have a column name textbox1,
2, 3, and 4, to match the information to the form. Anyone of the values in
the textbox need to be placed in the table, just 1 or 2 or 3 or all 4 at any
time. When the ENTER button click_event is fired, it needs to take the
values, put them in the approiate coulmns. I'm using SQL by the way for
this. So I'm not sure if I can specify which row it will go into, because it
really doesn't matter. the info will just keep adding to the next row. I
guess the row number would relate to how many times the ENTER click event is
fired. first click, row 1, second click, row 2. In addition, to make things
more interesting, I need to be able to have 5 client computers that has this
setup, going to one SQL server. The number of clicks would actually be total
number from all five clients. Right now I have column in the table to keep
track of which client is enter the values. But I thought about just make
duplicate tables, for the diffrent clients, not sure which would be better.
The max clients I may have is 100. I hope this make sense. Sorry for
rambling on.

Hello Rudy,

Your right this is actually easy but a little bit of code writing will be
involved.

First, Are you writing these values to existing records or are you creating
a new record based on these formulas.. Its not a big deal if which one your
doing or if your doing both..

You will need the following

SqlConnection
SqlDataAdapter
SqlCommandBuilder
DataSet
DataRow

Exp..

Dim objSqlConn As SqlConnection
Dim objSqlDa As SqlDataAdapter
Dim objSqlCmdB As SqlCommandBuilder
Dim objSqlDs as New DataSet
Dim objSqlRow as DataRow

objSqlConn = New SqlConnection(String of connection)
objSqlConn.Open

Dim strSqlTxt As String = ("Your query statement, usually a SELECT type")
**** Now this can be written in a manner as to return existing records or
where a field = Null so you nothing is returned, but you have a base for
adding new records.****

objSqlDa = New SqlDataAdapter("strSqlTxt", objSqlConn)
objSqlCmdB = New SqlCommandBuilder(objSqlDa)
objSqlDa.Fill(objSqlDs)

*** This next bit of code is for adding a record and filling the values ****

objSqlRow = objSqlDs.Tables(0).NewRow

With objSqlRow
.Item("TextBox1") = TextBox1.Text
.Item("TextBox2") = TextBox2.Text
Ect ect ect

End with

objSqlDs.Tables(0).Rows.Add(objSqlRow)
objSqlDa.Update(objSqlDs)

****Now if you have a query that is searching for an existing record you can
do the samw but with out adding a new record ****
objSqlRow = objSqlDs.Tables(0).Rows(0)

With objSqlRow

.Item("TextBox1") = TextBox1.Text
Ect, ect,ect ect..

End With

objSqlDa.Update(objSqlDs)

Well you might get the idea, if you have any questions feel free to ask...

Best regards,

Hi DuPont,
I am getting the following error - Object reference not set to an instance
of an object
This gets stopped at the objSqlRow = objSqlDs.tables(0).NewRow

I wrote the code out like you suggested, i didn't use...

objSqlDa = New SqlDataAdapter("strSqlTxt", objSqlConn)
objSqlCmdB = New SqlCommandBuilder(objSqlDa)
objSqlDa.Fill(objSqlDs) Then I did try it, but got a Null Value error.

I don't understand why I need a SELECT statement, when I'm doing an update.
I guess I'm a little confused.

Thanks for your patcience!

Rudy,

A fill is not an update, that is reading the data into the datast
A update is an update.

\\\something like this is a complete reading and updating,
\\\however there is needed a lot of checking etc with this.
\\\and therefore this is almost the most simple format.
dim ds as new datataset
dim SQLtxt as string = Select * from mytable"
Da = New SqlDataAdapter("SqlTxt", Conn)
Da.Fill(Ds)
Cmd = New SqlCommandBuilder(Da)
ds.tables(0).rows(0).item(1)="SeconditemFirstrowCh angedFromTextbox"
da.update(ds)
///

I hope that this helps?
