Create New Class For Each Procedure?
Jul 23, 2010
All I want to do is learn how to create a class procedure. And then. How to call it. As an example, A + B = C is the procedure. I would create a class. Right? Then do I name the procedure and put it in the class? Or create a new class for each procedure? Then I would want to, on a local level, substitue values for A & B to return C. So, if the public procedure exists, how to I call it? I know that this is really simple stuff, but I need examples to be simple.

Inside my application I created the following class
Code:
Public Class clsProject
Public Sub AddData(ByVal cproject As string)
...
end Sub
end Class
I want to call this procedure from a sub in a form. So in the code behind file I wrote
Code:
Imports TextMgmt.clsProject
Public Class WebForm1
Inherits System.Web.UI.Page
Protected Sub btnAddData_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnAddData.Click
Call clsProject.AddData(txtInput.text)
End Sub
End Class
I get the following design time error: Reference to a non-shared member requires an object reference.I thought making things Public would make them visible.

I have been working a in a function to send all the properties of a class to a store procedure in any DB. I made it work when i define the specific class in the declaration of the function like this:
protected Boolean LoadDataDB(Class1 objClass1,Type t,String StoreProc)
But what i want is to make this function as generic as posible. I thought on replace the "Class1 objClass1" part with something like "object obj" but it didn't work. If Ipull this of, it will be very usefull for me. Up next i'm copying what i have so far.

The error appears in the wrap.AddInParameter line, in the following code:
objeto[Prop.Name.ToString()]
And it says something like "Can not apply indexing with [] to an expression of type object"

When I try to create a stored proc in SQL Server Express 2008 by right clicking on the Stored Procedures folder of my database and selecting New Stored Procedure, then attempt to save, it saves the procedure as a SQL query in the projects folder instead of saving it as a stored procedure in the Stored Procedures folder of my database.

Using vs.net 2005 and sql server 2005.
Hope this makes sense: I need to create a stored procedure that I am going to use as a datasource for a crystal report in vs.net.
The issue is that the data is stored in 2 different kinds of databases, one is sql server and the other is plb files.
I have an odbc connections created for each separately however I need to make one query that joins data fields from both the sql server db tables and the plb db, how do I do this in one query that I will use in a stored procedure?
