Wow good info thanks, i will look into that. About multithreading how would i go about making use of multiple processors?
February 2nd, 2013, 03:27 AM
Fair point, although i am very glad i made the change. As the vba code takes over 2 weeks to run, and C++ takes 3 hours. I would say that is a massive improvement

Getting all info now ( i stupidly had the csv open when running the programme), and is still running at just under 6 mins. Although now i have unchecked the 1st for loop, it will take around 180mins...

I think it was me (user error), maybe i hadnt compiled before one of changes. But getting all info that was requested on the export now: Still getting those warnings though

I am having one slight problem, with the headerarray[q] & c
Getting this warning,

Yep, struts definitely confuse me.
Working wonderfully thank you very much for your time and effort

Would these two lines be right?
February 1st, 2013, 08:26 AM
Just as a point of interest. All those for loops iterate 36889042944 times.

I have ran the debugger, it is something to do with the stack. I get this error:
#0 76F315DE ntdll!LdrQueryProcessModuleInformation() (C:\Windows\system32\ntdll.dll:??)

Approx it takes, 0.45 seconds to read and load the intial arrays. Ie dataarray, directionarray & headerarray.

Yep got it now..i had to click on the project.

You are absolutely right, very silly of me :) (and a little embarressed lol)
What is the best way to debug in code::blocks?
February 1st, 2013, 06:37 AM
Your previous code for export to csv file worked a treat, ty very much.
I am getting a few bizarre results though:
With this part of the code:
float t = ( y / z );

Excellent thankyou for the info, i will go through and see which is false more often. That should help a bit at least
January 31st, 2013, 01:35 PM
Thankyou 2kaud i will give that ago tomorrow, and get back to you with the results
Another thought i had while out running, with this part of the code:
if (dataarray[jRows +...
January 31st, 2013, 01:33 PM
Good point, for example if i could get the currently 6 mins down to say under 30 seconds i might be tempted to use more data that is available, and those 15's which are minutes, could become singles...

In the global compiler settings, these are the ones that seem to do with optimising. If that is what you mean?
-optimize generated code (for speed) [-O]
-optimize more (for speed) [-O1]...

int currentColumn = someValue;
for ( int i = 0; i < numTotalColumnsInArray; ++i )
if ( i == currentColumn )
if ( CompareMatrix(currentColumn, i) == whatever )
January 31st, 2013, 01:13 PM
I have very very few debugging options, most are greyed out. Those that are on in settings are:
- Autobuild project if it is not up to date
- When stopping, autoswitch to first frame with valid...

Here is the updated code:
January 31st, 2013, 07:37 AM
Sounds fair enough. With the q and c if you look at my little 3x3 matrix above. I compare column1(ie q) with the second and third column (ie c). I then compare column 2 (q) with the first and third...

Okay after lots of searching, got the -ANSI now. And as you said it doesnt like variable length for array
January 31st, 2013, 05:33 AM
Thats a lot to take in, thankyou for your time.
I am using Code::Blocks editor and on the compiler settings menu, it had automatically selected GNU GCC Compiler. Which compiler should i chose,...
January 31st, 2013, 04:00 AM
Many thanks for your help.
I have written some code now....and the reading in doesnt actually take long less than half a second. So all the time is going to be taken up with anaylising the arrays...
January 30th, 2013, 05:31 AM
I understand i need to learn C++ first
But not to worry i have been reading up about reading from csv file. And have written code that reads all the values from the csv file, still a long way to...
