hi,

i can show Property of File like "FILEVERSION"


now when have Multi-Media File i got "more" Information ...

but how to "get" these Information

[Jimmy]

hi,

have ask ChatGPT

Can you show me the code of a program written in the Harbour language that show video Property of SHELLEXECUTEINFO ?

have not try (yet) if CODE can be compile ...

hi Antonio,

CODE written by ChatGPT look fine
CODE by ChatGPT does compile fine

but Result does not make (much) Sense ...

[Antonio Linares]

The call to function ShellExecuteExA() is missing, please ask chatGPT again asking to include such call

I just did it and this answer seems ok to me

Code: Select all  Expand view

// Call the ShellExecuteExA function using the SHELLEXECUTEINFO structure
BOOL bResult = ShellExecuteExA( &sei );

// Set the result of the function call in the array
hb_arraySetL( pArray, 17, bResult );

[Jimmy]

hi Antonio,

i try

Can you show me the code of a program written in the Harbour language that show video Property of SHELLEXECUTEINFO which use ShellExecuteExA and return hb_arraySetL ?

and got

Code: Select all  Expand view

#include "hbapi.h"
#include "hbvm.h"
#include "shellapi.h"

HB_FUNC( SHELLEXECUTEINFO )
{
   SHELLEXECUTEINFO sei;
   sei.cbSize = sizeof( SHELLEXECUTEINFO );
   sei.fMask = SEE_MASK_NOCLOSEPROCESS;
   sei.hwnd = NULL;
   sei.lpVerb = NULL;
   sei.lpFile = ( LPCTSTR ) hb_parc( 1 );
   sei.lpParameters = ( LPCTSTR ) hb_parc( 2 );
   sei.lpDirectory = ( LPCTSTR ) hb_parc( 3 );
   sei.nShow = SW_SHOW;
   sei.hInstApp = NULL;
   sei.lpIDList = NULL;
   sei.lpClass = NULL;
   sei.hkeyClass = NULL;
   sei.dwHotKey = 0;
   sei.hIcon = NULL;
   sei.hProcess = NULL;

   if( ShellExecuteExA( &sei ) )
   {
      PHB_ITEM pArray = hb_itemArrayNew( 2 );
      hb_arraySetL( pArray, 1, TRUE );
      hb_arraySetNInt( pArray, 2, ( HB_MAXINT ) sei.hProcess );
      hb_itemReturnRelease( pArray );
   }
   else
   {
      PHB_ITEM pArray = hb_itemArrayNew( 2 );
      hb_arraySetL( pArray, 1, FALSE );
      hb_arraySetNInt( pArray, 2, 0 );
      hb_itemReturnRelease( pArray );
   }
}

it does compile and run ...
it does "open" Explorer Folder of File and show

I just did it and this answer seems ok to me

"how" did you ask ChatGPT ... i would like to try it

---

i got this CODE which seems to do what i want

Code: Select all  Expand view

FUNCTION FileInfo(cPath, cFilename, nItem, cHDR)
/**********************************************/
LOCAL  objFolder
LOCAL  objFolderItem
LOCAL  cFileInfo
LOCAL  cHeaderInfo
Public objShell   := CreateObject("Shell.Application")

  objFolder         := objShell:Namespace(cPath)
  objFolderItem     := objFolder:ParseName(cFilename)
  cFileInfo         := objFolder:GetDetailsOf(objFolderItem, nItem)
  cHeaderInfo       := objFolder:GetDetailsOf(objFolder:Items, nItem)

IF cHDR == 'H'
   RETURN cHeaderInfo
ELSE
   RETURN cFileInfo
ENDIF

RETURN NIL

Code: Select all  Expand view

? 'H-HDR', FileInfo(cPath, aFiles [XX, F_NAME ] , 021, 'H') // TITLE

FOR YY = 1 TO LEN(aMusic_FileInfo) -1
   cTITLE2  := FileInfo(cPath, aFiles [ XX, F_NAME ], aMusic_FileInfo [ YY ], 'F')

Problem :
i need to "know Name" of Property

Code: Select all  Expand view

aMusic_Headers    := {}
AADD(aMusic_Headers, {001, 'Grootte  '} )
AADD(aMusic_Headers, {016, 'Genre    '} )

AADD(aMusic_Headers, {015, 'Year     '} )

AADD(aMusic_Headers, {011, 'Kind     '} )
AADD(aMusic_Headers, {013, 'Contr_art'} )
AADD(aMusic_Headers, {220, 'Composers'} )

but how to get "Name"

[Antonio Linares]

I just asked chatGPT this:

modify this code so it returns all the members of the structure:

and your code

the answer seems fine

Code: Select all  Expand view

#include "hbapi.h"
#include "hbvm.h"
#include "shellapi.h"

HB_FUNC( SHELLEXECUTEINFO )

   sei.fMask = SEE_MASK_NOCLOSEPROCESS;
   sei.hwnd = NULL;
   sei.lpVerb = NULL;
   sei.lpFile = ( LPCTSTR ) hb_parc( 1 );
   sei.lpParameters = ( LPCTSTR ) hb_parc( 2 );
   sei.lpDirectory = ( LPCTSTR ) hb_parc( 3 );
   sei.nShow = SW_SHOW;

hi Antonio,

the answer seems fine

it will not compile on my PC ...

hi,

have try other Way using "Shell.Application" and GetDetailsOf()

Code: Select all  Expand view

FUNCTION GetMetaData(cPath, cFilename)
LOCAL aRet  := {}
LOCAL nItem ,iMax := 333
LOCAL cRet  := ""
LOCAL cRet2 := ""
LOCAL objShell := CreateObject("Shell.Application")

   FOR nItem := 1 TO iMax
      cRet2 := FileInfo(objShell,cPath, cFilename, nItem-1, "H")
      cRet  := FileInfo(objShell,cPath, cFilename, nItem-1, "F")

      IF !EMPTY(cRet2) .and. !EMPTY(cRet)
         AADD(aRet,{TRIM(VAR2CHAR(cRet2)), TRIM(VAR2CHAR(cRet))})
      ENDIF
   NEXT

   objShell := NIL

RETURN aRet

Code: Select all  Expand view

FUNCTION FileInfo(objShell,cPath, cFilename, nItem, cHDR)
LOCAL objFolder
LOCAL objFolderItem
LOCAL cFileInfo
LOCAL cHeaderInfo
LOCAL cRet

   objFolder         := objShell:Namespace(cPath)
   objFolderItem     := objFolder:ParseName(cFilename)
   cFileInfo         := objFolder:GetDetailsOf(objFolderItem, nItem)
   cHeaderInfo       := objFolder:GetDetailsOf(objFolder:Items, nItem)

   IF cHDR == 'H'
      cRet := cHeaderInfo
   ELSE
      cRet := cFileInfo
   ENDIF

RETURN cRet

this now give me a Meta Information like Explorer when add "extra" Column from Popup-Menu

[Antonio Linares]

very good
