VS 2005 - Function Based On Timer?
Feb 9, 2010
I can't seem to get one of my functions to work based on a timer. Every tick of the timer, I'm trying to call a function which will start periodically taking screen shots until the 'Finish' button is pressed. However, I've run into numerous errors and wondered if anyone could give me any insight or suggestions. Here is what I have so far.
[Code]...
One of the errors included "Public Sub RunAC() does not have the same signature as delegate". This might be really obvious, I'm a recent Computer Programmer / Analyst graduate with intermediate VB.net experience.

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 am using the Process.Start function to open a program based off a registry value. It works, sort of. Here is the snip of the
Imports System.Data.SqlClient
Imports System.Console
Imports System.Configuration
[Code]....
The program opens with the correct registry value, but the program itself does not run quite right. This program feeds into Intergraph and brings up the selected drawing, but there is a feature of intergraph that doesn't work. If I manually start ( double click ) pdsicon.exe the program works just fine. It only when I call the process that it doesn't work quite right.

In a piece of code I am writing I am trying to change the text of a label in my form based on a timer. I have MANY other labels that are all updating in their own subs and when I try to add any new labels(in any sub) to update it wont. I am using Label.Text = counter where counter is a string that is changing. I have tried refreshing the form, Label.refresh() Label1.Update()....The only thing I think it could be is that the redraw is being held up by other calculations on the cpu. How can I make the label text change and update properly?

I often think of classes and modules as "global" variables or variables you can use any where in your solution/project. can you make global timers? I basicly want to make a farming like game but the plants will grow based on a timer. So if the player closes that form the timer needs to still tick. So can I make global timers so the timer would not have to start over if the form is closed and reopened?

I am facing another issue. I want to associate a timer to my function. Actually what i am doing is that i am tryin to store certain values in a database. A function is such that it calculates 5 values and stores them in a database. While storing them in the database it displays them in a textbox on the form. Now i want to display them one by one which it does. But it does it so fast that i can only see the last value that it enters in the database inside the textbox.
Can i make it show all the values slowly one by one.
Private Sub dbInsert(ByVal strfile As String, ByVal hashoffile As String, ByVal p As Integer)
'parameter to the above function (ByVal strfile As String)

I am making a game that involves using the arrow keys I have been using the keydown function for the form but when i use it now all the timers seem to stop. this was my previous code for the arrow keys using the keydown function:
If e.keydata = keys.up Then
If pbxship.Top <= 77 Then
pbxship.Top += 10
Else
[Code]...
but this does not do anything like the keys are not pressed, does anyone know how to make it work or a different way to do this in a timer

What line of code would I need to use the timer function just as a delay, so like as lines are being executed, once it gets to this timer it waits for say 1500 milliseconds before execution is continued.

how to use the timer to control the blinking? Cuz i tried to stop one timer, it did stop this timer but if i didnt stop the timer 1, both timer 1 and timer 2 will begin although the data is in different entity. By right if the alarm comes in from block 2, only block 2 button will blink, like wise if the alarm comes in from block 1, only block 1 button will blink
the below is my code:
Imports System.Data.SqlClient
Imports System.data

I have successfully set up a timer in visual basic, see the code below. My timer uses case statements and at specific case/time it calls a function, 'ShuttleA'. 'ShuttleA' function, is a function that 'getskeystate', which inturn from the user interface tallies a response in a text box. My problem is that the program runs fine when calling the function at eg; at 10 seconds, case 10. But I want to be able to call the function e.g., at 8 seconds to 11 seconds. Or create a tolerance of e.g., 1 second either side of e.g., 10.
PrivateSub Timer1_Tick(ByVal sender As System.Object,ByVal eAs System.EventArgs)Handles Timer1.Tick
Dim secondsAsInteger
seconds += 1
Label1.Text = seconds
SelectCase seconds

file_send is the function of dll .
prg_Timer is the timer control .
Prg_bar is Progress bar control.

I was trying to use the System.Threading.Timer to run a function every 250ms - but I'm finding it difficult to cancel the timer from within the callback function. I can't seem to find a reference to "this" (js has this - it's so nice). At any rate - how could I start a callback running 250ms from now - without a timer - and then if I want to continue it again do another start for 250ms.

Basically, I want to create a timer for each row of data that will get returned by a SQL query:
SELECT * FROM Projects
I would want the timers to be called "Compteur" & ROWID. This really is necessary.I need them to have different Ticks and so that some can be enabled all at once. Basically it is for a project tracker to count the time you are working on the current project. However you could indeed work on many project at the same time.

In short I want a call a function jAlert() from jquery.alert.js file in a .aspx.vb page.. More details below
"When I click on "update page" the control goes to "ActionRepeaterItemBound" on code behind and then to my action.js page and this way I am able to add attributes and use them while calling my jscript function. However when I click on "Submit Update", the control first goes to action.js and then to "ProcessAction" on code behind. So I am not sure how I need to add attributes before the control goes into action.js."
I have a file jquery.alert.js which have functions like jAlert().
I have a file .aspx with part of code as below
[Code].....
My aspx.vb page has a function as below where attributes are added to control and are used in a page action.js to call the jAlert function
Protected Sub ActionRepeaterItemBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs)
I want a similar logic to be performed on my LinkButton "CurrentActionCommit". How can I do this?

Say I've got the following variables:
Public Shared x As String = "100"
Public Shared y As String = "text"
Public Shared z As String = "something"
[Code]....
But this doesn't do what I want, naturally. What I want is that my function giveVar returns the value of the variable that holds giveVar. For example I call giveVar("x") I want my function to return "100".
Of course this can be done by a Select Case but thats not what I like to do. Is it even possible to call a value based on a string?
[edit:]
Namespace i18n
public NotInheritable Class Settings
Public Shared LanguageCode As String
[Code]....
I think this works so far, BUT I get the following error on the CallByName(Me, varName, vbGet) at the Me : "me is only valid within an instance method"

Just a small question here, I'm using a timer in my program which I set to change a variable called "time". I want to put a few if functions in i.e. if time = 5 then change label colour or something like that. Can I put these if functions into the form_load section of my code or will this cause problems? Is there somewhere you can put code without needing to click buttons or anything like that?

I have done this in Php with a function before. I just don't know how to do it in VB.I have a character sheet creator for a game I am making. What I am wanting to do is write a single function, where in you click on a button and it will pass the text box name (so that it knows which text box to edit), as well as the value inside of the text box (to make sure that the new character stat ceiling is taken into account).
Private Sub Button_Click
AddtoValue(Textbox1,stats)
End Sub[code].....
Essentially, I need to know what to put for noidea, and noidea2, like, byval or byref or what?

Before I build my own and after looking for quite a while (to no avai) does any one know of a function that will return the dates of a recurrence.
For instance:
- The recurrence might be the first Monday of each month.
- The second week of each month.
So what I want is to pass the recurrence information to the function and it will return in an array all the dates that are applicable.I've looked at some other topics here but none are as comprehensive as what I need.
