I have a month and a year dropdownlist which give me the following string 01/2012 The date format in my db is "2012-01-01 00:00:00" but when I select an individual date and put it in a message box it converts to "01/01/2012"
I've altered my select statement below to reflect the converted date. However Im still not given the correct details. Any ideas? Is there a particular format that I need to use when dealing with a timestamp field? Can I even use the "Right" function in a select statement?
Dim newRecordDate As String = val1 & "/" & ComboBox2.SelectedValue Dim sql2 As String = "Select CatA, CatB, CatC, Cost, Currency, MarketingCode, Comment, RecordDate from vw_tblP_Usage_Details where puid = '" & puid & "' right(RecordDate, 7) = '" & newRecordDate & "'"

I've got a query which returns all invoices and credit notes for a given client, in a loyalty structure query where I need the total value of the points the client achieved through invoices, minus those that was forfeited by credit notes. Now I start my query like this (There are more unions in the query, this is just the first part)

i want to use a if, then statement in a where clause in linq to sql. Is this possible? I'm trying to achieve the following:
[Code]...
I'm trying to only add the And If if intLink_pk > -1. If it = -1, then i don't want the and clause at all. Is this posssible within the linq to sql itself?I understand i can write 2 entirely different selects, but if I can't get this done, I may have to write about 50 of them as I want to use multiple Ands if certain conditions are met on the form, such as chk boxes etc.

Say I have this in VB.NET:
Dim executeB As Boolean
Select Case myVariable
Case "a"
'some code
Case "b"
'some code
Case Else
End Select
If myVariable is "a", control will go into the first case statement. Now let's say if myVariable = "a", but inside a's case block, I find that executeB is true, is it then possible to jump to the second case?

I'm building a dynamic query in my ASP.NET MVC project by the following: [code]Where basically the strWhere is a string that I build up a dynamic filter depending on what the user selects to search on.This works great until I need to add a date comparison to the date clause.[code]Which will end up as:"SELECT VALUE userInfos FROM MyDBEntities.UserInformations AS userInfos Where userInfos.BirthDate <= 10/09/1992"..But when i try to execute the query with the ToList whenever a date is in the where string i get the following error:The argument types 'Edm.DateTime' and 'Edm.Int32' are incompatible for this operation. Near WHERE predicate, line 1, column 103.

I am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?

i have to convert a visual basic 6 program to the visual basic 2008. i used the wizard that is provided to upgrade but that just doesn't work. It comes up with many errors. most of them are End of statement expected and Number of indexes exceeds the number of dimensions of the indexed array. I really don't know what to do with them and i have to fix them in order for it to run.

End A statement which as far as i know doesn't close you program properly and hides errors. Right now i'm being forced to use end because i don't know how else to close my program properly. I'm not sure where my problem is but some of you should be able to fix it. I'm trying to make a game using directx with a game loop. This code is the skeleton of what i'm making.
Public Class Form1
Private ProgRunning As Boolean = True
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Me.Load
Me.Show() 'Make the form appear
Me.Focus() 'Give the form focus
[CODE]...
This code runs alright because end is being used but if you rem end out the error which it's hiding comes out. The error is "Object reference not set to an instance of an object." I'm not totally sure but i'm guessing that the error is refering to the form.

I got a table related to another table by orderref. I need to know what should be my SQL adapter command if I need to take some information from one table and some from another where orderref = "" or should I be making two separate SQLs?
I used to have this when I had only one table:
myStr = "select * from orders where Orderref='" + txtorderref.Text + "'"
Dim sqldaHistory As New SqlDataAdapter(myStr, nwindconn)
sqldaHistory.Fill(myDataset, "orders")

In my Form1 i have a datagrid with coulmns: CarName , CarModel , CarColor , CarOwner (there are a lot of data).
I added queries (textboxes that the user writes in text) that can "filter" data when the user want to choose specific CarName or specific CarModel.
textbox1 = CarName
textbox2 = CarModel
textbox3 = CarColor
textbox4 = CarOwner
If the user writes text in TextBox1 then the data shown in the DataGrid is filtered.What if the user want to choose also (!) a carOwner? I know how to use AND statements, but if the user didn't specified a carOwner non of the data is shown although there are this kind of data.

What is the best way to validate whether or not information exists in a datagrid. Let me give a situation.
What I'm trying to do here is allow the user to search and sort the dgv based off of the character or string that is he/she inputs into a textbox. The things I want to validate are:
The textbox is not blank, and if not blank has valid information. (easy enough)
The dgv has actually been populated from the dataset!!!!!
The second I can't seem to nail down, regardless of what I use. I have tried using rowcollections, columns.count(), cell, item, and a few other properties all of which either get skipped over by my if statements or throw an index is out of range error.

I'm trying to refresh the datagrid after using the SQL UPDATE statement. The data changes physically in the database but the datagrid is not affected. The data is changed only after i restart the program.
How can i get the datagrid to refresh or update? I have tried using, among other code, the refresh() method, but it does not work.

I am still having issues with the combo box. I have the correct query. I have four tables in MS Access. I need to create a form in Visual Basic that has a combo box and a datagrid. The selection from the combo box will display all relevant information about that person on the datagrid. For example, if I select John Doe (from the combo box) the datagrid should display: [Code] How do I add John Doe to the combo box and link this query to it, when upon being selected, it displays the result in the datagrid?

I'm trying to run an INSERT statement to pass data from a datagrid to a table I have on my database. The problem I have is that the table has 6 columns and the datagrid has only 3. So I only want to pass those 3 columns but I get the error that the other 3 columns does not accept null values. I need to change the columns to accept null values. The other problem it is that I can't pass more than 9 records, if I have more than 9 record on the DataGrid it says "object not set as an instance of a reference" and it only add 9 records if I have more than 9.
Dim RowCount As Integer = datagrid1.Rows.Count - 1
Dim ColumnCount As Integer = datagrid1.Columns.Count - 1
Dim RowIndex, ColumnIndex As Integer
Dim myconecction As String
myconecction = My.Settings.DataSource
