'Gets the total number of frames in the .tiff file

'Adds number of frames to the combo box for displaying purposes.
Dim i As Integer
For i = 0 To totFrame - 1

cboFrameNo.Items.IndexOf(1)

'Sets the temporary folder to "C:\temp\"
Dim strPath As String
strPath = "c:\temp\"

'Saves every frame as a seperate file.
Dim z, curF As Integer
z = 0
curF = 0'curF是页码
For z = 0 To 1'(totFrame - 1)
objImage.SelectActiveFrame(objDimension, curF)
objImage.Save(strPath & curF & ".tif", Imaging.ImageFormat.Tiff)
curF = curF + 1
Next
