Number Sorting, Lowest To Highest, With Text In Front?

Nov 14, 2009

I'd like to know how to sort an array that has entries with numbers after text.

I have a list of four entries:

Book 1
Book 2
Book 11
Book 12

Using Array.Sort(aBooks) returns

Book 1
Book 11
Book 12
Book 2

Is there a way to have it sort lowest to highest like 1 2 11 12 instead of 1 11 12 2?

Program Using Arrays And Functions - Highest / Lowest Number

Jun 14, 2012

I am new to using VB2010 (and coding in general). Also brand new to these forums . Okay so I am making a program that: allows the user enter the number of customers served for each of 12 months into an array. The application should calculate and display the following statistics: total number of customers for the year, the average monthly number of customers, and the months with the highest and lowest numbers of customers. Use inputBox to get user input. Do not accept non-numeric or negative numbers.

The problem that I am having is that I do not know how to display which was the best and worst month. I imagine I need something that targets the highest/lowest number and finds the text in the corresponding index but I'm not sure how to do this.

Datagridview/Query - Finding Highest Number And Assigning It To A Variable?

Jan 9, 2010

I don't know if I worded this properly, but I have a mdb query that I display in a Datagrid on my form. The first column is TransactionNumber, which is the primary key and a running total (ex. RackingTransactionKey=RackingTransactionKey + 1). What I need to do is when the form is opened, find the highest (last) TransactionNumber from the query or Datagrid and assign it to a variable (RackingTransactionKey), so I can can update it (+1), therefore generating a unique number so I can add data to the query.

VS 2008 - Finding Highest / Smallest Number From List Of Values

May 10, 2011

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.

Make Gridview Checkbox Field Update Boolean Field In Database?

Feb 7, 2011

There 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...

Transferring Data From One Field In A Table In A Database To Another Field In A Different Table But Same Database In .NET?

Jul 22, 2010

I 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.

Auto-assign Number To SQL Field?

Jan 12, 2010

Probably a simple question for most of you. I'm putting members of a group into a SQL Database so we can better manage attendance and 'points' that they earn for doing work. I've written the program in VB and have the SQL server running fine. However, I have created a separate table to handle the points and have marked the relationship between the table - the column is named 'PointID', and should be unique for each person. When I add a new user to the database, I want it to automatically assign a value to that without me having to do anything extra beyond pressing save. From this PointID, it should identify the user and it will bring up the person's points.

I got a Mysql sql database for my project. The id field is set as auto increment, which seems to function correctly. But on the form in my text field and datagrid i see a negative number, while in the database its a postitive number. I do not really plan to use the id field right now, but when i do it might cause some problems.

Anybody know why it would show as a negative number on the form(textbox/gridview) and as a positive in the actual database?
