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?

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]

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.
Has anyone ever come across a way of a way to create an app that kind of mimics what Terminal Services manager does in Windows2003/XP.
I would like to write something that would either go and query a farm of server every n secs a get me a list of users logged in, there process's etc or do maybe type a username in and it goes and finds the user in the farm and returns their details.
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.
I'm trying to hook the keyboard to make some action when I'm running a DirectX application. I want to press some keys like "F2" or "pagedown" when I'm running dx app and see msgbox appears. Can anyone show me the code?
Basically, I have an app that communicates with a server. I need a way to monitor all the sent and received packets that are being transmitted through the app. I've been killing myself the past two days trying to figure a way to hook into ws2_32.dll to monitor these packets but I can't find a way!
This wont give me an error, but it doesn't happen anything when I mouse down on the Control.
the same doesn't work if I put it in the user control.
Private Sub StartDrag(ByVal sender As Object, ByVal e As MouseEventArgs) Dim Box = CType(sender, Control) Box.Tag = New DragInfo(Form.MousePosition, Box.Location) End Sub
I have been trying to build a game bot in vb.net.One of the main problems is getting access to the text the game prints on the screen so I have been trying to hook the games calls to the windows api drawtext and textout functions.I have been hunting for examples of how to set up a hook in vb.net for a long time without any luck.I have found it impossible to translate examples in old school vb, C++, and C#.For convenience's sake I would like to use the freely available deviare and/or easyhook libraries.
Im making an application that is keeping an eye on an external application that does not have an API. I'm interested in getting notified when the external application changes its main window title. My idea is to somehow register a hook that will notify my application.

I'm looking for a book that is pretty much A-Z for LINQ programming from Visual Basic. I am particularly interested in LINQ to SQL. I've found "Programming Microsoft LINQ in Microsoft .NET Framework 4" and while its description sounds interesting, there is no discussion on the book at all . Do any of you have any experience with this book? If so, what do you think of it?
I just wonder that somone can give me propositions for some good books to learn VB.net / VB2008.. I know the basics.. So I think of not a book like for dummies.. Just something more a step forward for new things to learn.
i am searching a good book to learn ADO.NET 4.0,book should be excellent technical overview with practical examples,I want to learn ADO.NET Where should I start?
What I'm Not looking for:Now, just to be clear, i'm not looking for VB6 to C#.Net content, as i know there are a few of those out there.Also, I know about that "syntaxconversion table" website, where it compares VB.Net to C# language features in a side by side table. I am not interested in this either, already know about it.I'm also not looking for a converter, which converts C# code to VB.Net and visa versa, i know there are a few websites which do this and already have the addresses.Finally, I'm not looking for a C# book or resource that caters to current programmers, but specifically to VB.Net programmers!
What I Am looking for:To learn C# (VS2008 or preferably VS2010 version) given that i already know VB.Net 10.0 (VS2010)... as there are many things related to .NET that i won't have to learn again if i can find something that will leap me from vb.net to c#, many bits of the CLR, how .NET works etc... since the languages are the same in what they do, and what they use to do them, i don't want to have to re-learn all this again. The only difference is really the syntax, but also how the C# language differs in dealing with certain things, what default expectations/behaviours are in various scenarios etc...
The set of differences and similarities between C# and VB.Net are so unique that neither of these languages likely could share this unique set/combination of differences and similarities with any other language. So my point is, it really needs to be C# for VB Developers oriented, otherwise it'll almost cetainly be inappropriate or a re-hashing!
The problem is in the line that contains address.save(filename) the part address.save is underlined. When I backspace over the save, it gives me the options of what can go there and save isnt one of them. I am coping this out of a book.[code]...
May I expose my "small" problem?Here, i'm following a course in my University, called Introduction to Programming, there are only beginners in our class. i'm also a newbie, to say so.And some stupid students were not paying attention so he gave us a crazy assignment for Friday 30th.This is what his assignment consists in. I have created a PDF file from his requirements and some samples of Code.[url]
