mfc编程小结.doc

1,mfc显示位图
if(!m_Dlgbar.Create(this,IDD_DIALOGBAR,CBRS_LEFT|CBRS_TOOLTIPS|CBRS_FLYBY,IDD_DIALOGBAR))
{
TRACE0("FailedtocreateDlgBar\n");
return-1;//failtocreate
}

voidCTestView::OnDraw(CDC*pDC)
{
CTestDoc*pDoc=GetDocument();
ASSERT_VALID(pDoc);
//TODO:adddrawcodefornativedatahere

//TODO:adddrawcodefornativedatahere
//在视图中显示一副图像
/*HBITMAPhBitmap=(HBITMAP)LoadImage(NULL,"F://testui//testui.bmp",IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);
//定义一个位图对象
CBitmapm_bitmap;
//将位图句柄与位图对象相连接
m_bitmap.Attach(hBitmap);
//位图信息结构
BITMAPbm;
//将位图数据存入位图结构
m_bitmap.GetBitmap(&bm);
//源
CDCdcImage;
dcImage.CreateCompatibleDC(pDC);
dcImage.SelectObject(&m_bitmap);
//画图
pDC->BitBlt(0,0,bm.bmWidth,bm.bmHeight,&dcImage,0,0,SRCCOPY);*/
}
2，坐标显示
CDC*pDC=GetDC();
CBrushbackbrush(RGB(205,205,180));
CBrush*pOldBrush=pDC->SelectObject(&backbrush);
CRectrect;
GetClientRect(rect);
pDC->PatBlt(rect.left,rect.top,rect.Width(),rect.Height(),PATCOPY);
pDC->SelectObject(pOldBrush);
//划XY坐标
CPenpen1(PS_SOLID,3,RGB(0,0,205));
CPenpen2(PS_SOLID,1,RGB(209,209,209));
CClientDCdc(this);
CPen*poldpen=dc.SelectObject(&pen1);
dc.MoveTo(40,20);
dc.LineTo(40,320); //o点
dc.MoveTo(40,320);
dc.LineTo(1040,320);

dc.MoveTo(40,360);
dc.LineTo(40,660); //o点
dc.MoveTo(40,660);
dc.LineTo(1040,660);

dc.SetBkColor(RGB(205,205,180));
dc.SetTextColor(RGB(0,0,0));
dc.SetTextAlign(TA_RIGHT);
dc.TextOut(30,310,"0");
dc.TextOut(30,650,"0");
//dc.TextOut(750,100,"压力显示（PA）");
//划分隔线和y分度
CStringstr;
poldpen=dc.SelectObject(&pen2);
for(inti=1;i<11;i++)
{
dc.MoveTo(40,320-i*30);
dc.LineTo(1040,320-i*30);
str.Format("%d",3*i);
dc.TextOut(30,320-10-i*30,str);

dc.MoveTo(40,660-i*30);
dc.LineTo(1040,660-i*30);
str.Format("%d",20*i);
dc.TextOut(30,660-10-i*30,str);
}
dc.SelectObject(poldpen);
3，CDialogBar显示
添加.h文件中
afx_msgvoidOnUpdateButton1(CCmdUI*pCmdUI);
在cpp中添加
ON_UPDATE_COMMAND_UI(IDC_BUTTON1,OnUpdateButton1)
voidCMainFrame::OnUpdateButton1(
