Com port communication

Toddy_Boy

Hi Guys

I need to record a weighscale reading through a com port. Many of the posts doing a similar thing on the forum are quite old and use nfcomm. Is there a better way of reading the com port? I'm using Nav 5.1 on SQL Server.

I've registered the nfcomm ocx butit does not show in the list Automation list, so how do I decalre a variable of type nfcomm?

Cheers

Use mscomm32.ocx (Custom Control). It's the tried and true method.
It's an OCX not Automation Controller.

This website should help you with downloading mscomm32.ocx. Register if afterward.

Thanks for the replies, I have the MScomm32.ocx installed from VB6, and have read the thread on using the control however I am at a loss as how to declare a variable of type MSComm ](*,)

What am I overlooking?

Cheers

if you declare a variable do you see the DataType OCX ?
If no, you must expand your license to granule 1750.

Ahhh ... now it make sense, I've never used that before. Thanks a lot. \:D/

Now does anyone have a lorry weighscale I can borrow :P :P

I have declared the OCX

Name       DataType   Subtype                                                       Length
CommCtrl  OCX          Microsoft Communications Control, version 6.0	

and get the message Cannot load the selected type library #-o

Any ideas?

which nav version are you using? you get the error when you run it?

Toddy_Boy

Nav 5.1, I get the error when I try to save the form in the object designer.

ara3n

I don't get the error. did you try to register it from navision? Tools->custom controls?
Also I've put the ocx in windows\system32 folder.

did you restart nav? os?

Toddy_Boy

from Tools->Custom Controls I can see the OCX

InprocServer32 Name
C:\WINDOWS\system32\MSCOMM32.1 Microsoft Communications Control, version 6.0

When I try to register/unregister it I get the error

Could not load the OLE control

From the list of OCX controls I clicked Control->Browse, found the MSComm32.ocx in the system32 folder, clicked on it at which point something registered the OCX. Now I can add it to the form. YEY!! \:D/ \:D/

Thanks for the help ... tho I still need a weigh bridge for testing

ara3n

hmm. Haven't tried it myself but.
