I have been surfing the net all night to try and just learn how to do what I think should be a simple thing! How do I in vb.net when I press a button make it so that the windows volume changes to 50%? Is this that hard to do? Why cant it be like "windows.volume = 50" or something?

View 4 RepliesI'm attempting to use waveOutSetVolume from coredll.dll to gradually increase the audio volume from silent (or near silent) to maximum.
Most of the code examples I'm finding show some predefined set points for Off, Low, Normal, Medium, High, and Very High like this:
Public Enum Volumes As Integer
OFF = 0
LOW = 858993459
[Code]....
OK, and here's some API documentation which doesn't make a lot of sense to me in this particular context. What is low-order word and high-order word and how can they both exist in a single value?
· dwVolume New volume setting. The low-order word contains the left-channel volume setting, and the high-order word contains the right-channel setting. A value of 0xFFFF represents full volume, and a value of 0x0000 is silence. If a device does not support both left and right volume control, the low-order word of dwVolume specifies the volume level, and the high-order word is ignored.
Using 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?

View 1 RepliesSo I'm a bit new to the whole Vista/7 audio setup. My understanding is that a new "mixer" is created for each application.

View 9 RepliesBasically, I have developed one form which is generic and display different views. On that form I have used Close button. Alphabet E is short-cut for closing the form (i.e. mnemonic functionality).During execution of the form, when I press "E" on that form, my form closes automatically. As per my understanding mnemonic works with Alt control only. I am not sure if I am missing any properties that should be set so that this problem is resolved.
View 1 RepliesI have recorded this macro that attaches to a process (nunit.exe) for me. Now I'd like to press a button (named "Run") on the window of the process I am attaching to, but how? I have recorded this macro:

I am using nunit 2.5.7 and for attaching and debugging to work you need to attach to the nunit agent and press run on the nunit gui, for more recent versions of nunit you can attach to the nunit gui.the above script enables nunit debugging from the Visual Studio IDE with just visual Studio and the nunit binaries. all you need to do is set up nunit as an external tool (with the current project as a parameter), create a custom toolbar, and add a button to that toolbar that uses the above script. this will start nunit, attach to it, start running the tests, and break at your breakpoint.
one more thing: in the nunit gui disable "Save Visual state of each Project" in Tools -> Settings -> Tree Display or the nunit gui will remember the last run test, which is a pain if that's not the one you wanted to debug.
