高手请进:把纸张定义为三分之一高的241纸,当报表打印时,为什么会竖着打?

goj2000 2003-12-13 11:10:46
把纸张定义为三分之一高的241纸,当报表打印时,为什么会竖着打?
比如:我用自定义纸张:10×11寸的纸打印时,报表是横向打印的,这是我希望的格式。
但当我把纸张定义为10×(11/3)即高度为标准的三分之一时,预览是横向,但打印出来却是竖向的。为什么?我是用VB的自身的报表工具做的。
我要加60分哟。

最后,建议老兄以后做报表最好转到crystal report 或 active report!

我现在就是用crystal report做报表! 而且,VB6自带的那个报表以后就从这个世界上消失了!
据听说,MS以后要推出一款非常值得期待的报表设计器!


祝:老兄好运,能解决当前问题!

对呀,用水晶报表就好多了!
不好意思,因为CSDN最多只让连续发三次帖子,所以还没有说具体的调用方法:


老兄:不要怕麻烦,很简单的:你只要把以上两个类添加到你的工程中就OK了,也不要管看懂,还是看不懂!!说实话,我到现在还不完全懂呢!!!!(哈哈!)

接下来,就是我的调用打印的一个按钮下的单击事件:

(注意:还要加上一点:你必须在你的打印窗体上添加上一个listBox控件,这用来,列出你的机器 上的所有按装的打印机。)

谢谢两位高手。如果改用水晶报表等工具,是否就不存在这种问题了呢?

老兄,我也做过套打的程序,也是自定义纸张类型。当时用的也是MS VB6自带的那个变态的报表设计器,只要你的纸张类型不是标准的纸张(A4)类型,那打印进就是像你所说的竖向打印。

我是用一些类,来实现打印的,且改变成了横向打印。

源码如下:
1>orient.bas

'------COMMENTS

'For use on NT:
' When adding a printer icon to the printer folder (when you double-
' click on "Add Printer"), it is important to choose to save printer
' settings on "My Computer" rather than on "Network Printer Server".
' If "Network Printer Server" is used, then SetPrinter will fail
' unless the user has privileges on the network printer server to
' change the network server's global settings - in which case ALL
' users of that printer are affected. Whereas, when "My Computer"
' is selected, the user only needs privileges on the local NT machine
' and no one else is affected.

'HP LaserJet 5si
' As of 3/2/98, The HP LaserJet 5si printer driver does not work
' properly with the SetPrinter API call. After using this code,
' the 5si properties in the Printer folder are unaffected.
' 3/2/98 -- The current workaround is to use the HP 4si driver.


'------CONSTANTS

'Constants used in the DevMode structure
Private Const CCHDEVICENAME = 32
Private Const CCHFORMNAME = 32

'Constants for NT security
Private Const STANDARD_RIGHTS_REQUIRED = &HF0000
Private Const PRINTER_ACCESS_ADMINISTER = &H4
Private Const PRINTER_ACCESS_USE = &H8
Private Const PRINTER_ALL_ACCESS = (STANDARD_RIGHTS_REQUIRED Or PRINTER_ACCESS_ADMINISTER Or PRINTER_ACCESS_USE)

'Constants used to make changes to the values contained in the DevMode
Private Const DM_MODIFY = 8
Private Const DM_IN_BUFFER = DM_MODIFY
Private Const DM_COPY = 2
Private Const DM_OUT_BUFFER = DM_COPY
Private Const DM_DUPLEX = &H1000&
Public Const DMDUP_SIMPLEX = 1
Private Const DMDUP_VERTICAL = 2
Private Const DMDUP_HORIZONTAL = 3
Private Const DM_ORIENTATION = &H1&


'------USER DEFINED TYPES

'Note that this only represents the PUBLIC portion of the DevMode.
' The full DevMode also contains a variable length PRIVATE section
' which varies in length and content between printer drivers.

' Always combine it into a FULL DevMode structure and then send the
