I use Aspose.Cells for java to convert excel documents to html. But there is problem with umlauts.
there is the code I use to save excel documents to html
com.aspose.cells.Workbook workbook = new com.aspose.cells.Workbook(stream);
workbook.save(path, com.aspose.cells.SaveFormat.HTML);
is there some way to resolve this?
This type of issues might occur due to missing fonts. Since Aspose.Cells needs the underlying fonts (used in the workbook) to be installed on the system for rendering to PDF, HTML or image, so you got to make sure all the underlying fonts are there on the pc and your application should access to that folder. You can also find the needed fonts for your workbook using Workbook.getFonts() method. You may put all the font files (.ttf files) in some folder and set the fonts directory at the start before using your original code.
e.g
Sample code:
......
String MyFontDir = "your_fonts_folder_path";
// Setting the fonts folder with setFontFolder method
FontConfigs.setFontFolder(MyFontDir, true);
//.......
//Your code goes here.
//......

I've tried loading a local html file using webkit_web_view_load_uri() with a file:// URL. However, the webview would display a blank page. To circumvent this, I tried using webkit_web_view_load_html() and it worked correctly.
Now that I'm trying to load some images in the html using the <img> tag, the images aren't loaded (It displays a blank page).
I'm puzzled because I tried before (~ 2 months ago) a similar method and it worked.
Note: I copied the contents of the generated HTML into a file and loaded it with Firefox and it worked as it should (The images are visible), but with another WebKitGtk application I had lying around the images didn't load.
Note: I'm using C++ as the main programming language (I'd prefer having C++ types in the solutions only if possible)
Note: I have set webkit_settings_set_allow_file_access_from_file_urls() and webkit_settings_set_allow_universal_access_from_file_urls() to TRUE
Ok, I've managed to solve this. The solution had NOTHING to do with webkitgtk, which is strange. It seems that the application was trying to download the page instead of loading it. This traces to a faulty MIME type database.
Tl;Dr:
Execute this:
rm ~/.local/share/mime/packages/user-extension-html.xml
update-mime-database ~/.local/share/mime
and use webkit_web_view_load_uri() instead of webkit_web_view_load_html() with a file:// URI
I had the same problem in C. You have to explicitly set file:// as base_uri when you call webkit_web_view_load_html().

I'm looking into using a rich text editor in my Django project. TinyMCE looks like the obvious solution, however i see that the output format is html (here). Goal is to store user input and then serve it inside a word document using python-docx( which is not html).
Do you know of any solution for this? Either a feature of tinyMCE or a html to word-format converter which keeps styles, or maybe another rich text editor similar to tinymce?
UPDATE:
This is another option which i found to be working fine. Still at the point of trying to convert HTML to Word without losing styles. A solution for this may be pywin32 as stated here but it doesn't help me that much + it's Windows only.
Update2
After quite some digging i found pandoc and pypandoc which appear to be able to translate in any of these output formats:
"asciidoc, beamer, commonmark, context, docbook, docbook4, docbook5, docx, dokuwiki, dzslides, epub, epub2, epub3, fb2, gfm, haddock, html, html4, html5, icml, jats, json, latex, man, markdown, markdown_github, markdown_mmd, markdown_phpextra, markdown_strict, mediawiki, ms, muse, native, odt, opendocument, opml, org, plain, pptx, revealjs, rst, rtf, s5, slideous, slidy, tei, texinfo, textile, zimwiki"
I haven't figured out how to integrate such an input to python-docx.
I had the same challenge. You'll want to use Python's Beautiful Soup library to iterate through the content in your HTML editor (I use Summernote, but any HTML editor should work) then parse HTML tags into a usable format for python-docx. Pandoc and Pypandoc will convert files for you (e.g. you start with a LateX file and need to convert it to Word), but will not provide the tools to need to convert to and from xml/html.
Good luck!
I am using Workbook gem to preview the excel file without page breaks in my website. Right now, I am successful in extracting the excel file and writing it into html format and display as preview.
The following code extracts and writes the excel to html:
excel_file = Workbook::Book.open "#{file_url}"
excel_file.write_to_html(file_name + ".html")
But this gives me an unformatted html sheet with no rows and columns or any of the existing excel file.
According to murb/workbook documentation, it is said that we can pass the format as a hash within its options.
write_to_html(filename = "#{title}.html", options = {})
So, to achieve the format hash, I tried the following code:
excel_file.template.formats
But this returns a null hash. So, how can i get all the formats from the excel file and write to html? Or at least show the html table with borders for all rows and columns.
The author here. The Workbook gem is mainly built to extract and rerepresent the data in files, and not so much the formatting. In the past I made a few attempts on adding support to maintain formatting when converting, but it is far from complete. Some importers don't even set the formatting hash as you found out, notably the xlsx importer needs work on this.
The HTML was built to simply give a basic preview of the data. It basically returns a html-page with all tables which is by default unformatted, although format-names are used in the classes. There is an option though, if you'd pass style_with_inline_css: true... but then it requires an importer to actually set the format hash properly...
I'm happy to guide you here and there when you want to improve the xlsx importer code to suit your needs and hopefully the workbook gem in general, but it will need serious work if you want more than just some background colours and font properties.
Here is my requirement.
I am giving one text box, users have to type the folder path.
To help the users, when they write the first folder structure say "C:\" into text box,I want to display all the folders available in that path (same way how we get all the directory structure when we use "windows run"). Any code snippet in c++ will be of great help.
Thanks in advance.

The autocomplete feature is built into the shell and available to clients (see Using Autocomplete). Autocomplete can be used with any standard Edit Control. To enable autocomplete just call SHAutoComplete:
bool EnableAutoComplete(HWND hWndEdit) {
if (SUCCEEDED(::SHAutoComplete(hWndEdit, SHACF_FILESYS_DIRS)))
return true;
return false;
}
SHAutoComplete allows for a large number of flags to customize the autocomplete behavior. In case none of the options match your requirements, you can implement your custom autocomplete source, and get full control over the suggestions (see How to Enable Autocomplete Manually).
I am trying to get the icon of an app (doesn't matter which one). I noticed Qt doesn't have something like GDesktopAppInfo and therefore I tried getting it through QSettings from /usr/share/applications/appname.desktop. That's already a problem, because the desktop file might not be there. Anyway, going further to extract the Icon key. Now I dunno how to find the url (notice that I need the url, sure I could make a QIcon, but I need to export it to QML, which would mean another QQuickImageProvider class, anyway, I don't wanna go that way). Is it possible, or is the aforementioned QQuickImageProvider my only solution?
Here is a little guide that might help you find your way. Keep one thing in mind: start with the basic case, get code running and extend it to more difficult cases later.
For now, lets assume the following:
.desktop file is in /usr/share/applications
App icon is in SVG or PNG format
App icon path is absolute
App name is lower case and does not contain whitespace
Input: App name "git-cola"
Read /usr/share/applications/git-cola.desktop
Use a QRegularExpression to get the Icon value
You get an absolute iconPath, e.g. /usr/share/git-cola/icons/git.svg
Have an invokable C++ function that exposes a QUrl to QML
In QML, set the source property of an Image to getIconUrl("Target App")
where 4. looks something like
QUrl MyClass::getIconUrl(QString appName)
{
// get iconPath from appName
return QUrl::fromLocalFile(iconPath);
}
If things are running, you can add support for
Multiple .desktop locations (there might be a handful or so)
Add support for relative paths
Add support for XPM files
You can use QIcon::fromTheme(QString iconName) to find the icon. It works most of the time but it's not as reliable as gtk
