View 2 RepliesAccess A Database Which Is Presently Saved In .cds Format?
Apr 1, 2009I'm trying to access a database which is presently saved in .cds format (which I believe is a TClientDataSet) from within my programme written in VB.Net. The reason being, is that the programme I am writing uses the same database as another programme. Both programmes will never being running at the same time, and it is a read-only operation so I could potentially duplicate the database and convert the database to an SQL-compatible format, but obviously this isn't a tidy solution.Is there anyway that I can directly read data from the .cds file with VB.Net? It seems like this would be something that is not too complex and wouldn't be too different from just reading a .csv file.

Is there another way to do this? My original intention (like stated in the original question) is gathering some (actually, a lot of) fields.

Asp.net - Insert Date/time Into Access Database
Apr 20, 2012I'm using ASP.NET/VB and I'm trying to insert a date and time into an Access date/time field, but I'm getting an error (Data type mismatch in criteria expression). Here's a simplified version of my code:
Dim myDate As Date = Now()
Dim myIns1 As New OleDbCommand("INSERT INTO tableCourse (date_submitted) VALUES (?)", myConn)
myIns1.Parameters.AddWithValue("@myDate", myDate)
myIns1.ExecuteNonQuery()
Not sure why I'm getting the error, and not quite sure if this is even the correct way to approach inserting the current date. From looking at other similar questions it appears there are a few different ways to do this, but my technical knowledge is kind of limited so I'm having a hard time figuring it out (in other words deciphering the answers that use technical terms I know nothing about).

View 8 Replies.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?

View 3 RepliesMicrosoft Access Database From VB6 - Vista - Run As Administrator - Different Date / Time Stamp?
Mar 27, 2010I have a VB6 application which has been running succesfully for years under XP, however under Vista data loss has been observed.It appears that if the app is run 'as administrator' then it connects to the correct database file, however if the app. is not run as administrator then vista creates a copy of the database (no idea where) - hence I end up with 2 versions of the database.
In fact I can delete the database file entirely and the app. still works fine because vista is using it's own copy - the problem is how do I back up this 'vista copy' when I can't find it (search doesn't find it).

My problem is when I export the DGV to excel, the date and time show up as pound symbols until i click on the cell, and it adds the current date with the time even though in the app I only put in the time. All I want is the time to show up in the Excel cells and not to have it show up as pound signs.
