I have a project which contains a large number of lookup tables, and I have all of these lookup tables represented in a single typed DataSet, which contains TableAdapters for each lookup. I've designed an editor for these lookup tables, which should allow editing of one of these at a time. My front-end is written in VB and WinForms, the back-end is a SOAP web service; I can successfully pass the changes to the DataSet back to the web service, but can't find a way to use a TableAdapter to update the single table that has been changed.
What I'm trying to do is instantiate the appropriate TableAdapter for the updated DataTable by sending the name of the table back to the web service along with the DataSet, then referring to the TableAdapter with a dynamic name. The normal way to instantiate a TableAdapter is this:
Dim ta As New dsLookupsTableAdapters.tlkpMyTableTableAdapter
What I'd like to do is this, but of course it doesn't work:
strTableName = "tlkpMyTable"
Dim ta As New dsLookupsTableAdapters(strTableName & "TableAdapter")
Is there any way to achieve this, or am I taking the wrong approach altogether? My other alternative is to write separate code for each table, which I'd prefer to avoid!

I used this way to make my shopping cart system :
Click here to see the example
when I add a product to the shopping cart it adds it very well but the problem is in the session, it stores it in the server not in the client browser.
so if some body visit the website from another computer he can see the added products on his browser while it should be empty.
Is there a way to save it on the client side instead of the server side ??

View 2 RepliesI am currently working on a program, that you enter certain values/text in and it organises it into a word document automatically,
I found a code online, which has worked a treat, However I'm wondering what lines of code I would need to:
1. Add Bullets or Numbers
2. Add a new line of text (I can add a new paragraph but I don't want a huge space between the two lines)

I am using a string builder to set up an html table row by row so that it can be emailed. I currently gather my information from the database using a data reader and while dataReader.read, I use stringbuilder.Append to add each cell value to the table.The issue is that after about 200 rows, the html breaks and displays a cell value above the table in the email. I have tried changing the cell padding, but this was not successful.
View 2 RepliesI am storing a session variable that a user types into a textbox. With their valid input, their session gets created and they get a little more functionality than the regular end users of the site.I was wondering if it is possible to find a way to add someone's session variable to the end of a URL. This way we can email a link to one of our clients, they click it, and their session has automatically begun. They already have the textbox to enter their code into, but I was told that it would be much easier for the users to just click a link that will start their session.

[code]If I wanted to get Part Name for multiple PartIDs from OrderDetails, how would I go about doing this? Would I use two DataTables? I'm confused as I cannot see an efficient way to do this. The only thing that I can think of is to create a DataTable with SQL:[code]and then maybe use a For loop to take each PartID, create another DataTable to find the PartName for that and then give this to a variable. There could be up to 10 PartIDs to search through and I don't want to have variables such as PartID1 PartID2 etc. [code]

I have been doing some listings from database, from the table "Clients", however, when it arrives to the field "Status", like it was expected, it displays to me numbers (1, 2, 3 or 4) these numbers have a relationship with another table, called "Status", which have: Single, Married, Divorced and Widower (according with those numbers).
So, I'm using a DataSet to list all the field, how can I retrieve the text in the table "Status" according with the IDClient instead of retrieving numbers?

I need comparing value from the same table for my final project.
Example :
Table 1 :
SubjectCodeClasses
Sub Aclass 1
Sub Aclass 2
Sub Aclass 3
Sub Bclass 2
Sub Bclass 3
Sub Bclass 4
Sub Bclass 5
Sub Cclass 6
Sub Cclass 7
Sub Cclass 8
...
My task is, I need to compare the classes in the subject. Sub A with class 1, class 2, class 3 have to compare with Sub B and Sub C. if classes from Sub A exist in Sub B then the output is 0, if not the output is 1. then Sub A again will compare with Sub C and the rest. After Sub A compare its value with other subject. Sub B will start comparing with all the subject and so on.
Below is the concept.
Sub ASub BSub C
Sub A001
Sub B000
Sub C100
