So what is the question? If the purpose is to calculate the time taken only, then consider using the clock of <ctime> header. Then calculate the time taken to complete the task, pass different number of parameters to it and see the results.

C++

#include <iostream>
#include <ctime>

int main() {
    unsigned int start = clock();
    your_function(param); 
    std::cout << "Time taken in millisecs: " << clock()-start;
    return 0;
}

This is a native way of doing so, but I would recommend that you try using the API which so ever OS you are using, for example on Windows there are many ways to get the service of a stopwatch in Win32 or even better in Visual C++'s .NET implementation.

What do you mean with ADT?

Presumably, abstract data type.

I believe you are right, however I wonder how could you measure the performance of an abstract data type?

Reading it seemed pretty obvious to me that point it to measure the performance of the data structures when they contain the ADTs with the given functional methods

Solution:
1 - Write a ADT
2 - Create method to populate ADT with random data using a fixed seed.
3 - Write data structures.
4- Write method that creates number of ADTs and creates data structure with number given
5- Write method that inserts, searches and deletes a single newly create ADT
6- Make sure all of that works
7- Add timing to 5 and write times out

Good afternoon friends. Please how do I make this program quoted the following link function in the virtualbox, for example I downloaded the tutorial and no disk image or anything. Please for I am beginner and I am interested in the subject of freestanding but do not find anything on the web. If someone can help me thank you or not. Already Obrigadoe God Bless ...

That article is somewhat involved and would not be my first choice for a beginner. Why not start with something a little less aggressive?

Draw and re-pos CStatic controls in CDockablePane

Good night friends. Sorry if I sound a bit rushed, but that is for me (especially) is very important to know does. And since someone there on the other side has the answer to my doubts, Please me of this force, since I am also not starting there, and yes seeing the two modes in parallel. Already Thank you and God Bless ...

Hi all,

I have spend already many hours to find the reason of my current problem.

I have a CDockablePane, in which I am placing a lot of CStatic controls. The CStatic controls I am using to display bitmaps. A dockable pane is designed for resizing at any time. Therefore I try to recalculate the positions of each CStatic after OnSize is called.

With some CStatic controls it is running well. But when I am adding an additional control, I am getting strange problems: The pane is not repainted properly and OnPaint is recalled cyclically.

My code (partially):

Header:

class CPaneCtrlPLC : public CDockablePane
{
	DECLARE_DYNAMIC(CPaneCtrlPLC)

public:
	CPaneCtrlPLC();
	virtual ~CPaneCtrlPLC();

protected:
	DECLARE_MESSAGE_MAP()
public:
	afx_msg int OnCreate(LPCREATESTRUCT lpCreateStruct);
	afx_msg void OnSize(UINT nType, int cx, int cy);

private:
	CStatic m_Ctrl_PLCLED[6];
	CStatic m_SwitchCtrl;
	CStatic m_Ctrl_test;

C-File:

int CPaneCtrlPLC::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
	if (CDockablePane::OnCreate(lpCreateStruct) == -1)
		return -1;

	m_ColorSieGreen = RGB(0, 153, 153);
	m_ColorSieWhite = RGB(251, 253, 253);
	m_ColorText = RGB(230, 228, 193);
	m_ColorBgnd = RGB(119, 117, 127);
	m_BrushSieGreen.CreateSolidBrush(m_ColorSieGreen);
	m_BrushBgnd.CreateSolidBrush(m_ColorBgnd);

	m_BitmapSWITCHSTOP.LoadBitmapW(IDB_SWITCH_STOP);
	m_bitmapLEDOFF.LoadBitmapW(IDB_LEDOFF);
	m_bitmapLEDRED.LoadBitmapW(IDB_LEDRED);
	m_bitmapLEDGREEN.LoadBitmapW(IDB_LEDGREEN);
	m_bitmapTest.LoadBitmapW(IDB_LEDGREEN);

