From here https://stackoverflow.com/questions/3454315/is-it-possible-to-pin-a-dll-in-memory-to-prevent-unloading
I use several UDFs on the Forum to do various things. Those UDFs work very well.
Effectively the UDFs are DLL wrappers, that make it possible to access DLL functions easily without the long hard slog of DLLCall() every time.
However, I have now run into the issue that multiple UDF DLLCalls are slow. Not mind numbingly slow, but slow enough to become noticeable with a large of repeated function calls.
So I was wondering, is it possible to "load a DLL into memory" and leave it there for the duration of my script's lifetime, avoid repeated DLL on-disk reads with a persistent in memory DLL?
From Microsoft
https://docs.microsoft.com/en-us/windows/desktop/dlls/about-dynamic-link-libraries
Looks like what I want to do is: load-time dynamic linking,
So next question, (a) how do I do this with AutoIt (b) How would this impact on standard AutoIt type DLL calls?
The point is speed. Is there a different approach?
Or am I barking up the wrong tree?

Hello,
i need help to translate the c code to autoit .
I don't understand the callback function.
#include <windows.h> #include <stdio.h> // native IR Data by PAnsiChar typedef void CALLBACK CallBackPAnsiChar(char*, char*, char*, char*); typedef int (__stdcall *impInitPAnsiChar)(CallBackPAnsiChar); CALLBACK MyCallBackPAnsiChar(char* Protocol, char* Address, char* Command, char* Flags) { printf("\nIR Data received: Protocol: %s, Address: 0x%s, Command: 0x%s, Flags: 0x%s", Protocol, Address, Command, Flags); fflush(stdout); } int main(int argc, char **argv) { impInitPAnsiChar InitPAnsiChar = NULL; // Load DLL file HINSTANCE hinstLib = LoadLibrary(TEXT("USB_IR_Remote_Receiver.dll")); if (hinstLib == NULL) { printf("\nERROR: unable to load DLL\n"); return 1; } // Get function pointer InitPAnsiChar InitPAnsiChar = (impInitPAnsiChar)GetProcAddress(hinstLib, "InitPAnsiChar"); if (InitPAnsiChar == NULL) { printf("\nERROR: unable to find DLL function\n"); FreeLibrary(hinstLib); return 1; } if (InitPAnsiChar(*MyCallBackPAnsiChar)) { printf("\nInit DLL with InitPAnsiChar successfull"); } else { // Unload DLL file FreeLibrary(hinstLib); return 0; } while(1) { } //return 0; }

Hi All,
MAIN QUESTION:
Is it possible to Call specific function within a GUI
So I have a script with multiple functions although I don't want to use every function every time.
My Idea is to create a simple GUI which allows me to select what functions I want to use then run the funtions by clicking a button.
I have already made a GUI which allows me to select specific .exe's I would like to run after selection it runs the .exe one by one.
This script is on my work laptops and cannot access it right now.
Who can help me with this?
GUIcreate
Func1
Func2
Func3
Then have a boxes which allows me to select the specif Func.(I used GUIChecked and Unchecked in my other script)
Then a button which executes/calls the selected functions
