If I add a service-based database to my VB.NET (2010) Winforms solution, is there a way to connect to this database from SQL Server Express Management Studio on the same computer?

View 4 RepliesRecently 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?

But when i go to that site its just the vs express websites.
Im using VS2008 Pro. I also installed other files like SQLEXPRADV_x64_ENU
Am I missing something that i need to install?
I already have "SQL Server Management Studio" listed in All Programs> Microsoft SQL Server 2008

How will I know if I properly installed the required components or application?

I have an application that I created a while ago. It's a forms based application that runs on one of our servers at work. The app works well, BUT at the moment, requires someone to manually run it, which means having the admin account always logged in, but having the server locked.Although it's a forms based application, for the majority of the time I don't need to see the forms, so can I safely make this run as a service (by adding the appropriate code), and hiding the forms?Also, is there some code I can put in to test whether the instance of the program was started as a service or from a user double clicking on the icon? If so, I'd like the user initiated instance to run with the forms visible.
View 2 RepliesI already know how to call insert, update, delete & select procedures in DataSet.xsd window. And I also know how to call queries by table adapters. But I just found out that its not possible to call all functions by queries (such as insert). It works when I test the query but when I try to add it, it says "Failed to get schema for this query". So I built a few stored procedures which do many functions (such as transaction, insert, update etc...). But I am unable to use these stored procedures in VB form. I found some tutorials mentioning that it can be done by defining connections and some other stuffs with which I don't want this to be. I want to call these procedures by writing code in VB code editor window with DataSets, TableAdapters, BindingSource etc...

I've created a windows service and started a deployment project for it. I have the project installer class in the service project and I've added the "Standard output etc.." from the service project as custom actions for the Deployment Project. When I attempt to install it, I get the error "Specified service already exists", which shouldn't happen (even though the service does exist) because the installer should be removing the old service and installing the new one.
I've checked that the versions are different, and that the Product Code is also different, also RemovePreviousVersions is set to true. Can anyone tell me why it isn't uninstalling my old service when I update then install again? .S: MODS: DO NOT MARK MY POST AS ANSWERED, IT IS RUDE, YOU HAVE NO IDEA IF YOU'VE ANSWERED MY QUESTION!Sorry, it gets ignored in my signature.Mods
Myapplication design: I have a standard application with forms that connect to a service based DB via a connection string.My goal:
We have two desktop computers, I want to install the application on both computers and to store the database on just one of them in a shared folder.
What steps do I need to take to achieve this i.e prior to publishing and after?
I have a project that I have created, it something like a contact database.It is complete with its own sql server database, and controls and forms.I kinda of understand that I can include this project into another project.This is the tricky part,Can I include my contact project into another project and add more items to the database and forms in a new project?What I'm after is like using classes.My contact database would be like the base class, and the new project would be adding more features to that project.

I can create the .NET class web project and add a web service (Visual Studio 2005) but I cannot seem to figure out how to reference it. It's easy to reference in a web site (simply address it by name), but apparently in the class library project things are different because I cannot figure out the namespace or reference name.
View 2 RepliesI'm trying to open a project we did in class the other day at home.
When I try to open the project in VB, I get an error that's not terribly helpful. It basically says the project cannot be opened because its project type () is not supported by this application.
I believe that the information I need should be contained within the paren which is blank in my error message. I've looked up the error message and all the examples I've seen contain some information there.
The project was done using VS 2008 in VB in the classroom. That's exactly what I have at home. The only thing that I can think of is that something is missing from my version of VS2008 at home. The reason why I believe this is because when we needed to use SQL, it was already installed at school whereas I needed to go out and download then install it at home. So I assume my install at home is somehow incomplete. I've thought about uninstalling everything at home and re-downloading it and selecting all of the "add-ons" when I do it. This could be a total waste of time though since I don't really know what's going on.
I just thought I'd ask around before going through that.
EDIT: I downloaded VS 2008 Pro from dreamspark. Everything seems to be working.
how to add a service to this project
I have developed an application in VB.Net 2005 Express. This app was then transformed into a windows service using a template I found on this forum. I am able to install the service using InstallUtil.exe and I am very happy, BUT the powers that be me are asking for a more eligant method of installing / upgrading the service.
All of my reading suggests I need to upgrade to VS 2008 Enterprise to achieve this goal. Before I lash out and reach for my credit card, can someone confirm the minimum requirement to achieve a pretty service installation.

