I am trying to get the size of multiple files to make a decision according to it.
Using the code below I can get the size of maximum 2 file then a time out error pops, Iam sure it's not an error of the links or the server because when i try each link solo it works but only fails in the loop , i also tried to make a delay between each request and other but that didn't fix it [code]...
I have developed a system to update various programs. I put the programs updated into a particular folder of my site and Users can launch their update program to download and update their application.
The user interface has two progress bar, one for the single program in download and the second for the total download.
For calculating the total amount of bytes for the second progress bar I need to know the dimension in bytes of programs and files to be downloaded before start downloading. See the attached code.
For that I read, in remote mode, the size of all the files checked and I obtain the total amount of bytes.
All works fine with various type of files (.EXE - .DOC - .JPG - .TXT etc).
The problem arises with the Crystal Report file (.RPT).
The error 404 occurs but the file exists, the server WEB is active and the other files of the list are summed. If I compress the same file in .ZIP all works.[code]...
How can i get the size if a distant file (exe, zip or rar) in vb.net.Also optionaly how can i get the current download rate while downloading this file with (network.downloadfile ("urlofFile","saveto")).
View 14 RepliesI have a bit of a problem! I am in need of a way to get the size of a remote file, without download the file itself (so that i can show download status in a status bar)

Two instance of same exe where running simultaneously in same PC but error was thrown only by one instance Program uses both sqlconnection(ADO.NET) and ADODB connection(upgraded from VB6) and the error is thrown by both types of connection. If the error is due to network problem with the server then why few programs work fine? I am not able to trace the reason for this behavior of the program. Can I know why this error occurs and why only in few programs of same instance.
