• Smart Device Development How does SCardTransmit crush windowsXP?

  I am trying to get and send data to an EFTPOS device through USB. The driver in windowsXP is "smart card reader". After smart card connection estabilished, SCardEstablishContext(), SCardListReaders(), SCardConnect(), SCardGetAttrib() all passed, then SCardTransmit() be called. My problem is if I call SCardTransmit() once or a couple of times with same length of response, my program can get correct response. But If 2 or 3 times continual calls of SCardTransmit and device sends different length of response to PC, PC reboots. Below call sends "commandHead" to device but get different response according to the contents in "commandHead". status = SCardTransmit(cardHandler, SCARD_PCI_T1, commandHead, 3, ...Show All

• Visual C# GetMethods(BindingFlags.Public) not returning anything

• Visual Basic Unexpected behaviour with INSTR function

  G'day, please forgive me as its my first foray into VB.NET (Normally a VB6 bloke). I'm getting some strange behaiour from the INSTR function. I wish to read in a CSV file but split the data into columns which I'll then plot. The data is structured such that the first record contains the channel names, then comes the units and finaly the data stream. A record can contain 200+ strings delimited by a "," the record is terminated by a CRLF so I use INSTR and VBCRLF. The first vbCrLf is picked up correctly - the expected number of channels is loaded into sHeaders (see below). BUT the next one sUnits is NOT loaded correctly - it actually misses a vbCrLf and continues to loads till the next vbCrLf appears after that one. ...Show All

• Visual C++ USB class

  I have been using the serialPort class for the last few weeks and I have successfully managed to implement a few small applications using the different methods within the class: read, readByte, etc. The applications operate with an RS232 connection to a separate p.c. running Hyperterminal. I would now like to begin implementing applications using a USB connection. Is there a USB class, or can I use the serialPort class Any help or advice would be appreciated. AFAIK there's no such thing. You will have to look to specific third party packages for usb communication if you want an abstraction beyond the driver level. Alternatively, you could check the DDK -- I seem to recall there being a sample ...Show All

• SQL Server show/hide report columns

  Hello, I'm currently investigating whether SQL Reporting Services might be the right solution to some reporting requirements I have been given (web reports). There is a requirement that some of the columns are hidden to begin with and can be shown by clicking on the header of one of the other columns. E.g. There is a list of clients and a "Total Revenue" column, clicking on the "Total Revenue" column header would show an additional 5 or so columns which show a breakdown of different figures that make up the total revenue. So my question is this: Is it possible to show/hide columns by clicking on the headers of other columns in the report Thanks, Lachlan I needed to conditionally change the v ...Show All

• Visual Studio 2008 (Pre-release) How to return a List<T> using WCF

  I have an application that reads lots of small blocks of records from a data store primarily to supply the application's numerous lists (drop-down etc.) I have been returning DataSets using web services in .NET 2. Now I would like to implement the same functionallity in WCF. I have already got methods that return DataSets in WCF that duplicate the functionallity. However it occurs to me that I could make a list of the rows represented as class objects and return a list instead. The idea being that the server is doing some of the work for me and that I could more easily port a web version of the service if the result is in List<T> form from the service. At this point I take a DataSet and create the List<T> at the client which ...Show All
