VS 2010 Writing To Parallel Port / Windows 7 64-bit

Mar 11, 2011

Does anyone have experience writing data to the parallel port (printer port) in Windows 7 64-bit. I have been trying inpout32.dll, inpoutx64.dll and following all the info on http://www.highrez.co.uk/ and www.logix4u.net but can't get anything to work. I have an on-board parallel port at &H378 - not an add-on card - and have tried various modes in the BIOS (standard, ECP etc). I have a background in electronics so I am confident my testing methods are sound; I just cannot get a data bit to change state under program control. I need to send data to an 8-bit port on some 20th Century electronics so serial/USB interfaces are not really an option. There must be a way to control those 8 data bits in Windows 7, mustn't there?

Writing A String To LPT1, The Parallel Port?

Dec 18, 2011

I have a fairly old radio receiver. (Icom R70) A friend and I have built an interface to control it from my computer. The interface is parallel. For me the interface is a black box. (My friend is the electronics specialist)In the description (25 years or more old) the statement to set a frequency and receive mode (like Am, FM etc) on the receiver is:print ".0:087330"

Today I am working in VB.Net and on Windows7 pro. I have already spent several days figuring out how to do this, but can't get it to work.I have found inpout.dll, but that does only allows me to write one byte at the time, and if I break up the above string and send nine individual characters, it does not work.

.net - Which Version Of Visual Studio 2010 Contains Visual Basic SharePoint Templates

Aug 5, 2011

Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.

At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates

Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

Parallel.For Termination - Service That Scans Network Folders Using A Parallel.for Method

Jan 16, 2012

I have a service that scans network folders using a parallel.for method. However recently I am finding if I stop the service then while windows says the service is stopped the process is still running in task manager. However it is at 0 cpu and the memory does not change. If I try and end the task (even a force in command prompt) it just says access denied and i have to reboot the server. What would be the best way to make sure everything terminates? I thought of adding a global Boolean that in the stop procedure it turns true and part of my parallel code will check for that and call s.stop.
