Auto-release Pools and Background Threads
Regarding Objective-C programming for MAC OS X and IOS: (from https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/MemoryMgmt/Articles/mmAutoreleasePools.html ) Cocoa always expects there to be an autorelease pool available. If a pool is not available, autoreleased objects do not get released and your application leaks memory. If you send an autorelease message when a pool is not available, Cocoa logs a suitable […]
Linking “C” Programs with the Chilkat C/C++ Libs
The Chilkat C/C++ libs are (internally) written in C++. Therefore, when linking a “C” program with the Chilkat libs, the C++ runtime libs must be included. This is true regardless of the operating system, whether it be Windows, MAC OS X, IOS, Linux, etc. Different build environments will have different ways of accomplishing the task. […]
Chilkat Customer App in Apple App Store
Question: Will using Chilkat (for IOS) prevent my app from being accepted into the Apple App Store? Answer: Using the Chilkat libs for IOS does not prevent it from being accepted in the Apple App Store. For reference, the following app uses Chilkat and was accepted into the app store on 14-March-2012. http://www.bouncemyx.com/
(C++) Return Email Headers as iso-8859-15? (or any other charset)
Question: In C++, is it somehow possible to specify a desired charset (like ISO-8859-15) when getting mail headers with POP3? Answer: Instead of calling the method that returns a “const char *” — which can return either utf-8 or ANSI (see this Chilkat blog post about the Utf8 property common to all Chilkat C++ classes), […]
SFTP vs. FTPS
Clarification on the acronyms “SFTP” and “FTPS” “SFTP” is the Secure File Transfer Protocol over SSH. It is a protocol unrelated to the FTP protocol. (It is actually a subsystem of SSH.) The Chilkat SSH / SFTP component is used for “SFTP”. SFTP is achieved by connecting to an SSH server at port 22. On […]
Unzipping zips with Unicode Filenames
Question: I see your example code includes the ability to create a zip with Unicode filenames. Does your product support unzipping files with unicode filenames, such as Chinese? Answer: Yes, it can unzip files w/ Unicode names — assuming the .zip was correctly created. Your first test should be to unzip without trying anything differently. […]
Debugging SshTunnel
The Chilkat SshTunnel object/class (may be “CkSshTunnel” in some programming languages) provides a number of properties to help in debugging (i.e. understanding) what is happening in the background thread: AcceptThreadSessionLogPath: May be set to the path of a log file that the SshTunnel will create and log activity regarding connections accepted. This will allow you […]
Delphi: how to call ActiveX Functions that return an OleVariant containing a Byte Array
Some Chilkat ActiveX functions return binary data as a Variant containing a byte array. If the Chilkat function fails, it returns an OleVariant containing an empty byte array. The following code snippet is incorrect and will cause Delphi to raise an EVariantBadIndexError exception if an empty OleVariant is returned. // This is incorrect: mybuffer : […]
IOS / Mac OS X Link Problems involving symbols such as __ZTVN10__cxxabiv121__vmi_class_type_infoE
If linking produces undefined symbols involving the following: __ZTVN10__cxxabiv121__vmi_class_type_infoE __Znwm __ZdlPv ___gxx_personality_sj0 ___cxa_begin_catch __ZTVN10__cxxabiv120__si_class_type_infoE ___cxa_end_catch __ZdaPv __ZTVN10__cxxabiv117__class_type_infoE etc. It means you’re NOT linking with the C++ runtime libs. To link with the C++ runtime libs, include an empty source file having a file extension of “.cpp”. For more information, see the IOS Objective-C linking notes
regsvr32 Error Code 80070005
The error code 80070005 usually means that you do not have enough permission to write to the registry. See this Chilkat blog post ( How to Register an ActiveX DLL using regsvr32 ) for help in running regsvr with administrative privileges.
