C++ CkHttp AbortCheck Callback

Chilkat classes that involve network communications can use callbacks. This blog post describes the CkHttp AbortCheck callback. An application can request periodic AbortCheck callbacks according to the HeartbeatMs property setting. (If HeartbeatMs = 0, then no AbortCheck callbacks will occur.) For example: // Create a class that inherits CkHttpProgress and override desired methods.. class MyHttpProgress : public CkHttpProgress { public: […]

The samples are extremely helpful, and make it easy to implement the call in any programming language. With Chilkat, you can usually generate sample code by pasting the sample request, and the body of the sample response into Chilkat’s online tool […]

More Microsoft Graph Misc Notes

Relaying more shared information: “I also wanted to notify you that the “profile” can also be extracted without the use of Graph API (User.Read): https://learn.microsoft.com/en-us/azure/active-directory/develop/id-tokens id_token contains that information and is given along with the access_token but it has to be decoded from a JWT (https://en.wikipedia.org/wiki/JSON_Web_Token) openid, profile, email and offline_access are like some kind of “universal” scopes which can be […]

Question: My question is regarding the SharedLib when initializing pkcs11 module.

Answer: This is a good question. On a non-Windows system, Chilkat would need to communicate with the […]
