Event Handler -Please help me

[prathuraj]

I have created a IP address control dynamically. How to add a event handler for those controls. How to use event handlers with dynamically created control.

[Arman S]

Generally, three things to be done; *) decide which exact command to handle *) prepare the handler function [whose prtototype is influenced by the cammand to be handled] *) map the command to the handler As for ip control, I guess you are trying to handle the IPN_FIELDCHANGED notifycation. So you would have a handler like this;

void CMyDialog::OnFieldChangedIpAddress(NMHDR *pNMHDR, LRESULT *pResult)
{
LPNMIPADDRESS pIPAddr = reinterpret_cast(pNMHDR);
// your code here ...
*pResult = 0;
}

And map it to the notifycation inside BEGIN_MESSAGE_MAP/END_MESSAGE_MAP pair like so;

ON_NOTIFY(IPN_FIELDCHANGED, IDC_MYIPADDRESS, OnFieldChangedIpAddress)

ON_NOTIFY(IPN_FIELDCHANGED, IDC_MYIPADDRESS, OnFieldChangedIpAddress) I cant use the control id directly because i created control dynamically. How to add On_notify for dynamically created one

[Arman S]

You can and hou have to. The last parameter of CIPAddressCtrl::Create takes the id of the newly creating control. So define an id inside resource.h file and pass it to the Create method. PS. To define an id, go to menu option Edit\Resource Synbols... and then choose New... .

How do you make IP address control ? CIPAddressCtrl::Create(....,UINT nID); or CIPAddressCtrl::CreateEx(...,UINT nID);

how to use this id to call notify event

[Arman S]

You should not bother about calling notify events. This is done by the system. So your job is to handle the notifyfication only. See my first post; it describes what you need to do.

CIPAddressCtrl* pIPAdd = new CIPAddressCtrl; pIPAdd->Create(WS_CHILD|WS_VISIBLE|WS_TABSTOP|WS_BORDER|ES_AUTOHSCROLL, CRect(x,y,x+sz.cx,y+sz.cy),this,nID);
