API To Hide Non Plug And Play Devices In Device Manager?
Feb 24, 2012
I'm writing a Windows Forms application in VB.Net 2010. The application's purpose is to recreate the Device Manager in VB.Net. The idea here is to capture the information provided by Device Manager and store it in a database. In turn this information could be used as a configuration management tool.
My device tree is coming along nicely, with one minor exception. There are hidden devices that Device Manager does not display by default. Show Hidden Devices causes Device Manager to display these devices. My Device Manager displays them by default. I want to duplicate the Device Manager behavior of being able to hide and display these devices in my appilcation. I have had some success with this task in that I am able to hide the Plug and Play devices that are marked as hidden by windows by use of the "Don't Display In DM" flag. There is the small issue of the Non Plug and Play Device Class. My question is this... Is there a similar flag for Non Plug and Play devices? I have found a reference to the PNP_DEVICE_STATE and IRP_MN_QUERY_PNP_DEVICE_STATE IRP. It contains a flag
PNP_DEVICE_DONT_DISPLAY_IN_UI. My problem is that I cannot find any guidance as to the structure of this API declare and the coding needed to use it. I'm not even sure if this API will be helpful in accomplishing my task. I want to hide the Non Plug and Play devices and device class in my tree. Can someone please assist me with the locating an API that will accomplish this and the proper coding of the API in VB?
I am using Visual Studio 2010 Ultimate and Running Windows 7 Ultimate with all Service Packs and updates applied.

Been a long time since my last thread but here we go.I'm using VS.NET 2010 Prof Beta at the moment and I'm trying to list all Nic Cards and their settings into a text box. I succeeded with a script from the web (which had an error in the first place) and some adjustments to it.
It lists all hidden devices too (as to be shown in Device manager: Show hidden devices) I worked my way around it and let it jump to next if it doesn't have a IP address, but I find this a bit clumsy and want to really skip them if they are hidden and not just the way I did this now.
Plus it still does show the same NiC (different name, same MAC#) in the list because it has an IP, but in Device manager this one is hidden.[code...]

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Shell("mmc devmgmt.msc")
End Sub
End Class

Using the mciSendString command I am able to play avi, mpeg, mp3, etc. but I am unable to play mp4. Here in this web-site it says I can play any videos provided that I have the correct codecs. I am able to play mp4 using my other media players (eg. vlc player). How can I play mp4 videos or how can I make the MCI device auto detect the necessary driver type and play the videos ?

This works for XP, VB.NET 2003/2005/2008. This example does not work on Windows Vista.
Add a ListView, and Timer to a form.
{Timer must have the Elapsed Event}
Code:
Public Class Form1
Const WM_COMMAND As Int32 = &H111
Const MF_ENABLED As Int32 = &H0
Const MF_GRAYED As Int32 = &H1
Const LVM_FIRST As Int32 = &H1000

I have written an application in Visual Basic 2010 that I would like to hide from the Task Manager Application Tab, if possible. It's fine if it is listed in the Processes tab.
The purpose of the application is to allow users to postpone a restart following software update installations that require restarts. The application includes a form the user's must interact with so it can't be permanently hidden from view on the desktop. I am basically looking to mimic the WSUS Windows Update dialog which allows users to postpone restarts.
VB6 has app.taskvisible which is no longer included in VB 2010. I have seen a lot of discussion around this topic but no real solutions.

I have a function that will allow me to edit the manager property of a user here:
Public Shared Sub SetManagerProperty(ByVal de As DirectoryEntry, ByVal pName As String, ByVal pValue As String)
'First make sure the property value isnt "nothing"

But what if the manager is not in the Company OU? How can I edit this to search for him in the entire domain?

Im trying to open media player (full screen) and play a movie. When i create the file path like so: Dim MoviePathVTS As String = String.Concat("""" + tempMoviePath, " \VIDEO_TS\VTS_01_1.VOB" + """")
It wont play the file but if i do it like this: Dim video1 = """F:\Movies\DvD\Angels and Deamons\VIDEO_TS\VTS_01_1.VOB"""
It plays fine? the file paths are the same including the extra "" but it just refuses to play. I need the top one because i have many movies in a treeview.
Heres my code
Private Sub watchNow_Click(ByVal sender As Object, ByVal e As EventArgs)
'get the position of the selected node
Dim i = movieTreeView.SelectedNode.Index

I have a Browser application written using the .NET webbrowser control. As I understand, the 'webbrowser' control is based on Internet Explorer.
So, I was wondering if it is possible to use the add-ons or plug-ins (like Adblock, IE7pro etc.) that were developed for Internet Explorer with the webbrowser control.
This will really save me a lot of time as many of these plug-ins provide the functionality that I am looking for and are freely available.
