bhaps you should start with the System.Windows.Forms.SystemInformation class
I think this is what you are looking for.
Hmm...

Hi Lasse,
Thanks for the information, SystemInformation class has all the adequate methods which let me fetch the machines info,although what i want here is :- Machine username and also Group name. How do i fetch a usergroup name?

can anyone please give me sample code or example for deleting part of the string..
Dim str As String
str = "c:\temp\folder1"
how can i delete "\folder1" from str so str will be only "c:\temp"
I know how to do in c++ but do not know how to do in VB though.
Is String has any functions like CString?
in C++ i can use CString::Find('\') and CString::Right() methods.. what about in VB. any functions that will do the same as above functions???
thank you

I got it..
that's what i did
Dim fileName As String
Dim path As String
Dim index As Integer
path = "c:\temp\testing\folder"
path = frmPrinterProperties.IDpath.Text
' deleting the last folder name..
index = InStrRev(path, "\", -1, 1) ' find "\" reversly in the path string
path = Mid(path, 1, index) ' get what ever right before "\"
fileName = path & "new folder" ' now "c:\temp\testing\new folder"

You want to rotate the text 90 degs.
This is not simple 
Use the Create font api (allapi.com)
CreateMyFont = CreateFont(Height,Width, 900, 900, Weight, FW_NORMAL, Italic, UnderLine, Strikeout, DEFAULT_CHARSET, OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, PROOF_QUALITY, DEFAULT_PITCH, "Times New Roman")

 Hi,
I am getting the following error when trying to call a Windows API function from Visual Basic.NET
An unhandled exception of type 'System.NullReferenceException' occurred in WindowsApplication5.exe
Additional information: Object reference not set to an instance of an object.
The code that I wrote is :
Declare Function RFVB_New Lib "RF2VB.DLL" (ByVal lObjectType As Long, ByVal pObject As Long) As Long
Dim lerror As Long
Dim lFI10Obj As Long
Public Const RFO_FAXINFO_10 = &H10000
lerror = RFVB_New(RFO_FAXINFO_10, lFI10Obj)
The error is occuring on the last line.
Please suggest the cause of the error.
Thanks

Question:
I have an intranet site that I need to snag the user's domain name so I can stuff it into a mail message. Does anyone know of a way to grab this info from a serverside script?
Thanks,

This code works in VB6, however you may be able to just wrap it into a ActiveX COM component to work on the web.

hey all,
I'm trying to do a very simple regular expression but VS.NET is barking at a simple line of code.
At the top I have:
Imports System.Text.RegularExpressions
And in my code I have:
Dim r As Regex()<br />
r = New Regex("\d{2}[a-zA-Z]+", RegexOptions.IgnoreCase Or RegexOptions.Compiled)
The error message is:
C:\DavidCode\NETBeast\WindowsApplication2\Form1.vb(74): Value of type 'System.Text.RegularExpressions.Regex' cannot be converted to '1-dimensional array of System.Text.RegularExpressions.Regex'.
I'm not sure I understand why except that my regex may not be a string literal. In C# I can just do @"..." but in VB.NET it isn't working..
*->>Always working on my game, teach me
*->>something new.
cout << "dav1d\n";
|
|
|
|
|
It's because of those parentheses after Dim r As Regex.
What you're saying here is "give me an array of Regexes" then you're saying assign this new Regex to this array variable which just isn't possible.
Paul

|
|
|

Thanks Paul...
Brain Fart; I keep writing things as:
Regex r = new Regex("..")
and then remembering I'm in vb.net and not adjusting properly -
*->>Always working on my game, teach me
*->>something new.
cout << "dav1d\n";

how to create directory in VB?
I know in c++ mkdir(..).
let say i want to create c:\meme\testfolder
|
|
|
|
|
In VB6
<br />
MkDir "c:\meme\testfolder"<br />
In VB.NET
<br />
IO.Directory.CreateDirectory("c:\meme\testfolder")<br />
Paul

