I'm using an xsd file for a couple of my data sets that I'm using to read access databases. While this is great, I just got a new requirement that allows the user to change the link to the access database on their computer. Is there any way to allow them to set the path while still being able to use the xsd files, instead of doing it all through code?

I have been creating a program that copies and moves files from folder to folder; I am using this sort of code;
fileToCopy.CopyTo("path here...")
or
FileToMove.MoveTo("path here...")
My problem is, when I am copying or moving a large file, It's taking so much time and my program is hanging until all the files are completely moved or copied. How about, using a progressbar instead, so that the user will be able to see the progress of copying and moving instead of the program freezing?

I have a listbox now that displays the current contents of the clients electronic file. I am wanting to set it up so that people can drag files from anywhere onto this Listbox and move that file to the clients electronic file.
For refrence the clients folder is always situated in same place which is client filesclientID where clientID is the clients unique Id on the database.
I as seeking to move 10 file every 10 minutes from one folder to another using .NET (vb c#) I am was thinking that i could of achieve this with LINQ query, but i cant get my head around this would there be a solution with LINQ or otherwise that can select the last 10 files form or top 10 files. so that i can move only these files from Directory1 ( the big pool of files) into director 2 ( a smaller more manageable pool of files).If all fails- then i wll manually have to copy or cut to at a time.
View 1 RepliesI am making a program that takes files (inside their folders) and copies them into a selected file path. For example, I plug in my jump drive, run my program and it copies my files on the jump drive over to my PC. Now my program does this but it takes the files inside each folder in my jump drive instead of creating a folder for each one in my jump drive. The result is a mess of files in the selected pathway in my PC.I went and created variables in My.settings so that you can save the file path even after you close the program. I just want the program to copy the folders(with the files in each folder) in my jump drive and move them over to my PC.I am using this program copy the files from my jump drive over to my PC, because I save a lot of work on my jump drive and I need to back it up often.

View 4 RepliesI am having trouble opening my vb.net 2005 project from a backed up copy on a hard drive. The original files are on my old XP computer which I no longer have access to. I am trying to open the project in vb.net 2010 on Win7. I have converted the project to vb.net 2010 and when I open the file, nothing shows up, when I try to open them, it tells me the form isn't found in the project directory because it's been moved or deleted. I know that the software on the hard drive didn't back up .exe files, I'm not sure if it did back up other kinds of files. I don't want to restart the project because I've spent over a year on it and have written over 3000 lines of code on it.

View 1 RepliesI am developing an Application that uses TCP To listen for connections, and then when a message is sent to the server and then it alerts the IP that is running the server. (Lets say the server is on a iPhone, and some how the iPhone gets a text message, which alerts a tcp server running in the background via a .jar, it would send the owner of the iPhone a message on the computer telling it it has a text. This is just an example though, but I think it gets the general idea across. I've been trying to do this, and I can connect to a TCP Server (using 127.0.0.1:8888 for testing purposes, will move to a solid IP and Port later). I can start the server (its still buggy and under development) but i don't know how to connect to the server via an application, and when a certain message is received to alert the IP Running the server.
My Server Code is:
Dim serverSocket As New TcpListener(8888)
Dim clientSocket As TcpClient
Dim infiniteCounter As Integer
Dim counter As Integer
serverSocket.Start()
[Code] .....
Now I know that to connect you'd do something like
Code:
Dim clientSocket As New System.Net.Sockets.TcpClient()
Dim serverStream As NetworkStream
clientSocket.Connect("127.0.0.1", 8888)
serverStream = clientSocket.GetStream()
And I know I would have to use some sort of Byte() method to send/receive messages, but I am at a loss on how to set it all up.
I need to download a bunch of pages from a web server, ie. spidering. I know that servers are typically configured to only allow a couple of concurrent connections from a given IP, but that would already halve the total time to run the script instead of downloading one page at a time.

I have a Visual Studio 2008-SQL Server 2005 app that will be throwing alot at it. It's my testbed learning app. I'm also a student of this craft(43 years young) like another poster posted on another thread. I come from a PICK/BASIC jBase background. Anyway as-is my app has a connection to the database that is opened on form load. I close the connection on form close. It's a one form app currently. Is this wrong? It seems that maybe I should not have a connection opened possibly all day. I'm looking into incorporating Datasets, dataAdapters into my next phase of evolution. I looked at the material and it's tough. For me anyway. But I will get into it. I will fetch the data into a dataset so that I can keep the connection open only for a little while. I was turned on to this "keep the connection just as long as you need it" idea from someth

View 8 RepliesThe current project that I'm working on is mainly employing a database back-end, and I have a few questions regarding database connections in .Net, before I actually convert.
For VB6, I connect to my databases using ADODB connections and recordsets in code only, and not by binding controls. I perform my queries using SQL statements..For differentations in the type of database, such as connecting to a MySql, a MsSql, or an access database, it was mainly the connection string that had to be changed.. and ofcourse installing the drivers.
Now for VB.Net, I believe this can be done using the System.Data assembly. While looking into it, I've seen that it has a lot of members, such as System.Data.Odbc, System.Data.OleDb, System.Data.SqlClient.
My question is, what is the main difference between those namespaces (just briefly)? I would like to generally understand the main differences before I start with anything. I have also heard about LINQ. It looked very alien to me in the MSDN library. (PS: what's the deal with Ado.Net?)

I need to find a code that (when i click the "Search" Button) will start searching for all available lan and wireless connections.
All the available selections will be shown in a List Box provided.
Once i find one i want to use, i can stop the search (by pressing another button "Stop" in this case) or just straight away click the one i want and press another button ("Select" in this case) and if it needs a password or WEP then it will display or it will just connect without asking.
Im making a small servermanager for a game. I have a list of players with their IP's that are currently connected to the the whole game. I want to find out what IP's are connected to a certain process so I can match these with the list of players and then add the players that are in the server hosted by this servermanager, into the playerlist.Adding players to that list and looking them up for a matching IP already works. I just cant figure out how to find all the IP's that are connected to a certain process.
