In my app I want to retrieve data from database and add it to an excelsheet.
The Database's data are in string and BLOB format. I have retrieve the data and added to excel sheet using the frameworks:
https://github.com/andreac/RSSheet
The problem is that I want to add image to the worksheet too.
If any one has any idea about this please help me.
The RSSheet library does not currently support adding graphics to the sheet. You'll need to do this on the server side unless you expand the RSCell class to support this.
Depending on your backend this can be done easily. In PHP I used the PHPExcel library.

I am new to flutter and I found load csv from local and display as listview but I want to load from url and display. How can I do that?
A .csv from a remote source will probably have the content type of text/csv.
You should be able to call the url using a library (https://pub.dev/packages/http is a good choice, although I hear good things about Dio and probably a few others I haven't come across), get the data (e.g. as a http.Response), parse the response into some sort of model and then display it within the list view. Ideally the differences between displaying data from a local and remote source would be minimal - just where the data is coming from. This means you should be able to reuse the code you've written to load the data from a local source.
Without more information its hard to help. There's a good tutorial on building out Flutter apps using the Clean architecture at https://resocoder.com/category/tutorials/flutter/tdd-clean-architecture/. The difference will be that the Response data will be csv rather than JSON, so you'll need to sub in what you've done for the local loading.
We have some custom requirement to export our data into excel with custom and conditional cell styling. We have explored two libraries (xlsxjs and syncfusion) and would like to know whether it is compatible with salesforce Lightning Web Components.
Please suggest if there is any other way to achieve the same without the mentioned libraries.
PFA sample of expected excel file on export.
Greetings from Syncfusion.
It is possible to create Excel document using Syncfusion XlsIO similar to the shared screenshot.
But you have mentioned that you are exporting data to Excel, and we request you to share the below details.
Platform you are using
Control you are using to export data to Excel.
It would be helpful for us if you could share these details, so that we will check the compatibility from our side.
You can also mail the requested details to support#syncfusion.com
I work for Syncfusion.

I am new in Zend Framework and learning it. I want to upload image into my database and display that image in view page. I search lots of tutorial but no step by step guidance. Want a help. Thanks in advance.
You need to take a look on Zend_Form_Element_File in Zend documentation:
The File form element provides a mechanism for supplying file upload
fields to your form. It utilizes Zend_File_Transfer internally to
provide this functionality, and the FormFile view helper as also the
File decorator to display the form element. By default, it uses the
Http transfer adapter, which introspects the $_FILES array and allows
you to attach validators and filters. Validators and filters attached
to the form element are in turn attached to the transfer adapter.
Database side, you need to use a BLOB type to hold your image (I assume you're using MySQL).
However, note that best practices are to store the image path in the database instead of the image itself.
At last, there are tons of tutorials out there that explains precisely how to do what you're looking for, you just need to look for "file upload using zend element file" and you will find them!
I want to store textfield values in pdf file i.e I need to export form values to pdf file just for back up purpose as I cant completely rely on app database so how can I achieve this. Can somebody help me pls. Or can we export data in excel file.
I cant completely rely on app database
Millions of apps rely on Databases! what about XML storage?
XML will be easy to store, easy to retrieve values.
I believe you're looking for xlslib
Good Luck.
I'm using an NSXMLParser to read data out of a XML, but how can I make my iPhone App storing data into this specific XML.
The case is that I want to create an app to display available dates and one that administrates this dates, whether they are available or not (I'm using an UISwitch to handle this).
Thanks for your answers,
btype.
If you have small amount of data, you can save them in a plist.
See Property List Programming Guide
There's a github project that let's you create XML DOM objects. You can save your XML to your documents folder on the phone.
