<Visual Studio 2008(VB.Net) + SQL server 2005>
I have an application for HR and I am trying to give feedback to users on login window wheather it is connected network and database.
I host a few servers for different games as my hobby, I tried to make an application that would make it easier to control the servers. Should be really easy for people who has spent more time with vb then I did,This would be the interface of the application, on the textbox below the buttons is where I can specify the patch to the application that starts the server.I tried using the following lines of code, but they don't seem to be working:
Public Class Form1
Private Sub GMODStart_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles GMODStart.Click
Dim GMOD As String = Me.txtGMOD.Text
System.Diagnostics.Process.Start(GMOD)
End Sub
[Code]...
I want to check the connection of server path eg[ URL] whether exists or notI tried this System.IO.Directory.Exists("http://localhost/MyProject/ ")but it always return false.So does anybody know how to check it?
View 3 RepliesFor almost a week I am reading and trying to find a solution for checking connection state using a TCP Client (using socket class) In my scenario I have a TCP Client that is connected to a server (it is not controlled by me) and i want that from time to time to check the connection state, and reconnect if necessary.I have read a lot of information on the internet but i did not find a suitable solution.Briefly, these are the methods that i have found on the internet and try to implement.But unfortunatelly, i have found some scenarios where the TCP Server is closed and the TCP Client is still saying Connected 1.Example from MSDN

I am Using Visual Basic 2010. I want to check My Connection Status. Connected or not in Remote Server Connection (SQL Server 2008 R2). How To Check Connection Status..?
View 1 RepliesI'm having a problem with some users, my vb tools always check at the splash screen a response from a server with a simple:
Dim MyResult as string = oWebclient.DownloadString("www.mydomain.com/page.php")
This actually works for most users but in some clients the firewalls I think they block this call or bypass or something like that, I found that after telling the user to turn off the firewall everything works ok, now I have some users that according to them they don't have a firewall or they already disable and still they have the problem.
You can see from the image the error message they receive, so my question is do you know any kind of free tool that I can send to the user to maybe log what program or whatever is blocking the program to connect?
I've been Searching the Net for hours now, and i can't really seem to find anything clear and straight to the point.

I want to create a client-server application, it means I just need 1 database on the server.I have a computer and a laptop.

View 4 Replies3 years ago I developed a vb.net application that connect to sql express 2005 data base.The application worked fine.e replaced our computers, so we installed the application again. (The same exe file, the same sql server and so on).Now, only when loading few forms I receive the following message: n error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified)Note that when we log in to the application, a connection is needed. The user verifying is working fine; it means that the connection is working properly.

View 10 RepliesOk I have a question about connection string in vb.net. Im using the string [Code] but here I am specifying the serverName by its name, now if I deploy my application and send it to another person to use it I see that server name is changing according to the name of the computer. Is there any way where by I can make my application to detect itself the Name of the server present in that computer and use it in connection string?
View 2 Replieshow to check the server DateTime when the application launch. i want to make sure the user PC has the same DateTime as server when the user use the application. Reason being is some user may tend to change their DateTime backward and it causes a major confusion when it update in the server database. Below is my code....Both of the code giving problem and does not compare the date time to my pc datetime... how to check the the server datetime is same with the pc server time....
Public Sub GetServerDateTime()
Dim WMIScope As Management.ManagementScope
Dim WMIConnectionOptions As New Management.ConnectionOptions
[Code].....
I found there is something related "OnceClick"[code]...
but how to use it?? Got better solution like tray icon prompt the new version available. then prompt user permission for update~
if user accept to update, it will download from server and install and restart application.
I have a little problem with application setting in VB.net 2008. I want to switch main server and backup server connection string with combobox. [Code] It did change the Application Setting connection string in the main form when combobox1 was changed. But the problem comes, when child form was called. On the child form there is DataGridView with Dataset using application connection string. Even the Backupserver was selected on the main form, child form dataset connection string doesn't change. I don't know how to pass the current connection string to child form dataset although it is set to use application setting.
View 6 RepliesI am working on a Windows Application where i need to check a file exists in particular library with user crediantials.
Note : .Net framework 1.1 (VS2003)
I made a code that starts the Disk Check on boot time it works fine on Windows Vista and Windows Xp but on windows 7 I checked the path at were windows 7 stores BootExecute and it is on the same path. Maybe the system is blocking it. Or do i have to change the code.
Here is the code:
Dim rk As Microsoft.Win32.RegistryKey
rk = My.Computer.Registry.LocalMachine.OpenSubKey("SYSTEMCurrentControlSetControlSession Manager", True)
rk.SetValue("BootExecute", "autocheck autochk /p ??" & Drive) 'Turn ON
The Drive String just gets the name of the drive for example C: or D:
I had more problems coding for a windows 7 machine then Vista.
After running the following sub (VS debugger), I try to detach the database in SSMS, but it shows the connection open still and won't let me detach.

