how do i control the volume level that the speakers output?
View 4 RepliesI have searched the web for code relating to changing the system volume, muting the system volume, and outputing the current level of the volume as an integer, using VB.NET.
All the code that I have found either doesn't work, or is very long.
I am making an application in VB.NET that allows a user to highlight some text in images of documents so that the highlights could be saved for future reference, but the original images would not be modified. I figured I can achieve it by creating a graphics out of an image file and allowing the user to draw on that graphics. The problem is - the graphics can not be created from indexed image files, which many of mine are. I am wondering: is it possible to create a transparent graphics surface above an image in a PictureBox control, so that the user could draw on that surface, but it would appear as if he is drawing directly on an image?
View 3 RepliesI'm drawing lines directly on a PictureBox. My problem is that the visible surface of the PictureBox is smaller than expected, considering the Height and a Width properties.For example, there is a PictureBox with Height = 200 and Width = 400 points.When I draw a point with coordinates of (0,0) it is clearly visible in the topleft corner. But when I draw a point with coordinates of (399,199), it's not visible. Actually, the bottommost and rightmost point in the Picturebox seems to have the coordinates of (397,197).
What's the reason behind this? Is the PictureBox always two points smaller, or is it size-dependent? Or a wrong setting?
studying GDI+ for drawing, there are many suggestions to expose the graphic surface for the paintbox control or a form using e.graphics in the paint event. Can graphics be exposed outside the paint for the picture box control?
In my old vb6 project that I am converting to vb.net 2010, I have several large routines located in a code module that draw lines, circles, etc on a picture box and it is desirable to keep these outside the paint event of the picture box so the same routines can be used to draw on more than one picture box.
In experimenting, I found I can create e.graphics from the picture box paint event and pass it by reference to a drawing routine and the drawing routine seems to work ok on initial experiments but it requires visiting the picture box paint event to get the drawing surface in the external sub.Is this apprach good programming practice or is there a better way to create the graphics surface of a picture box or form in subroutines outside the paint event?
Trying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?
View 2 RepliesI programmed with Bitblt in VB6 for about 5-6 years and now I switched to DirectX and VB.net. When I would make games in VB6, I would draw out the entire level into layers that were saved into memory on DC's.In DirectX however, I'm looking for the equivalent of that but cant find any examples around.I use a viewport system to follow the player along in the map, I copy only what is in the viewport over to the users screen.Image attached to better visualize what i mean.

View 5 RepliesI have a timer that bounces the ball around. It has 2 separate parts, one for bouncing off the wall and paddle, and one for hitting a block.It touches the block and the block is suppose to disappear, it then bounces away and should not bounce where the block is again because it is gone ,So basically the problem I'm having is, every time I add a line that tells it not to bounce off the block if it is not visible, it hits the top of the block (which is the side I'm testing) and seems to get stuck on a horizontal line and just bounces left and right.Here's my timer code.
vb
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'This top line below reads the last 'thespeedx/y' value and applies it to the new location information of the ball (which will be called shpcircle) This determines the direction, based on a constant speed[code].....
I guess thats what I need to do, Im trying to allow the user to right click on the top of my form, and my custom Context Menu Strip is displayed, not windows context menu strip. I guess somehow i would need to get the size and draw a rectangle on the non client area and see if the user has right clicked in that rectangle? if so how would I get the area of the non client area?

Why I don't see in Output window number 5 as output?
I'm just going to throw all my code in here in case there's something wrong with a piece of the code not in the "SelectName()" sub.
Module Module1
Dim selectednames As String = ""
Dim index As Short = 0
Dim inarray As Boolean = False
[code]....
Here's an image of what it does (I suppose you can see what went wrong)13 inputs, 3 outputs expected, only 1 output given.As from what I've figured out so far, it's doing the correct amount of loops etc. It's just as soon as it starts generating the "winner" for the 2nd game key it doesn't get a string value from namesarray.Also, why is
For x = 0 To totalnames - 1
Debug.Print("namesarray(" & x & ") = " & namesarray(x))
Next
not giving me a debug output?
How can I control the volume of only the sound coming from my program rather than the system sound with a track bar? If this isn't possible, how can I control the system volume with the track bar?Bgeo99
View 2 RepliesI've been looking online for almost two hours now, is it possible to set the volume level of a WAV file that a program you are designing plays? For example, you have a button on a form and when pressing button it plays sound but at a specific volume. I tried to find volume control tutorials but that seems to be a difficult one for coders.

Does anyone know how to get and set the system sound volume? I have tried every method I've found on the net and none of them work. I've tried the winmm.dll APIs with no luck. I've also tried waveOutGetVolume/waveOutSetVolume, which didn't work. I'm using Win 7, but need a solution that works on XP+.
Right now I use the VolumeUp keyboard event, but I need to be able to get the volume and set it to a specific level.

How can i adjust the volume through vb.net codesomething really simple (if only in C#, that'll work too)
View 2 RepliesI am using the AxWindowsMediaPlayer1 control to play MP3 sound files in my application.
I would like to lower and raise the volume (master) via keypress from my gamepad.
I already have the logic for that established, I just do not see any way to raise and lower the volume within the Windows Media Player control.
I'm making a media player that is using the Windows Media Player component and I have the visible property set to false. I'm going to make all of the controls but one I'm having trouble with is the scroll bar. with the scroll bar if you move up the track bar up a little it should increase the volume like the one on the component. The code that I though was AxWindowsMediaPlayer1.CtlControls. but there was nothing there that could be used to control the volume.
View 2 RepliesI have an application that plays wav and mp3 files using the Microsoft.DirectX.AudioVideoPlayback.Audio()function. It works fine, and I can easily set the volume level of the playback... within limits.
That limit is the system volume level. I can set the playback level for the mp3, but if the system volume is muted or set real low it may still play softly.
So how do I set the master volume level, including making sure it isn't muted?

I was creating a OS with vs 2008 and I made some easter eggs where if a key is pressed, it will show a full screen image of a RSoD. In the form's code, there is a code to mute all the volume I got in the internet:
Public Class Form6
Private Const APPCOMMAND_VOLUME_MUTE As Integer = &H80000
Private Const WM_APPCOMMAND As Integer = &H319
Declare Function SendMessageW Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As IntPtr, ByVal lParam As IntPtr) As IntPtr
[Code]...
And pressing the space key will bring it back to my desktop in the own-made OS.There are sounds I coded in it. But as the code above mutes the computer, I must unmute by my self. Can anyone give me the code to unmute??? Googling it up does not work.
