This whitepaper introduces the Tablet PC and discusses developing applications using Microsoft Visual FoxPro to target the Tablet PC. While this works very well, I also have to point out a limitation of this approach: In Visual FoxPro, we can only attach the InkOverlay class to forms since they are the only objects that expose (or have) window handles. This is not the case in most Windows applications where practically all controls are implemented as separate windows (although they do not look like it). Visual FoxPro does not use a “windowed” approach for generating controls. Instead, controls are painted on the background of the form (this behavior is a reminder that VFP once used to support the Macintosh platform…). This prevents us from attaching the InkOverlay class to controls such as textboxes or containers as we could in other environments. This is unfortunate because only in very rare occasions do we want the whole form ink enabled. (Even if we did we would likely want toolbar buttons or some other controls on the form that we wouldn’t want to ink over.)
