• Visual C++ COM port

  I am looking at moving a company utility that collects/analyses/formats/displays diagnostic data collected from specialized equipment via a COM port to a more up to date code platform: it is currently a 16 bit Windows app.  I am evaluating Visual C++ 2005.  I am searching around for classes/components/anything that will help me with this task.  Can anyone point me in the right direction   Am I asking in the right place There are no such limitations of COM1 to COM9. If using a commport > 10 you have to use CreateFile( "\\\\.\\COM10",...) I disagree with you comment about an additional abstraction layer. Even ...Show All

• Visual Studio Express Editions Project Files

  MSVC++ 6.0 had a wonderful feature in which during the compile process of the main code (which had, of course, user #include file(s) in it), the environment would identify ("discover") *all* header files upon which the project was based - automatically. Do the later MSVC versions have this capacity If so, how do I set up my environment to make this happen and where in the IDE would these files be displayed Thanks. This could be done using multiple ways in VC2005. Some using the IDE and other using a compiler switch (/I). Take a look at http://msdn2.microsoft.com/en-us/library/73f9s62w.aspx where ...Show All

• Visual C++ Examples for Visual C++ Express

  I am having much more trouble that I would have expected in getting started with the beta.  I did some C++ programming about 10 years ago.  I now want to bring this work over to C++ Express.  I want to use the MDI approach, but have not been able to find an example that works.  I want to download something, unzip it, select it from the new project menu.  I don't want to have to figure out VB, C#, or earlier versions of C++ to make the thing work.  Is there  something out there Gordon. The Express-Edition mainly targets the .NET Framework. There is no MFC library which suppo ...Show All

• Visual Basic Control codes - how to type them into a programme

  Here I am struggling to get my PC to talk to an electronic sign board (junk from an old callcentre that will now do service as a score board at the school I teach at). Background: I am able to have the sign working using it's own software, so it does function. Unfortunately this is a SCO UNIX box that runs a mass of other things, with the sign being a miniscule part of the functions. This footpring is too big! Problem: I have the protocol for initialising it, and was able to capture some of the control codes via hyperterminal. The code I captured is <Esc>, also known as hex 1B or 0x1b. the captured character looks like a le ...Show All

• Visual Studio Setting compound property from task

  I'm currently porting our build to use MSBuild (From NAnt). Part of the plan is to produce a 'build constants' project to be included in all other build projects, with defines globally used properties. One of these is a formatted time string, used when we archive our 'old' code (to save a developer accidentially wiping out uncommitted changes if doing a full build by mistake). How can I perform the equivalent of calling a task that defines a number of output properties from a property group, and set a new property to be a concatenation of these returned properties Cheers, James. Yes, if you use CreatePrope ...Show All
