can't convert C# signature to MC++

[Boni]

Please help C#
how to convert this C# to MC++
public void Execute(object application, int hwndOwner, ref object[]
contextParams, ref object[] customParams, ref EnvDTE.wizardResult retval) ;

I tried

void Execute(System::Object* application, int hwndOwner,
System::Object*&contextParamss, System::Object*& customParams,
EnvDTE::wizardResult &retval)

void Execute(System::Object* application, int hwndOwner, System::Object&
contextParams[], System::Object& customParams[], EnvDTE::wizardResult
&retval)

and some others but can find a right one.

Please how can I get a reference to the array?

Thanks so much,

Boni

Boni,

how to convert this C# to MC++
public void Execute(object application, int hwndOwner, ref object[]
contextParams, ref object[] customParams, ref EnvDTE.wizardResult retval)
;

Try
public:
void Execute (
Object* application, int hwndOwner,
Object* (&customParams) __gc[],
EnvDTE::wizardResult& retval
);

Hope I got that right ;)

Hi Tomas,
Seems to be still wrong. The error is:

error C2259: 'cPxy' : cannot instantiate abstract class

due to following members:

'void cPxy::Execute(System::Object __gc *,int,System::Object __gc *(__gc *)
__gc[],System::Object __gc *(__gc *) __gc[],EnvDTE::wizardResult __gc *)' :
pure virtual function was not defined

cProxy.cpp(0) : see declaration of 'cPxy::Execute'

But most strange is, that is I take the signature from the error (just
copy/paste) the error still there!!!! I am trying to reload IDTWizard with
MC++.

Do you have more suggestrions, please!!

The following seems to compile for me:

public __gc class MyWizard : public EnvDTE::IDTWizard
{
public:
virtual void Execute (
Object* Application,
int hwndOwner,
Object* (*ContextParams) __gc[],
EnvDTE::wizardResult __gc* retval
)
{
// ...
}
};

Thanks, you are grea! The following compiles (as you suggested!!)
Thanks so much!!!!!
BTW where is the exact difference between
Object* (*ContextParams) __gc[]

and

Object * __gc (*ContextParams) __gc[]

?

virtual void Execute (

Object* Application,

int hwndOwner,

Object* (*ContextParams) __gc[],

Object* (*arg3) __gc[],

EnvDTE::wizardResult __gc* retval

);

You mean Object __gc* (*ContextParams) __gc[] ?

If so, then nothing, they are equivalent. However, I've seen some cases
where in complex declarations like this the compiler used to get confused so
specifying explicitly the __gc-ness of a pointer or array declaration was
useful.

Dear Thomas,
thank you. I just experienced one more problem with __gc-ness.
MethodInfo->Invoke, need as a second argument a pointer to the managed
parameter array, isnt it?
So how can I create this array from the actual parameters, when all
parameters have different type.
Do I need Object **?
Please help me.
void MyClass::Execute ( Object* Application, int hwndOwner, Object*
(*ContextParams) __gc[], Object* (*ContextParams8) __gc[],
EnvDTE::wizardResult __gc* retval){

Object __gc* (*_arr) __gc[] =new (Object*)[5];

_arr[0]=&Application;

_arr[1]=&hwndOwner;

_arr[2]=&ContextParams;

_arr[3]=&ContextParams8;

_arr[4]=&retval;

m_Execute->Invoke(m_Instance, _arr); //m_Execute is MethodInfo

};

You need a __gc array of Object*, which is different:

Object* arr __gc[] = new Object*[5];
arr[0] = ...

Notice that if you're going to be putting value types into this, you'll need
boxing.

Hi Tomas,
Thank you. I also needed reinterpret_cast<Object*>(...).
I can't wait until I am in the state when I can run this dll :)))
In any case it compiles now!!!
Thank you sooo much.
With best regards,
Boni
