Float under C, there there The 4 byte large and the 8 byte large.

with whom smaller must You with Single/double transfiguring (see in the Help).

Perhaps writes Sebastian us Yes time one Tutorial to Creation of C-DLLs - with Übergabe/Return all Profanwerte. then would everything moreover on one stain.

PS: Yes, I can me present, I you slow langweile ...

your ask are still always very interestingly...

Wozu must The function really CALLBACK his? Do you have it times without these indicated attempts?

Best wishes

Übergib simply a Zeiger on a Speicherbereich. in the can you as much as you want Bytes Save.

Hi,

XProfan expects as Return Value of external functions always values with of/ one Size of 4 byte, means in the Grunde Longs. naturally can in the DLL simply a C/C++ float give back and then in XProfan with @double() transfiguring, means to that example:

C++:
Compile Mark Separation

float WINAPI Mean(long l1, long l2) { return static_cast<float>((l1+l2)/2); }

XProfan:
Compile Mark Separation

print Wert = ,@Double(Mean(3,2))

to Return of C/C++ doubles, The Yes a wide of 8 byte having, is Franks suggestion with the area very correctly.. for a individual worth could the then so looks:

C++:
Compile Mark Separation

long WINAPI Mean(long l1, long l2, double *pRet)

{

    *pRet = static_cast<double>((l1+l2)/2);
    return 0;

}

XProfan:
Compile Mark Separation

dim ret#,8
Mean(2,3,ret#)
print worth = ,@Float(ret#)
dispose ret#

MfG

Hmm... since of/ one hour attempt I now the to that walk To bring. first wished I The DLL Profan Call. there But The Funktuonen Float() and double() not gives, Have I it time with String$() attempts, be but on The nose fallen.
then Have I me virtual, that it eh sinnvoller would, on The DLL C++ access. Okay, geschafft Have I, that I DLLs mithilfe of LoadLibrary To loading and then with ... naja, schaut you simply whom code on :
Compile Mark Separation

#include <iostream>
#include <windows.h>
using namespace std;
int main()

{

    HMODULE dll;
    dll= LoadLibrary(dll.dll);

    if (dll != NULL)

        {

            typedef int (*DLLFUNC)(int);
            DLLFUNC funk = (DLLFUNC)GetProcAddress(dll, funk);

            if (funk)

                {

                    cout << funk(42);

                }

            }

            FreeLibrary(dll);
            system(PAUSE);
            return EXIT_SUCCESS;

nt color=#0000FF>}

in the DLL dll.dll (

) is solely a function, The funk is and a Int-Parameter has, and as Return Value again this Parameter zurückgibt

.

loading can I The DLL, funktionnieren tuts apparently too. only a double or float as Return Value funktionniert not. ...

... means again the altbekannte trouble ... ajjj ...
Well, for today langts me ... Have Yes finally today already one 3 - stüniges Deutschaufsatzschreiben behind me ...

If well not so tricky would ....

Ah, I had overlooking, that You with Profan² 6.6 work - there there @double(), @Single() and @Float() not yet... for the first both find You substitute-Procedures in my middle-aged DirectX-Codes - are though something uncomfortably in the management

with the others trouble would it helpful, if you time whom Source the function funk post could. should these a Fließkommazahl give back? if so, lying the Error evtl. simply in the row

typedef int (*DLLFUNC)(int);

These definiert finally DLLFUNC as Zeiger on a function, The a int as argument expects and a int zurückgibt. foreseen of it missing too the WINAPI or. __stdcall around the Aufrufkonvention anzugeben...

Ah, thanks

I habs the now so far geschafft, that it funktionniert, lying really somehow on whom not suitable ints

thanks so far.
Ergebniss becomes posted, if verwertbar
