Hi

New to ChilKat but hoping someone can help - I am probably doing something dumb

If I use imap.search with "ALL" as a criteria then it works fine and I can loop through the messageset and get all the info for the various emails. If however I try and be specific using SUBJECT or HEADER <field> or TEXT (or anything other than ALL) then it returns 0 messages - so in ALL I can show the subject (for example one email has a subject of Hello and I see that in the returned messageset for ALL) but if i then search SUBJECT Hello it returns 0 messages (and any other criteria does the same) - any help or thoughts appreciated! - its 9.5.0 32 bit via VBS - working ALL, non working Hello and lasterror shown below.

Not Working searchkey = "SUBJECT Hello"

          Set messageSet = imap.Search(searchkey,1)

Working searchkey = "ALL"

         Set messageSet = imap.Search(searchkey,1)

Hello,

Trying to run the encription c++ example for hash. https://www.example-code.com/cpp/crypt2_md5_hash_file.asp

I created a project in MSVC 12 and added the include and lib for the crypt download from your site. I also add libs to link with to to the project crypt32.lib and advapi32.lib

Where did I go wrong ...?

I get the following errors. Assume I am missing an library to link with ...

Thanks!

How to create a ssh tunnel by setting the parameter -C that compress the data?

Hi,

i have a problem trying to connect with SSH. i am able to connect to SSH via the local terminal using "ssh <user>@<ipaddress> -i <privatekey>"

but when i try to connect externally i get the error below

do you guys have any idea where i have to look to solve this?

my knowledge about this is pretty limited and google has not yet helped.

Since we have a 'go live' clearence from MS we can redist VC++ project built with latest RC, but we need the static linked lib. Do you have scheduled a release for this compiler ?

TIA

Hi

I have been having problems using the QuickAppend zip function to append the contents of a new zip file to an existing one.

I've tried this with the node, python and .Net (via a colleague) versions of Chilkat, on Mac, Linux and Windows (via colleague) machines. Whichever combination I try, I seem to always end up with a zip file which has extra bytes in it. The zip file cannot be extracted using many zip tools (eg. command line zip tools, and we've also tried native Mac and PC tools to extract)

I have followed the example code exactly and am using very simple example text files and zip files to test.

I have recorded a screencast to show exactly what I'm doing and what happens. The error seems to be that there is extra data in the zip that shouldn't be there (eg. "Entry after central directory found"):

https://drive.google.com/a/tomkerswill.co.uk/file/d/0B6S93W7cxOpHdWZmUWEtRERMRXc/view

Note - I put in a forum post in April ( http://www.chilkatforum.com/questions/10132/quickappend ), but rather than resurrect that dead thread, I thought it was better to create a new one.

Is there a way to use your free component (or other) to upload a large file as binary data stream from a file to a https service whithout big memory consumption? ActiveX/Classic ASP

Thank you

Werner

I use CkZip C++ v9.5.0.58 in an application that runs on Windows. This application uses CkZip to store large numbers of small jpg files, so no compression.

Performance is important and so I have always used QuickAppend when adding new files to existing zip archives.

I am finding that when we use QuickAppend to add a small file (for example 2KB) file to a zip containing many (for example several thousand) similar small files, the file grows by an amount significantly larger than the added file.

I believe what is happening is that the central directory at the end of the existing zip file is large due to the high count of files in the zip. When the central directory is larger than the data being added, the new data only partially overwrites the old central directory. The new central directory is then appended to the end of the zip, leaving a large remnant of the old central directory. This repeats for each new added file, compounding the problem. We are seeing zip files that are 3 or 4 times larger than all the constituent files. This is bad for us because one of the reasons for using zip is to efficiently pack the files for optimal file-system storage.

If I have understood the problem correctly, is it possible to make QuickAppend add the new central directory to the end of the new file entry segment rather than at the end of the file? When adding a new file, the new central directory will always be larger than the previous one, ensuring that the old data is completely over-written, leaving the end of central directory record correctly at the end of the file.

Has anyone else seen this problem and found a solution?

I can supply an example zip file showing the problem if needed.

Hello, I am unsure how to correctly load a pem file I generate and saved to disk. I want to load the public key, encode a string and load the private key from another pem file to decrypt the string. I did try with LoadPem as no Password is given, but can not get it to work.

