I have a form that is currently working how I want it to. I want it to update every 30 seconds. I have set the time to 30 seconds but can you verify I have the correct code in my timer? Do I need to reconnect to the database every time it counts down from 30? here is my code that runs on form load...

In a vb 2010 project, I have 2 win forms: Form1 and Form2.
In the Form1 class there is a server-based timer: when the "elapsed event" fires, then I update the text of a Label1 on the Form2. A very simple code:
I have an MDI form, and all of its children have a timer control. I also have an options form where the user can change the automatic refresh interval, which is loaded from the parent. The interval is stored in My.Settings.UpdateInterval as a Double.What is the best way to update all of the timer interval of the Children? Can the Children listen for an event in the parent form (UpdateIntervalChanged)?
View 2 RepliesI have one form, which the user enters upto 5 websites then clicks go - I have on the second form, the one with the webbrowser. timer which checks if the web browser is busy then either a green light or black image will be shown along side the assocaited input box on the first form. I am finding it impossible to feed variables into the clock through ByVal, like I would a subroutine or function.

I'm working on a windows toolbar that I'd like to fade when the cursor is pulled away. I'm not quite sure if there is an event to check for Mouse Movement OVER the title bar though?! (my code below fades the form when I put the cursor over the forms title bar).

I have a timer in vb.net and it's interval is 1000ms ,. i have placed in it's timer_tick event a code that will print screen the screen and save it to a database.The problem is when i click outside of the form, or loosing the focus of the mouse to the form containing that timer/printscreen, the timer stops. As a result the printscreen also stops.here are it's properties:
generate member = true
interval = 1000
modifiers = friend

i have a MDI application with parent and childforms.
i have a global timer in a module that makes a com search and writes the result to a parentform status strip label.
the problem is that the label do not change.
i have tried the following:
1) on timer.elapsed
parentForm.statusstriplabel.text =...
2) to create a delegate and invoke a parent form function
3) to create and raise an event
although all 3 seened to run the label didn't changed.
the timer was created in a different module than the parentform class for many reasons.
one of them is because i want to access the timer.start , timer.stop from all the childforms
when i tried a local timer to paretform worked perfect but i couidnt start and stop it from the childs
Currently, I'm testing the timer function.
I used the following code for my form:
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 2 RepliesIve managed to dynamically create a form, and dynamically create a timer, but i have not been able to create the timer on the dynamic form. Specifically, i need to be able to have the timer itself create another form with a timer. (I realize that this would create a new form every interval on the timer, that is what i want to do)
1. A way to add the timer to the dynamic form, and maintain the timer sub on my main form.
2. A way to create the whole thing over (dynamic form and timer) through the previous dynamic form and timer.
I was thinking i could use a collection/array to store the forms and timers, but i'm still having trouble figuring out how to add entire forms or timers into a list. (A timer is not considered a control, so i cant use a controlcollection...)
Heres my code;
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim frm As New Form
[Code]....
*EDIT* Btw, my idea was to use i as a variable that increases every time a form is created, then insert the form into the array, with i as the integer. i just need to know how to create a new form with a different name each time. (as with timers)
For reasons that are beyond my control, I have three Projects. Projects A and B reference project C. Project A references project B so that it can open a large form in project B. I now need to open that large form from project C, but VB won't allow me to add a reference from C to B because that would create a circular dependency. I found a way around it, though. I created a Timer in A, and when I opened C from A, I passed in that timer. When the user performs a certain action, I enable the Timer from A, and this causes C to open B for me.

View 1 RepliesI am creating AutoSave functionality for an application. Its an mdi application. it needs a seperate form where the user can turn AutoSave onoff and set the interval in minutes for it to execute. The users values for these i plan to saveupdate etrieve into my.settings.
I plan to put a timer on the form that needs to be AutoSaved. If the user turns off the timer from the options form, how would i go about stopping the timer on the form that needs to be saved? Should I change the timer to be "Shared Friend" and access it directly from the options form or what?

I am currently developing an application in which I would make a form full size automaticly.On the location where I set the time parameters, lets say, I want an event to occur every 2 hours, in which the event would be a form becoming full-sized and, on that form a clock which would show that the form will resize on its original state after lets say, 15 minutes.And also I would like to disable the Windows Start keys.I tried some codes but they were for an event if the key is pressed.For this I need the keys to be disabled as soon as I start my application.For the full size form I have used this code:
Me.Height = My.Computer.Screen.WorkingArea.Height
Me.Width = My.Computer.Screen.WorkingArea.Width
Me.WindowState = FormWindowState.Maximized
Me.FormBorderStyle = Windows.Forms.FormBorderStyle.None
I have been battling with resizing a form in code, using either a timer or a for loop. When I say resizing, what I want to do is create the effect of a rolldown/rollup window. On my form, I have a groupbox with search criteria options, and underneath the groupbox, I have a datagridview with several buttons.
The effect I'm trying to create can be seen in Windows XP Security Centre; when you open up the security centre screen, you have your firewall, automatic updates and virus protection areas; to the right of each, there is a small round button, with either an up or down arrow, depending on whether the section is rolled up or down. When you click the button, the section rolls down or up smoothly.
