i need help please - New to autoIt


Recommended Posts

i have a script where i want to use if function to do something but i don't know how to use it, can anybody help me?

here's the code:

;  $conn is a variable that opens a connection to the database
;  $rs is a ADODB Object
;=============================

$Query = "Select * from table1"
$rs = $conn.Execute ($Query)
$array = $rs.GetRows()

the problem is that when the $rs variable is empty the script stops.

i want to know how to check if this variable is empty and holds no data

thank you for the correction,

i tried the previous one but it didn't work for me the script stopped as well, i hope you could bear with me a while

here the code i wrote:

if $rs = "" Then
    ShowInfo("Found No Data..", "500", "0")  ;show a message using another function
Else
    $array = $rs.GetRows()

it stopped at $rs.GetRows()

is there any thing else i can try?

$rsis a rowset object, not an elementary AutoIt variable.

You can test for an empty rowset easily with:

$iNumberOfRows = $rs.RecordCount

This wonderful site allows debugging and testing regular expressions (many flavors available). An absolute must have in your bookmarks.

thank you for helping me, i tried it and the :

$iNumberOfRows = $rs.RecordCount

always gives result = -1 meaning that the "$iNumberOfRows" is equal -1 when $rs is empty and when it is full

i'm still trying to find a way to check when it's empty | with your help of course :)

I found it ..

I found it

i found it in another topic, the topic was discussing something bigger than just my case but someone wrote it and i tried it an it worked.

here it is:

if not $rs.EOF then

the secret is the "EOF" that was placed after the variable i checks if it's empty.

thank you all.

i don't know why when i write a dot "." the available parameters aren't shown automatically, i know some of them are shown but not everything.

but a great scripting language very very very useful :)
