1、對(duì)話框自帶滾動(dòng)條的使用一， 使用對(duì)話框窗口自帶的滾動(dòng)條，在屬性頁面中設(shè)置即可，如下二， OnInitDialog()函數(shù)中，添加如下滾動(dòng)條初始化語句SCROLLINFO vinfo;vinfo.cbSize =sizeof(vinfo);vinfo.fMask =SIF_ALL;vinfo.nPage =50;/滾動(dòng)塊自身的長(zhǎng)短，通常有如下關(guān)系：其長(zhǎng)度/滾動(dòng)條長(zhǎng)度（含兩個(gè)箭頭）=nPage/(nMax+2)， /另外nPage取值-1時(shí)，滾動(dòng)條會(huì)不見了。vinfo.nMax =600;/滾動(dòng)條所能滾動(dòng)的最大值vinfo.nMin=0;/滾動(dòng)條所能滾動(dòng)的最小值vinfo.nTrackPos =0

2、;SetScrollInfo(SB_VERT,&vinfo);/即使上述步驟一不做，使用此條語句也可以顯示滾動(dòng)條三， 添加相應(yīng)的WM_VSCROLL函數(shù)void CMy1d0Dlg:OnVScroll(UINT nSBCode, UINT nPos, CScrollBar* pScrollBar) / TODO: Add your message handler code here and/or call defaultSCROLLINFO scrollinfo;GetScrollInfo(SB_VERT,&scrollinfo,SIF_ALL); switch (nSBCod
