I have a loop that copies a file from the internet and writes it to disk (using a WebRequest and Response with a Stream and FileStream).Once in the loop if the internet connection breaks, the loop continues but without downloading any content (even if the internet connection is back up). I cant seem to catch this exception. If i check for a valid internet connection within the loop then the speed to download the file is way too slow
In VB .NET, how can I have two copies of an executable communicate with each other over the internet? For example... similar to how and instant messenger might work.
i am developing a software called Logon screen changer xp and i get this error [URL] what is the solution the program is created in vb.net 2008 with .net framework 2.0 and it changes a registry value and replaces a file and copies a file very simple but there are security issues with xp
I got a file to copy using vb.net 2.0 from another server to a local folder:
dim source as string = "\servernameshared directoryindex.htm" dim destination as string = "D:/local folder/index.htm" system.io.file.copy(source, destination, true)
So I'm getting annoyed with this ffriend of min that keeps on asking for code off me for a VB assignemnt. Now I'd like to give him some code, but not the right code, (play a joke on him...he...he..). So thats the reason I'd like to write a infinite loop program for Internet Explorer. Would such Visual Basic program be possible?
I'm not going to write anything epic, but probably just the event handler to a button that keeps uploading internet explorer on a infinite loop after clicking. I know morally, this is wrong. I would rather be an ass than a lazy bastard.
What I'm trying to do is write a small program that copies a file from a USB to another directory so a program already installed on the computer can load this data.Usually copying files from one directory into another wouldn't be an issue.
[Code]...
If possible i would also like to change the code i have written so it just loads January2009.txt from the "root directory" of the USB rather than having to specify H: because if i put the USB in someone elses computer this could change to G: and then it wouldn't work.
I have a vb.net project that has 2 exe's that get built as well as the installer. The two exe's share a bunch of common files. I do not want to have two copies of the common files or mess around with having build events that copy things around (if possible).
My method was to create two projects in the same folder and have them point to the files they needed. This appeared to work until I tried to compile both apps at which point I get an error in a file called Application. Designer.vb. It seems that project files create this file in their folder and when I have two solutions in the same folder they conflict. So my next effort was to create the second project in it's own folder and just add the items as needed. The problem here is that VS2010 doesn't hold a link to a file in a different folder it copies the file to the new project folder. What is the vs2010 way to get this done?
I have a question about the App.Config file. My understanding is that the connection string is stored within this file. I have setup my application so that the App.Config file is not only written to c:users<username>appdatalocal but also to c:users<username>appdataoaming. I plan to encrypt the connection string, my question at this point is will it encrypt the connection string in ALL copies of the App.Config file? It looks like at this point that the App.Config file is stored in two places on the hard drive.
i am trying to make a program that downloads a text file from the internet, the program display/edits it and then it saves it, lastly it uploads it. How can i make it that it downloads a text file and displays and then uploads it.
Okay, I will be passed in an internet address that resolves to a file of some type (.xml, .zip, .mp3, whatever). From inside my VB .NET 2005 program, I need to transfer the file down to the local machine... preferably with events so I can update the screen to show download progress. I also need a way to detect if the file specified by the user actually exists, and retrieve it's file size and compute an estimated download time.
I have looked at many other examples that show how download a file from the internet however, these examples don't work because the website I want to download these files from is secure so I don't know how to do this. I am using visual basic express 2008.
Ok this is annoying me because i know this code, but the code has left my brain. I simply need get text from a .txt from the web. Basically easiest way to explain would be so you can Change a title from the web. By making label1 the text file words. So Label1 = thewebsite.filename.txt I have done this before i have just forgotten the code. I know the code is only a couple lines. like 1 or 2, which makes me feel silly i cant remember.
we have our system running but our system needs to be modified because we did something wrong...we are doing an "Internet monitoring System" in our school library where the user can only access the internet 1hr a day, and he/she cannot use the internet within that day if he couldn't buy a time on a serve...every students should only have 20hrs time usage per semester...our problem is every day their 20hrs is being reduced in 1hr.. the rule is the time per semester which is 20hrs that is given to the students was reduced 1hr only if he uses the internet..but our system is reducing their 1hr every day.
Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
I am creating an update program to go inside of another program I am designing, and I was curious as of how to download the new (updated file) from the internet. Here is the code I have so far.
Public Class Form1 Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
in my project i want to download 1 data base file on click of a button to a specific folder and in case if the file is already there replace it.
actually i want to provide a button to update database which will download the new database(MS Access file) and replace any old.secondly will it be possible that instead of replacing, it will rename the old file(MS Access file)
I am attempting to make a "Downloader" which would download a file from the internet and save it to a local drive. However some challenges come into play, I would like the downloader to show progress. I am aware of many posts on msdn that give code on how to do this but, I would like to learn the code rather than just copy and pasting it.url...
1. How much load or data size our custom encryption/decryption algorithm can handle? E.g. what's the limit of file size that normal encryption/decryption algorithm supports.
2. What's the best way to use encryption while file transfer via internet?
3. Where and when encryption and decryption has to apply while uploading and downloading content from internet(Hosting on client or server machines)?
4. What type of algorithms suites for above approaches?
5. How much time it takes to encrypt / decrypt data for 10 MB, 100 MB, 1 GB etc
Is it even possible to run an exe file in e.g. i.e. ? How to translate it to html code? The program is an agenda and has monthcalendars and datetimepickers.
what i want to do is download a file off the internet. but what i want to do is for it to make a folder in program files called for example downloaded contect here and for it to download the file there is that possible so when i push download it will add the folder and download the contents to that folder is that possible
I have a problem with the temporary internet files. I know how to locate the folder and all the rest, but I'm going to see what second c 'is in the folder with Explorer I see dozens of files, but when I go to see through code, I see only two files, index.dat and desktop.ini. I thought that the index.dat file is a kind of file that contains the files that I see through explorer, but it seems too light, and still do not know how to copy the files it contains.
I need to download files from internet without using FTP, here's my idea:To check version of the program and also download updates.So firstly, when the user enters the splash screen there is a timer which will check updates (downloadTimer) so then downloadTimer starts to download this txt file http://localhost/version.txt and then when its downloaded (and replaced the old one that was on the computer already) and then after that, read the file. If the version.txt contains version 1.0 then pass the check and splash screen closes, main form opens, else then msgbox ("Please Wait!" & vbcrlf & "Downloading updates") and then download updates with the same way from downloading version.txtOh! and also when the file is downloaded (version.txt) save it to "c:programMyApplicationversion" downloading the file without using FTP (if there isn't any other way i could use FTP).File reading could be made with an IO.FileStream thingy.So how do i do the download part?
