  1. When I use DllStructCreate() to reserve a chunk of memory I would like to know if I can rely on that memory being initialized to zero. Experience suggests that it is, but I have been searching to try and find a definitive statement anywhere that this is the case. I apologise if I have missed somewhere. Part of the reason for this question is so that my next search (after my personal memory has dimmed) should yield a link to this post, hopefully with an answer. A number of DLLs I use have structs where a few parts have to be explicitly set and other parts are reserved with the instruction
  2. 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.
  3. 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 $str
  4. Hi, I'm blocked on a strange issue concerning the use of '_WinAPI_ReadProcessMemory' to retrieve one 'String' between 2 cooperating applications based on the IPC method using a private 'Windows Message' handler (thanks to '_WinAPI_RegisterWindowMessage'). Let's me explain what happens: 1) - From a small GUI 'ipc-sender' application, the user can type any string (like 'abcde') and click a 'Send Data' button to exchange this info with another small 'ipc-receiver' application. the coding is done in such way ( '_DumpStruct()' method) that a trace of the data sent is dumped in an edi
  5. I am trying to serialize all the autoit variable by >msgpack, so that I can used it in ZeroRPC (language-agnostic remote procedure call over internet). Int, string, binary are easy, but DllStruct is not. Before variable serialization become build-in function (I hope so), I have to find out my own way. Here is my attempt to guess the setup string. I am not sure did I deal with all the align and struct/endstruct correctly, please let me know if there is any bug. The output may not be the same with the original string, it is not bug. Test() Func Test() Local $Struct $Struc
  6. _DLLStructDisplay While working on debugging a project a while back, I was looking for better ways to debug the code. And voila, here it is. Anyway, this function displays the contents of your DLLStruct's in a ListView format (placing the items in an array and utilizing _ArrayDisplay). IMPORTANT: You must supply the string EXACTLY as it was used to set up the structure (although you can add descriptions after the datatypes if they aren't already there). The string requirement might seem like one more extra step, but without it the function wouldn't work (and you're debugging would be much
  7. 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_PARA
  8. Hello voluntary posters I got a question about autoit that I've been unable to find a straight yes or no answer on in the documentation I've read. Well I've been learning C++ lately and I've found that structures are a big deal and very ways of storing variables. Now I can finally understand why in all the advanced programming in autoit they include so many 'Dllcreatestruct' type commands. My question is that, how is it possible to create functions that pass that data created from the dllcreatestruct. Isn't it good programming technique to create as few global variables as possible?
