Need to port access database app

Posted on 2014-12-17
Last Modified: 2015-01-16
  I have this simple access database app on an old 32 bit XP machine which I am looking to retire. I have a new 2012 R2 server on this network and am looking for a simple way to give users on the network read/write/delete/edit access to this data.

The data consists of a single flat table, with a unique identifier for each record and 10 other fields. I am thinking to create an sql express db and access it with an asp or script, I thought I would find a free out of the box script on the web but no luck so far.

Could someone please point me toward an easy to implement solution, thanks :)

Can't speak to the interface, but as far as the data, you can keep it as a JET DB or move it to SQL using the SQL Server Migration Assistant (SSMA).

I think what you could add if this is a simple CRUD situation or if you have some business logic that needs to be ported as well.  If the first, then I would think an example somewhere might be expanded.   If the last, then things become a little more complicated.

and not sure what the situation is, but there's no real reason you can't keep it in Access, unless your tired of it for some reason.

Copy that database file from the old machine to a shared folder on the new server.
Grant users read/write/delete/edit rights on that folder.

SQL Server seems like overkill for this problem.  Depending on what version of Access created the .mdb, you may have to convert it to a newer version.  If you don't want to buy Access for everyone, you can distribute the Access runtime engine which is a free download from Microsoft but, you will need to create an interface for the app.  The runtime doesn't allow access to design level views so you will need to create a form the user can use to view/update the data.

Its a simple CRUD situation, I don't mind whether its access, sql, or read from a text file as long as users can access it over the network. At the moment it consists of aspx files, associated files and an access db running on IIS on a windows xp machine and accessed through the browser using a http://localhost/somefolder/somefile.aspx url.

I have attempted to port it as is, created a website in IIs on the new server, kept the file structure the same and when I attempt to browse the url I get the following error (full text in the attached file)

Server Error in '/' Application.

Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine.DLL' or one of its dependencies.  is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)
  Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

 Exception Details: System.BadImageFormatException: Could not load file or assembly 'CrystalDecisions.CrystalReports.Engine.DLL' or one of its dependencies.  is not a valid Win32 application. (Exception from HRESULT: 0x800700C1)

I have installed crystal reports basic runtime for visual studio 2008 but still see this message.

Are we talking about an Access application - forms/reports/modules/queries?  Or are we talking about raw data that is stored in an .mdb and so Access is not even involved?  Where does Crystal come into the picture?

Although Jet/ACE can be used as the BE to a website, if that is what you want, then SQL Server is a better choice.

If you are going to use Access as the FE to the data, what version are you planning on using?

regarding the error you're getting, which version of CR did you install, 32 bit or 64 bit? You may want to uninstall/reinstall CR and make sure you're installing the right version.

not sure of your background, but if you're not much of a developer you may want to hire someone to bang this out for you, it seems like a pretty simple app to develop, and should be easy to do for someone with the experience. EE does have a "Hire Me" option as well.

 I would if you have all that already.   Just focus on the error, which is just with CR and sounds like it is not installed properly.

Hi Jim and everyone
  Thanks for this, I have installed the 32 bit version of crystal reports basic runtime for visual studio 2008 and am still getting the same errors.

I simply copied all these files across, there is a bin folder with several .dll's and a storedprocedures folder with one .dll do I need to register these?

I'm very shure that this copy-paste method won't work. In the days of DOS perhaps, but not today.
You'll have to run the installer to get everything fixed.

Totally agree with gustav,

  Copy and paste won't cut it for the majority of apps in today's times.  Besides the application directory, stuff can get dumped into Windows directories, then there are registry entires, etc.  There's no end to the stuff an installer might do in order to get an app in.

 Apps/components that will work with a simple copy and paste are very few and far between these days almost to the point of non-existent.

  You need the installer for CR or change the app so that it doesn't use it.
