View 1 RepliesI am having so trouble with the ToUpper() procedure with strings. I am using LINQ to find unique values in a list of objects. In that whole process I set the values to compare to all lowercase in order to get a proper list. My goal is to populate a dropdown list with the values. I'm attempting to set the first letter of of the string to uppercase and keep the rest lowercase however the toUpper() procedure is not working?

I have a list of objects, each object has a score attribute,The list of scores needs to be combined on the player ID to become a totaled score or series. My current thought process is to For Each through the list of individual games, and add the score attribute to a new list of scores with the same objects. So one list would be like:
clsGame(ID Number, Sore)
dim ScoreList as list(of clsGames)
ScoreList.Add(New clsGame(11, 244)
ScoreList.Add(New clsGame(11, 333)
ScoreList.Add(New clsGame(11, 444)
Then go through combining on like ID's to make a new list of games, that would actually be the series.
Dim SeriesList as new list(of clsClasses)
For each game as clsGame in ScoreList
'cycle through the list of series seeing if an ID matches, if so add the score onto that ID
Else

Now I don't know how to add the player if its not in the seiries list without doing a heck of a lot more for each statements. If I add it after the end if then it will be added even if it is in the list..I tried playing around with List.Contains method, but I could only see if it contaned the exact same values i.e
SeiresList.Contains(game)
and because the scores are different (series vs single game) it wouldn't match, and I don't know how to see if it contains an object with just one of the attributes the same...

I have a user control that inherits the FW ListView and I need to dispose of two objects when the form's disposing of it's objects. Here's what I've concluded already, am I on the right track?
[Code]...
long story short, I have created a ListView type control, using UserControls for the parent control and the ListViewItems. Most the of the control is written and works fine, right up to the point where I tried to replicate the 'Control.SelectedItems(0).Index' property and the 'SelectedIndexChanged' event.
Each child object knows its index value, and could pass this value via the SelectedIndexChanged event (assuming this is how it works in a normal ListView control -- user clicks on an item, and that item fires an event updating the selected index value in the parent object).
How does the child object raise an event in the parent object? I have a feeling this could be done with Delegates, but I'm still learning about their usage.

Whenever I work with applications involving database I have this habit of declaring a global variable that holds reference to a Connection object and keeps it open throughout the lifetime of the application and closes and disposes it accordingly at program exit.I've been doing this since my VB6 days and still doing it now in dotNET. I've read a lot of articles regarding this practice and most of them states that it has great impact on connection pooling. Does this also mean something when my application connects to a database file (i.e. MS Access, flat text files)? Is it true that the DataAdapter and Command objects open and close the connection?

The problem I am experiencing has to do with using DataGridView.Member to access a BindingList.
My app has a UserControl called MaterialsControl, on it lives a DataGridView name dgvLineItems. Using the designer, I've set the DataSource for dgvLineItems to the MaterialsControl. MaterialsControl also has a "Items" Property. "Items" is a BindingList(Of LineItem). dgvLineItems.Member is set to "Items." The LineItem class implements INotifyPropertyChanged
Presently, when I add anything to Items, the DataGridView does not show any changes.Alternatively, when dgvLineItems.DataSource is set to Items (which to my knowledge can only be done manually), anything added to Items appears in the dgvLineItems.
Just for clarification, the DataGridView I'm using is for output primarily, the user will be able to delete values from the view, but not edit them. Insertion is done through an event handler.
I'm working on some code that was developed by the previous developer of an application and I don't understand why he used a certain syntax for IndexOf().This is the code (MyString is just an example of the string being searched for): [code] I can't seem to find any documentation for this unless it's inside of a loop where the number after the comma is incremented.

View 2 RepliesI'm using VB.Net 2008 .NET 3.0.I am not sure of the proper,or best, way to use Settings and Resources. For now I use the default project wide My.Settings and My.Resources.I have a class that I would like to reuse in other projects, so adding project wide settings or resources in each project doesn't sound proper, nor does creating constants and variables within the class itself.
I'm guessing there is a way to give a class its own resource file, and maybe even settings file, but I'm not sure how to do it. I tried adding a resource file with the same name (but with .resx extension) and I got a weird error saying I was trying to edit a resource that is apart of another project. I continued, but it didn't seem to be what I wanted and I wasn't sure how to access that new resource.I'm not currently concerned with internationalization, but it wouldn't hurt to understand how that would affect what I'm trying to do.

View 4 RepliesI am fixing up a visual basic program using visual studio 2005, specifically in visual basic. I am currently attempting to format the datagridview used to display data from a database. The values from the database being displayed are a mix of integers (used for displaying information such as number of units sold) and floating point values (used to display revenue, etc). I need to format all the values to display as integers (by simply truncating the decimal places, not rounding) as all (including the values that should already be integers which are appearing with two 0s following the decimal place). I have used the round function as follows round(value, 0, 1) which as I understand should get rid of all decimal places by simply truncating them, however I am still left with two 0s after the decimal place. Next, I went to the designer view and edited the columns property of the datagridview so that they are all set to be numeric with zero decimal places, yet the decimal still remains. I followed that by going back into the code and change any CType() that were decimal to Integer and still no change.
