网上下的VB.NET截屏程序,试过好用,哪位大侠给详细解释一下!另外,怎么把截图加载到Picturebox里?
VB.NT用的是触发事件,一按就会触发,要不你加个timer控件,延迟一秒
标题的问题:你先把图片保存,再加载
c#如何实现类似qq一样的截图功能?
按快捷键后,先把整个屏幕截下来,然后显示在form1上,form1是一个没有边框的窗体,之后最大化显示form1,开始鼠标拖坐标,截取坐标内的图片,保存,
补充:
4年前用vb写的:

vb模拟QQ 截图
下面的代码是我很欣赏的编程牛人CBM666的,你看下就应该能明白意思了,需要的haunted自己修改一下,我运行过了可以运行成功,不会截到其它窗体只是打印当前窗体
友情提示:你点下打印键的时候没有提示会直接打印出窗口内容来,没有确定取消的按钮的,当初我在公司试的时候随便贴了个很烂的图就给打出来了,还被人笑了。。。
'添加 Picture1 Picture2 各别放一张图片 窗体也可加图片, 只是测试用罢了.
,Text1 随便打一些内容,(只是测试用)
'再随便加一个Picture3 用来保存图片
'Command1 抓图存图 Command2 打印
'本代码是将窗体内所有的控件与窗体一起保存到Picture3再打印出来.
Option Explicit
Private Declare Sub keybd_event Lib "user32" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
Const theScreen = 0 '整个Screen
Const theForm = 1 '当前活动界面
Private Sub Form_Load()
Command1.Caption = "抓取窗体"
Command2.Caption = "打 印"
Picture3.Move Screen.Width
Picture3.AutoRedraw = True
Picture3.BorderStyle = 0
Me.AutoRedraw = False
Clipboard.Clear
End Sub
Private Sub Command1_Click()
Me.Refresh
Picture3.Picture = LoadPicture()
Picture3.Width = Me.Width
Picture3.Height = Me.Height
Call keybd_event(vbKeySnapshot, 1, 0, 0)
DoEvents
Picture3.Picture = Clipboard.GetData(vbCFBitmap)
Set Picture3.Picture = Picture3.Image '此时才真正显示Picture
'SavePicture Picture3.Image, "c:\kkkw.bmp"
End Sub
Private Sub Command2_Click()
Printer.PaintPicture Picture3.Picture, 0, 0, Picture3.Width, Picture3.Height
Printer.EndDoc
End Sub
有空你搜索下CBM666的代码,绝对能给你很大收获
vb.net 截屏 ,获取活动窗口

目的: 将屏幕按照指定坐标和大小进行截取成图,在picture1显示
问题: 大小是相同了,为什么截取的坐标不对,只是屏幕上的左上
相信大家都用过QQ截图功能。不过很多人并没有真正掌握好它的用法。将QQ截图与其它截屏和制图软件配合使用,会有意想不到的效果。
获取颜色的RGB值
我们在编辑图片或网页的时候,经常需要获取某种颜色的“RGB值”,所以很多人都安装了第三方的颜色吸取工具。其时用QQ截图键即可获取屏幕上任意颜色的RGB值。
当按下“Ctrl+Shift+A”弹出“截图”提示框时,提示框中的“当前像素RGB”即为当前鼠标屏幕位置的颜色RGB值,将鼠标移动到你想查看的屏幕颜色上即可获得相应的RGB值(如图1)。
图1精确截取图片大小
有时我们对要使用的截图尺寸有严格要求,比如论坛签名或QQ头像等。用QQ截图键可以按尺寸精确截取,一步到位无需再进行后期裁剪了。
按下QQ截图键,按住鼠标不放选取截取范围时,在鼠标上方会有一个信息框显示当前范围的详细信息,其中“矩形大小”就是以像素来表示的图片的尺寸大小,括号内的数字分别表示的是长和高(如图2)。松开鼠标调整截图框时,对照“矩形大小”就可以按需要的尺寸来精确截图范围,然后用鼠标点住截图框将截图框拖到要截取的图片上,双击即可获得所需尺寸的图片了。
图2图片拼贴好帮手
大部分的截图软件一次只能截取一张图片,当要截取多张图片并进行拼贴组合时,就需要一张一张截取全部保存后再进行拼贴操作,非常麻烦。
