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.

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 want to add DirectX capabilities to my project and I don't feel like messing around to learn WPF at the moment. How can I include DirectX into my project running VS2010 .NET 4.0. I know MS no longer supports managed code for DirectX but is there an API module or something I can get.

View 10 RepliesI'm using using System.Graphics for my latest project (A simple 2D application). Problem is, it gets a horrible FPS and I'm only drawing 8x8 tiles (usually 10-12 is enough to bring it down to 12FPS).
A friend of mine suggested that I use DirectX. He also suggested XNA but I opposed because I don't want my clients to have to install the XNA distributional. DirectX is common enough (to my knowledge) and I can just include the dll's if I need to.
So, my search began. I've been looking only for DirectX 2D tutorials for VB.net. I've had no solid success thus far. In truth, all I need to do is be able to draw bitmap x at position pos.
I've been using System.Graphics and a hacked up bitmap as my buffer thus far so I'll go for any improvement that I can get.
I'm using VB.net so I'll be ok if you give my one for C#, I'm pretty good at being able to read it (and I have a nice converter too). I would just prefer VB.net to save time.
I decided to add some 3D rendering to my project and found an interesting little quirk. DirectX doesn't like to work under the AnyCPU Platform; it won't run. Instead you have to assign it to a new platform x86 under the Configuration Manager; which makes debugging difficult because if your doing User Controls they won't load.
