Alarm Program-Email Pictures not working in v1.1.15, were working in v526

General Troubleshooting and Support
1

I had the following program working in v526 in Raspbian Stretch Mono 5.4. It now refuses to send the pictures taken by my cameras. I got this program from the previous Homegenie Forum. It refuses to compile in v1.1.15 without errors.

// when the widget button is pressed, an e-mail is sent with pictures from cameras

// This app works for the following 2 FOSCAM IP cameras:
//   FI8910W: http://<cameraID>.myfoscam.org:<port>/snapshot.cgi?user=<username>&pwd=<password>
//   FI9821W: http://<cameraID>.myfoscam.org:<port>/cgi-bin/CGIProxy.fcgi?cmd=snapPicture2&usr=<username>&pwd=<password>&

// tried calling data from Generic IP Camera app - nothing happened (no error, nothing), although the URL
// worked fine in a browser:
//   byte[] img = Net.Webservice(http://<HG address>/api/Media.IpCamera/1/Camera.GetPicture).GetBytes();

// When I tried .WithCredentials, the e-mail was NOT sent - error message displayed.

var subject = Program.InputField("Email.Subject").Value;
var recipients = Program.InputField("Email.Recipients").Value;
var messageText = Program.InputField("Email.Message").Value;
var cameraOneImageURL = Program.InputField("IPCamera.ImageURLOne").Value;
//var cameraOneUsername = Program.InputField("IPCamera.UsernameOne").Value;
//var cameraOnePassword = Program.InputField("IPCamera.PasswordOne").Value;
var cameraTwoImageURL = Program.InputField("IPCamera.ImageURLTwo").Value;

if ((recipients != "") && (messageText != ""))
{
  Program.RunAsyncTask(() => {
    byte[] img;
    for (int x=0; x<3; x++) {
      if (cameraOneImageURL != "") {
    	img = Net.WebService(cameraOneImageURL)
//          .WithCredentials(cameraOneUsername, cameraOnePassword)
          .GetBytes();
		Net.AddAttachment( "first"+x+".jpg", img );
      }
      if (cameraTwoImageURL != "") {
	    img = Net.WebService(cameraTwoImageURL)
          .GetBytes();
		Net.AddAttachment( "second"+x+".jpg", img );
      }
   	  Pause(1);
    }
    
    if (Net.SendMessage(recipients, subject, messageText) == true)
      Program.Notify("E-Mail Pictures", "SUCCESS! Pictures sent.");
    else Program.Notify("E-Mail Pictures", "ERROR: Pictures **NOT** sent.");
  });
}
else
  Program.Notify("E-Mail Pictures", "ERROR: Missing input field(s) - recipients and/or message text.");

When I run the program the following is outputted

A mail is being sent with no attachments so the email sending is working fine.

Could someone running v1.1.15 try compiling this program and tell me what errors they observe

2

I should have mentioned that compiling this program in v1.1.15 throws up an error “Obsolete string” yet its compiles perfectly in v526.

I’m not a C# programmer but it looks like there’s something in this code that v1.1.15 does not like. The Newtonsoft JSON Serializer clearly doesn’t like something here.

3

Yes, the bug was related to Newtonsoft can’t serialize MemoryStream objects and those objects are used in mail attachments.

Try this HomeGenie.exe (298 KB), it should fix the errors with sending email messages.

PS. At the moment I wasn’t able to compile your automation program as my HG installation is in non-working state))

4

Thanks Bounz.

I’m using Raspbian so I’ll just drop that file into my HG folder and overwrite the one that’s currently there.

Any idea how this occurred between the two versions.

5

That sorted the problem. The program is actually working better now.

Thanks for the update

6

The problem has arisen because I added logging of outgoing messages (https://github.com/Bounz/HomeGenie-BE/blob/master/HomeGenie/Automation/Scripting/NetHelper.cs#L246) to troubleshoot email problems, but unfortunately, I haven’t tested it with an email with attachments…

7

Well it’s working fine with attachments now
