In rare cases, an email’s MIME might be structured in a way that is highly unusual and doesn’t follow conventions. In other words, the nested MIME structure of an email should follow conventions that make it possible to semantically understand the purpose of each MIME part — such as an attachment, or an image to be included in the HTML […]
The “client credentials” OAuth2 flow is allowed by many REST API’s for the case where a program is running in a non-interactive environment. It’s simply an HTTP POST where the client_id and client_secret are sent, and the OAuth2 access token is returned. If you have a sample CURL statement that demonstrates how to do it, you can generate Chilkat source […]
If your application calls Chilkat’s SFtp.OpenFile, and it fails because the server responded with SSH_FX_NO_SUCH_FILE, it means the file does not exist on the server. Trust that this is correct — the server would not say so unless the remote file truly does not exist on the server at the path your application provided. All remote file paths passed to […]

Chilkat does not provide functionality for XML-to-JSON conversion (or the reverse) because XML does not convert to JSON in an unambiguous way. XML and JSON have different structural and data modeling principles, leading to potential challenges and ambiguities during the conversion process. Some factors that contribute to the potential ambiguities are: Hierarchical vs. Flat Structure: XML supports deeply nested hierarchical […]
Question: I’m using the LoadPfxFile method of the cert object and it takes about 4 or 5 seconds in load the PFX certificate. On the other hand, if I sign the document using an installed certificate, it’s instantaneous. Why does LoadPfxFile take so much time? Is there a way to reduce the loadPfxFile time? Answer: When a password is used […]
There are a few different ways related images can be contained in the MIME of HTML email. The 1st is by Content-Location. The following MIME shows the use of Content-Location. The URL contained in the <img> tag’s “src” attribute should match the value of the Content-Location header. Content-Type: multipart/related; boundary=boundary1 –boundary1 Content-Type: text/html; charset=UTF-8 <html> <body> <p>This is an email […]
