i have Windows application application developed on vb.net & Access, how can i place access database/file on cloud/internet and install application on local computer like PC and laptop then connect to access database/file...
I am entirely new to this stuff so I did some search for tutorials. Everything that I found was very technical (at least on my pov) and are very hard to follow especially for beginners like me.

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 had a engineer design our .net application back in 2009, my guess is that it was coded using visual studio, and all I have is the installer application. We have been using it on our 1 or 2 local client machines very well for the past few years, but now I want to move this front end to the cloud. Instead of installing it as an application on our windows 7 machines.
It is a very simple application used in our small warehouse that keeps track of cargo/shipments etc. It uses Sql Server 2008 Express as a backend which is stored locally.
I know how to get the database in the cloud, their are many options for that, using Amazon or Azure, but how do i get the local client application to the cloud?
I dont have access to the visual studio code, i just have the runtime executable file..
I am sure there is no way to do this, and many of SO users will say i need to re-write the front end.
I have tried to contact the developer and they hav since closed down. Is their anyway i can run this in the cloud?
I welcome all options and solutions!
Thanks.
I believe you have two options for hosting this application:
If you are able to configure the database connection string, you could host the database in the cloud, and distribute the application to your end users. However, you've already stated that you know how to move the database, so I assume this isn't an option.
The only alternative is to run the entire application on a cloud server, and send the user interface to a client using terminal services. This makes it appear as if the application is running locally on the user's computer, while it is actually running on the server.
For an off-the-shelf solution to achieve this, you could consider using Microsoft's RemoteApp Azure service. I'm sure there are other similar offerings available.
I have developed an application using VB.NET and used microsoft access as the database back end.
Deployment reqiurements : The application is to be deployed on a LAN with 5_15 machines. Any user profile can be accessed from any machine. Any changes to the database entries should be reflected on all machines.
I am confused about how I should achieve this deployment. According to my research :
1.The database should be deployed on one machine . This machine will acts as the database server .
My problem(s) : I am familiar with accessing databases on local machine but how to access a remote database?. How will the connection string look like? Do I need to install ms access on all machines or only on the server machine ? Do I have to deal with concurrency issues (multiple users accessing/modifying same data simultaneously) or is it handled by the database engine?
2.The application can be deployed in 2 ways : i. Storing the executable on a shared network drive on the server.Providing shortcut on desktop of each machine. ii. Storing the executable itself on each machine.
My Problem(s) : How does approach 1 work ? (One instance of an executable running on multiple machines ? :s) In approach 2 , will the changes in database entries be reflected on all machines appropriately? In approach 2, if there are changes to the application , is there any method to update it on all machines ? ( Other than redeploying it on each machine ) Which approach is preferable? Do I need to install the .NET framework all machines? How will i set the connection string to be able to access the database in the network?
Will I have to make any other system changes ( firewall,security,permissions) ? If given a choice to install the operating system on each machine ,which version of windows is preferable for such an application environment ?
This is my first time deploying a multi-user database application on a network.I'll be very grateful for any suggestions/advice,references,etc.
I will try and answer your questions:
Yes you should deploy the database onto a central machine. (Although Access may not the best choice for this sort of thing see: Is MS Access (JET) suitable for multiuser access?)
For connection strings look at this site: http://www.connectionstrings.com/access/
For deployment of your executable you should look at clickonce. This simplifies the install and upgrade of your application significantly. A small learning curve now will reduce your administration headache later.
Is it possible to create web-application using VB.Net in Google Application space or at least importing an application already created by VB.Net to Google Application Engine in order to run it in our Google domain?
I'm afraid not - the App Engine supports Java, Python or Go. Your easiest option for running a VB.Net app on the internet is going to be leasing your own (possibly shared) server.
With Silverlight 4 we get access to COM and with SQL CE 4.0 we get Entity Framework and nice little database server. I have a need for a standalone application (executing from a external jump drive) on a Windows machine without having to install any software. The requirement is that we cannot install any software on the target machine.
My thoughts are to develop a Silverlight out of the browser application, with SQL CE binaries included (not clear on how to accomplish) and run the application from the jump drive.
Does the solution make sense?
I found some pretty good information from the following MSDN link MSDN Private vs Central deployment for SQL CE and from Erik Ejlkov blog Everything SQL Server Compact which is really good, however the solution assumes that SQL CE is installed on the local machine.
Thanks
