Access :: Retrieving A Value From Database?
Aug 20, 2010
I want to be able to take a select statement like: SELECT password FROM table WHERE user_name = @user_name and compare it with what was entered in a form text box. I have tried:
AccessDataSource1.SelectParameters("password").DefaultValue
= TextBox1.Text
AccessDataSource1.Select() (not sure how this works or what to set it equal to)
I also tried to connect to the database with a basic ADO connection that I got off another forum, with no luck

I'm trying to retrive images from SQL (2005) using ASP.NET 2008
At present I have a business object layer and a data access layer to get some data from the database. This works fine but now, i would like to also retrive an image along with the data.
part of my business object layer is shown below, how can i incorporate the image into this.
I have a DLL file which will take care of displaying the image in the web page once i have retrived it.

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.

I have two tables Users (Userid, Name, PhoneNumber) Applications (ApplicationsId,UserId, ApplicationName, ActiveDate)
Every user will have more than 1 application.
In Nhibernate using lazy loading I can get the users data along with all the applications for every user. So, I used to do something like user.applications[i].Applicationname to get all the applications.
But, Now how do i retrieve all the applications along with the users data using oracle commands. I know how to get one application using joins. But, how do i retrieve multiple applications and store it in a IList.

I have an aspx form that is meant to add a new prescription for a doctor system. I've created the database and dataset needed, but the problem is that the doctorID and patientID has to be able to select from the database, not entered in as a plain text. The form look something like this (I did this in DetailsView in MS Visual Studio 2010):
DoctorID: [textbox]
PatientID: [textbox]
prescription details: [textbox]
Insert Cancel
as you can see, only the prescription details needed to be entered in and the doctorID and patientID needed to be selected from the database (in a dropdown list maybe) and it shouldnt allow any text to be entered in. I did the above tables using a DetailsView in Microsoft Visual Studio 2010. However I can't seem to make the doctor and patient ID field be dropdown box which allow me to choose the current doctor and patient in the Doctor and Patient table in the databse. Can anyone tell me how to do it with Design View in Visual Studio?

I have a page which will retrieve data base on drop down lists and place the data onto a gridview. When the data was entered, each field was entered with multi-selected and delmited by a comma. In the database, some fields will have a string with multi information delmited by the comma, for example, Chicago, Atlanta, NYC will be recorded and place in the field in the database. I'm trying to search now but with a dropdown list with Chicago, Atlanta, and NYC being an individual record. If the person selects NYC, all of the records from NYC will appear even though Chicago and Atlanta are part of the string.
The following is the code for the current page:

I'm using update panel in the master page. Half of my web page will retreive the data from the database in dynamic. As, my update panel is in master page(with ajax loader), it is taking much time for every event. Is there any other advanced method to get the data from the database instead of using update panel.
