I am writing a vb.net client application that uses a web service to connect to the remote database.So far I am able to connect to the web service and read, add new and delete data from the database. I am having a hard time updating data.
I have a datagridview control that is bound to a dataset retrieved from the remote database using the web service.When a record is edited in the datagridview control, I need the dataset that is bound to that control to be updated and then that updated dataset to be sent to the webservice to update the remote database.
My client code in the btnUpdate_Click event
dim new_ds as new dataset = datagridview1.datasource
Dim es As New testwebservice.equipmenttracker 'the web service reference
dim msg as string = es.updateequipment(new_ds)
messagebox.show(msg)
I am connecting to a web service that returns a dataset that I use as a datasource for a windows client datagridview.
Once a user has made changes to the datagridview record(s), how do I get those changes back to the connected dataset and back to the remote database.
I wrote the sql update function in the service:
Code Snippet from web service
<WebMethod()> _ Public Sub Update_equipment_repair(ByVal repair_id As Int64, ByVal date_entered As DateTime, ByVal date_sent_in As DateTime, ByVal date_returned As DateTime, ByVal damage_description As String, ByVal vendor_id As Int64, ByVal repair_description As String)
[Code]....
This displays the records perfectly and I figured out how to delete and insert records via web service.
writing updates from the datagridview back to the database.
I am writing a small windows client application that accesses data using a web service that returns datasets.When the dataset is returned, a datagridview's datasource is set to the dataset.
My question is, how do I write changes that were made in the datagridview back to the dataset and then back to the remote database.
[Code]...
Now the client snippet that connects to the service and lists the equipment
Recently working in vb 2010 express. I'm using service-based database which is based on SQL Server. This database will be deployed at the server. Is it possible that multiple vb.net programs, which are installed in remote computers or client computers in the same network, connect to this database simultaneously? Does the service-based database support multiple connections?
I'm currently working on an application written in VB.net using Visual Studio. The app retrieves and updates data from a remote database. While debugging, I updated a particular row in the database and after messing around a bit managed to crash the app. Since then, whenever I fetch that particular row, the data that was previously updated continues to be retreived - regardless of what is actually in the database.
All other rows properly reflect the data in the database and are capable of being updated through the application as they should. However with this one particular row it continues to retrieve outdated data and locks up the application when I attempt to perform an update. Does Visual Studio create some sort of local copy of the database which was perhaps corrupted?
I am trying to communicate with a Windows service on a remote machine on the network but i keep getting an exception saying the following: "System.InvalidOperationException: Cannot open Service Control Manager on computer 'machine001'. This operation might require other priviledges. ---> System.ComponentModel.Win32Exception: Access is denied.
I'm using asmx web service to lock a folder on remote computer! When I run web service on local machine everything working fine, but when I run it on remote computer nothing happen, folder on remote computer stay unlock! I supose that I need to set security permission for this web service on remote computer, but i don't know where! So, what I need to enable executing this service on remote computer?
I have a problem with service references, I add the reference and use code similar to the one below, in VS my app conects fine to the web service, also it runs fine launching the app directly. But after I created the installer and give to final users to install they can not connect to the web service.
I put together a small app I want to use on my local network for service monitoring across a few of my servers.
I'm using vb.net express 2010 with system.serviceprocess imported The problem I am having is that my code only seems to work locally, and will not retrieve the service data for any server on my network.
For example, my local machine is called "office-pc", and when running the app on it, I get all the service information.
Dim localServices As ServiceController() = ServiceController.GetServices("office-pc") For Each localservice As ServiceController In localServices ComboBox1.Items.Add(localservice.DisplayName) Next
But, if I want the service info from my web server called "casper", I use the same code, but i change the GetServices() parameter like so;
Dim localServices As ServiceController() = ServiceController.GetServices("casper") For Each localservice As ServiceController In localServices ComboBox2.Items.Add(localservice.DisplayName) Next
After a few seconds delay, nothing happens, ComboBox2 remains empty.
