Here's a hex-editor's snooping of an 'asdfasdfasd' caption for the RtfLabel control I used for testing: FRX file of a form with this UserControl.

I've looked, and this property is stored in the. Within the UserControl, this text is actually managed in a module variable named m_RTFCode (a string), and it's stored as a property named RTFCode. I've examined things, and the RTF caption text is just stored in the TextRTF property of the RTB that's part of the UserControl. (Ok ok, my bad back in 1999.) And now, this font is scattered throughout where these controls are used (which is extensive). This control has always defaulted to the MS Sans Serif font. When in design mode, there's a little editor that can pop up (when 'Edit' is clicked on the context menu of the control) which allows you to type (or Copy-Paste from WordPad) text that's 'rich'.

As you might guess, they're just controls that allow RTF text on a button or label caption. I've got these two UserControls I've used for decades (and wrote a LONG time ago). Just as an FYI, I'm talking about 100s of forms, so source code editing isn't a good choice.

Okay, for the most part, things are going fine with me swapping out MS Sans Serif with Microsoft Sans Serif during runtime (allowing me to avoid a huge source code editing job).
