url...How do I reference a query in a DataTableAdapter so that I can put the values gathered into a Textbox? I'd like them to all go on their own line in an order like so: LastName, FirstName, GradYr: MP1_Pts: MP1_Comments; MP2_Pts: MP2_Comments.Can someone guide me in the right direction here? This is the final step I need to take in creating my program.
how to take a query that returns a single row of data and load that data into textbox controls.I know about ExecuteScalar but it is only good for a single column of data from the query.
I want to query an access database with variable data defined by the user. The "Search" criteria would be in a textbox. I made a query like
SELECT askID, Question FROM chita WHERE (askID LIKE 'Textbox10.text%') and referring to this query as
Form1.ChitaTableAdapter.searchrec(Form1.ChitaDataSet1.chita)But id does not take the value of the textbox, instead it takes the Textbox10.text as a value. Is it possible to refer to it like this, or should I Linq?
I'm using a pattern of buttons verticle, & horizonal, to produce a 2 dimensional matrix (6 deep, 25 wide .) The sequence is repeating, but offset from horizonal line to line. the values are 1 thru 12. there are corresponding files in the "My.resources." file carrying names related to the buttons. If the "my. Resources" filename is say.., "1,3,4,6,8,9,11,12 " & the buttons pushed have produduced the string "1","4","6" then the prestated file carries all these values, and therefore should be selected. All integers of the textbox list must be present in a "my.resources" file to show the file. There will be multiple files in the resource file that will fit. (My ultimate intention is to show all files that fit, somehow. I'll have to, eventually. I'm still writing this, and changing it constantly. )the question is, "How do I get the computer to link the textbox integers to the resources files? Textbox = "1", "4", "6" to My.Resources.1,3,4,6,8,9,11,12
Right now I have an array that is unparsed. One of its elements goes something like this:
"Blah, 555-5555"
So it's a name and a telephone number separated by a comma. The instructions I have tell me to use a query to put the information in the array into a data grid view in two columns, one for the name and one for the telephone number. I don't know how to isolate each inside a query.
If I have a query dataset in MS Access (or SQL query) that results in a table with column A as such:
A 500 400 300
How can I hav Column B show growth rates such as B2 = (A2/A1) where A2 = 500, A3 = 400, and A4 = 300, and so on successively (like one can perform on an excel sheet) as such:
B 1 .8 .75 (Columns shown adjectly below for clarity)
My issue is with getting the attribute values. I tried this: For Each xattr As XAttribute In attr cboBrandChoice.Items.Add(test.Value) Next
However, I keep getting the following error: {"Unable to cast object of type '<GetAttributes>d__8' to type 'System.Xml.Linq.XAttribute'."} I'm new to using Linq so this error isn't making a whole lot of sense to me.
I want to check some values in a sql db without populating controls. I can select the row i want, but for some reason my mind then hits a blank, maybe its because its monday.I want to check a few bit fields in the row and if 1 - do something, if 0 do something else. In this case depending on which bit fields are set to what, id like to enable/disable various controls on my form.
Heres the code i got so far, but as i said then i drew a blank, and i may be going about this completely wrong:Dim SQLcon As New SqlConnection("server=DEVSERVERDEVSQL;" & _
"integrated security=sspi;database=WDA_SQL") Dim SQLqry As New SqlCommand("SELECT * FROM Users WHERE (Username = @Username) AND (Password = @Password)", SQLcon) SQLqry.Parameters.AddWithValue("@Username", UsernameTSlbl.Text)
how to store or return multiple queries result values into multiple variables.. I'm using a query that return 4 columns but how to.. individual store those results into 4 separate variables.. here is my code

I have a table which fields are Date, No, Turnover, TotalWin, Opencredit, Handpay, Billin, gamesplayed and I am trying to write sql in vb.net that will show me previous day value but I cant. Here is what I am trying to do.