我们知道用QQ截图键截取的图片可以在任一个可以粘贴图片的程序中使用,这样只需用截图软件进行一次截图操作,剩下的图片用QQ截图键来截取,然后依次粘贴到截图软件的窗口中即可快速进行拼贴操作了,是不是很方便啊。
小提示:QQ截图键无需打开聊天窗口即可使用,截取的图片在任一可粘贴图片的程序窗口中如画图、Word等,使用“粘贴”命令即可使用
VB怎么做个截图工具
1. 启动新 VisualBasic 常用 Exe 项目。 默认情况下创建 Form 1。
2. 在 项目 菜单上, 选择将一个新模块添加到现有项目 添加模块 。
3. 向窗体, 名称之一添加两 图片框 Pic_Edit (目标), 和其他名称 Pic_Dest (目标)。
4. 将是 Pic_Edit Picture 属性设置为要从中选择区域位图
5. 将是 Pic_Dest AutoRedraw 属性设置为 True
6. 以下代码添加到 Module 1:Public Const INVERSE = 6
Public Const DOT = 2
Public Const SOLID = 0
Public OrigX As Long
Public OrigY As Long
Public DestX As Long
Public DestY As Long
Public Sub Draw_Selection_Rectangle()
' Set drawing mode to INVERSE since this routine also used to erase
' the selection rectangle by simply drawing over the currently
' displayed rectangle
With Editor.Pic_Edit
.DrawMode = INVERSE
.DrawStyle = DOT
Editor.Pic_Edit.Line (OrigX, OrigY)-(DestX, DestY), , B
.DrawStyle = SOLID
End With
End Sub
Public Sub Copy_Rectangle()
With Editor.Pic_Dest
.Cls
.Visible = True
.Height = DestY - OrigY
.Width = DestX - OrigX
.PaintPicture Editor.Pic_Edit, 0, 0, (DestX - OrigX), _
(DestY - OrigY), OrigX, OrigY, (DestX - OrigX), _
(DestY - OrigY), vbSrcCopy
End With
' Make sure the clipboard is clear, then copy the image:
Clipboard.Clear
Clipboard.SetData Editor.Pic_Dest.Image
End Sub
7. 以下代码添加到 Form 1:Private Sub Pic_Edit_MouseDown(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then Pic_Edit.Refresh
Pic_Dest.Visible = False
OrigX = X
OrigY = Y
DestX = OrigX
DestY = OrigY
Call Module1.Draw_Selection_Rectangle
End Sub
Private Sub Pic_Edit_MouseMove(Button As Integer, Shift As Integer, X As Single, Y As Single)
If Button = 1 Then
DestX = X
DestY = Y
Pic_Edit.Refresh
Call Module1.Draw_Selection_Rectangle
End If
End Sub
Private Sub Pic_Edit_MouseUp(Button As Integer, Shift As Integer, X As Single, Y As Single)
' Check to see if mouse moved or goes the "wrong" way:
If DestX = OrigX Or DestY = OrigY Then
Pic_Edit.Refresh
Exit Sub
End If
If Button = 1 Then Call Copy_Rectangle
End Sub
8. 启动应用程序并选择用鼠标与位图的区域。 当您松开鼠标按钮, Pic_Dest 出现 备注 所选区域: 如果备份 MS 画图、 MSWord 或任何其他应用程序可能需要粘贴位图, 打开您就可以粘贴到该应用程序图像的选定部分。 也可以通过剪贴板查看程序查看剪贴板的内容。
