Retrieving information from database

Posted By:      Posted Date: September 30, 2010    Points: 0   Category :ASP.Net

Hi, 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? Cause the source view is kinda confusing for me. 

Thanks in advance!

ERROR [HY000] [Informix .NET provider][Informix]Database locale information mismatch


Hi, there is an upgrade to my infimacs server and my web application encounter this error after the infimacs is upgraded.

Below is the information on the server before/after the upgrade.

The web server where the web application hosted is running IBM Informix Connect 2.81. There is no such error before the upgrade is done.

As a developer, i have IBM Informix Client-SDK 2.90 installed on my local pc and debug the page where the read is needed from infimacs but no such error found.

The error come out only when it is hosted on the web server where IBM Informix Connect 2.81 is installed.

How to show random information with C# from a SQL Database?

I have to do the following in my web page.  Any advice and how to do this please with C# I have a table where I have a column for different states (NY, NJ, etc).  People can join the group (in my page) for each state (the state where they live).  So I have to display the newest members for each state. So the way it should work is, every time the page is refreshed/reloaded it should show the state name as a header text and the first 5 newest members for that state.  This should be random, for example initially when the page is loaded say it will show state: New York and the 5 recent members like Stacy, Laura, Mike, Sam, Mathew. Then when the page is refreshed it will show another state like State: california and the recent 5 members All the information comes from the database How should I do this?

Suggestion on retrieving data from a database

hi everyone, 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. Can someone show the right direction to do this? Thank you, Carlos The following is the code for the current page:<%@ Page Language="VB" AutoEventWireup="false" CodeFile="ExportContacts1.aspx.vb" EnableEventValidation = "false" Inherits="ExportContacts1" %> <%@ Import Namespace="System.Web.Mail" %> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <script runat="server"> Protected Sub exportcsv_Click(ByVal sender As Object, ByVal e As EventArgs) Dim objStreamWriter As IO.StreamWriter objStreamWriter = New IO.

need information on database backup

Hi, As a developer Ihave very minimal knowledge on database backups. Before reaching out to DBA I want to understand few things 1) I need to place a request to create new database on a SQL Server. There is around 540 GB space on this server but the two existing databases on this server already used 500GB space. So what option do we have to create new database? Is it a simple task to add another drive and allocate some space or use mapped drive? what options can I suggest DBA? 2) Also DBA mentioned that there is no space to take backup on this drive for the existsing database. What option can I suggest for backup incase if we plan to drop one of the database which is not actively used?

Q about retrieving data from database

Hi, I'm having a question about retrieving data. I'm using VS 2008 and I have to create a new consultation record for a patient and I've already created a database with 3 tables, which are doctor, patient and consultation. I have 10 records saved in consultation table, and I've made a aspx form which contains a DetailsView that ask for new consultation details to be added. But I have to be able to get the doctor and patient information from the database and put in the DetailsView, then fill in the rest of the consultation details. The information entered have to be written to the database in the consultation table. But I don't know how to get doctor and patient information from database and apply them into the DetailsView so that doctor who wants to add new consultation details can select patient and doctor information from the database.I was thinking maybe I need to do a query with insert statement and apply into the DetailViewthis is the query i have:INSERT INTO [Consultation] ([ConsultationID], [GPname], [PatientFirstName], [PatientLastName], [Height], [Weight], [IllnessDescription], [Diagnosis], [Date]) VALUES (@ConsultationID, @GPname, @PatientFirstName, @PatientLastName, @Height, @Weight, @IllnessDescription, @Diagnosis, @Date)as you can see, I need to get the GPname, PatientFirstName and PatientLastName from the database tables and the rest will be fi

Restoring a content database from another server/AD does not synch user profile information for new


In my SharePoint 2010 beta environment, I have user profiles synching with Active Directory.  I just restored a content database from a separate environment/domain and logged in with my current account.  When I try to create an alert on a library/item, I get the error:

“You do not have an e-mail address.  Alert has been created successfully but you will not receive notifications until valid e-mail or mobile address has been provided in your profile.”

I went to My Profile and found that the My Profile had the right e-mail address (I guess because this is on my My Site Host).

But when I went to My Settings, it did not have any e-mail address for me (I guess this is because it is at the WSS content database level and the e-mail address hasn’t yet synched from the user profile database).

Does anyone the timer job that synchs the user profile with the My Settings for a site collection in a content database?

Issue is posted to my blog with screenshots here:
