Loop Through Each Button To Check If They Are Enabled Or Not?
Jun 10, 2012
I want to do a For Each loop where i can check whether each button is enabled or disabled. If the button is enabled then i have to obtain the values in the tags for each button. I have 26 buttons each containing different values (cash prizes).*IMPORTANT: this code needs to go under the button so every sixth time its pressed it checks the buttons.
Pseudo-Code:
btncase1.tag = 5
Begin while statement to go through each button
Check each button to see if it is enabled
[Code].....

I am trying to check whether the button is enabled or disabled. I am doing the following
Assert.IsTrue(Browser.IsEditable(button))
but it gives me error that expression does not produce a value. Any one know how to achieve this. Currently I am using VS2010 MStest in vb.net.

Is there any way to check from .NET if windows update is enabled?
I want to prompt the users every time they log into my app that their computer might be at risk and give them a link to windows update website (or windows update application from control panel).
Preferably it should work on XP, Vista and Windows 7. Maybe there is a registry key or even better an API?

In my application I have more then one form/dialogs, of course. My start up (main) form is called "StartForm" and when I want to access to some other dialogs, I open up dialog and I put StartForm on ".Enabled = False" so that user can't access to that form even if he click somewhere on it (StartForm is maximized to full screen and dialogs are small so StartForm can be seen in background when you open dialog). Ok, this works fine until I click on my application "link" in task bar...then, only my StartForm is visible and it's ".Enabled = False" so I can't do anything...I must kill process in task manager. Same thing happens when I open some other application and then come back to my application.

I have a Nag Screen that I am creating, and I am wanting to create a delay before the OK button is enabled allowing the user to proceed.
Is it better to use a Timer event or would a 'For I = 1 to 20000"
loop be the better option.
All this timer would do is Enable the OK button, thats all.

Alright I'm very sorry. This is a very Noobish question and I thought I could figure it out my self but I am haveing alot of trouble.Okay so I have 5 Checkboxes. When All them are checked I want Button1 to be enabled.And if any Checkboxes get unchecked after they where checked I want button1 to be disabled.

As i'm learning more and more about developing ive just got my head around creating classes and modules, i started wondering about something to do with configuration of applications where deployment is in a more diverse environment say in a company where different branches dont need access to all parts of a program, so i thought id throw the question out there in a basic sense and get some feedback. so i can go off and do some more reading and learning.
So the scenario in my head is like this.
So we have for arguments sake FrmConfig which is the master configuration form, then we have FrmMain which is the root menu our application general user interfaces with. So here based on what options are checked as enabled in FrmConfig effects what controls (like buttons/menu options) are enabled in FrmMain.

I have a Form with a Group Box with a number of check boxes within it, each check box has a text box next to it for the user to enter a number. I wondered if it was possible to loop through the check boxes within the Group Box to find out which are selected and output the value in the associated textbox next each checkbox as it loops?

Suppose I have an IEnumerable such as a List(TValue) and I want to keep track of whether this list is being accessed (to prevent issues with, say, adding to the list while it is being iterated over on a different thread); I can always write code such as the following:
Dim List1 As New List(Of Integer)
Dim IteratingList1 As Boolean = False
' ... some code ... '
[Code]....
(I realize this code is very arbitrary, but it illustrates what I'm talking about.)
My question is whether there's a better/cleaner way to perform this check than by manually updating and accessing a Boolean, as above. I feel like there must be, but, to my knowledge, there isn't any IEnumerable class with a built-in "I am being iterated over" method or property. And writing a new class that implements IEnumerable and contains such a property seems like overkill to me.

I'm using a loop condition to check if there is null value in the columns, then remove it.
-Original author
[STart:]
For i As Integer = counter To dt1.Columns.Count - 1
For x As Integer = 0 To dt1.Rows.Count - 1
if some condition then
something = true
[Code]...
Sometimes it runs correctly and sometimes even though when i becomes greater than (dt.columns.count - 1), it still executes the for loop and throws an error that there is no column with that index. I must be missing something here but I'm not able to debug the issue.
