How can I take pictures using a digital camera based on a button click in WinForm application? I tried googling, and got WIA. Used WIA 2.0 and wiaut.dll, and it is working fine for webcams. But I am not able to automate the actions of my Sony W220 camera. I tried googling for WPD, but it appears to be active only in Windows 7 and Vista, and I am using XP Sp2

I'm looking for guidence on using digital certificates to manage website user authenication and access. i am using a website that has this and what happens is this... the company issued me a personal certificate, that i installed on my local machine. When i connect to the website it checks my local cert store for a cert issued by them and if none is found, no entry, if multiple are found, then a box displays to allow you to pick which one to use.
View 1 RepliesIm 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?
Here 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
I'm looking for a library compatible with microsoft.net framework that allows the creation and verification of XAdES signatures (XAdES, XAdES-C, XAdES-XL, etc...).It is important that the library enable the programmer to choose:
1.- Type of certificate to use in the signature process (PFX file, Windows centralized store, SmartCard)
2.- CRL to validate the certificate.
3.- Possibility to include Time stamping on the signature.
4.- Possibility to include OCSP response on the signature.
All I found are libraries in Java, but have not found any libraries in .NET.
I am trying to design a digital clock using the drawing tool. i have drawn all the segments using the drawpen function and i have also created a timer that will get the current system time. i want to link the current system to the digital display i have drawn, so that when the time is 1:02 for example only that will highlight on the digital display

View 3 RepliesHow do I get my form to display a simple digital counter? I have a "record" function on my program:
Private Sub Button13_Click_1(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click
mciSendString("open new Type waveaudio Alias recsound", "", 0, 0)
mciSendString("record recsound", "", 0, 0)
End Sub
I want to have a simple digital counter display while the program is recording. That way the user can know how long the audio is so far while recording. Then when the user is done recording, the timer will stop.
Reading 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)
