Where can I get documentation ?

There are two ways to use a DLL:

1. Static linking
2. Dynamic linking

In order to use static linking you have to create an import library from the DLL. You can use libdef.exe or libimp.exe:
impdef.exe mydll.def mydll.dll
or
implib.exe mydll.lib mydll.dll

implib.exe will create the lib. impdef.exe will create a def file (ascii file) and then you can create the lib from it.

Then you create a C function that calls the DLL C function and link the import library.

HB_FUNC( THE_FUNCTION_TO_CALL )
{
TheCalledCfunction();
}

From your app:

The_Function_to_Call()

1. Dynamic link:

There is no need to create an import library. The DLL is loaded at rutime and unloaded once it is used. FWH provides the following command to use the functions from the DLL:

DLL FUNCTION FuncionName( param AS TYPE ) AS RESULT_TYPE FROM FunctionName LIB DLLName

in example:

DLL FUNCTION Shell_NotifyIcon( nMsg AS LONG, pNID AS LPSTR ) AS BOOL PASCAL ;
FROM "Shell_NotifyIconA" LIB "shell32.dll"

DLL FUNCTION Shell_NotifyIcon( nMsg AS LONG, pNID AS LPSTR ) AS BOOL PASCAL ;
FROM "Shell_NotifyIconA" LIB "shell32.dll"

Thats a FWH command, are you using #include "FiveWin.ch" ?

Windows API function Shell_NotifyIcon() expects different parameters:

You can not call it providing it a string

Why don't you use Msgwait() ?

You can change its source code to place it where you want

Do you want it just for Windows 10 ?

So better implement your own version that will work on all Windows versions
