Question: I have done some Dataflex development for the UK ‘Making Tax Digital’ functions that require oAuth2 authorisation. I’ve used your example code for the Windows work but I now need to get this working for a Dataflex Web based version. That communication part will all take place from the Web server. Any pointers on how to get oAuth to […]

I had to turn on “allow access for less secured apps” for that Gmail account but otherwise, I am able to get everything working. However, after some weeks of inactivity, Google would automatically turn disable access for less secured […]

The Chilkat Xmp class provides the abililty to insert/update/remove/extract XMP metadata from JPEG and TIFF image files. In addition, the XMP API provides helper methods to make it easier to construct XML according to XMP specifications. These methods are usually sufficient, but may lack flexibility to create more complex XMP metadata. An alternative approach is to use Chilkat’s online code […]
Problem: I was using Chilkat to sign xml messages, very similar to one of your examples: https://www.example-code.com/dotnet-core/fatturapa_cades_bes.asp The code was deployed as an Azure V2 function written in .Net Core 2.2 It worked without problems for months, but then after one deploy last week it started crashing on the line: new Chilkat.Global().UnlockBundle(ChilkatKey); It works locally, and only fails in production […]

A different thread pool is used for each device communication, so they do not block each other or the main thread. Because of the issue earlier, I am using the same http object for all communications. Most of the requests are very quick (~ […]
