Could not load file or assembly ‘ChilkatDotNet4.dll’ or one of its dependencies.
(Thank you Josh for your helpful information!) “I see that occasionally information from clients (with the client’s permission) end up on the blog and thought that perhaps this one would qualify. If there is mention of the C++ Runtime, I didn’t find it. At any rate, I was having trouble getting the ChilkatDotNet4.dll to load. […]

CodeGear C++ Builder: Passing Strings to COM / ActiveX Methods
The correct way to pass a string to a COM/ActiveX method is to use “WideString (theString).c_bstr()” because ActiveX controls/components require BSTR’s, and not strings. BSTR’s are wide strings (Unicode) where the length of the string precedes the string in memory. The C++ Builder code to pass a string to an ActiveX function is as follows: […]
PercentDone callback counts as an AbortCheck
Question: “I’ve got the Chilkat C++ libs linked with my project, and am using the HTTP classes successfully. One thing is confusing me, though. I’ve derived a class from CkHttpProgress.h and overridden AbortCheck(…) to provide cancellation support. However, AbortCheck(…) never gets called.
