The Open local document button opens a supported file when the button is clicked. The Filename property sets the name and relative path of the file. Files are relative to the folder where the MegunoLink project is saved. The file types supported are:

  • .txt text file
  • .pdf Adobe® Acrobat file
  • .html web page file
  • .exe program
  • .bat batch file

Documents are opened in the file type’s default application; the same program that is opened when you double-click the file in Windows Explorer.

The file to open is set using the Filename property. The Filename must be relative to the MegunoLink project file directory. Use the Arguments property to include parameters that will be included when the document is opened. Arguments can include expressions involving other controls in the interface panel.
