IE中用VBScript不提示直接打印的代码
首先在HTML 页面中加入WebBrowser 的Object:
OBJECT classid="CLSID:8856F961-340A-11D0-A96B-00C04FD705A2" height=0 id=wb name=wb width=0>/OBJECT>
之后,使用如下代码进行打印:
script language="VBScript">
sub printvb()
wb.execwb 6,2,3
End Sub
/script>
关键代码 wb.execwb 6,2,3 可以在 VBScript 方式下实际无需提示的直接打印,但奇怪的是用同样的参数,在 Javascript 方式下IE 依然会弹出打印对话窗口,也许是因为VBScript 是Microsoft 开发的专用于 IE 的吧,而 Javascript 毕竟是外人:)
另找到一个较全面的例子,如下:
6=OLECMDID_PRINT
2=OLECMDEXECOPT_DONTPROMPTUSER,
2+1=PRINT_WAITFORCOMPLETION + PRINT_DONTBOTHERUSER
WB.ExecWB 6, 2, 3, 0

OLECMDID_PRINT = 6

OLECMDEXECOPT_PROMPTUSER = 1
OLECMDEXECOPT_DONTPROMPTUSER = 2

WB.ExecWB x, y, z, 0
