convert eVC++ prototype to VB.NET

[Eric BOUXIROT]

hi,

i must convert all of these eVC++ prototypes to use with VB.NET....

DLLEXPORT long F_BDO_MessageBo xOK(char *IN_title, char *IN_msg );
DLLEXPORT long F_BDO_MessageBo xOUINON(char *IN_title, char *IN_msg );
DLLEXPORT long F_BDO_CalculAXp lusB(short int *IN_Tab_entree ,int IN_taille
,
double *OUT_Tab_sortie _freq ,
double *OUT_Tab_sortie , double IN_A,
double IN_B, double IN_Te, double OUT_Elt_max[2],
double OUT_Elt_min[2] );
DLLEXPORT long F_BDO_determine _A_et_B(int IN_Point1[2] ,int IN_Point2[2] ,
double *OUT_A, double *OUT_B );
DLLEXPORT long F_BDO_trouve_ma ximum(short int *IN_Tab_entree ,int IN_taille
,
short int IN_seuil, double IN_A,
double IN_B, int *OUT_n_max,
double *OUT_y_max );
DLLEXPORT long F_BDO_trouve_ma x_et_min(double *IN_Tab_entree ,int IN_taille
,
double *OUT_max, double *OUT_min);
DLLEXPORT long F_BDO_conv_line aire_dbl(double *IN_Tab_entree, int IN_taille,
double *OUT_Tab_sortie );
DLLEXPORT long F_BDO_conv_dbl_ dba(double *IN_Tab_entree, int IN_taille,
double *OUT_Tab_sortie );
DLLEXPORT long F_BDO_conv_dbl_ dba_bf(double *IN_Tab_entree, double
*IN_Tab_freq,
int IN_taille,doubl e *OUT_Tab_sortie );
DLLEXPORT long F_BDO_trouver_i ndice_harmoniqu e_roue(double
*IN_Tab_entree, double *IN_Tab_freq,
int IN_taille,doubl e freq_theorique,
double seuil_freq,doub le seuil_ampl,
unsigned short int *OUT_Tab_ind_ha rmonique);
DLLEXPORT char F_BDO_init(void );
DLLEXPORT void F_BDO_close(voi d);
DLLEXPORT char F_BDO_start(voi d);
DLLEXPORT char F_BDO_stop(void );
DLLEXPORT char F_BDO_getSample (char *pBuf,long *cbDone);

what rules i can apply to correctly convert datas type parameters ?

thank a lot ...

Re: convert eVC++ prototype to VB.NET

Almost straightforward .

The only catches here are:
long becomes Int32 (or Integer)
char* needs to be passed as Byte() and you will have to convert strings
manually by using Encoding.ASCII. GetBytes(myStri ng + Chr(0))
double* is Double()
short int * is Int16()
double cannot be passed down at all. you can only pass it ByRef and your c++
function will need to be modified or a wrapper written around it.
char as return value stays Char (or Byte can be used)

Paul Yao has a tool for you to look at.
