Is there built in .NET functionality for making state abbreviations out of state names?
I know the function wouldn't be difficult to write, but I would assume that MS has thought of a more efficient way than the following x50[code]...

View 21 RepliesI'm setting up a program where I would like the user to be able to select a state from a combo box. I can not figure out how to allow to select the abbreviation from the drop down list and also allow them to type a letter and it will select the state from the state or just allow them to type the full abbreviation that would match what is already in the list. It is supposed to be in the drop down list style. I would also like to confirm that the user has chosen a state before allowing them to click a submit button but I'm not sure how to go about confirming it.

I am doing work for a client who has lost the source code for one of their VB.Net WinForms applications. The assembly they have is not obfuscated at all. I am trying to recover as much of the source as I can as C# source and have tried several tools for decompiling assemblies, including Reflector, ILSpy and JustDecompile (all the latest versions), but they all produce code with a huge number of errors in them. Because of the large number of errors in the generated code, I am going to ask about the specific errors (in different questions), get more directed answers and in this way try shed some light on why all the tools are having difficulty decompiling this assembly. This question pertains to the fact that the code generated by all these tools always have a large number of invalid member variables (fields) such as the following:
private short $STATIC$Report_Print$20211C1280B1$nHeight;
private ArrayList $STATIC$Report_Print$20211C1280B1$oColumnLefts;
private StaticLocalInitFlag $STATIC$Report_Print$20211C1280B1$oColumnLefts$Init;
why the generated code has these invalid member variables?

View 3 RepliesIn a VB.net app, I have several checkboxes created with regular ASP controls, i.e.asp:CheckBox ID="cb3" runat="server" Checked="true" />I'm trying to implement a "Select all/none" functionality but I'm having a few problems. The Javascript is not changing the state of the checkboxes in Internet Explorer (v9). I tried debugging with IE's dev tools and the checkboxes are definitely getting their checked property set to true. (Also tried setting to "checked".) Here is the JS:

I'm looking for some smart ideas on how to quickly find all usage of session state within an existing asp.net (MVC) application.
The application in question was the subject of outsourced development, and has been running fine in production. But we recently realised that it's using InProc session state rather than (our preferred route) StateServer.
In a small scale test, we switched it over to StateServer, and all worked fine. However, when we deployed to production, we suddenly experienced a large number of errors. I'm not sure if these errors were caused by this change (they were actually complaining about database level problems), but removing the change allowed the application to function once again (this may have just been because it caused a recycle to occur).
So before I try switching it again, I'd like to perform a thorough audit of all objects being placed in the session (I'd previously taken a quick look at a couple of controllers, and they seemed fine). If I had full control over the code, this is the kind of place where I'd just comment out the class (to compile and find the various ways of reaching the session class), then comment out the accessors, hit compile, and visit each error. But I can't do that with built in .NET framework types.
I decided to try using Reflector. I've analyzed the "Used By" for each of the following:
System.Web.HttpSessionStateBase.set_Item(String, Object) : Void
System.Web.SessionState.HttpSessionState.set_Item(String, Object) : Void
System.Web.SessionState.HttpSessionState.set_Item(Int32, Object) : Void

I have a label's value that is posted back from a previous page and I want to use this label to do a simple calculation in the current page, but when I do the calculation the page (refreshed) the value of this label and automatically deleted the value (Since there would be no value in postback when it refreshed).
Here is the code behind file:
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Label2.Text = Request.Form("Hidden1")
End Sub
and here where I want to use the label
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Stotal As String
Stotal = Val(Label2.Text) * 10
Label3.Text = Stotal
End Sub
How can I save the value in the page via view state or any other method?
when they say static classes should not have state/side effects does that mean:

Here is, basically, how my application works:
When windows starts, my app starts. Whenever my app is running, it hides the desktop, taskbar, etc... When a button is clicked in my application ("Start program"), then my application will set its visible property at false and another application will start.
Everything seems to work perfect except I need a way for my application to set its visible property back to true, but only once the other application that was started earlier, is closed (no longer running.)
My thought was that I could use a timer to check for the applications state every so many seconds:[code...]
I have 2 concerns with this:
1. A timer checking this every few seconds will invoke unneeded stress on a computer since they are running for sometimes very long periods of time.
2. There is a better way to accomplish this that doesnt rely on a timer.
Why does this not work?

My ISP's DNS server goes down all of a sudden sometimes. This is very annoying while surfing the internet. So, I'm trying to make an application which has the following characteristics :
Runs in system tray
Pings the server periodically
Notifies when the server becomes unreachable/active
Now, I know that the existing workarounds are to use OpenDNS or ping <IP Address> -t in command prompt. I don't want to use them... the reason being that the former gives much higher pings than my DNS & for the latter, I'll have to switch windows.
I can create a checkbox array as follows
Code:
For n = 0 To 13
With (chkboxarray(n))
.Tag = n + 1 ' Tag of button
.Width = 35 ' Width of button
[code]....
But when I run the program the checkboxes only display 2 states (they do work as 3 states). what I am missing to display the "Indeterminate" state?
im trying to figure out how on earth to set a checkbox on a DataRepeater row to true. Nothing ive tried seems to work. Ive searched all over, and all i seem to find is ways to check the state and in ASP.
Text boxes would be:DataRepeater1.CurrentItem.Controls(
"textbox1").Text = textbox2.Text.However, checkboxes wont work in this way. DataRepeater1.CurrentItem.Controls("Checkbox1").Checked = True"Checked is not a member of windows.forms.control" - ive tried various things in order to set it to true/false, but whatever i do doesent work. I expect its going to be something stupidly simple, but its those things that annoy the most IMO!
