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]...
I am trying to get the size of multiple files to make a decision according to it.

I am trying to make a vb.net program which will perform WMI queries to check for remote computer's name and OS. I manage to do the first query of name using the code below..
[Code]...
I am getting error "Local variable 'query' is already declared in the current block. (BC30288)".I understand that I am using same name for the object variable for performing subsequent query. Is there a way in which I can dispose the variable completely and reuse it again for querying the new required WMI detail? My search in the net couldn't give me any clue as of how to clear the variable and use it again. The issue is with two variables "query" and "searcher". Is it only possible that I should give unique names to each query object variable as I might add more queries later on?
