Modifying Code To Enable DataGridView
Nov 5, 2011
I'm testing the code below from another author, which works well for reading in the data. Despite this, once the data is populated I also need the DataGrid to be able to accept and delete data too. Is it possible to modify the code for this? I tried several things (in properties too) but am not sure if it is possible in this example.
Dim statesXml As XElement = _
<states>
<state name="California">
<abbreviation>CA</abbreviation>
<year>1850</year>

From my initial readings on unit testing it is wise to put all of your setups and tests in a separate project from the code being tested.I've recently begun reading The Art of Unit Testing, trying to discover how to break dependencies on things such as database calls.The methods offered involve changing areas of the test code, such as adding specific interfaces and "stub" methods to the production code.This seems to defeat some of the good things about keeping tests and production code separate.Is there any recommended dependency-breaking technique that doesn't involve changing production code?

I modified some code to suit one of my other programs, but have come across a difficulty: For some reason, the output file is not outputting. I can tell all the calculations are being made (my computer is loud), but it's just not outputting.What should I look out for when modifying stanav's code that would cause the output file not to be outputted ?

I've seen this great example of serial communication in VB.NET
[URL]
I try to use it in a project I am working on but somethings are not clear to me.
1: Now the send and received data is shown in one RichTextBox but I would like to split this into two RichTextBoxes (RtbSend and RtbReceived).It is unclear to me how and were data is assigned to the RichTextBox?
2. the received data is shown in the Richtextbox as one long line, I would like to get a new line for every send message.So for example: I I send "test" four times, I would like to see:
Test
Test
Test
Test
now I see: Test Test Test Test I've tried ctrlf but this does not work.The example describes that "comPort_DataReceived" is executed when data is waiting in the buffer. Where can I see the eventhandler responsible for this? How does it know data is waiting?The problem is this kind of coding is a bit to difficult for me. I want to understand the code before I implement it into my project.

I have a core EXE I wrote to serve a series of purposes. Another editor that goes along with it needs to repackage that EXE along with the script that EXE interprets. That is simple enough.
However, I need to give users of this stuff the ability to give that repackaged EXE an icon of their own choosing, but they do not have the source code to manually compile that EXE.
I know some magic with file streams and binary manipulation could do this, but I have the sinking feeling that that's pointlessly doing this the hard way and there may be a better way. Maybe the EXE itself can reset its own app icon per instructions given to it.

I've got to do some special things with a RichTextBox. I have to add syntax highlighting and I need
to be able to find out what character was added/removed/inserted at what position every time a key
is pressed. Is there some way to edit the existing, or is there a open source (.net compatible,
preferably VB.net) available for download? I've tried making my own, the problem is, it has to have
every function normally available and I don't have enough time to implement all of that.

I need to edit handler mappings of framework 2.0 to use .net 4.0 (basically run .net 2.0 code under .net 4.0 CLR).
The code below works fine under win 2003 server, but on Windows 2008 server webservicefactoryHandler2.0 is renamed as webservicefactoryHandler4.032_1245.
I don't know how to access/edit this name or infact retain the name and just change its value to Microsoft.NETFrameworkv4.0.30319aspnet_isapi.dll from Microsoft.NETFrameworkv2.0.50727aspnet_isapi.dll.
