Your 'Fetcher' class doesn't know about 'mytext' since it is a member of 'eBibleMainWindow'.
zeos (29)
so how i can resolve it ???

It really depends largely on how your overall design is set up. But, to give a solution: you could consider changing the member function 'fetch' to take a parameter that is a reference or pointer to the 'eTextInputField' mytext object. I prefer using a reference, but since in your 'eBibleMainWindow' class the 'eTextInputField' member is a pointer, go with that:

 
 
void Fetcher::fetch(eTextInputField* const obj) const;


That's one way to do it. Let's see if someone else has a better way to do it.

You have some syntax errors and your the two signatures of fetch() don't match. One has no parameters and the other has one.
sadavied (71)
You have to change the definition of the 'fetch' function in the class definition as well.

You will have to change the way you call the fetch function anywhere in your program. You now have to pass a eTextInputField pointer.

void eBibleMainWindow::Wconnect()
...
thefetcher.fetch(mytext);
...


Also, in the fetch function you will need to change this line:
 
 
code = mytext->getText();

You will need to change 'mytext' to whatever you named the formal parameter.

dont' work !!!
sadavied (71)
As in it still won't compile, or it doesn't work at runtime? If it won't compile, let's see the compile errors.
zeos (29)
please can you add your reponse in my programme i can't resolve by myself
zeos (29)
the problem still exit i will be crazy ... please EXPERT !!!

what i need with this programme is /

when i type the code (eTextInputField *mytext)
the code is added to the url and it connect to the site for verifie the code

code = mytext->getText();
url = "http://www.host.com/activate.php/?code="+code;

Post your entire Fetcher class along with the fetch function code as you have it and are trying to compile. I don't think you have made the changes that I said were necessary.
shadowvillian (135)
Why don't you just use inheritance? Instead of defining fetchers inside main window just have main window inherit fetchers members. Or an I just dumb and your already doing that.

I suppose inheriting from Fetcher would work, but I don't think that would be quite right. Inheritance implies an 'is a...' relationship. I'm not really seeing a 'eBibleMainWindow' as a Fetcher.

Update - I changed the code slightly in my previous posts. I was incorrect in making the parameter a 'const eTextInputField*'. It should have been a 'eTextInputField* const' so that the object can be modified within the function body.

So true. But thats just what came to mind at first.
