PRINTSCREEN这个命令具体怎么用看下帮助

希望我的回答对你有所帮助

如有其他问题，可以继续追问，您的采纳是我前进的动力！

vb.net 如何保存当前页为图片

提供两个思路

用printscreen,将其保存到文件，再调用outlook发出去，但是您说的超出一屏，就麻烦了；

以下代码保存为文件，引用自MSDN，由于我的SD版本不支持我的outlook,所以暂时无法给发送邮件的例子，请参考吧！

system.Windows.Forms.SendKeys.Send("%{PRTSC}")

If Not System.Windows.Forms.Clipboard.GetDataObject() Is Nothing Then

Dim oDataObj As IDataObject = System.Windows.Forms.Clipboard.GetDataObject()

If oDataObj.GetDataPresent(System.Windows.Forms.DataFormats.Bitmap) Then

Dim oImgObj As System.Drawing.Image = oDataObj.GetData(DataFormats.Bitmap, True)

'To Save as Bitmap

oImgObj.Save("F:\Test.bmp", System.Drawing.Imaging.ImageFormat.Bmp)

'To Save as Jpeg

oImgObj.Save("D:\Test.jpeg", System.Drawing.Imaging.ImageFormat.Jpeg)

'To Save as Gif

oImgObj.Save("d:\Test.gif", System.Drawing.Imaging.ImageFormat.Gif)

End If

2.另外出出报表，再调用outlook发出去，只给出数据性报表，而不一定是窗体本身；

如何在VB中保存图片

VB6.0可使用SavePicture 语句来保存窗体或图像框中经修改的图片。

1）SavePicture 语句，从对象或控件（如果有一个与其相关）的 Picture 或 Image 属性中将图形保存到文件中。

说明：无论在设计时还是运行时图形从文件加载到对象的 Picture

属性，而且它是位图、图标、元文件或增强元文件，则图形将以原始文件同样的格式保存。如果它是 GIF 或 JPEG 文件，则将保存为位图文件。

2）AutoRedraw 属性，返回或设置从图形方法到持久图形的输出。

该属性为True，可使 Form 对象或 PictureBox

控件的自动重绘有效。图形和文本输出到屏幕，并存储在内存的图象中。该对象不接受绘制事件，必要时，用存储在内存中的图象进行重绘。

以下代码保存窗体装载并进行文字修饰的图片：

Option Explicit

Private Sub Command1_Click()

SavePicture Image, App.Path "\TEST" ' 将图片保存到文件。

End Sub

Private Sub Form_Click()

FontSize = 24

Print " 将图片保存到文件"

End Sub

Private Sub Form_Load()

Me.AutoRedraw = True

End Sub

3）若要保存为JPG图片需要采取使用API函数实现。参考以下步骤和代码：

a.在图片框加载需要添加文字水印的图片。

b.使用如下代码实现添加文字到图片框。

Private Sub CmdEdit_Click() '修改

Dim strTxt As String

strTxt = "风雨无阻拍摄"

Picture1.FontSize = 18

Picture1.CurrentY = Picture1.ScaleHeight - 30

Picture1.CurrentX = Picture1.ScaleWidth / 2 - Picture1.TextWidth(strTxt) / 2

Picture1.ForeColor = vbWhite

Picture1.FontItalic = True

Picture1.Print strTxt

End Sub

c.将以下API转换图片格式代码放置于标准模块，模块命名为saveApg。

Option Explicit

Public Type GUID

Data1 As Long

Data2 As Integer

Data3 As Integer

Data4(0 To 7) As Byte

End Type

Public Type GdiplusStartupInput

GdiplusVersion As Long

DebugEventCallback As Long

SuppressBackgroundThread As Long

SuppressExternalCodecs As Long

End Type

Public Type EncoderParameter

GUID As GUID

NumberOfValues As Long

type As Long

Value As Long

End Type

Public Type EncoderParameters

Count As Long

Parameter As EncoderParameter

End Type

Public Declare Function GdiplusStartup Lib "GDIPlus" (token As Long, inputbuf As GdiplusStartupInput, ByVal outputbuf As Long) As Long

