Hello Everyone,
If i have an event that happens always,

C#

Application.Idle += Myevent;

and if there is a variable that changes every time in this event,

C#

Myevent()
{
   var = value;
}

How can i capture old value and new value of this variable and then compare between,

Thanks in advance,
z3ngew

Use a session variable to capture the first one and compare that to the second one after taking it back out of session.

What is var and where does value come from?

Not clear. The code you show will not compile, anyway...

This is not my code, this is an emulation of it

Please be so nice and take the time and make it a somehow working version - or do you expect us to spend that time for you?

The quality of the question is too low and you seem to be ignorant on requests to improve. My 1.

Sorry, no. "Emulation" means something totally different. Not a valid question, honestly.

Hi,

Try this:

C#

int oldVar = aVar; // I use int in this example
                   // I also use aVar instead of var, because var is a keyword
int newVar = value;
// compare

aVariable = newVar;

Hope this helps.
