Algorithm - Automated One-click Downloading With A Status Bar And Estimated Time Remaining
Apr 2, 2011
I've been working on an application recently, and have encountered a lot of setbacks. I'm considering switching the project to C#, but that would take a lot of time. Here's what I need to accomplish, but keep running into issues.
Here's what I'm trying to do: Automated, one-click downloading, with a status bar and estimated time remaining, etc. (~20mb downloads.) Unzipping/Extraction of files. So far, I haven't been able to smoothly achieve those with VB.Net (4.0) Has anyone? Or should I just switch to C#?

I need a start date, a Total time passed until now, an average time per step, and a estimated time to finished. How can I do that? Also, I can close the application and when start up again I want to get the time counters as the last time, so How can I store that data is normal txt file (I say txt to take advantage of the ini app file which is a txt).

I am trying to creating a windows application that can automatically sign into a website and download a file. I have managed to get it to sign in and reach the file, however a windows pop up box appears asking if you want to open or save the file and then specify a location. How can I automate this part?
Basically I want to schedule this to run each morning and download the file without any manual intervention.

I want a Timer that goes down lets say it has 12 Hours so there should be a Label looking like this:12:00:00 and then every Second the Time should go down. When the Time reaches 00:00:00 it should close and if the Program gets closed it should save the time that passed and if the Application opens again it should start counting down again there where it last stopped.

I'm trying to create a version of the game Spill and Spell. I'm having problems with a click event for Labels that is supposed to exchange the .Text value stored from the previous mouse click with the current .Text value on the new Label clicked. The labels are initialized and stored in an array on the form load.
What's happening is that the values are remaining persistent to the label being clicked.
Desired Results (example):
User clicks on lblDice1 (sender), tempLetter is set to mouseLetter.CurrentLetter, mouseLetter.CurrentLetter is set to lblDice1.Text (sender.text), lblDice1.Text is set to tempLetter. (this part works)
User clicks on lblDice2 (sender), tempLetter is set to mouseLetter.CurrentLetter (s/b initial .Text value from lblDice1 above), mouseLetter.CurrentLetter is set to lblDice2.Text (sender.text), lblDice2.Text is set to tempLetter.
What's Happening:
The tempLetter and CurrentLetter values are remaining persistent to the Label being clicked on. Ie: lblDice1 click will only display the original text associated. If I click Dice1 then Dice2 and then Dice1 again, the original Dice1 text is displayed (same for Dice2).
This is a lot easier to see. All of the controls with the exception of a button ("btnStart") are defined in the code below. Click the Start button to show values in the DiceLabels grid.
The area that's the problem is Public Sub DiceLabel_Click
(this is a work in progress...)

I have created a small game where you need to add value to be able to play. This all works fine and after every game a certain value is deducted.This all works fine but the extra credit is only added after you play again.Is there a command so I can execute a calculation (of the remaining value + the game winnings) ?

I have already made an algorithm for the problem but it still got a trouble.Suppose that I have the recap of schedule (contains on gridview named GV):
TimeStart TimeEnd TotalOccuredOnThisTime
----------------------------------------------
08.00 08.50 1
08.00 09.40 43
08.00 10.50 2
What I want to get from the algorithm is, to count the time that occured on the same period, e.g. on the time of 08.00, it's occured 46 event (see the yellow colored row).This is my algorithm:
Dim ColumnLength As Integer = GV.Rows.Count
Dim TimeStart(ColumnLength - 1) As Integer
Dim TimeEnd(ColumnLength - 1) As Integer[code]......

I use following code to download a web page source code in my project:
Private Function dlwebFile(ByVal sUrl As String, ByVal sFile As String) As Boolean
Try
Dim wr As HttpWebRequest = WebRequest.Create(sUrl)
wr.Method = "POST"[code].....
The web page I am trying to download is a intranet site. I am periodically downloading the web page for archiving purpose for future reference. The web page will list the current active jobs/projects we work. We process 100's of jobs everyday. The list item will have the Project id, Project name, Project deadline, etc.The download works fine. the web page is downloaded locally. The problem is the date/time format is changed to some other format. If I view the web page in browser, the deadline of one of the project shows as "7/15 03:00".
However, the downloaded webpage shows the deadline of that project as "Wed Jul 14 16:30:00 CDT 2010". I believe it shows in CDT timezone. Also, it shows couple of other timezone too. I think the project might be created from those countries. I am in India timezone.

Just a bit of an issue that we're trying to resolve here. Assuming We're implementing a business model as one dll and a data access layer as another dll. We want them to be de-coupled so we implement an interface for the data-access layer. Great, we could now swap out the data access layer and, as long as the new data access layer fulfils the interface we're good to go, right?
Except we're not. In the business model we need to insanciate the data access layer and, because you can't instanciate an interface, you have to instanciate the actual class. We need to know the name space and the class name.We're going to end up with a line of code somewhere in our business model that looks something like this:-
Dim test as iDataLayer
test = new namespace.DataLayer
Basically, we can declare test as an iDataLayer (the interface) but to instanciate it we need to refer to the actual class (DataLayer). So we haven't really removed the coupling. If we want to swap out the data layer for a different implementation with a possibly different class name or namespace then we need to ammend the code in the business model. We're trying to avoid that.
So far the best we can come up with is to use the activate instance method instead of the New keyword (Late Binding). Because that takes a string we could hold the namespace and classname in a config file or similar, so swapping out one component wouldn't invalidate the others, you'd just need to update the config. That's just our home-spun solution though and I can't help feeling there are betters ways out there.

I have total the QtyUsed column which I place the total on the 1st row as 11, I would like it to show 8 and show the reminder on the next row and calculate the QtyonHand. Below is the code I've tried and in work but I, think I need to kind of loop to drop to the next row. I had to place the number 1 for i to get the second row, but there may be many more rows. Not sure this is clear.
