VS 2008 Move Default Values From One Datagrid To Another?
Jul 28, 2009
I have in my database a table for Products with one field as Price. For each invoice i want to be able to change this default price, so in my table for Invoice Details I have made another field called Price1. When I am entering invoice details and i enter a product number i want my program to select the relevent default 'Price' and insert it into 'Price1' so that it will be editable and so it can be saved to my database.

What is the difference between these two methods for defining property value defaults? [code] Is there a reason to use one method over the other for defining the default property values in a class?

I have an unbound data grid and this code is not working to move one row to a new position. What am I doing wrong?
Dim Selected_Item = AccountList.CurrentRow.Index
Dim Item As New User_Information
Dim AccountItem As New DataGridViewRow
[code]....
It fails at the last line. Something about the new row information doesn't fit properly in the columns. One is an image, another boolean, and another string. I figured by copying the row to a new variable it would be exactly the same when I re-insert it.

I am trying to display an excel spreadsheet on a page using datagrid, but for some reason it is filtering out some of the cells, leaving a blank space instead. Also, the "$" sign won't show up in most of the columns.Could someone please take a look at my site and file, and give a suggestion as to why this would be happening? I've tried a bunch of troubleshooting on it, with no success.

I want to change the default behaviour of headers in a datagrid. By default, if the sum of all column's width is lower than datagrid's width, then background color appears on the header and I want to keep it just like header's color, as ListView does. I've attached an image to show you in a better way what I want.

i would like to know whether is there any ways of setting a masked value of "0.00" to a textbox? So when user input a value, let's say "200". The textbox will interpret it as "2.00". Similarly, if user enters "1000" it will display as "10.00".

I've been getting "Connection forcibly closed" errors and in researching a resolution, I have seen suggestions to money with the following web.config options, which currently are not set in my web app. Before I change them, I'd like to know what they are currently set to. Can someone tell me how to read these values from .NET code, preferably VB.NET, though C# is fine.

A Windows service written in VB.NET is using the My.Settings namespace for simplicity. There are only three settings to read, and these are read within the constructor of the ServiceLauncher.
I am attempting to install the service as such:
installutil GID.ServiceLauncher.exe
And this is successful, however the config settings it is using are not the ones within the GID.ServiceLauncher.exe.config file, instead it is using the ones baked into the app as Default Settings within Settings.Designer.vb (marked with DefaultSettingValueAttribute). [The questionable wisdom of Microsoft not allowing a developer to ignore default settings is another question entirely].
How can I further diagnose this issue, and maybe force a reload of settings? I tried calling My.Settings.Default.Reload, however this did nothing. All settings are application settings, and only differ by "value" from those in the auto generated file.
I have successfully attached the debugger using System.Diagnostics.Debugger.Launch() and true enough, the settings are still the default settings.
In anticipation of the question, the background: The reason for requiring configuration settings is because this is a very straightforward service that simply executes an exe; and this exe is in configurable location. There are other reasons also, such as I wish to have the service name configurable without recompiling.

I create a class "Planet" that can be inherited. One of the purposes of inheriting is to create a template with different default property values. Eg:
Public Sub New
MyBase.New
MyBase.ForeColor = Red
[code]....
Now, to stop the defaults serializing in the InitializeComponent method, there are 2 ways:If I've implemented the properties using the 'DefaultValue' attribute, and made them overridable, the attribute can be overriden with the new value.The problem with this is, there's no way to just make just the attributes overridable, as opposed to the whole property.I could implement every property with protected Reset'PropertyName' and ShouldSerialize'PropertyName' methods. However, this is a bit of a pain in the arse.Is it, generally, an important consideration to ensure that someone who overrides your base class has the ability to change the default values of a property?

I currently receive spreadsheets from clients which include several date fields. Since these are coming from many different sources, the date formats can vary widely (although they will all be US format). It could be "April 19, 2010", "4/19/2010", "2010-04-19", etc. I would very much like to use the DateTime.Parse function rather than having to write my own parsing function--I don't want to have to write out every possible combination of date strings.
The problem is, the DateTime.Parse function includes default values if all values are not supplied. So if the field comes in as "03/2009", since no day was specified, the function will return a datetime equivalent to "3/19/2009" (today's day along with the values given). I cannot use this. If a client provides a date that is incomplete, my program must produce an error, not fill in default values for them. Is there a way to tell DateTime.Parse not to use default values? Or perhaps there's another function that can parse multiple string formats into DateTime type without using defaults?

How do you read the default values from the appName.exe.config file? My application only reads these values on first installation. Subsequently, it reads the updated values sitting in the user.config file.

Looking at the new VB 2010 features, I stumbled upon support for Auto-Implemented Properties.Since I'm working with C#, this seemed quite familiar, but I noticed that VB did add a feature I would love to have in C#: setting a arbitrary default value for the auto-implemented property:I really like the clean usage of auto-properties in C#. This would save us the effort of introducing a backing field and hooking it up to the property everytime we simply need a default value, thereby cluttering up the code unnecessarily.I was wondering why this wasn't introduced in C# as well? What could be the rationale for not doing this? Is a syntax discussion going on, or are there technical limitations to implementing this?

How do I reset My.Settings at run time to the initial default values. I want to do this after the app has been running and the user may have save changed settings. The intention is to reset evering to 'factory defaults' as opposed to the last saved value as done by 'settings.reload'.For example in the property below , I want to restore to the value to '90' as given in the default value. I want to do this for all settings.[code]...

I have a vb.net 2010 form with 22 data bound controls from two tables held in a dataset which is navigated by a bindingnavigator. This successfully adds deletes and updates. However what I need is when adding a new record I need some of the fields to be pre filled out. More specifically I have points balance fields etc which could be any value but will normally be 0 on a new customer so I want to initialize them to 0 when adding new records.

I have an application in which I have two text boxes in which I enter name and age, after I enter the name and age then I click the Add button when I click the add button then the Name and the age should be displayed on the Datagrid contol in the same application. But the data should not get saved in the Database, it should just show the data on the Datagrid contol. And they have told me that its mandatory that I have to use the DataTable object.
And when i click the Commit Changes then only the data should get saved to the Data base...This i can do .

I have a database and a dataset as the image shows in the link, how would i add the values of the colums "amount1" and "amount2" for every row and entry as the user make entries to be automatically displayed in the "total" column. Meaning that every time values are entered in those amount columns, they will be added and the total displayed in the "Total" column.
