SCROLLINFO scrollinfo;  
GetScrollInfo(SB_HORZ,&scrollinfo,SIF_ALL);  
switch (nSBCode)  
{  
case SB_LEFT:  
ScrollWindow((scrollinfo.nPos-scrollinfo.nMin)*1,0);  
scrollinfo.nPos = scrollinfo.nMin;  
SetScrollInfo(SB_HORZ,&scrollinfo,SIF_ALL);  
break;  
case SB_RIGHT:  
ScrollWindow((scrollinfo.nPos-scrollinfo.nMax)*1,0);  
scrollinfo.nPos = scrollinfo.nMax;  
SetScrollInfo(SB_HORZ,&scrollinfo,SIF_ALL);  
break;  
case SB_LINELEFT:  
scrollinfo.nPos -= 1;  
if (scrollinfo.nPos<scrollinfo.nMin){

一般在对话框那个函数里设置呀
引用:引用:用自己写的继承cwnd的滚动条 咋设置呢
引用:滚动条消息？你去滚动才会触发啊。对话框当然可以有滚动条，CWnd::SetScrollInfo设置好就行。自己写自己设置，谁知道你怎么写的呀。

OnInitDialog初始化；任何需要的地方都可以调整。
