View 5 RepliesMy students are working on an ASP.net VB application for a Web Programming competition and we are having problems with a page where we want an URL string to return all values from our database. Here is the page: [URL] If you use the jobs by category menu on the left side, if you select a job category (ie retail) it will pull up all the jobs from that category. By using a query in the URL like this: [URL] What we need is an option that would pull up all of the records regardless of category. So we made a menu option that passes the value "all". Like this: [URL] We use this information for the dataset we created (we're using Dreamweaver, ASP.net VB and and Access Dbase). We made a dataset SQL as follows:
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin and jobcategory = ?
ORDER BY jobs.dateposted DESC
This works fine if a value is passed. For example if "retail" is picked from the menu it passes the value just fine and returns all jobs that have "retail" as the job category in the database. My problem is, how do I modify the above Select statement to show all jobs in the database if the value "all" is passed for the jobcategory. My first thought was to create an If statement that says something to the effect of:
If jobcategory = all THEN
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin
ORDER BY jobs.dateposted DESC
ELSE
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin and jobcategory = ?
ORDER BY jobs.dateposted DESC
END IF
But I haven't been able to figure out the correct syntax. I also tried making this work by using a query in MS Access:
SELECT *
FROM jobs, businesses
WHERE jobs.contactlogin=businesses.contactlogin
AND (jobcategory = @jobcategory or @jobcategory = 'all')
ORDER BY jobs.dateposted DESC;
(which does work within MS Access) and calling the query in the Dreamweaver dataset but apparently MS Access can't do that.This seems like it should be easy but so far this problem is kicking my butt.
I'm attempting to create a update form that will pull information from my database. I'm a little confused on how to get the information into the textboxes on my form. First I have my form:
[Code]....
This is where I'm getting stuck. I'm not certain what code I need or if what I have is correct. Is there an example what my next step(s) are? I would think that I need to set a variable to hold the data, maybe something like txtRace = Trim(GetString(0)???

I have some commented out as I am working one field at a time. The working fields are textboxes and the non working ones are dropdown lists. But I think it may be the field that the list is drawing from? Not sure.

I have a form wilh couple of Drop downs and text boxes and a Data Grid View which displays data from Access Table. When I hit add button on the form, I can see the data being added to the Grid View. But when I close the form and open the Access Database File (.mdb), the respective table is empty. The Access Table is not being updated. Second time if I open the form, the Grid View is also empty.I am pasting my code here.

I am starting a new project in ASP.NET (With silverlight) - I would like to get expert opinion about how to design the data access.I can use DataAccess Layer with SQL helper, but the challenge is every new field that I add needs to be added in the sql helper.I am trying to see if there is a way to design the system, so that it appears in the front end when a new field is added. I don't want to have in the ASPX files (binding in controls) I want to have ability to change items in code. Essentially I am trying to see the best option to have a database application.

I have data coming from two tables with a foreign key relationship - one User table containing users of the web application, and one Page table containing details about pages visited by each user.I would like to be able to view these data in a gridview or the like on a page. It's easy enough to just show the User table data like so (I'm using the Entity Framework and LINQ):
[Code]....
But how can I show the Page details? I'm not bent on any particular way of showing it, but the only idea I've been able to come up with is to have a dropdown list for each user in a column. But I can't figure out how to get the page data into such a dropdown list. The tables are associated with the primary/foreign key UserID.The closest I've come to finding something similar to this is this for Linq2SQL: http://weblogs.asp.net/scottgu/archive/2007/07/16/linq-to-sql-part-5-binding-ui-using-the-asp-linqdatasource-control.aspx , and this using more traditional data access: ttp://www.highoncoding.com/Articles/169_DropDownList_Inside_GridView__Method_1_.aspx . Either way, regardless of data access technology, I can't relate these solutions to my example and get it to work
So I have created a log-in screen that allows you to create a user at the same time. I wanted to make sure that if there was already a UserID registered that if a user tried to register with the same ID that an error message would show rather than my whole website crashing.
This is my code:
[Code]....
The code to place the data into the database works fine by itself but when I put it into this if statement the data no longer goes into the database.
If this the correct way to do this for making sure that a user cannot create a profile with a user id that is already present or is there a simpler way? I have tried to do it with a customvalidator but that did not work at all.
when i change page from page1 to page 2 I remember Dropdownlist in session
Session("Dropdownlist")=Dropdownlist
now when i go back to page1 I set the Dropdowlist the way what it was before i left page1
Dropdownlist=Session("Dropdownlist")
Everything its remember but when i load the page with my Dropdownlist again. The selectedindex shows default value in the control Dropdownlist.But it does remmeber old selectedindex.I got it wired with Gridwiew and gridwiew show Data by remmeber old selectedindex. Well generally I like to remember selectedindex when i go to a differente page and when i go back have it set in the control dropdownlist the way when i left the page

This code works.

I'm creating an ecommerce site using asp.net and a Access Datasource, I have used the pre-defined logging in and registering controls provided by Visual Studio 2010 which stores the user data in a SQL server.
For my site the content of the shopping cart is uploaded to a table in the access database, I need to however save the contents of the cart to a specific user ID. For example if User number 1 orders book id's 4,7,2 this needs to be saved, but if user number 2 comes along and orders 4,1,7 this needs to be saved for them as well.
So a user can have many carts, this is sorted in access but with the user ID being saved to a different database is there anyway I can link the two databases so I can say
"Save bookid's 1,2,3 in tblcart where userID is the same as the logged in user"
