I am working on a program that will access an Access database. I am using VB.net 2003. My program in part will record the landings of commercially caught fish. I have structured the database with species names as the column heading and then the rows would be a record of each delivery. A fisherman could make around 50 deliveries in one year.
I have in excess of thirty species in this table as column headings. When I use the DataGrid object, the default is to present my database as it is created with speices names as columns headings. Is there a way to switch the rows and columns when it is being displayed in the program, so the species names become the row headings and the data are shown to the right as a column of data?

If you manually populate the DataGridView, you can put things anywhere you like.
As a side comment, are you sure you really want the species as columns? That sounds like an open invitation for problems down the line! I'd consider using some other record layout, like perhaps a species name and a record of delivery on each record. Better yet, normalize it and have a table with species name and an integer, then store the integer to indicate the species on the delivery record. That way you can add species, change their names, add other characteristics, etc.
But you know more about the application than I do, so maybe that wouldn't work.
Good luck!

Two things spring to mind initially. One, why not use a real database, SQL Express is free and far superior to Access, and two, usng the species as a column name means every time you need to add a new species you have to alter your table. Put the species in one table and the record of catches in another - probably there ought to be a further table with the fisherman details too. Get a book on database design before going any further, as using your current design is asking for trouble in the future.
In answer to your question, you can manipulate the data within your code to do what you want, but if you use SQL Express 2008 it can be done by using the PIVOT command.

I want to thank you and Walt Fair for the response. You both mentioned SQL Express and I will look into it. I do not do a lot of this sort of work, that is why I am still using vb.net 2003. I used an Access database because that it what I had handy, but I am early enough in this project that I can switch easily.
As far as the species names as column headings. I understand your point, but for good or bad, the fishery that this program is to used in is one that is managed by the Federal Governemnt and has a management plan that identifies exactly the species involved, so adding new species will not be an issue.

Hi Peter,
I believe you get SQL Express for free with Visual Studio 2005 as part of the VS 2005 installation. With 2003, you will have to download it and install it. I would suggest upgrading.

Even so, you should bear in mind that this is a bad design which, although it may not cause you problems in this instance should really not be used - better to do it right every time rather than taking shortcuts which can soon lead to general sloppiness.

Hi,
This should be very straight forward but I am missing something. I have a database in MS-Access to keep track of my Class Reunion information. The table is called "Reunion-Table". I'm trying to read this table with C# and fill a dataGrid. However, I'm receiving an OleDbException from the adapter.fill method, which is saying, Syntax error in FROM clause. Here's my code:
private void DataSetFromOleDb()
{
string strSQL =
"SELECT * FROM Reunion-Table";
try
{
using (OleDbDataAdapter adapter =
new OleDbDataAdapter(strSQL,
Properties.Settings.Default.OleDbConnectionString2))
{
DataSet ds = new DataSet();
adapter.Fill(ds, "Reunion-Table");
dataGridClassReunion.DataSource = ds.Tables["Reunion-Table"];
}
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
}
and here's my Connection string:
Provider=Microsoft.Jet.OLEDB.4.0;Data Source="H:\users\glenn\documents and settings\db1-0706.mdb"
Any help would be greatly appreciated.
Thank you,
Glenn

Hi,
The name of the table might be interpreted as two separate words. Can you try out the syntax below?
string strSQL = "SELECT * FROM [Reunion-Table]";

Intellitrace wasn't designed to be used in an end-user debugging situation. It was designed for use during development and especially during testing. Your testers can create or recreate problems problems and send you the log files so that you can see the steps that were used to get to the problem as well as what the code was thinking as the steps were being followed.

hi their, i just wanna to know the major difference between abstract class and interface...
till now i knew like Abstract class will have connection of internally related method's declaration but in interface will have collection of unrelated methods... am i correct?

It's not a "major difference", but a few subtle differences. There's an article[^] on CodeProject that highlights the differences.

HI THEIR, 
i gone throw the article .its good but they were explained only about how to implement and syntax
differences n multiple inherit but wat i expert na why we need tat? almost both does the same thing
but why we need tat apart from the given explanation ....

Take a look at this article[^] by Microsoft.
It's time for a new signature.

I don't think that both have been thought up simultaneously with a distinct idea "let's use A in circumstance one and B in circumstance two". You got a sledgehammer and a warhammer, both have similar uses but different advantages and disadvantages in different situations.

I have created a VSTO Excel addin. It's deployment is really a headache.
I want to set VSTO 2.0 RunTime in prerequisite but I am using VS 2008 and it shows VSTO 3.0 Runtime in prerequisite list. I can not select that because that will use .NET 3.0 or above. My applicaiton is .NET framework 2.0 compatible and it requires VSTO 2.0 not 3.0 as a minimum requirement.
How to set VSTO runtime 2.0 as a minimum requirement ?
I want that If any dependency is not found on client PC then either it should be download from internet(in case of .NET framework) or it should be packaged with installation (in case of VSTO 2.0)

Are all your projects set to use and compiled to the 2.0 framework?
To verify, go to the menuitem "Project", and select "Properties". There's an "Application" tab, and it should state that it's using the 2.0 framework in the textbox labeled "Target Framework".

Yes my both projects(SetSecurity & Excel Addin) in soltion are targeting to Framework 2.0
My setup project is also showing dependence "Microsoft .NET Framework" with version 2.0.50727
|
|
|
|
|
VSTO 3 isn't supported on the 2.0 framework, I hoped that the installer would drop everything that would require a newer version of the framework.
Can you uninstall VSTO3 (to make sure there's no references at all), building[^] the setup using VS2005 & VSTO2?

unfortunately it is not getting uninstall. On uninstall it crashes and shows "Send \ Don't Send". Any VSTO run-time cleanup tool available ?
