The software allows you to create, edit and convert PDF files with ease. Adobe Acrobat Pro DC is a great example, and it supports both Windows and Mac devices. LibreOffice can be used like this for batch conversion (it's slow, though): soffice -invisible -convert-to xls test.Adobe not only invented the trusty PDF document in the first place, but the company has also created some top-notch apps to manage them. The conversion tool could be bundled with your application or specified as a prerequisite, and controlled via Doc:QProcess. If all else fails, there is always the option of using an existing tool to automatically convert between Excel files and a more manageable format, and let your Qt application deal with that format instead. Third-party libraries can help you in dealing with the container format that wraps the actual XML files: Note that these libraries differ in their scope and general approach to the problem.įiles using the XML-based (.xlsx) format could be processed using Qt's XML handling classes (see Handling Document Formats). Using independent parser/writer librariesįor a more portable solution, you could take a look at some of the available third-party C/C++ libraries for parsing/writing Excel files: Furthermore, the Engine should not be confused with the MS Access Runtime which contains the Engine.
#MAC WIKI READER INSTALL#
That’s why you maybe install both versions to avoid problems.
#MAC WIKI READER 64 BIT#
In Addition, you should regard that a 64 bit application can only use the 64 bit Engine and so for 32 bit accordingly.
The Engine is maybe distributed with a MS Office Access installation, but on this should not be relied on. You can find it here: Microsoft Access Database Engine 2010. NOTE: To use ODBC on Windows, the MS Access Database Engine has to be installed. If a few rows contain text and the rest of them contain floating numbers, sql will make the text appear and will make the numbers disappear. Keep in mind that you are using a database and that each column has his own datatype, so if your second row contains text and your third row contains numbers, sql will pick one of these datatypes. It works for *.xls and *.xlsx and the other excel file formats.īy default OBDC uses the first row as names for the columns, you are supposed to be able to change this with the 'FirstRowHasNames' option in the connection settings, however there is a bug (see KB288343). The above code print all of column1's values to the debug output. QSqlDatabase::removeDatabase("xlsx_connection") QString column1= query.value(0).toString() QSqlQuery query("select * from ",db) // Select range, place A1:B5 after $ QSqlDatabase db = QSqlDatabase::addDatabase("QODBC", "xlsx_connection") ĭb.setDatabaseName("DRIVER= DBQ=" + QString("c:\\path\\to\\your\\file\\file.xlsx")) To read an Excel file with ODBC (tested on Windows 7 with QT 4.7.1 and Windows 10 with QT 5.7) : For an introductory code example (and a way to list the API provided by the Excel COM object), consult this how-to. If you are exclusively targeting the Windows platform and Microsoft Excel will be installed on all target machines, then you can use Qt's ActiveX framework to access Excel's spreadsheet processing functionality through OLE automation.
