Declaration and calling of a dll in eVB

TheMSsForum.com: The Microsoft Software Forum

Hello,


I must use a custom dll in my eVB project. I have to call 2 functions of

this dll. So I have two questions.


1) How can I call GetDllVersion with eVB (declaration + calling of

function)??


Here is the declaration of the function:


char * GetDllVersion(void); 'c declaration


This function must return the dll version (for example :1.1), my problem is

the return type of the dll.


2) How can I call the GetToto function in eVB (declaration + calling of

function)??


Here is the declaration of the function:


int GetToto(typeStruc varToto, int var1,int var2) with the following

structure:


typedef struct

{ char char1;

int int1;

}typeStruc;


Thanks a lot for your answer.

Ok for the stucture. I will try...

But for the *char return type, do you have an idea because when I call this
function in eVB, with this declaration :

public declare GetDllVersion lib "MyLib.dll" () as string

This function must return a string, like "1.1", but returns "_1r".

There is a problem conversion ANSI-Unicode ?
