List Name Of All Connected Devices On Lan?
Oct 28, 2010i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

View 6 RepliesCode For Loading List Of Plugged In USB Devices?
Sep 11, 2010This is my code for loading list of plugged in USB devices:
Private Sub Button5_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button5.Click
ListBox4.Items.Clear()
For Each Drive As IO.DriveInfo In IO.DriveInfo.GetDrives
[code]....
I would like when a button (lets say buttontest) is pressed it will show all files of a CD (only MP3) into ListBox5, then when buttontest2 is pressed the files in ListBox 6 will be copied from the CD to the selected USB device?
VB Code To List All Webcams Or Video Capture Devices?
Jan 19, 2010I am trying to add the ability to select a camera to my program to start with I need to list the currently installed devices in a drop down menu much like what is used in MSN's webcam selection but the only thing that I can find that comes close is

View 1 Replies.Net 2010 API To Hide Non Plug And Play Devices In Device Manager?
Feb 25, 2012I'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. 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.I am using Visual Studio 2010 Ultimate and Running Windows 7 Ultimate with all Service Packs and updates applied.
VS 2010 Using 3 Or More Sound Outputs Or Multiple Sound Devices
Jul 21, 2011I'm creating an application that will have 3 streams of audio. I can get 2 streams playing easy enough using DirectX AudioVideoPlayback and setting the balance for each Audio Instance. However, I need a 3rd Audio instance to play out of another output such as the Rear or Centre. An alternative would be to be able to select a different sound device in the machine to play the 3rd audio stream.

Add Support For MTP Based Devices?
Apr 3, 2007I'm writing a media management tool and want to add support for MTP based devices.I've been reading through the SDK docs and with the help of some C# examples have managed to make a start on getting some VB code working.
I've come across a few anomolies that I hope someone can help me with!In the examples IPortableDeviceManager.GetDevice appears in C# to receive a string array. But in VB.NET it appears to only receive a string. I have a similar issue with IPortableDeviceManager.GetDeviceFriendlyName which according to the C# samples appears to receive a char array, whereas in VB.NET it is accepting a UShort.

View 3 RepliesForms :: Hide Hidden Devices
Dec 9, 2009Been 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...]

View 4 RepliesInitiate Internet Data Connection On WM6 Devices?
Jun 22, 2010I am currently porting (well really totally re-writing) a project to run on WM6 devices. I need to initiate a GPRS data connection (or any internet data connection really, shouldn't matter if its GSM or CDMA) before I can get the data I need (actually sync. a database over the cell network - Sybase via Mobilink) because right now its basically saying I have no network connection when I make the call to sync the db.
If I open Internet Explorer on the device, it initiates the data connection, and I can then go back into my program and get the data no problem. This isn't an acceptable solution however.
How can I initiate the internet data connection?
