MFC制作数码管动态库

MFC制作数码管动态库1．新建一个DLL工程打开VS2012,点击新建项目出现新建项目对话框,如下图所示；选择MFC MFCDLL;键入项目名称以及解决方案名称，可以不一样，选择存放位置，点击确定；进入MFC DLL向导，点击下一步；选择使用共享MFC DLL的规则DLL点击完成；这时候就生成了一个空的MFC DLL工程；2.添加用户程序点击解决方案资源管理器；右击头文件，添加--->新建项进入添加新项界面，选择头文件，输入头文件名，点击添加同样的方法在添加一个源文件；代码：CPP文件void OnDraw1(CDC *pDC,COLORREFcolor,intx,inty,floatch,intindx){CPen Pen(PS_SOLID, 1, color);//数码管外框画笔CPen *OldPen=pDC->SelectObject(&Pen);CRgnRgn;CPoint Point[7],Point1[7],Point2[7],Point3[7],Point4[7],Point5[7],Point6[7];Point[0]=CPoint(x,y);Point[1]=CPoint(x+(ch*16),y);Point[2]=CPoint(x+(ch*17),y+ch);Point[3]=CPoint(x+(ch*14),y+(ch*4));Point[4]=CPoint(x+(2*ch),y+(ch*4));Point[5]=CPoint(x-ch,y+ch);Point[6]=CPoint(x,y);Point1[0]=CPoint(x-2*ch,y+2*ch);Point1[1]=CPoint(x+ch,y+5*ch);Point1[2]=CPoint(x+ch,y+17*ch);Point1[3]=CPoint(x-2*ch,y+20*ch);Point1[4]=CPoint(x-3*ch,y+19*ch);Point1[5]=CPoint(x-3*ch,y+3*ch);Point1[6]=CPoint(x-2*ch,y+2*ch);Point2[0]=CPoint(x-2*ch+(ch*20),y+2*ch);Point2[1]=CPoint(x+ch+(ch*14),y+5*ch);Point2[2]=CPoint(x+ch+(ch*14),y+17*ch);Point2[3]=CPoint(x-2*ch+(ch*20),y+20*ch);Point2[4]=CPoint(x-3*ch+(ch*22),y+19*ch);Point2[5]=CPoint(x-3*ch+(ch*22),y+3*ch);Point2[6]=CPoint(x-2*ch+(ch*20),y+2*ch);Point3[0]=CPoint(x-2*ch,y+2*ch+19*ch);Point3[1]=CPoint(x+ch,y+5*ch+19*ch);Point3[2]=CPoint(x+ch,y+17*ch+19*ch);Point3[3]=CPoint(x-2*ch,y+20*ch+19*ch);Point3[4]=CPoint(x-3*ch,y+19*ch+19*ch);Point3[5]=CPoint(x-3*ch,y+3*ch+19*ch);Point3[6]=CPoint(x-2*ch,y+2*ch+19*ch);Point4[0]=CPoint(x-2*ch+(ch*20),y+2*ch+19*ch);Point4[1]=CPoint(x+ch+(ch*14),y+5*ch+19*ch);Point4[2]=CPoint(x+ch+(ch*14),y+17*ch+19*ch);Point4[3]=CPoint(x-2*ch+(ch*20),y+20*ch+19*ch);Point4[4]=CPoint(x-3*ch+(ch*22),y+19*ch+19*ch);Point4[5]=CPoint(x-3*ch+(ch*22),y+3*ch+19*ch);Point4[6]=CPoint(x-2*ch+(ch*20),y+2*ch+19*ch);Point5[0]=CPoint(x,y+41*ch);Point5[1]=CPoint(x+(ch*16),y+41*ch);Point5[2]=CPoint(x+(ch*17),y+ch+39*ch);Point5[3]=CPoint(x+(ch*14),y+(ch*4)+33*ch);