Public Declare Function GdiplusShutdown Lib "GDIPlus" (ByVal token As Long) As Long

Public Declare Function GdipCreateBitmapFromHBITMAP Lib "GDIPlus" (ByVal hbm As Long, ByVal hpal As Long, Bitmap As Long) As Long

Public Declare Function GdipDisposeImage Lib "GDIPlus" (ByVal Image As Long) As Long

Public Declare Function GdipSaveImageToFile Lib "GDIPlus" (ByVal Image As Long, ByVal fileName As Long, clsidEncoder As GUID, encoderParams As Any) As Long

Public Declare Function CLSIDFromString Lib "ole32" (ByVal str As Long, id As GUID) As Long

Public Declare Function GdipCreateBitmapFromFile Lib "GDIPlus" (ByVal fileName As Long, Bitmap As Long) As Long

Public Function PictureBoxSaveJPG(ByVal pict As StdPicture, ByVal fileName As String, Optional ByVal quality As Byte = 80) As Boolean

Dim tSI As GdiplusStartupInput

Dim lRes As Long

Dim lGDIP As Long

Dim lBitmap As Long

'初始化 GDI+

tSI.GdiplusVersion = 1

lRes = GdiplusStartup(lGDIP, tSI, 0)

If lRes = 0 Then

'从句柄创建 GDI+ 图像

lRes = GdipCreateBitmapFromHBITMAP(pict.Handle, 0, lBitmap)

If lRes = 0 Then

Dim tJpgEncoder As GUID

Dim tParams As EncoderParameters

'初始化解码器的GUID标识

CLSIDFromString StrPtr("{557CF401-1A04-11D3-9A73-0000F81EF32E}"), tJpgEncoder

'设置解码器参数

tParams.Count = 1

With tParams.Parameter ' Quality

'得到Quality参数的GUID标识

CLSIDFromString StrPtr("{1D5BE4B5-FA4A-452D-9CDD-5DB35105E7EB}"), .GUID

.NumberOfValues = 1

.type = 4

.Value = VarPtr(quality)

End With

'保存图像

lRes = GdipSaveImageToFile(lBitmap, StrPtr(fileName), tJpgEncoder, tParams)

'销毁GDI+图像

GdipDisposeImage lBitmap

End If

'销毁 GDI+

GdiplusShutdown lGDIP

End If

If lRes Then

PictureBoxSaveJPG = False

Else

PictureBoxSaveJPG = True

End If

End Function

d.使用以下代码实现将加好文字水印图片保存为jpg格式图片。

Private Sub Command3_Click() '保存为.jpg图片

' 设置“CancelError”为 True

CommonDialog1.CancelError = True

On Error GoTo ErrHandler

' 设置标志

CommonDialog1.Flags = cdlOFNHideReadOnly

' 设置过滤器

CommonDialog1.Filter = "JPEG Files" "(*.jpg)|*.jpg"

' 指定缺省的过滤器

CommonDialog1.FilterIndex = 2

' 显示“打开”对话框

CommonDialog1.ShowSave

' 显示选定文件的名字

'MsgBox CommonDialog1.fileName

Set Picture2.Picture = Picture1.Image '转移Picture1所绘图为Picture2.Picture赋值

Dim ret As Boolean

ret = PictureBoxSaveJPG(Picture2, CommonDialog1.fileName) '保存压缩后的图片

If ret = False Then

MsgBox "保存失败"

End If

Exit Sub

ErrHandler:

' 用户按了“取消”按钮

Exit Sub

End Sub

VB2010或VB.NET 怎么能将自身窗体的所有内容保存为图片

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click

System.Windows.Forms.SendKeys.Send("%{PRTSC}")

Delay(0.1)

Dim bmp As Bitmap = CType(Clipboard.GetDataObject().GetData(DataFormats.Bitmap), Bitmap)

bmp.Save("c:\test1.jpg", System.Drawing.Imaging.ImageFormat.Jpeg)

End Sub

Private Sub Delay(ByVal tim As Single)

Dim t As Single = Microsoft.VisualBasic.Timer + tim

While t Microsoft.VisualBasic.Timer

My.Application.DoEvents()

End While

End Sub
