Access :: Reading Data From Access With A Linked Table (pointing To A Access Table On Another Location?

Sep 7, 2010

Here's a short explanation of my asp.net project.

1) the default page loads, it will read the Windows Login of the user opening the page.
2) I'll check if this login exists in a table stored on the webserver.

In this Access Database, there's a 2nd linked table, pointing to another access table on a network location. Now, I want to read data from this linked table. However, at this moment I receive an error:

"The Microsoft Jet database engine cannot open the file '\<ip><shared-folder>statistics.mdb'. It is already opened exclusively by another user, or you need permission to view its data".

Some extra info:

- The network folder has read and write permissions for everyone

- the user and group permissions on both access files are set to read/modify/administer for the Admin user (on the tables I want to read from)

- IIS authentication on the server is set to "Windows Authentication" (this is needed so I can read the Windows Login from the user). All other authentication modes are disables (like anonymous, ...)

- When the error occurs, no other program or process has access to the statistics.mdb (so, it can't be locked by someone else)

- the web.config files access connection string looks like:
<add name="AccessConnectionString" connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\<IP><shared-folder>statistics.mdb;User Id=admin; Password=;" />

Like I said before, in this statistics.mdb file, there are 2 tables. One normal table, and another linked table (pointing to a network location)

Searching for solutions, I discovered the following:

- if I don't use linked tables, everything works fine (however, I have to use this linked table)

- even if I connect directly to the table in the network I receive the error. So, I'm pretty sure I don't have sufficient rights to read from this table.

I read that not the Admin user is opening the file, but actually a user called ASP.NET. This user doesn't have the correct rights to do this. However, I'm not sure if this is true.

Forms Data Controls :: How To Show Data From A Related Table In A Gridview / Entitydatasource

Feb 23, 2011

I am using an ADO Entity Model for my ms-sql database.

My database has a Resellers table which has ResellerID (primary key, int) and Name columns along with other data.

I also have an Orders table which contains OrderID (primary key, int), OrderDate, ResellerID (foreign key to Resellers.ReselerID).

If I just do a query like:

[Code]....

I am able to reference order.Reseller.Name just fine with no problems.

However I have an EntityDataSource on my page as follows:

[Code]....

Notice the Include="Reseller" attribute in the datasource... I also have a GridView tied to that datasource as follows: I cut some of it off for breavity:

[Code]....

Now what I have listed above will run with no errors, but what I want to do is replace the column that displays "ResellerID" with the equivilant to order.Reseller.Name. In other words I want my grid to display the reseller's name rather than the numeric ID.

I have tried to change the DataField to "Reseller.Name" but that will generate the following error:

A field or property with the name 'Reseller.Name' was not found on the selected data source.

Is there anyway to do this without me writing a custom select statement in my code behind?

Forms Data Controls :: Gridview Column With Data From Related Table In SQL Db?

Aug 18, 2010

I've got a gridview that is databound with LINQ in the code behind. One column shows the id from the table. I would like to show a more human friendly product name that is associated with that id number but is from another table. Thought I had it figured out by entering a Template field in the gridview tags (in the .aspx page) and an item template within that with

<ItemTemplate>
<%Eval(Products.productName")%></ItemTemplate>

but when I try to build it says this can only be done in the context of a databound control.

Can I add this column within the gridview tags or does it have to be done from the code behind?

ADO.NET :: Checking For Valid Related Table Data In EF?

Nov 7, 2010

I've always been a bit unsure how to check for the existance of properly referenced table data.

In my situation I have various tables related to each other in many-to-one relationships where the "1" side can be deleted without the reference fields on the "many" side being updated (nulled).

I have FK relationships set up in my MS SQL server database but have turned off the FK constraint enforcement (and cascading update/delete) so that I can delete records from the "1" side but leave the keys for those deleted records in the records on the "many" side. This is something I really need to do for my web app design.

Web Forms :: How To Import Exsisting SQL Server Table To Access Table(new Table)

Dec 10, 2010

my main intention is that, the exsisting table of sql server database(.dbo) with 1000's of records, that should be import to a new access database table(.mdb).for example if we want to had a new table in db2, of exsisting table in db1 with some conditions by using "select * into New_Tabel from (select * from Exsisting_Table where <Condition>) as objectName". Here the new table is created and records inserted in one execution in db2. The same work should be done for access(sqlserver db --> Access db).Here the new access database table with given name (as string_sysdate) must be created dynamically by clicking a button (multiples time creating new table).Is there any query or c# code for sql server database to access database.

