I have developed a movie website and I have it hosted in a private webserver.
I had also developed a windows app through which I wanna download my movies from my site.
The movies are of file size 400mb to 700mb. I tried using WebClient but it doesn't works for large file sizes.
private void btnDownload_Click(object sender, EventArgs e)

I have the following barcode image:
I'm using the following iTextSharp VB.NET script to generate a PDF document containing this barcode:
Dim pdfDocument As iTextSharp.text.Document = Nothing
Dim filename As String = HttpContext.Current.Server.MapPath("barcode.pdf")
pdfDocument = New iTextSharp.text.Document()
[Code]....
When this PDF is generated, however, the image is appearing larger than expected, and is distorted:
I can't see anywhere where I'm setting the image to be a specific size, so why would it distort like this? And how can I prevent it?
It's crucial that this image remains the size it is intended to be so that it can be read by barcode scanners.
Screen Size of my deployment screen is larger than my development screen.
If i try to set my form size larger than my development screen size, IDE doesnot accepts this.
Please let me know How can I use a form larger than my development screen Size?
when the message box appears after enter is seleted, is there a way to:
- put a title on the message box?
- make the font size larger?
- change the background color?

I have a file on an FTP and would like to stream it to Windows Media Player or some sort of media player without having to download it first. Is this possible in VB .NET?

View 3 RepliesI have a requirement to do a quick print of a form. This form has all kinds of controls and data. The problem is that the form is too wide and the left side of the form gets cut off when printing... when I use the PrintForm power pack control.I tried using bitBlt and it did the same thing. I could not see how to shrink the image to fit.
Also when getting to the Printer Dialog, the printer option to "Shrink to Fit" did not work either.How can I shrink the image? I do not know much about printing and thus printing each control is foreign to me.
My program lists all my home movies filmed with various video cameras.When I select the video from the listbox, Windows media player plays the video.However, I would like to know the dimentions of the video before it is loaded.I could,therfore, tell which camera was used to film it.Some video is 1920 by 1088 frame width/height Some is 1280 by 720 and some various other sizes Is it possible for VB 2010 to give me the dimentions ??
View 2 RepliesI have some exe files that I've uploaded into my database as I don't want them to be publicly accessible. I tried using a link button and a generic handler to serve the file using the following code:
Context.Response.Clear()
Context.Response.ContentType = "application/exe"
Context.Response.AppendHeader("Content-Disposition", "filename=program.exe")
Context.Response.BinaryWrite(binaryfile)
The problem: Google Chrome does not treat the download as any other exe, instead after downloading it reports "program.exe is not commonly downloaded and could be dangerous." with a "discard" button and the option to "keep" the download is hidden under a context menu.
serve exe files stored in the database?
Im currently working on a program that will download some files and place them inside a folder. The tricky part is that the folder they have to be puttet into is a .jar file. The jar file is always the same place, and that is in %appdata% the full location would be "C:UsersBrugerAppDataRoaming.minecraftinminecraft.jar". With "minecraft.jar" beeing the destination for the files
Ps. Im trying to create a mod installer, since some people are having a little trouble installing mods for minecraft. Minecraft can be found at [URL]
I have been trying to download the file from a virtual directory ( which is pointing to some other location) within the web-folder. I have implemented 2/3 ways on doing that, but none of the ways download the file. The asp .net page is not even showing the error, its showing a blank screen. One of the pice of code I implemented is:
<code>
filename = LinkButton2.Text
filepath2 = Server.MapPath("/folders/") & uname & "/" & filename
HttpContext.Current.Response.ContentType = "application/octet-stream"
[code].....
All im trying to do is make a program that downloads all the files i want offline and but them in a folder, but when i go to the folder and look at the downloads they are all empty,
Here is my code.
Code:
I have about 170 files on the server with the sameending Eix and EPK in the "pack".It would have to withdraw all my files to a predetermined folder "pack".
View 4 RepliesI am using the web client to download a file. Which works ok. However, now I have to download many and the number of files to download will change everyday. I am not sure how I can get the web client to know which files have been downloaded or not? I was thinking of using a for loop to download each file. But I will never know how many there are to download? The web client could download the same file twice?

