Chilkat SSH – SendReqExec vs SendReqShell
Chilkat’s SSH class provides the ability to start a shell session by calling SendReqShell, or by calling QuickShell. You can alternatively run a single remote command by calling SendReqExec. SendReqExec does the “exec” command, whereas SendReqShell (or QuickShell) starts an interactive shell session where bytes sent to the SSH server via methods such as ChannelSendString […]
Unlock Chilkat at the Start of Each ASP Page
In Classic ASP, if you want to run the same code at the start of each web page, the best approach is to create an include file containing the code and then include that file at the beginning of each page. This way, you can centralize the code and ensure it runs on every page. […]
Explaining the Concept of Folders in AWS S3
In AWS S3 (Simple Storage Service), the concept of folders does not exist in the traditional sense as it does in a typical file system. Instead, S3 is a flat storage system where all objects (files) are stored in a single, global namespace. However, AWS S3 simulates a folder-like structure through the use of object […]
Background Threads (Async) in Classic ASP
* Chilkat recommends avoiding the use of Async methods in Classic ASP. In summary, the Chilkat Async methods run in a background thread (within Chilkat) and you don’t want the background thread to be running after the processing of the ASP page is completed. In Classic ASP, creating and managing background threads is not natively […]
HTTP GET Works in Browser but not in Application

If so, then for testing purposes, temporarily turn BIC off, and try again. The Browser Integrity Check (BIC) feature in Cloudflare is a security […]

Avoid Non-usascii Literal Strings in Source Code
It’s generally not a good idea to use literal strings containing non-usascii chars in your source code, regardless of programming language. For example, in C++ a literal string would be like this: const char *s = “44ης Οδός, αρ.2”; Or perhaps in another programming language, such as DataFlex, it looks like this: Move “44ης Οδός, […]
GMail OAuth2 Scope for SMTP vs REST API
There’s confusion about the OAuth2 scope required to send email via GMAIL. There are two ways to programmatically send email using your GMail account: Connecting to smtp.gmail.com using the SMTP protocol (i.e. using Chilkat.MailMan) Calling the GMail REST API over HTTPS using Chilkat.Http or Chilkat.Rest. The scope for IMAP, POP, and SMTP access is […]
