Converting Frames-per-second To Timer Interval?
Mar 16, 2010
I have an animation program which allows users to import and animate images. I do this using timer events. I have a listbox which contains the image references, and a Image which displays the chosen image. Here is the
When the user clicks the "Animate" button:
vb.net
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles animate.Click
Dim cananimate As Boolean = True
[Code].....
I want to make a dialog to appear and allow the user to select a custom FPS for the animation. For instance, if they type 15, the listbox must go down 15 images in 1 second. But how do I convert FPS to a timer interval?

I am writing an industrial control front-end that has some "fancy" graphics to indicate the states of some machinery. For example, I indicate that some heaters are on by showing red wavy arrows emanating out from a picture of a heater. I accomplished this by creating a class that inherits from PictureBox and using a timer to advance the images:
Public Class AnimatedPictureBox
Inherits PictureBox
Private WithEvents Timer As New Timers.Timer
Public Property Interval As Double
[Code] .....
My question is "Is this an alright way to go about this or is there some obvious better way?" I'm not too good at programming and am worried that having several of these objects with their embedded timers taxing the CPU. I went with animated GIFs for some other animation stuff, but here, I wanted to be able to handle image formats that can handle a larger palette than a GIF (if that makes sense). In other words, when I tried to save some of my animations as GIFs, the image quality took an unacceptable hit.

So, I have two timers. 1 Timer is set with an interval of 1000 (milliseconds), therefore it goes off every 1 second. For some reason, when I set the interval on the same timer to 1, it goes off 100 times every second. Shouldn't it go off 1000 times every second? What's going on?

How can I get a timer to run one interval,one interval only, and stop? Until now I have only used timers to keep running until I say to stop. Also I need a timer that will start at the beginning of, and run until any given process is completed.Upon completion it should shut off and tell me how long the process took. Kinda like a stop watch with a Stop / Start "Trigger".

I was wondering how do I make it so that people that use my program can change the Timer Interval. So they can set the timer.

How would you make the Interval of a timer to be between two times.
E.g if you wanted an event to occur between every 7 and 20 seconds?

I am trying to write a simple code that will essentially change the background oclor of a form from say red to green, like every five seconds.(Actually, it will be green 4 and red 6 seconds). I set my timer interval to 1000 and enabled it. So when I write my if/then statements in the timer area, would I be using timer.interval <=4, or timer.interval <=4000 to count off four seconds?

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:

I have dragged and droped a timer control "tmrGetMappingXML" from the Common Controls Tab in Tool Box. The issue that I am mentioning also appears for the Timer Control present in the Components Tab in tool box.
In the form Load I have written:
HTML
tmrGetMappingXML.Interval = 3600 '1 Hour = 3600 Seconds
tmrGetMappingXML.Enabled = True
tmrGetMappingXML.Start()
The timer interval is also set in the design time to 3600 seconds. But the Tick event of the timer fires continuously every second.

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)?

my event in timer goes too fast, i need to slower it. the interval is ok, i cant use sleep because it freeze everything ( webbrowser control ) and it need to stay active not freezing. i tried application. doevents() no result same problem, is there a way to do what i need? its a program that automatically fill a webbrowser form and restart every-time. there no logout button so i need to use setmouseposition and mouse_event but timer do event too fast one after other and if i use sleep everything go wrong.

I'm working on a small game that I want to sync with the intensity of the music. I have a timer added and I want the interval to change with the intensity of the song playing. How would I go about doing this? I tried playing with Zplay and BASS.net with no luck.

my function is to adjust a timer interval according to a integer variable.
Original code (works fine):
Code:
Dim UpdateSnakeSpeed
Select Case UpdateSnakeSpeed
Case currentscore > 199
[Code]....
This is the code I'm using right now. (works fine and is more logically correct than the above case statement. I have chosen to go with if .. end if statements over case, as I do not have a full understanding of what the variable SnakeUpdatespeed is doing in the Select case statement. If someone explains then I'll consider it. Also I know case statments are only meant to be used for 1 option selections, however I'm amazed that it still works in case. Atm it's going to be if end if. Now I'm trying to get the for next loop going with this (if it's logically possible). that's what i'm aiming overall out of this thread. To make a convenient loop.

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.

I have an application that updates a great number of fields on a pretty short interval timer. (on a standard form)Question is as follows... which one of these statements will work better for this? (working better = faster/smoother)Dim textToUpdate as string
if textbox1.text <> textToUpdate then textbox1.text = textToUpdate
OR textbox1.text = textToUpdate

I dabbled in VB several years back, but recently I have had the need to actually use it for something purposeful. I'm by no means fluent in programming. I am trying to create a countdown timer using the system clock. I have set it up so that upon pressing a button, a countdown is displayed in a label decreasing from a number that the user types into a text box.

I am trying to make a program in visual basic 2010 where the user enters hours minutes and seconds into text boxes and then the program will count down from that until its equal to 0 when a msgbox appears and says its finished. I was converting hour entered, minutes entered, and seconds entered all into seconds and then having a timer subtract 1 from that until its equal to 0. But the problem I'm having is that I want to display the hours, minutes and seconds left in a label to the user in a format of: "hours: 0 minutes: 23 seconds :42" but how to display it in this format.

I have a screencasting program where it takes 10 screenshots every second and saves it to a temporary directory then through ffmpeg the series of images are compiled into a video format. My problem is that due to the computers processing power or the size of each screenshot and its quality it sometimes takes longer than 100 Milliseconds to create one causing the whole video to be off balance. How can I ensure 100% that 10 Images will be stored?

I am using frames for my web application.Description
(1)Left Frame with a list of buttons (clicking them opens a web page in the right frame)
(2)Right Frame, opens the web page passed by the left frame.
Problem: Button click works perfectly in Internet Explorer 8.0 on production machine, Windows XP, 32 bit.Button click event doesn't open anything in the right frame, just remains as it is, in Firefox, Chrome, Internet Explorer 9.0
Intial code that loads the frames

I've been racking my brain trying to figure this out. I've done a ton of searching but I can't find what I'm looking for. Right now my program gets a image file, converts the image to 4 colors (Black, Red, Yellow and Green), then converts each pixel to a number for that color.This works great, but now I'm trying to do this for an animated image, but I need to be able to loop through each frame, but I haven't been able to figure out how to access each frame of the image.