I've come up with a way of downloading multiple files specified in a txt doc held on a web server. The problem is it only downloads files not folders, im using the following from the codebank to download the files currently:
Try
mCurrentFile = GetFileName(URL)
Dim WC As New WebClient
WC.DownloadFile(URL, Location)
RaiseEvent FileDownloadComplete()
Return True
Catch ex As Exception
RaiseEvent FileDownloadFailed(ex)
[Code] .....
Can I modify this to allow downloading of folders too or will I have to use a completely different method?
I'm trying to code a program that can download multiple files at once (on different threads of course). I have created a custom listview component that will allow me to add a progressbar directly to it. What my real question is, how can i take a url given by the user from an input box and create a new webclient to handle the downloadasynchronously

View 6 RepliesBasically I want to create a little program with 5 or so text fields where I enter the specific names of movies. Upon pressing a "go" button it then does a google search(with certain criteria) for all textfield entries on the website [URL} and then download the files, if possible without opening a browser.
Search criteria:
-only video formats(.avi .mov etc)
-download url contains the "_de" tag (to insure german trailers)
That way it should hopefully find the right trailer and download it. If possible have it use progress bars.
How much work do you think this is? Or is it even possible? From a logical standpoint I don't think it's too much work... I am using Microsoft Visual Studio 2008 Express Edition. My project currently is just full of test code but I will post it anyway:

I have a listbox full of links, and I want to download them. The listbox items' text contains a link to a webpage in each one. Now I want to download each page's code to a file site1.html for example. Also for each file I need to add a number site1, site2, site3 ... How do I do that ?
View 1 RepliesI just have 1 listbox which got link in there. How can I download each file using background_worker + progressbar(current file download)?
View 5 RepliesI want to download a list of files and report whether or not each file exists or contains certain qualifiers. The files are text/web documents, with maximum sizes of about 200 KB.
I am using a For loop to iterate through the links, which are placed in an array. The problem is that while my loop is going on, all of my forms become frozen and any status updates I want to show in my forms essentially do not show up because the UI is stuck.
Is there a better way to free up the UI than using DoEvents()? I recall from a previous post that the way my function is being called, it's being called from the UI thread,. Therefore I should just start a new thread so my UI thread doesn't get hung up downloading all the files? Or should I use a timer and download each file at a specific interval so that there's some downtime in between files that allows for me to change the status to tell the user that my program isn't stuck?
Edit and side question: I just realized something really...bad. Basically in my program I play around with DOM for a WebBrowser in my main form. I'm working with a lot of the elements in the document, but they don't always exist because each page takes time to load based on a user's internet connection speed. I WOULD HAVE used a While loop to check if certain elements exist or not, but in the past when I used VB6 I noticed that this causes massive program hangs...so I used a timer instead. But those hangs were the exact same type of hang I seem to be having with this downloading files business.
Now, I just moved from VB6 to .NETa few days ago. But I just read that the reason I used timers in VB6 was because VB6 didn't support multi-threading. So...for all of those instances where I should be using a While loop instead of a Timer, should I just place that While loop code in a new thread so the UI doesn't freeze up?
If so, I am greatly relieved and I can make my code 10 times less ugly. But I will also rip parts of my hair out because it took me like a 100 hours of debugging to get my really crappy timer code working.
This is my code so far:
Code:
Private Function analyzeURLs() As Integer
Dim k As Integer
'did we make it through without any errors?

I will be downloading updates for my database and client from a separate executable that will only be used for updating.In order to prevent someone from just decompiling my app through reflector and obtaining the password to the FTP server, what would be the best way to store the FTP password?
I was thinking I could create a table in my SQL database and store it there since a SQL database is way more secure than my app.
I was wondering if there was anyway to 'scan' page sources of websites and download only certain files based on their extensions, as you would by going to view -> page source in a web browser? Then, saving, perhaps, a .pdf, or a .swf file? I really don't know where to start.
View 6 RepliesI'd like to convert a VB6 application to .Net. It downloads multiple files at once and the progress is shown in a Listview. I'm using the Winsock control in a Usercontrol. Every time I start a new download a new instance of the Usercontrol is loaded. This way I can easily download 25 files at once with very low CPU usage.
I looked into the WebClient Class to download the files, but I noticed it only downloads two files at a time. Other downloads won't start unless one of the first two downloads are finished, but maybe I'm doing something wrong.
1) What's the best way to download dozens of files at once? It must be possible to resume the downloads.
2) How do I keep the downloads apart (index number?), so the Listview can be updated accordingly? I don't need help with the Listview itself.
3) Should I use the Backgroundworker or not?
I'm using a WebClient to download a bunch of small files from a website, but doing them one at a time takes a long time, approximately 20-30 minutes for all of them. Is there a way to download multiple files simultaneously, to shorten the time it takes?
