POST failured with big Content-Length - Integration with EWS Microsoft Exchange Server

I am try to teste integration with EWS WebServer (Use EWS to import an item by using the MIME stream) . In my test it works perfect up to 200k Content-Length.

Content greater than 200k I have problems. I try PostXml and SynchronousRequest But only small content works.

He does not even begin to negotiate NTLM.

Log Session:

Is there a super fast way to detect if a URL is no longer valid?

When fetching feeds (for instance) sometimes a particular feed will have been discontinued and the URL is no longer valid. When I hit one of these the delay is equal to the connect timeout setting (say 5 seconds).

Is there a super fast way to detect if a URL is no longer valid?

Thanks!

Few Questions on Zipping using Chilkat ActiveX in Delphi

Hi,

I am trying out your ActiveX Zip component in Delphi. These are a few issues that are unclear.

1) 'OnProgressInfo' event gives 'File not found' for all skipped files, even if it is skipped due to open or access denied.

2) How to save zip on abort?

3) How to show progress of each data file? 'OnPercentDone' event is there for entire zip and not for single data file.

4) How to use ChilkatZip1.HeartbeatMs property and AbortCheck event.

The return email address when using a Hotmail account

Ok, so I have this code:

//  Set the SMTP server.
mailman.put_SmtpHost("smtp.live.com");

//  Set the SMTP login/password (if required)
mailman.put_SmtpUsername("xxx");
mailman.put_SmtpPassword("yyy");

//  Connect to SMTP port 465 using TLS.
mailman.put_SmtpSsl(true);
mailman.put_SmtpPort(25);

But, my account uses email aliases. So, I do this:

//  Create a new email object
CkEmail email;

email.put_Subject("Monthly workbook data");
email.put_Body("Please find attached the latest monthly workbook data.");
email.put_From("Andrew Truckle <ccc>");
success = email.AddTo("PTS Support", "ddd");
//  To add more recipients, call AddTo, AddCC, or AddBcc once per recipient.

The email sends through OK. But when I hit reply, it is going to xxx. It has not honoured the alias ccc I had specified. Why is this?

Zipping attachments

At the moment I create a ZIP file myself using the Artpol Software library:

CZipArchive zipArchive;
zipArchive.Open(strBackupPath, CZipArchive::zipCreate);
zipArchive.SetGlobalComment(_T("Monthly Workbook Data"));
zipArchive.AddNewFile(strMWBFile, CZipCompressor::levelDefault, false);
zipArchive.Close();

//  Add some attachments.
//  The AddFileAttachment method returns the value of the content-type it chose for the attachment.
const wchar_t *contentType = email.addFileAttachment(strBackupPath);

It was bought to my attention that the CkEmailW object has a ZipAttachments method. I have some questions about it:

  1. Is it possible for us to support adding a global comment?
  2. Is it possible for us to support specifying the compression level?
  3. Does it matter what content the attachments are? Mine will be Unicode or UTF8 text files in up to 40 languages.

Thanks for the clarification. This is so I can decide if there will be an advantage to using ZipAttachments as opposed to my own methodology.

Thanks.

Is it possible to support some kind of progress monitoring when creating an email, attaching the file and then sending it and closing the connection?

OK, I have located this in the documentation for an eventProgressInfo. How do I go about using these call backs please? I am using the Unicode library with Visual C++ MFC Visual Studio 2017.

Using my own OAuth2 token with mailman?

July 19, 2017, 9:15 am

I have looked at the documentation about GMail and I quote:

GMail: If sending via smtp.gmail.com, then send with OAuth2 authentication if possible. Otherwise you will need to change your GMail account settings to allow for sending by less secure apps. See the links below.

I have reviewed the sample code that uses your HTTP library for the task in hand. However, I am already having to fund the Email library and at the moment it is beyond my circumstances to purchase an additional library.

