well i am a long time vb/c/cpp code, mostly vb, and was wondering after looking at some c/cpp code how to port this statement to vb.net, with the .net framework.

code example:
CODE
...
typedef void SPELL_FUN args( ( int sn, int level, CHAR_DATA *ch, void *vo,    int target ) );  //declaration
...
SPELL_FUN * spell_fun; //usage
...


as well, i am trying to make a forward pointing structure statement, converted from the c/cpp code but having issues doing the conversion. if i can get this answered with a solution in vb instead of compiling into a DLL and making areference from there...would rather keep the code local to the app instead of a DLL inclusion.

To any mod/admin that reads this, it's a VB.Net topic!

VB.NET doesn't work well at all with pointers. The concept pretty much doesn't exist in the language. Even though it does have objects of type Int32Ptr which can be used for basic pointer operations, it won't be that useful to you for pointing to functions.

You could look into delegates though. A delegate can be associated with a function and by using the delegate you can pass around a call to a particular function. Much like passing around a pointer to a function.

But there is no direct equivalent. .NET has made tremendous strides to get away from pointers because it can lead to memory corruption and in .NET the framework handles much of the memory allocation and garbage collection.

Sorry. smile.gif

yeah i know that VB doesnt have pointers per say....about as close to pointers as VB gets is in functions when passing arguments with ByRef....but there is a comprable to the above statement just not sure if the venture would be worth it or if i should just leave it in C/CPP.
