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

'模块中

hDCtmp = GetDC(0)

BitBlt Picture1.hdc, 0, 0, picWidth, picHeight, hDCtmp, x, y, vbSrcCopy

ReleaseDC 0, hDCtmp

End Sub

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。
