so i open an existing xls by using excel_openbook, and other program cant find it by using booklist()

can anybody tell how it POSSIBLE?

Do you have any code we can inspect?  Can you isolate the code that is producing the problem and share it?

[vkrisz81]

so i tried to get opened excel's title by using winlist, and user excel attach  with parameter "Title" and still nothing

so excel UDF in this way USELESS

in my opinion cant be usefull something what sometimes works, sometimes not in same way.. trustless

Instead of being an ass about it, post your code so we can test it ourselves.

sure i post but not much code needed, only 2 rows the whole what you can find out also by the given datas but here you are

this bug is present here since a year almost.. so i am not suprised that this does not work properly..

my main program opens file

$excel=_Excel_Open()
_Excel_BookOpen($excel,@ScriptDir&"\_work.xls")

and client try reach this and handle cells in common excel file:

$a=_Excel_BookList()
_ArrayDisplay($a)
$excel=_Excel_BookAttach("_work.xls","filename")

a delivers NOTHING, as if already opened excel would not exist..

but there is

i tried open pre the excel and run the program after to link but nothing

and sometimes it finds instant

on other machine it works.. here  NOW not

but how can program can be good if it works if it wants not if it needed

 

Instead of being an ass about it, post your code so we can test it ourselves.

if it would work at you, that would not solve my problem that sometimes works NOT

unstable

 

i also tried use winlist to get excel's title and try attach by using title but also unsuccess!

$a=WinList("[REGEXPTITLE:(?i)(.*_work.*|.*Microsoft Excel.*)]")
    $excel=_Excel_BookAttach($a[1][0],"Title")

 

 

as i remember it works only first time, after it never till i restart whole computer..

so excel attach only find when you ask it first, never more

only if restart whole machine.. so ridicoulos

You have to do two things:

• Add error checking to your script. Every _Excel* function sets @error in case of a problem. Check and only keep on processing when @error = 0
• You have to save the returned object so you can access it later. Else it will be dropped. means:

$oExcel=_Excel_Open()
If @error Then Exit MsgBox(0, "Error!", "_Excel_Open failed with error " & @error)
$oWorkBook = _Excel_BookOpen($oExcel, @ScriptDir & "\_work.xls")
If @error Then Exit MsgBox(0, "Error!", "_Excel_BookOpen failed with error " & @error)

sometimes shows i have no acces to that excel file because other program use it..

sure other use because more program must use same excel to handle common datas

best way would be if i would be able shared memory addresses.. but i cant solve it, so i need this broken method to share data between programs

Glad you removed your comments from Melba's and my posts. You would have been in big trouble if a Mod would have noticed them.

Now, as you have cooled down, lets see how to help you solve your problem:

sure other use because more program must use same excel to handle common datas

Excel can only have multiple people use the same Workbook when the access diferent worksheets. So this is quiete limited.

First question:
Do all users need write access to this workbook or would read access be fine as well?

vkrisz81,

It seems you are lucky that I was on the golf course this morning. I will be watching you closely from now on.
