Can you use a field named End with Class TDataBase ? yes!

[wartiaga]

Hi all,

Is there an error in database.prg in fwh1811? Check the images below. In the previous version these errors do not occur. Thanks.



prg line:
oArqBol:BAIRRO := oArqAsoc:BAIRRO



prg line:
REDEFINE GET oGet06 VAR oArqAsoc:END ID 104 of oFolder:aDialogs[1] picture '@!' COLOR Frente,Fundo update

[carlos vargas]

oArqBol:BAIRRO := oArqAsoc:BAIRRO

para descartar, haria lo siguiente:

Code: Select all  Expand view

?oArqBol:cAlias, select(oArqBol:cAlias)
?oArqAsoc:cAlias, select(oArqAsoc:cAlias)

Carlos this is so strange because in older fivewin works great. The line before this error I do the same thing oArqBol:END := oArqAsoc:END.

[Antonio Linares]

Do you have a field named "end" in your DBFs ?

Try to use a different field name

[wartiaga]

Yes Antonio, in 10 dbfs.
Database is ending the object with End and not End()? Any other solutions to not have to change the dbfs and prgs?
Thank you!

[Antonio Linares]

> End and not End()

Inside Harbour there is no difference for them

You can not have a data and a method with the same name, "()" does not matter, it is just a message to the object

[Antonio Linares]

A workaround would be to remove this method from Class TDataBase:

// METHOD End() INLINE ::Close()

[nageswaragunupudi]

It is clear that we can not use oDBf:End to access value of field named "END" or assign new values to oDbf:End.
Sameway you can not have field names that conflict with any methods of datas of TDatabase/

In such cases, we can rename the field temporarily inside the TDatabase object and use the temporary new name to access/assign values.

For example

Code: Select all  Expand view

oDbf:MapCol( "END", "ENDX" )
? oDbf:EndX
oDbf:EndX := <val>
 

You can safely use oDbf:Endx and it is internally mapped to the field "END"
You can use any name you like.

Note:
Please change the caption "Error in database.prg".
There is NO ERROR in FWH Database.prg.

Thanks for the explanation. I called it an "error" because in older versions of fivewin this problem doesn't occur. What changed in database.prg for this to happen?

Great! Thank you Antonio!

[nageswaragunupudi]

Thanks for the explanation. I called it an "error" because in older versions of fivewin this problem doesn't occur. What changed in database.prg for this to happen?

New method End() which is a synonym for Close() was added.

Ok, thank you Mr. Nages!

[James Bott]

Thanks for the explanation. I called it an "error" because in older versions of fivewin this problem doesn't occur. What changed in database.prg for this to happen?

Actually, it was a change that I suggested. Prior to that, all of FW's objects could be "destroyed" by calling the End() method--except the TDatabase class which used a Close() method, which is the old DBase command to close a file. However, when using objects it helps to use the same method names for similar processes, thus changing the method Close() to End() made data objects consistent with all the other types of objects--just like the New() method is used to create all new objects.

Thus it is not a good idea to try to use any method name as a fieldname in your code.
