自定义打印页面的大小

[oklys]

在VC中怎么自定义打印机的页面的尺寸，最好有源码。谢谢！

这个问题我自己已经解决了，等我有时间把详细代码送上。

下面代码中从打印机中取得DEVMODE结构,然后你就可以做你想做的事情了
PRINTDLG pd;
ZeroMemory(&pd, sizeof(PRINTDLG));
AfxGetApp()->GetPrinterDeviceDefaults(&pd);

DEVMODE* pDV = (LPDEVMODE) ::GlobalLock(pd.hDevMode);
//Do something with the data...
GlobalUnlock(pd.hDevMode);

谢谢你的代码。

最近正在做一个打印的
