MSCOMM32.OCX

[MSP430F149]

Hello,

I am new to Visual Basic, but I must write an application that reads the Serial Ports for testing devices. I am trying to use Mscomm32.ocx but it is giving me a hard time. I am running a Learning Version of VB 6.0, and everytime I try to load the component (MS COMM 5.0) in the ToolsBar I get the message that the license information for the component is not valid or is missing. I use regsvr32.exe to register the .ocx but nothing. I have tried everything I have found on the web. Does somebody know if in order to use this control (MS COMM 5.0) I need the pro / enterprise versions (I have the learning)? When I start to look for the MS COMM 5.0 to load in the ToolsBar I see that (SP2) is also included with the name of the control. Does it mean that this control was provided only with Service Pack 2.0? (I do not find this SP in Microsoft). I love Microsoft !

Thanks for supporting this dummy

The current service pack for VB6 is SP5. You can download that from :

http://msdn.microsoft.com/vstudio/downloads/updates/sp/vs6/sp5/default.asp

The current version of Comm Control is Comm Control 6. You can download that from:

http://activex.microsoft.com/controls/vb6/MSCOMM32.CAB

This may help you Let me know if this helps

I did exactly the same thing a year ago,
Basically, the LEARNING EDITION of VISUAL BASIC does
not have the tool to access the serial ports. You need to
get the PROFESSIONAL Version.

I am running a Learning Version of VB 6.0

Under Components I see:
Microsoft Comm Control 5.0
and
Microsoft Windows Common Controls 5.0 (SP2)

I am able to load both of them onto my toolbox.

 

[johnwm]

Did you download current SP and controls as suggested?
If so, What's the current state? Let me know if this helps

Hello all,

I tried downloading and installing MS COMM 6.0 as Johnwm suggested but I had the same results. I am able to load the control in the Toolbar, that is clear, but if I want to insert it in the form, then I get this message about the lack of license or that I must re-install the application. I have not downloaded yet the SP5 because it's quite huge, but I wll have to do it. I have re-installed VB several times, I have copied the mscomm32.inf into the "system" and "windows" folders, I have registered the ocx using regsvr32.exe but it won't let me use, it keeps asking for the license. Perhaps I really need a pro or enterprise version that I am trying to get it too. I run this VB 6.0 Learning Edition on Windows 98 SE (both in German) because the project is being held in Germany. I never heard of "English" versions of mscomm32.ocx but maybe that is the problem. Thanks to all of you for your support.

I am able to load MSCOMM into a form. No Error Messages. I cant test it because I dont know the control.

My system is a Clean install using Full OEM/T
windows 98.4.10.1988
AMD650

Windows 98 yr 2000 Update 2

I do show MSCOMM32.OCX Loaded
This info came from System Information

My Visual Basic 6.0 Learning Edition came with Visual Studio 6.0 SP3. I dont think I downloaded another SP because all I find at Microsoft is for .NET

you should check the 32-bit Modules Loaded section of System Information and see if you show the OCX there.

Hello jepadams,

Well you gave me hopes. I will check what is in the 32-b Module, but 99% sure the ocx is not there. I will check the OS updates too.

Once thing I will do is to clean the darn hard disk. I will format it and then install Windows 98 again, I will download all the updates from the Web, and then install VB 6.0 without the Service Pack (the one in the box is SP4). Then I will try once more. Then I still can install SP4, MS COMM 6.0 and even SP5 and try after every installation. I think that the PC has been used by many guys before and it is crowed with lots of trash.

Regards.

For the records.

Seems that THOMASNG was right or something was wrong with my Learning Version. I got the VB 6.0 Enterprise version and everything was solved.

Thanks to all for your great help.
