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?
Having A Grid Hold Its View State?
May 29, 2009I have an Obout grid that I have been trying to work with and I put all of their code in my site so that I could have my grid stay expanded when the page does an automatic refresh.How or what is the correct way to code for a If (Page.IsPostBack) code.Next is there an online free convertor, translator, for javascript to VB.NET; if not is there someplace that I can go to where they will explain the different meaning of the javascript in comparision to what it would mean in VB.Net (such as var I think means dim or it could mean something else I am not sure.)Final is there a good source on grids and how they work with a view state or a session? But it needs to be basic as I am still trying to understand all three of those processes.
View 5 RepliesTurn View State Off But The Fact Of The Matter Is When Data Is Posted?
Jul 14, 2010I have a grid view with a nested text box in it. I would like to turn view state off but the fact of the matter is when data is posted, the text boxes inside the gridview aren't available (there are no rows in the gridview on postback)I am using ASP.NET 2.0 so would this fall into control state, not view state?
Sample ASPX code of the gridview:
[Code]...
Control's information is not stored in the View State (for things like selected value and .text etc.)Control state, introduced in ASP.NET version 2.0, is similar to view state but functionally independent of view state. A page developer can disable view state for the page or for an individual control for performance. However, control state cannot be disabled. Control state is designed for storing a control's essential data (such as a pager control's page number) that must be available on postback to enable the control to function even when view state has been disabled.[URL]..

View 1 RepliesDisable Form's Control(View Only)?
Jun 21, 2010I had a form (says form A)with control on it, 2 buttons with text "View Process Flow"(Button1) and "Manual trigger Process"(Button2). Both button will load and shows Form A in Panel1 in Form1, but button1 will let user to see the action but block them on clicking on it, button2 will let User see and clickon the control.
In other software, I can use a transparency button or form block User by acess formA(so, they can see,but not click), But VB2008 transparentcy option kind of idiot(Or i dont know how to use it?)seem it just change the control back color to parent's backcolor(totaly useless, and the "tranparen key" as well)
I cant disable control cause it will stop the animation, only ways i can think off is add in a IF statement in every button, so it will do nothing when viewing = true.
Disable Appearance Choices From Designer View
Dec 14, 2011I'm building a game using the traditional form view on VS2010 and I'm trying to change the colour of a label's text depending on its contents. I believe I've coded that fine, but the problem is that the settings for the label in the designer view pane are overriding my code!Is there a way to disable certain options in the designer view so that my code can work?

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.

View 3 RepliesProgramming Theory - Save The State Of A Program
Mar 23, 2012What is the best way to save the state of a program. Maybe that is not the right way to describe it but, what I mean is almost any application you can input a whole bunch of data make selections and choices and then save these in files unique to the application your working with.
For the time being I will ask my question in term of VB.NET since it is what I am currently working with. I understand the use of the stream writer to write data to a file (any file extension can be used even your own made up one) and then you can later open the file with the stream reader and load the saved application state. At least that is what I know how to do. Are there other ways to approach saving the state? In my case I have a dictionary that is defined through user input to store a lot of data and I am trying to find the best way to save the dictionary so I can load it again.

.net - Creating A Program That Runs As A Service And Submits A State To A Database (over The Internet)?
Dec 2, 2011What I am looking to do is write a VB.NET program, as a service that reports anything on client1 that I want (say the fact it is online) to a database on the internet, so I can look on management1 and see the online status of the machine (assuming management1 has a connection to the online database).
What is being reported doesn't matter, what I am looking at is a starting point to create a system like that. I have googled obviously and come up with nothing, I'd just like a "starting point" or some documentation to look at for creating something like this. The service doesn't look too difficult but the periodic reporting of online status or ANYTHING to any kind of database is not something I am sure how to deal with.
I already have setup a VBS that reports information to an ASP script that then places it in a database but I don't know how I would create say a "keep alive" connection for a vb.net service.
Error# 18456, Severity: 14, State: 8. Coming From Visual Basic Program
May 17, 2010I've been hired at a company to fix some bugs and make some improvements to their in house programs. The program I am currently working has been written in Visual Studio 2005, in Visual Basic specifically. The program is used to connect to a database on a server and provide various information. However, I have run into a snag where the program will refuse to connect to the database when it using a user account and password that has been set up on the database. When I look at the logs i see it is giving the error as stated above, however, I have double and triple checked the password both on the database and the one hardcoded into the program and they are identical yet it still logs that there is a password mismatch. Has anyone run into this problem or figured out a solution towards fixing it, I will be much obliged.
