網上下的VB.NET截屏程序,試過好用,哪位大俠給詳細解釋一下!另外,怎么把截圖加載到Picturebox里?

VB.NT用的是觸發(fā)事件,一按就會觸發(fā),要不你加個timer控件,延遲一秒

標題的問題:你先把圖片保存,再加載

c#如何實現(xiàn)類似qq一樣的截圖功能?

按快捷鍵后,先把整個屏幕截下來,然后顯示在form1上,form1是一個沒有邊框的窗體,之后最大化顯示form1,開始鼠標拖坐標,截取坐標內的圖片,保存,

vb模擬QQ 截圖

下面的代碼是我很欣賞的編程牛人CBM666的,你看下就應該能明白意思了,需要的haunted自己修改一下,我運行過了可以運行成功,不會截到其它窗體只是打印當前窗體

友情提示:你點下打印鍵的時候沒有提示會直接打印出窗口內容來,沒有確定取消的按鈕的,當初我在公司試的時候隨便貼了個很爛的圖就給打出來了,還被人笑了。。。

'添加 Picture1 Picture2 各別放一張圖片 窗體也可加圖片, 只是測試用罷了.

,Text1 隨便打一些內容,(只是測試用)

'再隨便加一個Picture3 用來保存圖片

'Command1 抓圖存圖 Command2 打印

'本代碼是將窗體內所有的控件與窗體一起保存到Picture3再打印出來.

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 '整個Screen

Const theForm = 1 '當前活動界面

Private Sub Form_Load()

Command1.Caption = "抓取窗體"

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 '此時才真正顯示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的代碼,絕對能給你很大收獲

vb.net 截屏 ,獲取活動窗口

'模塊中

hDCtmp = GetDC(0)

目的: 將屏幕按照指定坐標和大小進行截取成圖,在picture1顯示

問題: 大小是相同了,為什么截取的坐標不對,只是屏幕上的左上

相信大家都用過QQ截圖功能。不過很多人并沒有真正掌握好它的用法。將QQ截圖與其它截屏和制圖軟件配合使用,會有意想不到的效果。

獲取顏色的RGB值

我們在編輯圖片或網頁的時候,經常需要獲取某種顏色的“RGB值”,所以很多人都安裝了第三方的顏色吸取工具。其時用QQ截圖鍵即可獲取屏幕上任意顏色的RGB值。

當按下“Ctrl+Shift+A”彈出“截圖”提示框時,提示框中的“當前像素RGB”即為當前鼠標屏幕位置的顏色RGB值,將鼠標移動到你想查看的屏幕顏色上即可獲得相應的RGB值(如圖1)。

圖1精確截取圖片大小

有時我們對要使用的截圖尺寸有嚴格要求,比如論壇簽名或QQ頭像等。用QQ截圖鍵可以按尺寸精確截取,一步到位無需再進行后期裁剪了。

按下QQ截圖鍵,按住鼠標不放選取截取范圍時,在鼠標上方會有一個信息框顯示當前范圍的詳細信息,其中“矩形大小”就是以像素來表示的圖片的尺寸大小,括號內的數(shù)字分別表示的是長和高(如圖2)。松開鼠標調整截圖框時,對照“矩形大小”就可以按需要的尺寸來精確截圖范圍,然后用鼠標點住截圖框將截圖框拖到要截取的圖片上,雙擊即可獲得所需尺寸的圖片了。

圖2圖片拼貼好幫手

大部分的截圖軟件一次只能截取一張圖片,當要截取多張圖片并進行拼貼組合時,就需要一張一張截取全部保存后再進行拼貼操作,非常麻煩。

我們知道用QQ截圖鍵截取的圖片可以在任一個可以粘貼圖片的程序中使用,這樣只需用截圖軟件進行一次截圖操作,剩下的圖片用QQ截圖鍵來截取,然后依次粘貼到截圖軟件的窗口中即可快速進行拼貼操作了,是不是很方便啊。

小提示:QQ截圖鍵無需打開聊天窗口即可使用,截取的圖片在任一可粘貼圖片的程序窗口中如畫圖、Word等,使用“粘貼”命令即可使用

VB怎么做個截圖工具

1. 啟動新 VisualBasic 常用 Exe 項目。 默認情況下創(chuàng)建 Form 1。

2. 在 項目 菜單上, 選擇將一個新模塊添加到現(xiàn)有項目 添加模塊 。

3. 向窗體, 名稱之一添加兩 圖片框 Pic_Edit (目標), 和其他名稱 Pic_Dest (目標)。

4. 將是 Pic_Edit Picture 屬性設置為要從中選擇區(qū)域位圖

5. 將是 Pic_Dest AutoRedraw 屬性設置為 True

6. 以下代碼添加到 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. 以下代碼添加到 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. 啟動應用程序并選擇用鼠標與位圖的區(qū)域。 當您松開鼠標按鈕, Pic_Dest 出現(xiàn) 備注 所選區(qū)域: 如果備份 MS 畫圖、 MSWord 或任何其他應用程序可能需要粘貼位圖, 打開您就可以粘貼到該應用程序圖像的選定部分。 也可以通過剪貼板查看程序查看剪貼板的內容。
