.net - Using MS Access Database As A File Format For Desktop Application Needing Open / Save Type Functionality?
Oct 29, 2010This is probably a pretty novice design question. I'm trying to work my way through a number of requirements and give the users the experience they're looking for.I've written a tool that does big calcluation-type things. It currently consists of a class library and command line tool (separate .NET projects.) We're using an Access database format as the file type because it can keep all the various tables together in one file. A few other items about the application: There are not many users. There are no concerns with scalability. There are not great concerns with updates. Desktop is desired. Not web.Using VB and .NET 3.5 SP1
I now need to develop a GUI front end that will allow typical File/Open and File/Save type operations.Users expect that they can open a file, edit it some, then either choose to save it or close it unsaved without any changes being written back to the file. Saving it would obviously save all changes affecting all tables back to the file.
Does it then make sense to use a temp file for something like a proxy then? To, when a user "opens" a file, copy the source Access file to a local temp file and then use that for the editing session? Then, if the user "saves", copy the local temp file back to the source path?
Update: [tagged with ms-access tag too] Also, I omitted the fact that users would expect typical File / Save As functionality too. I think the design I've put in question in this post is what is traditionally called the Proxy design pattern. Has anyone tried this (successfully!) with Access database files before? Words of caution or advice?

Automate Access Error - Open Up An Access Database ?

Command Line Switches - Keeping Command Window Open?
Feb 24, 2010I am using the following code to run defrag and to analyze if the C: drive requires defragmentation:
Dim analyze As Process = System.Diagnostics.Process.Start("C:WindowsSystem32defrag.exe", "C: /a /h /u /v")

My problem is that as soon as the process is complete the command window closes. I need it to stay open so that I can read the results.

View 1 RepliesUsing VB6 To Open Access 2007 (*.accdb) Database?
Apr 14, 2009A. A Visual Basic program is developed to read a text file to Access 2003 database using the Data Access Objects (DAO). The following is the DAO command:
Set db = DAO.DBEngine(0).OpenDatabase("C:TempMyAccess2003.mdb")
B. The office Access 2003 database (*.mdb) is going to be upgraded to Access 2007 database (*.accdb).
C. The Visual Basic program is revised to read the same text file to Access 2007 database using the same Data Access Objects (DAO), The following is the DAO command:
Set db = DAO.DBEngine(0).OpenDatabase("C:TempMyAccess2007.accdb")
D. The following error message occurs when the revised Visual Basic program is executed:
"Run-time error '3343': Unrecognized database format"
I had previously used VB6; I am now using VS2008; What is the best manner to now open the database using the VB code? The code works with the Access 2003 database.

View 1 RepliesIs There A Specific Save Command That Updates Access File Permanently
Jun 17, 20101.) I dragged my detail view over to the form window to create a bindingnavigator, fields, etc.When I press save on the form, the database is temporairly saved.However, if I save my visual basic project, I lose all the changes I have made to my database.Is there a specific save command that updates the access file permanently?The default command added by dragging over the dataset does not work.

DB/Reporting :: Can't Open Access Database On Mapped Drive
Dec 8, 2008I can't open an Access database on a mapped drive. However it works if I use the UNC path. how I can get this to work? See the code below for an example of what works and what doesn't...
Code:
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=\tiger-2000dvb_mt7MTrackBE.mdb" ' This works
mConnString = "provider=Microsoft.Jet.OLEDB.4.0;Data Source=T:vb_mt7MTrackBE.mdb" ' this does not work
Dim objConn As New OleDbConnection(mConnString)
[code].....
The error message I receive is...'T:vb_mt7MTrackBE.mdb' is not a valid path. Make sure that the path name is spelled correctly and that you are connected to the server on which the file resides.I've done the obvious and verified that t:vb_mt7MtrackBE.mdb is a valid path.
Open Access Database Based On User Input?
Dec 3, 2009I've been working on an application for awhile that, basically, allows the viewing and printing of a maintenance database. It allows the user to view basic information for the object and then view the maintenance history. My approach for the maintenance history is simply to have unique tables per object since a history has to be kept for each, however, I'm running into a problem in the application that allows the user to view the general information from one DB and the Maintenance history from the other DB.
Say you have Object ID BG1. I can enter the object ID into a search field, pull the data from the general DB and display the data, but I also need it to pull the information from the maintenance history and display. If maintenance history for this object is not found, then create a new table within the DB, fill the columns with the required fields and allow for the user to edit the history.

When you opened the file with something like notepad, it just showed random ascii chars. When I needed a line of data, I could specify what line to load it from.
