I thank you all for your help.

ii) Check the calling convention of the library. Your code above is assumning the STDCALL convention, which is fine for Windows system dll's etc. If the library "toto.dll" is a typical 'c' library then you'll probably need to use the CDECL convention. For this use CallCFunction() in place of CallFunction() etc.

Thanks, but this is not the solution. The problem was that all the operation executed on the procedure works : i can see the data returned by the dll. But i have error on the end of the procedure.

Do i have to release the handle ????

I have found that i i dont use the delete and close function of the dll it works.

Very strange. I think that the datas are store in memory and so are not destructed.

Bizarre.

did you see DeDe's answer?
seems you misspelled the close-call...

In fact there is a bug on my use of the dll (because of poor dll doc)

i have to write this

CallFunction( 0, "dll_Close",Handle)

in place of

CallFunction( 0, "dll_Close")

thanks to you (and to a delphi forum were the dll was implemented)
