CreateProcess with STDIO [Solved]

October 7, 2010

Hiho,

trying to figure out how to get my example Retrieve Unicode results from Console working on x64 I took a look at the $tagSTARTUPINFO. Seems to work fine on x86.

This is the current definition:

Global Const $tagSTARTUPINFO = "int Size;ptr Reserved1;ptr Desktop;ptr Title;int X;int Y;int XSize;int YSize;int XCountChars;" & _
        "int YCountChars;int FillAttribute;int Flags;short ShowWindow;short Reserved2;ptr Reserved3;int StdInput;" & _
        "int StdOutput;int StdError"

MSDN defines the last three elements as handles. This clearly busts the current definition (int).

typedef struct _STARTUPINFO {

DWORD cb;

LPTSTR lpReserved;

LPTSTR lpDesktop;

LPTSTR lpTitle;

DWORD dwX;

DWORD dwY;

DWORD dwXSize;

DWORD dwYSize;

DWORD dwXCountChars;

DWORD dwYCountChars;

DWORD dwFillAttribute;

DWORD dwFlags;

WORD wShowWindow;

WORD cbReserved2;

LPBYTE lpReserved2;

HANDLE hStdInput;

HANDLE hStdOutput;

HANDLE hStdError;

} STARTUPINFO, *LPSTARTUPINFO;

LPTSTR equals ptr? I don't know . Anyone willing to take a look. Here's my current suggestion:

Global Const $tagSTARTUPINFO = "int Size;ptr Reserved1;ptr Desktop;ptr Title;int X;int Y;int XSize;int YSize;int XCountChars;" & _
        "int YCountChars;int FillAttribute;int Flags;short ShowWindow;short Reserved2;ptr Reserved3;handle StdInput;" & _
        "handle StdOutput;handle StdError"

This is the current definition:

No, it's not.

October 7, 2010

According to the UDF help-file... which is not up-to-date... ...

The current StructureConstants.au3 defines it as:

Global Const $tagSTARTUPINFO = "dword Size;ptr Reserved1;ptr Desktop;ptr Title;dword X;dword Y;dword XSize;dword YSize;dword XCountChars;" & _
        "dword YCountChars;dword FillAttribute;dword Flags;word ShowWindow;word Reserved2;ptr Reserved3;handle StdInput;" & _
        "handle StdOutput;handle StdError"

LPTSTR = ptr?

LPBYTE = ptr?

October 7, 2010

MSDN says the following about LPTSTR: "The letter "T" in a type definition, for example, TCHAR or LPTSTR, designates a generic type that can be compiled for either Windows code pages or Unicode." Also has this to say: "An LPWSTR if UNICODE is defined, an LPSTR otherwise." So maybe a wstr* or just a wstr?

Replacing LPTSTR = ptr with LPTSTR = wstr or LPTSTR = wstr* makes the function fail on x86 too. Thanks for the link to MSDN Windows Data Types definitions, something to bookmark , knew it, but didn't remembered it .

Edit:

Here's a working x86 example, fails on x64.

#AutoIt3Wrapper_UseX64=n

; Description:    lists all or preferred files and or folders in a specified path (Similar to using Dir with the /B Switch)
; Syntax:          _FileListToArrayEx($sPath, $sFilter = '*.*', $iFlag = 0, $sExclude = '')
; Parameter(s):     $sPath = Path to generate filelist for
;                   $sFilter = The filter to use. Search the Autoit3 manual for the word "WildCards" For details, support now for multiple searches
;                           Example *.exe; *.txt will find all .exe and .txt files
;                  $iFlag = determines weather to return file or folders or both.
;                   $sExclude = exclude a file from the list by all or part of its name
;                           Example: Unins* will remove all files/folders that start with Unins
;                       $iFlag=0(Default) Return both files and folders
;                      $iFlag=1 Return files Only
;                       $iFlag=2 Return Folders Only
;
; Requirement(s):   None
; Return Value(s):  On Success - Returns an array containing the list of files and folders in the specified path
;                       On Failure - Returns the an empty string "" if no files are found and sets @Error on errors
;                       @Error or @extended = 1 Path not found or invalid
;                       @Error or @extended = 2 Invalid $sFilter or Invalid $sExclude
;                      @Error or @extended = 3 Invalid $iFlag
;                       @Error or @extended = 4 No File(s) Found

$tagSECURITY_ATTRIBUTES or $tagPROCESS_INFORMATION might be another reason why the function fails, but those look quite simple (and correct imho) compared to $tagSTARTUPINFO.

