i use a cam , with lan port and internal web server. the cam takes picture automatically because has motion detection. these image are already forwarded to my mail everyday. so we (you 
) should think HS to receive these mails from the cam (they come from a specific account , so ONLY mails from the cam and they have pictures as JPEG attachment).

hey, be patient with me 
I will create the script which checks the file on a file location. Downloading an attachment is another way of saving the file to a location. (next step?)
Is the image you have used to test a picture of your environment, because when i use this one (http://www.abmulderbv.nl/dynimg/1970/14 ... nteken.jpg) i will get "null" back and if using this one (http://www.seat-club.nl/stickerzone/ind ... eken2k.jpg) i get Z3NKFS. Did you tweaked the config.xml ?

i'm playing with plates images. if we use the archive of the sw it works very well.
i used an image of italian plate, but i can not be recognized, so i did a trick : copy and paste that plate with "paint" in one of the car in the archive and it works 80%. must work on config.xml ? where ? dimensions ? what else?

i think it has something to do with the image specs. (dimension, colordepth)big difference?
First step!
1. Save this code to a script (getlicenseplate.vb as an example)
2. change the values of the 3 variables (strDevice, strPathJavaANPR and strInputImage) to the correct value
3. create an event that has a script action to this script.
4. create two additional events called Legal license plate detected and Illegal license plate detected. The first event will be triggered if the license plate is on the list (see next bullet). Obvious, the second event, if it isn't on the list. (example would be to send you an email with the image as attachment)
5. in your HS config directory create a file called LPR.ini. The first line has to be something, i'd written allowed license plates. The additional lines you put in the license plates which are allowed.
Hit it and give feedback. The one thing that has to be arranged is to export the attachment from the mail.
First step!
1. Save this code to a script (getlicenseplate.vb as an example)
Code: Select all
Sub Main(parm as object)
Dim strFileContentConfig, strFileContentLPR,strDevice, strPathJavaANPR, strInputImage As String
strDevice = "V11" ' which device has to get the license plate number as value
strPathJavaANPR = "C:\temp\javaanpr\javaanpr\dist" ' location of the javaanpr.jar
strInputImage = "C:\temp\test_005.jpg" ' complete path to the image to be OCRd
Shell("cmd /c cd " & strPathJavaANPR & " && java -jar javaanpr.jar -recognize -i " & strInputImage & " >" & Environ("windir") & "\ocrLPR.txt", , True)
strFileContentConfig = My.Computer.FileSystem.ReadAllText(hs.GetAppPath & "\config\LPR.ini")
strFileContentLPR = My.Computer.FileSystem.ReadAllText(Environ("windir") & "\ocrLPR.txt")
hs.SetDeviceString(strDevice, strFileContentLPR.Trim, True)
If instr(uCase(strFileContentConfig), uCase(strFileContentLPR.Trim)) > 0 Then
hs.TriggerEvent("Legal license plate detected")
Else
hs.TriggerEvent("Illegal license plate detected")
End If
End Sub

Alexander i did it. it works and email arrives, but if you launch it 2-3 times , then you have " running event in bckg" and email does not exit.

Can you clarify "then you have " running event in bckg" and email does not exit.", because i don't understand this part of your post.

Not even after a few seconds? Because i can't understand why it won't run a second time. It's like it cant run because the command prompt is stull running from the previous run. That is something i would think of having problem with. Please check if java.exe and/or cmd.exe aren't running anymore on the HS server when you try again.

None of java or cmd are running on server. it seems to wait for something, but HS doesn't crash and all other functions are working.

i launched the script with Task manager open , i see cmd.exe and java.exe starting and closing after 2sec.

so thats okay. If i run it two times, i do get this:
Can you put this code between most of the lines of code and change "1" to different one, so that you know which one you would expect to log after the last one has logged itself? Maybe than we can find the line of code that gives a problem (if so)
