Set a breakpoint at the position where the function is called and then use the debugger command "step into".

Hi jhwurmbach ,
The main problem is the I can not predict which function is called. So where should I add break point.
Thanks in Advance

 Why so ?

Well, if you don't know your software !!!
Read the code, put break points where you think they should be, if they don't trigger, put them somewhere else. You should know at least what your software do!

Why not?
You have the statement where the decision occurs. There you put the breakpoint.

only one way.
add break points at the start of all the functions and see

Is your application multithreaded ?

hi im trying to get the confgui to work in Jxta-C
but when i try to build the project i get a error saying
error C2664: 'jxta_advertisement_get_string' : cannot convert parameter 2 from 'const char [5]' to 'Jxta_index *'
from this line
peername = jxta_advertisement_get_string((Jxta_advertisement*)pa,"Name");
i beleive that jxta_index comes from another file which constructs it as below
struct _jxta_index {
JXTA_OBJECT_HANDLE;
JString *element;
JString *attribute;
char *parm;
Jxta_object *range;
};
can anybody tell me how i should change the jxta_advertisement_get_string line so that it will work
thanks

Give it the adress of a Jxta_index as second parameter, instead of the char[5] "Name".
Just like the error-message says.

hi sorry but im not sure how i would find the address of Jxta_index could you please explain
|
|
|
|
|
To get the address of a variable, you use the so called "address-of"-operator: a <big>&</big> prefixed to the variable name.

thanks still doest work tho if i use &Name i get a undeclared identifier error if i use &Jxta_index i get a error saying illegal use of this type as an expression

I have really no idea how jxta works, but the compiler clearly says it doesn't want a string literal here, but the address of a variable of the type Jxta_index.
Whatever that is. And whereever you get that from.
Does the documentation state the call should take a string as the second parameter? Then David Crow could be right:
Exchange "Name" with _T("Name").
Wrapping with _T("") should become a habit with string literals.
This way, in Unicode, the literals are unicode strings, in non-unicode they are char*.

sorry i have not been able to find any docunentation regarding the jxta_advertisement_get_string method or Jxta_index
|
|
|

How did you come to code the function call the way you did?
Fact is, the function takes a pointer to a Jxta_index. Not a string.

I don't want to sound harsh but I really think you should learn the C++ basics first. When I look at your replies, it seems that you don't really know what you are talking about.
Your function expects to receive a pointer to a specific structure (Jxta_index) so, why are you passing a string instead ?
You should fill a structure like that and pass its address to the function. And honnestly, I don't think anybody here will be able to help you more than that (because probably not a lot of people here know what jxta is).
pds8475 wrote: if i use &Jxta_index i get a error saying illegal use of this type as an expression
Once again, this is basic C++: Jxta_index is a structure declaration, so as your compiler says you cannot use it as an expression. You need to create an instance of it:
Jxta_index myStruct;
Then fill it appropriately (should be documented somewhere I suppose) and then pass its address to your function.

just to make it clear i didnt write this a developer at sun did
|
|
|
|

Yes, I know that you didn't write these functions. But honnestly this is really basic C++: this is just a function that accepts a pointer to a structure as parameter. How to use it should be explained somwhere in a documentation.

hi there is very little documentation on Jxta-c and after searching the net i can only find 3 references to Jxta_index and they are talking about other classes that use Jxta_index

There is a complete API-Doc[^] (automagically made from the code by doxygen). It is properly linked at the Projects website.
I must admit that the documentation seems to be wrong for jxta_advertisement_get_string(). The brief description and the "Parameters" section seem to contradict.
Probably the Parameters-comment has not been updated - thebane of doxygen-like documentation.
char* jxta_advertisement_get_string ( Jxta_advertisement * ad,
Jxta_index * ji
)
Many fields of an advertisement struct can be represented as a character string, which may be obtained by this function.
Parameters:
Jxta_advertisement * ad
char * key for advertisement field desired
Returns:
char * representation of value corresponding to key.
Warning:
Returns a copy that must be freed.

This is usually a Unicode vs. ANSI error. Try putting an L in front of the string literal.
[edit]
Now that I've gone back and read your post, my suggestion was way off. Sorry about that.

hi thanks for that but now i get a error message saying cannot convert parameter 2 from 'const wchar_t [5]' to 'Jxta_index *

It must be something else then. Rather than code something up to find out for sure, I was just taking a stab at something common.
