I double check the query and it is still throwing the error..
sql = "INSERT INTO " & tbl & " (userName,userPassword,userAccessLevel, "
sql = sql & "userDateCreated,userFirstName,userMiddleName,userLastName, "
sql = sql & "lastUpdateDate,lastUpdateBy) "
sql = sql & "VALUES (@u,@p,@lvl,@dateC,@Fname,@MName,@LName,@lud,@lub)"

I have been stuck for a long time on this simple but obtuse message "Must Declare the Scalar Variable"
I have a vb.net and SQL code that inserts data into a simple table. It works OK with sample data, but when I try to use a parameter (insertcommand.Parameters.Add("@ID", SqlDbType.Int, 3).Value = 50) it gives me the error. If I replace the @ID with just a number it works.
Eventually .Value = txtid.text if I can get the parameter to work.

Solution at the bottom. I receive the following error when trying to update records: Must declare Scalar Variable @PaymentTermID Problem is, @PaymentTermID should be defined already in the Update parameters. The 2 functions for onrowdatabound and onrowupdate are tweaked versions of the ones found here for the DropDownList: GridViewRow.DataItem Property. Delete works fine. No new lines are added, just names changed around. I am not exactly used to working with asp objects.

I have been debugging my code for a while and looking at posts in other forums, but it seems to be that everyone has a different problem than mine and what works for them will not work for me.My dropdown list is supposed to filter a gridview by choosing all the Companies that are associated to a certain product. The solution I have found online is that most people did not have DataKeyNames set in their gridview. I do have this set, but not to CompanyID. It wouldn't make any sense. So I have no idea what I am supposed to do since this is the only answer I have found.
<asp:DropDownList ID="ddlCompany" runat="server" DataSourceID="dsCompanyFilter"
DataTextField="CompanyName" DataValueField="CompanyID" AppendDataBoundItems="true"
AutoPostBack="true">

This seems so basic but I've been struggling to find a solution! I have a web page that take user data from aspx textboxes. Upon hitting a button, the click event submits the responses to a SQL table. Seems easy.I'm using VS10, dev express and VB code. I have established my datacontext class using LinqToSql...In a nutshell, the code is as follows...within the click eventNote that "database" was earlier defined as my datacontext sql connection, "Request" tablee
Dim vname As String = AspxTextbox1.Text
database.executecommand("INSERT INTO [Requests] (ContactName) Values (@vname)")

At first I was using this as an extension method to update my detached entities...
Public Sub AttachUpdated(ByVal obj As ObjectContext, ByVal objectDetached As EntityObject)
If objectDetached.EntityState = EntityState.Detached Then
Dim original As Object = Nothing

Everything has been working great until I had to update non-scalar properties. Correct me if I am wrong but that is because "ApplyCurrentValues" only supports scalars. To get around this I was just saving the FK_ID field instead of the entity object relation. Now I am faced with a many to many relationship so its not that simple. I would like to do something like this...
Dim Resource = RelatedResource.GetByID(item.Value)
Condition.RelatedResources.Add(Resource)
But when I call SaveChanges the added Resources aren't saved. I started to play around with self-tracking entities but it seems they cannot be serialized to ViewState and this is a requirement for me.how to either save my many to many relationships or serialize self-tracking entities?

I have a form with 2 controls, a textbox and a button. The user will type text into the textbox and then when they click the button the text that they entered will be added to a List Collection. You can see the code below. There is just 1 problem. Where would I put my declaration of my List Collection so that it holds the values and does not start at the first element everytime the button is clicked?[code]

I have searched online for a few hours to try to figure out how to do this, but nothing I found really makes sense, so could someone please tell me, in a simple way, how to do this?
Let's say I have a text box that the user fills out, named textbox1. And I have a combo box, named combobox1, which contains the choices A, B, C. And then I have a button named submit_button.
Each time that the user clicks submit_button, I would like to dynamically create a new variable. This variable should be named the same as textbox1.text, and should contain the value of combobox1.
For example, if the user types "blue" into textbox1, and chooses value "C" from combobox1, and then clicks submit_button... then the following variable should be dynamically created, like..Dim blue as String = "C"
And then, after that, if the user types "red" into textbox1, and chooses value "B" from combobox1, and then clicks submit_button... then another variable should be dynamically created, like...
Dim red as String = "B"
And each time the user submits new information into the textbox and combobox, a new variable should be created.Is it possible to have the program automatically create variables like this? If so, how?
My actual project is much more complicated than this, of course, so the above is just an example. But if I could figure out how to solve the problem in this example, I could figure out how to solve the entire project.

I am working on an alarm system software, which is SMS-based. I am using a GSM modem to receive the SMS when a client's premise security devices are triggered. The types of SMS text received will be like for e.g. "fire alert"(when devices triggers), "fire clear"(when devices are 'reset').
My program can detect real and false alarm, it works this way, i will input a premise site-map on a picture box at the main GUI, i can then create buttons at run-time and drag them to the respective position on the map. The buttons created have their text set as the client's block number referred to the database. So basically, a button represent a client. When a device in the client's premise is triggered, a SMS will be sent and my GSM modem will receive it, process the SMS and the button representing the client will start 'flashing' showing that the client's premise is under danger. Then when the button is clicked, which acts as an acknowledgement, will display the client's information on labels and turning that specific button to red color. Finally, when the device is 'resetted' in the client's premise, it will send another SMS to my GSM modem, after processing, the button will be back to normal.
But my program has detect false alarms also, the first part is similar to mentioned above, client's premise security device triggers, SMS sent, SMS received by GSM modem, process SMS, button 'flashing'. Secondly, if the alarm is false, it will be automatically 'resetted' or the client may 'reset' it, then a SMS will be sent to my modem, turning the button to 'flashing' green in color. when 'acknowledged' will display the client's info and the button will become normal.
The problem here i am facing is during the processing of the SMS, because the real and false alarms both will receive the 'clear' SMS when during some stages, but the functions are different and of course the 'checking' for both functions will be different too. The problem occurs at the checking process whereby the 'btn' variable is not detected.
'Try
'AT commands to receive SMS
serialPort.Write("AT+CMGL=""REC UNREAD""" & vbCrLf) 'set command message format to text mode(1)
