vb.net如何实现打印DataGridView1里的小程序源码更换内容,求源码
使用 PrintDocument 控件的私人衣柜网站源码 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,django4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

求用vbnet 实现先进先出即队列得源代码
VB.Net中的队列类在System.Collections.Generic命名空间中,名字叫Queue,macd买入系统源码是热门短剧网站源码一个泛型类。
实例化该类:
Dim myQueue As Queue<Int>
myQueue = new Queue<Int>();
然后可以通过Queue中的Enqueue和Dequeue函数进行入队出队操作:
With myQueue
.Enqueue(1)
.Enqueue(2)
.Enqueue(3)
.Enqueue(4)
.Enqueue(5)
End With
For i = 0 To 5 Step 1
Console.WriteLine(myQueue.Dequeue())
Next i
显示结果:
1
2
3
4
5
