visual c++ - How to specify negative range for slider control? -


i developing mfc based sdi vc++ application. in application need specify negative range value slider control. minimum range slider -40 , maximum range 255. tried using setrange function. not working. how can set range in slider?please help..

my code slider follows: slider declared 

csliderctrl m_ctrlectslider;

oninitialupdate function contains

m_ctrlectslider.setrangemin(-40); int ivalmin = m_ctrlectslider.getrangemin(); m_ctrlectslider.setrangemax(255); int ivalmax = m_ctrlectslider.getrangemax();  m_ctrlectslider.setpos(0); setdlgitemint( idc_ect_value, m_ctrlectslider.getpos(), false); setdlgitemint( idc_min_ect, ivalmin, false); setdlgitemint( idc_max_ect, ivalmax, false);

onbnclickedset function contains

int nmin = getdlgitemint(idc_min_ect, 0, false); int nmax = getdlgitemint(idc_max_ect, 0, false);  m_ctrlectslider.setrange(nmin, nmax); m_ctrlectslider.setpos(nmin);  int pos = m_ctrlectslider.getpos(); setdlgitemint(idc_ect_value, m_ctrlectslider.getpos(), false);       m_ctrlectslider.redrawwindow();

here problem value returned during debugg correct. when comes ui on running min value 429496 , not -40 in edit box..why so..i developing sdi application using cformview class..

thanks in advance.

your minimum value '-40'which signed integer , treating unsigned integer last parameter of 'setdlgitemint' , 'getdlgitemint' method 'false'. that's why getting wrong value in place of '-40'. use following code correct behavior.

//for setting value

setdlgitemint( idc_ect_value, m_ctrlectslider.getpos(), true);

setdlgitemint( idc_min_ect, ivalmin, true);

setdlgitemint( idc_max_ect, ivalmax, true);

// getting value use follows

int nmin = getdlgitemint(idc_min_ect, 0, true);

int nmax = getdlgitemint(idc_max_ect, 0, true);
