If you can not pay: Either use TAPI or MS Communication control (with VB - check MSDN)
If you can pay, there are several APIs such as HAPI (check hyperterminal in your system).

Hi All,

I've been searching for days to try and obtain the list of counters available on a 2k or NT box, without using the GUI selection.

I have written some monitoring DLL's which return the counters fine, providing I supply them. I need to enumerate the counter list and let the code select apropriate counters.

Any Idea's I have been on MSDN and if I was a C++ programmer I'd have it done by now..

Any help would be great

Commonly, we use free SDK / COM components provided by the manufacturers (For example, Logitech Quick Cam provides one. See FAQs at

Given below is a code which will extract information about your machine from the DNS database and display it on your vb form:

Dim oAddr As System.Net.IPAddress
Dim Machine, ipaddress As String
With System.Net.Dns.GetHostByName(System.Net.Dns.GetHostName())
oAddr = New System.Net.IPAddress(.AddressList(0).Address)
Machine = System.Net.Dns.GetHostName()
ipaddress = oAddr.ToString()
ipaddr.Text = ipaddress
macname.Text = Machine

The above code extracts the machines ip address and machine name and displays it in your form.Now i am looking for a code which can extract the username and group name of the person logged in on that machine.Could anybody help

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

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 Smile | :)

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

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

String Literal in VB.NET?

20-Aug-02 11:16

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..

Eek! | :eek:

*->>Always working on my game, teach me
*->>something new.
cout << "dav1d\n";

Re: String Literal in VB.NET?

Paul Riley20-Aug-02 14:07

Paul Riley

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.

ANN: Release of DeKlarit Version 1.2 for Visual Studio .NET

Maria Jose Serres20-Aug-02 8:04

Maria Jose Serres

20-Aug-02 8:04

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.
