After a long time of analyzing your code, and trying to understand it one thing still stands in my path, and that is the AxGrFingerXLib referenced file.

Look at this:

Notice I cannot initialize the reader because I don't have the same referenced library.

Please help me.

OK!

I've figured out how to create an interop assembly, and embed the activeX controls in the program.

HOWEVER, when I try to initialize the ActiveX library using this line:

GrFingerX.Initialize() I get an error with an invalid ActiveX State Exception.

Any help please??

UPDATE:

Ok I found the cause, but i am completely lost as to why it's doing this nonsense.

Here is my FULL code:

Imports GrFingerXLib

Public Class Form1
Dim err, temp As Integer
Public WithEvents _GrFingerX As New AxGrFingerXLib.AxGrFingerXCtrl

Private Sub MainForm_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim err, temp As Integer
err = _GrFingerX.Initialize()
If err < 0 Then
MessageBox.Show("Initialization Failed", "Error", MessageBoxButtons.OK)
Else
temp = _GrFingerX.CapInitialize()
End If
End Sub

Private Sub FormClose(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
_GrFingerX.Finalize()
_GrFingerX.CapFinalize()
End Sub

Private Sub AxGrFingerXCtrl1_SensorPlug(ByVal sender As Object, ByVal e As AxGrFingerXLib._IGrFingerXCtrlEvents_SensorPlugEvent) Handles AxGrFingerXCtrl1.SensorPlug
AxGrFingerXCtrl1.CapStartCapture(e.idSensor)
End Sub
End Class

On the line above that is bolded, when I set a breaker on it and run the program, I use the step through to trace line by line. When I get to the _GrFingerX.Initialize(), it gives me the error I posted before this UPDATE. But when I trace the program, and place my cursor over the _GrFingerX in the bolded line above and view the properties, then trace through, it doesn't give me an error, HOW IS THAT POSSIBLE?????

Here is the error:

Nevermind, I figured it all out. I just made another class similar to your Util class, and it works!

Ill keep you guys posted on my updates. i know I'm going to need more help.

Thanks for this great user-friendly SDK, and your samples!

By the way, how do I get rid of the splash screen that starts up with the program? Do I need to buy it?

Dear Simjay,

The splash screen is only on Trial version. The registered version does not have it.

Best Regards,
