Question: We are making a timed call to an FTP folder to check for new files. Once a file appears, we download it. Is it possible to keep the session open between these timed calls, or should it be closed and re-opened every time we check? The interval is very small 2 seconds, but may run for days at a […]
Question: I was wondering if the IMAP library for .NET allows me to go into an IMAP server, and change the body of a previous email? Is any email fair game? Or does it have to be in drafts? If so, is there a special way to save it to the server? If this does not work, can I delete […]
This post provides ASP.NET code (C#) to display an HTML email using the Chilkat .NET Email component. It will provide a live example, as well as a download link to the sample code and data files. This example is only concerned with displaying the HTML body of the email, including embedded images. Displaying the text header fields (Subject, From, To, […]
When linking with a Chilkat C++ library, you must choose the .lib that matches your project’s “code generation” property setting. For example, in VC++ 8.0, these are the Chilkat .lib’s: ChilkatDbg.lib ChilkatDbgDll.lib ChilkatRel.lib ChilkatRelDll.lib If “Dll” is in the library name, it means that you are *not* statically linking with the C runtime libs. Just because your project produces a […]
This new ASP Upload example demonstrates how to use the Chilkat ASP Upload component to receive uploads in ASP and save the received files to the Web server’s filesystem.
This post provides C# sample code for matching a test vector (known answer test). 3DES Settings: ECB Mode 192-bit key (i.e. 3 8-bit keys) ASCII Key Bytes: 1234567890123456ABCDEFGH ASCII Text to Encrypt: The quick brown fox jumped over the lazy dog Pads with zero bytes Hexadecimalized Encrypted Result: 13d4d3549493d2870f93c3e0812a06de467e1f9c0bfb16c0 70ede5cabbd3ca62f217a7ae8d47f2c7bf62eb309323b58b C# Code: string keyAscii = “1234567890123456ABCDEFGH”; byte[] key = ASCIIEncoding.ASCII.GetBytes(keyAscii); […]
This post provides PHP sample code for matching a test vector (known answer test). 3DES Settings: ECB Mode 192-bit key (i.e. 3 8-bit keys) ASCII Key Bytes: 1234567890123456ABCDEFGH ASCII Text to Encrypt: The quick brown fox jumped over the lazy dog Pads with zero bytes Hexadecimalized Encrypted Result: 13d4d3549493d2870f93c3e0812a06de467e1f9c0bfb16c0 70ede5cabbd3ca62f217a7ae8d47f2c7bf62eb309323b58b PHP Code: <?php $cipher = mcrypt_module_open(MCRYPT_3DES, ”, MCRYPT_MODE_ECB, ”); // […]
The POP3 protocol is such that a new session is started after a successful login. The session is a snapshot of the existing emails in the mailbox. Any new email that arrives during the session will not be seen until the session is ended (i.e. you logout) and a new session is started. Also, emails marked for deletion are not […]
Question: Very quick question for you about distribution. Is it a simple matter of just using this unlock code in the appropriate place in the code and adding a reference to the dll in my project? Or, do I need to include and run your MSI with the installation of my own application for all of my customers? Answer: You […]
The Chilkat FTP2 ActiveX has events for progress monitoring. The events may also be used to abort an FTP upload/download, or to skip files and/or directories. These are the events in Visual FoxPro terms: PROCEDURE _IChilkatFtp2Events_PutProgress(percentDone AS Number) AS VOID; PROCEDURE _IChilkatFtp2Events_GetProgress(percentDone AS Number) AS VOID; PROCEDURE _IChilkatFtp2Events_AbortCheck(abortFlag AS Number) AS VOID; PROCEDURE _IChilkatFtp2Events_BeginDownloadFile(filePath AS String, skipFlag AS Number) AS […]
