I have a form with a button that says "Open CSV".I want to be able to click that button. Then browse for a .CSV file, and after I select the file, populate a combobox with all of the headers of the .CSV.I would then be mapping these headers to fields in my database, then import the .CSV data into my database.
View 3 RepliesThe tables described herein both utilize composite keys. I have a parent table that stores eligibility information per "case". The child table stores eligibility information regarding each individual associated with the case. The child records are differentiated by pin number to make them unique in the child table only.
I am using NHibernate v3.1 with Fluent NHibernate v1.2, both acquired via NuGet packages. The entities are mapped in using the Fluent NHibernate auto-mapper functionality. Any custom mapping is done in the mapping override method for each entity.
Another thing to know is that these tables do not have a "primary key" defined in DB2. They only have "unique keys", which are what you see in the composite key definition below (see code).
T0026_AG_ELIG is the name of the parent table and the corresponding POCO class.
T0265_AG_IN_ELIG is the name of the child table and the corresponding POCO class.
Problem:
The problem is that when I execute the query, all the data is queried, the parent record is successfully mapped to the class, but the returned child rows do not map into the collection on the parent class. NHibernate does generate the queries for the parent and child data. When I execute my own query against the database, the correct data for the conditions does come back. For some reason, the child records are just not being bound to the property on the parent (T0026) class.
Question:
What do I need to do to get the multiple rows coming back from T0265_AG_IN_ELIG to map to their corresponding class and load properly into the specified collection property on the parent class (T0026_AG_ELIG)?
Collection Property of Parent (T0026_AG_ELIG):
Public Overridable Property IndividualEligibilityRecords As IList(Of T0265_AG_IN_ELIG)
Mapping Override for Parent (T0026_AG_ELIG):

I'm working in vb.net creating an asp.net web application. I have an SqlDataSource and a GridView on my page.
I want to change the DoNotMail boolean value represented by a Gridview checkbox and automatically update in the database if the checkbox is checked from 0 (False, Will Mail) to 1 (True, Won't Mail) here is the code I used. [code]...
is it possible to do a two way sync on the entire gridview when the user hits a button so you don't have to do an update every time a row is changed? because the user might check the box and then check another box then uncheck a box and it would be a lot of updates...

View 1 RepliesI am creating a database in VB.NET for a movie rental place. I currently have three forms;
Member Information
DVD Information
Borrow DVDs
What I would like to do is when I am viewing a member's details, if I click a button 'Borrow DVD for Member', the member's ID number transfers over to the Borrow DVDs table in the Member ID which also would hold some information from the DVD Information table, but I'm sure if i can figure out how to do this firstly, I will be able to apply the same rule and work it out myself.I have been trying to use a query statement like;
INSERT INTO [Borrow DVDs].[Member ID] [IN goodstuffvideos.mdb]
SELECT [Member Information].[Member ID]
FROM [Member Information]
but that has been coming up with error codes and completely not working.
Borrow DVDs table fields are: Borrow ID, Member ID, DVD ID Number, Hiring Fee, Borrowing Limit?
DVD Information table fields are: DVD ID Number, Title, Rating, Hiring Fee, Borrowing Limit Member?
Information table fields are: Member ID, Family Name, Given Name, Address, Town/Suburb, Postcode?
The error coming up is; Error in INSERT statement. Unable to parse query text.And under that it says The query cannot be represented graphically in the Diagram and Criteria Pane.

View 4 RepliesI'm trying to make an appointment scheduler here. The table has an AppID column which just increments 1 every time a new appointment is added. That works fine. It also has an ID column that gets a unique doctor ID assigned to it so the program knows which doctor has which patient.
Now, when I try to add a new row, no matter what I try, the ID field gets a -1. I've tried assigning it the doctor's ID that I'm currently browsing as well as hard coding it to be a "3" and it still shows as -1. So this means that while it [B]does[/B] save and update the new row, it adds that -1 in the ID column and thus the program can't tell which doctor has it so it won't show in my program. I don't know if this is because I've tried so many data sets that it's getting them confused or what, but here is the code that I am using to try to save this:
