ctlUniRichTextBoxXP.RichEditVersion Function

Many features are not supported by the version 1.0 so we suggest you to check the RichEdit version and propose the user to install this file if needed: http://www.hexagora.com/download/support/richupd.exe (update for version 3.0)

The original specification for rich edit controls is Rich Edit 1.0; the current specification is Rich Edit 3.0. Each version of rich edit is a superset of the preceding one, except that only Asian builds of Rich Edit 1.0 have a vertical text option. Before creating a rich edit control, you should call the LoadLibrary function to verify which version of Rich Edit is installed. The following table shows which DLL corresponds with which version of rich edit. Note that the name of the file did not change from version 2.0 to version 3.0. This allows version 2.0 to be upgraded to version 3.0 without breaking existing code.

Rich Edit version DLL
1.0 Riched32.dll (Win95)
2.0 Riched20.dll (Win98/WinNT4)
3.0 Riched20.dll (WinMe/Win2K/WinXP)
