there are many possibilities for this error, but the most common ones are these:
1. the function is not included in the lib file
2. the declaration of the function does not match with the definison by the linker
Don't try it, just do it!

nopes still no luck in getting it working 
anyways thanks for your help guys...
anyways downloaded the library and code from
if anybody can download it from http://iaxclient.sourceforge.net/iaxcomm/iaxcomm-win-20040228.zip
and give me some tips of using it in Visual C++ i will be greatfull..
its basically a open source softphone library using IAX protocol..
the library compiles ok...i just cant seem to be able to use the library in my other projects.
Thanks

might be also that .lib is not included  check lib path.

when he gave the command of using the lib, then the linker gives an error message if it doesnt find the lib.

How to map array of CButtons to button resources on Dialog form?
|
|
|
|

Have you looked at CMap?

I looked in MSDN, but I'm not quite sure if I know how to use it in this case.

"It" being MSDN or the CMap class?

It being CMap. Sorry for misunderstanding.
|
|

Something like:
CMap<int,int,CButton*,CButton*> mapButtons;
mapButtons.SetAt(123, &m_btn1);
mapButtons.SetAt(456, &m_btn2);
mapButtons.SetAt(789, &m_btn3);
CButton *btn;
BOOL bFound;
bFound = mapButtons.Lookup(123, btn);
bFound = mapButtons.Lookup(234, btn); Think of a map as a cross-reference.

Thanks for your help, but shoudn't DoDataExchange() be in some way involved in this?
I have an array CButton btns[10] that need to be 'connected' to 10 buttons on a dialog form. If I use ClassWizard (Member Variables) I can map each button with a single CButton variable, but it doesn't allow me to use btns[0], for example, as a name of a variable.
|

You can bypass ClassWizard and code assignments in DoDataExchange by hand. Just leave your 'manual' assignments out of the special code section delimited by
//{{AFX_DATA_MAP(<dialogclassname>)
//}}AFX_DATA_MAP
I do this all the time for custom DDV routines not built into ClassWizard or to make special assignment like you need.
You can try:
//{{AFX_DATA_MAP(<dialogclassname>)
//}}AFX_DATA_MAP
DDX_Control(pDX, ID_BTN_0, btns[0]);
DDX_Control(pDX, ID_BTN_1, btns[1]);
...
And that should work.
ClassWizard is the only thing that requires each button variable to be a separate member variable, the DDX_Control function does not care.

thanx for your help. I appreciate it.

That's a good start, but I need to know how then do I map all of the buttons in the array to call a single function when clicked that can tell which button was pressed.
Basically, my problem is this: I am writing a little program for testing very simple math. The program puts up a simple math problem such as "2 + 1 =", and the user is to press a button with the correct number as the answer, in this case "3". There are several of these buttons. Each should call essentially the same routine which just checks to see if the number on the button is the correct answer or not. How do I set these up as an array such that pressing any of them calls this one function with an Index in the array so that I know which one was pressed?
I'd sure like to avoid having a separate function for each of these buttons because I'm planning on having about 20 of them.
Thanks.

OK, I figured out how to map the buttons all to the same function. Here's the code:
BEGIN_MESSAGE_MAP(CButtonArrayTestDlg, CDialog)
//{{AFX_MSG_MAP(CButtonArrayTestDlg)
ON_WM_SYSCOMMAND()
ON_WM_PAINT()
ON_WM_QUERYDRAGICON()
//}}AFX_MSG_MAP
ON_BN_CLICKED(IDC_BUTTON1, OnButtonArray)
ON_BN_CLICKED(IDC_BUTTON2, OnButtonArray)
ON_BN_CLICKED(IDC_BUTTON3, OnButtonArray)
END_MESSAGE_MAP()
Now, when each of the buttons is pressed, it does call the correct function. But now how do I know which button was pressed?
|
|
|
|

Maybe you need to try this instead:
ON_CONTROL_RANGE(BN_CLICKED, IDC_BUTTON1, IDC_BUTTON3, OnButtonArray)
Note: The range of command IDs must be contiguous.
Handler functions for single commands normally take no parameters. With the exception of update handler functions, handler functions for message-map ranges require an extra parameter, nID, of type UINT. This parameter is the first parameter. The extra parameter accommodates the extra command ID needed to specify which command the user actually chose.
afx_msg void OnButtonArray( UINT nID );
When called, nID will be the ID of the button pressed.

I misunderstood your initial question. I think Blake Miller has given you the correct answer.

asdf.zip file is a zip file.
But, it can browsed in Explorer just like a folder.
How can I make this?

it is a shell extension, but i dunno exactly how it works... maybe michael dunn is the right one for this question

hi everybody,
i designed a dialog which i'd like to close by right-click anywhere inside it. For that, i overrided the WM_RBUTTONDOWN an i associated to it the following code :
<font style="color:blue;">void </font>CAboutDlg::OnRButtonDown(UINT nFlags, CPoint point) {
<font style="color:blue;">this</font>->OnClose();
CDialog::OnRButtonDown(nFlags, point);
}Unfortunately, it doesn't work 
i've been obliged to create a "OK" button which i hide, and instead of calling OnClose(), i call OnOk() :
<font style="color:blue;">void </font>CAboutDlg::OnRButtonDown(UINT nFlags, CPoint point) {
<font style="color:blue;">this</font>->OnOk();
CDialog::OnRButtonDown(nFlags, point);
}It now works, but i don't like this way of contourning the problem.
can anybody tell me why my first code doesn't work, and what i could do do resolve th pb ...?

Why not call EndDialog() 
Ant.
|
|
|
|

work fine thank you
anyway, do you have an idea of the reasons OnClose() doesn't work ?
would the virtual BOOL CWnd::DestroyWindow(void); have work better too ?

You would use DestroyWindow() for a modeless dialog and EndDialog() for a modal dialog.
OnClose() will call DestroyWindow() anyway IIRC. However without looking I can not recall why they are done differently. Now I will have to look and find out
Ant.
|
|
|
|
|
From MSDN CDialog::OnOK
"If you implement the OK button in a modeless dialog box, you must override the OnOK method and call DestroyWindow from within it. Do not call the base-class method, because it calls EndDialog, which makes the dialog box invisible but does not destroy it."
Had to look this up so here for your benefit too.
Ant.