	// TODO:  Add your specialized creation code here
	DWORD dwStyle = WS_CHILD | WS_VISIBLE | TVS_SHOWSELALWAYS | SS_BITMAP;
	m_SwitchCtrl.Create(NULL, dwStyle, CRect(0, 0,0,0),this);
	m_SwitchCtrl.SetBitmap(m_BitmapSWITCHSTOP);

	int iLed;
	for (iLed = 0; iLed < MaxNumPLCLeds; ++iLed)
	{
		DWORD dwStyle = WS_CHILD | WS_VISIBLE | TVS_SHOWSELALWAYS | SS_BITMAP;
		m_Ctrl_PLCLED[iLed].Create(NULL, dwStyle, CRect(xPosPLCLEDS,(yPosPLCLEDS + (26* iLed)), 0, 0), this);
		m_Ctrl_PLCLED[iLed].SetBitmap(m_bitmapLEDOFF);
	}

	{
		DWORD dwStyle = WS_CHILD | WS_VISIBLE | TVS_SHOWSELALWAYS | SS_BITMAP;
		m_Ctrl_test.Create(NULL, dwStyle, CRect(xPosPLCLEDS + (17 * iLed), yPosPAELEDS + 20, 0, 0), this);
		m_Ctrl_test.SetBitmap(m_bitmapTest);
	}
...

I was able to strip the OnPaint(0) function to a minumum to reprocude the problem.
If I comment out the re-positioning of the m_Ctrl_test, everything works fine, but with this statement I have the problems.

void CPaneCtrlPLC::OnPaint()
{

	LOGMSG(LOG_TEST, _T("Repaint"));

	CPaintDC dc(this); // device context for painting

	CRect rect;
	GetClientRect(&rect);

	//Manual BG repaint
	dc.FillRect(&rect, &m_BrushBgnd);


	m_SwitchCtrl.SetWindowPos(NULL, 10,10, 0, 0,
		SWP_NOSIZE | SWP_NOACTIVATE | SWP_NOOWNERZORDER | SWP_NOCOPYBITS);

	m_Ctrl_test.SetWindowPos(NULL, 10, 100, 0, 0,
		SWP_NOSIZE | SWP_NOACTIVATE | SWP_NOOWNERZORDER | SWP_NOCOPYBITS);

	return;
}

Any ideas, what could be wrong?

Solved by myself!

In OnPaint() I changed the positions of the CStaticControls.
Of course this is causing "recursive" WM_PAINT calls.

I moved this code to other functions (OnSize, OnTimer,...), now it works!

Customize filter control of CHeaderCtrl

aks.9-Sep-15 4:50

I have a CListCtrl in my MFC dialog application.
I enabled the HDS_FILTERBAR for List control the by the following code.

CHeaderCtrl* pHeaderCtrl = m_myListCtrl.GetHeaderCtrl();
 pHeaderCtrl->SetDlgCtrlID( IDC_LIST1 );
 HDITEM hdItem;
 ZeroMemory( &hdItem, sizeof( HDITEM ));
 hdItem.mask = ( HDI_FILTER );
 pHeaderCtrl->ModifyStyle( 0, HDS_FILTERBAR );
 hdItem.type = HDFT_ISSTRING;

The filter is displayed.
However I would like to change the background color and font of the Edit control and button in the filter section.
How can I achieve it.

The CEdit class inherits from CWnd so you can use SetFont to change the font. You can probably set the background colour by subclassing the window. Changing the colour and image in a button can be done in similar ways. Google should find you some samples.

aks.15-Sep-15 20:55

Thank you for the comment.
I tried by subclassing the Header control.
But I could not find any options to get the edit control and button from the CHeaderCtrl.

So who put them in the header in the first place?

aks.16-Sep-15 1:45

Ok. I got it, I used FindWindoEx to find the WC_EDIT in the header.
I think the filter button is not exactly a button. Its a bitmap.

Richard MacCutchan16-Sep-15 2:13

I don't think that is the best way. You put the items in the header so you should be able to get their handles quite easily using the methods of the CHeaderCtl object.
