I have compiled a single-document program and overload 'OnSize ' of CMainFrame,below is my code.
void CMainFrame::OnSize(UINT nType, int cx, int cy)
{
CFrameWnd::OnSize(nType, cx, cy);
CRect rect;
GetWindowRect(&rect);
if(rect.Height() < 200)
rect.bottom = rect.top + 200;
if(rect.Width() < 200)
rect.right = rect.left + 200;
MoveWindow(rect);
}
Though the length and width of the window are all greater than 200, it twinkles very much. How can I keep it from twinkling?
Still has , and how to make maximize , minimalize and the restore of window and system menu lose efficacy ?

I would try doing this in the OnSizing message instead. OnSize occurs after the window has been sized. OnSizing occurs right before the window will be resized.
If the effect that you are trying to create is to make sure that a window can be no less than a certain size, then you will actually want to handle the WM_GETMINMAXINFO message. This will allow you to set the max and min dimensions of you window. Then when the user tries to resize the window, they will not be able to drag the border past the dimensions that you have specified.

I have 2 text boxes, one for inputting numbers and the other is a read only box that reads in that number. Depending on whether that number is even or odd, the read only box changes its background to green(even) or red(odd). However, the text inside the read only box then flickers when it's displayed. How do I fix this?
This is what I have done:
HBRUSH CSmallDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
CEdit * pEditReadOnly = (CEdit *)GetDlgItem(IDC_EDIT_DISPLAY); //read only
HWND hWndReadOnly = pEditReadOnly->GetSafeHwnd();
if(m_brush)
DeleteObject(m_brush);
CString input_value;
m_INPUT_BOX_VALUE.GetWindowText(input_value); //get value from input
m_DISPLAY_BOX_VALUE.SetWindowText(input_value); //read box displays it
long int number = atoi(input_value); //convert input_value to integer
if(nCtlColor == CTLCOLOR_STATIC &&
hWndReadOnly == pWnd->GetSafeHwnd())
{
pDC->SetBkMode(TRANSPARENT);
if (number % 2 == 0) { // if even change background to green
m_brush = CreateSolidBrush(RGB(0,255,0)); // green background
pDC->SetTextColor(RGB(0,0,0)); // black text
}
else { // else it is odd (red)
m_brush = CreateSolidBrush(RGB(255,0,0)); // red background
pDC->SetTextColor(RGB(255,255,255)); // white text
}
hbr = m_brush;
}
return hbr;
}

Please use the <pre> tag when posting code samples; it's nice to see indentation 
I don't know the answer off-hand, but i might try
pDC->SetBkMode(OPAQUE);
pDC->SetBkColor(RGB(0,255,0));
instead of
pDC->SetBkMode(TRANSPARENT);

That doesn't get rid of the flicker.
Thanks though.

Are you setting the text each time you change the back color?

? i'm pretty sure you were right. It took me a while to figure it out though. If you're that good not thinking, then you must be scary when you think.

Ok, totally didn't pick up on this the first time through, but - You are setting the text for the control each time OnCtlColor() is called. Remember, OnCtlColor() is called for more than just static text controls - your edit box is triggering it also. A much better way (and one which will probably eliminate your flicker) is to synch the text within an EN_CHANGE handler for the edit box, and set only the color within the OnCtlColor() function.

Suppose my ISP allows to give more information than normal ISPs does. Like it gives tells the user is their CLI number is wrong or they should connect at another number because this server is having a lot of load. I want my RAS dialer to recognize this stuff. Can I do without having to communicate directly with modem or terminal. What could be the possible way to workout this stuff.
Thanks in Advance.

How does it work when I want to send a file through my socket??
I guess I have one clue: I read each byte in the file and send it over to the client from the server. and the client will receive each byte and then make a file with a usual file creating function, such as fopen(...), and the save each byte in that file.
But I'm not sure my clue is working!
I'm NOT using MFC (which is VERY strange to be me! )

No 
But I've figure it out how it works with multithreaded server anyway now...

Basialy ur idea is corret..!! and you must care about stream/datagram and if u can handle the solution in such a way that the handshaking...that s better...if the client send a buffer and waiting for acknowledge and if the acknowledge get ,sene the next ,otherwiese resend the same...

Hi.
I am working on a program using the doc/view architecture. There is basically the program. There is a modeless dialog box where the user enters some information. When the user clicks "Apply" the dialog box sends a message to CMainFrame. From there, CMainFrame sends a message to CChildView. CChildView then draws the information as text inside its area.
I do not know how to send CChildView a message within CMainFrame. I am using the same technique Promises uses in Chapter 8 dialog 2 program (example of modeless). The only difference is he did not implement the program using doc/view. I am. In doc/view I do not know how to send a message from CMainFrame to CChildView because there is not CChildView object defined in CMainFrame:
CMyChildView cView;
cView.PostMessage(WM_MY_MESSAGE, 0, 0)
The code above does not work in doc/view.
I am using the same technique that Promises did. I am not sure if that is the prefer technique in the doc/view architecture. Please mention I should send the message directly from the dialog box to CChildView and how.
Thanks,
Kuphryn

My win32 program is exiting with code 3 (0x3). It seems to run fine, and last week (before I made numerous changes to the application) it was exiting with code 0. My program returns the wParam from a WM_QUIT message. I have dug through the VC++ documentation and came up dry. The only thing that I found was that WinMain (or the wParam value from WM_QUIT) is supposed to exit with 0 on success. Can someone help me decipher what exit code 3 means?
