ResizeParentToFit

This method allows the size of your view to dictate the size of its frame window. This is recommended only for views in MDI child frame windows. Use ResizeParentToFit in the OnInitialUpdate handler function of your derived view class.

ResizeParentToFit assumes that the size of the view window has been set. If the view window size has not been set when ResizeParentToFit is called, you will get an assertion. To ensure that this does not happen, make the following call before calling ResizeParentToFit:

GetParentFrame()->RecalcLayout();

Override the WM_CUT, WM_COPY and WM_PASTE handlers.

You can leave the handlers empty.

Display multi line colors in Rich edit control using VC++

I have a static control(derived from CStatic) and rich edit controls and it contains two lines. I want to set the color of the first line to blue and the second line to red. Currently I am using the CDialog::OnCtlColor and using the SetTextColor function to set the color. However it sets the color for the whole static control i.e. both the lines. Can someone help?

Hi
I have created a CButton in the following way.
CButton btnTemp;
UINT uiBtnStyle = BS_PUSHBUTTON | WS_CHILD | WS_VISIBLE | WS_TABSTOP;
btnTemp->Create(szButtonName, uiBtnStyle, rectGroups, this, IDC_TEMP);

When I have focus on the button ,enter key press on the button does not trigger the Event for the button.

Someone tell me where I must have gone wrong.

Thanks,
Gayathri.

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:

Re: CAsyncSocket

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.
