Programmatically Checking/Unchecking A Checkbox In Windows Form
Jan 10, 2012
I have two checkboxes in a windows form, one is called New Assumption the second is called Edit Assumption. What I want to do is that if either of these checkboxes are checked then the other should be unchecked.
I have tried using the CheckedChanges event, CheckStateChanged event and Click Event for each of these checkboxes and these events dont seem to be activated anytime I click the checkboxes.
What event and code should I use to uncheck and check checkboxes programatically based on which checkbox a user clicks on?

OK, to make a long story short, programmatically generated data is taken back to the original page and the goal is to have this information cause checkboxes (hard coded into the aspx page) become checked.
Using feedback, the exclamation below confirms that I want the found control ctl to be checked:Dim ctl As Control
For Each ctl In form1.Controls
[code]....
I'm not sure what to put for XXX and my gut feeling is this is really easy. ading my question. I went through pages of search results on "VB Programmatically check checkbox" and found pages that should have had an answer that worked

I am trying to create a small application that will tell me if a website is up and running. This application will monitor if the site goes down. The problem is that there are several websites sharing the same IP address, and I cannot use ping to monitor it for the same reason. I do not know what type of code can I use to query the availability of the website. I read about webRequest and webResponse but I do not know how to get the response information that will tell me if the site is up or down. The code should be able to tell if a site like "mundo.reporters.com is accessible. That is the only thing.information to point to a potential solution will be more than welcomed.
The server is hosting 8 websites that share the same ip address, and I need to constantly monitor if they are functional.

Im doing a small project in visual basic which involves lighting up leds through the parallel port and turning them on and of. each led is controlled by a checkbox on my form and they only come on when the checkbox is checked.
what code do i need to use to have the checkbox checked when a key is pressed but when the key is released the checkbox is unchecked i have already tried keydown which will check the box when a key is pressed but will not uncheck it when the key is released
If e.KeyValue = Keys.A Then
CheckPin1.CheckState = CheckState.Checked
ElseIf e.KeyValue <> Keys.A Then
CheckPin1.CheckState = CheckState.Unchecked
End If

What would be the syntax to check inside a visual basic form panel for checkboxes and find which are checked? I understand how I Could use a for loop and an if statement, but I'm confused as to the syntax to check for each checkbox. for example:
Dim i As Integer
For i = 1 To 10
'Here is where my code would go.
'I could have ten checkboxes named in sequence (cb1, cb2, etc),
'but how could I put i inside the name to test each checkbox?

I have a question regarding the checkbox. Here is the scenario: I have three groupboxes which I have initially set as invisible. I have three checkboxes out to the side. If I check a checkbox, is it possible to have one of the groupboxes become visible just by checking the checkbox and nothing else. (I mean without clicking a button or anything, just clicking the checkbox and then having a groupbox become visible).

I'm having a problem unchecking a listview checkbox where the listview is displaying items only. If the listview item is not selected, I can uncheck the checkbox using e.NewValue = CheckState.Unchecked when I do not want the user checking that particular item within a listview.itemcheck sub. However, when the listview item is currently selected, the checkbox will remain checked. I even did some displays (using msgbox) within the listview.itemcheck sub to show that the listview.item(n).checked = false, however, after the sub procedure completes, it changes it back to checked. I even attempted to set e.NewValue = e.CurrentValue with no luck.

I am trying to find a way to accurately verify if a Windows 7 machine is currently using an active license and activated. I believe I can initiate a 'cmd.exe' command to run a cscript (slmgr) and parse that information but that seems like an inefficient method.I have came across an unmanaged windows API called SLGetGenuineInformation [url] however I am not familiar with how to call this in VB.NET or what the variable types should be. I believe VB6 came with some sort of APIViewer that Visual STudio 2010 does not seem to contain.

i don't have any code to provide as i have no idea where to start.

How to disable Ctrl-Alt-Del in Windows 7 when the application loads? I'm looking for an example that disables Ctrl+Alt+Del when the app starts, and enables the combination again once it finishes.I found an example that disables the combination on Windows XP, however it doesn't seem to work on Windows 7. Why? Is it not allowed on Windows 7 to disable Ctrl-Alt-Del?Also, I'd like to know how to run an application as admin on Windows 7?

I wrote a small app we use on our computer to keep them running optimally and do some utility things (delete temp files, defrag drives, clean registry, backup my docs to the server, etc). One of the options I ahve in there is "Reset Windows to Defaults" and the objective was to setup windows how we normally would set them up before we give them to our users. So if a user messes with all his/her settings we can click this button and reset it all back. So far it resets IE settings, changes Window Explorer views, puts all the default icons on the desktop and turns off desktop cleanup, etc. Well one of the last things I want to do is change to the default Windows XP theme and apply it. After a lot of searching the internet I found this:
[Code]...
It does reset colors and stuff back to the theme. The problem is if a user has "Windows Classic" set and this is run it does apply the theme.....mostly. Things like dialog boxes stay in classic while the menu structure and desktop go the XP style. If you go into display properties it still shows "Windows Classic" but under Appearance it shows "Windows XP" which leads me to believe even though this function is for themes its actually just applying the appearance and not actually setting the theme.

Windows resets the IDLE time every time the user touches the keyboard or the mouse. My application needs to reset the IDLE time at specific moments, but how to do this programmatically.
The following does NOT reset the IDLE time using VB, C# or QT4.
- Programmatic mouse movement / click.
- Programmatic keystroke.
Somehow Windows knows these actions are simulated. How can I reset the IDLE time?

If you edit a service in Windows 7 and go to the Log On Tab, there is an option to "Allow service to interact with desktop". I'm trying to ensure that it is set for a certain service using VB.NET.
Note: Doing this during the install of a program is not an option. It has to be done at run time.
