VS 2008 Associate A Timer To Function?
Mar 8, 2012
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.

I'm doing a school project in VB 2008 and I'm trying to get the buttons on the form to activate when you hit a given key. Like if I hit the "1" key, either on the numberpad or the keyboard, the "1" button would activate. I've tried the KeyDown method without sucess, but that might just be my code...The teacher suggested I use a txtbox instead of a lable for a display and then just disable all but number keys (which I can do, but that creates other problems with the input). I just want to be able to hit a given key, and have it correspond to a specific button. [And I can't use the ampersand hotkey thing... it underlines the txt in the button and makes it look ugly and it doesn't work with special characters]

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.

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.

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
Imports System.Drawing.Image

I've been trying to get this part of my code to work but it hasn't done anything. I'm trying to create a function that sends an email everyday at a specific time. I thought threading.timer would work but i haven't figured it out yet. I don't get errors when its executed but it also does nothing. If someone could tell me whats going on with this piece of code,

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

Net_mang_Form.Prg_bar.Visible = True
Net_mang_Form.Prg_bar.Value = 0
Net_mang_Form.prg_Timer.Start()
[Code].....
Here Net_mang_Form is Form1 and this code is written in button click event of Form2.
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.

Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?

I finally figured out exactly what I do not understand in vb.net. What I am needing to know is how to associate one object to another such as how would I associate text box(A) with text box( so that text box ( gives me the correct output after I type input into text box (A).

I am making a program with tabs, and in each tab is a textbox for editing a file (like how VB's designer does). How can I match up a textbox with a tab so that the cut, copy, paste, select all, etc. in the menu can tell what textbox to preform actions on? I was thinking of getting the current selected tab, and somehow finding the textbox associated with that tab.

I am trying to find a way to associate a key with an index for a Listviewitem in VB.Net. I'm not even sure if it can be done with .Net but I know in VB6 I could do a
Listview.listitem.add "somestring", "somestring".
For the application I am using this in, I cannot have duplicate item.text so I would make the key the same as the string. this also made accessing the item easier since I didn't have to rely on index to update the subitems.

I have gotten my application to open with an associated file type, but now I'm trying to figure out how to associate the file types to the app. I associated them on my PC manually by right clicking on a file and selecting "Open With.." and check-marking "Always use this application to open this file type".What I want to do, is have my program make itself the default application for a file type with the press of a button.If it makes it easier, I'm writing a text editor and want to give the users the option of making it the default text editor for .txt &/or .rtf files.

In my VS-2008 (VB.Net) application, I am using a background worker to make my main form more responsive. In case of any error (in DoWork event) I m displaying the error on another form. In this case main form cant be a parent of error form so if main form is clicked, error form go in the background (behind main form). I want to restrict the user to interact with the main form while error form is appearing. Is there any way to associate these two forms such that error form always appear in front of main form.
