I was thinking that for modeless dialog you need to override OnCancel,OnClose functions and call DestroyWindow() in them.

Only if you are not destroying d by yourself in the calling code. If in the function where you call the dialog the way you mentioned, you also have

delete d;

somewhere, everything is fine.

Otherwise, you have a memory leak, the d pointer is never deleted. To do so, override PostNcDestroy like this

void CShowDlg::PostNcDestroy() 
{
	delete this;
	CResizableDialog::PostNcDestroy();
}

That's all.

Secondly should the second statement in above code be d=new midialog(this);

Nope, not necessarily.

hello,
no i havent done anything such as delete d in my program.whatever code for modeless dialog i have written i have told you.I havent also overiden PostNcDestroy().So as per your suggestion i should overide the virtual function PostNcDestroy()in the class of respective dialog resource.
and code would be
midialog::PostNcDestroy()
{
delete this;
CDialog::PostNcDestroy()/*coz mu dialog class midialog is derived from CDialog and not from CResizableDailog as in your code snippet*/
}

is this ok?
one more doubt,is there no need to overide OnClose(0 with DestroyWindow()?are you sure?and we are writing delete this so isn't d=new midialog(this);necessary?

sorry askig same questions but since i am a begineer i feel the need to get things clear.
thanks
plz reply

SSL security for website

I am developing a web server with SSL security in it in VCS 2005.
I am using SSLStream class to handle the data transfer between the web server and
the browser.
After connection is established I am calling a SSLStream's Authinticateserver method but after that i don't any reply from the browser.
For simple client application we have authinticateclient method so it works fine.
But how can i do it for a browser.
Or if anyone can tell alternative ways to develop it.

CDialogBar and CFrameWnd

Does a CDialogBar's parent always have to be a Frame Window?

   IIRC, yes and no. That "Frame Window" concept is a MFC concept, not a native Windows concept, and as such can be tricking a little bit. I previously tricked it such that I could host a CToolBar and CDialogBar in normal (modeless, actually) dialog windows.

   I am pretty sure that messing with the CWnd::IsFrameWnd() function is the first place to get started.

   Peace!

FTP Problem

Could some please please help me with the following:

I'm using the following simple code to connect to an ftp site.

CInternetSession sess(_T("TestProgram/1.0"));

sess.SetOption (INTERNET_OPTION_CONNECT_TIMEOUT, 30);
sess.SetOption (INTERNET_OPTION_RECEIVE_TIMEOUT, 30);
sess.SetOption (INTERNET_OPTION_SEND_TIMEOUT, 30);

CFtpConnection* pConnect = NULL;

try
{
pConnect = sess.GetFtpConnection"serveraddress", "user", "password", 21, 0);
}

catch (CInternetException* pEx)
{
TCHAR sz[1024];
pEx->GetErrorMessage(sz, 1024);
AfxMessageBox(sz);
pEx->Delete();
}

It works fine for several ftp sites. However, when I go to a customers internal network and try to connect to their ftp site I get 'The operation has timed out' everytime.

If I go to a cmd window.
'ftp'
'open servername 21'
Connects fine with anonymous (but no permissions to do anything).
Then specify user
'user username password'
Connects fine allowing me to read write etc...

Under dos I can do it, but windows I can't!!!

I haven't a clue why?
Could some one give me a clue to what I am doing wrong.

Really appreciate any help or pointers!

Eternally grateful

I'm not well versed in this subject but have you tried hitting the internal network with IE. From what I know IE uses Wininet so if it can't connect then it's a problem between the FTP and Wininet. Possibly.

foloowing the code
void CGraphDialogDlg::OnBrowse()
{
// TODO: Code für die Behandlungsroutine der Steuerelement-Benachrichtigung

static char BASED_CODE szFilter[] = "(*.dlm)|*.dlm||";
CString cstrBuff;

What CFolderDialog are you using? It's not the CodeProject CFolderDialog nor WTL's CFolderDialog because they don't accept a BOOLEAN as their constructor's first argument. Without this information and without the source of CFolderDialog we can't answer your question.

Re: Browse dialog question

Mukhan27-Jul-05 1:15

CFolderDialog is publically inheriting from CFileDialog

class CFolderDialog : public CFileDialog
{
DECLARE_DYNAMIC(CFolderDialog)

public:
CFolderDialog(BOOL bShowFilesInDir = FALSE,
LPCSTR lpcstrInitialDir = NULL,
DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
LPCTSTR lpszFilter = NULL, CWnd* pParentWnd = NULL);
~CFolderDialog();
.
.
.

Now have a look please ....

Does the same thing happen with CFileDialog?

If you are wanting to browse for a folder, why not use SHBrowseForFolder() instead?

Name of File which is opened in window

I want to get file name which is opened in a window by using handle of that window.
I can get Application name by opening process and using GetBaseModuleName.
I know window has file name (with application's name) in window's title, but I want to get it by some method/function, as every application has different style of showing it.

Can any one help.

Re: Name of File which is opened in window

David Crow27-Jul-05 3:03

There is no standard method for obtaining this as, like you say, every application has its own method for displaying and storing the name of the file it is currentry working on.

If you want to go low-level and ask the OS this question, see here for what is involved.

Hello DavidCrow,
Thanks for your suggestion. Actually I know about file system filter drivers,
but I want to know is there any simple method. Your suggestion make me possible to decide future solution.

Thank you again. Smile | :)
