I am not sure how to create a class to insert data to ms db. I want to create parameters to 10 and then call from my Form1.vb to insert data. PleaseSee my sample below.


vb classe

1. Insert_DB class


public shared sub Insert_data(byval orderdate as string, byval address as string, etc)



...
...
...


mycon.open

mycon.createparameter(10)
mycon.addparameter(0, "@orderdate", orderdate )
etc

and then

mycon.executenonquery("my storeprocedure", commandtype.storedprocedure)



then in my VB form1.vb


call Insert_DB

dim test as new Inset_DB

test.orderdate = "03/16/2011"
test.address = "123 test st...."

at the end then insert data to db

Hi,

Ok, first of all, in you code example you are declaring your funciton as SHARED (this will mean that you want to call the function without an instance of the class), but you want to use it by making an instance like this

dim test as new Inset_DB

test.orderdate = "03/16/2011"
test.address = "123 test st...."

So, if you want to pass parameter like that, your function should not be shared.

Besides that you can add Properties to your Class, so you can assign the values to them, and your Insert_Data function should not receive any.

Your class would be like the code attached

Hope that helps


Public Class Insert_DB

    Public Property OrderDate() As String
        Get
            Return strOrderDate
        End Get
        Set(ByVal value As String)
            strOrderDate = value
        End Set
    End Property

    Public Property Address() As String
        Get
            Return strAddress
        End Get
        Set(ByVal value As String)
            strAddress = value
        End Set
    End Property

    Public Function Insert_data()

        '...
        mycon.open()

 
        mycon.createparameter(10)
        'Assign the Properties to the Parameters like this
        mycon.addparameter(0, "@orderdate", Me.OrderDate)
        mycon.addparameter(1, "@adress", Me.Address)
        '...

        mycon.executenonquery("my storeprocedure", CommandType.StoredProcedure)


    End Function

End Class
