Your not going to find that functionality I'm afraid.
I would suggest "Applied Cryptography" by Bruce Schneier if you want to roll your own. He's got some good source code to derive from in the back of the book. Use GDI+ to get easy access to the bits of most popular image file formats or just encrypt the whole file if you like.
Look into the CryptoAPI if you find you can't stomach the code directly.
Hope that helps.

Start with something simpler. Then when you are ready to ask questions, make them specific see the first message in the forum "How to get an answer to your question".
Also XOR is NOT encryption and the IDE "Class Wizard" has nothing to do with XOR.
There are all sorts of articles, sample projects and tutorials here at Code Project and at msdn.microsoft.com.

It would qualify as a simple cypherlink[^]. Granted, you will usually have something else jacking with the data like the feistel function in blowfish but even there the XOR is at the heart of the algorithm. If I remember correctly, it was at the heart of most of the techniques in "Applied Cryptography" but the book is not at an arms reach at the moment so I can't confirm that.
For what it's worth in defense of the person that was asking for some guidance.
Anyway, for what it's worth...

Ok, when I go back and read it again after you post I can see that, but you have to make some assumptions about the OP to get there.

hi
i did try most of the things to yesterday to display a message in a textbox by setdlgitemtext().
i tried this code too.
HWND hWndMessage = ::GetDlgItem(m_hWnd, IDC_Message ); // m_hWnd Is
if( ::IsWindow( hWndMessage ) )
{
// Try SendMessageTimeout(...)
SetDlgItemText(IDC_Message,"New Incoming Call ");
}
but if condoes not staify and msg does not display in a text box.
plz help me.
|
|
|
|

hWndMessage is probably NULL, so either the window m_hWnd has not been created yet, or a control with the ID of IDC_Message does not exist on the dialog, which makes GetDlgItem return NULL.
Check your control ID's in the resource editor and make sure they are assigned properly.

yes i did try the code which u have to me yesterday with my code.
but nothing is happening.
i did it like that.
void sipxmngr::handleOffering(SIPX_CALL hCall)
{
sipxAudioEnableSpeaker(g_hInst,SPEAKER);
//sipxmngr dlg;
char cCallId[512];
int new_call_stat=1;
sipxCallGetID(hCall, cCallId, sizeof(cCallId));
HWND hWnd;//declare is Global
hWnd=CreateWindow("EDIT","",WS_CHILD|WS_VISIBLE,0,0,150,23,m_hWnd,NULL,AfxGetInstanceHandle(),NULL);
:: setWindowText(hWnd,"Test");
//SetDlgItemText(IDC_Message,"New Incoming Call ");
//HWND hWndMessage = ::GetDlgItem(m_hWnd, IDC_Incoming_New_Call); // m_hWnd Is
//
//if( ::IsWindow( hWndMessage ) )
//{
// // Try SendMessageTimeout(...)
// SetDlgItemText(IDC_Incoming_New_Call,"New Incoming Call");
//}
sipxCallAccept(hCall);
//SetDlgItemText(IDC_Message,"New Call");
//SetDlgItemText(IDC_Incoming_New_Call,"Incoming Call Accepted");
//AfxMessageBox("Hello");
//SetDlgItemText(IDC_Message,"New Incoming Call From cCallId");
}
got nothing.

ah no HWND hWnd;//declare is Global The meaning of you should declare this variable
in your class not function and one another problem use from this code instead SetDlgItemText(IDC_Incoming_New_Call,...)
ok so you try this:
1-Declare one hWnd in your class(header file)
2-use createwindow
3-instead IDC_Incoming_New_Call use ::setWindowText(hWnd,your message);
4-in the end Destroy this hwnd
5-answer to me it work or dosent work,please
6-where you use handleOffering

You can use from pWnd in contextmenu like this
if (pWnd->m_hWnd!=m_Tab.m_hWnd)
....

You could check the pWnd parameter of OnContextMenu handler and not display your context menu if it's the tab control window.
i.e.
if (pWnd != pTabCtrlWnd)<br />
{<br />
}<br />
