View 1 RepliesParsing Intel Hex File Through Serial Port?
Jan 20, 2010I am new to VB .NET, now studing VB2008.Being an 8051 microcontroller enthusiast my dream is to program an at89c51 with my own device. This requires one GUI that can communicate with the device programmer via serial port. I have found the post "Serial Port Communication in VB.Net" by PsychoCoder at I have already built an interface in VB6 that can open and save .hex type text files which is in Intel Hex Format.

View 1 RepliesRead A 12 Byte Hex String (RFID Tag ID) Using SerialPort Control?
Apr 23, 2012I'm trying to make an application that can read a 12 byte hex string from the serial port and display it into a text box, the source is a RFID module that is connected to my USB port using a RS232-USB converter.My first problem was accessing the text box in the datarecieved event due to invalid cross-threaded operation. Upon googling that, I copy/pasted the code I needed to get it work, these are all the cross threading functions.The OpenPort function and Datarecieved event are my own code, the rest I got off google. The application then worked, but I would get an incomplete code, the first swipe I would get all 12 digits, and at every other swipe, the first byte would vanish. Upon some more reading, I decided to make an array, the size of the incoming data (shown in the code below), but now I get the cross-threading error again.I know there's something wrong with the way I'm using the array. This is way beyond my VB knowledge, and I'm in o I'm an electronics engineer and self taught myself a little programming to create some apps for my hardware.Updated code:

Symbol Barcode Trigger & Rfid Trigger
Oct 6, 2011i have to develop a software for motorola mc9090 that reads barcodes and rfids simultaneously, so i need to catch two different triggers: the one on the keyboard for barcodes and the other in the backside for rfids.the problem is that i didn't find any sample that illustrates how to set the trigger to read only barcodes, i found something on emdk 2.5 samples that shows how to set the trigger to read rfids but nothing for barcodes. So when i press any trigger the barcode reader is always enabled with rfids reader.Does exist a way to manage them with separated triggers?
View 1 RepliesConverting VBA XML Reader To .net?
Feb 10, 2011I am currently rewriting a VBA XML reader to a VB.net version for a project. I have the following code in VBA:
Dim XML_Doc As Object: Set XML_Doc = CreateObject("MSXML2.DOMDocument")
Dim XML_Detail As New ADODB.Recordset: XML_Detail.ActiveConnection =
"Provider=MSDAOSP; Data Source=MSXML2.DSOControl.2.6;"
I was told that I should be able to use almost the exact code in my VB.Net version but I am running into some problems. I added as a reference to the VB.net project the Microsoft ActiveX 2.8 so I can use the ADODB.
The code in VB.Net is
Dim XmlDoc As Object : XmlDoc = CreateObject("MSXML2.DOMDocument")
Dim XmlDetail As New ADODB.Recordset : XmlDetail.ActiveConnection =
"Provider=MSDAOSP; Data Source=MSXML2.DSOControl.2.6;"
When running the application it gets to the XmlDetail and throws the following error:System.Runtime.InteropServices.COMException was unhandled. Arguments are of the wrong type, are out of acceptable range, or are in conflict with one another.

View 9 RepliesFilestream Reader From FTP?
Aug 25, 2011I am attempting to read specific lines of GIANT text files (> 150 MB) with hundreds of thousands of lines. The files are contained on an FTP site. I can successfully open the files using FTPwebrequest and streamreader but to get to a specific line using streamreader, you have to read every line before it. Obviously this takes a lot of time when you need to get to the millionth line.
A much faster way, I think, would be to use filestream and the filestream.position function. However, I'm not sure how to open a file as a filestream from FTP. I have tried:
Dim ftpaddress as string = "ftp://####@ftp.textfile.asc+"
Dim fileStream1 As New FileStream(ftpaddress, IO.FileMode.Open, IO.FileAccess.Read)
