| ComponentOne WebChart 8.0 > Upgrading From Previous Versions |
Visual Basic projects that use WebChart 7.0 may be upgraded to WebChart 8.0 using the conversion utility provided in the distribution package.
The conversion utility is a Visual Basic program called Convert7to8, and its source code is included should you want to see exactly what it does. It is installed to C:\Program Files\ComponentOne\Studio for ActiveX\Utilities by default. Please note that it may be installed elsewhere if you installed the product to another location.
Convert7to8 reads the name of an existing Visual Basic project, parses the names of all forms, then makes all the changes needed to each file. The routine saves the original files with a "bak" extension that is appended to the original file name (e.g., "Form1.frm" becomes "Form1.frm.bak").
