We were using Excel but now started using Spreadsheet as it is the future.
Recently in our app, i have to make a change,
This is our excel file logic.
FROM
var $excel_start_row_index=1;
var $excel_start_column_index=0;
TO
var $excel_start_row_index=1;
var $excel_start_column_index=1;
Because we were not showing one column. Maybe I think it happened with our current composer update. So I see some other changes in how to style and applyFromArray has new style array for setting the background color. So is this change in the library to get start cell.
I see
namespace PhpOffice\PhpSpreadsheet\Worksheet;
/**
* Active cell. (Only one!).
*
* #var string
*/
private $activeCell = 'A1';
But where can I find the numerical representation of it? Like $activeColumn = 0 , $activeRow = 1. something like it.
What is the numerical equivalent of "A" here is it 0 or 1.
Here Github Issue See the second comment by Mark Baker he says it starts with 0 in PhpExcel. Is it same in PhpSpreadsheet?
After much discussion and debate, it was decided to start column indexing from 1 to try and be more consistent https://gitter.im/PHPOffice/PhpSpreadsheet?at=59fa9f27976e63937e17fd27

I'm a new user of PARI/GP, and after writing my script, I wanted to make a graph of it. As my function take an integer and return a number, it's closer to a sequence. Actually, I didn't know how to do it, so I read the documentation of PARI/GP, and after that I made some test in order to obtain a graph from a list.
After reading an answer in stackoverflow (Plotting multiple lists in Pari), I wanted to test with the following code:
plothraw([0..200], apply(i->cos(i*3*Pi/200), [0..200]), 0);
But when I do it, it tries to open something on latexit, but then it crash and give me a problem report.
I didn't even know that I had an app named latextit, maybe it was install during the installation of PARI/GP. Anyway, how can I fix this?
PARI/GP definitely doesn't install latexit.
The way hi-res graphics work on the Win32 version of PARI/GP is to write down an Enhanced Metafile (.EMF) in a temp directory and ask the system to
"open" it. When you installed latexit it probably created an association in the registry to let it open .EMF files
i3Pi does not mean what you think, it just creates a new variable with that name. You want i * 3 * Pi instead.
The following constructions both work in my setup
plothraw([0..200], apply(i->cos(i*3*Pi/200), [0..200]), 0);
plothraw([0..200], apply(i->cos(i*3*Pi/200), [0..200]), 1);
(the second one being more readable because a red line is drawn between successive points; I have trouble seeing the few tiny blue dots)
Instead of apply, you can use a direct constructor as in
vector(201, i, cos((i-1) * 3 * Pi / 200))
which of course can be computed more efficiently as
real( powers(exp(3*I*Pi/200), 200) )
(of course, it doesn't matter here, but compare both commands at precision \p10000 or so ...)
Pls help me
A few weeks ago it came out of gamemaker 2.3, practically in the gamemaker language they changed the scripts into functions, but now after converting the files to be able to reopen them, I double-checked all the scripts and etc but anyway when I start it it remains a black screen, however it doesn't give me any compilation errors or whatever, what could be the problem?
Ps.
I might sound stupid, but if someone has the same program as me I can pass the project to them so they can see the scripts for themselves, so basically it's just the base and there is only the script to make the player walk and for collisions, I know that no one would want to waste time, but I ask the same
Its possible that your code is stuck in an infinite loop, here's an example of what that might look like:
var doloop = true
while(doloop == true){
x += 1
y += 1
}
the "doloop" variable is never changed within the while loop, so it is always equal to true and the loop never ends. Because the code never finishes looping, it can never get around to drawing anything, so you end up with a black screen. The easiest way to check for these is to put a breakpoint/debugging point at the beginning and just after every while/for/do/ect loop and debug it. e.g. (I am using asterisks "*" to represent breakpoints)
var doloop = true
* while(doloop == true){
x += 1
y += 1
}
*
When you get to one of the loops remove the first breakpoint and hit the "continue" button in the debugger. If it (it being the computer) takes an longer than it should to hit the second breakpoint (as in, you wait for a ten seconds to or two minutes (depends on how complex the code is) and it still hasn't hit the second breakpoint), then you should replace the breakpoint at the beginning of the loop to check and make sure it is still in there. If it is still in the loop, then that is likely where the code is getting stuck. Review the loop and everywhere any associated variables are set/changed, and you should be able to find the problem (even if it takes a while).
Majestic_Monkey_ and the commentors are correct: use the debugger. It's easy and it's your friend. Just place a red circle on the very first line of code that runs, and click the little bug icon and you can step through your code easily.
But to address your specific issue (or if anyone in the future has this issue): scripts have changed into files that can have many functions. Where you used to have
//script_name
var num = argument0 + argument1;
return num;
You would now have
function script_name(a, b) {
var num = a + b;
return num;
}
All you have to do is create a decleration for your new function:
function my_function_name(argument_names, etc...)
Then wrap all your old code in { }, and replace all those ugly "argument0" things with actual names. It's that easy. Plus you can have more than one function per script!
How can I increase maxTokensPerLine in my own Atom.IO environment?
I've got some long lines causing syntax to not be recognized properly, for example not highlighted correctly and brackets not taken note of etc.
But this seems to be a current source containing it. It seems to be taken as a parameter which suggests it could be configurable?
grammar-registry.coffee
I found
this.maxTokensPerLine = (_ref1 = options.maxTokensPerLine) != null ? _ref1 : Infinity;
on line 22 of /usr/share/atom/resources/app/apm/node_modules/first-mate/lib/grammar-registry.js
maxTokensPerLine also appears in
/usr/share/atom/resources/app/apm/node_modules/first-mate/lib/grammar.js
I tried adding maxTokensPerLine: 1000 in config.cson under *, core and editor, but it had no effect.
