One of my stupid questions....

[Cableguy]

Hi guys, it's been a while since i've ben active in the forum, code wise....
I'm stuck in a problem... I'm reading an ini file and have an eror label called "erro", wich gets called if there is any proble accesing the file...But how ca I call the errorlabel upon a condition?

This is my code...
Yes, I know i'm readding teh file 3 times before i use the data...
it's my way of doing things...bare with me on this one..

Sub LoadINI
ErrorLabel(erro)
FileOpen(c,"LusiGES.ini",cRead)
a=FileRead(c)
a=FileRead(c)
a=FileRead(c)
Nome=StrRemove(a,0,5)
'Here I want to test if the resulting string is equal to a known string (my own name), if not, then should be considered an invalid ini file, and jump to the error label.
If Nome<>"Paulo S�rgio Gomes" Then ' then what??? 

FileClose(c)
Erro:
Msgbox("N�o foi possivel ler" & crlf & "o ficheiro LusiGes.ini","Erro de Leitura.",cMsgBoxOK,cMsgBoxExclamation)

End Sub

You could use

If ... Then Goto Erro

[Cableguy]

I tryied that, it errors sayin the the variable erro is used before assigned a value..

I've tested it with this code and it doesn't give any error:

Sub LoadINI
ErrorLabel(erro)
FileOpen(c,"LusiGES.ini",cRead)
a=FileRead(c)
a=FileRead(c)
a=FileRead(c)
Nome=StrRemove(a,0,5)
'Here I want to test if the resulting string is equal to a known string (my own name), if not, then should be considered an invalid ini file, and jump to the error label.
If Nome<>"Paulo S�rgio Gomes" Then Goto Erro' then what??? 

FileClose(c)
Return
Erro:
Msgbox("N�o foi possivel ler" & crlf & "o ficheiro LusiGes.ini","Erro de Leitura.",cMsgBoxOK,cMsgBoxExclamation)

End Sub

[Cableguy]

Sorry EREL, i'm too rusted....
I was typing "go to" instead of goto....it's working now...
Just one more "Stupid" question, to exit the sub before the error label gets executed.., I just tipe "exit", right?

[Erel]

Not so stupid. More of a common mistake.
You should add Return before the error label.

I know it probably woul be a lot worse, mistake wise, but woudn't it be more logical an "ExitSub" keyword?

Don't forget that Subs can return values so that "Return var" is quite logical.
