Does anyone have experience with the Griaule SDK and fingerprint readers? Do anyone have any documentation that explains the various ActiveX controls and invoke nodes? The manufacturer is not being very helpful and, without any guidance on for the ActiveX controls, I am having a hard time figuring this out.
At this point, I just want to communicate with a Futronic FS80 print scanner and show an image on the screen (no identification needed).
Thanks for your time and I appreciate any advice you may have.

Displaying the image is actually the toughest part to do in LabVIEW. You'll have to use a Microsoft Forms control or purchase George Zou's Image Toolbox (not available for LV 2010). In his toolbox, there is a "Bitmap handle to Image Cluster" function that converts hbitmap to an image data cluster. From there, you can use the standard "Draw Flattened Pixmap" VI to convert the image data cluster to a LabVIEW picture control data type. Unfortunately, George's Image Toolbox does not have diagrams, so it does not compile forward or backward to other versions of LabVIEW.
I did not have much success with the Microsoft Forms control since I'm a G programmer (not VB or .NET).

If you just want to see that your fingerprint reader is working, you can evaluate Blue Ridge Test's Biometric Login Toolkit for free after downloading and installing it from the LabVIEW Tools Network. If you're not doing Login, then you can technically skip the SQL Server portions of the install. Then, from the included Example Biometric Login Application EXE, run diagnostics. Your Futronic FS80 is a supported reader.
