Trouble linking to DLL

[Ken Trumper]

Hi all,

I'm writing an application on PB5 where I'd like to use Maxim IC's 1wire bus and their USB converter, but i can't seem to link to the library. The error I get is "The procedure entry point TMREADDEFAULTPORT could not be located in the dynamic link librabray IBFS32.DLL"

My syntax looks like this:

DECLARE FUNCTION TMReadDefaultPort SDECL LIB "IBFS32.DLL" (PortNum AS INTEGER, PortType AS INTEGER) AS INTEGER

LOCAL RetValue%, PortNum%, PortType%
RetValue% = TMReadDefaultPort(PortNum%, PortType%)

I've tried the three different call types and none worked. Just to verify I used a 3rd party program to verify the function call in IBFS32.DLL and its correct.

See the ALIAS keyword.

Seems to have worked that Edwin. I used ALIAS as the exact same name.

THANKS!

If it comes up again, here is a useful utilty for you...

(enhanced UI/ PB/Win 7x conversion by MCM
Show exports and imports for PB/Win 6x, 7x (original by Torsten Reinow)

That will give you the ALIAS name required (case IS signficant) for all the functions exported from any PE executable (EXE or DLL).

I keep a link to this program on my Start/Software Development/Utilities menu.

Oops, this is the PBCC forum, meaning you may not be able to compile that yourself. I'll ZIP up an EXE and attach it today or tomorrow.

My bad, Mr. Montenigro already did that...

The thing is, the compiled result auto-UCASEs the names of any DECLARE [..] LIB or (in PB/WIN) any EXPORT function. Use ALIAS to force it to use a specific case, or a different name entirely.

You mean disguise the real names of your exported functions?
