'你把下面的源码代码保存为Form1.frm，然后双击打开该文件，打印打印代码iot管理平台源码运行后按提示即可看到结果。源码
'呵呵，打印打印代码微信投票 源码够详细了，源码投票 微信 源码再不会我也没办法了。打印打印代码

vb.net如何实现打印DataGridView1里的内容，求源码
使用 PrintDocument 控件的打印打印代码 Print() 方法可以打印指定对象中的内容，参考代码如下：Private Sub Button1_Click(ByVal sender As System.Object,源码 ByVal e As System.EventArgs) Handles Button1.ClickPrintDocument1.Print()
End Sub
Private Sub PrintDocument1_PrintPage(ByVal sender As System.Object, ByVal e As System.Drawing.Printing.PrintPageEventArgs) Handles PrintDocument1.PrintPage
Dim bm As New Bitmap(Me.DataGridView1.Width, Me.DataGridView1.Height)
DataGridView1.DrawToBitmap(bm, New Rectangle(0, 0, Me.DataGridView1.Width, Me.DataGridView1.Height))
e.Graphics.DrawImage(bm, 0, 0)
End Sub
