I am currently having an issue with getting the data from my Access database and displaying it into my visual studio app. The database and app is set up and linked correctly, I just need to know the code that allows you to search within the Access database (using a primary key) to receive the data in a different column and insert it into a string in the C# code. For example:
I have a row with id = 3 within the Access database and need to access the data of a different column within that same row. What I need to know is how to search for that id using C# code in the microsoft form and setting a string equal to that data in the database.
If you are using Windows 7, the Jet Engine does not work.

What I'd like to do is create a Form in an MS Access database using C#, so I don't have to manually re-create the Form each time a new instance of the database is created.
What I can do successfully is use ADOX to create an Access DB, create an Access Table in the database, write data to a Table, and create an Access Query in the database. I would like to create an Access Form based on that Access Query.
I am using Access 2010 & Visual Studio 2010 with the .NET 4.5 Framework.
This seems like something that would help several C#-to-Access coders, but I haven't found the question asked anywhere on the Internet (eg Google results, StackOverflow), or in MSDN documentation for ADOX. I'm coming to the conclusion not a lot of people create Access DBs with C#, and/or it's not possible to add a Form using C#.
Any search terms, code samples or other advice will be much appreciated.
Maybe someone can help me. As part of a college project I am attempting to design a number of tables within MS Visual Studio. We had previously designed these tables using Microsoft Access and one of the fields had a data type of Yes/No. In other words the data which was been saved to the particular field in the table would only contain a yes/No value.
Is there any way to replicate such a data type in Microsoft Visual studio. We are using an SQL server database and I am able to create the table but the only thing I am unable to do is to set the value type to replicate the yes/No value in Access. I would have assumed there would be an option to set values as boolean data type but this option is not present.
To clarify the version of Visual Studio is 2010 Professional and we are building the particular tables in C#.
Can anyone advise on an alternative option to Yes/No which will still return a true/false value or even a 0/1 value would do fine.
In SQL Server you can use a bit column: http://msdn.microsoft.com/en-us/ms177603
There is the data layer where the data is stored (your DB) and there you can set tinyint or bit as your datatype (assuming you are in MS SQL since you are in in VS an C#)
And there is also the presentation and application layer where in (case you are not in WPF) are in the same .cs, where you can define a radiobutton or checkBox control find in VS 2010 toolbox, to show the corresponding data.
Basically all I want is to be able to create like a self contained database in my Windows Forms application, I do not want to connect to a server or anything like that with SQL Server, I just want like a small database in the application that can handle a few transactions.
Like for instance if I create a Windows Forms application then it would have its own small database in it and when deploying it.. it will save rows there and stuff. I remember hearing about a plug in, it started with a CT or something don't recall, but it would be a plugin for Visual Studio.
Any help would be much appreciated.

You can use SQL Server Compact or SQLite (ADO.NET provider is available here). Both are embedded database engines that run in-process. You don't need to install anything, just include the appropriate DLLs with your application.
Visual Studio has no problem providing you with just such a database. Just right click your project, add new item, and select SQL Server Database. The database created will be part of your project and can be deployed as needed.
If you have a limited amount of data you can just right-click the project and Add a DataSet. Then you can define multiple tables in the .xsd and store multiple rows. in the .xml. Then you can write some simple code in the .xsd code-behind to auto load and save defaults and even pull back rows of data. I typically use this approach for storing a single record in each table. It will also work with multiple records in each table. There's a point where if you start to get a lot of data you'll probably wish you had used something like SQL Compact Edition or something similar that you bundle with your app.
you can use sqlLite,this is the website
http://www.sqlite.org/
or you can use access too
I hope I got all that in this question title. Let me explain. We are starting on small desktop app that will snowball into a big app with many forms. The database is SQL Server. It will have classic stored procs/functions performing classic CRUD functions. Given a table or stored proc in SQL Server what is the quickest way to create a form with all the hooks to maintain a table.
For e.g. lets assume I have table like this (most code below is pseudo code)
Table Employee
{
Name varchar(30)
DOB Datetime
Address varchar(100)
}
From this as source I want to create my Target which is form with 3 labels and 3 textboxes with add delete modify buttons (or OK button to add if not exists or modify if exists)
Name: TextBox
DOB: TextBox or Datetime picker
Address: Textbox
OK DELETE CLOSE
The code generation tool or technique that will be used should generate the correct db hooks (create SQL parameters, SqlCommand, execute sql.. basic try catch etc. Is there any open source tool to do this ? Some trick or templated approach via VS 2010 ? Worst case any third party tool ? thank you
Did you have a look at http://nettiers.com ?
It is basically a set of templates (not T4) that lets you generate most of the layers you want of an
application.
I like it because it is very easy to extend what is generated and to build incremental apps with it, based on the database:
first iteration : choose your first X tables, generate any layer you like (winform or asp.net, DAL, stored procedures for CRUD, entities, ...), then extend what is generated using the partial classes provided or the base classes
second iteration : add X tables to your selection, regenerate, take advantage of all your customization.
The only down side of nettiers is that you need to have a licence of codesmith to execute the templates, and it cost 100$.
There is DBEXform designer tool to create database forms reports and applications for Windows.
Applications are execute on .Net 3.5 environment.
Latist version of DBEXform could be downloaded from http://www.willmansoft.com

Try www.metadrone.com
It's a new tool, not many templates created for it yet.
But it's easy to use to create your own templates to make generated stored procedures and forms to suit your own style of coding.
I want to set filter values in the Excel file using code and then the user will be able to download it.
I tried the approach given here but it was not setting the filter.
I am working with Microsoft SharePoint 2010 custom webparts.
It is working fine in a console application, but when we add the same code in a webpart it is failing. Again this works for Ids and not for names in a console application.
Tried to find other approaches. Any sources would be great
