I'm just getting my feet wet with LINQ but am struggling to convert this SQL statement to LINQ.
Dim SQLString As String = "SELECT MESSAGE_ID FROM " & Schema & _
".PPM_TRANSFER_EMAIL WHERE TO_CHAR(IMPORTED_DATE,'YYYY/MM/DD') <= '" & _
DeletionDate.ToString("yyyy/MM/dd") & "' AND IMPORTED = 'Y' AND FILE_NAME LIKE '" & _
mb & "%'"
I have a Dataset that already contains all the data from the PPM_TRANSFER_EMAIL table so it seems silly to query the database again when I can use LINQ to query the dataset.
When i try to save the changes to my database i get the following error. (code is below)
System.Data.OleDb.OleDbException was unhandled

Syntax error (missing operator) in query expression '''system time'''.this is the error that appears
this is my code:
Dim sqlCmd As String
Dim x As Date
x = Format(Now(), "General Date")
[code].....
the fields in the tables are all text fields.is there any way to fix this error? perhaps it is in my query but i really cant find a solution.is there an alternative to get what i want my program to do?it is basically entering an ID number and finding the record with the same idnumber and putting the system time on the timein field for that record.
im trying to implement a basic 'verified by visa' section on my form. Basically, the user must enter their visa password and click verify. On button click, a database statement verfies whether the card number and password match what is on the form with the details in the database. (this works fine). Basically, if you get the password wrong you get an incorrect password error (this is fine). basically though, if a user enters a new credit card number which is not in the database, obviously no password will exist, so how do i accomodate this into my code? Atm im just checking whether the fields match, obiously if those fields dont exist i dont want the user to get an 'incorrect password' because the data doesnt exist yet, so i want the user be able to 'create' a new password for that card number.

View 3 RepliesIf I run a SQL statement or execute a stored procedure from SQL Mgmt Studio, I will get two tabs: Results and Messages.I am lookig to return EXACTLY whats in the messages (the tab I'd see in SQL Mgmt Studio)window to a string variable. Is there a property in ADO.NET (maybe in the command object?)that contains the messages returned from a stored procedure? I am using VB 2008.

View 2 RepliesI am writing a signout program in vs2008 using an access database.I have created forms and can call student and equipment info from the tables.I got the sign out part working and can add data rows to my table containing that information now I seem to be stuck in a stupid place. Signing the equipment back in I call the record to fill a form now all I want to do is add the date to the RETURNDATE column and save the record back to the DB and I am stuck at that point and cant seem to find the answer on the web.

I have a form with comboboxes, if the user doesnt select a value in the box I want a null to be sent to the database. The insert works fine, i look at the record in the db and see the null. The update doesnt work. gives me a n "Update statement conflicted with foreign key constaint....."
Public Sub Update()
TableAdapterCreate().Update(ID1, ID2, CType(cbox1.SelectedValue, Integer), CType(cbox2.SelectedValue, Integer), CType(cbox3.SelectedValue, Integer), CType(cbox4.SelectedValue, Integer),
[CODE]...
As I step through the selected value of the cbox 5 is shown as nothing (which it should be because the user didnt select a value for this combobox). I assume this needs to be a null instead of nothing to get written to the database. the combox boxes need to match a primary key in another table so sending a 0 would also result in the forieign key error since the related table does not have a 0 ID field.
I just made a code to convert data from excel to access.
I encounter an error every time that I try to make the convertion.
This is the error:

View 3 Repliesi have to update the values in my database some of them are integer, some string and some date (as you can infer from the formatting)

I am using this code to Add rows to a SQL database, and it adds the row to the SQL database if column 7 is not null. After it adds the row to the SQL database, it deletes it from the Access Dataset, and updates the Access Database. Sometimes double rows seem to get inserted into the database, so I'm thinking there is an error in my logic somewhere here.
Dim rowcount As Integer = AccessDataSet.AccessTbl.Rows.Count
Dim y As Integer = 0
For x = 0 To rowcount - 1
txtRow = AccessDataSet.AccessTbl(y)
If IsDBNull(txtRow(7)) = False Then

I get a "Syntax error in INSERT INTO statement" on the da.update line. The bulk of the code is copied from a working section of the program, I have just added the "newrow" stuff. I am pretty confident I have the names of all the fields correct.
i am working in windows appl vb.net 08. And i am working in Access DataBase.I have one Table Called "Person" . In this "Person" Table one Column Name Called "OtherName". In this Column binded in one of the Combobox in a Form.But the Problem is "OtherName" Column having the Null Values.Before i bind this Column to Combobox i want to convert this NULL Values to String. Why i need the values in STRING means , In my code i using this Combobox as a filter in SQL Query.If i didn`t change the Null Value to STRING , The Combobox SelectedText or SelectedValue is Showing Nothing. So i am not able to get the Record.
Whn i write a Sql Query to Combobox and apply filter in WHERE statement like Combobox.Selectedtext or Combobox.SelectedValue In "Selected Change Committed Event" then i should get the record in the Output right but unfortunatly i am not getting the Record. The Record Count in DebugPrint showing 0.

convert this C# to VB.NET? convert it manually (translators are not doing a proper job for this) or at least let me know step by step what is happening in this statement so I can do the approrpriate translation myself.

View 2 RepliesIt appears that VB in VS8 doesn't support/convert lambda expressions with a statement body. I'm using them in my C# application, but now must convert it to VB.I'm creating a whole bunch of controls dynamically, and I want to be able to give them event handlers on the fly. This is so I can build a dynamic user interface from a database. In the following code I'll create a form and a checkbox, make the checkbox control the form's visibility, add a few method handlers to the form, and then add the newly created checkbox to a pre-existing form/panel/etc. Handlers for the form, for instance, affect the checkbox:
[Code]...
I really liked the ability to create everything on the fly, and then let the objects handle themselves - I don't need to add any special functions that figure out which form is giving the close event so it can search for the right checkbox and update the checkbox - It Just Works (TM).
Unfortunately it needs to be converted to VB. What is the best way to convert lambda/anonymous statement bodies into something that will work in VB, especially when one needs to create many of them?

I currently have a problem attepting to update a record within my database. I have a webpage that displays in text boxes a users details, these details are taken from the session upon login. The aim is to update the details when the user overwrites the current text in the text boxes.I have a function that runs when the user clicks the 'Save Details' button and it appears to work, as i have tested for number of rows affected and it outputs 1. However,when checking the database, the record has not been updated and I am unsure as to why.I've have checked the SQL statement that is being processed by displaying it as a label and it looks as so:
UPDATE [users]
SET [email] = @email,
[firstname] = @firstname,
[code].....
I'm trying to update a specific record based off of a users selection. Regarding Entity Framework syntax, I'm not very familiar. Is it possible to achieve this SQL statement in Entity FrameWork?
