VS 2010 Program Hangs On Client Computers?
May 5, 2011I've created a multithreaded application that copies data from one directory to another, and I'm having trouble getting it to work properly on clients' computers. All computers running the software have Windows 7 and the .NET Framework 4.0 Client Profile installed, which is what I've compiled the program for. I have two threads: one does the actual copying, and the other updates the UI on the program. Whenever I run the program on my computer, even if I'm copying 45 GB, for example, it runs fine. However, if I run it on another computer, it will sometimes freeze the entire computer, so then I have to manually shut the computer down in order to use it again. I have been trying to find out why this occurs, but I cannot. Does anyone think he/she can provide me with some ideas as to why this happens and how I can prevent it from occurring?

View 3 RepliesVS 2010 - Keeping Files / Folders Synchronized Across Multiple Client Computers
Aug 10, 2011(Currently using VB.NET 2010 Express) I'm trying to make a program, the main of which is file transfer. I'm trying to create a program that will keep files and folders synchronized across multiple client computers. I'm using a File system watcher to trigger events, and Using a simple System.Net.Sockets UDP client transfer (found via google) to transfer commands between it and itself on other computers.
Here's that code (this just sends from one textbox to another over the internet)
Imports System.Net.Sockets
Imports System.Net
Imports System.Text
Dim udpClient As New UdpClient(1024)
Dim RemoteIpEndPoint As New IPEndPoint(IPAddress.Any, 0)
[Code] .....
By this method, I can rename, move, or delete files. I want to implement file transfer, so that whenever a new file is created, or updated, my program will automatically transfer the file to the other computers and update them there.

Access Database Path On A Networking Computers
Apr 18, 2012Am working a vb.net 2008 project using ms access database 2007 and i successfuly finished it. i published the project and burnt it with cd. my database path in vb.net was located c:Deploydatabase.accdb.
so i installed the program in to another 2 networking PCs. when i run them and put the database path c:Deploydatabase.accdb in every computer, its working. but the problem is that:
i need the database to be accessed by server or my machine for instance where every other networking computers are able to access my database in this location of my machine (my be as defualt) without not putting it to their pcs.
This enables me to see what every machines users can add information to the program.
for example, i have got 10 computers networked each other (i.e comp1, comp2, comp3, comp4, comp5, comp6, comp7, comp8, comp9, comp10). i have installed the program in every computers so when/if comp1 adds/edits informations to the program, then all other computers are capable of receiving this information which means comp4 can see what comp1 has entered in the program.

Client/server - Can't Access Communication Variable?
Aug 14, 2011I have a client/server program. There is a variable called readData that takes returndata and places it there. My question is, why can't I access this variable directly, for instance, varC = readData and then try to access a piece of it i.e. textbox1.text = varC(2), I get an error "object reference not set to instance of an object". Why is this happening? It is because the readData is a networking 'component'? How do I get around this? I can post more code from the server app if needed.

VS 2008 Client Server To Access A Database?
Dec 10, 2011I would like to create a server program that accesses an "ms access" database. I will also need a client program that connects to the server. The reason for this is that the server is a mediator for several clients. Since I am using access, I plan on maybe having 20 or 30 clients connect to the server only. The client will have access to a virtual market. So when a person buys or sells something on the market, the server mediates the transaction and etc. At the same time, the access database saves each clients data as well as the overall market data.
View 1 RepliesNetwork Program With Access Works On PC But Not On Thin Client?
Dec 17, 2010I've made a simple knowledgebase program which contains example documents. The documents are stored in a folder, and in an accessdatabase stands the information about the documents.The program also includes a simple search option. The program itself is located in a folder on a network computer.It has to be a network program for collegues can add other examples.Now it gets weird. at least in my opinion.When I run the program locally -> no problem.When I run the program from another network PC -> no problem.But when I run the program from a network Thin Client -> shaboom..At least when I enter a search option and the connection to the database is opened:"Application attempted to perform an operation not allowed by the security pollcy. To grand this application the required permission, contact you system administrator or use the Microsoft .NET framework configuration tool."[code]Now I've found a LOT of topics in this forum and many others, and it's clear that apps from another network location are run without "full trust". And the trust issue can be handled with caspol or web.config. Although caspol is a mystery to me and web.config didn't seem to work.But since it's so explicitly crashing on Thin Clients.
View 6 RepliesAsp.net - Get A Windows Form Client To Update Everytime A Access Table On Webserver Changes?
Aug 25, 2009I have a form with a list that shows information from a database. I want the list the update in run time (or almost real time) every time something changes in the database. These are the three ways I can think of to accomplish this:Set up a timer on the client to check every few seconds: I know how to do this now, but it would involve making and closing a new connection to the database hundreds of times an hour, regardless of whether there was any change Build something sort of like a TCP/IP chat server, and every time a program updates the database it would also send a message to the TCP/IP server, which in turn would send a message to the client's form: I have no idea how to do this right now Create a web service that returns the date and time of when the last time the table was changed, and the client would compare that time to the last time the client updated: I could figure out how to build a web service, but I don't how to do this without making a connection to the database anyway The second option doesn't seem like it would be very reliable, and the first seems like it would consume more resources than necessary. Is there some way to tell the client every time there is a change in the database without making a connection every few seconds, or is it not that big of a deal to make that many connections to a database?

Would my messenger just send a message to all IPs on a certain port to say I'm online and then wait for a message back from the IPs that can return messages and then figure out who is online that way?
