I have an android application that is creating a JSONArray with:
List<String[]> sqlist = MySQLiteHelper.selectAll();

I am working on a database for a program. I used the .mdf file, created a table, and tried to store data in it.I did not build the program yet. I am still using it on a test drive or debug mode.I added three records to the database.I closed the program for 10 minutes and went back to writing code for it.When I opened up the program again, the database only showed that I had one record.This happened before and after I wrote other code for my program.I only started having the problem today?Is it possible that there is not enough room in the database to store all the records? The variable sizes for 3 of the fields are 400, 500,500, and 1000 and the other fields are like 50 each.All together there are 7 fields. I encountered the error after i had made one of the fields a look up field.In this field, basically I loaded categories stored in an extra files into the comboBox so users can select values without having to retype it.
Can you tell me what the error is and how I can fix it or what I am doing wrong in the program?How do I set up another table and query it to pull the values I want for the comboBox field?
I'm writing it again, i'm developing an app in which user click a picture through image and image will be stored in sdcard then I have choose the picture from image view and send that picture to the server.

I have inherited a .NET 4 VS2010 solution consisting of a WinForms app and a web service. I don't have access to a server that's running a copy of the web service but I have to run, debug, upgrade and test the project that accesses the web service as well as the web service code.Later, I also want to quickly switch between a deployed web service and the code in my local projectWhat's the best strategy for changing the projects so I can make changes to both projects, test locally, deploy the web service then test against that? If I find issues, I want to switch back to "local" mode to debug.

View 5 RepliesI have a solution in VS 2010: a WCF Service Library project ("NotifyService") and two Windows Forms projects, one for a server ("NotifyServer")and one for a client ("NotifyClient"). My goal is to have a duplex WCF service that will notify any number of connected clients when the server pushes out a notification. The clients do not need to communicate to the server except to subscribe and unsubscribe from the server's updates. However I seem to be running into problems nailing down the InstanceContext.
Here's the code for the WCF service:
<ServiceContract(
CallbackContract:=GetType(INotifyCallback),
SessionMode:=SessionMode.Required)>
[Code].....
Since I'm setting everything up through code, there are no app.config files. The problem I'm having is that my Subscribe method is never called. When debugging, I get an error after stepping through that line (not an exception) that says "Unable to automatically step into the server. The debugger failed to stop in the server process." When I go back to my server form and click the button designed to raise an event on the callback clients, it steps into the NotifyService class but the _callbacks list is empty, meaning the Subscribe method either never ran, or it never ran on that instance.
I have fought with this for almost a week. This is nearly an identical copy, at least on the service-side, to what was described here, and I've compiled that and it works.
I am hoping to get some advice on a project that I am wanting to work on. I have never done a web service/windows service or anything along the lines of what I am thinking so I would like some advice from some more experienced developers.I will be using VS2008 and VB.NET. My company currently mostly works in .NET 2.0 for our commercial application, but since this will be used mostly in house I would be able to use .NET 3.5 if suggested (am just not overly familiar with the additional features in .NET 3.5).What I would like is to have a server/service that communicates with multiple PCs. I want to create an application/web page (not familiar with web development so would probably start out as a winform app and possibly move to a web app to consume the service) that would query the web service/remoting service/whatever to retrieve information from each of the PCs (track the version of the application that is running, retrieve log files, push an update program to the PC (to be run manually)).
Not being too familiar with this type of scenario I was thinking something to the effect of:Each PC run a Windows Service that monitored the local PC. When something changes (software update installed?), tell the web service that the new version is installed.A service (web service? remoting server? other?) running on a PC that would be the interface to the windows service (not sure how the web service would talk to the Windows service without the Windows service initiating, though, unless it is also running a server) on the individual PCs. The service could request an update from the PCs (get the software version, request a file). The service would also be able to push an update program to the PCs to be run manually.
I have developed several Windows Services applications which all use SQL server. In some occasions, the customer shuts down the server and then restarts it the following morning. But then, my service is started BEFORE SQL Server starts and, of course, fails.
In which order are the services started ?

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 have a windows service written in .net framework 2.0. This service installs and runs perfectly fine on both XP and windows server 2003.We have a new 2008 box that we are migrating over to, so need to get this windows service up and running.When i try to 'start' the windows service on the 2008 machine, i get "Windows could not start the <service> service on local computer. Error 1053: The service did not respond to the start or control request in a timely fashion."I have searched everywhere looking for an answer, and all I could find was a fix attributed to .net framework 1.1 for this same error. That; however, is not applicable here, as the service was written in 2.0.

I created a windows application service that runs every 20 seconds to collect data from avaya cms and then dump it into a database. I did this using a timer. Since I had to have access to the clipboard to get the data and parse it, I had to be in STA. Unfortunately,just putting the STA before the Main() (or any other sub) did not keep the service in single thread mode. So I had to create a new thread and join it like so:
Public Class CMS
Protected Overrides Sub OnStart(ByVal args() As String)
Timer1.Enabled = True

i am looking into web services to be used for a windows forms application that i want to connect to my website and return data from my database. One thing i am concerned about is security. I have only played with web service a little bit but it seems to allow direct access to it by url and then run the service, showing the results in the browser. i guess i could set it up to accept a password in the code. i guess really if i have to pass in the query criteria to the sql from the application then showing the records in a browser should not be a problem. in my web application for the site i can keep all my web services in the app_data folder for no browser access.
i just need some advice in this area. goods, bads, other options if better. i don't have a full grasp on working this way from a client side windows application.
I have a windows service application that is meant to interact with SQL server database (INSERT, UPDATE, ETC). The windows service application is also multi-threaded.I created an "App_Data " folder to keep my database and used app.config file for connection information, etc.
After installing and starting the service, nothing happens, the database doesnt get updated, etc.
Has anyone ever written a windows service application that interacts with a database? Kindly advice me on how to overcome this problem..
i have a Windows service that is hosting a WCF service through net.tcp and this is working great. I have also created a WCF service application. I am trying to add the net.tcp service reference to the service application. Then I add it to the GAC that goes ok but if I try to RegAsm the WCF service application to allow it to be called from Server.CreateObject I get the error:
Warning: Type library exporter encountered a type that derives from a
generic class and is not marked as
[ClassInterface(ClassInterfaceType.None)]. Class interfaces cannot be
exposed for such types. Consider marking the type with
[ClassInterface(ClassInterfaceType.None)] and exposing an explicit
interface as the default interface to COM using the

It does not work. I have tried to call it through a class library but this does not work either as the end point is not set correctly.

View 3 RepliesRequest format is unrecognized for URL unexpectedly ending Error I have 3 webservices on windows 2003 server.

I've been researching for days and I've gotten to the point where my WCF service creates an Access object via com/interop.I've ran the Open Current Database call for the Access object without an error but Application.CurrentDB is still nothing/null. If the CurrentDB is nothing then I surely can't call Application.Run "myFunction" I realize WCF services aren't meant to be user interactive, but it's a long story why I'm trying to go this route. Basically I need to have a proof of concept ready sooner rather than later and the alternative (correct) route involves the complete re-writing of a large complex access VBA application. It's not a permissions issue, I have the IIS user names added to the security tab. What I really need is a way to set Environment.UserInteractive to true so my WCF service can create an instance of Access on my server machine, run the VBA functions, close out, return true.I'm using VS 2010 for the WCF, IIS 7 for my server, Access 2010 for the VBA application.
