How to wrap a function with optional parameters?

Recommended Posts

aleeksunder

Hello!

I'm a newbie in AutoIt and want to wrap some internal autoit functions like RegWrite() in way function will display MsgBox with of error happens.

I want to wrap because write error handler becomes really annoying when it comes to code, and I have to write the same code after every RegWrite() call and this becomes really ugly. So I just want this:

Local $s_key        = 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control'
Local $s_value_name = 'value1'
Local $s_value_type = 'REG_SZ'
Local $value_data   = 'data1'

RegWrite( $s_key , $s_value_name , $s_value_type, $value_data )

If @error Then
    MsgBox( $MB_ICONERROR , 'ERROR' , 'Error writing registry:' & @CRLF & 'Key: ' & $s_key & @CRLF & 'Value: ' & $s_value_name & @CRLF & 'Type: ' & $s_value_type & @CRLF & 'Data: ' & $value_data & @CRLF & 'ErrorCode: ' & @error )
EndIf


Local $s_key = 'HKEY_CURRENT_USER\Software\MyApp'

RegWrite( $s_key )

If @error Then
    MsgBox( $MB_ICONERROR , 'ERROR' , 'Error writing registry:' & @CRLF & 'Key: ' & $s_key & 'ErrorCode: ' & @error )
EndIf

Becomes into this:

RegistryWrite( 'HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control' , 'value1' , 'REG_SZ' , 'data1' )
RegistryWrite( 'HKEY_CURRENT_USER\Software\MyApp' )

Func RegistryWrite( $s_key , $s_value_name = NULL , $s_value_type = NULL , $value_data = NULL )

    RegWrite( $s_key , $s_value_name , $s_value_type, $value_data )

    If @error Then

        MsgBox( $MB_ICONERROR , 'ERROR' , 'Error writing registry:' & @CRLF & 'Key: ' & $s_key & @CRLF & 'Value: ' & $s_value_name & @CRLF & 'Type: ' & $s_value_type & @CRLF & 'Data: ' & $value_data & @CRLF & 'ErrorCode: ' & @error )

    EndIf

EndFunc

And I'm just confused how to properly pass the optional parameters to target function as documentation says that NULL can be evaluated as 0 in mathematical expressions. Maybe "Default" or something else is more suitable?

I undersand that I can write separate wrappers for each number of arguments or handle each optional argument value and call target function with exact arguments number, but the goal is to keep code as clean and as simple as possible.

So i have two questions:

1. What is the _proper_ and maybe universal way to pass optional parameters to wrapped functions?

2. Can I achive the same result without wrapping every function? Maybe some AutoIt execution flags to always popup a error that happens and stop execution?

1. Use the default keyword

      Hey there!
       
      Is there a way to detect movement only for 1 specific window?

      HWnd is not really working, it still detects movement in all the windows within the region

      This is my script:
       
      ;Checksum actual HotKeySet("{f2}", 'exit_') MsgBox(0, '', '0') Beep(500, 2000) $Hwnd = WinActive('') while 1 $Checksum = PixelChecksum(211, 650, 1094, 914, 1, $Hwnd) If PixelChecksum(211, 650, 1094, 914, 1, $Hwnd) <> $Checksum Then For $i = 1 To 100 Beep(1000, 50) Next MsgBox(0, '', 'New message!', 1) EndIf WEnd Func exit_() Beep(500, 1000) Exit 0 EndFunc I just want to check whenever a message comes because the app i use doesn't give notifications properly.

      Any help is really appreciated!

      Can you please see whats wrong im doing in the below code? i can read few registry entry but not all for eg, i am able to get value of "Shell" Key from the registry path  but not AutoAdminLogon which has the value of "1", is there any change i have to do to read numeric values?
       Global  $shello = RegRead ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon","Shell" )
       ConsoleWrite("This is Hello"& $shello)
      above command returns proper value , but same command with AutoAdminLogon returns null as shown in below ? infact registry has the value of 1.
       Global  $shello = RegRead ("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon","AutoAdminLogon" )
       ConsoleWrite("This is Hello"& $shello)

      Hello,
      I've been searching on how to select the first row in my database which includes a time column based on the latest start_time date for today's date.
      This is my current code:
      Local $iCurrentDate = _Now() Local $sqlHandle = _dbOpen($sDbPath) Local $aResult, $iRows, $iCols _SQLite_GetTable2d($sqlHandle, "SELECT start_time FROM " & $srawDb & " ORDER BY datetime(start_time) DESC LIMIT 1", $aResult, $iRows, $iCols) _ArrayDisplay($aResult) _dbClose($sDbpath) What it does is it gets the first row entry in the database however it does not select the latest start_time entry in the database, it always select the first row. I've tried changing DESC to ASC to see if that will do it but the issue still remains. Any thoughts on this? Thanks in advance.
       
      *EDIT
      The date format in the database is by MM/DD/YYYY HH:MM:SS.