Access :: Combine Items From Two Table Rows Into One View Row?

May 8, 2010

Working in Access, I need to create a view which takes values from two different records in another table and puts them on one row in the view. I'm having a hard time doing this since both row items come from the same field in the original table (actually in this case, using views instead of tables).

I have two queries I try to join together, but come up with the wrong results:
vwComp1:

SELECT q.CompStatus, q.EQID, c.CompsID, q.LastName, q.FirstNameFROM _EQ AS q, Comps AS cWHERE q.CompStatus=1 AND c.CompsID=q.CompID
vwComp2:
SELECT q.CompStatus, q.EQID, c.CompsID, q.LastName, q.FirstName
FROM _EQAS q, CompsAS c
WHERE q.CompStatus=2 AND c.CompsID=q.CompID
vwAssignment:
SELECT vwComp1.*, vwComp2.*
FROM vwComp1, vwComp2

This does fine in the vwComp2 part of vwAssignment, in the sense that it displays the correct name information, etc.; but for vwComp1, it just takes the name and other fields from the first row of vwComp1 and repeats it on every row of vwAssignment. This is really strange because vwComp1 and vwComp2, when displayed individually, each correctly puts the names in each row; something like this:

Bob White Rhonda Red
Bob White Freda Freschetta
Bob White Linda Lime
Bob White Jean Green

--when it should read something like this:
Bob White Rhonda Red
Fred Redd Freda Freschetta
Jim Brown Linda Lime
Rob Black Jean Green

ADO.NET :: Display Value From Related Table?

Jan 18, 2011

I have 2 tables:

User(Id PK, TitleId FK, Name, Active)

Title(Id PK, Text)

Title is a lookup table of titles (Mr, Miss,...) and its got a relationship with table User by TitleId.

Now I'm trying to display the data in a web page using .net and Entity Framework. I'm using a ListView control and a query as a source. it all displays fine except for the Title.

Here is my code:

MyEntities _entities = new MyEntities (); User user = new User(_entities); IQueryable u = (from x in _entities.Users where x.Active == true select x); ListView1.DataSource = u; ListView1.DataBind();

and the code in the front end:

<asp:ListView ID="ListView1" runat="server" EnableModelValidation="True" DataKeyNames="Id"><ItemTemplate> <tr> <td> <%# Eval("Id") %> </td> <td> <%# Eval("Title.Text") %> </td> <td> <%# Eval("Name") %> </td> </tr></ItemTemplate><LayoutTemplate> <table ID="itemPlaceholderContainer" runat="server"> <tr runat="server"> <th id="Th2" runat="server"> Id</th> <th id="Th1" runat="server"> Title</th> <th id="Th3" runat="server"> Name</th> <th runat="server"> </tr> <tr runat="server" ID="itemPlaceholder"> </tr> </table></LayoutTemplate>

How do I manage to get the Title Text associated with a User to display on the ListView?

Sorting A GridView Column Related To Other Table?

Jun 10, 2010

i have a GridView bound to a DataView. Some columns in the DataView's table are foreignkeys to related tables(f.e. Customer). I want to enable sorting for these columns too, but all i can do is sorting the foreignkey(fiCustomer) and not the CustomerName.

I have tried this without success(" Cannot find column ERP_Customer.CustomerName "):

<asp:TemplateField HeaderText="Customer" SortExpression="ERP_Customer.CustomerName" >

A tried also the DataViewManager, but i've a problem to detect the table to sort:

[code].....

I have to apply the sort on a distinct table of the DataViewManager, but this table would differ on the related tables.

I have bound the TemplateColumns in Codebehind in RowDataBound-Event f.e.:

Dim LblCustomer As Label = DirectCast(e.Row.FindControl("LblCustomer"), Label)
LblCustomer.Text = drCharge.ERP_CustomerRow.CustomerName 'drCharge inherits DataRow

What is the recommended way to sort a GridView on columns related to other tables? I could build a custom datatable with the customername instead of the foreignkey and bind this column to the TemplateField. But then my huge dataset in the model makes no sense anymore.

EDIT: I have a model with a Dataset. I'm binding one Datatable(ERP_Charge) from it to my GridView(actually i take a Dataview from that Table). In this Datatable are columns that are related to other Datatables in the Dataset(relations are defined). When i want to make the grid sortable its no problem on the columns that belong to ERP_Charge.

But the columns with foreign keys to other table could not be sorted because the Gridview shows f.e. not the CustomerID but the Customername. I get the Customername in RowDataBound. Normally i would join the tables and add a Datacolumn for the Customername.