(old) maxTokensPerLine
syntax.coffee
You can use the package grammar-token-limit, which will handle changing it for you. All you need to do is specify which value you want in the package settings.
I guess if you want to do it yourself, this package would be the place to start looking.
The digital clock in KDE Plasma 5.4.0 does not allow you to specify a custom format. I'm attempted to hack the plasmoid, which is just a QML file. However, I've been unsuccessful. There is a conditional branch, which allows you select from one of the following strings.
return Qt.SystemLocaleLongDate;
return Qt.ISODate;
return Qt.SystemLocaleShortDate;
I attempted to modify it to the following, but it's not working. Presumably I just have the syntax wrong.
return QDate::currentDate().toString("dd.MM.yyyy");
How can I modify the plasmoid to show a custom date format?
EDIT
I suspect that I might be changing the wrong line. The source code for the plasmoid I'm trying to hack is here. After decompressing the file, it's specifically at applets/digital-clock/package/. (When installed, this directory is moved to /usr/share/plasma/plasmoids/org.kde.plasma.digitalclock/.) I attempted changing line 43 of contents/ui/DigitalClock.qml.
I attempted changing the line to return "foo";, but this had no effect. Again, I'm not sure if I have the syntax correct.
As stated in the comments, the line returning this value isn't a reference to the date itself, but merely specifies the format. I'm unsure of the syntax to hack the code here, but instead, you can change the code that references this property later.

I'm having this problem when I tried to extract information from excel files. Here's my situation, I have 34 Excel files which I received from my various users.
I'm using PHP version 5 to extract from the Excel files. My script will loop for every files, and looping again according to sheet name, and lastly looping again according to cell addresses.
The problem arised when the users had entered into a cell for e.g. =+A1 which means the users referencing the cell value to another cell due to it has the same value with cell A1.
When I checked in mysql (as I saved those for future use) I found from the record for a particular cell is identical with another record obtained from the same cell but in different excel file. What I meant is that, as my php script will loop from one file to another file, the first time PHPExcel read for e.g cell C3 which has some value USD3,000.00 the next files the PHPExcel may go to the same cell C3 but this time the C3 cell contain a formula that referencing to cell A1 ("=+A1" formula)which has value USD5,000.00.
PHP script suppose to record in mysql for USD5,000.00 but it didn't. I suspect that the PHPExcel script did not clear the variable at first round. I've tried unset($objPHPExcel) and destroy the variable but it still happening.
My coding is simple as follows:
if(file_exists($inputFileName))
{
$inputFileType = PHPExcel_IOFactory::identify($inputFileName);
$objReader = PHPExcel_IOFactory::createReader($inputFileType);
$objReader->setReadDataOnly(true);
$objPHPExcel = $objReader->load($inputFileName);
//to obtain date from FILE and store in DB for future comparison
$validating_date_reporting = $objPHPExcel->getSheet(0)->getCell('C10')->getValue();
$validating_date_reporting = PHPExcel_Style_NumberFormat::toFormattedString($validating_date_reporting,"YYYY-MMM-DD");
$validating_date_reporting = date('Y-m-d',strtotime($validating_date_reporting));
//first entry
$entry = mysql_query('INSERT INTO `'.$table.'`(`broker_code`, `date`, `date_from_submission`) VALUES("'.$broker_code.'","'.$reporting_date.'","'.$reporting_date.'")') or die(mysql_error());
foreach($cells_array as $caRef=>$sName)
{
foreach($sName as $sNameRef=>$cells)
{
$wksht_page = array_search($caRef, $sheetNameArray);
$cell_column = $wksht_page.'_'.$cells;
echo $inputFileName.' '.$caRef.' '.$cell_column.'<br>';
$value = $objPHPExcel->setActiveSheetIndexByName($caRef)->getCell($cells)->getCalculatedValue();
echo $value.'<br>';
if($value)
{
$isdPortal->LoginDB($db_periodic_submission);
$record = mysql_query('UPDATE `'.$table.'` SET `'.$cell_column.'` = "'.$value.'" WHERE broker_code = "'.$broker_code.'" AND date_from_submission = "'.$validating_date_reporting.'"') or die(mysql_error());
}
}
}
}
I really hope that you can help me out here..
thank you in advance.
PHPExcel holds a calculation cache as well, and this is not cleared when you unset a workbook: it has to be cleared manually using:
PHPExcel_Calculation::flushInstance();
or
PHPExcel_Calculation::getInstance()->clearCalculationCache();
You can also disable calculation caching completely (although this may slow things down if you have a lot of formulae that reference cells containing other formulae) using:
PHPExcel_Calculation::getInstance()->setCalculationCacheEnabled(FALSE);
before you start processing your files
This is because currently PHPExcel uses a singleton for the calculation engine. It is in the roadmap to switch to using a multiton pattern later this year, which will effectively maintain a separate cache for each workbook, alleviating this problem.
EDIT
Note that simply unsetting $objPHPExcel does not work. You need to detach the worksheets before unsetting $objPHPExcel.
$objPHPExcel->disconnectWorksheets();
unset($objPHPExcel);
as described in section 4.3 of the Developer Documentation. And this is the point where you should also add the PHPExcel_Calculation::flushInstance();
