打印预览对话框和Mdi表单

问题描述

亲爱的团队，

我在printpreview对话框中有一个printdocument页面，这是vb.net中的mdi子窗体。
当我关闭mdiform（mdiparent）时
每次调用printdocuments beginprint / printpage事件时，每次调用mdi close方法时，我们都可以停止这种行为。



在printdocument构造函数中我通过了菜单上的Mdi_Form

单击mdi表单我调用构造函数和构造函数代码如下

Dim PrintDialog1作为新的PrintPreviewDialog

PrintDialog1.Document = PrintDocument'PrintDialog与PrintDocument相关联。

PrintDialog1.mdiparent = mdiform

PrintDialog1.Show（）





和打印所需的所有代码都在

Print_Doc ---- Begin_print和Print_Page事件



工作正常，但当我关闭mdi表单时，它再次只调用这些事件

Print_Doc ---- Begin_print和Print_Page活动

谢谢

Dear Team,
I have a printdocument page in printpreview dialog and which is a mdi child form in vb.net.
when i close the mdiform(mdiparent) every time it is calling the printdocuments beginprint/printpage event again and every time the mdi close method is called,can we stop doing this behavior.

in printdocument constructor i passed the Mdi_Form
on menu click in mdi form i called the constructor and constructor code is below
Dim PrintDialog1 as new PrintPreviewDialog
PrintDialog1.Document = PrintDocument 'PrintDialog associate with PrintDocument.
PrintDialog1.mdiparent=mdiform
PrintDialog1.Show()


and all the required codes for printing is in
Print_Doc----Begin_print and Print_Page event

its working fine but when i closed the mdi form it again call only these events
Print_Doc----Begin_print and Print_Page event
Thanks
