在MFC中，如何读取外部的位图文件，让它显示在图片控件(Picture Control)中？
告诉你一个最简单的方法,你一定可以的,弄好了记得给我加分.
1.在你的对话框添一个按钮和一个图片控件(Picture Control).
2.添加一个类,我这里上传不了,只能将.h和.cpp复制过来,你再将拷贝到txt里,改一下扩展名就可以了。
这是Picture.h

先包含头文件#include "Picture.h"
再定义
CPicture m_Pic;
4.给按钮的函数里写上:(注意,这个IDC_SHOWPIC)是你那个显示控件的ID号.
CRect rect;
GetDlgItem(IDC_SHOWPIC)-GetWindowRect(rect);
ScreenToClient(rect);
CFile f;
CString FilePathName;
CFileException e;
CFileDialog dlg(TRUE,NULL,NULL,0,_T("All Files (*.*)|*.*|BMP (*.bmp)|*.bmp|DIB (*.dib)|*.dib|EMF (*.emf)|*.emf|GIF (*.gif)|*.gif|ICO (*.ico)|*.ico|JPG (*.jpg)|*.jpg|WMF (*.wmf)|*.wmf||"),NULL);

}
Mpos刷卡和移动pos刷卡有什么区别？哪种好用？
在不考虑手续费费率的情况下，这两类POS机相比较，可谓各有优缺点：
1、在体积方面，手机POS机比便携POS机更小；
2、在刷卡方面，手机POS机感应条小，刷卡的识别率不及便携POS机；
3、在便民方面，手机POS机因为有手机客户端应用，支持转账、还信用卡、充手机话费、帐户余额查询等功能，而移动POS则没有这些功能。
4、费用方面Mpos比传统pos和移动pos费用要低。
5、签购方面：移动pos有纸质签购单，mpos没有纸质签购单,不过在一次金融展会上看到visa使用了济强的vmp02来解决了纸质签购单打印的问题，相信以后也会有纸质签购单。
