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.
Imports System Imports System.Windows.Forms Imports System.Security.Permissions Imports System.Net
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 have several froms in my application. When application starts, a timer starts for 30 minutes. I want to show the remaining time using a popup window, message or whatever, on whichever form the user is at that time.
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
I am looking for a VB code to upload a file to FTP Server. what I mean is after the user clicks on the Upload button, I need to show the progressBar to the user showing the status of the file being uploaded and show also the time remaining. It is for a windows form.
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 need to run sql database backup tasks everytime i click on Exit button. Suppose my database name is -myauthor which contains tables,views,procedures and this is my windows forms. as soon as i click on Exit button i want my database myauthor should create a backup file or is there any other way to do with windows forms.
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.
I have a gridview in wpf and have a two radio buttons and a button in template column. How do i access the status of radio buttons in the click event of the button?
I am trying to implement an Algorithm called "Diamond-Square Algorithm" I am having trouble ending it so that it retiurns the required result. So far I have the folloiwng.
Now for a succesful insertion i want to notify the user about a successful save operation.....i.e,i want to display a message "Successful Save Operation"to the user. How to do this using the Status Strip?
Im writing a program (has been a little while) which will gather files off my computer and make a new partition the right size to store them.I would like this to be automated since it would help if I use it on friends machines.is there a way for me to create a partition from using vb.net and api's etc rather than having to downloading partition manager each time.
I've got the code to display the current browser status text in the status bar but i want it to display the name of my web browser aswell. Example: Dreamincode.net - (Name of Webbrowser)
He is my code for the displaying staus text. Private Sub webBrowser1_StatusTextChanged( _ ByVal sender As Object, ByVal e As EventArgs) _ Handles webBrowser1.StatusTextChanged
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 two datagrids, one show Item purchase and the other Usage. 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.
Private Function Qused() As Double 'Usage(QtyUsed) Dim QU As Double = 0 [Code] .....
My project uses a lot of System.Drawing.Image commands and sometimes it gives me the out of memory error. I was wondering if there's a way to check remaining memory left and to halt a process if there isn't enough? Or if there is a more practical solution?
