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.
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?
View 24 RepliesI 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.

View 2 RepliesLooking 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?
View 4 RepliesHow 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]...

View 1 RepliesI'm using a pattern of buttons verticle, & horizonal, to produce a 2 dimensional matrix (6 deep, 25 wide .) The sequence is repeating, but offset from horizonal line to line. the values are 1 thru 12. there are corresponding files in the "My.resources." file carrying names related to the buttons. If the "my. Resources" filename is say.., "1,3,4,6,8,9,11,12 " & the buttons pushed have produduced the string "1","4","6" then the prestated file carries all these values, and therefore should be selected. All integers of the textbox list must be present in a "my.resources" file to show the file. There will be multiple files in the resource file that will fit. (My ultimate intention is to show all files that fit, somehow. I'll have to, eventually. I'm still writing this, and changing it constantly. )the question is, "How do I get the computer to link the textbox integers to the resources files?

VBbasic 2008: I have a readonly textbox in a panel. The background color needed to be change to white for a more "readable" text. The problem is when I set the panel "enabled= false", the only control that does not look "disabled" is my textbox because it stays "white"! Even if I set the textbox to disable, it stays "white". How do you change the default backcolor of a readonly textbox instead of "forcing" it to white? Is it possible?

This is contained in a timer event that shows how much it would cost the player to purchase all of the items. This works as intended, until the text box is blank. Each "section" draws information from one of 16 text boxes. My question is this: Is it possible to have each text box to have a "default" number that gets put into a text box when it is empty. This is needed to be done for all of the text boxes, so either a loop or a non specific code slice would be preferred.
