Fire connection point event from ATL Service

pratik_mishra3511-Oct-10 2:17

11-Oct-10 2:17

Hi all,

I have been working on this project where i receive a stream of data over a UDP port. This Data is to be processed and the result is to be distributed to the clients. To accomplish this end i have created an ATL service along with a connection point interface. Now the actual problem is how to call the Fire_Event method as i have created a thread from the service which reads the data stream. Can someone please help me as to how can i call the fire method as the functions that reads a stream and should generate the event OnDataChange is not member of the Connectionpoint interface.

Thanks and regards,
Pratik

I used vc6.0 ->Create a new Activex project, MFC ActiveX ControlWizard
I created a new button,and want to the button shows Tooltip when the mouse in the button's rect.
here is my code:
BEGIN_MESSAGE_MAP(CTestCtrl, COleControl)
//{{AFX_MSG_MAP(CTestCtrl)
ON_WM_CREATE()
//}}AFX_MSG_MAP
ON_OLEVERB(AFX_IDS_VERB_PROPERTIES, OnProperties)
//add Tooltip Message
ON_NOTIFY_EX( TTN_NEEDTEXTA, 0, OnToolTipNotify )
ON_NOTIFY_EX( TTN_NEEDTEXTW, 0, OnToolTipNotify )

END_MESSAGE_MAP()

BOOL CTestCtrl::OnToolTipNotify( UINT id, NMHDR * pNMHDR, LRESULT * pResult )
{
TOOLTIPTEXT *pTTT = (TOOLTIPTEXT *)pNMHDR;
UINT nID =pNMHDR->idFrom; //
pTTT->lpszText ="Test";
pTTT->hinst = AfxGetResourceHandle();
return(TRUE);
}

it works well in "VC6" and "ActiveX Control Test Container",but in vb or C# or ie,it doesn't show the tooltip,
who can tell me ,how can i do for this issue.
thanks

Problems to print

Hi All

I have problems to send print in my application.
If I send print and if I change my view before ready to print, all commands will be cancelled.
I send direct to print, print setup is not showed, the view can be closed, and OpenDocumentFile doesn't show this view if command is print;
My application needs fill a graph, reading from a database, while not read all data he is not ready to print, I have a flag to do this.
See my code:

//if the document was found, try to print it
        if(pDoc!=NULL)
        {
            //if document is ready for printing, print it now
            dwTick=::GetTickCount();
            nPrintWindowTimeout=5;
            if(nPrintWindowTimeout<0)
                nPrintWindowTimeout=0;
            dwWaitLimit=(DWORD)nPrintWindowTimeout*1000;
            if(pDoc->IsReadyForPrintWindow() || (dwTick < item.m_dwTickStart || dwTick - item.m_dwTickStart > dwWaitLimit) )
            {
                //remove screen from the queue
                m_arPrintQueue.RemoveAt(0);
                //print
                pDoc->SetPrinting(TRUE);
                if (pDoc->GetView()) 
                {
                    if (item.m_bPrintSetup == TRUE)
                        pDoc->GetView()->SendMessage(WM_COMMAND, ID_FILE_PRINT_SETUP);
                    else
// But if I change my view this is never executed, the message queue is not keeping this in another view
// This is sended in a CView, not in MainFrame, my derived CView process WM_COMMAND
                        pDoc->GetView()->SendMessage(WM_COMMAND, ID_FILE_PRINT);
                }
                pDoc->SetPrinting(FALSE);
                pDoc->OnCloseDocument();
            }
        }
    }

Somebody, can help me?
Thank you

Why normal virtual function required blank body in base class

Hi,

I have following block of code,

class Base
{
       public:
          Base()
		  { 
		     cout<<"Constructor: Base"<<endl;
		  }
          ~Base()
		  { 
			  cout<<"Destructor : Base"<<endl;
		  }
		  virtual void fun();
		   
