View 1 RepliesI 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.

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?

View 1 RepliesI 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.

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.

I am connecting to a data stream that pushes data continuously and when I tried to set up a network stream I just could not connect and kept getting the 'not found' error. I used the httpwebrequest with webrequest.keepalive = true and started to consume the data by reading into a buffer and then appending to a stringbuilder. Once the stringbuilder reaches max size I flush it to a text file. The problem is that I get disconnected from the data stream because I am not reading the data fast enough. I need to keep the connection open and read the data while ensuring data gets stored in text files. If I use method "CONNECT" it does not connect to the stream.
While (True)
webrequest = DirectCast(Net.WebRequest.Create(url), HttpWebRequest)
webrequest.Credentials = New System.Net.NetworkCredential(username, password)
webrequest.Method = "GET"
[code]....
should I increase the buffer size and if so what is the max? that would mean I can read more data at a time and keep up with incoming push. Disparate here.
ACtually also I noticed that it gets stuck on this line
numbytesread = responseStream.Read(bufferread, 0, BUFFER_SIZE)
and then eventually I get disconnected.
