View 24 RepliesBITS - Background Intelligent Transfer Service - Convert Each Class In The SharpBits.Base Folder
Apr 8, 2009Has any one used BITs in VB.NET? If so, do you have code samples? I was looking at SharpBits but I have a VB project that I wanted to use BITS for. Is it possible to use it with my VB.NET program? (.NET 2.0) I was tempted to try to convert each class to VB.NET in the SharpBits.Base folder but figured I'd ask in case someone has headed down this route before.
In case you run across this question. What you can do is in the Sharpbits.Base folder (that you download from codeplex) there is a DLL you can reference in the Bin directory. You can add that into your references to access it. Marking Konrad as answer since he was kind enough to post.
I managed to get sharpbits working with some quick code which I pasted below for anyone who might stumble upon this question. Like I mentioned above add the DLL to your project.
Dim b As New SharpBits.Base.BitsManager
Dim mynewjob As SharpBits.Base.BitsJob = _
b.CreateJob("jobname", SharpBits.Base.JobType.Download)
mynewjob.AddFile("\servershareigfile.zip", "c:igfile.zip")
mynewjob.Resume()
You'll need to write some logic to check for the status of the job. Once it hits "Transferred" status you can then mark it as complete. This will write the file from a .bin to the file name you listed. Something that helped me was installing the Windows Support Tools (you can get it from a Windows 2003 Cd/DVD in the sup tools folder)and using Bitsadmin.exe to view the status of the job while debugging.

How To Get A Base-10 Log
Jun 22, 2010In old QBasic I could use the LOG function to get the base-10 log of a number. So I would have something like this...
sglFormula = 150 - (LOG(intTemp + 10) * 30)
... the LOG function would give me the log base-10 of a variable (intTemp) plus 10.How do I do this in VB.NET. Do I have to create my own log function and, if so, what would it look like?

.net - RemoveHandlers On The Base Form?
Feb 8, 2010I wonder if I can remove all added event handlers in all the child forms from the one base form in the Closing method. (VB.NET; .NET 2.0)Background: In a project I analyze a memory problem. I verified with the memory profile (see related question) and find out that some forms are not collected by the GC, probably because of the EventHandler non-removed references.
In the project all the forms inherits from the BaseForm. Now I search I way to remove in the OnClosed method foreach Control all the EventHandlers to/from the ChildForms.

Anyone Used ConQAT With A Code Base
Feb 16, 2010To quote from the ConQAT - Continuous Quality Assessment Toolkit website Long-lived software systems are subject to gradual quality decay if no counter measures are taken. Continuous quality control counters this decay through an orchestrated application of constructive and analytic quality assurance techniques. The Continuous Quality Assessment Toolkit ConQAT provides the tool-support required to enact continuous quality control in practice. It supports the rapid development of quality dashboards that integrate diverse quality analysis methods and tools.However before I spend lots of time looking at it, is it usefull for a VB.NET project?
View 1 RepliesC# - Extending The Base Class?
Mar 5, 2010When you create a webpage in ASP.net, the codebase inherits System.Web.UI.Page Now when I extend the page object to check for SessionExpired for example, I create a new class and inherit from system.web.ui.page, and overwrite some functions. The problem then is that on each page, I have to replace system.web.ui.page with my custompage class. Is there a way to extend a class by adding methods or modifying its methods directly (e.g. add the sessionExpired check to System.Web.UI.Page) ?I'm using .NET 2.0

Oct 20, 2010I have classes setup similar to this:
<DataContract()> _
Public MustInherit Class SystemTaskProcessBase
Public MustOverride ReadOnly Property Name() As String
Public MustOverride ReadOnly Property Description() As String
Public MustOverride Property Result() As SystemTaskResult
[Code]...
I need to use these classes on the client system, but also need to be able to create these "tasks" through a management interface. Each class (Task) that inherits the base, could have its own properties that are unique to each class, but at the same time, share the same common base class properties. For example, the above shows a reboot task and a delete file task, the delete file task needs to know which file to delete, so has a property for that. But the reboot task does not need this property. So when the management application is creating these tasks, it shouldn't provide a text box for the file property for the reboot task. There may be more tasks created at a later date with completely different properties.
How would I go about providing the WinForms management application a way to enumerate each class into a ListView for example, and allowing the user to create these tasks and filling in the dynamic properties that each class would have? Desired functionality would be to create a task form that creates dynamic controls available for the properties as needed, depending on the public properties in each class, but at the same time have the base class properties available as well.

Could you recommend how we introduce new base class.We'd like all new code to use the new base class. But, we would like the option to have old code still inherit from old base class so we have time to switch and test old classes with new base class.

.Net OOP Superclass Base.net And Constructor Parameters?
Mar 13, 2009I have a base class that contains a fairly large number of parameters in it's New constructor. I have 7 subclasses that inherit the Super base class. My question/issue is, all of the subclasses use the same values for most of the parameters in the New constructor of the base class and these subclasses can be called one after the other. I would like to populate the common values for the superclass and then use those for each of the subclasses, but I can't come up with a good way to do this. If I could figure out how to do this, I wouldn't have to pass all of those parameters in the MyBase.New call for each subclass. I'll try to illustrate with some code .

Call A Method From The Base Class?
Jan 3, 2011REF: http:[url].....The above reference is where I got the code below.This code adds buttons to Form1. When a button is clicked a messagebox appears stating what button was clicked. I want to have the ClickHandler fill a RichTextBox on Form1 (I added a RTB to Form1). My problem is I can't do a Dim xForm As New Form1 to fill the RTB from the ButtonArray Class. I can place my file's text in a MessageBox so I know the code I added is correct. I also tried placing a Property method on Form1 and using a Accessor to fill the RTB, however it also requires Dim xForm As New Form1. How can I get my data from files to the RichTextBox on Form1 from the ClickHandler in the ButtonArray Class? See ButtonArray Class Below.
