hi,

i have a dialog box in which i have dragged dropped a edit box control.
i have validated the editbox control by creating a class called validate and the base class of it to be CEDIT class.

i have wriiten the code for validation in onkeyup method of validate class

i have declared the variable of the editbox control to be of the type validate.it works fine

the code for validation is as follows:

<br />
void hi::OnKeyUp(UINT nChar, UINT nRepCnt, UINT nFlags) <br />
{<br />
<br />
	if (nChar <=57 && nChar >=48)<br />
		AfxMessageBox("hi");<br />
	else<br />
		AfxMessageBox("hello");<br />
		return;<br />
}<br />

when i nter alphabets i get a message box and then i need to clear the character entered how to do this???

thnx in advance,

zari

Hi,

you can use CEDIT Member function..

CEdit* pmyEdit;

// Delete all of the text.
pmyEdit->SetSel(0, -1);
pmyEdit->Clear();

Kind Regards,
Priya.

You get message box in all cases.

If you want to perform validations, use PreTranslateMessage of you CEdit derived class instead.

BOOL CMyEdit::PreTranslateMessage(MSG* pMsg) 
{
	if ( pMsg->message == WM_CHAR)
	{
	     UINT nChar = (UINT) pMsg->wParam;
             if ( nChar <=57 && nChar >=48 )
	     {
                 return TRUE;//char will not be entered
             }
	}
	return CEdit::PreTranslateMessage(pMsg);
}

Is that a dialog based app or MDI or SDI app? Or is that not using MFC? There is a feature called debug. You must try that.

Start debugging from InitDialog and edit what you want.

Hi all,

i have one problem related to thread. i am having my main thread running which will
on some event create a thread for validation purpose and then will start working.
and now this validator thread will create a socket and it will bind to port 20111.
and then will wait for client to connect.

but before waiting for client to connect it will send a message to the main thread that
validation is done.

but in this way i need to stick with port 20111.which i really don't want.
Is it possible for me to get a free port from operating system or from winsock
library and then i should bind to this port??
and one more thing i want is i want to get the free port no that operating system
has given in an variable because i will need that port number further in the main programs lifetime.

the code is as follows

UINT Thread_Func(LPVOID pParam)
{
wsaret = WSAStartup(0x101,&wsadata);
if(wsaret != 0)
return -1;

sock.sin_family = AF_INET;
sock.sin_addr.s_addr = INADDR_ANY;
sock.sin_port = htons((unsigned short)20111);// iwant to obtain this port no on fly and
// to get it in some variable so that i can use it further in my main thread

server = socket(AF_INET,SOCK_STREAM,0);
if(server == INVALID_SOCKET)
return -1;

if(bind(server,(SOCKADDR *)&sock,sizeof(sock))!=0)
return -1;
if(listen(server,1)!=0)
return -1;

cli_len = sizeof(cli);
client = accept(server,(SOCKADDR *)&cli,&cli_len);
if(client == 0)
return -1;

return 1;
}

i have not done socket programming before this is my first time i am doing it
so if there are any mistakes please let me know

Thanks and regards

something in the back of my brain said: "sock.sin_port = 0" would let the OS select the port....

yes that is true but how i can access that port number??

Re: Socket prblem

spielehelfer6-Dec-06 4:51

maybe you can reverse use the sock.sin_port after the connection has been occured with
port = ntohs(sock.sin_port) from the socket.

How can I interface with MS-Word

I want to write a program that makes MS-Word open a doc file, make some changes to it and then save it.

I don't want to open the entire word GUI every time I do this, how can I interface with Word in such a way?

How do you want to do it?

Through a direct query (SQL "UPDATE") or through a recordset?

Do you have the text from the edit control?

What have you tried?