Ok Thomas I am not able to give correct answer to your question because first time in my Life I am trying to write sql. I was doing this with MSAccess and it was easy. Now I am getting pretty simple error I think with this code but I can't find solution again. What is wrong.
I have a sql query with that adds numerical values from different table to find total for a shipment. When I execute this query, it works fine for the first record but rest of the records show null value when I know there are records present. SQL pros take a look if there is a problem with my syntax.
Im having an issue with a certain query,Dim nwLat As Double Dim Ssql As String
nwLat = nwLatHidden.Value Ssql = " select * from customer where latitude < " & nwLat TFRcount.SelectCommand = Ssql TFRcount.SelectParameters.Clear() TFRcount.DataBind()
All it does is refresh the page and does nothing; it should populate a chart. However when I replace nwLat with a value (eg where latitude = 56) it works perfectly and populates the chart. Any ideas what's wrong with nwLat?
EDIT: I switched nwLat to long and it works; however it only takes the number up to the decimal and ignores the rest. Any way to fix? (eg as double 56.764746 and long 56)
This is the current code. Rather than put in this 100 times for each number, What would be a better way? Have had a go myself but can't get it to work.
I'm creating a Multiplayer LAN game in VB 2008 here is what I wanted to do I created a textbox named txtbuttons.text. If I inputed a value, for example 23856 in the textbox.The Values will be distributed in different textboxes.
example Value of txtbutton.text = 23856 2 will be distributed to txtAns.text 3 will be distributed to txtAns2.text 8 will be distributed to txtAns3.text 5 will be distributed to txtAns4.text 6 will be distributed to txtAns5.text

I have 2 tables Table1 with columns [BId,Name,Amount] Table2 with columns [CId,BId, ExpenseType,Expense]. BId Is the foreign key in Table2. The Amount field in Table1 is always higher than Expense in Table2. I need to update the values of Amount (increase or decrease) based on value of Expense and I want to do it in single query in LINQ. Eg If the Expense has to be updated with 200, I would decrease(negate) Amount value with 200. If Expense is reduce to 100 then the Amount is increased by a value of 100.
I am using a where comparer in the below snippet from my function.. I need to order or sort the returned items by one of the columns... I tried using .OrderBy(function(f) f.regDate) but that dont work at all... The part of the function in question looks like this:
I've tried different approaches to query a simple xml and compare one of it's values but none of them worked well.
Consider the following XML structure: <?xml version="1.0" encoding="iso-8859-1" ?> - <Shops> - <Shop> <text>Northampton</text> <value>NN</value> <currentdate>050809</currentdate> <labelcounter>1</labelcounter> [Code] .....
I have the shop name in a drop down list which is ShopsDDL and it's set to autopostback. What I want to achieve is: On postback, check for a xml node where node's text = shopDDL shopname And retrieve also this node's currentdate and label counter. Rhen, if the node currentday = today then increment labelcounter by 1 Else set labelcounter = 1 and currentday= today My problem is the XML query, I can do all the logic as soon as I manage to retrieve data from the XML.

I am fetching all departments and their sales, average, count from the ReceiptLine, Receipt, ReceiptDiscount tables. The problem i am facing is, if i remove where discount > 0, I am getting null exception. But if I include that, then I only get sales that has discount. How would I write query that bring all sales less discount (if it has one).
It errors on the executenonquery. Says the column rootforestname can not be null. i don't under stand why it does not fill in the value in the command text.
I am getting the above error in my code. I've searched the net (on this site and others) for a solution to this problem and it seems that its either something to do with a field name being a reserved name ie. Date, Time etc.... or its missing (') or (") in the SQL command. ive tried both these solutions to no avail.

I am trying to Query a table with data from another table and return a filtered result
Dim i As Integer = 0 For Each lrow In dtlist.Rows() Dim lat As Double = dtlist.Rows(i)("Latitude") 'CDbl(Me.SubjLat_txt.Text) Dim lon As Double = dtlist.Rows(i)("Longitude") 'CDbl(Me.SubjLon_txt.Text)
[code]....
Obviously doesnt work but the idea is thats the Value i need to put in the Value Column of dtlist In short the project, loops through one table(dtlist) of address's and gets the distances of it from the address's in the second table(dtsold) then gets the higest value from dtsold within a certain distance?
Hpw can I pass multiple values from same column in a query? I am using vb.net and sql server database.
With my query an exception is generated saying that @booking_date has already been declared try a different variable....
My query is:
Dim da As New SqlDataAdapter("select * from Bookings where booking_date Between (@booking_date AND @booking_date) AND booking_time Between (@booking_time AND @bookinbg_time) AND game = " & x, con)
I am having trouble using the values that were selected from the dropdown list. How would you reccommend passing the selected values from the view?Ideally, we want to use the selected dropdown values to determine a query.
here is my code. dont seem to know whats the problem. i have 12 data fields in access excluding the ID field.
Dim strCon As String = "Provider=Microsoft.jet.oledb.4.0;data source=C:UsersdexterDocumentsdesktopcsci14databaseMuseum-final.mdb" Dim dSet As New DataSet
i am making a simple testing application within visual studio 2010, thought im gonna be direct. in ms.acces i made a database with a few tables, this one is about the table : leden. the error indicates that i simply do not have enough values to insert into the table and i think it has to do with the ID(autincrement in acces)
