Is anything equivalent to the Microsoft Access Datasheet form available for use with the Visual Basic 2010 Express Edition? (The Data Grid View control doesn't provide the functionality I need.)
View 3 RepliesI'm trying to migrate (mostly mentally at this point) from MS Access to .NET for database programming. I've found one of the first tests to be fairly painful. I'm trying to recreate MS Access's datasheet view in Visual Studio.Features I use in MS Access Datasheet View that I haven't immediately found in the DataGridView I'm assuming that a DataGridView will be used to edit records as opposed to being used as a search/list only.1) Form Level BeforeUpdate Event - Here I typically run validation code2) Textbox level BeforeUpdate Event - If I'm feeling anal I'll run validation code here.

I'm currently doing a project that includes access 2010 My question will be what driver can I use for an access 2010 *.accdb type file? For a *.mdb it works perfectly well with
ConnString ="Driver={Microsoft Access Driver (*.mdb)};Dbq=" & Application.StartupPath & "\CITSDB.mdb;Uid=Admin;Pwd=123;"
But, when I changed the mbd to accdb:
ConnString ="Driver={Microsoft Access Driver (*.accdb)};Dbq=" & Application.StartupPath & "\CITSDB.accdb;Uid=Admin;Pwd=123;"
It resulted in errors:
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'.
ERROR[IM006][Microsoft][ODBC Driver Manager]SQLSetConnetAttr failed
ERROR[HY000][Microsoft][ODBC Microsoft Access Driver]Could not find file '(unknown)'
And then it shows me that my code for
If dsLogin.Tables(0).Rows.Count = 1 Then
IndexOutOfRangeException was unhandled
Cannot find table 0
I knew it must be the driver but I don't know what accdb driver I can use for the connstring.

I have vb .net windows form application that I want to connect to Microsoft access database using "Microsoft DAO 3.6 object library". My problem is that when I go to Project tab -> Add reference -> COM tab, there should have been "Microsoft DAO 3.6 Object Library" on the list, but for some reason It's not on the list. Then I googled, and found out that the location of "DAO360.DLL" is "Program FilesCommon FilesMicrosoft SharedDAO". After clicking on Browse tab, I browsed to that location, and I guess I added reference on another way.This is the code that I used before for connecting to Access, but for some reason It doesn't work this way on this PC.

View 2 RepliesI am a student at the University of Findlay in Ohio. In our software engineering class we were given an assignment to make a database of 2 tables in Access. Simple enough. We then had to integrate that database in to VS. Again, quite simple. Along with that we are to make 4 reports that can be displayed to the user.
The problem comes here. I can not figure out how to allow the user to select say a Recruiter Number and show all the Clients who that recruiter is in charge of as well as the amount of money they owe and what they have paid already. Also I need to total those two values.

I'm currently trying to convince management of the need to port one of our applications to .NET. The application has grown to be a bit of a monster in Access (backend in SQL), with 700 linked tables, 650 forms/subforms, 130 modules and 850 queries.
I pretty much know all the major benefits of doing this, but now need to look at how this can be achieved technically, so I can put a project plan together.So, my plan was to convert the queries into stored procedures and/or views on the backend and re-write the forms in WPF or WinForms.
Now, the code is where I come unstuck. Is it possible to packaged up the code behind and modules into dlls and consume them whilst it is slowly ported to VB/C#?
What we can't be left with is half an application in VB/C# and half in Access, it must 'appear' to all be one application, even half way through the migration.EDIT: Just some more info about what we do and why we're looking at moving away from Access.We are essentially an ISV and the Access application is our main product. This application has been developed over a period of 15 years, by many, many developers on an ad hoc basis. There is no documentation for this application.
We also have problems with getting branching in SCC to work properly, so we've currently got 4 or 5 code bases for the half a dozen clients we have. On top of that, all the testing we do is completely manual, which you can imagine is very labour intensive, and only scratches the surface of what really needs to be tested.We're currently looking to expand, and have a number of sales leads that are in the final stages. I'm worried that with these new sales, we're going to be swamped with support and testing, and that this application is going to become even more entangled an buggy.
I'll also add to this the fact that we're just about to enter the spec phase of a brand new product, which is almost certainly going to be built in .NET. If we were to rewrite the Access application in .NET, then the people we use for that can go straight on to this new development. If we were to stay in Access, then we'd have to get some new Access people in, whom would have to be retrained once we start the new development.
So essentially it has come down to two choices, major refactoring work in Access to try and 'organise' the code a bit better, and those of you who have suggested culling parts are most probably right; I'm sure there are parts that are no longer used. However, I fear that if we stay in Access we still won't be able to build in effective testing and we still won't have proper SCC branching, which will lead to support continuing to be a nightmare, and any future developments on this product makings things worse. Either way there is a lot of work that we're about to embark on, which is either going to be done in Acces, or .NET.

I am taking Computing at A Level and need to create a solution for a business.I have thought of my solution which is a log of all the cars that go out on test drive for my dads motor company, i have created a database in Microsoft Access and have saved it as the usual mdb file. i have then imported this into the project and would like to use it.I have created a login form which i would like to use along side the database in the sense i would like it to check when a user enters their name and password for those two things in the database and respond accordingly. I also have created forms in which employees would enter information and then click the submit button, i need this to then place the information into a database as records under the right headings.I have tried using the program and play about a bit but i just can't understand it easily, even when i search for help i have trouble understanding what it all means.If someone could help me that would be great cheersLongy1259

The backend uses Microsoft SQL Server 2000 runtime engine with an MSDE database engine. The frontend however is built with Microsoft VB.Net and the dotnet framework. I'm not sure how this changes things when trying to extract the tables. I've found the folders where SQL-notepad looking files are contained but am not sure what my next step should be. TBH i dont know what version of Microsoft VB.Net framework is used but the system is quite old and was made in 2001. If you haven't noticed from my poor phrasing i'm a bit of a newb when it comes to programming. If there is a particular programming code i have to put in i wouldn't really know where to put it.
