Hi, how can I detect the Row/Col-Position under my mouse (on MouseMove-Event, if I have X/Y-Coordinates)? |

// Returns the row and col (Not validated) for a specific point. Use
// CalcValidDispCol for validation.
// Parameters:
// pt : [in] The point in client co-ordinate.
// pRow : [out] The out parameter contains the calculated
// document row.
// pCol : [out] The out parameter contains the calculated col.
// pDispRow : [out] The out parameter contains the calculated
// visible row.
// pDispCol : [out] The out parameter contains the calculated
// visible col.
// bVirtualSpace : [in] Set TRUE if virtual space is enabled
// (cursor can be paced in any place after line end).
// Returns:
// BOOL : True if point was out of bound and index was corrected
BOOL RowColFromPoint(CPoint pt, int *pRow, int *pCol, int *pDispRow = NULL, int *pDispCol = NULL, BOOL bVirtualSpace = -1);

You can use event CurPosChanged(long nNewRow, long nNewCol);
TextChanged(long nRowFrom, long nRowTo, long nActions); Open your VB Object Browser and look ------------- Mark Doubson, Ph.D. |

Sorry, but I think you dont understand what I want!
Both Events fires ONLY if I've a focus inside the control. That's not what I need! I need Row/Col-Position under the mouse-pointer to set the cursor by code (!). What I already have are the X/Y-Coordinates - and NO FOCUS inside the SyntexEditor. |

if you need to use to expose function RowColFromPoint to ActiveX - open Issue and ask about such feature. I can do it for ver 13.1 ------------- Mark Doubson, Ph.D. |

I also done with new ActiveX function: long POS = RowColCodeFromPoint(long X, long Y)
return POS as nNewRow * 1000 + nNewCol - need to decode back to use
I already changed syntax to
BOOL RowColCodeFromPoint(long x, long y, long* row, long* col)
- no need to decode and unrestricted columns range ------------- Mark Doubson, Ph.D. |
