Yet another DllCall() problem

Recommended Posts

stormbreaker

;) Hello everyone. Yet I face another DllCall (maybe DllStruct?) problem here, could someone please guide me, here's the code:

#include 
Global Const $hDllBthProps = DllOpen("bthprops.cpl")

Func _BluetoothFindFirstDevice()
$tBLUETOOTH_DEVICE_SEARCH_PARAMS = DllStructCreate('DWORD;BOOL;BOOL;BOOL;BOOL;BOOL;BYTE;HANDLE')
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 1 , DllStructGetSize($tBLUETOOTH_DEVICE_SEARCH_PARAMS))
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 2 , False)
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 3 , False)
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 4 , True)
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 5 , False)
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 6 , True)
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 7 , 30)
DllStructSetData($tBLUETOOTH_DEVICE_SEARCH_PARAMS, 8 , Null)
$SYSTEMTIME=DllStructCreate("ushort wYear;ushort wMonth;ushort wDayOfWeek;ushort wDay;ushort wHour;ushort wMinute;ushort wSecond;ushort wMilliseconds")
DllCall("Kernel32.dll","none","GetSystemTime","ptr",DllStructGetPtr($SYSTEMTIME))
$tBLUETOOTH_DEVICE_INFO = DllStructCreate('DWORD;ULONG;ULONG;BOOL;BOOL;BOOL;ptr;ptr;WCHAR')
DllStructSetData($tBLUETOOTH_DEVICE_INFO,1,DllStructGetSize($tBLUETOOTH_DEVICE_INFO))
DllStructSetData($tBLUETOOTH_DEVICE_INFO,7,DllStructGetPtr($SYSTEMTIME))
DllStructSetData($tBLUETOOTH_DEVICE_INFO,8,DllStructGetPtr($SYSTEMTIME))
$RESULT = DllCall($hDllBthProps, "handle", "BluetoothFindFirstDevice", "struct*", $tBLUETOOTH_DEVICE_SEARCH_PARAMS, "struct*", $tBLUETOOTH_DEVICE_INFO)
msgbox(64, "", 'Result: ' & $RESULT[0] & @crlf & 'WinAPI Error: ' & _WinAPI_GetLastErrorMessage() & @crlf & 'Error: ' & @error)
EndFunc

_BluetoothFindFirstDevice()

The function doesn't seem to work, even though I have enabled and paired up my laptop and computer's bluetooth. :)

Thanks.

JohnOne JohnOne JohnOne, bthprops.cpl is itself a dll that can be 'executed' by rundll32.exe, I indeed tried calling the DLL but couldn't. If you see my signature for Bluetooth Detector Script, you will find that I am indeed right in my approach.

MKISH.

try to change the BLUETOOTH_DEVICE_INFO structure...

#include

      So first things first the example in the help file for _WinApi_Enum_Windows has an error
      ;_ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, Default, "#|Handle|Class|Title|Text|Process") Should Be _ArrayDisplay($aResult, "_WinAPI_EnumWindows", Default, Default, Default, "Handle|Class|Title|Text|Process") Next is a bit of helpful info on LPCSTR in a callback function it needs  to be passed as a PTR
      DllCallbackRegister($sFUNCT, $sRETURN, "ptr") Finally on to my question
      I'd want to call EnumPropsEX and pass a string through lparam + append to it rather than declaring anything globally
      I can Come up with two ways to do this The second it a lot more code but possibly safer but the first way I think Should do
      1. From a bit of testing It seems AutoIt won't overflow a DllStruct?
      2. Are strings passed through DLL call guaranteed to be 'an ANSI string (a minimum of 65536 chars is allocated)' as the Helpfile clearly states?

