Modifying Code To Enable DataGridView

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.

How To Break Dependencies Without Modifying Production Code

Jun 17, 2009

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?

Communications :: Modifying Existing Code For Serial Communication?

Sep 21, 2009

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.

Add Controls AND Code At Runtime

Jan 15, 2012

"add controls at runtime" how to add code to the controls. kinda useless with no code, ehh? all results only told me how to add the control, that's it. well, this result is different. i will teach you firstly how to add controls at runtime, then how to apply code to them at runtime

Firstly, add the controls:

[CODE]..............

Now run it. do you have a button on the form? if yes, excellent. if not, you made a mistake. try again now how to add code? you may have noticed that when you double click on any control, it says private sub button1_click(blah, blah, blah) Handles button1.click where it says handles button1.click is what determines when the code executes under what event for what control (in this case the click event for the button1). this won't work when adding code at runtime. did you notice in the above example i added a with event, and addHandler? this is what creates the handler (same as Handles button1.click)

Now we add the code for the runtime control

[CODE].........

Above, the addressOf button1_click tells the program to execute the sub button1_click when the button is clicked on (as determined by .click) but i know what you're thinking! your thinking "why would we even BOTHER doing this at runtime? isn't it easier to do it at design-time in the first place?" yes it is, providing your not writing a plugin. plugins are code based, not GUI (also reffered to as WYSIWYG). to update existing forms using plugins, you need to use this method.

Adding Code To A Form While In Runtime?

Sep 13, 2011

i am in runtime mode and have a form open. I do some calculations on it and based on those i generate some lines of VB code (concatenated and saved in a local variable). Is there a VB command that i can use that will take this code and INSERT it into another form?

i could copy the code, exit runtime, go to design mode and paste it into the form myself but because i want to do this for several subs for a lot of forms then it will become very time consuming.

Implement Code Snippets At Runtime In Vb?

Nov 27, 2009

I need to port an old Clipper app to vb.net. It relies heavily on user-written macros and indeed would be almost impossible to create without them. As VB is interpreted, I am sure it must be possible to implement code that the user has entered, but I have no idea how to do so!

VS 2005 : Edit Code At Runtime?

Apr 14, 2009

A change I made to the project's configuration must have disabled the ability for me to edit the code at runtime. I used to be able to pause execution and edit code on the fly, but I recently made a change to the configuration manager to build releases for x86 and all of the sudden I can no longer update code while running the app. This is very frustrating as I have to keep stopping and starting my app.

Runtime Variable Field Selection In Code Behind?

Jan 23, 2012

I have a list with several fields that is created from dataset from a linqtosql query. At run-time, the user gets to specify what field he/she wants to display from the list. In other languages, I can dynamically do this like:

valueIwant=mylist(i).[fieldnameImInterestedIn]

Where 'fieldnameImInterstedIn is itself a variable. How do I do this in VB.Net?

non-working actual code follows:

Dim patientdata = (From patientvar In pdfdatacontext.tbPatients Where patientvar.PatientID = patientid)
Dim patientlist = patientdata.ToList()
fieldvalue=patientlist(0).(reportrow.userselectedfieldname)

Format Gridview As Date/Time At Runtime In VB Code?

Feb 18, 2009

I am putting together a kind of "build your own report" page that will have up to 20 options for people to select.Each option, selected by checkbox or dropdown (probably) will add on to the SQL data source to pull only the information needed and display it in a gridview.For instance, the initial query is:

Select
C.Name,
From Clients as C

[code].....

How can I do this, preferably referring to the column using the column name of "My Position" and not a numeric...If this can NOT be done....The other option is to query everything and format it - and then hide columns in the gridview based on items that are not checked. Would this be easier? (Doesn't sound as efficient to me).

Code Compiles, Throws Exception When Loading Project At Runtime?

Mar 28, 2011

I've got a code sample below that will compile, but not run. Start it in the debugger by clicking the "step into" button on the toolbar, and an exception pops up before it reaches the first line of user code:

"Could not load type 'TestPrivileges.Win32Module+TOKEN_PRIVILEGES' from assembly 'TestPrivileges, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'."

Comment out either the 'Dim ... TOKEN_PRIVILEGES' line in the module or the 'Public Shared ... TOKEN_PRIVILEGES' at the end of the class, and the problem will stop occurring.Visual Studio 2008 as well as 2010 does it.

Module Module1
Sub Main()
Dim newState As Win32Module.TOKEN_PRIVILEGES = New Win32Module.TOKEN_PRIVILEGES
MsgBox("Here I am")
