Getting Remote File Size Error
Sep 15, 2011
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]...

[Code]...
I added a msgbox to show me what the path to the server is and this is it.Click OK and it gives me the error above.So I changed the "ofd.Files.FileName to ofd.Files.SafeFileName My msgbox now shows this:Then VS throws en error saying it can't find the file in the projects debug folder so I move it there and run the program and it uploads. I noticed that in the first msgbox it has forward and backward slashes could that be my problem or is it something else?

I have an VB.NET 2005 application installed on my Windows 2003 Server.I try to access that application for other computer on my network. Read below:I get this error when running a remote VB.NET application.
System.Security.SecurityException: Request for the permission of type 'System.Security.Permissions.SecurityPermission, mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' failed.
I had the error on my computer running Windows XP. I am use to that, so I went in the FrameWork .NET 2.0 and set the security to FullTrust and the error disapeared. Now I have the same error on my computer that is running Windows Vista and when I go do the same security changes to FullTrust, it does not work. I still have the error showing.Is there some other configuration to do on a Vista machine to be able to run a remote VB.NET application ?

I have an MS Access 2003 database built that resides on a shared network path at the company I work for.The database works perfectly for users connected directly to the company network.However, when a user tries to open the database while connected remotely to the company network (they can still access the shared path), they receive the following error:The Microsoft Jet database engine stopped the process because you and another user are attempting to change the same data at the same time.At the time that they tried it, they were the only person accessing the database.They tried a local copy as well as a copy on the network shared drive.[code]

Below error is thrown in a already opened program which connects to different database
A transport-level error has occurred when sending the request to the server.
(provider: TCP Provider, error: 0 - An existing connection was forcibly closed by the remote host.)
Program details: code done using vb.net with MSSQL 2008 as back-end
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.
