I have a little chunk of code that open the device manager by using the command line. I want it to open a specific tree eg: Monitors .Is there a way to pass a parameter to the device manager to open this specific tree or item?
Public Class Form1
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Shell("mmc devmgmt.msc")

All I need is a list of devices installed in a list box
Once again, I come on my knees to ask for your guidance :P Well, actually I was hoping to see if anyone could someone make up a code similar to this idea xP. [code] Anyone knows how to do this? Basically just list every device connected. Doesn't have to be in the specific paths, just the names of every device

View 5 RepliesI'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 mainly a Java/C++ developer.The program displays the tree structure and allows files and folder to be selected. The program is getting errors with FileSystemTreeView when trying to return nodes on a system with a reserved partition.Here is what is happening: tree.SelectedNode = tree.Nodes(0) 'returns error with system reserved partition.calling, GetDriveList() will properly return all the drive letters - and not throw an error. Only when trying to get a tree.Node() or tree.load() is the error occurring.

View 4 RepliesIs it possible to define my list of strings like in 'good old' VB60, to use only on ebyte of memory for each character? .NET always seems to store any string as unicode, which doubles the required memory. The case is that I have a huge list of strings, all of the same size. It is about 50.000.000 items, 12 characters each. You can imagine I am running out of memory in no time. I tried converting them to arrays-of-bytes but in that case I loose the possibility to perform a "LIKE" statement in a FOR-EACH loop to check for a specific item.
