I can't find this in the tutorial book or the concepts book.
We have code like
IF TABLE_Example[TABLE_Example].COL_Title <> "" THEN
//do something
END
We also have code like
IF TABLE_Example.COL_Title <> "" THEN
//do something
END
There seems to be no difference.
But trying to use TABLE_Example[TABLE_Example]..FontStrikeOut = True works,
trying to use TABLE_Example..FontStrikeOut does not work? (I'm getting an compile error: The 'FontStrikeOut' property does not apply to this type of control.)
So I'm missing something. What is the difference between the two? |

Hi.
TABLE_Example refer to control table.
TABLE_Example[TABLE_Example] refer to current table line, the last add to table for example.
The properties for table and line are diferents.

Thanks for the answer.
So TABLE_Example is different from TABLE_Example[TABLE_Example], but there is really no difference between using TABLE_Example.COL_Title and TABLE_Example[TABLE_Example].COL_Title as both will point to the same column of the current table line.

Christine,
Both will work but under some situation will fail you, like if the table is empty and you have code on the "Selecting a table row" process of the table control.
Better practice would be something like.
nRow is int = tableselect(TableExample) //Or if you are looping thru the table use "Currentsubscript" nRow is int = CurrentSubscript(TableExample) //This would be for code used on the "Displaying a table row" of a table control if nRow = -1 return (Or error message) TableExample[nRow]..FontBold = true DW |

Thanks a lot for this explanation. It is clearer now for me.
