View 4 RepliesVS 2008 Proper Use Of Resources For A Class?
Jun 8, 2010I 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.
View 3 RepliesVS 2008 RichTextBox The Proper Solution?
Jun 20, 2009I want to display some text for a user - blocks of text about "vendors" - that can be scrolled.
I might want the first vendor to be a different color - or be bold.
I might want certain fields in the "text blurb" about each vendor to be bold - or underlined - or a different color.
In VB6 I would have used a RTB - would that still be the solution??

VS 2008 How Many Proper Payloads Server Received
Aug 24, 2009I took a look at System.Security.Cryptography.MD5 class about using a checksum for a UDP program i am making.Basically i want to use it, to ensure the server is receiving what the client sends it, in a way that the server can make note of it receiving properly without having the client keep track of how many proper payloads the server received. The reason i need a checksum is because the client is sending a random hex payload, so i cant have the server predict what it should receive the same way as i have it working with the sequence number.I dont fully understand how i could implement this to my code. I believe i should make a public property in my packet class, but im having trouble implementing it with the way i coded my program. [code]
View 39 RepliesVS 2008 Proper Way To Pause/resume A Thread?
Oct 6, 2011I have a thread running on my application that checks a database every so often to decide whether or not to update nodes in a treeview.
Each treeview node represents a document and I have an open button that opens the document for the user.
When the document is opened, I wanted to suspend the thread that refreshes the node list until the document is closed.
I have MyThread.Suspend and MyThread.Resume. But the document viewer is on another thread.
I created functions for suspending/resuming the thread in the application. I have delegates in the viewer to call those functions from another thread. But I'm still getting an Error. "Thread is not user-suspended. Cannot be resumed" or something of the like.
But I realize that Suspend and resume are obsolete functions, so what class or objects should I be looking into and if it didn't take up too much of your time, a small example as well?
VS 2008 - Displaying Proper Columns In Console Game?
Jan 17, 2010I'm making a console game that shows some data:
#: Item Name Item Slot Cost Item Price
in that order. The thing I want to do is to make it come out in nice even columns...but I can't seem to make it do that. It comes it out in nasty uneven rows that don't look attractive...
Basically, here's what it looks like now:
1. Sword Slots: 2 Price: $40
2. W. Stick Slots: 4 Price: $1
I want to get each column to line up nicely with the other (since I control the size name).

DB/Reporting :: Proper Use Of ADO.NET?
Nov 18, 2009Whenever 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?

Proper Two Way Binding?
Mar 21, 2010The 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.

View 4 RepliesProper Formatting For Datagridview?
May 18, 2010I 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.
