我用VB.net自带的打印预览不能直接点打印按键打印的。
dataprinter.start = 0
dataprinter.pagenumber = 1
PrintPreviewDialog1.ShowDialog()
这样的打印不行，
要下面这样打印才行
dataprinter.start = 0
dataprinter.pagenumber = 1
PrintDocument1.Print()
这样打印的话就不能预览的。。很麻烦，有什么办法可以解决吗？
Public Class Form1
Inherits System.Windows.Forms.Form
#Region " Windows 窗体设计器生成的代码 "
Public Sub New()
MyBase.New()
该调用是 Windows 窗体设计器所必需的。
InitializeComponent()
在 InitializeComponent() 调用之后添加任何初始化
End Sub
窗体重写 dispose 以清理组件列表。
Protected Overloads Overrides Sub Dispose(ByVal disposing As Boolean)
If disposing Then
If Not (components Is Nothing) Then
components.Dispose()
End If
End If
MyBase.Dispose(disposing)
End Sub
Windows 窗体设计器所必需的
Private components As System.ComponentModel.IContainer
注意: 以下过程是 Windows 窗体设计器所必需的
可以使用 Windows 窗体设计器修改此过程。
不要使用代码编辑器修改它。
