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.</p> <p><strong>Convert7to8</strong> 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").</p> <p>The following list explains the changes needed to convert the project and why they are necessary:</p> <p><strong>Class names and GUIDs have changed</strong></p> <p>This affects declarations made inside .frm and .vbp files. To see the GUIDs that have changed please open up the Convert7to8.frm file in notepad and the GUIDs will appear for the old and new Chart versions.</p> <p>The following table lists the class control names that have changed from <strong>Chart7</strong> to <strong>Chart8</strong>:</p> <p> </p> <table cellspacing="0" cellpadding="0" border="0"> <tbody> <tr> <td valign="top" width="295"> <p><strong>Chart7 Class Control Names:</strong></p> </td> <td valign="top" width="295"> <p><strong>Chart8 Class Control Names:</strong></p> </td> </tr> <tr> <td valign="top" width="295"> <p>C1Chart2D7.Chart2D</p> </td> <td valign="top" width="295"> <p>C1Chart2D8.Chart2D</p> </td> </tr> <tr> <td valign="top" width="295"> <p>C1Chart3D7.Chart3D</p> </td> <td valign="top" width="295"> <p>C1Chart3D8.Chart3D</p> </td> </tr> <tr> <td valign="top" width="295"> <p>C1Chart2D7U.Chart2D</p> </td> <td valign="top" width="295"> <p>C1Chart2D8U.Chart2D</p> </td> </tr> <tr> <td valign="top" width="295"> <p>C1Chart3D7U.Chart3D</p> </td> <td valign="top" width="295"> <p>C1Chart3D8U.Chart3D</p> </td> </tr> </tbody> </table> <a name="seealsobookmark"></a> </div> <div id="FooterContent"> <p> </p><p> </p><hr style="height: 1px"><p>Copyright (c) <script type="text/javascript"> var theDate=new Date() document.write(theDate.getFullYear()) </script> GrapeCity, inc.
