asked on

stored procedure stopped working

I have created the sp but something is going on with the schema i think as its underlining red. i selected modify here so you could see the sp code. I manually ran select query to check rows exist

use Dictionary
select [word]
from [TblWords]
where [Word] = 'bioflex'

but when i call the visual basic code the object is returning no data the data is from a combo and the message box shows that looks ok but my call might not be:
    Private Sub CBCWSelectedItems_SelectedIndexChanged(sender As Object, e As EventArgs) Handles CBCWSelectedItems.SelectedIndexChanged
        Dim selectedIndex As Integer
        selectedIndex = CBCWSelectedItems.SelectedIndex
        Dim selectedItem As Object
        selectedItem = CBCWSelectedItems.SelectedItem

        MessageBox.Show("Selected Item Text: " & selectedItem.ToString() & Microsoft.VisualBasic.Constants.vbCrLf &
                        "Index: " & selectedIndex.ToString())
        ListMatrix.DataSource = GetMatrixData(selectedItem.ToString()).AsEnumerable().Select(Function(r) r.Field(Of String)("Word")).ToList()

        ListMatrix.Refresh()
    End Sub

Open in new window



 Public Function GetMatrixData(ByVal StrWordIn As String) As DataTable
        Dim StrProcName As String
        Dim StrWord As String
        StrWord = StrWordIn

        dtMatrix = New DataTable
        Dim connectionString As String = ConfigurationManager.ConnectionStrings("Dictionary").ConnectionString

        If OpTag.Checked = True Then
            StrProcName = "usp_GetMatrix"


            Using connMatrix As New SqlConnection(connectionString)

                Using cmdMatrix As New SqlCommand(StrProcName, connMatrix)
                    cmdMatrix.CommandType = CommandType.StoredProcedure
                    connMatrix.Open()
                    cmdMatrix.Parameters.AddWithValue("@WordVar", StrWord)
                    Dim readerMatrix As SqlDataReader = cmdMatrix.ExecuteReader()

                    dtMatrix.Load(readerMatrix)

                End Using
            End Using
            Return dtMatrix

        Else

        End If
    End Function

I checked the query and it is working fine.

What is the value of 'OpTag.Checked' in the function GetMatrixData before SP is called?
