All errors handling

[gahhon]

_Metro_SplashTextScreen(1, "", $iMsg)
AdlibRegister("_Metro_LoopInProgress")
DirRemove($DIR_WA_FOLDER, 1)
Local $iCopy = _WinAPI_ShellFileOperation($CUR_WA_FOLDER, $DIR_WA_FOLDER, $FO_COPY, BitOr($FOF_SIMPLEPROGRESS, $FOF_NOCONFIRMMKDIR))
AdlibUnRegister("_Metro_LoopInProgress")
_Metro_SplashTextScree
If @error Then
    _Metro_MsgBox(0, "", $iCopy)
    _FileWriteLog($LOG_INSTALLATION, "Error: " & $iCopy)
Else
    _Metro_MsgBox(0, "", "Application is up to date!")
    _FileWriteLog($LOG_INSTALLATION, "Debug: Application is up to date.")
EndIf

According to the help file of _WinAPI_ShellFileOperation there are a lot of failure and error code. But how can I handle all of them and display corresponding error message based on the help file?

The incident is like this:
I'll lock the folder with permission, so when I execute the _WinAPI_ShellFileOperation to copy and overwrite the folder contents, it popped me an error message saying that permission issue to caused I can't access the folder and overwrite the contents.

Then I clicked Cancel button, and my AutoIT application exit immediately and it's not execute the function _Metro_MsgBox(0, "", $iCopy) to display the message.

 

Anyway, I did also tried the code below, the it still display "Application is up to date!"
According to the help file, 120 - Security settings denied access to the source.

If @error = 120 Then
    _Metro_MsgBox(0, "", $iCopy)
    _FileWriteLog($LOG_INSTALLATION, "Error: " & $iCopy)
Else
    _Metro_MsgBox(0, "", "Application is up to date!")
    _FileWriteLog($LOG_INSTALLATION, "Debug: Application is up to date.")
EndIf

You could try adding @error to the log, or to a consolewrite to see what number it gives, maybe it's not 120.

You could also do something like

If $icopy = @error Then

I have no idea why can't use ConsoleWrite because it don't print anything. But I try display it via _Metro_MsgBox and it showed "10"
Then I tried If @error = 10 Then display the corresponding error message, but it still jump to "Application is up to date!"

Local $iCopy = _WinAPI_ShellFileOperation($CUR_WA_FOLDER, $DIR_WA_FOLDER, $FO_COPY, BitOr($FOF_SIMPLEPROGRESS, $FOF_NOCONFIRMMKDIR))
_Metro_MsgBox(0, "", @error & ' - ' & $iCopy)

Hi gahhon,
Don't forget that @error is reassigned to 0 each time a new function is encountered (help file, topic SetError)
So trying to reuse @error a few lines after it happened often fails. Just keep it in a variable immediately after it occurs or you'll experience this kind of issue :
 

#include <MsgBoxConstants.au3>

Local $sFileRead = FileRead("C:\temp\this file name doesn't exist.txt")
If @error Then
   MsgBox($MB_ICONERROR + $MB_TOPMOST, "2nd script", "@error = " & @error) ; displays 1
   MsgBox($MB_ICONERROR + $MB_TOPMOST, "2nd script", "@error = " & @error) ; displays 0
Endif

Endif

 

So you are saying that I should store the error code and the error message when after executed the particular function?

All right, but I do have one question that error is actually don't declare in the help file, so I don't get any error message from the help file.
It is normal? So that I can declare my own error message?
