TopazBasicNETDemo OVERVIEW

The Topaz SigPlus VB.NET demo demonstrates the basic functionality of SigPlus in the VB.NET environment. It provides the means to:
Sign using a Topaz tablet
Clear the signature
Save a Topaz SIG file
Load a Topaz SIG file
Save an image file of the current signature (JPG, TIF, BMP, WMF, and EMF)
Encrypt and Compress a signature, then pass the signature (as a long ASCII string) to another SigPlus object on a different form for re-display

HOW TO USE THE DEMO
SIGNING FORM
Run either the VB.NET project, or the EXE file generated, located in the TopazBasicNETDemo\bin directory. On the first form, you will a SigPlus object and 6 buttons near the bottom:

SIGN: Turns tablet on, ready for signing
CLEAR: Clears current signature from SigPlus object
SAVE SIG FILE: Saves the current signature as a SIG file on your machine
LOAD SIG FILE: Loads a previously saved SIG file back into SigPlus
SAVE IMAGE: Saves an image file (BMP, JPG, TIF, WMF, EMF) of the current signature
CLOSE: Ends the demo

The button and corresponding settings on the far right on this form are as follows:
PASS SIGNATURE TO NEXT FORM: This option encrypts and compresses the signature, then passes the signature (as a long ASCII string) to a global string variable. On the next form, a new Sigplus object is instantiated, and set up with the same encryption data, and encryption and compression modes as the original SigPlus object, so the signature may be re-displayed. (This ASCII string may be stored and later returned for real-life applications).
The user may indicate the compression and encryption modes of choice via the radio buttons (Mode1 or Mode2 for eac...for details on SigPlus encryption and compression, see the SigPlus.doc file located in your WIN\SigPlus\Docs directory after installation of SigPlus), and also decide on the encryption data string to encrypt the signature with, using the provided Text box. Once the button is pressed, the user is moved to the next form, and the now-encrypted and compressed signature is assigned to a global string variable.

DISPLAY FORM:
This form is activated when the user has clicked on PASS SIGNATURE TO NEXT FORM button from the previous form. This form contains a SigPlus object and two buttons:

LOAD SIGNATURE: This button will set up the SigPlus object on this form to successfully accept the signature from the previous form. It first passes the encryption string from the first form to the new SigPlus object. Next, the encryption mode and compression mode of this SigPlus object are set properly, according to the settings chosen on the previous form. SigPlus is now ready to accept the signature...as long as the encryption and compression modes match the previous settings, and the encryption data is the same, the signature will be returned. This demo is set up to be sure these values are retained properly. In a real application, if these values are different, the signature will NOT be returned. Once pressed, then, the signature will be redisplayed

GO BACK: Returns user to previous form
