As I learn more about programming, I've discovered that I'd like to occassionally save bits of code for either later use or scrutiny.I was considering just pasting it into Word, but that seems inefficient when it comes to finding it later.

View 3 Repliesnote, this is homework. It's not worth much, but i really need to learn how to store things in arrays. my biggest confusion is that i have no idea how to store something in an array, have the program run again andcontinuouslybuild the array andthen display the array in its current state (by like clicking a display poll button) and then still allow it to build more once more data is entered.Here's the whole assignment. I don't really understand how to start it and the problem above is my biggest frustration!ite a Visual Basic application that can be used to determine the best Super Bowl commercial. The choices are as follows: Budweiser, FedEx, E*Trade, and Pepsi. The application should allow for the user to enter a voter's name, gender and select a commercial from a list.
Create a Vote structure that will contain the voter's first name, last name, gender and the selected commercial. Each time a vote is entered, the information should be added to an array of Vote structures.Provide the ability to save your data to a sequential access file. The program should also be able to read an existing file of vote data into an your array of Vote structures. Doing so, should eliminate any data that may have already been in the array.
I'm trying to get a complete understanding of Objects . Namespaces etc and think I'm pretty close.I've created A basic Vehicles class and a car class that inherits Vehicle.Through user input I've created several cars and displayed the information in a listview.My question is what is the best way to store my cars (don't say garage!) so that if a user clicks on the associated entry on the list box that they can then alter that specific instance.

I have a slight problem understanding how the following code works, it's specified in an example I have that the code is to check if FileName is a valid path for a text file and other things of course but I'm just interested in that part(checking it's a valid path). Here's the code:
Method save()
aWriter As StreamWriter
Try
[code].....
Private m_HolderName As String
Private m_Balance As Decimal
Private m_Dat As Date = Now
this approch is correct or not.
When running the code the data does not save within the data base there are a few errors with in the code ......
View 2 RepliesI'm using the book titled "Database Programming with Visual Basic .NET and ADO.NET: Tips, Tutorials, and Code".
I'm going through the chapter that has me do data binding by setting the properties of a DataGrid and TextBoxes.
It had me drag a DataAdapter onto the form and had me generate a DataSet. This part works fine. It also had me set the binding through the Text propert of each TextBox. This also works fine as it displays the correct data as the user navigates through the DataGrid.
I think there may be something missing from the code samples in the book because saving the data back to the database is not working and even no errors are reported.[code]...
I have a block of code which is used to save some information to a text file. I need to use this a few different times in my app.I could just copy and paste it each time but that seems messy and is adding unnecessary code. I'm sure I can just save the code once and reference it when I need to. I think it's done in either a module or a class or something

View 1 RepliesI have a dataset along with code for validation. When I use a datagridview and setting the EditMode to OnEnter I get the red exclamations telling me that I have an error when this is needed. This works all good. when I click the save button on the BindingNavigator, the application saves the record even when this validation is showing. How do I filter up this validation code through a datagridview and stop the program saving the data? If you need the code for more information, I will add this to the forum.

What is the best way to store 4 bits from a byte in VB.Net? Where best means:Most straightforward method of storage from a Byte type.The easiest to work with while performing bitwise operations.Straightforward conversion of the bits to other types.Storing them in a BitArray via it's constructor reverses the order of the bits. This means that attempting to get the value of the first bit will require looking for that value in the last entry in the BitArray.
View 3 RepliesI have a vb .net ArrayList that I would like to store in one field on my Ms SQL 2008 database. Is it possible to put it in and get it back out as an ArrayList? I'm guessing i need to break down the Array some how and store it as a string, then rebuild it when reading back as i dont see any datatypes for sql that are for arrays. Which is a bummer for me! edit - The ArrayList stores a set of quote ID's. There is no limit to how big it is so it could hold 1 or 1001 different ID's
View 3 RepliesIm working on an Asp.net / VB.net website and coming from a C# / WPF background things are still a little new to me. I have declared a DataTable like so: Public notificationList As DataTable And I have then used the Page_Load event handler to populate it and bind it to a control on my page, which all works fine
[Code]....
However in another method i need to be able to access this DataTable, yet whenever I do it always appears as nothing. Do I need to be storing this value elsewhere like in the session etc?
Basically, I want to have a database that's lightweight and I won't need to install amillion other things on my clients computers for them to access this.I just need a simple method of reading and writing values so that they're not hardcoded into the program. I could do MySQL (which is what I'm very familiar with), but it doesn't need to be making calls remotely.

View 3 RepliesI am trying to retrieve a 'tag'(Is it called that?) from an XML webpage. Once I make a post request from my vb.net app it sends a command to my online webserver and redirects me to a page that has entries that change each time. The page that im redirected to that changes each time looks something like this:
<mainpage> <id>hello</id> <random>176</random> </mainpage>
What vb.net code would I use to retrieve the id (In this case 'hello') and store it in a variable.
I have the following code that I use to convert a picture into bytes.
Code:
Dim strImageFilePath As String = _
LblPicture.Text
Dim fsImageFile As New FileStream(strImageFilePath, _

This then gets used to store into an SLQL 2000 VarBinary field.I thought the above would work but its only letting me save pictures that are under 8k in size, but I need to be able to save much bigger files than that.
