• Visual Basic Check Whether The Barcode Reader Read A Barcode

  May i know how to check the barcode reader has read a barcode and display the numerical value of the barcode and retrieve information accordingly from time to time. Must i use timer or is there any better way of doing it Thank you. As barcode readers are not standardize I would guess you should contact you specific barcode vendor to see if they have any components/libraries to interact with there hardware. I wouldnt have thought you would have to use a timer to read a bar code, but your not really that clear on the actual specifics of what your trying to achieve (I'm not sure what the time to time comment is all about). Either way contact hardware vendor first, you'll often find that they are pretty ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. What is Game Studio Express

  What is to be included with game studio express The Torque Engine Libraries An IDE Documentation I want to be able to make games on this system, but I don't want to have(although the ability to if need would be good) to use outside resources such as external libraries or engines. As a fresh, amatuer, student programmer, I am praying that XNA Express will be friendly to people WITHOUT industry knowledge. And lastly, do I need to own Visual Studio It will not include The Torque Engine, it will come with libraries simular to MDX (managed DirectX). XNA Studios is an IDE and there will be documentation but the docs may not be that great at the launch of beta. Managed DirectX makes DirectX easy to learn and use, you can have ...Show All

• Windows Forms Monitoring Changes on a Tab Page

  In my WinForms app I have a tab page with a bunch of controls on it (e.g. textboxes, checkboxes, buttons, radio buttons, etc.). Is there an event, or a few events, of the tab page that I can monitor to see if any changes to any controls on the tab page have been made Robert W. http://pocketpollster.com There's things you can do, like iterating through the tabpage's Controls collection and calling AddHandler for their events. However, different controls have different events and different event handler signatures. You'll need some commonality between the controls (like "Click" is usually available). What specifically are you looking for when you say "anything happened" Also look into ...Show All

• Visual C++ AT command response

  hi! I'm a newbie in vc++. I'm doing a project that connects my PC and mobilephone via bluetooth. I have already connected my PC to my phone and have sent AT commands using serialport1->writeline("AT") but i cannot get the response. Any idea how sample codes or websites that can answer my problem will be of great help. Thanks! There are a couple of sample programs provided with VC that could help. The Platform SDK sample uses the Platform SDK functions and such. There is another sample, I think it uses MFC, that uses a VB control to do serial IO. There is also a Technical Article in the MSDN about serial IO. There are many samples in other web sites of doing serial IO. Serial IO r ...Show All

• Visual FoxPro a newbie's question: how to mark columns in 2 databases with same values

  Guys, I'm a newbie of foxpro and I'm bad in English. I'm using Visual Foxpro6.0. Now I have two databases A and B with three same fields: id, lac, cell.

• Visual Studio Team System Copying the custom log file to drop location not successful

• Architecture multi tier to one tier with WCF and Linq?

  This weekend I have played a little with Linq, and in my current project we are using WCF (I love it). My current project is n-tier: per-table dal, dal, bll, sil, client. Well, looking to WCF and to Linq we will have something like this: per-table dal, dal --> Linq Bll will implement service interface. Sil --> user security will be into a dll that you can use through WCF (claims security). What do you think weekend paranoia :P Looks great ..but you will have to see how much LINQ is performant than traditional methods. http://DotNetWithMe.blogspot.com vikas goyal ...Show All
