pzone(见分眼红) 能不能详细解释一下
typedef struct tagDEVNAMES { // dvnm
WORD wDriverOffset;
WORD wDeviceOffset;
WORD wOutputOffset;
WORD wDefault;
// driver, device, and port name strings follow wDefault
} DEVNAMES;
各个变量的用途；
TangDL(^_^) ：修改Ini文件 ，怎么改，98中不能用程序实现吗？

以上为修改缺省打印机，修改属性API为GetPrinter/SetPrinter

函数由指定的设备名，获得DEVMODE 与DEVNAMES 所需要的内容，再由它们设置打印机,ok.

1.Call the Windows API functions GetProfileString and WriteProfileString to change the printer setting device= in the [windows] section of the WIN.INI file to one of the printers listed in the [devices] section.
For example, a WIN.INI file would contain the following settings to make an HP LaserJet the default printer:
[windows]
device=HP LaserJet IIISi PostScript,pscript,LPT1:
[devices]
Generic / Text Only=TTY,FILE:
HP LaserJet IIISi PostScript=pscript,LPT1:
2.Call the Windows API WriteProfileString function using all NULL pointer parameters to force Windows to reload the WIN.INI file into memory. (WIN.INI is normally cached in memory and not reloaded until you restart Windows.) Pass all parameters By Value as type Long with value 0.
3.Call the SendMessage API function with hWnd% parameter set to HWND_BROADCAST (&hffff) to broadcast a message to all pop-up windows currently loaded in the system. Setting the wMsg% parameter to WM_WININICHANGE notifies all top-level windows of a WIN.INI change, and WM_DEVMODECHANGE notifies them of a device-mode change.
