View 5 RepliesSerialization - Deserialize Digital Persona Template?
Oct 19, 2010Reading binary data out of the database, and I need to convert it back into a Digital Persona fingerprint template. I'm not familiar with serialization and deserialization, Here's what I tried:
Dim rsBioData As SqlDataReader = SQL.ExecuteReader
Dim byteTemplate As Byte
Dim memStreamTemplate As MemoryStream
If rsBioData.HasRows Then
While rsBioData.Read
[Code] .....
I receive an error that template.DeSerialize(memStreamTemplate) does not create a value.
Here's how I serialized the object to place it into the database. I assume this part is working, since the binary data shows up in SQL server--just can't read it back out to see.
Dim str As New MemoryStream
Enroller.Template.Serialize(str)
Dim serializedTemplate As Byte() = str.ToArray()
SQL.Parameters.AddWithValue("biometricData", serializedTemplate)

VS 2008 - Read A 16bit Binary File (tif Image) And Pixel Values Of The Image Ranges From 1200 To 4500 - EndOfStreamException Unhandled Error
Mar 18, 2012I am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

View 1 Replies2010 FingerPrint Application
Jun 5, 2011I am clueless on the whole thing and been reading a lot about it. So far, I saw some samples which are poorly documented and oritend to vb.net 2005. Is there any SDK oriented to vb.net 2010 and well-documented? After converting 2005->2010, it gives me errors and so I can't see the samples. Gruile SDK seems to work fine but it is very badly documented. I donno how it is initialized and interacted with at all as their API reference is poorly written.

View 1 RepliesSerial Port Programing For Digital I/O?
Aug 27, 2009Im an electrical engineering student, and I am trying to utilize the serial port to give me high and low digital states. What i want to do is simply turn on an LED or turn it off. the basic gist of what I have been trying currently is that on a button click, serialPort1.DTREnable = enabled or disabled, indefinitely until the next button click.
So far, I have only been able to get the LED to momentarily flash... It seems to begin in an active state flash off, then immediately, return to its active state. I am using Visual Studio 2008. Can I use DTREnable to generate on/off states by enabling or disabling the pin? Is there a tutorial somewhere for electrical engineering applications using visual studio 2008?
