SubstWrapper UDF - Support Topic

#1 ·  Posted (edited)

I just made new UDF.
This is an UDF wrapper for windows subst command (Associates a path with a drive letter).

Here are  examples:

#include <AutoItConstants.au3>
#include <FileConstants.au3>
#include <MsgBoxConstants.au3>
#include "SubstWrapper.au3"

_Subst_Example1()
;~ _Subst_Example2()

Func _Subst_Example1()
    _Subst_SetCallback(ConsoleWrite)

    ; Generate LONG FILE NAME
    Local $sFileName = ''
    For $i = 1 To 25
        $sFileName &= '1234567890'
    Next
    $sFileName = $sFileName & '.au3'

    Local $sDestDir = StringLeft(@WindowsDir, 1) & ':\Subst_testing' ; usually C:\Subst_testing
    Local $sDest = $sDestDir & '\' & $sFileName
    MsgBox($MB_OK, _
            StringLen($sFileName) & ' ' & StringLen($sDest), _
            FileCopy(@ScriptFullPath, $sDest, $FC_CREATEPATH + $FC_OVERWRITE) _
            )

    ; Of course according to: https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx
    ; To specify an extended-length path, use the "\\?\" prefix. For example, "\\?\D:\very long path".
    ;
    ; I could use
    ;       FileCopy(@ScriptFullPath, "\\?\" & $sDest, $FC_CREATEPATH + $FC_OVERWRITE)
    ;
    ; but for showing how SubstWrapper.au3 works I will not add "\\?\"  prefix

    Local $sDrive = 'r'
    $sDest = $sDrive & ':\' & $sFileName
    DirCreate($sDestDir)

    ; Associates a path with a drive letter.
    _Subst_Add($sDrive, $sDestDir)
    If @error Then MsgBox($MB_ICONERROR, '_Subst_Add', '@error = ' & @error & @CRLF & '@extended = ' & @extended)

    ShellExecute($sDrive & ':')

    MsgBox($MB_OK, _
            StringLen($sFileName) & ' ' & StringLen($sDest), _
            FileCopy(@ScriptFullPath, $sDest, $FC_OVERWRITE) _
            )

    MsgBox($MB_OK, 'Waiting', _
            'Check the content of ' & $sDrive & ':' & @CRLF & _
            'When you Click "OK" button the ' & $sDrive & ': will be Deleted ' & @CRLF & _
            'REMARK: Content should be save - not deleted' _
            )

    ; Deletes a substituted (virtual) drive.
    _Subst_Del($sDrive)
    If @error Then MsgBox($MB_ICONERROR, '_Subst_Del', '@error = ' & @error & @CRLF & '@extended = ' & @extended)

EndFunc   ;==>_Subst_Example1

Func _Subst_Example2()
    _Subst_SetCallback(ConsoleWrite)

    ; set drive letter with out colon and backspace
    Local $sDrive = 's'

    ; Associates a path with a drive letter.
    _Subst_Add($sDrive, @WorkingDir)
    If @error Then MsgBox($MB_ICONERROR, '_Subst_Add', '@error = ' & @error & @CRLF & '@extended = ' & @extended)

    ; list of current virtual drives
    Local $aResult_outer = _Subst_ListToArray()
    If @error Then MsgBox($MB_ICONERROR, '_Subst_List', '@error = ' & @error & @CRLF & '@extended = ' & @extended)
    Local $aResult_inner
    For $iOuter_idx = 0 To UBound($aResult_outer) - 1
        $aResult_inner = $aResult_outer[$iOuter_idx]
        _ArrayDisplay($aResult_inner, '$aResult_inner[' & $iOuter_idx & ']')
    Next

    ShellExecute($sDrive & ':')

    MsgBox($MB_OK, 'Waiting', _
            'Check the content of ' & $sDrive & ':' & @CRLF & _
            'When you Click "OK" button the ' & $sDrive & ': will be Deleted ' & @CRLF & _
            'REMARK: Content should be save - not deleted' _
            )

    ; Deletes a substituted (virtual) drive.
    _Subst_Del($sDrive)
    If @error Then MsgBox($MB_ICONERROR, '_Subst_Del', '@error = ' & @error & @CRLF & '@extended = ' & @extended)

    ; list of current virtual drives
    _Subst_List()
    If @error Then MsgBox($MB_ICONERROR, '_Subst_List', '@error = ' & @error & @CRLF & '@extended = ' & @extended)

EndFunc   ;==>_Subst_Example2

The second example also works (just uncomment them).

Have fun.

@mLipok,

i've had a bad past experience with subst when it comes to operations on too long paths. nothing solidly reproducible, but a lot of seemingly-unresolved failures of file operations functions. so i came up with this UDF - have you not noticed it?

