_EDPOSINVI

_EdPosInVi() Returns the current visibility of a given caret position from the beginning of file in the editor session passed in <nWHANDL>.

VFP Syntax

lDisplayed = _EdPosInVi(nWHAND, nPosition)

Parameters

[in] nWHAND

Fox-window handle of the editor session in question. If nWHANDL is no valid editor-session handle, an error “API call caused an exception” (Error 2028) is raised.

[in] nPosition

Offset position (byte count) from beginning of the file. <nPosition> value is zero-based. CRs @ EOL are counted as well.

Returns

Boolean – TRUE := caret is visible | FALSE := caret is not visible.

Remarks

Note: _EdPosInVi() returns .T. even if the text line holding the caret is only shown partially, like shown below!

VFP Example(s)

Opening an editor session, echoing visibility of caret to _SCREEN:

*\\ Open editor session
*\\   use file content with a lot of wide lines
nWHAND =_EDOPENFIL("TEST.TXT", 1)
? _EDPOSINVI(m.nWHAND, _EDGETPOS(m.nWHAND))
