But you are in a CInvenStoryDlg method when you create another instance of CInvenStoryDlg. Is that your intention?

You call DestroyWindow() whenever you are done with the modeless dialog. It's up to you to determine where that is.

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; //class member in MyDlg.h
...
// in CMyDlg consructor
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;
}

As soon as I can, I'll get you a working, practical piece of real-worl code. For now though, try this from MSDN :

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 Confused | :confused:

- 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?

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!

Like using ClassWizard (Ctrl+W)? Of course, you can always do it manually.