Well, what's the difference between yours $tagSTARTUPINFO_New and original $tagSTARTUPINFO?

There is absolutely nothing wrong with $tagSTARTUPINFO. That's not the reason your code doesn't work.

No difference, it's a spoon-feed testing example. Well, you said ReadFile fails. Never experienced that that before on x64. My assumption is, that the CreateProcess somehow does not work as intended (pipe contains no data). Looking at the involved structures tagSTARTUPINFO seems to be the most complex, and additionally contains some definitions which I can not match to the MSDN documentation at the moment. So, where else to start?

I didn't say ReadFile fails. I said your code fails there. Why? I don't know.

Try making $hReadPipe not inheritable.

Any type definition that starts with "LP" is a pointer type. LPTSTR, LPSTR, LPWSTR are all pointers.

Anyway, what's the point of this? The last time I checked AutoIt allowed STDIO redirection so why are you re-inventing the wheel?

Will do so, thanks for the hint

.

Edit:

Setting this

DllStructSetData($tSecurity, "InheritHandle", False)

makes the function fail even on x86, no win there.

Thanks for the Info. Then it seems that the structure is correct, there has to be another reason why the function fails on x64.

Well, I took this statement "AutoIt doesn't support Unicode from the console" for granted, I think I tested it some time ago (not sure though). And I want the unicode STDOUT. Edited October 7, 2010 by KaFu

October 7, 2010

Facepalm. No, Picard Facepalm.

AutoIt doesn't support it because the console doesn't support it. That should be rather obvious if you spent three seconds thinking about it since why would I arbitrarily limit a UNICODE application to ANSI if I didn't absolutely have to?

October 7, 2010

Because you didn't know of the undocumented cmd.exe /u switch? Give the example in the first post a try, works fine on x86... btw, I think I found a hint, might have to do with x64 redirection, CreateProcess says it can't find the file (cmd.exe)...

October 7, 2010

Because you didn't know of the undocumented cmd.exe /u switch?

Terminology failure on my part. The API's don't support it. Okay, so cmd.exe has an undocumented option that sends UNICODE bytes through a byte stream on the off chance the program reading the stream knows to interpret it that way. Fair enough. Perhaps you should have said similar from the start.

Not sure why this matters. Pretty sure file listing functions can be implemented natively in AutoIt. At least they could the last time I checked. Unless this is one of those silly "Let's jump through a bunch of hoops because AutoIt is too slow" type of things.

; Description:    lists all or preferred files and or folders in a specified path (Similar to using Dir with the /B Switch)
; Syntax:          _FileListToArrayEx($sPath, $sFilter = '*.*', $iFlag = 0, $sExclude = '')
; Parameter(s):     $sPath = Path to generate filelist for
;                   $sFilter = The filter to use. Search the Autoit3 manual for the word "WildCards" For details, support now for multiple searches
;                           Example *.exe; *.txt will find all .exe and .txt files
;                  $iFlag = determines weather to return file or folders or both.
;                   $sExclude = exclude a file from the list by all or part of its name
;                           Example: Unins* will remove all files/folders that start with Unins
;                       $iFlag=0(Default) Return both files and folders
;                      $iFlag=1 Return files Only
;                       $iFlag=2 Return Folders Only
;
; Requirement(s):   None
; Return Value(s):  On Success - Returns an array containing the list of files and folders in the specified path
;                       On Failure - Returns the an empty string "" if no files are found and sets @Error on errors
;                       @Error or @extended = 1 Path not found or invalid
;                       @Error or @extended = 2 Invalid $sFilter or Invalid $sExclude
;                      @Error or @extended = 3 Invalid $iFlag
;                       @Error or @extended = 4 No File(s) Found

;                   $array[1] = 1st File\Folder

;                   $array[3] = 3rd File\Folder
;                   $array[n] = nth File\Folder
;
;                   All files are written to a "reserved" .tmp file (Thanks to gafrost) for the example

Just so everyone is clear, the '/u' switch is documented, and has been in effect since Windows 2000. If you need assistance in using it, here's the command-line help output:

/U  Causes the output of internal commands to a pipe or file to be Unicode

Nice

, thanks a lot, seems to work fine now
