Implement missing functions

[quantum]

Many missing functions compared to AutoIt for working with binary, memory stuff.

DllCallAddress, no such currently function right now in AHK.

DllCall() wrote:

This parameter may also consist solely of an integer, which is interpreted as the address of the function to call. Sources of such addresses include COM and RegisterCallback.

VarSetCapacity(var) will return its length

- DllCallAddress: DllCall supports an address.
- Binary: (I have written a function for hex to binary data called JEE_HexPut.) [On my wish list as 'StrPut' or 'HexPut'.]
- BinaryMid: 2-liner. AHK v1 cannot return a binary variable from a function, AHK v2 can, hence a possibility is preparing some space via VarSetCapacity, and then using NumPut/StrPut/memmove (Winapi)/RtlMoveMemory (Winapi). [Related: my wish list mentions 'BinCopy'.]
- BinaryLen: VarSetCapacity with no parameters is similar, but not the same. Giving the capacity rather than the size. [lexikos mentioned something similar in 'v2-thoughts', on my wish list as 'VarGetSize' / 'SizeOf'.]
- BinaryToString: StrGet.

- In general it's interesting to hear of things that AutoIt has that AutoHotkey doesn't. I'm working on a general library at the moment which has solutions of some kind for everything above except 'VarGetSize'.
- I noticed that AutoIt really lacks in terms of operators.

Right. So how do we get this kind of functionality in AHK v2?

And of course this. Now this is not the same as embedding it as a resource.

- You can store the function as a hex/base64 string, and convert it to binary data (via NumPut or CryptBinaryToString (Winapi)), and pass the address to DllCall.
- There's also an MCode function that's commonly used. There's a version of it here:

- Btw I would welcome anybody else to expand on anything that I've said on this thread.

What if the C++ machine code has external calls? Such as WINAPI?

[jeeswg]

- I haven't tried to do that. I only use a handful of machine code functions for the quick reading/writing of bits/bytes. I'd use DllCall for calling Winapi functions.
- Can't you just use TDM-GCC or do something similar to what AutoIt does? What does AutoIt do?
- Btw if you have any comments re. the pros/cons of AutoIt/AutoHotkey, I would be interested to hear. You can be completely honest, I feel that both have their plus points. I'd been investigating it myself, considering writing functions in both languages to complement the other. Any other missing functions? Cheers.
- The one thing I'd like that I've seen in AutoIt is the greater support for FASM.

[quantum]

Like I said will this work?

#include <windows.h>
void main()
{
MessageBox(0, "Hello", "Welcome Message", 1);
}

[jeeswg]

- (I meant to say more clearly above, I've only tried to compile pure C++ code, never with any Winapi functions.)
- I tried with MCode4GCC but it didn't work, if someone who's tried using MCode4GCC to compile C++ code with Winapi functions could chip in.
- It output some code, created without errors, but when input into the MCode function, and run via DllCall, it did nothing.

- You might try using the FASM approach, if you're familiar with it. But it's not too well documented.
