Allow Downloadfile Only To Some User?
Oct 22, 2010
I am using Visual Basic 2010. I use successfully webclient downloadfile to download a file from a remote website. Now I want "protect" downloading so one have to "login" before to download the file. (i.e. I should like it is not possibile to simply type [URL] to download the file and so the downloading is possible only by my VB app.) I "protect" the website by a login page. I try to use webclient.credential(username,password) but the system message is error HTTP 404 (page not found).

recently discovered the My.Computer.Network.DownloadFile method and would love to use it to download files from a website (https://www...). I can include a username and password in the DownloadFile parameter list,but will it send the password in plain text? If so, is there a way to send an encrypted password?
There seem to be many ways to download files. What are the advantages or typical uses of each?

I have tried using the My.Computer.Network.DownloadFile method but unfortunately it is slow.
Executing the simple command below takes ~5-10 secs, which I would say is a lot longer than expected for downloading a 9 kb file.`My.Computer.Network.DownloadFile("http://www.google.dk", "j: emp est.html")

I'm a beginner to Visual Basic, and I made a simple program, however I want to put a 'check update' button in it... It consists of downloading a txt file that contains three numbers, if it match with the version of the program it says 'you already have the most up-to-date version' or else it asks you to download the update and then bring you to the dev blog of the program I made, however, when I download that file, it brings me a blank txt file instead of the one I uploaded into the site. By the way, I'm downloading it through HTTP.

I'm trying to download a file from the internet by clicking a button in MS Access.
I'm trying to use My.Computer.Network.DownloadFile as described here: [URL]
Private Sub Command2_Click()
My.Computer.Network.DownloadFile("http://www.example.com/temp/xml_test.xml", "C:xml_test.xml")
End Sub
but the 'Microsoft Visual Basic for Applications' IDE that I'm typing this into seems to have no idea what I'm talking about (text just turns red).
Can I just not do this through the built in VB editor or can I simply load a library or something to make it work?
Sorry but I'm very new to VB and to Access so search results are not specific enough for me to understand - lord knows I've tried.
I'm using Access 2010 but the DB was created in an previous version - not sure if that matters.

I am trying to write a program to download an image at certain time intervals from a website based on a start time, end time and the time interval. I am trying to use 3 timers to accomplish this. I want to be able to kick the program off and leave it running until I stop it. My code seems to work fine if I set the time interval for something like 2 minutes, etc. and sit and watch it, but if I set it for an hour and leave it alone, it gives me almost sporadic results.
I set it to start at 10 pm last night and end at 5 am this morning with an interval of 1 hour. It downloaded an image at 10 pm, 11 pm, 12 am, 1 am, 2 am, and 3 am and then there were no images for 4 and 5 am. I have tried this multiple times with different time spans, and seem to get sporadic results. Any insight would be greatly appreciated. Here is my current code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If TextBox1.Text.Length = 0 Or cmbStartTime.Text.Length = 0 Or cmbEndTime.Text.Length = 0 Or TextBox2.Text.Length = 0 Then
MsgBox("You must select an image destination, start time and time increment.")
Else

I'm automating downloads. I was getting this error quite a bit using Webbrowser to navigate to a PDF (various PDFs at various websites). In other words the PDF was already on display in the browser when I called WebClient.DownloadToFile. I got a LOT better results when I desisted from WebClient and switched to this API (just pass in the two strings along with zeroes for the other parameters).
[Code]...
And yet Webclient seems oriented for only two entries (username and password). How do you set up the credentials for three entries? I hate to abandon WebClient, but at this point I just don't know how to make it work.

The below code for some reason isn't working with filefront. I'm grabbing the URL that returns the file to download but the wc.downloadfile() code doesn't download the file. It creates an empty file called 100.rar in my temp directory on C: but doesn't have any data. Is there something I'm doing wrong or is filefronts redirect messing something up? If I put the URL I get with the fixUrl variable, it pops up the file to download in my internet browser fine.

I'm downloading a file from my website using WebClient.DownloadFile(),I'm wanting to do it asynchronously, so my UI stays responsive, that would require me creating an array of web clients, is that bad practice? Or is it acceptable?I have looked into FileWebRequest, but thought WebClient looked easier to implement.

I have read about Network.Downloadfile and I think I understand it! I want to know if there is an easy way to test a files date modified before downloading it. I have a lot of files in the folder. I really want to "sync" the folder. I don't want to copy every file every time I want to only download the file if I don't have the file in the destination location or if I have an Old copy.

I need to write a process to download an html file locally in my vb.net web app. I am currently using webClient.DownloadFile :
Dim myWebClient As New System.Net.WebClient
myWebClient.DownloadFile("http://archive.ncsa.illinois.edu/primer.html", _
"C: est.html")
Is there a built-in way to do this with a "save as" window instead, so that the user can select the location they would like the file to be saved to? Or would I need to write my own?

I have a oracle database. I use the OracleDataAdapter(Oracle.DataAccess.dll) for select, update, insert, delete operations. I don't set any (table) locks on my own(I only start a transaction). I have a oracle table named "test" with the entry "test1".
Now my question: Can Person A read the entry "test1" while Person B is updating/deleting the entry at the exact same time? What happens in the worst case? An old match/empty match or can it cause any kind of exception/error(e.g. "TableLocked-Exception")?

writing user info such as user, computer name, date, and time to an acces database using a button click event. Then use a query to check if the user has accepted the aggreement. If the user has accepted the aggreement then call a vb.exe that display the aggrement. I have a login script that runs the vb.exe and uses a button click that records the user info to a csv file, but if the user has already agreed to the policies I do not want it run again.

I have been trying to solve this for 2 days now, every text book I own and google have been well and truely exhausted and I am still no closer to solving my problems.I have a login facility reading in user info from a main user file. This takes all info into a temp array and then splits usernames into a username file, passwords into a password file and a current score in a score file.
I have the login working fine and everything else in my program works as intended but touching up cosmetic aspects I want to add a Message box after login to say hello and display current score. This works great for the first name in the user file i.e - after login User1 welcome to the game. Your current score is 45 As intended.But the problem arises with any other users, my message comes out as
User2 welcome to the game. Your current score is 55 I do not understand where the random new lines are coming from. I have tried assigning the message as a variable and removing new line using
