我想在vb.net中打印一个winform（作为收据）。 [英] i want to print a winform (as receipt ) in vb.net.

问题描述

我创建了一个winform作为打印收据的设计。但现在我想打印这个tablelayoutpanel，以便用户可以打印。我必须使用VB.net Visual studio 2005.



i得到以下链接



HTTP：//www.c- sharpcorner.com/UploadFile/rahul4_saxena/print-receipt-and-save-data-using-window-form-in-C-Sharp/



但它在c＃.net中，无法通过工具进行转换，因为它使用了一些互操作服务和dllimport。



请有人建议我采用正确的方法。
