LoadLibrary()

Loads a DLL and returns a handle that can be used in function calls.

Added in Version 6.0/2012.

dllhandle = LoadLibrary(string dll_name [, array options])

Argument	Contents
dll_name	The name of the Dynamic Link Library (DLL)

Option	Type	Contents
StdCall	Boolean	If "true" assumes the _stdcall calling convention, where arguments are passed on the stack and the called function is responsible for removing them off the stack; default is "false"
FastCall	Boolean	If "true" assumes the _fastcall calling convention, where some arguments are passed in registers and the called function is responsible for popping other arguments off the stack; default is "false"
Cdecl	Boolean	Assumes the _cdecl calling convention, where the arguments are passed on the stack and the and the calling function is responsible for removing them off the stack; defaultis "true"
Return Type	String	Can be "double", "int" or "string"

A DLL handle.

The options array is an optional argument.
The dll remains loaded until the variable is discarded.
In 64-bit programs the calling convention option is ignored, since all 64-bit programs use the equivalent of the FastCall calling convention.
In a 32-bit environment, all Standard Windows API functions use StdCall.

// You can use this to hook into Windows API. Take for an example:

// int MessageBox(HWND hWnd, LPCTSTR lpText, LPCTSTR lpCaption, UINT uType)

// declared in user32.dll. You would actually call the MessageBoxA version with

hDll = LoadLibrary("user32.dll")

args = {{"long",0},{"char *","Hello World"},{"char *","My Title"},{"long",0}}

opts.StdCall = "True"

opts.[Return Type] = "long"

ret = hDll.MessageBoxA(args, opts)

Error Type	Meaning
Error	An invalid parameter was specified
NotFound	The DLL or one of its required components was not found or could not be loaded

Function	Summary
CallDllFunction()	Calls a function in a Dynamic Link Library (DLL)
LaunchProgram()	Starts a Windows program
LaunchDocument()	Open a document, executable, or URL with the appropriate program
