View 2 RepliesVS 2010 - On Load (Startup) Default State?
Jan 14, 2012I haven't used VB in decades and I'm restarting with what I thought would be a simple program. I have two fields on a little form, both of which display a date (dd/mm/yyyy). Field1 is an entry field except on load where is contains a date calculated from field2 (which is 'now' upon application load). Field1 is 'now' + 10 days. This is the default state.
Once loaded (with the data described above), the user can input only in field1. Field2, an inactive field used only for display, is field1 - 10 days. After 15 seconds, fields 1 and 2 revert to their default states as described in the first paragraph. I'm getting all messed up with the 'on load' state. I'll start playing with the timer once I get the initial stuff done.

View 4 RepliesHide Form On Startup If App Occurred Because Of Windows Startup?
Jun 20, 2010I can hide my startup form (or make it appear hidden) on startup. I can start my app on windows startup--through registry values--if the user checks a checkbox.
But if the app starts up on windows startup, I want the form to be hidden, so the program can just keep working without bothering anyone. If it starts up because the user started it, I want the form to be showing, because the user probably wants to change some settings or something.
Asp.net - Dropdownlist Autopost Back Remembering The Selection?

View 3 RepliesIDE :: VisualStudio Property Toolbox Not Remembering Last Selected Property Item
Sep 1, 2011I have a weird question and I honestly hope you understand what is happening here: I design my form (using VB.NET) and put on it a few textboxes, comboboxes and a listview. After the design, I want to adjust the TabIndexes for each control on the form. On the right-hand side of the interface is the property box.
I then select the 'TabIndex' property item and enter a number key (for instance 0) for that selected item. I then select the next textbox control and enter the next number (for instance 1) WITHOUT re-selecting the 'TabIndex' property item. As soon as I select the combobox or listview control, the currently selected property item jumps to 'Items' or 'Collections' and does NOT remain on the 'TabIndex' property item. Why is this happening? Everything worked fine and all of a sudden this starts happening. Should I reset the editor settings or how can I resolve this matter?

.net - How To Set ASP Checkbox State With Javascript
May 1, 2012In 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:
function setCheckboxes( state )
{
var inputs = document.getElementsByTagName("input");

Asp.net - Finding All Use Of Session State?
Feb 3, 2011I'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

Asp.net - View State After Postback VB?
Apr 12, 2011I 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?

Check For Program State And Act Upon That
Aug 15, 2011Here 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.

Checking State Of DNS Server
Dec 6, 2009My 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.
Creating The Three-state Checkboxes?

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?
DataRepeater - Set Checkbox State?
Apr 13, 2010im 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!
