Question: We are trying out the FTP2 ActiveX component for ASP. What we need to do is have people be able to upload files to the web server over the Internet. Is this component able to do this – or can it only FTP files that are already on the web server? Answer: This is a common question. The need […]
Question: Our problem that in the POP3 incoming account there are 400 mails but the developer’s UIDL query can see only the first 251 mails and downloads only 251 mails. Answer: There may be several common reasons. The first thing to do is to verify number of emails in the mailbox by calling the mailman.GetMailboxCount method. It sends a STAT […]
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 […]

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. To get more information, Google “Ms-Exch-SMTP-Submit permission”… <ChilkatLog> <SendEmail> <DllDate>Mar 6 2009</DllDate> <UnlockPrefix>anything for 30-day trial</UnlockPrefix> <Username>***</Username> <Component>Java</Component> <Recipients> <NumTo>1</NumTo> <To>***</To> <NumCC>0</NumCC> <NumBCC>0</NumBCC> </Recipients> <info>Need new SMTP connection</info> <SMTP_Connect> […]
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 […]
