    Here is a function I have used in the past:

    defun( DE_pluginsLoad (pluginName, pluginSymsList)
    prog((dllLib, symName); pluginName
    dllLib = axlDllOpen(pluginName); load dll library
    if(dllLib then
    foreach(symList, pluginSymsList
    symName = cadr(symList)
    set(car(symList), axlDllSym(dllLib, symName))
    unless(eval(car(symList)), axlMsgPut(list(lsprintf("'%s' symbol not present in %s Dll", symName, pluginName), 2)), axlDllClose(dllLib), return())
    )
    else printf("Can't find %s Dll\n" pluginName), return()
    )
    return(dllLib)
    ))

    Hi Dave, the function called  axlDllOpen  ,it's return value already correct,

    but how can i pass the parameters to dll's function?

    the C++ code for test is below:

    int numberAdd(&a,&b) 

    {return a+b;

    }

    The skill code is below:

    defun( testdll()

    dll_name="mydll"

    dll_lib=axlDllOpen(dll_name)

    if(dll_lib then

    printf("Opening %s.dll\n" dll_Name)

    dll_Add = axlDllSym(dll_lib "Add")

    printf("\nExample of axlDllCall with 1 of each argument\n")

    ret = axlDllCall(dll_Add 3 4)

    printf("Return  %L\n" ret)

    else

    printf("Can't find %s.dll\n" dll_Name)

    )

    )

    is this Codes right? could you give me any advice?Thk

    If you are unable to do so then you need to install some plugin so that there won't be DLL error, so far dell printer error 016-302 helped me to get the solution of this.
