Hi Everyone,

How to get two input in a single Edit Box in VC++ in Visual Studio 2005
Its like getting an input from Edit Box(Divident) and second input(Divisor) in single Function.I have written a code which is not working i have tried many ways......

void CCalciDlg::OnBnClickedCbuttondiv()
{
    double a,b;
    resu.SetFocus();
    UpdateData(TRUE);
    a=num1;      //num1 is the Edit Box Resource
    resu.SetFocus();
    a=num;
    UpdateData(TRUE);
    resu.SetFocus();
    b=num1;
    num=a/b;
    
}

此代码将a和b都设为相同...

This Code Taking Both a and b as the same......

推荐答案

如果您需要从字符串(编辑框内容)中检索多个值，则(假设有可能，即存在值分隔符)，您必须对其进行解析(例如，参见 Parsing_expression_grammar [ ^ ].

If you need to retrieve multiple values from a string (the edit box content) then (supposing it is possible, i.e. there are value separators) you have to parse it (see, for instance Parsing_expression_grammar[^].
