but  not  write nothing  in console  , like  if   ADO not  connect  

you have some  suggest? 

thankz

Just browsing thru code. The variable $oConnection is local to the function _ConnectDB_gest so it's going to be destroyed when exiting from the function. This doesn't affect the global variable, which never gets assigned anything IMHO.

The help clearly says: "Global can be used to assign to global variables inside a function, but if a local variable (or parameter) has the same name as a global variable, the local variable will be the only one used. It is recommended that local and global variables have distinct names."

Simply remove the Local declaration in the function. To understand why, read again slowly the quoted exerpt from the help I pasted.

Hi @faustf

@jchd Thanks for claryfication for @faustf.

 


I want also add my 0,02$

Func _CloseDB_gest()

    ; CleanUp
    $oRecordset = Null
    _ADO_Connection_Close($oConnection)
    $oConnection = Null

EndFunc   ;==>_CloseDB_gest

$oRecordset - should be always local If you want to clean Up this object you should do it internally in each function.

 

Here are my other remarks and some script refactoring:

; REMARK
; Try to always use: this two line #AutoIt3Wrapper_Au3Check_Parameters and #Tidy_Parameters
; This really help in keeping script clean.