Now, I have already written my own VB.NET utility to communicate with a GMail Calendar and I do the authentication like this:

Private Function DoAuthentication(ByRef rStrToken As String, ByRef rParameters As OAuth2Parameters) As Boolean
    Dim credential As UserCredential
    Dim Secrets = New ClientSecrets() With {
        .ClientId = m_strClientID,
        .ClientSecret = m_strClientSecret
    }
    'm_Scopes.Add(CalendarService.Scope.Calendar)
    m_Scopes.Add("https://www.googleapis.com/auth/calendar https://www.google.com/m8/feeds/")

    Try
        credential = GoogleWebAuthorizationBroker.AuthorizeAsync(Secrets, m_Scopes,
                                                                 "user", CancellationToken.None,
                                                                 New FileDataStore("PublicTalkSoftware.Calendar.Application")).Result()

        ' Create the calendar service using an initializer instance
        Dim initializer As New BaseClientService.Initializer() With {
            .HttpClientInitializer = credential,
            .ApplicationName = "GoogleCalIF"
        }
        m_Service = New CalendarService(initializer)

        rStrToken = credential.Token.AccessToken.ToString()
        rParameters.AccessToken = credential.Token.AccessToken
        rParameters.RefreshToken = credential.Token.RefreshToken
    Catch ex As Exception
        ' We encountered some kind of problem, perhaps they have not yet authenticated?
        ' Can we isolate that as the exception?

        Return False
    End Try

    Return True
End Function

So what I am asking is if they is a similar way that I can do the authentication bit myself so that I can just pass the token needed into the mailman object?

Thanks.

Hello Everybody! I use Delphi 10. My MySQL server use UTF-8 codepage, I try execute AES_ENCRYPT function and CkCrypt2mySqlAesEncrypt, but I get various results, because the CkCrypt2mySqlAesEncrypt function uses the ANSI encoding. When decrypting CkCrypt2mySqlAesDecrypt, I get only the question marks. How to implement AES-128-CBC crypt like MySQL AES_ENCRYPT with UTF-8 encoding? I could use CkCrypt2encryptStringENC, but I dont know which IV parameter uses AES_ENCRYPT.

Bug in Chilkat.HttpRequest Content-Length?

Hi.

I'm not sure what's the exactly problem here but I think it has something to do with the Encoding. I've used Firefox and the .NET Framework built-in HttpRequestMessage and both tell me that the Content-Length for this form data is 7 but Chilkat will make 9 out of it. Probably because of the "%20" space encoding. But if I send 9 to the server, he will reject the request.

 static void Main(string[] args)
    {
        // Set up some things
        const string logFileName = "log.txt";

        var url = new Uri("http://www.example.net/");

        var formData = new Dictionary<string, string>
        {
            ["space"] = " ",
        };

        // .NET Framework
        var request = new HttpRequestMessage(HttpMethod.Post, url)
        {
            Content = new FormUrlEncodedContent(formData)
        };

        File.AppendAllText(logFileName, $"Content-Length: {request.Content.Headers.ContentLength}");

        // Chilkat
        var http = new Http {SessionLogFilename = logFileName};
        http.UnlockComponent("test");

        var chilkatRequest = new HttpRequest
        {
            HttpVerb = "POST",
            ContentType= "application/x-www-form-urlencoded"
        };

        foreach (var pair in formData)
        {
            chilkatRequest.AddParam(pair.Key, pair.Value);
        }

        var response = http.SynchronousRequest(url.Host, 80, false, chilkatRequest);

        // See both results
        Process.Start(logFileName);
    }

GetFile fails, but file downloaded successfully; wrong expectedByteCount; right downloadedByteCount

I've upgraded my ftp2 activex control at the last version in last days; during my tests in some case I had some GetFile error message that with earlier version I did not have; there were messages like the one following. As you see: 1) Xml report says that "226-File successfully transferred" 2) Xml report says that "<downloadedbytecount>43</downloadedbytecount>" 3) Xml report says that "<expectedbytecount>325985</expectedbytecount>" so it seems that this error is about "<error>Downloaded byte count less than expected byte count.</error>" 4) But if I call Ftp.GetSizeByName, I've exactly the dimension corresponding to "<downloadedbytecount>" Have you ever find siyuation like this? Thank you

