Hi,

I have a project that requires a lot of manipulation of a very big string (100k or more).

In AHK this is slow (about 10 secounds) each time.

I am considering doing this processing in C++.

Please has someone a step by step example of how to

1) create a simple DLL in C++ (i.e. just accept a string, change it slightly and return it).
2) how to call this DLL from AHK passing to it a string parameter (perhaps a really big string).
3) get hold of this changed string from AHK into a AHK variable.

What kind of manipulation? Maybe your current method is inefficient.

I'm scanning a very big string and putting in rich text format commands depending on what is in the string. Stringreplace commands won't do what i'm after. Due to what I have to do there is no choice but to scan each character and manipulate the string programmatic ally, hence the need for a C++ dll.

Have you tried using RegEx? It's written in C.

Here is a link to a step-by-step guide/tutorial to creating DLL's in C++. Creating And Using DLLs

Thanks for that,

But what I was really looking for was an example of AHK passing a parameter string to a dll. Doing somtething with that string in the dll and returning the string back through the parameter to AHK. Preferrably an example calling the dll with AHK and the dll programmed in c++ express.

The example above just outputs to the console.

I know I may be expecting a lot, but as much as I have tried, I have been so far unable to achieve this.

Someone please please help with an example of this, please.
