Yeah it's happening here too. It's international Smile | :)

.

But second time the button has focus it's working. Press tab and remove focus and then press Shift+Tab to shift back the focus. Now enter will work.
(Not the solution;P)

CAsyncSocket

I derived a class from CAsyncSocket;
if i want to send data,
shall i use AsyncSelect(FD_WRITE) and send data in virtual function OnSend(int nErrorCode);
Or use Send(const void* lpBuf,int nBufLen,int nFlags = 0) directly Confused | :confused:

if you want ASync send then AsyncSelect(FD_WRITE) (only once)
followed by many Send to send as many data, if you dont want ASync Data Sending then AsyncSelect(FD_WRITE) is not required.

MSDN has very good doc on this, you should read that first.

Handle the EN_CHANGE message sent by the editbox to it's parent window. Send a WM_GETTEXTLENGTH message to the editbox to check how many characters are in it.

I think you want to display a message box right?

So you can use EN_CHANGE handler for this purpose. And use GetWindowText(...)
to count the number of chars in the edit.

But this won't prevent the user from furthur inserting any chars in the edit.

But you can prevent this by subclassing the edit and handling WM_CHAR message. If the count in less than 3 then fine call the base class handler or else don't call it instead display a message box. This will prevent the user from inserting further chars.

Hope this is what you want.

I'll assume you are using MFC, so if so you just need to write a function on the edit boxes EN_CHANGE event. The code insode the function would be something like this

{
// m_EditText is the CString that stores the edit text(whatever you called it)

if (strlen(m_EditText) > 3)
{
// Use other message box function and add correct handle if you know it
MessageBox(NULL, "My Text is to long", "Message Caption", 0);
}

}

I believe there are functions to get the size directly from the edit box in MFC but I don't like MFC so I tend to avoid it where possible.

What I wanted was moving the focus of my keyboard to another place as soon as the number of charactors in the editbox reaches 3.
And I think what you told me can solve my problem.
Thanks a lot!

Hmm didn't get you.

You can use GradientFill function for this purpose.

To redraw background on size change just handle WM_ERASEBKGND and return TRUE to indicate to the application that you have done the background drawing.

thanks for your Reply.

1.i try in OnSize() used SetWindowRgn(),right? have other idea? my mean is the windows is small and SetWindowRgn it is small round, and the window is big SetWindowRgn it is big round.

2.Some time ago, i tried your method but when the window size change big, the background is confusion, the old background(1) still exist, other area redraw ok.

old size
|--------|-------|
|　　1　　|　　　　|
|--------|　　　　|
|　　　　　　　　　|
|　　background　|
|---------------| now size

BTW:i say the window can change the size , mean is the window flags had WS_MAXIMIZEBOX and WS_THICKFRAME

My english so bad, shame.

Yeah it happens because the visible portion need not be painted again.

Try using CClientDC. This way you can paint the entire region.
