I'm making a system where only the supervisors can use the Ctrl+Alt+Del to bring up the menu (Vista / Windows 7) or start taskmanager (XP)Since my application will not be running on anything less than XP I don't need to worry about 95, 98, ME, 2000, etc. I have this code so far (found on here and a little edit by me) but the Ctrl + Alt + Del doesn't get stopped like I thought it would.
Note to use this from within Visual Studio you might have to untick the box for "Enable the Visual Studio hosting proccess". In VS 2010 it is found in Solution Explorer > My Project > Debug > Enable Debugers > Enable the Visual Studio hosting proccess I've found several ways to stop taskmanager loading but not to stop the menu being displayed. This code is working except for my little problem with the Ctrl Alt Del menu and has been tested by me with VS 2010 .NET4 on Windows 7

disable Ctrl-N on a WebBrowser control using VB or JavaScript? I couldn't find any straight or working answers on Google so I thought maybe we could finally get a straight answer for the next person thinking the same thing.

How to disable Ctrl-Alt-Del in Windows 7 when the application loads? I'm looking for an example that disables Ctrl+Alt+Del when the app starts, and enables the combination again once it finishes.I found an example that disables the combination on Windows XP, however it doesn't seem to work on Windows 7. Why? Is it not allowed on Windows 7 to disable Ctrl-Alt-Del?Also, I'd like to know how to run an application as admin on Windows 7?

I've read many posts about disabling Alt+Ctrl+Del and Ctrl+Tab, etc. I'm not looking to do that. What I'm trying to do is create an app which will be hidden, and then need to be unhidden from "anywhere." For example, if I have an Excel spreadsheet open, I want to be able to use a combo like Ctrl+U to Unhide my program, but I do NOT want it to underline the text in the cell I'm currently in (which Excel will normally do). I don't want to worry about disabling or changing shortcut combinations for Excel, Word, etc.

I have created my own web browser by dragging the web browser control into a form using Visual Basic 2008 in order to host my ASP.Net pages. However, it is a requirement of the project I am working that users should not be able to use hot keys, especially print screen, ctrl P, ctrl C, and ctrl V. There are no other controls on my form, so how can stop users using these keys, but only in this browser? Further, my asp.net page uses an iframe tag to show a word document, and again, I need to stop them from copying and pasting from the word document into another word document through the browser. Can I stop them in my browser in app stack?

I am using a 3rd part dll file (SolidWorks EModelView.dll, COM file) that has a version of 9.2.0.128. When I add it to the resources for the application, however, the AxInteropEModelView.DLL and InteropEModelView.DLL references show a version of 9.0.0.0. When I install the application on a client machine and try to run it, the application says it cannot find AxInteropEModelView.DLL version 9.2.0.128!

I'm working on a tool that requires overlays ala X-Fire. I'm hoping to do it in C# or VB.NET rather than resorting to C++, but the only solutions i've found for .NET cause a large performance hit (~20FPS in games). Take a look here: [URL]

I have been working on a project for some time now and I am stuck. I am trying to sense when a navigation software speaks so i can mute the volume of everything else on the computer.
my problem is that i cant properly sense the audio of the software. i am using windows 7 and vb.net. i have done a good amount of research, but i have not come up with an answer.
i am almost positive that i need to intercept the win32api call of the software to trigger the mute that i will use. i dont know how to do this, all the information i can find that is even close to this subject is for 98, nt and 2k.
does anyone know of any books (or websites) that contain information on this subject?

Is there a way in vb.net to subclass/hooking in to any controls scroll bar and change it is colours etc (I saw this once in C++ but lost it). It�s ok for MS giving us user owner drawn controls, or at the very least allowing us to draw the controls information but it looks dam write awful if the scroll bar does not fit into the GUI.

I play a midi file using this simple win32 api call:
MidiMsg = "open " & c_midiFile & " type sequencer alias mid1 notify"
ret = mciSendString(MidiMsg, "", 0, Form1.Handle)
MidiMsg = "play mid1"
ret = mciSendString("play mid1", "", 0, Form1.Handle)
Callback message MM_MCINOTIFY has a value of &H3B9 (found it using "spy++")I have to know when this message (MM_MCINOTIFY) is fired and read his parameters. In an old version of code I've written years ago in VB6 i had to use CallWindowProc and SetWindowLong win32 api, but now in VS2005 i cannot get it to work.Still I have to try with unmanaged code or are there any other ways to do this in vb .net?

I am not very familiar with VB.NET so I don't know if this is possible.Some code I am working on is setting the properties of a very large class. In the setter of each property an event is raised to indicate that the class data has changed. An event handler then serializes the instance of the class to a database.Obviously I do not want this to happen after each property is set, so I need to either have a delay before saving, or something else.I am keeping a large list of instances in a cache implementation already, so one option would be to only process the cache every now and then and save all unsaved instances in cache to the database.So I tried to see if I could derive a class from Application (and override DoEvents), but it is NotInheritable, so no luck there.

I currently have software that sends out plain text(i.e. 'X') to comm 1 port and was wondering if there was any way to capture that plain text and also respond to that port on the same compute as the port without having anything plugged into the machine (i.e. 9 pin serial cable). I am trying to avoid buy any more hardware as this is an objective to acutally cut down on hardware.
