Customize a Timer like control

An important property interval, this value sets how often each action is executed, the unit is milliseconds, and an important event is the timer, double-click the timer control to automatically generate the framework of this event, and write the ** action to be executed every interval milliseconds in this framework.

For example:1Put a timer control on the form.

2.Set the interval property of the timer control to 60,000 (representing 60,000 milliseconds, i.e., one minute).

3.Double-click the timer control and write **:msgbox( at the cursor"hello")

This way, a message box pops up every minute showing hello as an example, which is not really meaningful, but clearly indicates the use of the timer control.

Added the timer space, double-click to write what you want the timer control to do, and then add it to the page where you want to trigger the timer control; That's it.

First design enabled in the design window to be true interval is the frequency at which the event is fired.

Write the event you want to repeat in the timer1 tick.

First set the enabled=false of the timer, then set the enabled=true of the timer in the event where the Start button is clicked, and then write the **if >= 0 then of the mobile label in the timer event of the timer

Modify 80 to change the speed of movement.

elseend if

Then set the timer to enabled=false in the event where the "Stop" button is clicked

timer control.

The timer control mainly uses two properties, one is enabled and interval

enabled mainly controls whether the current timer control is available; Not available.

Available; The main thing is to set the time of the timer2 tick event, in millisecondsExample 1: to 9:00 prompt to go to the toilet: (

Handful; 1 minute.

private void timer2_tick(object sender, e)

Example 2: Every 2 hours, the user is reminded that he has been looking at the computer for a long time and needs to take a break; 7200 seconds.

private void timer2_tick(object sender, e)}

private sub command1_click() 'start=true

end sub

private sub command2_click() 'Stop=false

end sub

private sub form_load()= "Welcome to Visual Basic" true

falseend sub

private sub timer1_timer()iif( <= - 100)end sub

Dude, what do you want to achieve? Didn't get it. Do you want to stage a value?

Do you put both label and timer in custom controls, or just label in custom controls?

It can't be written in the button event, you need to double-click the time control to write it in time space, please see for details.

Is the enable property of the timer set to true?

How much is set?,And that's.,Can your ** run?,I look like C and like VB.,And the syntax is not right.。

will be done. But there is a caveat:

It is single-threaded, it only runs in the UI thread, the timing accuracy is about 55ms, and the next event will not be triggered when the current event is not processed; Processing for too long will cause the interface to freeze.

It is multi-threaded, and the triggered event runs in the thread in the threadpool, so when the current event is not processed, a new thread will be opened to process it.

You'll need to use new thread, multi-threading, but cross-threading is more cumbersome, and it's better to use something else.

For example, turn off the timer first, execute the program, and open the timer when it is finished

I'll finish copying. The end effect may be that you delay by 5 seconds. Copy things for 10 seconds, delay them for another 5 seconds, and then do something else.

This means that your five-second interval will not start until after the first event has ended.

is a class. It can be used not only in form programs, but also in console programs and Windows services.

The general ** used is as follows:

timer = new ;

true;1000d;

true; new ;

void timer_elapsed(object sender, e)

Its practical method is the same as pressing a timer in the form, you can drag the timer control on the form to the form and then you can see the relevant ** in the file corresponding to the form.

After each time interval, the timer control will start a thread and execute the ** in the elapsed method.

The control interval you are talking about is 5s and it takes 10s to execute the statement, which won't be a problem because they are 2 threads. Unless you're using a common variable in both threads, or using the same io resource, that creates a problem.

timer1 tick is the method name, ontick="timer1_tick", refers to the ontick event that registers the timer1 tick method with the timer control.

To put it simply, the timer control executes the timer1 tick method every fixed period of time (determined by its property interval, in milliseconds), provided that the timer control is started.

Looks a bit like this :

private void timer1_tick(object sender, eventargs e)

You can see where ontick is used to see what it does! You have to give more ** to know!

Your **logic is wrong.,If the thread is paused, it will block the program from executing downward.,Maybe that's how you can't see it**display.**

You should change it to the following idea:

private void timer1_tick(object sender, eventargs e)

If the timer1 tick time is not used to show hidden, then you can add a timer's event to the timer1 tick to handle it, and it is best not to sleep the thread.