      At least illogical to me!
      The following script is based on a script jchd wrote. I have changed it so it returns a tag rather than writing the element types and values to the Console. The tag and the values set in the structure are those he used.
      As is, it returns "char;". It should return "char[3]; ...'. With changes in the diagnostic code, I have seem it return "char[3];", but it should return the whole tag.
      I am aware that the script will not differentiate, for example, between an int and a long: it works from the type of what DllStructGetData returns, and calls it an int.
      I am concerned that there may be a memory leak due to a DLLStruct* call, because the code, with minor variations, produces different results.
      I have instrumented it liberally, but @error is 0 everywhere.
      Clues will be most welcome!
      Local $tag = "char a[3];handle b[3];uint c[35];byte d[128];wchar e[190000]; double f[3];int64 g[3];" & _ "char h[3];float i;double j;byte k;ubyte l;short m;ushort n;int o;uint p;char q" Local $struct = DllStructCreate($tag) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 1, 'sos') If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 2, Ptr(123456789)) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 3, 8, 1) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 3, 0x87654321, 2) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 3, 256, 5) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 4, Binary('sos')) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 5, 'gno' & @CRLF & 'ji' & @TAB & 'o') If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 6, 3.1415926, 2) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 7, 17, 1) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 7, -1, 2) DllStructSetData($struct, 8, 'end') If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 9, 2.7182818284590452353602874713527) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 10, 2.7182818284590452353602874713527) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 11, 107) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 12, -108) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 13, 109) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 14, 110) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 15, 111) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($struct, 16, 112) If @error Then MsgBox(0,@ScriptLineNumber,@error) _cDebug_DetectStructElements($struct) Func _cDebug_DetectStructElements($tStruct) Local $retTag Local $len = DllStructGetSize($tStruct) Local $ptr = DllStructGetPtr($tStruct) Local $nbElem = 1, $idx, $incr, $data, $type, $oldvalue, $readvalue, $elem $g_CDebug_sStructElementTypes = '' While 1 $data = DllStructGetData($tStruct, $nbElem) If @error And @error<>2 Then MsgBox(0,@ScriptLineNumber,@error) If @error = 2 Then ExitLoop ; if element out of range or unknown $type = VarGetType($data) $idx = 1 $incr = 0 ; determine max index of element While 1 DllStructGetData($tStruct, $nbElem, 2 * $idx) If @error And @error<>3 Then MsgBox(0,@ScriptLineNumber,@error) If @error = 3 Then ExitLoop $incr = $idx $idx *= 2 WEnd ; index is in [$idx, (2 * $idx) - 1] $idx += $incr Do DllStructGetData($tStruct, $nbElem, $idx) If @error And @error<>3 Then MsgBox(0,@ScriptLineNumber,@error) If @error = 3 Then ; if element is out of range ; approach is asymetric (upper bound is too big) $idx -= ($incr = 1) ? 1 : $incr / 2 Else $idx += Int($incr / 2) EndIf $incr = Int($incr / 2) Until $incr = 0 Switch $type Case "Int32", "Int64" $data = DllStructGetData($tStruct, $nbElem, 1) If @error Then MsgBox(0,@ScriptLineNumber,@error) DllStructSetData($tStruct, $nbElem, 0x7777666655554433, 1) $readvalue = DllStructGetData($tStruct, $nbElem, 1) If @error Then MsgBox(0,@ScriptLineNumber,@error) Switch $readvalue Case 0x7777666655554433 $elem = "int64" ; alias: uint64 ; alias: int_ptr(x64), long_ptr(x64), lresult(x64), lparam(x64) ; alias: uint_ptr(x64), ulong_ptr(x64), dword_ptr(x64), wparam(x64) Case 0x55554433 DllStructSetData($tStruct, $nbElem, 0x88887777, 1) If @error Then MsgBox(0,@ScriptLineNumber,@error) $readvalue = DllStructGetData($tStruct, $nbElem, 1) If @error Then MsgBox(0,@ScriptLineNumber,@error) $elem = ($readvalue > 0 ?

      Hello,
       
      I'm trying to figure out how to add attributes to a Credentials Store.  I have been using it to store Creds and I was using the Comments to store some limited data but I'd really like to start using the 64 possible Attributes so I don't need to use the Registry to store misc information my script needs.
       
      I have been trying to figure this our for a few days now and I'm able to create the structure, but it fails with Invalid Parameter when trying to add the item to the store.
       
      Any ideas or pointers to where to get some further information on this?
      Thanks,
      Mike

      I've been working with the Windows Credentials store to store credentials for lots of RDP connections.  I'm also using this code in other scripts to store and retrieve "legacy" credentials for my scripts that have a Save Password checkbox.
      All goes well, until someone requests a button to display a list of all saved credentials.  I found the CredEnumerate call and it looks like it's working but the Target and UserName field that I want is stored inside an array of pointers and I can't figure out how to get data from inside that.  I found a post from 2009 that talks about this, but there was never a solution.
       
      Below are my functions put into an example script.  the _Credentials_Enumerate() is where i'm having problems.   Anybody have some ideas?
      Thanks,
      Mike
