simple and easy sendkey example., 28 Downloads; Since: August 28, 2012)][
Audio/Video Objects Direct X 9.0
(17.2 KiB, A fairly in-depth example of using the Audio/Video objects
in the DX9 library. It shows you to use DX9 for your normal media
playback and a few different interface feature. It has your usual
play/stop/pause, along with getting various
file/extension/duration/position information. It shows how to change the
position of the media, change the balance on the speakers, and changing
the playback volume. The example is a sound/movie player in one. Added
code that will automatically determine the the most popular media file
types, then select the proper class library for playback. The movie

another., 37 Downloads; Since: August 28, 2012)][
Basic/Simple Multithreading- BackgroundWorker Object

object added to version 2.0 of the DotNet Framework. It is likwiswe
compatible with the .NET Frameworks version, 3.5, 4.0, and 4.5, This

features., 29 Downloads; Since: August 28, 2012)][
Bouncing Pong Style Ball - 2005 and Higher Version
(7.6 KiB, Shows how to create and render a moving ball using the GDI+
APIs that will bounce off of the controls borders. Added a way to
control the speed of the ball. Otherwise it is similar to the 2002/2003
version. It does play a beep sound whenever it hits the wall and bounces
in the other direction. I guess this could be the start of a Pong style
game or something., 288 Downloads; Since: August 28, 2012)][
Calculator Example in VB.NET
(34.9 KiB, This is a calculator example that has your basic
Addition(+), Subtraction(-), Multiplication(*), Division(/) based
features. Inlcudes other features like Backspace, Rounding, Square
Root(sqrt), Reciprocal(1/x), Sign Change (+/-) and so on. This
calculator was made with Visual Basic.NET 2005 but will work just fine

Checking if the Operating System/Application is 64 Bit or 32 Bit
(17.4 KiB, This provides multiple methods on how to check if the
operating system and if your program is running in 32-Bit (x86) mode or
64-Bit (x64) mode. It uses 9 ways including checking a registry key,
GetSystemInfo/GetNativeSystemInfo, Environment Variables, WMI, IntPtr
size, and more! VB 2010 and Visual Basic 2012 has a feature that was
originally added in the .NET 4.0 and that is available in the dot net
4.5 framework framework called: Environment.Is64BitOperatingSystem,
which is a property that will return True if the operating system is
64Bit and False if the os is NOT 64 bit (x64) but is 32 Bit (x86). If
using those versions and you only need to know the addressing for the
operating system (OS), then go ahead and use
Environment.Is64BitOperatingSystem. Also if the registry or another
method in this example returns AMD64 or Intel64 then it IS 64-bit/x64
and not 32-bit/x86., 285 Downloads; Since: August 28, 2012)][
ClipBoard Example
(15.6 KiB, This shows how to use the Windows clipboard class from the

CPU RDTSC/Calculate Processor ClockSpeed(Processor Mhz) in Realtime
(29.9 KiB, Shows how to use my Visual C++ csRDTSC.dll file to retrieve
the cpu/processor's rdtsc value and then using that data with a '1'
(One) Second loop to calculate the cpu/processor's mhz clockspeed in
realtime. This is similar to the 'CPU Timestamp/Calculate ClockSpeed'
example in the Visual Basic.NET 2002/2003 section, except this one is
only compatible with Visual Basic 2005, VB 2008, Visual Basic 2010, and
Visual Basic .NET 2012., 23 Downloads; Since: August 28, 2012)][
CPU Usage and Data Example
(14.7 KiB, Shows how to use either Visual Basic.NET 2005, VB 2008,
VB.NET 2010, and/or Visual Basic 2012 to use Performance Counters and
the Windows Registry to retrieve various information and statistics on a
users computer system cores/processors. It will determine how many
cpus/cores are installed in the computer, and then retrieve various data
about the cpu's from the registry. It then shows how to use Windows -
Performance Counters to monitor the usage of each processor/core thats
being used, along with the Total usage of the computer. (I only added
components for a dual core cpu or less since this was made way back when
the AMD Athlon 64 3800+ X2 was new). Hopefully there was something
useful you could get from this., 25 Downloads; Since: August 28, 2012)][
CPU Usage in System Icon Tray
(39.3 KiB, This is the complete example source code to the
csCPUUsageInTray program in the software section. This program uses the
GetSystemTimes API that was added to Windows XP with Service Pack1 and
higher operating systems. Using the function will allow you to calculate
the computers entire processor or computer cpu usage. I use this cpu
usage value to both plot a graph with the cpu usage history and to draw a
text icon in the system tray to show the cpu usage as numbers. This is
similar to the SysmonLite program I made but better I guess. :), 18
Downloads; Since: August 28, 2012)][
Create/Using Managed Windows API Timers - VB 2008, VB 2010, and VB 2012
(13.0 KiB, A small example made with Visual Basic 2008 but can easily
be upgraded to VB 2010 or Visual Basic 2012 on how to use an API Timer
to run codes at a certain interval. This timer appears to be just a
managed wrapper around the SetTimer/KillTimer API Timer in the
User32.dll library. Thus, the highest resolution I was able to get was
15-16ms which is right around the GetTickCount timer resolution which is
a part of the User32.dll library as well. While this project will not
load in VB 2005, the codes will work with 05 since the timer was first
added in version 2.0 of the .NET Framework. IF you want higher
resolution Windows Timer Events, then try using the multi-media, but
Un-Managed timer event called: timeSetEvent/timeKillEvent, which has a
resolution of 1 ms., 26 Downloads; Since: August 28, 2012)][

2.0 of the DotNetFramework. The example has its own activity Logo that
is active while it is loading a website and stops when it has finished.
It shows how to make your own tool to strip all of the url tags from a
webpage, get all of the image tags from a webpage, and get the source
code of ANY webpage that is loaded. It also has working
