Main frame collecting Dialog info?

Can i see more code??

Especially, what is the type of ContactList? Is it really a wxListCtrl? And shouldn't it be a pointer?

BTW: You can't link against headers, you rather mean you included it ;) You link against libraries

Code: Select all

class ContactManagerFrm:public wxFrame
{
...
private:
wxListCtrl *ContactList;
...
}

Code: Select all

void ContactManagerFrm::CreateGUIControls()
{
...
ContactList = new wxListCtrl(ContactListPanel, ID_CONTACTLISTCTRL, wxDefaultPosition, wxSize(200,400), wxLC_LIST | wxLC_SINGLE_SEL);
...
}

Code: Select all

void ContactManagerFrm::dialogClosed()
{
ContactList.DeleteAllItems();
}
Thanks again for your continued support :)

What's your compiler?? The error message it gives doesn't make any sense with what i see. It's weird

ContactList is a pointer, you need to use -> instead of .

Ok, got the

Code: Select all

void ContactManagerFrm::dialogClosed()
{
    ContactList->DeleteAllItems();
}
working as I just posted, but now I have:
error: expected primary-expression before '->' token.
on

Code: Select all

ContactManagerFrm->dialogClosed();
within the dialog. Guess I'm just getting lost here in my mess of code :P

Thanks again :)

error: expected primary-expression before '->' token.
This means syntax is screwed up somewhere... maybe post the full page. Or look if ContactManagerFrm is declared, is a pointer, etc.

BTW i just saw in your snippet that you forgot to put ; after class declaration:

class X
{
...
};

You asked for it... :P
I think its expecting... Well, not quite sure how to word it, I'll see if you say what I'm thinking :)

Thanks again! You deserve more wxAwards than I can give out :D

ContactManagerFrm is a class name, you can't call methods on a class name. You will need a pointer to an ContactManagerFrm instance.

Now remember that because all your errors are about that!
You cannot call methods on a pointer name stored in a string.
You cannot call a method an an ID.
You cannot call a [non-static] method on a class name.

You can only (and only) call a method on an instance with . or on a pointer to an instance using ->


Hope it clarifies things a bit.

And please look again at the sample i provided you at the first page before asking 'how do i get a pointer to ContactManagerFrm?' ;)

Ok, I finished it per your example, but all I get is a program crash when trying to add a contact!

It may be that it's been a while since I've looked at it, but I just can't seem to figure out why it crashes. It might be helpful in noting that even if I'm not just updating the listctrl, it always crashes.

Here are the files if anybody could look at them.

Thanks!

If you use a debugger, where does it crash?

And perhaps you could give at least an hint of what parts of these several files are concerned by this issue... help others help you, dropping a big bunch of code and saying 'please debug this' is not a good way to get answers

FYI - you call a method on 'MainProgramFrame' but you never seem to give a value to it... check my sample again and learn C++... using a pointer without giving a value to it first is plain stupid error, you didn't do the tests i asked you to do... damn, help yourself!
