Expected ; or =(cannot specify constructor arguments in declaration)

[senthurbalan]

hi,
I've been trying to work on NXopen(NX is a cad software). I'm using c# codes for that. For opening a new file in NX this is the syntax which has been given

int UF_PART_new
(

const char * part_name,
int units,
tag_t * part

)

This is the code I made in Visual Studio

//TODO: Add your application code here
const char *part_name=@"D:\\rahul\\assignments\\extrude1.prt";
tag_t part= NULL_TAG;
int units=1;
int UF_PART_new(part_name,units,&part)

Now I'm getting errors like

Expected ; or =(cannot specify constructor arguments in declaration)
; expected

both are on "int UF_PART_new(part_name,units,&part)" line. Please someone help me on this.

You say you're using C#, but the code you have is C++ - unless you're intending to use unsafe C# code, which usually isn't necessary.
The C# code would be:

string part_name=@"D:\\rahul\\assignments\\extrude1.prt";
 tag_t part= NULL_TAG;
 int units=1;
 int test = UF_PART_new(part_name, units, part);

For C++ code or unsafe C# code, I think all you're missing is that you either need:

int test = UF_PART_new(part_name, units, &part); //use return value

or:

UF_PART_new(part_name, units, &part); //ignore return value

Hiya

Thanks for that, but it didn't work either.

I'm completely novice to c++ or c# programming, but I can understand the concepts, the only hurdle is "which element needs to used where" concepts.

Can you pls explain how did you tell that my codes are in c++ and not in c#(I was thinking them to be c# codes). And what do you mean by unsafe c# codes ?

If you can then kindly let me know whether I can be in touch with you through personal messages so that I can solve my doubts then and there.
