I've encountered a problem with a single file where I cannot retrieve it's Date-time. So far my code has worked well for over 30 files, but this one is a mystery I cannot debug myself due to insufficient Au3 knowledge.
In line 11 "_Date_Time_FileTimeToArray" is called and for this particular file it sets the @error to 10. I don't know what that error code means, but it's not set by the _Date functions themselves I think.
Overall, it could be a problem caused by any of the functions below, how can I properly debug this? / Does anybody know a what's causing this?
_WinAPI_CreateFile() / _Date_Time_GetFileTime() / _Date_Time_FileTimeToArray()
Func _SetFileTimes($sFilePath) Local $monthNumber = ["", "January", "February", "March", "April", "May", "Juny", "July", "August", "September", "October", "November", "December"] Local $dayNumber = ["Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"] Local $fHandle = _WinAPI_CreateFile($sFilePath, 2, 2) ; read-only ; may NOT return a valid date for some reason! TODO Local $fTagFILETIME = _Date_Time_GetFileTime($fHandle) _WinAPI_CloseHandle($fHandle) ; This will return an empty array if theres no valid date $fModTime = _Date_Time_FileTimeToArray($fTagFILETIME) ; last Modified if @error <> 10 then Local $year = $fModTime Local $month = $fModTime Local $day = $fModTime Local $hour = $fModTime Local $min = $fModTime Local $sec = $fModTime Local $ms = $fModTime Local $weekday = $fModTime Global $prettyTimestamp = StringFormat("%s, %s %d, %04d %02d:%02d:%02d", $dayNumber[$weekday], $monthNumber[$month], $day, $year, $hour, $min, $sec) Global $uploadDate = StringFormat("%04d-%02d-%02d", $year, $month, $day) $fModTime = _Date_Time_FileTimeToArray(_Date_Time_FileTimeToLocalFileTime($fTagFILETIME)) ; last Modified Local $year = $fModTime Local $month = $fModTime Local $day = $fModTime Local $hour = $fModTime Local $min = $fModTime Local $sec = $fModTime Local $ms = $fModTime Local $weekday = $fModTime ; GetUnixTime accounts for Local time, hence feed it local time Global $unixTimestamp = _GetUnixTime($year &"/"& $month &"/"& $day &" "& $hour&":"& $min &":"& $sec) else Global $prettyTimestamp = "N/A" Global $uploadDate = "" Global $unixTimestamp = "N/A" endif endfunc
_GetUnixTime returned the year 1601 start date, showing that $fModTime is probably equal 0. (But Why?)
The file reports these dates in Explorer, it's on local NTFS drive:

I have this piece code that works with Excel file and finds the column name where is a specific named range located.
Local $Column = Null $Column = _Excel_ColumnToLetter($oWorkbook.Sheets("MySheetName").Range("MyRangeName").Column) If @error Then $Column = Null SetError(0) Else ;Proceed... EndIf It works properly if the named range exists in the Excel file, I do get the column name and the "Proceed" part is correctly executed. If the named range is not present in the Excel file, I would expect the If @error part to set the variable to Null and then follow with the rest of the function after EndIf. Instead, the script stops and I get this error:
"C:\test\script_021.au3" (1184) : ==> The requested action with this object has failed.: $Column = _Excel_ColumnToLetter($oWorkbook.Sheets("MySheetName").Range("MyRangeName").Column) $Column = _Excel_ColumnToLetter($oWorkbook.Sheets("MySheetName")^ ERROR What am I doing wrong here? Is it possible that failure to set the variable doesn't set the @error? Push in the right direction would be much appreciated. Thanks!
Bit of a fun one with querying WMI objects and setting errors within a function. Below is example code that I've used from JSThePatriot previous UDFs but the example would apply to many other scenarios. Basically the SetError should be called if $colItems is not an object as a result of the WMI query. This is then used to create a corresponding error message.
I've tried disabling WMIC thus forcing it to not be an object, but rather than catching the error and telling me about it, the code simply fails therefore surely making the purpose of the logging useless?? I've experienced this before but in other languages such as java i would use a try catch etc and get around this....any suggestions for its use in AutoIT?

Hello, I recently opened a bug report without reading the Helpfile... My bad . After @Melba23's gentle reminder, I was curious about why it was like that.
It is about SetError's behaviour. This is the example from the bug report:
Example() If @error Then ConsoleWrite("Error" & @CRLF) Else ConsoleWrite("No Error" & @CRLF) EndIf Func Example() SetError(1) Sleep(1000) EndFunc What I tried to do is set Example's (my user defined function's) @error value to 1... but the value set by SetError is cleared after calling a function, I wonder why? Why should calling to an external function effect my function's @error which is set when my function returns.
Setting the error of a UDF in advance by using SetError makes sense... but I cannot find a reason why calling a function should clear it? Please note that I am not talking about @error, I am talking about the @error set by my function when it ends/returns!
I hope someone can enlighten me, thanks for the answers in advance!
P.S I tried to explain my best but my English is not very good and I didn't feel like I did a good job explaining today, so please pardon any mistakes that I have made
