  • WPT file preview in UIWebView iOS fails if contains tables

    I'm writing an app running on iPad iOS 5.1.

    This app connect with a DataSnap REST server in order to get the content of an RTF file generated by WPTOOLS. The DataSnap server returns a TStream.

    If the file contains a table, the preview stops just before the table.

    I've copied the content of WP file in Word: the resulting rtf file shows fine, even if table are rendered without borders.
    I've saved the file in .docx format, and it is rendered with borders too.
    I've created a .rtf test file using Apple TextEdit, with table, and it is rendered fine with borders.

    I've tested rtf files saved with WPT4.255 in a Delphi2007 application and with WPT6.20 in a a Delphi XE application, but the problems still rises: the rendering stops just before the table, and no more text is displayed.

    So I've tried opening these test files in Safari on Lion OS, and they are rendered with borders too.

    Finally, I did the same from iPad Safari and iPhone Safari too: the behavior is the same as in my app: the couple of WPTools files are stop rendered just before the table begins.
    In iPhone I've "Files Lite" app installed, and from the browser I was asked to open the rtf download in "Files app" installed: this application renders the WPT rtf files, but this require a different app than Apple default and a download phase.

    This may be is a big issue: users have a lot of files saved with tables using WPTools.
    Doing a pre-rendering job (i.e. in pdf) is an heavy job with the DataSnap server (in memory allocation and CPU).
    Users are currently saving WPTools rtf files containing tables, and it seems these file will not be rendered by millions of iOS device using native preview.

  • Stack overflow error

    After simple migration from Delphi 2005 to Delphi 2006 (using WPT 4.25 for Delphi 2006), a lot of users got "stack overflow" error and application termination when moving to the bottom of the document by the mouse wheel. Cursor disappear ofter document bottom and application raise a windows form with "Stack overflow" message, then halt.
    Thanks.

  • Delphi 2005

    Questions:

    - Do you confirm actual version of WPT5-D2005 does not support WPReporter?

    - Does WPT4.25 (WPTools+WPReporter) install correctly in Delphi 2005 using PRO version with full source code?

  • Delphi 2005

    Hi Julian,
    is there any news about the "Access violation at address 03238C1E in module 'dcc90.dll'. Read of address 00000000. " error?
    This error raise trying to compile a project using the WPTools 4.25 for D2005.
    Also: what about wPDF 2.50 library for D2005?

    I've seen WPT5.x demo - impressive - and I'm really prone to upgrade, but first step is runnng and testing on D2005 actual application with actual library set (WPTools 4.25+WRReporter+wPDF2.50), so I'm waiting with impatience for this ...

    Thank you a lot and .... HAPPY NEW YEAR, have a great 2005!!
    :)

  • WPTools - the future

    My opinion is that a mix of various programming techniques have to be considered in order to develop a robust-and-effective system.
    Object-oriented code is not the bible: it has many plus but slows down the overall performance and usually it is not the best way to build kernel software with speed requirements. I hope the new version will still have the focus on efficiency.
    Have a good job, Julian!

  • wPDF thumbnails

    Hi Julian,
    it seems that wPDF 2 does not create thumbnails.
    I've this problem in my application, but in the demo project PDFEx.dpr the problem still persists: even if the User select "Create thumbnail" the resulting PDF files does not include them.
    (Delphi 5, WPT 4.20, wPDF 2, Windows XP Pro)
