Using URLdownloadtofile To Download Files In Program?
Nov 22, 2009
I am using URLdownloadtofile to download files in my program. It works perfectly in Windows 7 64 and vista 64, but on my xp 32 and on a friends win7 32 i get an error.System.AccessViolationException: Attempted to read or write protected memory. This is often an indication that other memory is corrupt. at downloadtest.Form1.URLDownloadToFile(Int64 pCaller, String& szURL, String& szFileName, Int64 dwReserved, Int64 lpfnCB)at downloadtest.Form1.DownloadFile(String sSourceUrl, String sLocalFile)
I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
So I have a button and an image. Is there a way that I can compile the image with the program, and when the person clicks the button 'Save', the save file dialog pops up and you can save that file to your computer?
i have a audio program that will play some mp3 files from a folder. but the audio files together take up about 1 gb. it is possible to let my program download the files from the internet after it is installed on a computer. to a specific folder..?
I am new to Visual Basic. I have Visual Basic 2010 Express. I am planning to make a program that can download files from a website to put on an SD Card to Soft Mod, or hack it. I want it so that the user clicks on a radio button based on what System Menu their Wii is running on. There is currently, System Menu 4.0 or less, System Menu 4.2, and System Menu 4.3.
They also have to choose a region from a List Box. The current options are:
Region U (Americas) Region K (Korean) Region J (Japanesse) Region E (European)
I also want it so that the user can choose where to download the installation files for the Wii soft Mod.
I want to have a button that when the user clicks on it, a pop up asks them where they want to download the files to appear, once they choose a location, i want it to download a file based on what they chose and i also want it so that it tells them what to do with the files and where to put them.
was wondering about making a download program cant seem to find much on ie a download manager or something like flashget could someone point me in the right direction

My last topic about finding a file is now resolved i just had to get the subdirectories and there will always be one so i know how to do that. My next question i am lost at. My program is going to download multiple files and each file gets downloaded to a certain directory.
I am very very new to VB.NET and would like to ask a simple question. I want to create a vb.net program and allow visitors to a website to download this program. However, I prefer not to have visitors download a zip folder. I would like to have a program that just gives a prompt to save in a selected folder, once the saved file is selected it prompts the person to download, and then when finished prompts the person to run the program. The reason is twofold:
1. I don't like the extra step involved with unzipping the file. and 2. I don't like the visitors having to look for the "main" file program within the new downloaded folder. So is there any way to have just one file for others to download without having it in a zip folder?
I understand you can't download compiled files because of viruses but how do you use the seperate files? I downloaded something and it only gave me a bunch of .frm and .frmx files.
i have a plain text document uploaded to my website. The text document contains links to files that need to be downloaded for my application as an update ( i have yet to figure out how to make my own installer so i am making my own updater which is MUCH simpler). Each link has its own line. I understand how to load the file into a RichTextBox with vb.net but i do not understand how to tell one button to download each file listed.[code]

I have a web folder e.g. "url..." if I open this address in IE it show me all files which this folder have.I want to download all files but I don't want to hard-code name of files.

I have a loop set up that iterates through a List of video object and downloads them one by one. The problem is, that because of varying file sizes, I need my outter loop to wait until a file is downloaded. What would be the most efficient way to do this? I am using System.Net.Webclient As of right now the downloading works somewhat, I get about 24-27 of 94 files. The download method I am using is synchronous btw.
I am using .net 1.1 and am supposed to design a component to upload and download file through FTP server. What is the best solution for this in .net 1.1? I tried to work with the "wininet.dll". But I do not have enough information on this. What is the simplest way for connecting, uploading and downloading files throught FTP server?

hey everyone, i got a code from somewhere to download files without web browser control.The downloader only downloaded 20mb of a file, which was a big problem. I fixed that error, but now i want the code to loop through a listbox and download all the URLS from it when a "download all" button is clicked. [code]
i have been assigned a project by my organization to make a portal using vb.net which would list all the files and folders kept at the server, and i need to add a functionality wherein on a single click the user should be able to download all the files present in a particular a listbox which contains various files selected for the download, iam using file.copy method for this as the files are to be copied in the intranet only but this works fine when i run it on my computer but as soon as i deploy it and in the client server architecture the files are not copied even to the server nor in the client, although no error is shown.
