Recently unemployed at home, I have nothing to do, so I usually work, I have been accumulated when I study, I have made Demo, send it to everyone. First give everyone a rotating button control, just like CD Player ~~
Sample code: http://61.133.87.165/bbs/attachment.php? S = & postid = 216360
In addition, I have a lot of categories here, I have written, translated, and so on. Contact me with me in Ytweiwei@cnuninet.com. I hope everyone can learn together and progress!
The documentation of the class is as follows: (For everyone, you can find this document in Demo)

CroundsliderCtrl
CSLIDERCTRL

---- CROUNDSLIDERCTRL
This class is a derived class of CSLIDERCTRL. Expand the function of the circular slider control, and you can customize the color, pictures, settings in the control, etc. in the control.
Precautions when using this class:
1. Need to join the MEMDC.H file to the project, considering the universality of this class, if there is already in the original project, please do not repeat it.
2, add mouse pointer resources IDC_CURSOR
3. Some functions used in this class are from the Internet, and the copyright is still owned by it.
4, this class is created under VC6, due to certain particularities, compiling abnormal phenomena under VC.NET.
Instructions:
1. Add slider controls in the dialog and change to the size you want.
2, associated with control variables with controls in ClassWizard (such as M_RSCMYSLIDER)
3. In OnInitDialog (), you can call set setRange (), setpos () and other functions as needed to set up the initialization control.
When the control pointer is sliding, it sends a WM_Scroll message, so you can get the current location of the slider in your dialog. such as:
Void Croundsliderctrldemodlg :: Onhscroll (uint nsbcode, uint npos, cscrollbar * pscrollbar)
{
IF (pscrollbar-> getdlgctrlid () == IDC_SLIDER)
{
Trace ("WM_HSCROLL BY CROUNDSLIDERCTRL RECEIVED. NPOS:% LD? NSBCODE:% LD / N", NPOS, NSBCODE
}
CDIALOG :: OnhScroll (NSBCode, NPOS, Pscrollbar);
}
You can also overload the ONFORMATTEXT function in the derived class from the define the text displayed in the control, such as:
CString cfrequerncectrl :: ONFORMATTEXT (Const Cstring & StRTEXT)
{
CString strformattedtext;
StrformattedText.Format ("%. 1FMHz", 87.5 getpos () / 360.0 * 20.6);
Return strformattedText;
}
