在编程中，DDX_Text()和DDX_Control()这两个函数在数据绑定和控件操作中扮演着不同的角色。DDX_Text()的主要功能是将字符串变量与控件的文本属性关联起来。例如，在函数CView::DoDataExchange()中，它将变量m_strID的值与控件IDC_ID_VALUE的WindowText属性关联，以便在数据交换过程中同步更新。DDX_C...
DDX_TEXT()的作用可以理解为把字符串变量和控件的文本(WindowText)关联起来, DDX_Control()的作用可以理解为把变量和控件本身关联起来, DoDataExchange(pDX)就是处理所有变量与其关联控件交换数据的函数。 void CView::DoDataExchange(CDataExchange* pDX) { CFormView::DoDataExchange(pDX); DDX_Text(pDX, IDC_I...
