The parameter for OpenPort is a BYREF string. Try using:

setting = UCODE$(setting)
commObject.OpenPort(setting)

Sorry about not wrapping the code segment...

Anywho, it appears that making the call as José has suggested has had little effect on the value that OBJRESULT returns. Not that I know what the heck I'm talking about, but does whatever I've presented thus far make me a candidate for using the 'generate dispatch interfaces only' flag in the COM browser? I only ask because things moved that way in the former topic.

**C.M. Rouleau** · 29 Oct 2008, 11:36 AM

More information...

José,

I just thought I'd throw this out there because the code below worked, and it was based on your TypeLib browser (and wrapper functions). Basically, this is what I'm trying to do in PB9, and it doesn't seem to be working out so far. I figure if I can get these few calls to work, I may be on my way to doing more with the library.

'declare some things
LOCAL hr AS LONG
STATIC ppCommInterface AS DWORD
LOCAL n AS LONG
LOCAL Response AS STRING

'create an instance of SMIHost
hr = TB_CreateObject("SMIEngine.SMIHost.1", ppCommInterface)

...and then to open the port, I used the following:

COMBOBOX GET TEXT CBHNDL, %IDC_BAUD TO setting$
hr = SMIEngineISMIComm_put_BaudRate(ppCommInterface, VAL(setting$))
hr = SMIEngineISMIComm_put_Parity(ppCommInterface, %smi_none)
COMBOBOX GET TEXT CBHNDL, %IDC_COMPORT TO setting$
hr = SMIEngineISMIComm_OpenPort(ppCommInterface, setting$)

**José Roca** · 29 Oct 2008, 11:54 AM

Can you post the wrapper function for SMIEngineISMIComm_OpenPort?

My previous suggestion was based in what you had posted, but maybe (I'm just guessing) METHOD OpenPort <1> (BYREF PortName AS STRING) should be METHOD OpenPort <1> (BYVAL PortName AS STRING). I don't have SMIEngine.dll, so I can't inspect the type library using my tools.

I also have a new browser for the new compilers:
http://www.jose.it-berater.org/index.html

It would be useful to know if my browser also resolves the parameter as BYREF STRING or BYVAL STRING.

**C.M. Rouleau** · 29 Oct 2008, 02:41 PM

José,

You are right- your [new] browser resolves the parameter as BYVAL, and - here's the best part - that small changed solved my problem. Man, you're good! So, why does the PB Browser get it wrong, and should I use the include generated by your new browser instead of PB9's?

-CMR

**José Roca** · 29 Oct 2008, 03:47 PM

Some type libraries are difficult to deal with, either because they are buggy or because some attributes are missing. I will tell Steve Rossell about this problem.

You can use the interface declarations generated by my browser or the ones generated by the PB COM Browser (changing manually the BYREF STRING parameter to BYVAL, of course), as you wish.
