Wow! P/INVOKE made easy

While wasting tim^H^H^H^H^H^H^H^H^H ahem While reading important and interesting stuff around, I stumbled upon http://www.pinvoke.net/. It is a great site for those who want to P/INVOKE from .NET languages on native APIs. Heck, it’s so great sometimes I check it even when coding in native C++ :D

DevIL.NET 1.1 !

I’ve released DevIL.NET 1.1.
It’s a small update for a small library ;)

Code Snippet I : Wrapper for CLR string to native string marshalling

A frequent (too much frequent) need in Managed C++ is going from System::String objects to char* or wchar_t* strings. The boring side of the marshalling is that the memory allocated with the StringToHGlobalxxx functions should be freed with a matching call to FreeHGlobal.

The solution is simple : using the power of C++ destructors we can create a temporary object for the entire time we need the string. Whenever the object goes out of scope, the string is automagically freed.

You can find the code (released to public domain) here.

Please note that assignments (and copy-constructor) are disabled (they are in an empty private method) to preserve the destruction safety (the free is thus execute once and only once).

As an example you can do :

void mystrcpy(char* dest, const System::String __gc* source)
{
strcpy(dest, StringAutoMarshal(source));
}

with no need to manage the marshalling manually.

Another free book on the shelf

You can get a free copy of “.NET in Samples” ebook here.

The samples are all in C#, but I think the book can be useful for anyone using any .NET language.
