Audio Causing Imagery Movement To Stagger?
May 28, 2009
i'm working on something like a slot machine reel spinning with images on it.I've constructed a long image, dynamically, and have that image now stored in memory.I'm able to simulate that image "spinning" nicely by moving it vertically within a panel, and having it repeat. This is taking place in a separate "timer" function.
This seems to move quite smoothly until (on some machines) I output a bit of audio. I'm using the format:
My.Computer.Audio.Play(SoundFile3, AudioPlayMode.Background)
The SoundFile3 is simply a physical path to an audio file.When I call this function for the audio, and when it's not a powerhorse pc, it disrupts the spinning, and the spinning acts a little crazy/random.
Is there a more efficient approach for audio, like storing it in memory ahead of time?I'm tempted to go the multi-thrad approach to try to get the option of multiple sounds at the same time, but I don't know ifthat will help or hurt the situation. And I don't know how that's done.

I'm working on a windows forms application and would like to incorporate a feature that would allow me to pull the video stream from a networked DVR source. I have an existing desktop program that I may be able to use to snoop out some of the protocols used, but I have absolutely no idea where to look for a library or api to actually display the video.
Has anyone successfully done this? (Connected to a remote DVR, played realtime video in their own application)

I just want to ask or I need some idea on how to convert wav files to mp3 and compressed the file to make the size smaller. I've search on the internet and find vorbis.dll as a reference object and lame.exe for converter. With regards to the audio compression, i downloaded monkey's audio software but doesnt have an idea on how to incorporate it.

I have a database application developed around Access with VBA,I have used the Speech SDK and developed an application that in conjunction with MSCOMM 6.0 library calls into a remote IVR system.It sends in the credentials and queries information in response to that IVR's verbal requests. All seems successfull except for one problem;I'm using a shared SR engine and its using the system microphone as its audio input, this in turn gets the sound from the speakers which are routed to the telephone line through the modem. Of course this has a number of disadvantages - noise added to the sound from the environment and sound quality degredation as well as speaker volume dependency.
I would like the SR engine to take its audio input from the modem in paralell with the sound that goes to the speakers (so we can listen in to the call as well). This means that I must route the system audio output to the SR engine audio input. It seems that I must use an InProc SR instance - however in VBA that type is not recognized - since the shared SR uses the microphone as input by default. there is some statement to the effect that it is difficult in Microsoft's Help file. I'm unable to set the SR audio input to the modem output stream in VBA.As needed I can accomplish the C++ interface using an ActiveX object or a DLL to expose the missing API to VBA?

Using VB on a graphics screen I want to have the cursor move on a grid as opposed to every pixel. I believe I must hide the cursor and then draw it myself over the background, but I do not understand how to do this.

how to get VB to detect mouse movement, clicks and keyboard presses. I am creating a screensaver program that does not intergrate with the windows screensaver.
The reason I am doing this is because I am trying to invent a screensaver that people can use their custome pictures to see with password protection for their PC when the screensaver facility has been disabled on a domain.

When I plug in the USB joystick, I'll have to go to the control panel and select game controllers. I click on the properties and a pop-up is displayed. On the top left hand corner of it, there's this small square 'picture' with a plus sign at the middle indicating the joysticks' movement. As I moved up, the sign moves up as well and as I move down it does too. It depicts the movements of the joystick in use.
I was wondering how to code the exact same thing as I'm planning to place the square thingy in a 'question' image which will change after every submitted answer of the image using the joystick.

I have a picturebox (X=1200,Y=800) and there is an area in the picturebox starting at (X=32,Y=32 and is 256x256 in size). I want to keep the mouse pointer in that area for awhile.
Is there a command in vb that lets you do this? If not, can you restrict the mouse to one control?

I've made a program where a picture of a bee buzzes around the form in random movements (using random number generator code) and have put it in a while loop so that whilst the bee is visible on the form (hasn't flown off the sides) it moves randomly:
While (picBee.Top > 0 And picBee.Top < 725) And (picBee.Left > 0 And Timer1.Enabled = True)
Application.DoEvents()
For i = 1 To 3000000
Next
picBee.Top = picBee.Top - 2 + 4 * Rnd()
picBee.Left = picBee.Left - 2 + 4 * Rnd()
End While
So far the bee does stop moving when it meets one of the four edges of the form but I need to code it so when the be reaches the edges and stops a message box appears declaring the game over.

Ok, so I'm making a simple breakout game, using picture boxes as I didn't want to bother installing picture boxes.Every movement works perfectly fine; the pad moves correctly, the ball bounces right. Except when I move the pad while the ball is moving.If I move the pad while the ball is moving, the ball moves at the same speed as the pad, which is 10 times the speed of the ball.Well here's the movement code.
Code:
Public Sub Movement(ByVal Movement As String) ' Handles movement
If Not IsPlaying Then Exit Sub

if its possible to have mouse events like mouse movements, mouse clicks and so on in a specific window only. I'm not sure if you understand this so ill give you an example.
Okay lets say i want this program to only click within a window like Firefox or windows media player only. So that means if i minimize the window it will still click inside that window while its minimized, and i could continue doing other things while its clicking inside that window.

So, I am just trying to get the snake to move after it collides with the picture box. Right now, the snake is moved by using the arrow keys. However, once it collides with "the food", it won't move.

The code I have is meant to be used during possible rapid mouse movement by the user. It is supposed to get the current location (works), move to specified location (works), mouse down(works), mouse up (works), then return the mouse to the old position. I added the delay because it seemed that it was having trouble registering the click if done too quickly. The problem I am having is that if the user is moving their mouse during the time the code is activated, their movement can throw the location of the mouse down or mouse up events off even with the added check routine I added.
'Get current mouse position
Dim MousePosX As Integer = Windows.Forms.Cursor.Position.X
Dim MousePosY As Integer = Windows.Forms.Cursor.Position.Y
Q = True
'Move mouse to Q Location and click

In an attempt to try and make a chess AI I started working on a chess project. The AI will basically be in a class that implements my AI interface. To provide flexibility this can be used for a human player or a computer AI. In any case the problem I'm having is calculating the valid moves that a single piece can have.I calculate on what blocks the piece would be able to move if the board was totally empty. (this is represented by a array of point)Then I get a list of piece locations of the same team and Except that from said list.(since pieces can move through other pieces of its team)Now here is the tricky bit obviously taking an enemy piece is a legal move I can't just subtract enemy piece positions. Lets say there are 2 black pawns and a white rook in the same column. The rook would be able to take the first black pawn but not the second one because the first pawn is in it's way. In reality there would never be such an easy example so I need a way to only include the enemy positions "In the line of sight" of the piece's moves i'm calculating.

how to create a Auto repeated Mouse movement.I wanna create a Form, with a button "start 01" and "start 02",so if I click on "start 01" button, and i open my other applications, and once I hit the F1 button (on my keyboard) the mouse will auto move from point A to B, and it will keep on repeat until I hit the F12 button, then it will stop auto moving.and if I click on the "start 02" button, and II open my other applications, and once I hit F1 button (on my keyboard) the mouse will now move from D to E, and it will keep on repeating it until I hit the F12 button, then it will stop auto moving.
