Question

C++ mfc做计算器 具体步骤 急！！！！

最好有源代码！！！

Answer 1

1.首先做计算器界面类,界面上要用0-9, +,-,*,/,=等(复杂点还可以做的和XP一样的科学计算器)
2.添加计算逻辑,每个按建点下后,在输出栏的显示

我这里有源代码,你如果要请提供邮箱

Hi我，或email:lijiuning(a)gmail.com 我给你发
下面是部分源代码：

void CCalDlg::OnButton0()
{
// TODO: Add your control notification handler code here
if(m_Mark==0)
{
m_StrBegin=m_StrBegin+"0";
m_DspEdit.OnDisplay(m_StrBegin);
}
else
{
m_StrEnd=m_StrEnd+"0";
m_IsCheckPoint=0;
m_DspEdit.OnDisplay(m_StrEnd);
}
}

void CCalDlg::OnButton1()
{
// TODO: Add your control notification handler code here
if(m_Mark==0)
{
m_StrBegin=m_StrBegin+"1";
m_DspEdit.OnDisplay(m_StrBegin);
}
else
{
m_StrEnd=m_StrEnd+"1";
m_IsCheckPoint=0;
m_DspEdit.OnDisplay(m_StrEnd);
}
}
