I'm getting kinda serious about building a halfways decent dll for use with autoit.  things are going pretty smoothly HA so far.  I've had more successes than failures so not off to a bad start.

So in a nutshell I need to make the dll open a handle to the calling process console so i can print out     aaaa chicken nuggets well that was a setback... anyways you live and learn.  To the point of this thread.  I had previously attempted to wrap my brain around how to convert a hex number into a string that displays itself in hex.  Theres some operator overloads that take care of this in the streaming classes.  I had done this with base 10 numbers and converted them to a string which I thought was pretty cool that I figured out how to do that relatively pain free (been awhile i forget about the pain) but wouldn't you believe it i played around with this function for an hr ...had to shut my eyes and zen for a few min bc i couldn't believe it wasn't working.  I starting thinking about the numbers and their sizes, why hex is a thing and....it was like a slap in the face.  Its honestly so simple.  Its less complicated than doing a base 10 number to a string

void  handletostring (HANDLE msg) {
    int a = (int)msg;
    string s{};
    while (a) {
        int i = a % 16;
        s.push_back(i < 10 ? i + 48 : i + 65);
        a >>= 4;
    }
    cout<<stringreverse(s);
}

like duh right.  Regardless a good learning experience.  Happy new year.

Are you making your 2022 life harder than it should or is it me?

$h  = GUICreate("My GUI")
ConsoleWrite($h & @LF)
ConsoleWrite(_UintToString($h, 16) & @LF)

Func _UintToString($i, $base)
    Return DllCall("msvcrt.dll", "wstr:cdecl", "_ui64tow", "uint64", $i, "wstr", "", "int", $base)[0]
EndFunc   ;==>_UintToString

; Func _StringToUint($s, $base)

This is a far cry from the point of the project that i'm working on.  I was having problems writing to the autoit console and for some reason I was trying to get debug information to print to the autoit console and long story short I started down the rabbit hole of converting an int to hex.  when playing around in c and c++ doing conversions like this from numbers to strings and back happen somewhat regularly bc (especially c) theres not always a built in function to deal with it the way you want to and writing little utility functions does happen somewhat often.  Its also good practice and its alot more efficient that importing entire libraries everytime you want to convert and int to a char or something along those lines.  

I'm just happy to have figured out the logic.  I like building things that already exist from the ground up bc you learn alot about how things work and answers to why certain things are the way they are.  I was tired when I did this If i wanted to do it and easier way I could read the handle bit by bit from most significant end to the least and avoid reversing the string and other messing around.  I've since deleted this bc its unnecessary but i'm still happy I figured it out.
