Hi, is there any good free, documention on visual BASIC express edition? I am doing an A level, and I want to get the programming out the way as soon as possible. OR, are there any free podcasts I could get that I could run on my IPOD(The original)? Thanks for any suggestions!

Do these use the same langauge? I ask because I was typing into my school progam ( visual BASIC 6 ) Form1.Print "Hello" and it worked then I typed the same thing into my express edition version, and it didn't work, why is this?
|

There is no such thing as visual basic express. Only Visual Studio express for VB.NET
Visual basic 6 is not 100% compatible with Visual Basic.NET

Sorry, it says (On the top of the IDE) Microsoft Visual basic 2005 express edition. Can you tell me what the actual code should be for the VB.Net express edition?
|
|

VB6 is an old ( out dated and no longer supported ) non OO language that Microsoft has pretty much discarded. VB.NET Express is a free version of VB.NET 2005, which is a new, OO language that happens to use VB syntax. They are almost completely different from one another, your VB6 program will not work in VB.NET. Tell your school that VB6 is rubbish, it's dead, and VB.NET Express Edition is free. That's what they should be teaching you.

Ok, does that mean, that the express edition I have is up to date and is the right one. I need to get books etc. for visual BASIC 2005?
|
|
|
|
|
Yes. VB.NEt 2005 is the one to learn, between that and VB6. So, get some books, check out the information online, and remember you can ask any question you like here, but you'll do better if you try to do stuff and ask when you get stuck.

hi,
I am creating a .txt file using .net.
The name of the file will be the selected item in a list box.
eg if i select "name" in the list box then the fule name will be name.txt.
My problem is if i select "name/sa" in my list box, it says path does not exist as it does not take it as one name.
it takes name as a filder name and sa as a file name.
how can i make the "/" to be part of the name?

Not sure, but perhaps you can use Linux ?
/ is NEVER part of a filename, it always denotes a path. If you're taking free text, you need to not accept this value, or the others that are unacceptable in a filename ( rename a file in explorer to that, and you'll get a list from Windows ).

By default, in all Windows versions, the "/" character is reserved for command line parameter switches and cannot be used in path names:
FORMAT A: /S
The "\" character is reserved for file system path spec's and also cannot be used in a filename.

Hi everyone,
In VS2003 we have ASP.NET Web Application on Visual Basic projects but i cant see it on VS2005
does it exist on vs2005 or no.
Thanks

File/NEw/Web site. You don't need a sln file anymore, you can create a website just by pointing to the directory it's in.
ASP.NET 2.0 is very different from 1.1.

I am trying to hook keyboard events(basically disable printscreen key) from windows service. This code works perfectly fine when i put it in a form but when i try it from windows service it compiles properly, installs also without any error but does not disable the required key! I have tried almost all combinations to try and execute this code for example: converting class into a dll and then calling it from service code, include the whole code in a different file etc. but all of them do the same thing, i.e compile and install without errors but not work! i am including the code here for your refference. and yes i am working on visual studio 2005.
********************************************************************************************

Of course not! Windows Services run under a seperate (not visible) desktop. Only one desktop can receive the input focus at a time, so according your service code, you never get any keystrokes.
Try going to the Services manager, finding your service, then enabling the option to "Allow service to interact with desktop". This might take care of the problem.

Hi all,
I wrote some vbscript code to find place holders in Excel cells (e.g. yadayada<<comments>>blahblah) and replace them with some user defined text. I tried Cells.Replace method but it only works if the string is less than 255 chars... I searched the MSDN try to find a work around but no banana... Any help will be highly appreciated

Hi guys, I'm new to programming and the first language I'm trying to learn is VB .NET.
It's going pretty well for me, but I have a question and I was wondering if anyone here might be able to help me.
I have a text box set up to get information from the user, once that is computed an anwser anywhere from 0 minutes to 180000 minutes. I was wondering if there is a tutorial, or a few lines of code that would be able to change the raw data of 180,000 minutes to days/hours/minutes in three different text boxes.
For example, if the user entered a number which got them 129,564 minutes that would display as 89 days 23 hours and 24 minutes.
Thanks a lot, aqzman
EDIT:
I thought this code might work, but it never. Haha.
If Time > 1440 Then
Time = (Time / 60)
Time = (Time / 24)
txtDisplay.Text = Time
End If
If Time < 1440 Then
Time = (Time / 60)
txtDisplayHour.Text = Time
End If
If Time < 60 Then
Time = (Time)
txtDisplayMin.Text = Time
End If

You're on the right track. You need to use the Mod operator ( it's % in C#, I suspect it's Mod in the ever literal VB ). This will return to you the remainder of your division. So, if you have 63 minutes in Time, Time Mod 60 would give you 3, the number of seconds.

I have a label control and I want to modify its text from within a thread (example shown below), but I get a runtime access exception. How do I access controls from a thread?
Imports System.Threading
Imports System.Threading.Thread
Public Class Form1
Public thrd As New Thread(AddressOf MyThread)
Public counter As Integer = 0
Public Sub MyThread()
Do
counter = counter + 1
lblThreadCount.Text = "Thread Count = " & counter
Sleep(100)
Loop While 1
End Sub
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
lblThreadCount.Text = "Thread Count = " & counter
thrd.Start()
End Sub
Private Sub Form1_FormClosed(ByVal sender As System.Object, ByVal e As System.Windows.Forms.FormClosedEventArgs) Handles MyBase.FormClosed
thrd.Abort()
End Sub
End Class
|
|
|
|
|
Add the following line to the top of the Form1_Load event:
Control.CheckForIllegalCrossThreadCalls = False

Assuming the .NET Framework 2.0, you're looking for the DriveInfo[^] class and it's TotalSize property.
In using .NET 1.x, you can get it using the WMI Win32_LogicalDisk class and the System.Management namespace.
