Impossilbe to find entry point for WinSATGetScore in WinSATAPI.dll

[Silver Black 23]

Hi! I have this declaration:

 

function WinSATGetScore(out Score: TWinSATScore): Boolean; external 'WinSATAPI.dll';

But I get the run-time error "Impossible to find WinSATGetScore entry point procedure in dynamic link library <executable.exe>".

What's wrong in the declaration? The DLL is a system one and thus included in my Windows 11 System32 folder.

I dont know so much about DLL exportations, but many DLL (system) using export the procedure by "name" or "index"... then maybe you can try some like this:

Quote

function FuncNameXXX( same params type like in DLL procedure): type-resulted; external "DLL-name" name 'name-func-into-DLL'   // or  ...  index Idx-func-into-DLL   <--- need see documentation!

Is not a normal DLL is a COM object.

 

This is a type library definition (you can make your own with IDE).

But did you create this on the fly just now, for me?! How did you do that from the original DLL? Thank you so much mate!

the RAD has a TLibImp exe 32/64 that allow create your  TLB in command-line (IDE show dll 32bits).

param -P allow create your Delphi Pascal imports

 

RADStudio\11.0\bin64\tlibimp.exe” -P My64bit.DLL

I had looked into that, but I wasn't sure, now I saw the registered dll, thank you again.

 

However, I still don't know how to call the function I used to call like this: 

function WinSATGetScore(out Score: TWinSATScore): Boolean; external 'WinSATAPI.dll';

How the new WINSATLib_TLB.pas unit created from the IDE should help with my problem?

I don't know nothing about WinSat, but what you knew in the past is different from what it is now.

Look at new TLB that i post and this piece of source ... i hope this can help you.