I am currently generating and writing the pem files as follows (works very well):

<?php
include("chilkat_9_5_0.php");

$rsa = new CkRsa();

$success = $rsa->UnlockComponent("using my key");
if ($success != true) {
    print 'RSA unlock failed' . "\n";
    exit;
}
$success = $rsa->GenerateKey(2048);
if ($success != true) {
    print $rsa->lastErrorText() . "\n";
    exit;
}

$publicKeyXml = $rsa->exportPublicKey();
print "public: ".$publicKeyXml . "\n";

$privateKeyXml = $rsa->exportPrivateKey();
print "private: ".$privateKeyXml . "\n";

//  Save the private key in PEM format:
$privKey = new CkPrivateKey();
$success = $privKey->LoadXml($privateKeyXml);
$success = $privKey->SaveRsaPemFile('privateKey.pem');

//  Save in PEM format
$pubKey = new CkPublicKey();
$success = $pubKey->LoadXml($publicKeyXml);
$success = $pubKey->SaveOpenSslPemFile('publicKey.pem');

?>

Using FileZilla, I do have to click through a warning box stating that the server's host key is unknown - Is that the error SFTP is running into? If so I need to bypass it - I trust the site

Thoughts?

Hi,

I have copied pasted text from https://www.example-code.com/sql/mht_emailWebPage.asp

But I get a blank email..

Please help!

I've been creating a Self Extracting Zip using Zip-2-Secure-Exe, and I quite like the program. But I do run into a particular problem: it seems that overly large files throw errors when they are being zipped.

I've been trying to zip up all of the Runtimes that my setup file will use alongside my setup file, but one of them (about 80 MB) always throws this error:

appendToSimpleArchive:
WindowsError: The process cannot access the file because it is being used by another process.
failedToDeleteFilepath: .\ckz_6G8N.tmp
--appendToSimpleArchive
Failed to append Nth file/directory to EXE.
fileOrDirName: Runtimes/32 bit/CRRuntime_32bit_13_0_11.msi

Is there any limitation on file size that is getting in the way, or is it something else entirely?

Hello,

We are planning to use bcrypt in our next multiplatform (php, c#, cocoa/swift) application. Is it supported by Chilkat? I did not find it in the references.

It is possible to write the code without Chilkat but it would be very good (and easy) to use the same code all in the applications.

Thank you!

Have a really good working version of AES and RSA keypairs with Chilkat. However we'd like to implement new keys based on ECC keys.

We've got nice and fast working examples of ECC creation and can generate the PEM's for Priv/Public keys.

However i can't see any examples of using these for encryption AES keys or encryption? Could someone share some examples if possible?

Quoting the CkSocket C++ Reference Documentation (here):

TCP socket component with SSL capability. Supports both asynchronous connect, accept, send, and read operations in all programming languages. The ActiveX and .NET socket components also include heartbeat, completion, and other events when blocking methods are called. DNS and reverse DNS is support in both synchronous and asynchronous modes. Supports the ability to abort all operations: connect, accept, send, receive, DNS lookups, etc. prior to completion.

However, I don't see any Reverse DNS methods listed in the documentation. Is reverse DNS lookup supported or am I missing something?

Hi,

Downloaded files from one of our operators are always empty. I have tried active/passive modes, GET/MGET, ascii or binary to no avail. What is curios is that I can download the files from command prompt!

Currently I use ChilkatAx-9.5.0-win32.dll version 9.5.0.64.

Has anybody else had the same problem?

Thanks,

Dan

I’ve noticed that when choosing not to download attachments when requesting an IMAP email, calling GetEmailNumAttach returns the incorrect number of attachments. If an email has no attachments then the number returned generally seems to be 2. The attachment information stored within the eml file itself appears to be correct.

Also, as the attachment information is stored in the eml data, is there a specific reason why this information is acquired via the CkoImap object and not through the CkoEmail object directly?

I’m using the latest iOS libraries (v9.5.0.51).

Language: Visual Foxpro Controls: Chilkat_9_5_0.MailMan And Chilkat_9_5_0.Email

With these controls i solved many problems with SSL and TLS post office systems, but now i have a problem sending mail with a server with no authentication and no security protocol....simple on port 25 (seems so)...

This is the error message i receive:

Does you C++ implementation have a tool to ask the current memory usage by you components?

I have a situation where I fetch about 1 MB of data from a database and feed it into the CkEmail component.

This results in an increase from 7MB to 300MB memory for the process in Windows.

So I would like to determine how much of this 300MB is from the Chilkat component and how much comes from my own code and/or other libraries.
