    Hi srbbd!


    You can take and save a picture of your form like this:

    Code:
    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)


    Private Const KEYEVENTF_KEYUP = &H2


    Private Function SaveFormPic() As Picture
       Dim pic As StdPicture
       Set pic = Clipboard.GetData(vbCFBitmap)
       keybdevent vbKeyMenu, 0, 0, 0
       keybd
    event vbKeySnapshot, 0, 0, 0
       DoEvents
       keybdevent vbKeySnapshot, 0, KEYEVENTFKEYUP, 0
       keybdevent vbKeyMenu, 0, KEYEVENTFKEYUP, 0
       DoEvents
       Set SaveFormPic = Clipboard.GetData(vbCFBitmap)
       Clipboard.SetData pic, vbCFBitmap
    End Function


    Private Sub Command1_Click()
       SavePicture Clipboard.GetData(vbCFBitmap), "C:\MyPic.jpg" 'picture location
    End Sub



    The example requires one command button. It will take a picture of your form and save it into file "c:\mypic.jpg". You can change that.


    Good luck.

    I'm sorry it didn't work. But this one will:

    Code:
    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)


    Private Const KEYEVENTF_KEYUP = &H2


    Private Function SaveFormPic() As Picture
      Dim pic As StdPicture
      Set pic = Clipboard.GetData(vbCFBitmap)
      keybdevent vbKeyMenu, 0, 0, 0
      keybd
    event vbKeySnapshot, 0, 0, 0
      DoEvents
      keybdevent vbKeySnapshot, 0, KEYEVENTFKEYUP, 0
      keybdevent vbKeyMenu, 0, KEYEVENTFKEYUP, 0
      DoEvents
      Set SaveFormPic = Clipboard.GetData(vbCFBitmap)
      Clipboard.SetData pic, vbCFBitmap
    End Function


    Private Sub Command1_Click()
      SavePicture SaveFormPic, "C:\MyPic.jpg" 'picture location
    End Sub



    Hope it works now...

    Thank you for this code, it works (nearly) great!


    There is a problem though that I experience. I wrote an application that surfs to an URL in the Webbrowser object (Internet Explorer object) and makes a screenshot every 3 seconds. In about 1 of 10 calls to the function SaveFormPic, the function doesn't copy the screen to the clipboard, but sends it to the printer. This results in displaying the Print window (Select Printer window) and thus the applications hangs. Also when the Silent property of the Webbrowser object is set to true, the problem remains.


    What can be the cause or the solution? Any help will be appreciated. Thank you!

    Hi jorrit77!

    I'm glad my code was helpful.

    Try clearing the clipboard each time the picture is taken and saved. That should fix the problem.

    The first example clears the Clipboard after the picture has been saved and the second one clears it before the picture has been taken or saved.

    Code:
    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)

    Private Const KEYEVENTF_KEYUP = &H2

    Private Function SaveFormPic() As Picture
     Dim pic As StdPicture
     Set pic = Clipboard.GetData(vbCFBitmap)
     keybd_event vbKeyMenu, 0, 0, 0
     keybd_event vbKeySnapshot, 0, 0, 0
     DoEvents
     keybd_event vbKeySnapshot, 0, KEYEVENTF_KEYUP, 0
     keybd_event vbKeyMenu, 0, KEYEVENTF_KEYUP, 0
     DoEvents
     Set SaveFormPic = Clipboard.GetData(vbCFBitmap)
     Clipboard.SetData pic, vbCFBitmap
    End Function

    Private Sub Command1_Click()
     SavePicture SaveFormPic, "C:\MyPic.jpg" 'picture location
     Clipboard.Clear
    End Sub


    ...or like this:

    Code:
    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)

    Private Const KEYEVENTF_KEYUP = &H2

    Private Function SaveFormPic() As Picture
     Clipboard.Clear
     Dim pic As StdPicture
     Set pic = Clipboard.GetData(vbCFBitmap)
     keybd_event vbKeyMenu, 0, 0, 0
     keybd_event vbKeySnapshot, 0, 0, 0
     DoEvents
     keybd_event vbKeySnapshot, 0, KEYEVENTF_KEYUP, 0
     keybd_event vbKeyMenu, 0, KEYEVENTF_KEYUP, 0
     DoEvents
     Set SaveFormPic = Clipboard.GetData(vbCFBitmap)
     Clipboard.SetData pic, vbCFBitmap
    End Function

    Private Sub Command1_Click()
     SavePicture SaveFormPic, "C:\MyPic.jpg" 'picture location
    End Sub


    One of these two samples should work.


    If the problem persists please let me know so I can fix it.
