VC中如何滚动条宽度

[w465153362w]

创建了一个WS_VSCROLL风格的窗口，如何获得窗口上的垂直滚动条宽度呢？

去查GetSystemMetrics
可以参考这个

SCROLLBARINFO sbinfo;
memset(&sbinfo, 0, sizeof(SCROLLBARINFO));
if (!SendMessage(hwnd, SBM_GETSCROLLBARINFO, 0,&sbinfo))
return 0;
int left = sbinfo.left;
int right = sbinfo.right;
int top = sbinfo.top;
int bottom = sbinfo.bottom;

SM_CXVSCROLL, SM_CYVSCROLL

int nWidht = GetSystemMetrics(SM_CXVSCROLL);
int nHeight = GetSystemMetrics(SM_CYVSCROLL);
