I try to move PocketSignature to Wince.NET4.2,
but when it calls
byte[] encryptData = Crypto.Encrypt(
Global.Settings.GetString(Passphrase),
_signature.SignatureBits);
It throw MissFunction Exception.
I find it goes wrong when invoke the WinApi
But It runs well on PocketPC Emulator.
Who can help me?!
Thanks forward!
 
I remember running into this a long while back - the issue was in the
Crypto class included in that MSDN Pocket Signature sample - it made
an assumption about the name of the Microsoft Cryptographic
provider DLL as named in the device registry and it was not the same
name for WinCE 4.2 devices.

If you could post the lines from the Crypto class that are in that sample,
I'll send you the correct name. Sorry I don't have this handy - I only
worked with that sample briefly to consider alternate approaches to
signature capture but have since moved to my own custom classes.

hi yy,
Can you please let me know which format do you use to save signature in
PPC? I'm now finding the way to save signature in JPEG format in PPC. I
have a sample to save it in BMP format. I think it will be possible if
I convert BMP image to JPG format but it might be long way.
