activereport1.1如何更改纸张为横向和纸张的大小？

[j4sxw]

如题

我是说在VB中用代码设置。

[j4sxw]

哪位高手帮帮忙吧在下急晕了。
救人啊

[mndsoft]

注意：在win2k下不行，因为vb不支持自定义纸张大小！

Private Sub ActiveReport_Initialize()
'纸张高度
Me.Printer.PaperHeight = 15876
　　'纸张宽度
Me.Printer.PaperWidth = 11910
　　'纵向打印
Me.Printer.Orientation = ddOPortrait
End Sub

[ghphappy]

我是通过更改打印设置来改纸为横向,然后调整ACTIVEREPORT的TOPMARGIN,LEFTMARGIN...
这样能满足你的要求吗?

[j4sxw]

楼上兄弟那该怎么作？？

[ghphappy]

改打印设置就不用说了吧,后面的就是设置报表页边距.比如说一张纸能打印两份报表等.只能实现一些简单的要求了.如果能直接在报表中设置纸张大小和方向那就太好了.期待...

李洪根大哥在吗，帮帮忙。
