value A string containing the data to send to the specified item.

DllCall
Calls a function in an application's dynamic-link library (DLL). There are three forms of this command. The first
does not return a value. The second is a function that returns an integer (LONG/DWORD) value. The third is a
function that returns a string value.
In the first two forms, the DLL function must be a PASCAL function that takes a single LPCSTR (long pointer to a
constant string) argument. In the third form, the DLL function must take three arguments, an LPCSTR, a pointer
to a BYTE buffer, and an integer.
C or C++ DLL functions called by the first form of DllCall must have prototypes equivalent to:
extern "C" __declspec(dllexport) void __stdcall fn(LPCTSTR szParam );
C or C++ DLL functions called by the second form of DllCall must have prototypes equivalent to:
extern "C" __declspec(dllexport) dword __stdcall fn(LPCTSTR szParam );
C or C++ DLL functions called by the third form of DllCall must have prototypes equivalent to:
extern "C" __declspec(dllexport) void __stdcall fn(LPCTSTR szParam , BYTE *pBuffer,
int cMax);
Syntax
DllCall "libName", "function", "argString"
integerVariable& = DllCall ("libName", "function", "argString")
stringVariable$ = DllCall$ ("libName", "function", "argString", "maxStringLength")
Argument Description
libName The name of the .DLL file to be called. The DllCall command works even if the
dynamic-link file does not have a .DLL extension. The value can be an
expression.
