I have 2 trackbars (scrolling things) and i have a song playing in a media also but what i want is it to get the left speaker volume in 1 trackbar and the right speaker volume current in another, so when the song is playin it will adjust automatically and display the current left & right speaker volume (example: when the media goes louder the trackbar will probably increase) ive seen it in many programs.
View 6 RepliesI am trying to write a countdown timer I finally succeeded with MSDN. I get to work whatever I wanted, but this drives me nuts: How can I read and set the volume control? I want, once my timer is run down to zero, read out the current system setting, then play a system sound using
Media.SystemSounds.Exclamation.Play()
Over time I like to ramp up the volume to 80% or until one clicks the Alarm off button (then stop the timer, no sound, and reset volume).
I am working on a little project for my phone creating some sort of remote to turn up/down my system volume via wifi. The phone will send data to a text field on the website lets say such as "vol up" and the vb app sitting on the computer will be constantly reading this text field for key words like "vol up", "vol down". when it see's a recognized command it reacts by turning the volume up and so on. And one more thing: Is it possible to have a vb app that uses http? E.g., sits on port 80 itself and can be accessed via local ip.

I created a SQL application that synchronises with a SQLCE database when loaded. Works fine on my Dev machine but produces the following error on user machines:
System.IO.FileNotFoundException: Could not load file or assembly 'Microsoft.Synchronization.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91' or one of its dependencies. The system cannot find the file specified.
File name: 'Microsoft.Synchronization.Data, Version=1.0.0.0, Culture=neutral, PublicKeyToken=89845dcd8080cc91'
In my attempts to fix, I have:
1) Reinstalled SQL Compact Editon 3.5 on the client machines
2) Reinstalled .NET Framework 3.5
3) Installed Microsoft Sync Framework 1.0 (which puts the 'missing' DLL onto the machines).
This still fails with the same error.

View 1 RepliesDoes 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.
I 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?

How can I control the Computers volume inside visual basic? (like you have the speaker icon and when you click on it Volume scroll thing) at the bottom left of Windows, but I want it in my program. I am running Windows 7 (if that makes any difference
View 1 RepliesI'm trying to make a utility that will fade out the system volume (for when I fall asleep listening to my music). In XP and prior, controlling the system audio was very simple, however, in Vista and 7, I can't figure out how to do it. Because in Windows 7 each application has it's own volume control, lowering the volume doesn't affect the system overall - only the current app. Can anyone point me to a resource how to do this? Every forum posting that I've found on this topic is about XP, and doesn't work under newer versions of Windows.

View 3 RepliesWe have data feed, a file with index values and dates (like the S&P 500, for instance). The dates are represented as YYYYMMDD. The Date.Parse() method doesn't understand this format, of course.I wrote a simple static method on a class to parse this, not a big deal, but it irritates the engineer in me that I can't figure out how to get the IFormatProvider functionality to work. All the examples deal with the FORMATTING step, not the PARSING step.So basically, I want to be able to say:
Dim d as DateTime = Date.Parse("20110522", New CustomFormatter())
and get the correct date value out of the Parse method.
Having implemented the IFormatProvider method on CustomFormatter, the GetFormat() method gets called with a System.Type of DateTimeFormatInfo, but I honestly have no idea what to do from there since all the example deal with formatting, not parsing. It doesn't matter if I return an object (self) or null I simply get "String was not recognized as a valid DateTime."

I have a device (a few actually) that connects via USB to a PC. From here it acts like a basic storage device using FAT32 as the file system. The other thing is that it won't accept drive names (C:, E:, G: etc) to it so instead you need to use its Volume GUID to connect. I have retrieved this painlessley through MountVol.exe but thats where the difficulties ended.I am not trying to access the file system through VB.NET/C#.net (either will be fine - fluent in both ;) ). In Windows Explorer I can easily visit '\?Volume{71E4C2C7-E511-4B2A-BF5C-569B2B25784E}apic' to access the device and its files. I can also use CMD and the Dir command to go through the files. Just .NET cant seem to cope. I understand the GUID changes on each PC and I am OK with this as I can use MountVol to get the GUID and run the console app with command arguments as it will always be a human initiating the command.
I have tried manually entering the path via Console.ReadKeys but this also fails to even see the directory above and any of the files inside one being 'dev' without an extention. I can use System.IO operations without extensions on "normal" drives (ie those
with letters) so I know it's not the extension causing problems. I did a Try/Catch with a StreamReader pointing to the file to see what was spurted out:
System.ArgumentException: Illegal characters in path.

I am working on a VB NET project and had the strangest thing happen.I created a class file(just like a dozen or so I have already created). I wrote in the code to access it. The autocomplete found the class, filled it in and colored it blue, just as it should.But, when I run the app, I get a type is undefined error.
There is nothing in the class yet. And there is really no code to post..it is as straight forward as I described.I tried restarting VS; Deleting and recreating the class; Deleting the class and creating a new one with a different name.
Is there something in the VB NET configuration I can check to see if it is not being added somewhere?
I found the problem. I have 2 projects in one solution. They both share some classes that were trying to use my new classes. When I hit F5, both projects are compiled, and since I hadn't shared the classes with the second project, it errored.
So, now my question is changed; How do I specify to only build the specified Startup Project when debugging?