 

(which, b.t.w, is listed in the Wiki page of User Defined Functions.)

you might want to give it a try.

Yeah, I know that even If I use subst then filename could be larger than 256 chars.
For my purposes temporarily just how to use the prefix in one function.
But it's quite possible that in the future I would use your UDF.

This SubstWrapper was an idea that did not work out, but I decided to finish it, I hope that with the benefit for the community.

      I encourted a problem with FilePath Length ( > 260 chars)
      https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx
       
      As a solution I try to use Windows "subst" command:
      And I make a wrraper UDF for this.
      Here is example how to use:
      #include <AutoItConstants.au3> #include <FileConstants.au3> #include <MsgBoxConstants.au3> #include "SubstWrapper.au3" _Subst_Example1() ;~ _Subst_Example2() Func _Subst_Example1() _Subst_SetCallback(ConsoleWrite) ; Generate LONG FILE NAME Local $sFileName = '' For $i = 1 To 25 $sFileName &= '1234567890' Next $sFileName = $sFileName & '.au3' Local $sDestDir = StringLeft(@WindowsDir, 1) & ':\Subst_testing' ; usually C:\Subst_testing Local $sDest = $sDestDir & '\' & $sFileName MsgBox($MB_OK, _ StringLen($sFileName) & ' ' & StringLen($sDest), _ FileCopy(@ScriptFullPath, $sDest, $FC_CREATEPATH + $FC_OVERWRITE) _ ) ; Of course according to: https://msdn.microsoft.com/en-us/library/windows/desktop/aa365247(v=vs.85).aspx ; To specify an extended-length path, use the "\\?\" prefix. For example, "\\?\D:\very long path". ; ; I could use ; FileCopy(@ScriptFullPath, "\\?\" & $sDest, $FC_CREATEPATH + $FC_OVERWRITE) ; ; but for showing how SubstWrapper.au3 works I will not add "\\?\" prefix Local $sDrive = 'r' $sDest = $sDrive & ':\' & $sFileName DirCreate($sDestDir) ; Associates a path with a drive letter. _Subst_Add($sDrive, $sDestDir) If @error Then MsgBox($MB_ICONERROR, '_Subst_Add', '@error = ' & @error & @CRLF & '@extended = ' & @extended) ShellExecute($sDrive & ':') MsgBox($MB_OK, _ StringLen($sFileName) & ' ' & StringLen($sDest), _ FileCopy(@ScriptFullPath, $sDest, $FC_OVERWRITE) _ ) MsgBox($MB_OK, 'Waiting', _ 'Check the content of ' & $sDrive & ':' & @CRLF & _ 'When you Click "OK" button the ' & $sDrive & ': will be Deleted ' & @CRLF & _ 'REMARK: Content should be save - not deleted' _ ) ; Deletes a substituted (virtual) drive. _Subst_Del($sDrive) If @error Then MsgBox($MB_ICONERROR, '_Subst_Del', '@error = ' & @error & @CRLF & '@extended = ' & @extended) EndFunc ;==>_Subst_Example1 Func _Subst_Example2() _Subst_SetCallback(ConsoleWrite) ; set drive letter with out colon and backspace Local $sDrive = 's' ; Associates a path with a drive letter. _Subst_Add($sDrive, @WorkingDir) If @error Then MsgBox($MB_ICONERROR, '_Subst_Add', '@error = ' & @error & @CRLF & '@extended = ' & @extended) ; list of current virtual drives Local $aResult_outer = _Subst_ListToArray() If @error Then MsgBox($MB_ICONERROR, '_Subst_List', '@error = ' & @error & @CRLF & '@extended = ' & @extended) Local $aResult_inner For $iOuter_idx = 0 To UBound($aResult_outer) - 1 $aResult_inner = $aResult_outer[$iOuter_idx] _ArrayDisplay($aResult_inner, '$aResult_inner[' & $iOuter_idx & ']') Next ShellExecute($sDrive & ':') MsgBox($MB_OK, 'Waiting', _ 'Check the content of ' & $sDrive & ':' & @CRLF & _ 'When you Click "OK" button the ' & $sDrive & ': will be Deleted ' & @CRLF & _ 'REMARK: Content should be save - not deleted' _ ) ; Deletes a substituted (virtual) drive. _Subst_Del($sDrive) If @error Then MsgBox($MB_ICONERROR, '_Subst_Del', '@error = ' & @error & @CRLF & '@extended = ' & @extended) ; list of current virtual drives _Subst_List() If @error Then MsgBox($MB_ICONERROR, '_Subst_List', '@error = ' & @error & @CRLF & '@extended = ' & @extended) EndFunc ;==>_Subst_Example2