};
class Derived: public Base
{
      
       public:
           Derived()
		   { 
			   cout<<"Constructor: Derived"<<endl;
		   }
           ~Derived()
		   { 
			   cout<<"Destructor : Derived"<<endl;
		   }
		    void fun()
		  {
		    cout<<" in der";
		  }
};
int _tmain(int argc, _TCHAR* argv[])
{
	Derived obj;
        obj.fun();
	getche();

In above code virtual fun() is showing error that it not resolved. If i add blank body then Derived class's Fun()is called. Is it necessary to have blank body for virtual function in base class and what is reason of this. OMG | :OMG:

Thanks
abm

Hi,
Your Base::fun() member is declared but not defined, so the linker complains.
You have to define it somewhere either as pure virtual virtual void fun() = 0; or otherwise:

//do nothing
virtual void Base::fun(){};

Enable moving marquee progress bar (C++, ATL/WTL, XP, VS2008)

karuuzo5-Oct-10 6:58

Hi all!

Sorry for my english, I use it very rarely and have bad grammer Sniff | :^)

I tired to get moving marquee progress bar in my project. I read many articles, try different variants, but nothing work. Progress bar freezes in left side and only, what I can do, change it size, by varying range.

All, wat I do:
1. add refference into manifest file for common controls:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
	<assemblyIdentity 
    version="1.0.0.0" 
    processorArchitecture="X86" 
    name="XPProgress" 
    type="win32" />
	<description>XPProgress</description>
	<dependency>
		<dependentAssembly>
			<assemblyIdentity 
        type="win32" 
        name="Microsoft.Windows.Common-Controls" 
        version="6.0.0.0" 
        processorArchitecture="X86" 
        publicKeyToken="6595b64144ccf1df" 
        language="*" />
		</dependentAssembly>
	</dependency>
</assembly>

2. change supported windows versions:

#define _WIN32_WINDOWS 0x0501

3. enable common controls:

::AtlInitCommonControls (ICC_COOL_CLASSES | ICC_BAR_CLASSES | ICC_PROGRESS_CLASS);

4. create simple dialog with progress bar:

IDD_DIALOG DIALOGEX 0, 0, 331, 44
STYLE DS_SETFONT | DS_MODALFRAME | DS_FIXEDSYS | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "Dialog"
FONT 8, "MS Shell Dlg", 400, 0, 0x1
BEGIN
    DEFPUSHBUTTON   "OK",IDOK,137,23,50,14
    CONTROL         "",IDC_PROGRESS,"msctls_progress32",WS_BORDER,7,7,317,14
END

5. create dialog class:

class CDlgMain : public  CDialogImpl<CDlgMain>
{
public:
	enum { IDD = IDD_DIALOG };

	CDlgMain(void);
	~CDlgMain(void);

	BEGIN_MSG_MAP(CDlgMain)
		MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)
		MESSAGE_HANDLER(WM_CLOSE, OnClose)
		COMMAND_ID_HANDLER(IDOK, OnOK)
	END_MSG_MAP()


	LRESULT OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/);
	LRESULT OnClose(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/);
	LRESULT OnOK(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/);

};

6. on button click - enable/disable marquee option for toolbar:

LRESULT CDlgMain::OnOK(WORD /*wNotifyCode*/, WORD wID, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
{
	DWORD dwWinLong = ::GetWindowLong(GetDlgItem (IDC_PROGRESS), GWL_STYLE);

	if (dwWinLong & PBS_MARQUEE)
	{
		::SetWindowLong(GetDlgItem (IDC_PROGRESS), GWL_STYLE, dwWinLong & (~PBS_MARQUEE));
		::SendMessage(GetDlgItem (IDC_PROGRESS), PBM_SETMARQUEE, (WPARAM) 0, (LPARAM) 100);
	}
	else
	{
		::SetWindowLong(GetDlgItem (IDC_PROGRESS), GWL_STYLE, dwWinLong | PBS_MARQUEE); 
		::SendMessage(GetDlgItem (IDC_PROGRESS), PBM_SETMARQUEE, (WPARAM) 1, (LPARAM) 100);
	}
	return TRUE;
}

Result is freezed progress bar, that not moving anywhere Frown | :(

I discovered, than, when I change progress bar range to smaller values, visible progress line grow biger, but nowhere moves.

