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

VB截取程序截图

这是截屏代码,程序运行后3秒截屏,并在vb上显示且保存图片在d:\zt文件夹里。对于GetDC(GetActiveWindow), 0, 0, vbSrcCopy '抓屏中的0,0是截取的坐标,你可以调整坐标来控制截取的区域,0,0为全屏

Private Declare Function GetDC Lib "user32" (ByVal hwnd As Long) As Long

Private Declare Function BitBlt Lib "gdi32" (ByVal hDestDC As Long, ByVal X As Long, ByVal Y As Long, ByVal nWidth As Long, ByVal nHeight As Long, ByVal hSrcDC As Long, ByVal xSrc As Long, ByVal ySrc As Long, ByVal dwRop As Long) As Long

Private Declare Function GetActiveWindow Lib "user32" () As Long

Dim a

Private Sub Command1_Click()

Timer1.Enabled = True

End Sub

Private Sub Form_Load()

On Error Resume Next

MkDir "d:\zt" '建文件夹

Me.AutoRedraw = True

End Sub

Private Sub Timer1_Timer()

a = a + 1

If a = 3 Then '三秒后开始抓屏

Me.Hide

BitBlt Me.hDC, 0, 0, Screen.Width, Screen.Height, _

GetDC(GetActiveWindow), 0, 0, vbSrcCopy '抓屏

Me.Show

Dim sFile As String

sFile = "d:\zt\" Format(Now, "yyyymmddhhmmss") ".BMP"

SavePicture Me.Image, sFile '保存Me.hDC

Timer1.Enabled = False

End If

End Sub

VB截取屏幕

[DllImport("user32.dll", EntryPoint = "GetDC")]

public static extern IntPtr GetDC(IntPtr hWnd);

[DllImport("user32.dll", EntryPoint = "ReleaseDC")]

public static extern IntPtr ReleaseDC(IntPtr hWnd, IntPtr hDC);

[DllImport("user32.dll", SetLastError = true)]

static extern IntPtr FindWindowEx(IntPtr hwndParent, IntPtr hwndChildAfter, string lpszClass, string lpszWindow);

[DllImport("user32.dll", SetLastError = true)]

static extern IntPtr FindWindow(string lpClassName, string lpWindowName);

先找到你要截图的那个窗体的 句柄 然后根据这个句柄得到改窗体的DC 创建一个bitmap 然后填充 得到的bitmap后 显示到picturebox里面