View 2 RepliesWe have a asp.Net vb.net 2008 project on tfs2010. The project has one main branch and for any release we create a new feature branch which is finally deployed. Post production deployment we merge back the branch back into main branch.We are now also adding a db project to manage our SQL too. Question is how to version control the differential scripts. The db project contains all create scripts which is fine if we had to deploy thep project from scratch but the project is already live. So now any new release or hotfix would normally contain alter or change script practically.
View 1 RepliesI'm working on a project that is based on modules and plug-ins. Any of these modules might alter some part of a database in various ways. One module might write or edit one table, while another module might write or edit other tables.
The modules all communicate via events raised on a common object. Therefore, when a person using module A enters a certain change that would edit data managed by module A, the module raises a Proposed Edit event such that all other modules that might be affected by the edit will have a chance to accept or reject the edit. If no module rejects the edit, then module A makes its changes and raises an Edit event, at which time all the other modules make any changes they need to make.
That's the basic pattern, but there's a problem. If I don't share a transaction during the edit, then module A can successfully edit their tables, but module B might fail to edit their table. In some cases, the failure by B should rollback the changes made by A. Therefore, it would make sense for module A to share an open transaction for all the other modules to use while making their changes, and this gets either committed or rolled back, depending on whether everyone was successful, or not.
The problem with that design is that a person could write a new module C that had a bug which caused it to fail to update correctly. That would cause it to signal that the transaction failed, such that all the other modules, which had been working up to that point, would no longer work because this new module kept canceling the transactions. In other words, the modularity of the program has now been lost. Every module depends entirely on every other module that even cares about its data.
In most cases, what would be lost if certain modules failed would be minor, whereas what would be lost if other modules failed would be catastrophic, as there would be no way to re-create the lost data with any kind of ease.As long as this explanation is, it may not be sufficient. At least it might start a discussion. Do the actions of all the modules act in the same transaction, or should they be left to succeed or fail on their own?
I'm currently starting work on my first windows service and I've encountered what I find to be a strange error. For some reason the compiler is telling me that a whole bunch of typical classes (such as Image, Bitmap, Graphics, etc) do not exist. For example, these simple lines of code, which work perfectly in a normal project, return a bunch of errors:
Bitmap b = new Bitmap(destWidth, destHeight); //Error 13 The type or namespace name 'Bitmap' could not be found (are you missing a using directive or an assembly reference?)
Graphics g = Graphics.FromImage((Image)b); //Error 17 The type or namespace name 'Image' could not be found (are you missing a using directive or an assembly reference?)

I've never done this before, so I'm looking for detailed, step-by-step instructions on how to "publish" this Windows Service that I've written, or make it such that I can take some kind of file (or set of files) and install my service on another machine. I'm looking for a way to do this using Visual Studio 2010. I think the processes are different than in previous versions of Visual Studio.

If not is there a way of creating the folder under the bin directory and accessing it. I can manually create a folder under the bin but didnt really want to do that.
View 1 Replieshow to write the code for my project.I am to base my new project on an existing one(existing one has code that works 100%)and create an Array of a structure that bascially holds the information from a summary form AND the totals from an AddToOrder_Click event. If you are still with me)... I cant figure out what the code is for my structure and Array so that I STILL have a Summary Form but I have an array that shows when I click my PrintPreview. So an Array is basically a "space" that holds information, like my summary form except it doesnt show until I click PrintPreview right?
If I just wanted to show the table then my code belongs in the PrintDocument1_PrintPage to show the array but the actual structure code belongs in the Click_Event of my AddToOrder? Please Please understand I AM NOT asking for anyone to write my code, basically I am asking for some clarification on what exactly creating an array from a structure is and therefore determing where the structure is to be placed in my code..

View 1 RepliesI am currently working on a multi branch desktop based project using VB.NET 2008. My Admin want to see the list of currently working branches and not working branches. Additionally they want to know how long a branch is not working.
To display the offline branches I first take a ListBox control named lstListBranch and then upon that control I take another ListBox control named lstListTime to display the offline time.
I want to permanently hide the scrollbar for lstListTime control and want to scroll lstListTime when lstListBranch is scrolled.
