I just completed building an application that reads and writes to a MS Access database located on a network drive. It works great on the computer that I created it on, but when I try to run it on another computer it fails to initialize. I'm not sure if there's a setting in the database I need to change,

Now my question is how can I make my chat program work on computers that have routers with most of the ports blocked, how do traditional chat programs do it? Perhaps The chat program intercepts packets then sends it to a known port such as 80?

Im making a tic tac toe game in visual basic 2008 express edition. I used picture boxes for the squares. after a box is clicked depending on whose turn it is i use a PictureBox1.Image = System.Drawing.Image.FromFile to call the picture whether it be an X or an O. Both the X and O files are on my desktop.The Games works fine, just as I want it.Now, I want to build the application and run it on other computers. but since the picture files are coded to read from my desktop it wont work on other computers. How do i put the pictures in my resources and read from that so it will work on all computers?

The problem is that this doesn't work on different computers. If I want to mouseclick at coordinate 55,55 on my own computer, it will actually click there. However, if I mouseclick at coordinate 55,55 on my girlfriend's computer, it will click at a different position. It will be near 55,55, but it won't be the same as on my computer.What can I use to resize a window that will work on both my PC and hers?
I am working on a project and transferring the whole project back and forth. The thing is I am using a full file path in all my code ("c:/Users/..."), so when I transfer to the other computer the file paths break. Everything I am linking to is in the "bin" folder in my project's folder. How do I have file paths relative to the project folder?
View 2 RepliesI am making a exe application and i am using mysql as my database. So the thing is, when i change to a new computer, i need to change the file path for the database connection string to that computer.
like below:
Dim connectionString As String = "Data Source=----------SQLEXPRESS;Initial Catalog=Flexlink;" & "Integrated Security=SSPI;"
i need to change the data source = --------------- SQLEXPRESS to the computer name that i am using for my project.
May i ask is there any method such that the user dont have to go in to the source code to change the computer's name like those normal installer?
Just install and the application will run according like any exe file that we buy.
I am writing a program in VB.net (vs 2008) that requires that only one instance of the executable be running at a time. Naturally I went for the simple solution by selecting the "Make single instance application" checkbox in the Project properties. Unfortunately, this option does not seem to work across multiple users that are logged into a single XP machine, thereby causing the same issues for my program as if I were able to run multiple instances on one single user. Granted this is a corner case, that someone would switch users while my program is running, but I'd like to understand the limitations. So my question is whether the "Make single instance application" property is supposed to work across multiple users? or is it limited to only one-instance-per-user.
Here are the steps the recreate the issue (prereqs: computer with XP pro installed, 2 user accounts (not on a Windows Domain), and a dummy "single instance" program created using the property mentioned above):
1) Log in with user1, start up the single instance program
2) Switch to user2 (StartMenu -> LogOff -> Switch User)
3) Start up the single instance program using user2
*After step 3, the program launches without complaint even though another instance is running on user1. Is this a glitch? or by design?

View 1 RepliesMaximized Window Size - For Multiple Users (Computers/Monitors)
View 1 RepliesSay you have a form that is designed to be maximized on startup. Now, on the programmer's computer (mine), it looks good. But going from user to user, the dimensions of monitors, as well as the resolution each user has on their computer/monitor will vary.Here is the question: If you want to have an application designed to be in a maximized window, how do you ensure that it looks the same on each and every computer/monitor that will be using it. Controls, and everything else that would normally be on the form.
View 5 RepliesI would like to develop a program (in VB2008) that can send files directly from one computer to another through the internet.
I figure there would be one program on the sending end and a separate on the receiving end. A server and client perhaps?
Anyway, I need to know how to send a file on the host machine in a simple method that is least likely to be blocked by anti-viruses and such. The fewer issues that result in a failed transfer, the better.
Also, note that my goal is to molulize this code (later) so it can be reused for multiple applications such as file sharing, gaming, etc.
I have a web portal designed in ASP.NET in which we ask customers to enter the data. On the click of submit button all i have done is, just read the data and called a stored procedure which inserts that into a table. There seems to be a problem in SQL Server 2005 while inserting the data from multiple computers at the same time. We have tested in our lab with three computers, result is that we get the data inserted successfully in only one machine and on the other two machines we get error on page. I have used transactions in the stored procedure and also tried setting the isolation levels to READ_UNCOMMITTED, SERIALIZABLE and SNAPSHOT. Nothing seems to work properly.
View 4 Replies(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.
My program is ready for use on other computers however when I run either the release file I get the following error:
(Program Name) has encounted a problem and needs to close. We are sorry for the inconvenience.[code]...
I've been working on a piece of software for a few weeks now and I've got to the point where I'm publishing it and testing it on other computers, namely my colleague's. We're both working on the same network and have similar permissions for our accounts, but for some reason the application will launch on my account but not his.
We've tried using the same computer and just changing accounts, but that won't work either; he still isn't able to launch the published application.
I receive the standard "[x] has encountered a problem and needs to close. We are sorry for the inconvenience." message.
What is baffling me is that we've tried previous versions on his computer and they worked just fine. I can't think of any changes that I've made that would suddenly stop the application from running.
A few extra pieces of information: the application has a splashscreen, which displays for a few seconds before the error message crops up. In this time, the program is supposed to check if certain files and directories exist and, if not, create them. It also changes file attributes. These files exist in a directory we are both able to access and both have permissions to change. It also changes and sets some variables within the program itself, but I don't see that being an issue. It is able to catch exceptions of type IOException and InvalidOperationException (which was being thrown when a computer didn't have access to the intranet).
I have written an application. It works fine on some resolutions but most of the controls are over lapped when it is run on some other computers.Is there any way of setting the application automatically when it is run on different computers?

View 4 RepliesI have recently finished a console application and deployed it to several computers on our network for testing. As it is just an EXE a copied to the hard drives of selected computers for now. When the app is launched it writes info to an sql DB so I always know which computers it is on.
During the past few weeks I have modified this app at least 6 times (improvements, adjustments, etc)
It is a paint to keep going back to the computers to update it with the new version, and getting mixed up which version i am on - LOL I am looking for advice on how I would go about doing this automatically, for example, it would be cool if I just had to put an updated file in a repositry and clients would use this to update.
In Visual Studio, when I view the properties of my application>assembly information - I can set a file version. Is it possible to extract this info and store it in a variable? I would like to dump the in my DB. Also I could then possibly compare the file version of the launched app against an updated file in a network share folder.
