CPrintingDialog是什么呀在打印中如何用呀

CPrintingDialog在viewprnt.cpp中，一般情况下用不到，除非你想定制打印过程中的状态显示。

我将CPrintDialog 改成CPrintingDialog dlgPrintStatus(this);
出现以下错误怎么解决呀
error C2065: 'CPrintingDialog' : undeclared identifier
: error C2146: syntax error : missing ';' before identifier 'dlgPrintStatus'
: error C2065: 'dlgPrintStatus' : undeclared identifier
: error C2228: left of '.SetDlgItemTextA' must have class/struct/union type

我就是想做个打印功能
可是总是出错
我将CPrintDialog 改成CPrintingDialog dlgPrintStatus(this);

想做个打印功能直接CPrintDialog 不就可以了嘛

我已经找到CPrintingDialog了
怎么用呀

不知道你为什么要“将CPrintDialog 改成CPrintingDialog”，编程序不是随心所欲的事情，要严谨。
