How can I create the Access database and tables at run time using c#?
I have an ASP.net security database which is normally ASPNetDB.MDF however I have created the same database structure in MS Access. All works great. However, I need to add a couple of other tables but I can't find how to do that in VWD. I'm pretty sure I was able to when the first database I created was an MDF file but not in MS Access.

Really new to C# & Web developing - but have used the DAL & BLL model from a number of the turorials. Have a situation that I not sure the best way to accomplish. I have an application dealing with courses, books, etc. utilizing an Access Database. All was going well in creating an on-line catalog using Formview and tables to display the db values stored in the Course Table (Course ID the key). User is able to use dropdown list to locate the course - dropdown list showed the Course Nbr & Name, but used the Course ID to get the detail. This issue appeared when they introduced a Prerequisite field in the Course Table. This contains the Course ID of the prerequisite course, but they want to display the Course Nbr and Name in the table field. So today it show 18 (Course ID) and they want B101 Intro to Biology. Hope I have provided enough information of what the code looks like below
Here is the FORMVIEW & TABLEROW
<asp:FormView ID="FVGeeralidades" runat="server" DataKeyNames="ClaveAsignaturas"
DataSourceID="ObjectDataSource1">
<ItemTemplate>
<asp:TableRow ID="TableRow5" runat="server">
<asp:TableCell ID="TableCell11" runat="server" HorizontalAlign="Left" Text="<STRONG>1.6</STRONG> Prerrequisito"
Width="150px"></asp:TableCell>
<asp:TableCell ID="TableCell12" runat="server"></asp:TableCell>
<asp:TableCell ID="PrerrequisitoValue" runat="server" HorizontalAlign="Left">
<%# Eval("AsignaturaPrerrequisito")%>
</asp:TableCell>
Here is also the OBJECT DATA SOURCE
<asp:ObjectDataSource ID="ObjectDataSource1" runat="server" OldValuesParameterFormatString="original_{0}"
SelectMethod="GetCourseByCourseID" TypeName="CoursesBLL">
<SelectParameters>
<asp:ControlParameter ControlID="DDLCourse" Name="CourseID" PropertyName="SelectedValue"
Type="String" />
</SelectParameters>
</asp:ObjectDataSource>

I have used a microsoft tool before that was allowing me to automatically generate admin web pages from database tables. By admin web pages I mean pages that allow me to do CRUD operations on my tables.
View 1 RepliesI am working on a multi-lingual application Assume the following:
Database has 50 tables and application has to support 5 languages
Which is the best way to design the database:
1. Include a langugae column for each table. Repeat the values for each language. Say i have a country table which has 100 countries in it. Then my design will contain 500 rows (100 for each langugae)
2. Create a separate table which will contain the translations for all the 50 tables in with a foreign key to the parent table.
Which is more efficient out of the above two.

View 4 RepliesI'm new here and really, new to asp.net except the very basic things.
I am trying to create a very simple (I think simple) web form with five textboxes and three dropdown boxes and one submit button. The user enters information in the textbox fields and selects from the dropdown lists (which are populated from the database), hits enter and the database runs the query and returns information on a separate page (or can it return to the same page via panels?) The original page returned to a separate page using server transfer.
I have this page already existing in asp but feel that it would be much better served in asp.net.
Can someone point me to a post where I would guess this has been answered many times?
How do I submit the new data to the database, update the records and return the query?
I am working on a search engine application and was hoping there was a way to take multiple fields from the database and combine the values (separated by spaces) into a single virtual field, without having to actually add it to the database
Let's say I have 2 fields, FirstName and LastName - can I take these 2 fields and combine them into a Name field where Name = FirstName + " " + LastName
What I'm going to be attempting has a lot more to it than that, but if I can get an example on how to achieve that, I can apply that same principle on a larger scale
ways of doing this with AND/OR, I want to combine multiple fields into a single field
Is there anything missing in IIS 6.0 that prevents me from (Insert into table) using MS-Access?
Explain: The application works fine under Visual Studio 2008 IDE the insert into table works fine with no error, Also I tested with hosting provider and works fine with no problem. but now I have published the same exact app in a dedicated server windows 2003 with
IIS 6.0 .NET framework 2.0 with latest service pack I gave IIS_WPG write/modify access to the folder where MS-Access database is located and database but at the time of insert an error pop-up. I need to install in the Server or settings in the IIS to recognize my MS-Access db is it some office runtime that I am missing. (BTW I am using OLEDB connection string in my C# )
Using System.Data.OleDb;
I can retrieve data off of it with no problem but when I try to insert is when it fails I thought the problem was Access Rights but I do not think is the case.
What would be the best database/technique to use if I'd like to create a database that can "add", "remove" and "edit" tables and columns? I'd like it to be scaleable and fast. Should I use one table and four columns for this (Id, Table, Column, Type, Value) - Is there any good articles about this. Or is there any other solutions? Maybe three tables: One that holds the tables, one that holds the columns and one for the values?
Maybe someone already has created a db for this purpose? My requirements is that I'm using .NET (I guess the database don't have to be on windows, but I would prefer that)
I have 2 assemblies with the same name but with different version 1.0.0.0 and 1.0.0.1. I have installed it in GAC and want to use 1 of these versions during run time from my C# application(for e.g - based on locale) in asp.net 2.0.