Anyone can help me to convert "php encryption" to "powerbuilder" using chilkat??. below the code that i want to convert

// Encryption Function =========== function mc_encrypt($data, $key) { /// make binary representasion of $key $key = hex2bin($key);

/// check key length, must be 256 bit or 32 bytes if (mb_strlen($key, "8bit") !== 32) { throw new Exception("Needs a 256-bit key!");}

// create initialization vector $iv_size = openssl_cipher_iv_length("aes-256-cbc"); $iv = openssl_random_pseudo_bytes($iv_size);

/// encrypt $encrypted = openssl_encrypt($data, "aes-256-cbc", $key, OPENSSL_RAW_DATA, $iv );

/// create signature, against padding oracle attacks $signature = mb_substr(hash_hmac("sha256", $encrypted, $key, true),0,10,"8bit");

/// combine all, encode, and format $encoded = chunk_split(base64_encode($signature.$iv.$encrypted));

return $encoded; }

// Decryption Function ========== function mc_decrypt($str, $key) {

/// make binary representation of $key $key = hex2bin($key);

/// check key length, must be 256 bit or 32 bytes if (mb_strlen($key, "8bit") !== 32) { throw new Exception("Needs a 256-bit key!"); }

/// check signature, against padding oracle attack $calc_signature = mb_substr(hash_hmac("sha256", $encrypted, $key, true),0,10,"8bit");

if(!mc_compare($signature,$calc_signature)) { return "SIGNATURE_NOT_MATCH"; /// signature doesn't match }

$decrypted = openssl_decrypt($encrypted, "aes-256-cbc", $key, OPENSSL_RAW_DATA, $iv);

return $decrypted; }

Chilkat SSH commands shows in output

Hello, I would like to get rid of the commands I am executing on device. I have Windows user form and when I am sending commands to the switch in the output except the results or action which the application did on the device I also see commands / config. I want to get rid of them and show only result of these commands.

            /*THIS IS THE SET OF COMMANDS I WANT TO RUN */
            ssh2.ChannelSendString(channelNum, command, "ansi");

            if (success != true)
            {
                if (x < 2)
                {
                    output_box.Invoke((MethodInvoker)delegate
                    {
                        // Running on the UI thread
                        output_box.Text += "\r\n Execution of commands failed \r\n Running again ...\r\n";
                        tofile += "\r\n Session failed \r\n Running again ...\r\n ";
                    });
                    x++;
                    i--;
                    continue;
                }
            }

            ssh2.ChannelSendEof(channelNum);
            var cmdOutput = ssh2.ChannelReadAndPoll(channelNum, 2000);
            var result = ssh2.GetReceivedText(channelNum, "ansi");
            tofile += result;

            output_box.Invoke((MethodInvoker)delegate {
                // Running on the UI thread
                output_box.Text += result;
            });

So what I see in the output_box is this -> how do I get rid of the first four lines starting with ,,conf t" and ending with ,,end"

############### SWITCH ##################### - 1 of 2

conf t
vlan 20
name 20
end

SWITCH# conf t

Enter configuration commands, one per line. End with CNTL/Z.

SWITCH(config)# vlan 20

SWITCH(config-vlan)# name 20

SWITCH(config-vlan)# end

Problems with AddRelatedFile2

I'm trying to send emails with a signature, it's a JPG file, and I want to embed in email foot.

I'm writing one cid in Html code img src='cid:Signature'

And after I make ::oMail:AddRelatedFile2( cSignatureFile, "Signature" )

However the email is received, the file is attached, but there is a "missing image" block in the body where the image is supposed to be in the body of the mail?

Wath's the problem.

Thanks.

How can the relative addressing work? Assuming the example is correct... or what else could be wrong?

Thanks!

I am attempting to connect to RaspberryPi 3 Windows 10 IoT which is running ftpd. I can connect to it using Filezilla without any issues. I installed the latest from NuGet in Visual Studio 2017 Enterprise.

Below is the sample code I am using to attempt to connect. It fails at ftp.ConnectAsync() with:

Should I be checking something else? Ex BgPercentDone
