IDE :: How To Make Stopwatch With Elapsed Times
Oct 2, 2009
I have VS 2008 and wow is it different from the old VB I used about 10 yrs ago! What I am trying to learn is how to create an ap that has a window that displays elapsed time like a stopwatch. Then I would like to be able to click a button to pause that time and start another timer, and then have yet another button to reset all. I have the form designed using a RichTextBox but am not sure that is the best way to display the times.

Bit stuck on this one, have seen alot about how to do it just cant seem to get it right. I want to have 2 text boxes with times in them.. at the moment i have them on click events then it just runs a Now for the time and fills the boxes from the system time. But then i want the 3rd box to find the elapsed time from the 2 times in the previous boxes but i just cant seem to figure it out

I'm using 2 System.Timers, which spawns a worker process during its elapsed event. If 1 of the events is busy doing something, the other thread elapsed event doesnt fire until the 1st thread has completed.Is there any way I can make both threads continuously fire its elapsed event??

So a timer's maximum interval is 1 which is a thousand ticks a second. A Stopwatch's frequency is 2238906 ticks a second on my pc...
I am wondering if there is a reliable way to trigger an event for each tick of the stopwatch without missing any ticks...
If I can somehow get a Tick event for the stopwatch, I believe I can increase the resolution of my input recorder....

A few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?

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 would like to know how to make a button click only so many times until it becomes disabled.
I would also like to know how to keep what is put in a RichTextBox there, without erasing the other text;
Example: Two buttons, the first puts "1" into the RTB, and the second puts "2" into the RTB. However when I press the second button, it over writes the first value.
How can I prevent this?
You Can Ignore this question below;
Old Question: I am working on a counter, and want to know how to make a button show itself if I hid it.
I have:
CODE:
And would like to know how to make one of the buttons visible again, with one big button.
I know it has something to do with an "If" statement.
Answer: Button#.Show()

I'm trying to make a form that takes user input 3 times, and each time compares it to the correct Answer... which is an array of {"C", "D", "A"}.Each time the user's input matches the correct answer ("strCorrectAnswer()"), then I'll add 1 point to intUserScoreCounter. I'm wondering why this code is returning an error (hilighted in blue)? Can I not compare a String to an Array?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEnterAnswers.Click
'Handles Enter Answers functionality
Dim strCorrectAnswer() As String = {"C", "D", "A"}

I am trying to make a timer that beeps 3-5 times and runs a progress bar. All it has to do is click start (timer set for 2 minutes starts) and as time runs out the progress bar fills. When the time is up 3-5 beeps happen. I am missing the coding for the 3-5 beeps and design parts for it and all coding for that along with code for setting the 2 minute timing. There is no label for telling the time left or to go just a progress bar. Here is my code so far.

I need to know to limit the number of times a radio button can be used. Maybe the number of times the radio button has been used can be stored in an XML file, and when the user wants to reset the counter all they would have to do it delete this file. I really don't know, that's why I'm asking you. But,the program will append a string every time a button is clicked with a radio button selected, I just need to know how to, for instance only allow RadioButton2 to be used in this manner say... 15 times.

I have just started using vb.net and I have a checked list box with times throughout the day shown as
00:00 - 00:14
00:15 - 00:29
00:30 - 00:44
00:45 - 00:59
What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?

I am trying to calculate a total cost from an elapsed time. Dependant on how long the time is, this will calculate the total cost. It has to be 3 to every hour. The elapsed time is displayed in label6 in "hh:MM:ss" format and the total cost needs to be displayed in label8.

I have one text box that contains a value for the "Start Time" and another text box that contains a value for the "End Time."Both of the values are expressed in a format for military time (i.e. 1200, 1300, 1430, etc.).When the "End Time" text box loses focus, I would like the "Elasped Time" (expressed in minutes) to appear in a third text box.Seems easy enough...right?Well the problem I'm having is since the first two numbers in military time are base 24 and the last two numbers are base 60, a standard calculation subtracting the "End Time" from the "Start Time" does not yield an accurate result.

Im using the express edition of VB.Net to do my project. I have several threads in my program which run fine. However, im stuck at this problem. I have a button in my form, which if I click I will call ThreadA (works fine), If i keep it pressed for more than 2 sec i need to call ThreadB (doesnt work), and if the time is more than 2 min, i need to stop and send a msg to the user. I have tried the timer to calculate the elapsed time, so the tick function would call the thread. BUT this doesnt work... Im not sure what do to.

display a Decimal (or double) to elapsed time [h]:mm:ss (hours:minutes:seconds)using vb.net?
example:
if you were to type "1.34666666666667" into a cell in Excel then choose Custom Format [h]:mm:ss The result is an elapsed time of "32:19:12". Using the OADate function only runs on a 24 hour clock so this does not work for longer durations unfortunately...
