Hello, I am trying to write very basic script to use COM object. It is a specific object allowed to communication with software on the industrial controller. I can create reference to a COM object by function ObjCreate. Thanks to ObjectName function I can read all information about object. Problem is that, I can trigger (only) one method of this object, named Disconnect(). When I want to use the other method instead of Disconnect(), for example, ReadValueN I have problem with arguments for this method. I tryed many variants, combinations, without positive result. My error monitoring function (for COM errors) reports: "Bad variable types" or "Type mismath". I studied many examples, many documentations but I have no idea how it should be. Below is description for method, data etc based on OLE/ COM Object Viewer. long ReadValueN(
[in] long TARGET_id,
[in] PARAM_DEF* pParamDef,
[out] BUFFER* pResBuffer);typedef struct tagPARAM_DEF{
unsigned char Param1;
unsigned char Param2;
unsigned char Param3;
unsigned char ParamT[8];
short Number;
unsigned char ValueF;
unsigned char ValueD;
} PARAM_DEF;
typedef struct tagBUFFER{
unsigned char BuffA1;
unsigned char BuffA2;
unsigned char BuffA3;
unsigned char BuffTable[256];
} BUFFER;$structParamDef = DllStructCreate("byte; byte; byte; byte[8]; short; byte; byte")
$structBuffer = DllStructCreate("byte; byte; byte; byte[256]")
$response = $myObject.ReadValueN(0, DllStructGetPtr($structParamDef), DllStructGetPtr($structBuffer))
;$response = $myObject.Disconnect() ; is workingCould someone write me what is wrong and how it should be? And especially - why? thanks in advanced
