Actually, .NET would deal with your memory leaks, eventually.

A modeless dialog needs to be a member variable. Otherwise, you've thrown a pointer to the wind, and have no way to do anything with it from there on in.

Reposting my own code is not much of a help. I need code that shows how to do it correctly.
'A modeless dialog needs to be a member variable. Otherwise, you've thrown a pointer to the wind, and have no way to do anything with it from there on in."
I've heard of this solution before, but how do I actually DO it? Just saying it works for most people, but , as I" am a tactical person at times, I need to see actual code.
What variable type does the dialog box need to be? CString, int, BOOL, or what? Apologies if I sound crabby, but there are millions pf sites out there on the 'ignorant net', and most issues I can resolve with research, trial, and error. However, there occassionally comes an issue to which everybody has an answer, but nobody wants to show how its actually done. What's the big M$DN secret on these subjects?
Thanks, again. I really appreciate it.

Try using a member variable of type CInvenStoryDlg. In your header
CInvenStoryDlg *m_pdlg ;
In your constructor(s) initialise it to NULL
m_pdlg = NULL;
Change creation code to use the member variable:
void CInvenStoryDlg::OnButtonNewitem()
{
m_pdlg = new CInvenStoryDlg ();
m_pdlg ->Create(IDD_DIALOG_NEWITEM, this);
m_pdlg->ShowWindow(SW_SHOW);
}
In you destructor check if is not NULL otherwise DestroyWindow.

I find that difficult to believe, in light of this comment:

Sometimes, things are so simple, we assume that an explanation is enough.
If you created a CMyDlg * locally, what would your member variable be, if not a CMyDlg * ? What else COULD it be ?
A member variable, of the right type. Set to NULL in your constructor. Set to a value when you show it. Reset to NULL and deleted both in your destructor and the code which hides it otherwise.

Is this right, in that you are creating another instance of CInvenStoryDlg?

At the point in which you are done with the modeless dialog.

Not creating another instance, but rather creating a child dialog [of which I am clueless]. I prefer dto do a modeless version, but want to see Modal code as well.
And thanks for the tip on "at the point of when you are through with it", but what I meant was where does the code GO? Probably CSomeClassName::OnDestroy(); but could you "dumb it down" for me? does code to destroy a child dialog go in the .cpp file for that dialog, or the .cpp file for the main dialog [parent that calls it]?
"Not in a child dialog" means :
that any code I write, [which is correct], will execute properly when used in the main dialog and by clicking the appropriate button on the main dialog. The exact same code will not work for a button on any of the child dialogs, except for the default AboutBox that MSVC6 included in the project. My guess is that I am not construction method[s] are wrong for the child dialogs that I made.
Thanks for the help .... message me on Y! at digitalmythogy

But you are in a CInvenStoryDlg method when you create another instance of CInvenStoryDlg. Is that your intention?
digitalmythology wrote: ...what I meant was where does the code GO?
You call DestroyWindow() whenever you are done with the modeless dialog. It's up to you to determine where that is.
digitalmythology wrote: My guess is that I am not construction method[s] are wrong for the child dialogs that I made.
I suspect this is true. Notice how the About box has its own CDialog-derived class.

Is there a simple way to change the BG color (and maybe text color also) of an editbox? I only need two colors to be toggled by clicking a button. I wanted to toggle the color of the button, but found out that it can only be done using images as buttons, which seemed too complicated for me.

Not really. An edit box is really nasty, as it paints itself outside the normal WM_PAINT method, so any owner drawing tends to get erased as you type. It can be done, but not without flicker, and not as trivially as, say, a button. To change the color of a button, you can derive a class from the button class, and draw the background yourself. No bitmap needed.

This doesn't work when you've also changed the background color of the dialog box itself.

ummm. no  Maybe you are thinking of WM_ERASEBKND?
Try it.
I posted an MFC example below.

Here's a Christmas edit box (adjust colors for your region/season/religion/etc):
(This is MFC code but API calls are similar)
CBrush RedBrush;
...
RedBrush.CreateSolidBrush(RGB(0xFF,0x00,0x00));
...
HBRUSH CMyDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if (nCtlColor == CTLCOLOR_EDIT)
{
pDC->SetTextColor(RGB(0x00,0xFF,0x00));
pDC->SetBkColor(RGB(0xFF,0x00,0x00));
hbr = RedBrush;
}
return hbr;
}

Hi All, 
I need to write some application that send some file ( it can be word document or some exe file ) to some other machine that have with him TCP connection.
The TCP connection is not my problem - my problem\question is  - how to read the file and send it to other side ? I know that i need to send the file as byte order - but i don't know how to do it.
Thanks for any help.

just opent the file in binary mode (e.g. fopen("foo.exe", "rb") ), read from (e.g. using fread) and the send it through the socket.
Where is it the trouble?
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

With Windows Sockets there's the TransmitFile() API (NT 3.51+).
You can also open the file, read a chunk of bytes into a buffer, send the buffer.
On the reveiving side create a file, receive a chunk of bytes into a buffer, write the bytes to
the file.
There are no byte order issues.

open file in binary mode and send chunk by chunk.. remember Sliding Window Protocol!
