I've tried a few different methods I could find in order to connect my VB .NET program to a book store's database. While I've been able to connect to it and display the contents of its tables in a DataGrid, I need to be able to search the tables and display specific records, depending on the contents of appropriate the adjacent text boxes.[code]This is a code I've used for a very similar process, just really aims to search a different field in the table. If this is easier to adapt into a code that allows searching and producing specific records in a database, please use this one.

I have a program that connects with an access database and displayed the results of a query in a series of textbox which are created at runtime. This all seems to work but the problem is with my next, previous buttons they just dont seem to work now and they did before. There must be some kind of problem with my code.
Code
Private Sub single_record_View_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim strEmployeeDepartmentLocation As String

I've created a database in Access 2007 and connected it to Visual Basic 2008. My database have tables Coachee and Coach. Details of Coachee are displayed in one form and there's a button that when clicked will show details of the Coach of that particular Coachee in a another form. If the Coach is not in database, user will be prompt to insert a new Coach record. Problem is, when saved, the newly inserted record will not be displayed and i have to exit and rerun the program, only then the record will be displayed.

I used following code searching records from a table in MsAccess and displaying in a Listview and it is working fine with the search criteria based on Discription.
CODE:
I also tried the above code to search records on the base of CustId and it worked fine too.My table DailyTransaction in MsAccess is as under:DTDate, DTTime, CustId, Description, Quantity, Price, Amount, AccountNumber, Name
Now I want to Search records on the base of Date I tried the following but it did not work.
Dim cmdText As String = "SELECT * FROM DailyTransaction WHERE DTDate=' " & TextBox1.Text & " ' "
Also i want to make following sort of query to retrieve data between two dates and to display the sum of amount group by DTDate. I could sketch following query and deifinitely it is so wrong with Syntex.Select * From DailyTransaction where DTDate Between textbox1.text AND textbox2.text Group By DTDate AND SUM(Amount)

I have a DataGridView (dgv) on a Windows form (VB.NET) which is bound to a datatable. One of the bound columns is a an ID (Foreign Key) to another datatable. All I want to do is Hide the ID column and populate an unbound column with the Name (ParmName) for the user. I searched the foreign value in the datatable and retrieved the information. I set the Value of the cell in the Datarow. All works well, but does not display. The cell accepts the value...I can even Debug.Print the values to the console. They are there just nothing displaying in DataGridView. Nothing odd about DataGridView. Should be straight forward...
My Code
,
Dim dtParm As DataTable = MyDataSet.tblParameter
Dim dgv As DataGridView = Me.dgvResultNum_DataGrid

I am trying to count the number of records that match Course_ID = 1 in a table.
Here is the expression I am using
=Count(IIF(Fields!Course_ID.Value="1",1,0))
also
=Count(IIF(Fields!Course_ID.Value=1,1,0))
I always get the number of records in the whole table and that is not what I want.

I'm having a problem setting the maximum number of records that can be saved into Access. The maximum allowance is to be 10. Records are being pulled from a listbox. The whole problem is that if the listbox has 7 items and my table already has 5 records, it still records them, making a total of 12. What I'm looking for is a way to trap that to a max of 10.[code]...

I'm creating a number guessing game. [Code] Textbox1.text refers to the answer input by player. There are two labels for displaying the range of the answer within. Label1 and Label2 refer to the lower limit and higher limit respectively. If the input value is smaller than the answer, the label1 will show the number that input into texybox1. If the input value is larger than the answer, then vice-versa. However, the program doesn't work as my expectation. Once I input the answer, the MsgBox doesn't appear. When the input value is smaller than the answer, the label1 doesn't show the input value.

I am working on a program that will display the number of storms in a specified year. This program uses a text file with years 1990-2010 and the number of storms for each year.
txt file:
Year 2010
6
Year 2009
3
Year 2008
8
Year 2007
15
Year 2006
10 .....
A user selects a year from a ComboBox (cboYear) and the program displays the number of storms using a label object (lblNumberOfStroms) for that year. The user then can click a button (btnDisplayStatistics) and the program will display using a label object, the number of storms for that year. This seems like a simple application but I am having trouble grasping the use of arrays concept.

I'm creating a report where I want to send a parameter for the number of records to display (I do not want to select the number of records in SQL) I have created a parameter field (?topN) and set the group to use this value which in design mode works well however when I try to set this parameter in vb.net code it does not work. The field which also displays the value shows the parameter correctly though.
