Use Digital Certificates In Program Application?
Jun 22, 2009Here is my issue/question. I am relatively new to VB.Net programming, and I have been assigned the task of creating an application that will go out to a Secure web site and download a file. My first issue is it best to do this using a Windows form, ASP.Net or what. My second and main question is how do I authenticated to the secure web site in .net code?
Upon connecting to the secure web site it asks me for a certificate, which at the moment I have to manually present, however we would like to automate this. Then after it authenticates I have to go a few more pages in before i get to the file that needs to be downloaded.Although this file changes daily it has the same key tag so I can hardcode that into the download application. I just need to figure out how to programically authenticate to the site with .Net

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?

View 1 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)
