The interface you get there is quite low level, mapping rather directly to GDI+ (i.e. a C++ interface). If we had more time we could clearly "raise" the interface to a higher level. Let us start by considering what kinds of data we are dealing with, by considering a couple of the propertie...

Yes.

bitmap and image in the gdiplus package supports many formats, but they are (of course) used in a different way.

Yes, class facts are shared between all threads. Yes, memory allocated by memory::allocAtomicHeap is not scanned for pointers but is itself subject to garbage collection. If an object is shared between threads the the corresponding object facts are also shared between the threads (through the objec...

Perhaps "Windows VPS hosting" (Virtual Private Server) can do the job.

But then you should (to some extend, depending on the deal) be prepared to install and configure stuff yourself. In that context you should consider whether the VPS will need a SSL certificate (such one has a price).

See WEB services and the webService examples in the Commercial Edition examples.

I am afraid that it is long time since we have tested this. It will work if you change the last part of the "hanoi.pro" file like this: constants docBegin = @'Content-Type: text/html; charset=UTF-8 <!DOCTYPE html> <html> <meta http-equiv="Content-Type" content="text/html; ch...

It has been renamed to 'iXMLDOMNode', i.e. without '_import'.

However, on a web provider your program will have to be web in some way,...

Perhaps it is simpler to find a provider that offers a Windows environment. Regarding 2. I think it says that is should be runnable without requiring any g...

It seems that the file is in the "exe" directory, but the program looks for the file one level above. Hence the two dots in the error message ..\fa.txt

We do not provide an automatic unit test facility. In the commercial edition there is a (relatively simple) testSupport package that can be used for when writing tests. The package mainly has to do with "standardizing" the output from a test program. But I am afraid that you will have to u...

Strange it does for me. Which browser do you use?

I do not understand what you mean?

Hi, Altur. I think your reasons for wanting the old version are reasonable, but at the same time they are conflicting with our wish about supporting people on as few versions as possible and preferably the latest. Besides this we also believe that our product is getting better and better. I have you...
