How to Deploy ActiveX Components with your Application
A link to a Chilkat blog post within information about ActiveX DLL deployment: http://www.chilkatsoft.com/p/p_395.asp
A .NET Assembly is *not* an ActiveX. It is not registered via regsvr32.
Question: I have now tried to register the component manually, but then I get his message: “The module c:\…\ChilkatDotNet2.dll was loaded but the entry-point DllRegisterServer was not found. Make sure that c:\…\ChilkatDotNet2.dll is a valid DLL or OCX file and try again.” Answer: A .NET assembly is not an ActiveX component. It is not registered with regsvr32. If your application […]
Modify Email on IMAP Server?
Question: I was wondering how it would be possible to make changes to an email on the server. Answer: Once an email is on a server, it cannot be modified. This is not a Chilkat limitation, but it’s the way mail servers work. However, with IMAP you may download an email, make changes, upload the new email to the mailbox […]
Socket Programming – “Must-Know” Concepts

Windows Application User-Interface Freezes?
Question: I recently purchased the Chilkat HTTP component and am using it with a Visual FoxPro application. However, each time I run it the form freezes and I get the Not Responding message in the title bar. I have an animated GIF that I am using as a quasi-progress meter but that freezes as well.

FTP MLST command?
Question: A quickie question about the FTP2 control. I have some clients with strange FTP servers that return the directory listings in formats that no control seems to be able to handle (although I have not tried yours!). However, it is next to impossible to test, since I do not have access to their server. For them, we use the […]
Using Chilkat in Managed C++

A Managed C++ application (using Microsoft’s Managed Extensions for C++) runs within the .NET Framework and therefore must use the Chilkat .NET assembly. The Chilkat C++ online reference documentation and online examples are for unmanaged C++ applications. For Managed C++, the best choice is to read the C# online documentation […]
IMAP – Search for Messages by Message-ID or any Email Header Field
Using the Chilkat IMAP API: To download emails having the exact contents of a header field, or all emails where a given header field contains a specified substring, use the Search method like this: (C++) CkMessageSet *mset = imap.Search(“HEADER Message-ID 48208D0C”,true); (C#) Chilkat.MessageSet mset = imap.Search(“HEADER Message-ID 48208D0C”,true); If the Search method returns a non-NULL message set object, then download […]
Saving an RSA key pair to a file
Question: I’m having trouble finding a good/complete VB.Net Chilkat example of how to generate an RSA key container with a key pair (private and public) and save that key container to a file. Answer: I think I can clarify. With 2 points: 1) In actuality, an RSA private key also contains the public-part of the key. It contains the all […]
Delete Files from a Zip Archive
Question: “I’ve been trying out the ZIP package that you guys have and for the most part it’s great. I do however have a question about folder manipulation. What I would like to be able to do is individually remove files from the zip and if the directory is empty I would like to remove the directory from the zip […]
