I've noticed running in a PE environment and seeing the "Nerd Herd" MRI software, I was wondering if anyone can tell me now to recreate this using VB.NET. I want to show the system info over the background if possible.
View 2 RepliesI'm trying to expand my programming horizons, and LINQ and Lambda Expressions have popped up as some apparently very important topics. As I began reading articles on Lambda Expressions, it appears that Lambda Expressions are built heavily on the concept of Delegates. As I began reading articles on Delegates, it appears that Delegates are built heavily on the concept of callback functions. As I began reading articles on callback functions, .[code]Can anyone out there give me a simple, clear, concise definition of callback functions? Do I need to learn C or C++ to fully understand these concepts? Maybe a better question is: What do I need to know to be able to understand Delegates (they've always somewhat mystified me) and LINQ/Lambda Expressions (I haven't looked into these too much, but they're mystifying, too)?I don't mind doing research, but google searches are giving me way too much information.

So, when I logIn, I go to a form called "Options", I would like to know how to only show the information about the user that I've loggedIn ?

im using as usual vb express 2010 right now on winxp, but planning to make the programs fully suported on vista & win7.
First heres my structure on public class:
Structure cartas
Dim numero As Integer
[Code].....
and the richtextbox4.text has paragraphcs or vbnewlines however u wanna call them.
Saving it on a txt file looks like this:
7:John:Marcelo:this is first paragrah[]this is second paragraph[]and this is third
note i use [] to simulate the squareish paragraph thingie that is used in a textfile. since if i try to copy it here, it will automatically convert itself into an actual paragraph.
Anyways when i try to load the file using readline i only get the first paragraph displayed and all the rest of this specific text unexistent.

View 5 RepliesI am trying to read the pc system information so that I can retrieve the time and date format.
My code below:
Dim Info As System.Globalization.DateTimeFormatInfo
Info = System.Globalization.CultureInfo.CurrentUICulture.DateTimeFormat
Debug.WriteLine(Info.LongDatePattern)
Retruns in debug: "dddd, MMMM dd, yyyy"
So I have 2 questions;
1) Why is there, a dd after the MMMM.
2) My company has small franchise branch offices round the world - France, USA, etc. What I am trying to do is get the date format so I can decide what country I am in - then when I print out the date on my order labels I can change the date format to suit Americans or Europeans etc.

I have created a project that shows a splash screen first and then shows the main form once the main form has been fully loaded. I only want to show my splash screen once the main form has completely loaded in the background. My main form by itself takes like 3 seconds to load, so I would like to display the splash screen for about 3 seconds and then show the main form because the main form will then be fully loaded, but instead it shows the splash screen for 3 seconds and then the main form still has to load anyway.How can I load the main form in the background and then show it when it is fully loaded?

View 3 RepliesI have built a recursive file system crawler that amasses file system data from a file share. I use the FileInfo object to get my metrics, however, I am finding that in especially deep file structs, that the ol' 260 character MAX_PATH MS bug crops up ':8-0:'. This puts me in my angry place, since I do not seem to be able to get around it no matter what kind of programmatic tom-foolery I try.
