I have made a downloader in Visual Basic 2008, using the Webclient that is built in. This is the code i have to download the file[code]...
So instead of just saving it to C: automaticlly, i want a Save dialog that the user can choose where to save the file.
I have searched for almost a hour now, but i can't find the proper code for my purposes.
Anyways, i have coded a video downloaded and i want to include a converter as a separate exe file. But obviously people may have different file directories so a simple piece of code i have used won't work. This is what i have: Also where would i place the exe file?
View 3 Replieshow I could make an application in visual basic 2008/vb2005 that detects when a new file is downloaded. One of my old time friends created the same app with visual basic 2008. It notifys you when your attempting to download a file. For e.g: I try to download "aim6.exe"
it will show a message: "C:UsersMATTST~1AppDataLocalTempsXx0Fd31.exe.part is attempting to be downloaded"
I think it uses a file system watcher.
I have an xml file that I download from a secure site every 5 minutes, I have the application set to download at 3 minutes after the hour so it runs at 3, 8, 13, and so on. The file is supposed to be there within a minute after the 5 minute increment has occured however this is not always the case, so I changed the download time from 2 minutes after the hour to 3 minutes. However I am still running into issues with it not being there even then. What I want to do is validate the downloaded xml file to ensure that the data is there and if it is not wait 10 seconds and rerun the download again.
if the file is valid it will call the SQL import Sub (),if not it needs to delete the existing file and rerun the download sub again.The problem I am having is that all the examples that I have seen when I google are for validating the xml file prior to upload or upon the xml files creation.
I am working on a website at the moment which is displaying a strange bug with generated word documents. The site has a feature on it which allows the user to download a word document containing information related to their visit. This file is generated via some vb.net code and takes an xml template of the final document and inserts the relevant content required.
The strange behaviour is that on some machines the .doc file generated displays fine and on others it displays as XML when opened in Word. Both behaviours have been seen in the same version of Office (2003) but on seperate machines. My question is really whether the error lies with the set up of word on the individual machines, or whether there is an error in the code.
The code to create the file and download it is as follows:
Response.Clear()
Response.ClearHeaders()
Response.AddHeader("content-disposition", "inline; filename=MyNewFile")
Response.ContentType = "application/msword"

I have recently programmed a site that enables a user to upload and download files to and from an FTP site.
I now wish to take it further by having an email sent out to a specific email account (Outlook 2010) confirming that a file has been uploaded or downloaded along with the file name.[code]...
i have a function which grabs images from urls, using this function:
Public Function webDownloadImage(ByVal Url As String, Optional ByVal saveFile As Boolean = False, Optional ByVal location As String = "C:") As Image

Dim bytes() As Byte = webClient.DownloadData(Url)

All the examples ive found so far point at using imagemagik or another add in.
I am trying to put something in my program so that when a button is pressed a file will be downloaded from a website. When that is done downloading add that folder to a location on the hard drive.
View 1 RepliesI have a process serves as an application updater.It checks it's local cache of files and compares this against list of files online.On it's first run there are no files in the local cache and it therefore downloads ~100 of these files.[code]This appears to work very well, since Explorer confirms that all files are extracted and available.However when I later run this process again, it cannot verify the existence of 6 of these files and therefore tries to download them despite the fact that they are clearly both present and up to date.The offending code is a simple File.Exists call which appears to deny the local existence of these files, and therefore tries to get them again.The system continues to work well, but over time the continual downloading of these 6 files is going to get kind of silly.

But it simply won't work. It always throws that exception and I don't know why. I tried debugging and it sad that the value of bundle is nothing. The error is on this line of VB For i = 0 To bundle.MessageCount - 1
The interesting thing is that it worked ONE time only. And after that time, never again. What's the problem?
I'm writing something to download about 200 small (Around 200kb) files at a time. I pass the file urls off to a class which starts the downloads. The problem is that it'll start the download (Just creates a 0kb file) and then slowly downloads each file one by one, waiting for the next to complete despite this being a threaded class. This would be fine but after about a minute, windows removes all of the 0kb files and I'm stuck with only a few of the files being downloaded. How to get multiple files to be downloaded concurrently?

Any way to save all files that are being downloaded trough the WebBrowser I've made in my Visual Studio 2010 to a specific location, by letting user to chose option save file without knowing where it saves. Or maybe to don't show the "save file" thing at all.

I am attempting to write a playlist for my media player which is already built. I have found a way to build a playlist for it but it would be helpful if I could save the contents of TextBox1 to a text file without using the save as. I am trying to get over a user inputting a file name for the finished text file so is it possible to write the file c: est.txt without using the save as dialog? I have found that I can use a vbs program file which creates a playlist in a folder. I save the vbs file text to the textbox then save it as a vbs file in the playlist directory, then execute the finished file to make the playlist.
View 5 RepliesI have researched the net, youtube, and the msdn DB, and still can not find the working answer I am looking for. I would like someone to show me how you would save the contents of "Listbox1" to a .txt file using the "Save As" Option. I know how to hardcode a savepoint in, but since there will be multiple users I would like the option to be up to the end-user.

I'm just starting out with VB and have downloaded and installed VB Express 2008. I'm researching and trying to wrap my head around programming in VB before I start working on any projects. I have a little bit of experience with ASP Classic so some of the syntax looks familiar, but I can't get a handle on database integration. Let's say I am creating an address book. Each installation is a stand-alone (no network connectivity). How are databases used in this situation? Are they built using VB Express and packaged into the installer or can you create them separately (using either Access or MySQL) and then package them into the installer? What is needed to read and write to these databases? Are there extra bits of software that need to be packaged into the installer to allow access to the databases?
What if this application does connect to a centralized database (let's say a MySQL or Access database on a web server). Is the connectivity handled the same way? Sorry for so many questions, but I just can find the answers I'm looking for when searching. I'm not necessarily looking for the actual code to do this, just an explanation of how it's possible (or even a link to some examples/tutorials).
I am trying to use Vb to call explorer to open some web pages that I already downloaded. I use this command.
Shell("C:Program FilesMozilla Firefoxfirefox.exe G:BlogsBlog35242+0")
it works fine for this file. However, I have tens of thousands files to open. So I need a variable to replace "G:BlogsBlog35242+0". Like, I write blogaddress="G:BlogsBlog35242+0" and Shell("C:Program FilesMozilla Firefoxfirefox.exe blogaddress")it doesn't work.I write, Shell("C:Program FilesMozilla Firefoxfirefox.exe" &blogaddress) it doesn't work either.

View 5 RepliesMy question is simple (the answer may not be...), What I am looking for is a way to save a file as an encrypted file (so know one can open it except in visual basic or a way to save it with a unique ending that only visual basic will recognize. I will also need to know of a way to open or load the file to.
This is going to be used in a game I am working on (and yes...I know visual basic isn't really meant for games, but it is coming together pretty well). I was originally going to have it save as a text file, but then everyone could open, read it and even change there stats. That is what this file will contain, the stats for their character, and when they load it, it will place the values into the correct spot.
I am a partial beginner or intermediate coder, I can understand code, I just don't know all there is, like saving and loading, and this is probably a little harder.
I'm trying to make an auto updater. It kind of works, but I've got some problems.I need to make the download threaded or something so you can use the program while downloading. I've tried the background worker and now the Application.DoEvents(), but I didn't get it to work.
The second problem is that the program crashes after having downloaded in a while. It may be because it isn't threaded, but I don't know.Anyways, here's my
