• Visual Basic Detection of Insertion and Removal of USB devices

  I am having problem with my FYP that my application is based on the detection of Insertion and Removal of a device. I am aware that this would happen using Win32_VolumeChangeEvent class or WMI. (Please notify me if I am wrong). Kindly solve this problem and send the code for Console Application in VB.NET. Please do not send code in any script language or C#. Also to get the device information. Hi, Rabtok, With your code, it is able to detect a mass storage device plugging/removing. For a non-mass storage device (e.g.: a microcontroller based USB control board), how can we detect a device plugging/removing When I plug/remove the USB device, the windows does raise m_MediaConnectWatcher.EventArrived event. Could you give me ...Show All

• .NET Development Unable to locate Assembly asdlfkjasdfkljasd

  OK, this one is a real head scratcher. I have a paticuarl application on my beta server that flips out almost every time I modify the source code. It gives me an error saying that the cached assembly doesnt exist. Sounds like a permission issue right But I've checked for all of that... and my other apps work just fine. So I google and find some info on app-pools, so i stick the app in its own app pool. Still.... same problems. I spent an entire day fighitng with this thing... all to no avail. It is a win 2k3 server with .net 1.1, and 2.0 installed. I have currently ONLY .net 1.1 apps setup in IIS. Could this be caused by a flaw in my code If so How This is extremely frustrating because its preventing me from coding :| Someone ...Show All

  Hi, I have a checklist box and I have a method that is called when the SelectedIndexChanged event fires. Is there any way to know which item in the list caused the event to fire Thanks It will be the currently-selected item in the CheckedListBox, the same as with a ListBox. The event which tells you that an item has been checked is ItemCheck, which provides an ItemCheckEventArgs with the index of the item. ...Show All

• Microsoft ISV Community Center Forums MergeSort for Double Arrays

  Hello There =) I made a MergeSort function for matrices with Double Data. I haven't found this on the web (one that works, that is), so I'm posting here, so ppl can watch, and maybe improve. To use with strings and other kinds of variables, you just have to change the compare statement, and the type (Double). The compare statements are bolded. Cya Public Function MergeSort(Doubles() As Double) As Double() Dim s As Long, i As Long, n() As Double, m() As Double Dim u As Long, l As Long, j As Long, x() As Double ' Only 1 element If (UBound(Doubles) - LBound(Doubles)) = 0 Then MergeSort = Doubles Exit Function ' Only 2 elements ElseIf (UBound(Doubles) - LBound(Doubles)) = 1 Then MergeSort = Ordena2 ...Show All

• Visual Studio 2008 (Pre-release) How to change ListBoxItem DataTemplate based on ListBox state

  Basically what I want is to use different DataTemplates for items in a ListBox based on simple states of the ListBox, like SelectedItem, Enabled/Disabled ListBox, etc... - i.e., I would be defining the following types of DataTemplates: SelectedItemDataTemplate, EnabledItemDataTemplate, DisabledItemDataTemplate. Is there an easier way than using a DataTemplate Selector The problem with using a DataTemplateSelector is that it seems DataTemplateSelectors are used for applying different DataTemplates based on values of the ListBoxItem, not different states of the ListBox control itself - note that SelectedItem is a state of the ListBox control, not the ListBoxItem. To complicate matters, the ListBox control has been abstracted into a Us ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. How do I load a 3d mesh (.x file)?

  How do I load a .x mesh into my scene The space game seems to use its own format (which it names .swm), and there's nothing in the help. I've been scanning through through the classes in the Framework namespace, but I can't see anything obvious! Is .x the recommended format for objects like this (If not, I change my question to be about the recommended format :D) If anyone knows anywhere that has some nice .x meshes I can play with, that'd be cool too. The only one I have lying around is a chair, and that's going to look a bit funny running around my game :D Oh, bummer :( So the "old" method, that would've been used in the Managed DirectX stuff won't work I don't mind using the meshes f ...Show All

• SQL Server Stored Procedures and C++

  I am using Visual Studio 2003 (C++) and have inherited a data acquisition app. The existing app has CAdoDatabase and CAdoRecordset classes, but they do not seem to be complete. The throughput is pretty high and we switched from using recordsets for adding new data to using SQL insert queries. These are better, but still not fast enough. Some of our installs are for SQL Server 2000 and some are for SQL Server 2005. I am fairly certain that I need to use stored procedures to increase the speed. Since the existing app is limited, is it possible to use the CAdoDatabase function that executes a SQL statement to execute the stored procedure All of the examples I have seen show a command class where all of the parameters have to be defined and an ...Show All
