How to debug a complex function?

Posted By:      Posted Date: August 30, 2010    Points: 0   Category :Sql Server
Hi everybody, I got a few complex functions written by my colleague to review. These functions calculate cost of goods using one of the methods (passed as a parameter) (FIFO, RWAC, LAST cost). I've been looking at these functions or running some queries based on these functions, but I'm yet not sure I understand them fully and their logic. What is the best approach for me to test / understand these functions? Thanks in advance.Premature optimization is the root of all evil in programming.

Complex number with evaluate function



I want to read a complexnumber and evaluate the result. Like this:


Here goes:

    Dim NumType As String = "(?<Both>([-]?\d+\.?\d*|[-]?\d*\.?\d+)(?=([^i]|$))\s*\+*\-*\s*(\d+\.?\d*|\d*\.?\d+)*(?:i))|(?<Real>([-]?\d+\.?\d*|[-]?\d*\.?\d+)(?=([^i]|$)))|(?<Imag>(\-*(\d+\.?\d*|\d*\.?\d+)*(?:i)))"

    Dim rePower As New Regex(NumType & "\s*(\^)\s*" & NumType)

  If rePower.IsMatch(input) Then
      TextBox2.Text &= rePower.Replace(input, AddressOf DoPower)
    End If

The problem is related to the rePower logic in the DoPower function:

 Function DoPower(ByVal m As Match) As 

MVC too complex?


I believe lot of people will disagree with me on this one. But the MVC model sucks. The reason:

1.       Over complicated;

2.       Cannot handle complex UI;

3.       Hard to debugging as code scattered all over the place.

Content page control passes as argument to javascript function

connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly.


I dont have the SQL EXPRESS installed instead I have SQL Standard Edition.

 I have two SQL Server instances installed.

 1- UserLT (this is sql 2000)
2- UserLT\SQL2005 (this is SQL 2005 named instance)

But when i try to add a database to my VS website project I get the following error:

Connection to SQL Server files (*.mdf) require SQL server express 2005 to function properly. please verify the installation of the component or download from the URL: go.microsoft.com/fwlink/?linkId=4925

I went in Tools>Opetions>DataBase tools>Data Connection>Sql Server Instance Name (blank for default)

and changed the "SQLEXPRESS" to "USERLT\SQL2005".

But I still get the same error message. Any ideas how i can resolve this issue?

Public Shared function doubt????

I am using VB.net/ASP.NET and SQL Server 2000 for a web application.

For populating the dropdowns, I wrote a Public Shared function LoadDDL(), in which I pass the dataset and dropdown name to set.

I have my doubts that this function will produce unexpected results for concurrent users. And will mix the results among sessions because it is a Shared function.

I am confused here. Is it the right way to go?

Please advice. Thanks in advance.


Debug implementation of URLrewriter.net



After some googling and help from the forum, I have integrated the the URLrewrting.net in my project. There are no error when I build the project, but the URL rewriting does not work. I am able to figure ot where the problem is. Is there a way to debug this. The code is as below:

 Web.config file

<?xml version="1.0"?>
    Note: As an alternative to hand editing this file you can use the 
    web admin tool to configure settings for your application. Use
    the Website->Asp.Net Configuration option in Visual Studio.
    A full list of settings and comments can be found in 
    machine.config.comments usually located in 
		<sectionGroup name="system.web.extensions" type="System.Web.Configuration.SystemWebExtensionsSectionGroup, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35">
			<sectionGroup name="scripting" type="System.Web.Configuration.ScriptingSectionGroup, System.Web.Extensions, Version=, Culture=neutral, PublicKeyToken=31BF3856AD364E35">

How do I persist custom complex types in design-time


Let's say that I've got one custom webcontrol called MyControl.

public partial class MyControl: WebControl {
public IComplex Complex { get; set; }

The control is a very simple control but it holds an instance of a complex type that is accessable through a property. The property has the propertytype IComplex

public interface IComplex {
string Name { get; set; }
List<IComplex> Children {get;}

Let's say that I am able to pick one of several different types of object that derives from IComplex in design-time and assign it to the controls property "Complex" property.

Naturally I would like to persist this information to the HTML-View in a user-friendly way.

Because we don't know what type the user has picked there is no way to instansiate the type if we don't persist the name of that type. The Type could also contain more properties than the Interface the controls property is refering.

<cc1:MyControl id="MyControl1" runat="server">
<Complex> <!-

Debugging Tool: Build a Logging and Event Viewing Library to Help Debug Your .NET Framework-based Ap


Building a basic, reusable application framework can make development quicker and easier. This allows you to focus more on the problems at hand and less on the repetitive tasks involved in building any application. In this article, the author presents a framework that provides facilities to access the registry and an extensible framework for logging messages to a console window or the Event Viewer. This reusable framework can be included as a library in your projects, allowing you to display an enhanced, color-coded message log and dynamically change logging levels.

Debug: Detect and Plug GDI Leaks in Your Code with Two Powerful Tools for Windows XP


In a previous article, the author devised a simple method to detect Graphical Device Interface (GDI) objects that are not properly released by Win32-based applications on Windows 9x platforms. Because some newer versions of Windows require a slightly different approach to GDI leaks, the author has updated his techniques for those operating systems. He builds and explains two tools designed to detect and eradicate GDI leaks in applications running on Windows XP, Windows 2000, and Windows NT.