::SendMessage(GetDlgItem (IDC_PROGRESS), PBM_SETRANGE, 0, MAKELPARAM(0, 20));

Someone can tell me, what I do wrong, or what I miss? I read many articles in different sites and forums, but there say, that is enough to enable progress bar animation.

Hi,

You are mixing the control style, must have PBS_MARQUEE, and it's state.

Set the control style either in your DIALOG resource descriptor:

CONTROL         "",IDC_PROGRESS, "msctls_progress32", PBS_MARQUEE | WS_BORDER, 23, 38, 80, 14

or in your OnInitDialog() handler:

LRESULT OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, LPARAM /*lParam*/, BOOL& /*bHandled*/)
{	
    // ...
    CProgressBarCtrl(GetDlgItem(IDC_PROGRESS)).ModifyStyle(0, PBS_MARQUEE);
    return TRUE;
}

and in your OnOK() handler switch the moving state, for instance:

LRESULT OnOK(WORD /*wNotifyCode*/, WORD /*wID*/, HWND /*hWndCtl*/, BOOL& /*bHandled*/)
{	
    static bool bAnimated = false;
    CProgressBarCtrl(GetDlgItem(IDC_PROGRESS)).SetMarquee(bAnimated = !bAnimated);
    return 0;
}

cheers,
AR

{
    static bool bAnimated = false;
    CProgressBarCtrl(GetDlgItem(IDC_PROGRESS)).SetMarquee(bAnimated = !bAnimated);
    return TRUE;

In your original post you showed the following line of code:

::SendMessage(GetDlgItem (IDC_PROGRESS), PBM_SETMARQUEE, (WPARAM) 1, (LPARAM) 100);

so I presume your SetMarquee() method does something similar. The LPARAM value in this call affects the speed of the marquee display: the higher the value the slower the marquee. Try setting it to zero for the default behaviour.

CProgressBarCtrl::SetMarquee from atlctrls.h (WTL):

BOOL SetMarquee(BOOL bMarquee, UINT uUpdateTime = 0U)
{
    ATLASSERT(::IsWindow(m_hWnd));
    return (BOOL)::SendMessage(m_hWnd, PBM_SETMARQUEE, (WPARAM)bMarquee, (LPARAM)uUpdateTime);
}

Default is 0L

Dynamic Owner-Drawn CListBox Derivative - Owner Draw Problem

Kyudos3-Oct-10 13:00

Kyudos

3-Oct-10 13:00

I'm trying to create a pop up list box to display some drawing line styles which are stored in an XML file. I want to display the line and then the name of the style (i.e., the items have strings).

So I derived a class from CListBox, added in some sizing code and the relevant DrawItem function, and dynamically CreateEx'd this to popup off a button in my test dialog app.

However, I'm not getting any owner-draw messages to my popup - it's blank! If I take off the LBS_OWNERDRAWFIXED|LBS_HASSTRINGS style the popup is correctly populated with the style name strings. I added an owner-draw list box to the dialog and re-classified it to use my listbox class, and barring some item sizing issues it draws the items the way I want them drawn.

So what am I not appreciating about the dynamically created version? Where are is WM_DRAWITEM messages going?

Cheers!

Kyudos3-Oct-10 17:24

I can sort of make this work, by putting the owner-draw list box 'full-screen' on a borderless dialog (ick!) and then positioning that. But then I run into problems dismissing the dialog when the user clicks off it, and sorting out where the messages go. It would be nicer and neater if the dynamic way worked...

its not possible to store CComboBox objects into CMap or CList since copy constructor for CComboBox is not available. However you may do it as,

//if your key is of integer type
CMap<int, int, CComboBox*, CComboBox*> m_map;

sample to store data

CComboBox *pBox = new CComboBox();
CRect rc(0, 0, 100, 50);
UINT nId = 100;
pBox->Create(SW_HIDE, rc, this,  nId);
m_map[m_id] = pBox;
