How to looping with Timer?

1 New Member
Dear all,
I am a student making a MS Form application in C++. I would ask a question about "Timer". Sample code which I am developing is below.

private: System::Void buttonStart_Cli ck(System::Obje ct^ sender, System::EventAr gs^ e){
for (int i=1; i<=10; i++){
String^ strValue;
FunctionName(&s trValue);
int interval=1000; // time interval of looping equal to 1s
SetTimer(timer1 , interval, NULL);
do {
this->textBox->Text = strValue;
}
while(TimerFlag = 0);
TimerFlag = 0;
}

private: System::Void FunctionName(St ring^ *strValue){
*strValue = "Something which could change in each time of above looping";
}

private: System::Void OnTimer(int timerId){
if(timerId = 1){
TimerFlag = 1;
HWND hwnd = NULL;
KillTimer(timer 1);
}
}
...

Compiling errors are
1. SetTimer doesn't take 3 arguments
2. Kill timer doesn't take 1 arguments

How should I input the arguments and how should I correctly looping with 1s interruption? Please help me!

Thank you very much in advance.

If you are free to use any libraries then try to use ACE.
It has a timer also in it...

  1. while(TimerFlag = 0);
This will always fail to execute as

Expand|Select|Wrap|Line Numbers
  1. TimerFlag = 0
will always be false.

  1. if(timerId = 1)
This line isuseless unless you actually want to assing 1 to timerId, but the braces and the if are not neccessary.

I think you stick with the basics for now.

You need to get with your instructor and let him or her know you need some one on one time with a tutor.

Somethings are quicker when your not strugling with the slow communication of the internet.

Also, a tutor can see whether this code took you a few seconds to write or a few days, and they can imediately address the areas that you should be focusing on.

  1. if( SomeValue == 1) 
Notice the second '='?

I have a puzzling form timer problem that I didn't experience prior to Access 2003 (though I'm not sure access 2003 is to blame). Here's the situation: a computer has two access 2003 databases on it, a frontend and a backend. Case 1: If vba code on the frontend updates many rows (360,000) on the backend, a form's timer event (from the frontend) will stop firing until the user gives the form focus. (Note that the update itself always...

I did a test once using a looping variable, first dimmed as Integer, then as Long. I found the Integer was quicker at looping. I knew this to be true back in the 16 bit days where the CPU's (80286) word size was 16 bits same as an integer. Now with a 32 bit CPU I would have expected the long to be faster as it's the same size as the CPU's word size so wouldn't need sawing in half like a magician's assistant to calculate on like an...

I have created an array of timers (1-n). At first I just created windows form timers but I read that system timers are better for background work. The timers will just be monitoring different directories and updating a database. No interaction with the GUI. Problem is that the system timers do not have a tag property so I can tie in an object. example (old way):

Is looping FindWindow() ok? We have a simple little c# 2.0 app that’s sole purpose is to look for a dialog box from another app to pop up and then click it’s OK button. To do this we use a form with a timer control and some unmanaged code. The app works perfectly in test but I’m concerned about long term problems/leaks caused by frequent FindWindow calls (10 per second)? Although the popups might only occur 50-100 times a day,...

I have a Timer that I set to go off once a day, but it frequently fails! In order to debug I would like to be able to check, at any moment, whether the Timer is enabled and when it will next Elapse. Is there any way -- whether in my code, or in the O/S -- to determine when a Timer is scheduled to Elapse?

Note that although this involves SAPI, it is more a question about Timers and event handlers. I wrote a Speech Recognize handler (SAPI), and put some code in it to enable a Timer. It would not do it. If I bring this same code outside this event handler, it works just fine. Is this normal?

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
