Template:mIRC Guide The /dll and $dll() features allow you to make calls to DLLs designed to work with mIRC. The main reason you would want to do this is that processing information in a DLL can be far faster than doing so in a script, so for intensive data processing a DLL would be more efficient.

Note: mIRC also supports calling COM objects, for calling non-standard DLLs.

Synopsis

If you are using a dll:

/dll <filename> <procname> [data]

/dll -u <filename>

$dll(<filename>, <procname>, [data])

$dllcall(<filename>, <alias>, <procname>, data)

Parameters

• <filename> - The filename for the dll you wish to use.
• <procname> - The name of the function/procedure you wish to call.
• [data] - The optional parameters for the function/procedure.
• <alias> - If you use $dllcall, it calls the function asynchronously, meaning that the code won't halt, $dllcall won't return a value. Instead, mIRC calls the specified <alias> when the function finished.

If you are making a dll, the exported function must have the following function prototype:

#include <windows.h>
int funcName(HWND mWnd, HWND aWnd, char *data, char *parms, BOOL show, BOOL nopause);

• mWnd - The handle of the main mIRC window.
• aWnd - The handle of the window in which the command is being issued, this might not be the currently active window if the command is being called by a remote script.
• mWnd - The handle the main mIRC window
• mWnd - The handle the main mIRC window
• mWnd - The handle the main mIRC window

Note: These functions must use the stdcall calling convention. (This is also the standard calling convention for all other Microsoft Win32 API functions.)
