关于SB_THUMBTRACK 来者有分

Question

我想通过消息控制滚动条的位置this->SendMessage (WM_VSCROLL,SB_THUMBTRACK, 10);这样可以么谢谢

Answer 1

SendMessage(WM_VSCROLL, MAKEWPARAM(10, SB_THUMBTRACK),hwndscrollbar);

Answer 2

tree和listbox
用***.SendMessage(WM_VSCROLL,MAKELONG(SB_THUMBTRACK,40),NULL);这样的方法都可以。
对于ListCtrl好象是只能用他自己的Scroll方法

Answer 3

i_Position += 2;
GetDlgItem(IDC_SLIDER1)->SendMessage(WM_VSCROLL,MAKEWPARAM(SB_THUMBTRACK,i_Position),NULL);必须先初始化

Answer 4

i_Position += 2;
GetDlgItem(IDC_SCROLLBAR1)->SendMessage(WM_VSCROLL,MAKEWPARAM(SB_THUMBTRACK,i_Position),NULL);
