add message handler for ID_BORDERCOLOR, then inside the message handler,
add the code

CColorDialg dlg;
dlg.DoModal();
COLORREF clr = dlg.GetColor();

are you trying to know the status of a port?

the open (Create of CSocket) on trying to open a port that is already listening.

See the sample from MSDN[^]

if we fail to bind to a specified port of listen to a specified port fails, which means that, the port is in use or invalid.

I think wha you were doing is wrong.

Seems you need something like this.

this is code can't be applied directly... Just a logic "how to do"

class CXYZ
{
public:
	SetListBoxHandle(CListBox* pListBox);
	Display();
};

class CMyDialog
{
private:
	CXYZ m_xyz;
	CListBox m_ListBox;
	BOOL OnInitDialog()
	{
		m_xyz.SetListBoxHandle(&m_pListBox);
	}
	void OnBtnClick()
	{
		m_xyz.Display();
	}
};

sorry I left office yesterday...

for that purpose, there's in Set handler function.
keep that in a member varible (pointer type of CListBox) and call when it is required.

l1->AddString("Abc");
}

actually set handler function should be call from the owner of list. i.e in this case, the dailog class. he also contains the XYZ Class too.

so he is becoming as mediator for communication.

set set handler should be called from OnInitDialog or from the constructor.

in the class, you pls add CListBox* m_pList;

in the set handler function
m_pList = pListBox;

inside display function, you can use m_pList, if you properly set the handle.

it's actually not big deal.

I dont have time to write code, that is why im explaining through these steps.

you are calling an invalid pointer.

i.e ListBox pointer is invalid

yes i did.

actually i was calling the display function with a wrong object.

i'm facing one another problem is that i have to add image & string simultaneously in the list i'm using listctrl for it.

but not getting the appropriate solution.

thanx

Sarath C9-Jul-06 22:32

9-Jul-06 22:32

either derive a class from CListBox and handle it inside or use a listctrl instead. Anyway it's easy to handle it using Image lists or GDI drawing.
Check MSDN for more information. all controls have been illustrated in sample application called CTRLTEST. or search CP for more information.

Hi Dinu,
there's is no message map, that can map right button click
so derive a class from CButton.
Add WM_RBUTTONDOWN message handler and the needful there. Subclass or add control variable for your button.

now you are done.