It was my understanding that GetServices() would get the local machines service info unless a machine name was specified, which in both cases is true.
So why isn't it working? Do I need to set something up on the network servers first?
Am trying the following to start a windows service
Try Dim myController As New ServiceController("FCR GEFU Server 1", "10.1.1.208") myController.Start() TextBox1.Text = "Service Started" Catch ex As Exception TextBox1.Text = ex.Message End Try
Am getting the following error:Cannot open Service Control Manager on computer '10.1.1.208'. This operation might require other privileges.How should I provide the log in credentials for the remote PC !?
I've got a webservice called Converter.asmx and I've just noticed that on the remote server I basically can't connect to it. The error that I get: "No connection could be made because the target machine actively refused it 127.0.0.1:49792" and the error occurs where I'm calling the web service (second line below).
Dim webservice As New localhost.Converter results.InnerHtml = webservice.ParseData(txtInput.InnerText, options)
On my localhost it works fine. How can I change the webservice so that it'll work on the remote host as well?
I am using this code to try to connect to a computer/server from my desk top. but keep getting errors The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)
Dim options As ConnectionOptions options = New ConnectionOptions()
I have to admit that I was sceptical it would work... but below is the code. I had to make a minor change to the code you suggested. Whenever I tried IPC$ it would return a 53 result code, even though I'm sure the share exists. So at the suggestion of another website I removed the share and just the computer name and this worked.
The conditions are I don't have administrator privilege I want to see the status of a service in remote machine (server)I use the following code (vb.net with framework 2.0) to see the status
Dim sqlSvc As ServiceController Svc = New ServiceController(My.Settings.serviceName, My.Settings.machineName) If sqlSvc.Status.ToString.Equals("Running") Then displayStatus("success", sqlSvc.Status.ToString) Else displayStatus("error", sqlSvc.Status.ToString) End If
When running the code, InvalidOperationException is raised and found out that I need admin right in the server.Can I lookup the status of the service without having admin right in remote machine ?
I have a Vb.Net 4.0 Windows Service.The service is setup to run in DEBUG with generate debug set to pdb-only. Configuration is set to debug.Installer project is set to DEBUG. VS IDE is set to debug.I do a clean build and clean install of the DEBUG version.
I run x64msvsmon.exe on remote machine (W2008 R2 64bit).I attach to the process via workstation (XP PRO 32bit) in VS2010 without issue.Everything is set to debug but I get the infamous message breakpoint will not currently be hit, no symbols are loaded.
I have an off-line project. User uses a laptop to input data off line into local SQL server express. Once connected to domain (on line), local data will sync with remote SQL server using sync framework. (It is done, works fine)One job left:Since another user used another program to update some tables in remote SQL server, such as CUSTOMER, SHIPINFO, my off-line program need to update these new data once connect to domain.Here is what I design in Pseudo (take CUSTOMER as example)
1) In remote SQL server, create a store procedure (sp_customer) to select all CUSTOMERS
2) In application, create a dataset (dst_customer) based on sp_customer
3) Insert all customers data which is in remote SQL server but not in local SQL server based on CUSTOMER_ID
I'm trying to use LINQ to SQL in Visual Basic 2010 Express.
It allows me to create the .dbml file, but in order to drag items from the Database Explorer window to the design surface, I first have to get my database listed in the Database Explorer!(this is a remote SQL Server database - not a local .mdf)
I already have a good, working connection string to the remote SQL Server database, but that doesn't help me when I'm trying to generate the DBML at design time.
Can anyone tell me how to get my remote SQL Server database identified in the Database Explorere window? When I try the "Add Connection", I am limited to Access, SQL Server Compact, or SQL Server Database File. If I try to enter the IP address & port of my DB Host I get a 'database file does not exist' message. Doesn't seem to want to let me point to a remote DB server...
