VS 2008 For Each In ListBox - Setting Time Interval?
Apr 22, 2012
I have this code in one button:
For Each x In ListBox1.Items
Label1.Text = "Status: Loading IMDB page..."
Dim str As String = x
Dim MOVIESNAME = str.Substring(str.IndexOf(""c) + 8)
[Code] .....
Is there an option to set a time interval between each check? Because it will load the page (it's not google, it's my personal website with some information needed) and it need to be fully loaded till it gets the information then it would do another check for another listbox1 item. Like.. maybe 5 to 10 seconds is enough..
Webbrowser1
Dim strCDRack() As String
Dim cdList As String
'Dim i As Integer
cdList = WebBrowser1.DocumentText.ToString
[Code] .....

I don't know much about vb.net so I'm hoping this is something that can be done fairly easily. We currently have a system where valves are fired by checkboxes (representing each valve) being checked at certain intervals and when the last valve is switched the timer restarts in order for the sequence to repeat itself. We would like to be able to have a textbox in the form where we can just type in the interval at which the valves (checkboxes) switch without having to change the interval manually in the code each time we want to change it. Currently in our code we just have a set interval. Here's the code:

What would be the best way to run a subroutine over and over again every X seconds. I want to avoid creating an infinite while loop to do this because this sub needs to be called repeatedly while the rest of the program is still active and responding.

I am using Visual Basic 2008 for a Windows Form application. I have a PictureBox on the form that I need to display a series of 12 JPG files, one every four seconds. For the life of me, I cannot seem to figure out how to get the Timer control and its Click event to work.
In pseudo code, I need something as simple as the following:
1. show JPG #1 in picture box
2. 4 second delay
3. show JPG #2 in picture box
4. 4 second delay
etc.
I have a Timer on the Form set with Interval = 4000. I have a PictureBox. I have all the images in the Project. I am embarrassed to say that I have spent 4-5 hours searching the Web for sample code or something helpful, but am still stuck.
All the elements are there. It's just a matter of understanding how to pause the image displayed in the picturebox for 4 seconds before moving onto the next image in the series.

I have three settings Pleas,DocketSheets,AllTrays (strings). How to I set the value and save them for ever?
I've tried.
My.Settings.AllTrays = "Tray1;Tray2;Tray3;Tray4"
My.Settings.Save()
but it says that AllTrays is readOnly. Are the settings only retrievable and not settable or updatable?

I have a quesion about using the timer1 function. I am a complete virgin when it comes to programming, so please be kind. I have a project that is using an NCD relay controller to control linear actuators. I want one relay to turn on and then stay on for 10 seconds and then turn off. I set the timer1 properties to enable with an interval time of 10000. I am programming a button to turn on the relay then wait 10 seconds then turn the relay off. All that happens is the relay comes on then off immediatley. I have tryed to do this several different ways with the same results. It is though the timer1 is not getting recognized. So my main question is, what steps am I missing, and how do I get a delay of 10 seconds before the program recognizes the turnoffrelay command?

have another problem trying to solve again I am trying to add a line into a listbox in this format time item (10), so, e.g. 4:00 Item1(10) So when the next item is added into the listbox and so on, it will look something like this
4:00 Item1 (10)
4:10 Item2 (15)
4:25 Item3 (20)
The time is a Date, and the minutes to add on is extracted with regex. I was able to add the items like above with hardcoding but ain't successful when i try to do it in a shorter way.

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)?

I have been making an online role playing-game in VB2008 and inside the gameloop for the client there is some code that "smoothes" out the movement (instead of it being choppy from tile to tile.) It works pretty well but I'm having problems figuring out a math formula to get a good frame timer interval to set how fast the frames change based on how many pixels they can move per loop.Testing stuff out I found that 250ms is an ideal frame timer interval for 1.0 pixel movement per loop. If I were to double the movement step of pixels by 2 lets say (2.0 pixel step per loop) I found that the frame timer interval should be around 125ms. How can I get the frame timer interval by the movement step of pixels? In cases where the movement step can anything between 0.1 to 4.0 pixels.

What I am trying to do is allow for my objects to know when their data has changed on the database (so they are able to raise an event to let the user of the object know about the change).After following several tutorials on how to get SqlDependency working, I have finally managed to get it to let me know when something changes (although it also appears to let me know when I make the initial connection to it too, but that isn't a problem as I can work around that).The function that I have which sets up the SqlDependency is;
Public Function getMembers() As List(Of User)
Dim conn As New SqlConnection(_connectionString)
Dim sql As String = "SELECT UserGroupUserID, UserID, GroupID FROM dbo.xtblUserGroupUsers

Basically, my app has the main form and a windows form "splash". Let me explain, this "Splash" is a WINDOWS FORM, not a splash form; its just named splash because I want to use it for that reason.In my project settings, my main form is my startup, and the splash form is my splash. This splash form has been coded on a timer for 10 seconds, but when I set the splash form as the splash setting, the form shows up for 1 second and goes to the main form.What I need is to edit the splash setting time from 1 second to x# seconds (preferebly 10)

I am using Visual Basic 2010 for a project.My project requires to place a TRANSPARENT button on top of an image (placed inside a picturebox). for that to work, i need to set the button's parent to the picturebox. Is there a way to do that in design time? I cannot find anything on the property tab. The reason i want to set it on design time is because my project will have a motherload of buttons and it will a pain to code the parent change....

In VB6 I would simply retrieve the user font setting from the .ini file, load into variables and then apply to the appropriate control.
text1.fontbold = userfontbold
text1.fontitalic = userfontitalic
text1.fontunderline = userfontunderline
etc.
I'm struggling to understand how to do this vb.net The following code works, but sets all three at one time
Text1.Font = New Font("Courier", 10, FontStyle.Bold Or FontStyle.Italic Or FontStyle.Underline)Since the user can have many different combinations of settings, I would like to be able to add just one of these properties at a time, but can't seem to figure out how to do it.

I'm using LINQ to Entities to generate typed result sets in VB.Net. I've got a generic Report class as follows:
Public Class Report
Public Property Name As String
Public Property SQL As String
Public Property Type As String
End Class
Then in the calling scope I want to have code that does something like:
' create my data context
Dim context As New MyAppEntities
' get a report object out of a dropdown list
[Code]....
So far I'm finding that .Net won't let me set the type in the (Of Type) clause on the fly at runtime.
Does anyone know how to do this?
I've tried changing the Type property of the Report class to an object of type Type, but that doesn't work either.
BTW, I know there are alternative ways to accomplish the same thing, but I'm working with external constraints that make this what I've got to work with right now.
