      Hello all!
      I got the Acroname Programmable USB Hub based on BrainStem platform. I will use it to manage ports and read current.
      They have development kit (BRAINSTEM DEVELOPMENT KIT) with examples for any languages like C#, C++, LabVIEW and python but no AutoIt.
      The kit include BrainStem2.dll (x32 and x64), BrainStem2_LabVIEW.dll, BrainStem2CLI.dll and many examples.
      Anyone used this dll and implemented it in AutoIt?
      Please share some example for Device Discovering, User LED Flashing or power enable/disable on port to start play with this HUB

      Hi guys!
      A pretty simple UDF to convert HTML to PDF using wkHTMLtoPDF.
      It uses the C API of the tool (DLL), so no external process, no ActiveX or COM sh*t.
      See the example, and the documentation of wkHTMLtoPDF.
      Cheers

      This is relevant
      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,
      i want to start a new application that capture a screen or image from webcam an read all barcode inside the picture.
