如何使用 PRINTDLGA 中的 hDevMode

how to use hDevMode from PRINTDLGA

如何将HGLOBAL转为DEVMODE?我这样试过:

PRINTDLG pd;
pd.hDevMode = NULL;
if(PrintDlg(&pd)){
    DEVMODE* test=(DEVMODE*)pd.hDevMode;

根据 PRINTDLGA 文档:

hDevMode

Type: HGLOBAL

A handle to a movable global memory object that contains a DEVMODE structure.

所以,使用GlobalLock()访问DEVMODE,例如:

PRINTDLG pd = {};
pd.lStructSize = sizeof(pd);
...

if (PrintDlg(&pd)){
    DEVMODE* test = (DEVMODE*) GlobalLock(pd.hDevMode);
    // use test as needed...
    GlobalUnlock(pd.hDevMode);
    GlobalFree(pd.hDevMode);
}
