QUESTION
I have a Excel file like this:
I wrote a code that allows me to extract all the photos from the xlsx file and insert them in a folder.
There are several merged cells in the file and before processing I would like to remove all the merged cells from the Excel file. I tried with $objPHPExcel->setActiveSheetIndex("0")->unmergeCells();
but it doesn't work.
How can I solve my problem?
...ANSWER
Answered 2020-Oct-09 at 08:57I have changed the library to PhpOffice\PhpSpreadsheet because PHPExcel is outdated.
QUESTION
I wrote a php script that allows me to read an uploaded excel file and insert all the images contained in a folder by renaming them with the cell values "style" and "color" to have style_color.jpg. The script works fine but if I upload an xlsx file containing merged cells like this:
images with the same "style" doesn't work.The tool will just put the style on the first image. I would like the first two images to be called :

Answered 2020-Oct-01 at 19:36If you can assume that you read the rows in sequence, you can get the cell value and if the cell is blank, use the previous value. This code use ?:
to say if it's blank, use $stylecode

QUESTION
I have an Excel file (xlsx) with several pictures
And I have this php script that allows me to extract the photos contained in it, insert them in a folder and rename them according to the name of the cells in front of each photo.
The script works but I would like to start reading the lines from line 5. I tried with $i <= 3
to skip the first 4 lines but this causes a shift in the picture names. How can I solve my problem?
ANSWER
Answered 2020-Sep-30 at 13:58I think getDrawingCollection()
gives you a list of all the drawings on the active sheet, but this list is not directly related to cell coordinates. So skipping some items of this list is not the same as skipping rows.
Not sure how this goes with the old PHPExcel libs, but with current PhpOffice\PhpSpreadsheet, a Drawing or BaseDrawing objects should have their $coordinates property.

QUESTION
This question could be asked in a few different ways but my end-goal is to encapsulate one file from a ZipArchive
(Rust zip crate) into a struct called ZipReader
that implements Read, like so:
ANSWER
Answered 2020-Aug-26 at 16:32As Coder-256 mentioned, owning_ref::OwningHandle
provides functionality to solve the borrowing problem, but not the lifetime problem. There is an open issue on the repo for owning_ref
that describes an equivalent situation and requests additional functionality to solve it, but it has been open since 2017 with no resolution.
I ended up modifying the zip crate to transfer ownership of the underlying stream instead of holding the reference to the ZipArchive. This is satisfactory enough for my purposes, but a solution like owning_ref
seems to be the correct approach for this type of problem.

QUESTION
I was developing a simple application on Qt 5.5. Since Qt 5.5 does not have QChart class features, I had to install and build my Qt 5.5 project on the 5.8 distribution. For my project I am using this 3rd party software called the QXlsx to create and edit Excel spreadsheets. This library was working flawlessly in Qt 5.5 but fails to compile on the Qt 5.8 version. The compilation returns the following error;
/Users/Vino/Documents/My Stuff/Qt Projects/Fundemental Analysis/FundementalAnalysis/3rdparty/qtxlsx/src/xlsx/xlsxzipreader.cpp:52: error: implicit instantiation of undefined template 'QVector' QList allFiles = m_reader->fileInfoList(); ^
I am not sure what it means, but I am quite confident that I don't have to make any changes on the source code of this library since it worked previously on Qt 5.5.
Anyway this is the source code where the error occurs
...ANSWER
Answered 2017-Feb-20 at 20:36So I fixed my problem; I was using the oldest version of the QXlsx, and according to this post, there were many new revisions on gitHub. Installing the new version solved the issue.
QUESTION
I am trying to catch errors from a group of goroutines using a channel, but the channel enters an infinite loop, starts consuming CPU.
...ANSWER
Answered 2017-Aug-20 at 20:061. For the first point, the infinite loop:
Citing from golang language spec:
A receive operation on a closed channel can always proceed immediately, yielding the element type's zero value after any previously sent values have been received.
