Environment: VC6
Introduction
I love how the volume control of the RealOne player looks, so I decided to include it into my own applications. Because someone else may be interested in using it, here it is!
Note that this code only obtains a value, and does not affect the current audio configuration.
Usage
To use this class, you only have to create the control using the Dialog Editor as an slide bar (and select the desired horizontal/vertical orientation).
Then, using the ClassWizard, link the resource to a CSlideBarCtrl variable. Finally, change the type of this variable (which is in the dialog class definition) from CSlideBarCtrl to CVolumeBar (do not forget the #include!).
To set the volume (the range is 0-100), use the function:
void SetVolume(int volume)
And to get the current volume value, use:
int GetVolume()
Additionally, you can change the background color and the bar color by modifying the public attributes bkColor and barColor.
Future Improvements
The 3D effect on the “thumb” is not yet implemented, and the control would look nicer with it.
