VB

err = m_SecuBSP.Capture(FIRPurpose.VERIFY)
       If (err = BSPError.ERROR_NONE) Then
           m_CaptureFIRText = m_SecuBSP.FIRTextData
       End If

       DisplaySecuBSPErrMsg("Capture", err)


       Dim MyHandle As IntPtr = fpWindow.Handle

       'Or to get the image from the PictureBox

       Dim MyImage As Image = fpWindow.Image
       PictureBox1.Image = MyImage

What I have tried:

VB

err = m_SecuBSP.Capture(FIRPurpose.VERIFY)
      If (err = BSPError.ERROR_NONE) Then
          m_CaptureFIRText = m_SecuBSP.FIRTextData
      End If

      DisplaySecuBSPErrMsg("Capture", err)


      Dim MyHandle As IntPtr = fpWindow.Handle

      'Or to get the image from the PictureBox

      Dim MyImage As Image = fpWindow.Image
      PictureBox1.Image = MyImage

As far as I know, you can't.

The string is a summary of the identifiable parts of the print, essentially, it's a hash of the feature data. It can't be used to rebuild an image of the fingerprint.

For further information on the SDK, you're going to have to ask SecuGen support.

Again, AS FAR AS I KNOW, what you're dealing with is a LOSSY HASH of the data. A hash is a summary of the data that loses the original data and cannot be used to get the original data back.

There is no way to create an image from that hash.

Again, AS FAR AS I KNOW. I know nothing about the library you're using, so your BEST SOURCE of information is going to be the manufacturer of the library and its documentation.

i m used secuBSPMx.net

---- my code is below ---------

Dim err As BSPError
m_SecuBSP.CaptureWindowOption.WindowStyle = WindowStyle.INVISIBLE
m_SecuBSP.CaptureWindowOption.ShowFPImage = True
m_SecuBSP.CaptureWindowOption.ShowFPImage = True
m_SecuBSP.CaptureWindowOption.FingerWindow = pbThumb.Handle

err = m_SecuBSP.Capture(FIRPurpose.VERIFY)
If (err = BSPError.ERROR_NONE) Then
m_CaptureFIRText = m_SecuBSP.FIRTextData
End If
DisplaySecuBSPErrMsg("Capture", err)

------------------------------------------
i got string data of fingure print
now what is the process to obtain image of thumb ?
