View 17 Repliesi 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.

And that work's like a charm, however say there was swf's from 1 to 2700 or so, how would i go around making it download each of those files one at a time or all at once? I could do a loop but I'm not the best in Visual Basic 2010

Is there any way to download multiple files at the same time from a remote server? How I am doing it currently is I get a list of files from the target folder on the server then I loop through that list & download each file 1 at a time. For 100 small files it takes about 45 seconds. I'm guessing that the bulk of the time it takes is logging in to the server for each file to download, so 100 files means it has to login, download & logoff 100 times. Is it possible to login just once, download the 100 files then logout?

View 1 RepliesI am having trouble openning my vb.net projects in vs2005. What happens when i open one is that i get several windows downloading files from the Appdatalocal emp folder. It says "do you want to open or save this file?. the file name is several random charactors with the tmp extension. do not suggest a virus. The tmp files in question are vs 2005 generated files. they contain html data indicating a problem on the form. If i close all the forms in the tabbed code area, and rebuild the project, then all is well. If i don't build the project, then when i open a form up onto the code area, i get a new download message. Anyone ever heard of this? I suspect IE8 but cannot recall if this all started when i installed IE8 or not.

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.

I have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one
