Change this to "program to" and you should be good to go. Thanks for allowing us to help.

Hi all,

I have written a CMS that uses the CHTMLEdView class as a HTML editor. The CMS also has a number of additional edit controls for things like a button name, a tooltip etc. When the CHTMLEdView has focus, and I click on one of the other Edit controls, then the cursor is hidden, which is a hassle for editting. When I then click on any of the other edit controls, the cursor re-appears, In other words, I always need to click two different edit controls after using the HTML editor before the cursor appears again. I have tried ShowCursor(TRUE) and ShowCaret() on the edit controls, but nothing seems to help. Has anybody got any ideas on the subject? Would be greatly appreciated.

Regards,
William

hi!

I want to use a C++ function which applies minimization on a math formula ( http://www.codecogs.com/d-ox/maths/optimization/nelder.php ) but I dont understand how to pass my formula as the first parameter.

There is even an example but I dont understand it...

double f(double *x) {
    double r = sqrt(x[0] * x[0] + x[1] * x[1]);
    return ABS(r) < 1E-12 ? 1 : sin(r) / r;
}

I dont know what's the unknown. "x"? "r"? Both?

My formula is: http://personal.telefonica.terra.es/web/episodio1/text3.gif

This is what I've made:

for (i=1;i<=numberOfAnchors;i++)
{
   errorsquare+= pow( abs( x[i] - xestim + y[i] - yestim ) - distance[i]  ) , 2 );
}
errorsquare=errorsquare/numberOfAnchors;

2 unknowns: "xestim" and "yestim".

My question is: how should I code/declare my formula so it is accepted by the C++ function ?

Thanks.

Well, supposing both your xestim and yestim are independent, you may rearrange your function such a way:

xestim -> z[0]
yestim -> z[1]

so that you'll get

double f (double * z)
{
  errorsquare = 0.0;
  for (i=1;i<=numberOfAnchors; i++)
  {
    errorsquare+= pow( abs( x[i] - z[0] + y[i] - z[1] ) - distance[i]  ) , 2 );
  }
  return errorsquare;
}

Now you have the f parameter of the nelder function..
dim is 2 (as you may guess).
The starting simplex points p are up to you (you've to provide, as in the example a 2x3 array), like the eps value and the maxit.

Of course I forgot it, but you know, such a operation has no influence in finding minimum (you may drop it). Wink | ;)

Cpallini, do you know about NelderMead algorithm?

Cause I dont know what initial points to use. I mean...

In that C++ function Points are 2x3 (3 points x-y).

But this function is payware, so I got this one: http://people.sc.fsu.edu/~burkardt/cpp_src/asa047/asa047.html

In this last one initial points are only 1x2, which I dont know what represents.

Code it's already running but I dont get valid points for any initial points. Frown | :(

EDIT: It's OK now. There would be 1 and only initial point. And it should be close to region in which I want to find a minimum. ^^

Hi All

I have two path source(LPCSTR pF)and destination(LPCSTR pT).I am getting values in pF at the run time like this pF="C:\\Hello\\adaf\\trt" and pT="C:\\Backup."
But when code start to copy cammand then it make backup but it's not make in proper way.It's make like that(C:\\Backup\\Hello,C:\\Backup\\adaf and C:\\Backup\\trt).But i need to copy in full path like that(C:\\Backup\\Hello\\adaf\\trt).I am ueing this code.

CFileOperation fo;
	CString tr=sourcepath;
			
 	int nLen = tr.GetLength();
		LPCSTR lpszBuf = tr.GetBuffer(nLen);
    	tr.ReleaseBuffer();
		LPCSTR pF=lpszBuf;
		
		LPCSTR pT="C:\\Backup";	
if(!fo.Copy(pF,pT));

Plz help me

What is it?

Why are you misusing CString::GetBuffer?

If you are use ;;ShellFileOperation you need to end the last file buffers with 2 (two) zero bytes. Read the docs from MS D'Oh! | :doh:

Press F1 for help or google it.
Greetings from Germany

What's wrong with:

CFileOperation fo;	
if (! fo.Copy(sourcepath, "C:\\Backup"))
    ;

That aside, have you stepped into the Copy() code to see when/how it is failing?

Hi all

The framework calls OnKillFocus() member function immediately before losing the input focus.

Just like that is there is any function that we can override when the window regains the focus.

Thanks and regards

What about OnSetFocus [^]?

Is there is any message handler for this function

Is is a message handler (it handles WM_SETFOCUS).
