Question: There is a possibility that the file to be deleted does not actually exist, so can I do a test first so that i only delete if it is present and thus avoid any nasty warning about missing files? Answer: The Chilkat components/libraries never pop up warnings or display error messages — they simply return success/failure status and provide […]
Question: Some of our users are reporting that the self-extracting file reports “Failed to extract file”. The user has admin access to the file system and the file is not corrupted. Answer: When running the self-extracting EXE, use the “-log” command line option to generate a log file with error information. If the reason for failure is not clear, send […]
This blog post describes the solution to a problem experienced by a Chilkat customer trying to open a .zip archive using the Chilkat Zip ActiveX component in COM+. His/her code worked in a typical application environment, but not in COM+. The error occurred when trying to open a large .zip. The solution was to enable compensation and 3GB support (see […]
Question: Hi, I’m extremely interested in purchasing the Chilikat SSH dll. Let me describe my situation: I have several host sites (approximately 70 of them) that allow me to connect to their SSH servers. All of these sites have a database server (sitting on the same server as the ssh server) accepting connections on port 1937. I have been successful […]
This just came to our attention. When sending email using Exchange Server, a Ms-Exch-SMTP-Submit Permissions problem seems like an incorrect login/password error. A sample of the Chilkat.MailMan’s LastErrorXml is shown below.

Explicitly setting the date/time for a file on the FTP server is not a well defined task w/ the FTP protocol. Some servers support the MDTM command. However, MDTM is officially for getting a remote file’s date/time. Some FTP servers allow for using MDTM to set a remote file’s date/time (even though this is not a standard). Some FTP servers […]
See the Python documentation for Modules. Specifically, scroll down to the section entitled “The Module Search Path” and “Compiled Python Files”. ( Although the information for locating modules is for Python 2.6, I believe the same information applies to Python 2.5 at Python 2.5.4 Modules Documentation )
If your application is using a pre-installed certificate for creating a digital signature, or for decrypting, then it needs access to the private key. (By pre-installed, we mean a certificate that has been imported from a PFX (or via the browser) into a Windows registry-based certificate store.) If you chose to enable strong private key protection, then the Windows operating […]
This C++ example demonstrates how to derive a class from the CkSFtpProgress base class to implement progress monitoring and abort for SFTP: // To monitor SFTP progress, derive a class from CkSFtpProgress and // provide implementations for AbortCheck and PercentDone: class MySFtpProgress : public CkSFtpProgress { public: MySFtpProgress() { } virtual ~MySFtpProgress() { } // Called periodically during any SFTP […]
The AbortCheck event is standard in Chilkat .NET classes that involve communications over sockets (FTP, POP3, SMTP, IMAP, HTTP, etc.) or time-consuming operations such as zipping/unzipping large files. There are three steps to using AbortCheck: 1. Enable event callbacks by setting the EnableEvents property = true. Chilkat.MailMan mailman = new Chilkat.MailMan(); mailman.EnableEvents = true; 2. Set the HeartbeatMs property. The […]