Private Function ClientMasterDBFiles(ByVal MasterClientDBConnection As String, ByVal DBName As String) As DataTable

In some applications, like taskkill.exe you can send info to the app when it starts up. By that i mean taskkill.exe /f /im 123.exe.... how do i make my VB.NET app read that info on startup so i get it in a string like this "/f /im 123.exe". I have absolutly no idea what this is named,so thats why im asking here.
View 3 RepliesI have an application that uses many forms and a couple of modules. One module modMain contains my subMain that starts the application. In subMain an instance of frmMainMenu (insFrmMainMenu) is created with a menubar. As the user selects an item from the menu bar, an instance of a specific form is created (for example insFrmViewCustomer). That instance is opened with the ShowDialog method. When the form insFrmViewCustomer is closed, a statement in insFrmMainMenu disposes the instance of insFrmViewCustomer. modMain also contains many public functions and subs, as well as public variables. The other modules contain public functions and subs.
So, What is loaded into memory when the application starts?
And Is there a tool within Visual Studio that tells me the answer to the first question?

It works fine when server response is detected but when there is no connection or there is no server respone the program starts to crash and doesn't work, so i have to break the debuggind process.
We have a Windows Forms application that needs to run on an ASUS EEE PC on-site. The application displays some data on the Form, and processes some data in the background. It is connected via Serial Port and USB to some custom electronics at the location. We could have used a regular 8051 microcontroller for processing and displaying the data, but since we added a barcode scanner along with a database into the equation, we needed a chip with an OS, so we went with the ASUS EEE PC minimalistic machine option, with Windows XP installed, and the platform used for coding the application as VB.NET and SQL Server.
We have two user logins created on the Windows machine - an admin login, and a limited user login. What we require is that when the employees manning the on-site location switch on the computer, and login into their limited user login, instead of displaying the desktop and exposing normal Windows functionality, the machine should directly start our Forms application, and not allow the user to quit or close or minimize the application in any way, but should only display our Forms application in full-screen mode. The Forms application should have a button which, when clicked, exposes the Windows Shut-Down dialog so that the machine can be shut down when not in use.
i have a button in my application that starts a function to play sounds.But when the function starts a have a problem that my application stops working until all the sounds are played. Then a want to display a waiting screen to show the status of the current application. To this i thought to create a new thread to open the waiting window and then show the messages.
But i have a problem that when my thread finishes, it closes the waiting screen. I tryied to put a loop inside my thread, but this crashes my aplication until the loop condition is satisfied.
I know one can select Spash Screen as the application startup as per this illustration. I can't do that however because the application is called by another program which passes in parameters via Process.Start(). Depending on the passed in arguments, I need to either
Go Directly to the MainForm or Go First to a Splash Screen which will then to the the Mainform after 5 seconds.
I definitely need Step 2 above because of the slow startup time of creating an SocketConnection and the population of some Custom Controls only after the Socket connection has been established.
Would I use a startup class or module and then use that as the application startup 'form' which could be establishing the SocketConnection while also launching a Splash Screen?
This will happen at random, and I can always just catch the error and re-establish connection to the server, but I am confused as to why. When doing lots of inserting into the sql server, I only establish one connection that is public, instead of many little connections. I had my doubts on a public sql connection, but it's been running great, and I've seen no problems until this morning. Again, this random moment I hit an error that stated, sql connection state is broken. Is it bad practice to just accept this error, and when it happens, re-establish the connection?

View 10 RepliesI am trying to make an application which will list all processes in a string when it starts. After it has listed them all I enable my timer, and in the timer there gets checked if the process is in the process list (string), and if it isn't it will add it to my listbox. The only problem is, it's not working, it's never adding an item.
vb.net
Public Class Form1 Dim AllProcesses As String Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load 'The first check For Each p In System.Diagnostics.Process.GetProcesses() If AllProcesses = "" Then AllProcesses = p.ProcessName Else AllProcesses += "|" + p.ProcessName End
[code]....
I want to make that program starts when computer starts. I have no idea how to do that.
