Question:

[WP8] Access Violation Error - SendEmail - Windows Phone Runtime Component

Jun 13 '14 at 11:42

First of all, warm greetings to all the members of this forum. I have just registered and this is my first post here. :)

Getting back to the business..

I am evaluating the Chilkat Windows Phone Runtime Component (http://www.chilkatsoft.com/winPhone.asp) for its IMAP and POP support for Windows Phone 8 XAML/C# app. But, am facing issues while trying to send an email through SMTP server using this Component on WP8. I have already searched through this forum, but did not find a discussion on the issue I am facing, hence this question.

Following is the code snippet that I have in OnNavigatedTo() of MainPage.xaml.cs in WP8 App:

        // Initialize mail manager..
        Chilkat.MailMan mailMan = new MailMan();
        mailMan.UnlockComponent("30-day trial");
        mailMan.SmtpHost = "smtp.xyz.com";
        mailMan.SmtpPassword = "decoderPassword";
        mailMan.SmtpUsername = "decoder@xyz.com";
        mailMan.SmtpPort = 587;

        mailMan.OpenSmtpConnection();

        // Form an email to send..
        Email mail = new Email();
        mail.FromAddress = "decoder@xyz.com";
        mail.From = "decoder@xyz.com";
        mail.FromName = "Decoder";
        mail.AddTo("Decoder-Gmail", "decoder@gmail.com");
        mail.Subject = "Test Mail";
        mail.Body = " This is a test mail.";

        if(!mailMan.IsUnlocked())
        {
            MessageBox.Show("MailMan not unlocked: " + mailMan.LastErrorText);
            return;
        }
        if (mailMan.IsSmtpConnected)
        {
            // Send email..
            bool bSendResult = mailMan.SendEmail(mail);
            if (bSendResult == true)
                MessageBox.Show("Mail sent successfully.");
            else
                MessageBox.Show("Mail send failed: " + mailMan.LastErrorText);
        }
        else
        {
            MessageBox.Show("Failed to connect to SMTP server: " + mailMan.LastErrorText);
        }

When mailMan.SendEmail(mail) is executed, it triggers an Access Violation Exception.

Exception Details:

System.AccessViolationException was unhandled HResult=-2147467261 Message=Attempted to read or write protected memory. This is often an indication that other memory is corrupt. InnerException: null

Note: I am using the 30 day-evaluation and have set the Unlock Component to "30-day Trial" in mailMan.

Can you please help me resolve this issue? Has anyone encountered this issue or been able to successfully use this component for WP8?
