Nov 15, 2010I am using VB 2008. I am trying to use the currentMedia.durationString to get a tracks lenght like shown below:

I have a problem that this does not work until a file has started playing. If i start a track and then stop it, then load a different track it works perfectly but it never just works first time.
Play A Simple Note Passing It The Frequency, Stereo Position, And Duration?
Aug 19, 2009In VB.NET 2005. i am trying to experiment with sound. I started out trying to produce a single note at a single left-right position, for a particular duration (maybe until i shut it off. with a particular frequency.It can be a sine wave, or a square wave or maybe a general midi sound. This seems to me to be a simple task, but i cannot find out how to do this.I suspect that the answer lies inside direct sound or xaudio2. I want a simple solution i don't want to have to spend 1600 hours learning xaudio2 in order to learn how to how to make a beep.The ideal answer wold be for me to write a routine that accepts waveshape,freq,volume,Stereo_Position,duration).

Find A Character At A Current Position?
Oct 31, 2011I am trying to develop a HANGMAN game and i need to implement a button where the user can click on it to "buy" letters. So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?
Private Sub picBuyLetters_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picBuyLetters.Click
Dim index As Integer = txtWordinStars.Text.IndexOf("*")

View 2 RepliesVS 2010 Getting Meida Duration
Jul 21, 2011I have been searching around and trying to figure out how to get media, specifically videos, length/duration.I know that you can use the Windows Media Player object to achieve this, however, I need to get the duration of some media that is not supported by windows media player.I am developing my own media player in VS 2010 that will be utilizing the VLC media player component since VLC is able to play most (if not all) media formats. So far I have tried playing around with "My.Computer.FileSystem.GetFileInfo("path").length" but all this gets is the media's length in Bytes. What I am trying to achieve is the format of hh:mm:ss for pretty much every format, not just Windows Media Formats, but real media, .mkv, etc.

View 2 RepliesMonitor The Current Position Of The Mouse Cursor?
Apr 21, 2009I'm trying to create a hook to monitor the current position of the mouse cursor. Nothing important, I just need to count some pixels during interface design and wanted to learn how to create a hook, so I decided to go for a hard way instead of a sane way.
I've found example code which declares the following function:
<DllImport("User32.dll", CharSet:=CharSet.Auto, _
CallingConvention:=CallingConvention.StdCall)> _
Public Overloads Shared Function SetWindowsHookEx _
[Code].....
But Appdomain.GetCurrentThreadID generates the warning: "'Public Shared Function GetCurrentThreadId() As Integer' is obsolete: 'AppDomain.GetCurrentThreadId has been deprecated because it does not provide a stable Id when managed threads are running on fibers (aka lightweight threads). To get a stable identifier for a managed thread, use the ManagedThreadId property on Thread."
I've tried using ManagedThreadID, but that doesn't work. The thread ID returned seems to be the logical thread ID of the thread, as it runs in the .net runtime, rather than the Win32 thread identifier.
Calling the function ith AppDomain.GetCurrentThreadID works, but I really would like to have a "stable identifier" for my thread.
Can someone explain to me whether it is possible to use ManagedThreadID in this context (I assume not) and, if not, the things I need to avoid in order to stop the AppDomain.CurrentThreadID from becoming "unstable"?
VS 2010 Get A Proper Hh:mm:ss Formatted Duration?
Feb 19, 2011I want a proper hh:mm:ss formatted duration, but I cant seem to get it right. I have ran through a good dozen attempts and things just arent working.
timer
Public dtStartTime As DateTime
Public tsElapseTime As TimeSpan
Public Sub tmrStartTime()
[code]....
Calling tmrStartTime sets the start of the timer, and tmrGetTimeSpan should report back the proper hh:mm:ss. For example, 11 elapsed seconds should look like 00:00:11, or 65 elapsed seconds should look like 00:01:05.
AxWindowsMediaPlayer - Current Position And Play Time Difference?
Jan 10, 2012I'm using VB 2010 Express with two instance of AxWindowsMediaPlayer in order to sync two videos (the videos are of the same thing but from two camera angles). Because the videos were started at slightly different times I've manually set the start time of each one using the following
AxWindowsMediaPlayer1.Ctlcontrols.currentPosition = 314.5093196
AxWindowsMediaPlayer2.Ctlcontrols.currentPosition = 237.1639908
The problem I'm having is that whilst the WMP clock initially displays the above times in each AxWindowsMediaPlayer, when I play the videos each starts a few seconds out from the stated currentPositions.
The video files are around 300MB each and when testing with smaller video files the problem does not seem to happen. I'm guessing the large file size is causing some delay and hence causing the problem.
DB/Reporting :: Bind These Textboxes With Current Datagridview Position?
Apr 10, 2008On one of my forms i have a datagridview binded to an Access database. It displays only first and last names of my customers in a datagridview.What i want to do now is, when i double-click on one of the customers another form will open and display details for this customer (detailed view - textboxes).
What i have accomplished so far is that when i double-click on a customer in datagridview a form opens with details (linked to the same binding source as datagridview). But the problem is that it always opens the first record even if i dobule-click second or third in datagridview.I don't know how to bind these textboxes with current datagridview position?
VS 2010 - How To Track Duration Of Functions Calls
Feb 15, 2012In our VB6 applications, we added a few utility functions for tracking the amount of time spent in a function. We did this to track performance bottlenecks. Basically, how it worked was there were two utility functions:
StartTickCount() and EndTickCount().
You would pass the name of the function in each, and the functions would use a dictionary to get the tick count when StartTickCount() was called, and then subtract the tick count when EndTickCount() was called. This wasn't perfect because it didn't of course take into consideration that calls to get tick count takes time, etc, but basically it worked for our purposes. How to make sure to call StartTickCount() at the beginning of each function and EndTickCount() at each exit point:
Private Function SomeFuction() as String
' indicate the function started
StartTickCount("MyClass.SomeFunction")
' some logic that causes the function to end
[Code] .....
Anyway, is there any functionality built in, either through the VS 2010 debugger or in the System.Reflection namespace, to do something similar in VB.NET? Basically, what I want is to log the number of times each function is called, the total amount to time spent in that function, the average number of seconds spent in that function, and the maximum amount of time spent in a single call in that function.

VS 2010 - How To Set New Cursor Position
Jul 21, 2010I'm trying to set a new cursor position but I get this error:
A call to PInvoke function 'mon! WindowsApplication1.Form1::SetCursorPos' has unbalanced the stack. This is likely because the managed PInvoke signature does not match the unmanaged target signature. Check that the calling convention and parameters of the PInvoke signature match the target unmanaged signature.
Here is the code:
Declare Function SetCursorPos Lib "user32" _
(ByVal x As Long, ByVal y As Long) As Long
SetCursorPos(457, 603)
It used to work when I used VS 08 but now I use VS 10 and this problem has started to appear.
