I am not sure what is the correct way making this work in windows forms. Please any help is greatly appreciated. here is the code I am using to load the smallicons imagelist of a listview.
Imports System.Windows.Forms
Imports System.Drawing
Module ExtractFileIcons

I'm extracting icons from running processes and then adding them to a ListView. Some processes don't have icons or I can't get access to them, so the icons are sometimes all mixed up. The following is how I'm extracting the icons:

I was able to extract icons from the current running processes and then put them into a ListView.
I am trying to do the same with files in a specified directory:
vb.net
[Code].....
When I use this code, I get an error stating: "'MainModule' is not a member of 'System.IO.FileInfo'." If I remove the very first line of the sub that specifies the directory, that error obviously goes away.
So, is there another method of extracting the icon? Or must I declare the directory in another way?
I'm getting ready to check MSDN to see if I can something withing the FileInfo Class,

I was scripting a very basic process manager, with a ListView component, and it was working fine for many days, up until now.Here is the code for getting processes:
Dim Process As New Process()
Dim Count As Integer = 0
ListView1.Items.Clear()[code].....
The line of code where I put "*WIN32 EXCEPTION LINE* keeps running into an error(Win32 Exception was unhandled; Access is denied). Here is the full error description:
System.ComponentModel.Win32Exception was unhandled
ErrorCode=-2147467259
Message=Access is denied[code]....
As I said before, this had been working for several days, up until now.

TortoiseSVN and Dropbox both have Windows shell extensions that make file icons within Windows Explorer show a small icon beside the main one, showing the file's status - has it been synced, etc How can I make my application show icons beside files like that using the Windows API? Or is there some file attribute to do that?

I am trying to create a small utility that tracks desktop usage in detail, to the level of individual text boxes etc.... in other applications. However, it is proving quite tricky. I thought I had it nailed using the Windows api. The below code is just a snipet of the code but essentially it provides me the handle of the control that the mouse is over. I thought from here, it would be easy to to the same thing but to provide the handle of the control that the cursor was actually clicked on, for example, if someone is filling in a text box in an application, they would not necessarily move the mouse to get to the text box, they may tab to it. Does anyone know if there is a way to get the handle of the control that is in use?
Private Sub Timer1_Tick(sender As Object, e As System.EventArgs) Handles Timer1.Tick
Dim ptx As Integer = Cursor.Position.X
Dim pty As Integer = Cursor.Position.Y

Does anyone know of a good 3rd party reference for Win32 API for .Net where VB.Net is the target language Most API references target C as the language of choice. Frankly, I hate C and all C like languages.

We have a .NET app that needs to examine a folder that may contain COM libraries (DLL and OCX.) When we do encounter a COM library one thing we need to accomplish is to extract the GUID from the COM DLL or OCX.Is there a straightforward way to do this with .NET without using 3rd party libraries?

I have a Delphi program that communicates with a vb.net dll that I created. The vb.net dll communicates with a Fluke scope meter via an RS232 connection. I have created a program that communicates correctly via RS232, giving me the anticipated value. Though, when I package this up as a dll and access the dll from my Delphi program I always receive a value of "1", rather than the value I was expecting (most cases a value in and around 240).I know that my delphi program is definitely communicating correctly with the dll and that my dll is definitely communicating with the scope meter
Here is my vb.net code:
Public Interface IFlukeComm
Function GetReading(ByVal Command As String, ByVal PortNum As Integer) As String

A DLL file contains some images inside PNG resource type.
I can view the PNG images in softwares like Resource Hacker, Anolis Resourcer & Resource Tuner. Check this screenshot of Anolis Resourcer for more details:
how do I get the PNG image no. 5220 from the DLL file and put it inside a PictureBox? I don't think APIs like LoadImage or LoadBitmap will work.

I'm running into is some of the namespaces aren't being recognized. After searching the internet it seems I am supposed to have more than just System.Management.Instrumentation available to Import/Reference.However, that is all I can access.I need System. Management. ConnectionOptions and a few others, but don't know how to get these.Do I need to install the WMI SDK, or maybe the WMI Win32 Classes?

I am refactoring a large and complicated code base in .NET that makes heavy use of P/Invoke to Win32 APIs. The structure of the project is not the greatest and I am finding DllImport statements all over the place, very often duplicated for the same function, and also declared in a variety of ways:The import directives and methods are sometimes declared as public, sometimes private, sometimes as static and sometimes as instance methods. My worry is that refactoring may have unintended consequences but this might be unavoidable.
My instict is to organize a static/shared Win32 P/Invoke API class that lists all of these methods and associated constants in one file... EDIT There are over 70 imports to the user32 DLL.(The code base is made up of over 20 projects with a lot of windows message passing and cross-thread calls. It's also a VB.NET project upgraded from VB6 if that makes a difference.)
