I created a local Database in VB2008 with 4 tables, the problem is that I have a textbox in one table and a combobox in other table and I want that the information that I put in textbox appear after in combobox from the other table... that's possible?
Table: Filmes ... Field: NomeTextBox
Table: Tempo de Aluguer ... Field: Nome_FilmeComboBox
How could you, update the fields on database if its data type is Y/N, and the method of updating is a checkbox??
View 1 RepliesThere are lots of questions about this but I've not been able to solve my problem using the answers to any of them (after many, many attempts..)
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.
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 does 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.[code]I'm only trying to get the ID column populated, the rest should be fine as they're all from textboxes.

View 4 RepliesI have data entries in my database that have a common field. For example:
account_id type user_id
1 new 1
2 old 3
3 new 1
4 old 1
I am using a query like this(mysql): SELECT account_id, type, user_id FROM table WHERE user_id = 1
This is just all theoretical. The problem that I am having with this is it is only returning the first result in this case account_id 1. How can I get it to find all the results with the user_id 1 because in the way I am thinking that it is failing is that it is finding only the first result and then ending?

I'm trying to design a words game that's give you the first two letters from the word and you insert the rest to make a word (for now I'm just using "co" as example and I have just one table in the database for it). The word will be written in textbox to be compared to a database field. If the word exist in the field the word will be displayed in a label with blue color and the score will increased by one if not the word will be displayed in the label with red color. This should happen three times with three words and I have different label for each one.
the name of my database is database1 and it have one table "A" wich contain "Comp" and "word". I tried this game with array of word before and it was working. Now I'm trying to use database instead of arrays but its not working. [Code]
