Report Templates: GDI to DMP converter

edited January 2009 in FastReport 4.0
Please test my GDI to DMP converter
The size of objects will have to adjust, from the script you must remove code, referring to objects that are not exists in the DMP reports

    good work, I do not know why the call to convert the method generates an exception "Invalid pointer operation" but the document is converted correctly.

    Good work indeed.

    I have done many report conversions using notepad.

    Just open GDI fr3 file in notepad and use find and replace tool to replace

    TfrxMemoView to TfrxDMPMemoView

    and

    TfrxReportPage to TfrxDMPPage

    save file and thats all.

    Is there an update for FR5?
    The code above does not work with FR5.

Rich Text Editor. To edit a paragraph's style, hit tab to get to the paragraph menu. From there you will be able to pick one style. Nothing defaults to paragraph. An inline formatting menu will show up when you select text. Hit tab to get into that menu. Some elements, such as rich link embeds, images, loading indicators, and error messages may get inserted into the editor. You may navigate to these using the arrow keys inside of the editor and delete them with the delete or backspace key.
