Hi I have a Visual Basic Project Exe which runs fine on a Single Machine i Want it to be Execute for Multi User in LAN. I Have Used Crystal Reports in My Project and database is MS Acess. Please Help me how run the Project in LAN..
A VB EXE is a client architecture which usually needs installing on each client machine using it. The code in the EXE could/would normally then connect to external shared, singular resources over a network (such as databases, reporting servers etc.) but the actual EXE itself would typically be duplicated upon each client computer.
If you need all the users to open the exe and have it always run on the same machine, then you could create client shortcuts or use a script with a CreateObject("application.NameHere","serverToRunAppOn") call &/or modify the DCOM settings for the app through the dcomcnfg tool...
However I'd sugguest instead re-evaluating your architecture. Possibly turning your app into a better practice web-based or MS Access shared MDE+MDB solution for clients to connect to.

I am developing desktop app using wpf mvvm,however I am confused as to how should I proceed with developing standalone application using sqlite,sql server compact etc
If you need a database (really need a database), I suggest using Entity Framework using the code first approach. This can create a local database for the application w/o the need of a database server.
However, strongly consider if you could just use files in the file system. It is amazing how much you can load into memory and if you want this to run on client machine, you likely don't have so much data that you can't just load the data into memory.
SQL Server Compact requires a separate installation step with administrative credentials.
SQLite is a library that can be compiled directly into the application.
In the case of .NET, it is a part of the System.Data.SQLite package, so it is automatically available when your application is shipped with this package (see SQLite deployment for .net application).
I have a small VB.NET application to handles a custom URL protocol. It is set up in Visual Studio with the option to "Make single instance application". This has worked for hundreds of installations, but a recent customer is using Windows Terminal Server 2008, and it is launching multiple copies of the application. It does not seem to sense that it is already running for a specific user. BTW -
Multiple users can run it without problems in different sessions.
Is there some sort of setting on the Windows Terminal server that could cause this?
We have installed the application using install mode, and with the administrator ID.
Any ideas would be appreciated.
I have the source code of an windows service which is written in VB.NET
I came through various methods to debug this service using development environment (Visual Studio). But the challenge is, I need to deploy it in one of our servers as other application on that server need to access it. The server doesn't contain any development or debug tools. I am not allowed to install visual studio in it.
Is there any other way to debug the windows service on this server?
My intention is to understand the method call hierarchy, as this is a very complex code and I didn't write it. It has a very complex architecture and it is not possible to track the data flow only by looking at it.
If the only restriction is you can't install Visual Studio, I'd suggest you get the Remote Tools for VS 2012, which don't even need to be installed to the server, just a machine with a share accessible from the server. Then follow the instructions.
I have a windows form application that I need to publish, I just need some advice on what would be the best way to publish an application to a server so that multiple users can access it using a short cut on their desktop and without having to actually install the application on their local machines.
Thanks
You may run into CAS problems. It is better if users download code to their machines. Then you talking "ClickOnce"

I'm currently writing a program which will need to incorporate writing its output to a database rather than flat text files.
I know that if you use a Database system like SQL Compact, when you build and publish the program (or just build and distribute), your client will have to download and install SQL Compact Server.
My question is:
When using the built in Microsoft Office exports (like writing a Word File, or Writing an excel file), does the client need to have Microsoft Office installed on their machine to make use of these?
When writing to an Access Database, does the client user need to have Microsoft Access installed on their computer?
I'd appreciate any response.
Yes to Excel. You could create the Access database via ADO or ODBC, and that comes with Windows itself. You could store data from your app there, and the clients would use it through your app (or any other that can connect via ADO/ODBC).
Using the MS Office COM automation requires that the MS Office product be installed on the machine running the automation.
There are third-party code libraries that replace that functionality with their own code, meaning your app could create it's own Excel-compatible files. However, your users would still need Excel to use them.
You can also use other databases (eg., MySQL, Firebird, SQLite, and others) that are available that wouldn't necessarily cost your client anything if they installed it (or, for some, if you included it in your installation for them).
