Getting The Error "Parameter @ID Has No Default Value"?
Apr 5, 2010
I have a button that is supposed to display the next row in my database, however Im getting the error "Parameter @ID has no default value"I can make my code work without parameterized queries but Im trying to make it work with them...So Im sure there is something wrong with my code, obviously
Private Sub btnNext_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnNext.Click
txtID.Text = txtID.Text + 1
Dim ds As New DataSet()[code].....
If I change my sql statement to
WHERE ID = "& txtID.Text &"
Then i can get it to work fine, but I hear that isn't good programming.

I am working on a very simple application in Visual Basic 2008 Express.
The program has a Listview where I display the "DisplayName" field, the user clicks on a name and this should fill 3 text boxes. The code is:
strSQL = "SELECT FName, LName, DisplayName FROM tStaff WHERE DisplayName=@DisplayName;"
Dim conn As New OleDbConnection(strConnString)
[Code]....
This produces the error "Parameter @DisplayName" has no defaul value"
The value of the variable "strDisplayName" is correctly captured.

I'm having some difficulty with some code to update an Access DB. I keep getting "Parameter @ParamName has no default value" Renaming the parameter in both the SQL statement and the parameter.add, moves the error to a different parameter but it never goes away.

im using data bound item with my combobox and this error pop up.
Parameter @UserType has no default value.
when i set the value,it stated that
"The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again."
should i edit my usertype column in my database or there have another solution?

I want to include an optional parameter in a function statement that is of the type Unit. For example:
Public Shared Function NewTable(Optional ByVal TableWidth As Unit) As Table
Optional parameters require a default value, but I cannot figure out how to set a default value for a Unit type.

We have a legacy component that has been converted from VB6 to VB.Net.The VB component was called from an ASPX page using Request("param") to pass optional parameters to function calls. That means the value is null/nothing if the parameter is not present.The parameters were then added to an ADODB call of a store procedure using Parameters.Append.When used from VB6 missing, Request("param") values were coerced into empty strings when passed to the VB6 component. This meant that the ADODB call was satisfied (for required parameters).When the code was ported to VB.Net, the null Request("param") values are now passed as null values (VB nothing?) and Parameters.Append skips adding the value if it is nothing. This caused the stored procedure calls to break as a required param was missing.
If we change the component's function parameters to be optional and have paramname as string = "" defaults, will a null/nothing value be converted to an empty string, or is null/nothing treated differently to a parameter being simply missing?

I have a problem during defining a Sub routine in VB.Net. I am defining a sub routine which is as under
Private Sub ActivateControls(rdbutton as RadioButton, Optional txt as Textbox, Optional txt2 as Textbox)
End sub
When I call this sub routine It gives me the Error that Each Optional Parameter must specify a default value. So, Here I can't understand that what can be the default value of a textbox. What default value I can use here to remove this error.

I think this is a pretty basic question, but I just want to clarify. If I have a variable with a null value, and pass it as a parameter that is optional, will the parameter get the null value, or the default value?
dim str As String = "foo"
dim obj As Object
//call 1

I am trying to do an insert into a table called Policy. I keep getting an error that says parameter @Split has no default value. To try and resolve the problem, I set the default value of the split field (of type text) in the Policy table to "0" in Access 2007. I am passing in the value of a string "0" into the parameter before the insert statement executes.
Dim connection As OleDbConnection = PaulMeadeInsuranceDB.GetConnection

Dim data As Byte() = DirectCast(sdr.Item("Image"), Byte())
Dim ms As New System.IO.MemoryStream(CType(sdr.Item("Image"), Byte()))
PictureBox2.Image = Image.FromStream(ms)
After reading many forums and trying the different examples, when I try and load my image from the database I get the "Parameter is not Valid" error.Im using VB 2010, SQL Server 2008 R2, and the data type is Image. I do not have access to the source code that is used to save the picture to the database, just access to tthe data in the db.The code I have included is the code I use to retrieve images from my db which stores the pictures as Image.
