Hello,
Do you mean that you want the capture to continue, but the preview pause?
If yes, there's no direct function to do it, but you might be able do it indirectly.
If not, please explain what you want to do exactly.
Also tell me whether you have a LEADTOOLS imaging toolkit or not.
Thanks,

this is not exactly what i want...
i just want to freeze the preview of the capture control (like a pause button on a VCR)... giving then the chance to the user to eventually take a stll image

Chris,
I'm still not certain about one point.
In your first message you wrote "freeze the preview while capturing".
By "capturing", do you mean video is being recorded to a file (such as AVI), or do you simply mean video is being displayed (previewed)?
This makes a lot of difference, because working with a capturing control is different from working with a previewing control.
Thanks,

Hello,
This means you are NOT recording to disk, is this right?

Hello,
To Freeze the preview please do the following:
- Add LtmmCapture control on your form (visible = True).
- Add PictureBox control on your form (visible = False).
- Add a button and use the following code:
+---------------------+
Private Sub Command1_Click()
If Capture1.VideoDevices.Selection = 0 Then
Capture1.StartCapture ltmmCapture_Mode.ltmmCapture_Mode_Still
Picture1.Picture = Capture1.GetStillPicture(500)
Picture1.Visible = True
Capture1.Visible = False
Picture1.Move _
Capture1.Left + Capture1.Width / 2 - Capture1.VideoWidth * Screen.TwipsPerPixelX / 2, _
Capture1.Top + Capture1.Height / 2 - Capture1.VideoHeight * Screen.TwipsPerPixelY / 2, _
Capture1.VideoWidth * Screen.TwipsPerPixelX, _
Capture1.VideoHeight * Screen.TwipsPerPixelY
Capture1.StopCapture
Capture1.VideoDevices.Selection = -1
Else
Picture1.BorderStyle = vbBSNone
Capture1.BorderStyle = ltmmNone
Capture1.BackColor = Me.BackColor
Capture1.VideoDevices.Selection = 0
Capture1.Preview = True
Capture1.VideoWindowSizeMode = ltmmNormal
Capture1.Visible = True
Picture1.Visible = False
End If
End Sub
+---------------------+
Please let me know if this helps.
