Yet another DllCall() problem

6 posts in this topic

;) 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

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



Func _BluetoothFindFirstDevice()
$tBLUETOOTH_DEVICE_SEARCH_PARAMS = DllStructCreate('DWORD;BOOL;BOOL;BOOL;BOOL;BOOL;BYTE;HANDLE')

      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

Please help?
      Thank you in advance!

      Hi
      here's another UDF for the serial port. It is very similar to CommAPI using kernel32.dll, but all code is packed into a single file without any dependencies, not even using WinAPI.au3. It differs from existing UDF that it doesn't allow a timeout when reading, instead it always returns immediately, either with the requested amount ob bytes read or with a failure status. And of course there is a function provided to query the amount of available bytes in the receive buffer. The reason behind this design decision: You can do 1000 other things in the main loop while checking from time to time if enough data bytes arrived. There's no point to block the program waiting for the serial port.
      It is currently a work-in-progress, as I didn't test all functions yet. The code was developed and tested on Windows 7 64 bit.  The ComUDF-Tests.au3 shows some tests and basic usage of the UDF. Maybe there's no reason to use this UDF, given the existence of the others UDFs, but I did it to get to know DllCall better - I use structs no only to pass but also to get data back (I don't use the array returned by DllCall to read that data, unless required). You're welcome to test it on older and newer Windows versions.
      Here's a list of the implemented functions:
      ; _ComListPorts ; _ComOpenPort ; _ComSetTimeouts ; _ComClosePort ; ; _ComSetBreak ; _ComClearBreak ; _ComGetInputcount ; _ComGetOutputcount ; _ComClearOutputBuffer ; _ComClearInputBuffer ; ; _ComSendByte ; _ComReadByte ; _ComSendBinary ; _ComReadBinary ; ; _ComSendChar ; _ComReadChar ; _ComSendCharArray ; _ComReadCharArray ; _ComSendString ; _ComReadString ; ; __ComClearCommError ; __PurgeComm Maze

      So I had this Idea of creating a tooltip which shows me my ping.
      That itself was made quickly and I thought too add a couple features.
      I want the tooltip background to be a different color depending on the ping. (good ping is green, medium ping is yellow,...)
      So how do I color in a tooltip? google brought me to this: 
       
      where in the comments I found this:
      $s = "LOW" ToolTip($s, 0, 0, "Battery Information");, $icon) $H_TOOLTIP1 = WinGetHandle($s) DllCall("UxTheme.dll", "int", "SetWindowTheme", "hwnd", $H_TOOLTIP1, "wstr", "", "wstr", "") DllCall("user32.dll", "int", "SendMessage", "hwnd", $H_TOOLTIP1, "int", 1043, "int", 2552550, "int", 0) Sleep(1000) Which I then used in my code with different color codes... Trial and Error brought me these that I wanted to use:
       
      The Problem is if I loop through my code it only sets the color for the 1st loop and then sticks to it.
      The real problem is tho that I don't exactly understand the dllcalls... And I guess that's why it isn't working
      So if someone would be so awesome to explain to me how they work, or at least can give me a list of these parameters then I would really appreciate that and learn something new
      Obviously a solution to my problem is awesome aswell ^^
      I run this under Windows 8.1
      There is my code in a paste.

      Hello Guys,
      once aggain I need your help on a DLL Topic
      I need to pass arguments to my function via a structure, because I am limited to only one argument that can be passed.
      But I don't think that thats so important.
      So here's my approach:
      C++ Code (just the important part):
      extern "C" { struct ParamStruct { const char* test1; const char* test2; const char* test3; int size; }; int testFunc(struct ParamStruct * params) { return params->size; } } And thats how I try to call the function using Autoit:
      Local $struct = "struct;char shapefile[128];char output[128];char filename[128];int size;endstruct" Local $tTest = DllStructCreate($struct) DllStructSetData($tTest, "test1", "Bla") DllStructSetData($tTest, "test2", "BlaBla") DllStructSetData($tTest, "test3", "BlaBlaBla") DllStructSetData($tTest, "size", 40) $dll = DLLOpen("myDLL.dll") $ret = DllCall($dll, "int:cdecl", "testFunc", "STRUCT*", DllStructGetPtr($tTest)) MsgBox(0, 0, $ret[0]) DllClose($dll) Just for testing I want the function to just return the integer value in the struct.
      But this aint working. I tested many things, but still I'm not able to get it running. I even don't know if the mistakes are in the C++ code or the Autoit code or both .. I'm not that skilled at C++ and also not that skilled at Autoit DLLCalls :-/
      I would really appreciate some help!
      Kind regards,
      leo
