Resolve Some errors without stopping program running
Write a function like:
prtErr(const string prt) { switch(_LastError) //case 0: ERR_NO_ERROR { case 1:return; // nothing to alarm! case 2:return; // nothing to alarm! case 3:Alert("ERR_INVALID_TRADE_PARAMETERS: "+prt); ResetLastError(); return; ... } }
Now you can use it:
prtErr(StringConcatenate(__LINE__," var1: ",var1," var2: ",var2,...));
Hello again,
So take GetLastError() and store value?
Compare GetLastError() to new GetLastError().
if (statement)
do this
else
do this
{
errorlevel=(GetLastError());
swt();
}

Carl Schreiber:
why?
I am trying to debug code at the moment. I am not sure I am going to achieve any result.
why?
The code I posted to start with, I believe was posted somewhere in the forum. I was unable to find it, so I wrote it again as far as I was able to remember it.
Not all the code, but here:
Any really newble people out there "DON'T USE IT"

Carl Schreiber:
- Why don't you use the debugger?
- Why didn't check the logs?
- Buy = Ask (ok) Exist-Buy = Sell(!!)
- Are the stoploss ok: a) > 0; b) prices (not pips or points?)
My advice for you for 2018: Start learning how you can control yourself what you are doing!
I agree 100%
Learning is a 1000% effort, and you can get it wrong anyway.

Happy New Year to you Carl.

Hello everyone, I have started writing some switch statements to hopefully fix some possible problems with my code running. I admit most of which I doubt I will ever come across, or in fact need to use.
Now if more than one error occurs, where the solution to the first causes errors with others. A decision about which error is most important and simply ResetLastError() and wait for the error to occur again?