Use the
CreateDirectoryEx<code> API ;) <br />

We are pleased to announce the release of DeKlarit 1.2 for Microsoft Visual Studio .NET!
DeKlarit is a RAD tool that integrates into Visual Studio .NET, aimed at developers who want to rapidly deliver .NET applications. Unlike other tools with long development cycles from design to executable applications, it allows you to create robust applications in record time.
DeKlarit provides a declarative way to describe your business objects, based on which it creates and maintains a normalized schema and generates ADO.NET DataSets and DataAdapters. When there are changes in the Business Components structure, DeKlarit creates a new database schema, migrates the data from the old schema to the new one, and regenerates the .NET DataSets and DataAdapters.
Version 1.1 was released in July 2002 and added several important new features to version 1.0. Now, version 1.2 incorporates a new type of Business Component and several productivity features:
New features since v1.0:
· Reverse Engineering Tool: Start your Business Framework from an existing database and have your .NET application done in no time.
· Web Services Generator: It allows you to automatically build a Web Services layer on top of your Business Framework.
· Windows Forms Generator: It generates complete Microsoft .NET applications that work with your Business Framework.
· Custom Metadata Properties: The ability to define custom metadata properties for DeKlarit objects and attributes that can be used in custom code-generation tools.
· Event-Triggered Actions: The ability to execute actions triggered by specific events in the business rules.
· Role-Based Security: It allows you to use .NET role-based security in your Business Frameworks.
· Support for using external SQL views, with the new External View object.
· Support for paging in DataProvider’s DataAdapters
· Better Help integration and content
· Samples and documentation in Visual Basic.NET
· Improvements in the Reverse Engineering tool
· New Built-in metadata properties for Business Components and Attributes
· Performance improvements for loading large projects.
To see how easy it is to build the .NET PetShop application with DeKlarit, download it at www.deklarit.com/samples/petshop.msi.
As you can see, the DeKlarit Team has been extremely busy updating this version for our clients.
We encourage you to download the latest technical documents at www.deklarit.com/technical.
There is a 30-day limited trial version for download at www.deklarit.com/trial.
Best regards,
The DeKlarit Team

No, two!
I really would want a Web Services Generator which allows me to automatically build a Web Services layer on top of my Business Framework!
And the ability to define custom metadata properties for DeKlarit objects is making me die for it!

Hello,
I've got these 2 lines of code, they each do the same thing, but one produces VERY different results. Can someone please tell me what is going on. It is simple painting code. In a user control, I overrided the onpaint event. The 2 drawing calls inside are practically the same, and produce the same effect on the control. HOWEVER, when you resize the form so the form border clips half of the usercontrol, it creates speckles on the control when you move the form off the control slowly. Take a look:
BTW, my usercontrol is inherited from system.windows.forms.button
<br />
Protected Overrides Sub OnPaint(ByVal pevent As System.Windows.Forms.PaintEventArgs)<br />
MyBase.OnPaint(pevent)<br />
Dim p As New Pen(Color.Navy)<br />
p.DashStyle = Drawing.Drawing2D.DashStyle.Dot<br />
<br />
With Me<br />
'THIS CODE SPECLES FUNNY<br />
pevent.Graphics.DrawRectangle(p, 4, 4, .Width - 10, .Height - 10)<br />
<br />
' - OR -<br />
<br />
'THIS CODE WORKS JUST FINE<br />
'ControlPaint.DrawFocusRectangle(pevent.Graphics, New Rectangle(4, 4, .Width - 10, .Height - 10))<br />
<br />
End With<br />
End Sub<br />
Can Someone Please Please let me know, because I am trying to implement a "focus rectangle", but I don't want to use ControlPaint.Draw.... because I need color customization and ControlPaint.Draw... Doesn't have working color customization.
Thanks,
ERIC FRANZ

hi, i still dont understand the concept of "stream", more specifically:
System.IO.Stream
System.IO.MemoryStream
Here's a code fragment in VB.NET:
Dim HSBCWC As new Customer()
HSBCWC.ID = 08346
HSBCWC.FirstName = "Paul"
HSBCWC.LastName = "Bowie"
...
Dim stream As MemoryStream()
Dim serializer As New XmlSerializer( Customer.GetType() )
serializer.Serialize( stream, HSBCWC ) QUESTION 1: Why not serialize to a string as supposed to a MemoryStream? It would be much simpler rite?
...
stream.Flush() QUESTION 2: I dont understand why we need to flush? flush what from what? I thought HSBCWC has already been "flushed" to stream?
stream.Seek(0,SeekOrigin.Begin) however, I do understand why u need to Seek (rewind the stream).
...
Dim reader As New StreamReader(stream)
message.body = reader.ReadToEnd()
stream.Close()
SmptMail.Send(message)
I'm a newbie and pretty confused why we need "streams" in general.
help! 
SHAME

"The MemoryStream class creates streams that have memory as a backing store instead of a disk or a network connection."
I thought MemoryStream is a memory object (data in RAM). So, "Flush" will flush this data (already in memory) to another memory location???
help!
