Reading Output From A Serial Device In Visual Studio 2010?
Aug 31, 2011
Using visual studio 2010 on a PC running Windows XP SP3 (32bit) I am trying to read the output from a serial device but only get timed out error?If I open hyper terminal I can see the output, so the hardware and connections are good and the command to send data is working as well?When debugging I have no errors, when the program is run (in debugging mode) I get a timed out error from after the do loop (test=2) All I want to do is have my device output printed to TextBoxLockOut.Text? Note "comstring" grabs my com port the serial device is using - on this computer it is com4, it is a public string
Dim inputline As
String = ""
Dim command As
String = ""

I want to read a VB or C# Visual Studio project file so I can find out which files the project uses (code source files, not images or whatever).I simply opened a vbproj and csproj file in notepad and found that they are in XML format. A simple example follows. The red parts is what I need:
<?xml version="1.0" encoding="utf-8"?>
<Project ToolsVersion="4.0" DefaultTargets="Build" xmlns="http://schemas.microsoft.com/developer/msbuild/2003">
<PropertyGroup>
<blabla... />
[code]....
However, it seems it cannot even find the Project element, because the query errors saying "Sequence contains no elements" on the 'Single' call...

I need to read a Visual Studio Solution file (.SLN files) to figure out which projects belong to this solution.By opening a SLN file in notepad, one can see that the projects are stored like this:
Microsoft Visual Studio Solution File, Format Version 11.00
# Visual Studio 2010
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "RadioGadget", "RadioGadgetRadioGadget.csproj", "{AE664C6C-000B-44D9-BAD8-0200D6ABE90D}"
[code].....
excluding the ... part obviously (which is just some guid I don't care about). Then I need it to match the rest too, and more importantly, I only need it to return the filename that I've underlined in the example. When I simply use 'm.Value' as I am now I think I will get the entire matched string back, right? That gets me nowhere as I'd still need to parse the filename out of that manually... Bit pointless to use regex then...

I'm writing a small pet program in VB2010 Express
I have 7 labels
Form1
Label1 to Label7
I want these labels to display the text from a third party Software program.
The text is displayed in a child form of the main form the text is in
"window handle is 000E0678"" RichEdit20W"
The text scroll up continuously,
every time - let's say
John (10year) 'is displayed, it takes the 10y and place it
in Label1
Ann (22year 7Street) 'is displayed, it takes the 22y & place it in Label2 7St in Label3
get that text in the labels I only know a little VB. I have used Spy++ to get the window handle
Yes lots for the pro's but we dont understand it, if its just code we dont know where to start or make changes to that code. This is something simple that beginners will understand

In newer editions of .Net I can pass -1 for the output size for VarChar(Max) columns, but in Visual Studio 2003 I get the following System.ArgumentException: Invalid parameter Size value '-1'.

I've created a SSIS script task for debugging: printing SSIS variables and their values. This is done with (a maybe restrictied version of) Visual Basic. Rather then creating a message box or writing to a file I'd like to write to the debug output of Visual Studio - or to some other window available in Visual Studio when running a SSIS task. Something like fprintf( stderror, "Hello world!" ) in C. I suppose I need to get the Stream Writer Object connected with the debug output. But how do I do this? I also tried Console.WriteLine() but this didn't succeed.

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?

I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere. I downloaded the Direct X SDK for August 2009, but I can not add the .dll files to the reference list. Is there anything I can do to add them? I need the references for programming reasons.

Private Sub receive_data(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort1.DataReceived
Dim aBuffer(255) As Byte
Do While SerialPort1.BytesToRead > 0
[code]....
Basically, what I am trying to do is everytime I receive data from the serial port, I turn that data into an array (aBuffer) and I then call another sub using that info.The problem I'm having is that everytime I receive data, the array only fills up to the first 8 bytes! This isn't a problem when I receive smaller packets of 6 bytes but anything else gets chopped off.
What is really frustrating is that it seems quite fickle. I've read somewhere that this happens because the computer is handling the bytes received faster than they are being put in the buffer?? Not really sure but if I put a couple of breakpoints during debug, sometimes the array fills up correctly... Note the maximum size of any one incoming message would be 255 bytes.

This is an amateur radio project. I have a TNC (modem) that receives a digital stream (AX.25) from my radio. The TNC decodes the AX.25 frames and translates them to KISS frames (the protocol used between the TNC and the PC, see documentation here: [URL] It sends the data as HEX values.
What I'm looking for on the serial stream is the beginning of a data frame marked by 0xC0 0x00 and ending with 0xC0. Should be easy. Using serialport.readbyte() I should get binary data that I can convert to hex and look for the beginning of a data frame and then convert the subsequent data to ascii, as it will be text from a chat session.
Just to try it out and see the raw data coming from the port, I use teraterm or realterm and capture the data and it's a mix of junk (control frames and what not) and valid text. When I display the same data in a text box in VB I get data that look like this:

I got an Arduino hooked up to the PC and would like to read the serial port of it. I read the serial port in Visual Basic with com.Readline, but it won't read everything. It looses around 2-3 lines that were sent over the serial port to the Visual Basic code. They get "lost".

To send serial data from Arduino Mega 2560 to a VB.Net PGM, then the VB.NET pgm will read data then send to via FSUIPC (an Addin DLL) to ms flight simm 2004.OK that said here is the question: how can I write or phrase or construct the proper syntex needed to 1-limit the data sent,or in reading the data-limit the data read?I have enclosed the VB.NET code and the Arduino code. Please take a look. I am very new to both,but I try hard. all the code works but I get strange all most random data in VB. The FSUIPC end works OK, I can send to and receive from Ok.It's the VB pgm that gets the data wrong some of the time. say 8 out of 10 it is OK then button x will also turn on or off another check box then do what was aked. It seems that I am not clearing the receive buffer so I get a last chr sent before.I have tryed readline, readexisting,readbyte but I don't know how to phrase or construct any but the readline. I have tryed to flush the buffer in both codes but, well I am stuck. [code]

At present I have wrote an application (in-house CRM, vb .net 2010) which allows me to send emails under the selected customer & I categorised these emails.As these are categorised I can return data to display email history in my program by using search criteria:
Dim oMail As Outlook.MAPIFolder = oNS.GetDefaultFolder(Outlook.OlDefaultFolders.olFolderSentMail)
Dim sSearch As String
sSearch = "[Categories] = '" + "[" + tAccount.Text.Trim + "]" + "(" + tShipTo.Text.Trim + ")'"
Dim oItems As Outlook.Items = oMail.Items.Restrict(sSearch)
However the limitation to the above is it only looks at sent items & no other folder.My ideal solution would be to display all email correspondence for a certain contact.
