Your Data Exchange handler function might not be set up correctly.
The Data Exchange might be overwriting the data in your edit field controls, or no member variables are setup to write into the controls.
It looks like you fill them in OnInitDialog, but you should do that in DoDataExchange.

You should be able to do all your data sets and retrievals within the DoDataExchange
similar to something like this:
void Cfirstw32mfcDlg::DoDataExchange(CDataExchange* pDX)
{
CDHtmlDialog::DoDataExchange(pDX);
// data TO controls, means LOAD strings with your existing data or default values
// you need to do this BEFORE the DDX_DHtml_ElementInnerText calls
if( !pDX->m_bSaveAndValidate ){
EDIT1 = AfxGetApp()->GetProfileString("Settings", "email", "your login");
EDIT2 = AfxGetApp()->GetProfileString("Settings", "password", "details here..");
}
// these calls presumably set or get the data from the controls into your string variables
DDX_DHtml_ElementInnerText(pDX, _T("email"), EDIT1);
DDX_DHtml_ElementInnerText(pDX, _T("password"), EDIT2);
DDX_DHtml_ElementInnerText(pDX, _T("Temp_Text1"), m_EDIT1);
DDX_DHtml_ElementInnerText(pDX, _T("Temp_Text2"), m_EDIT2);
// data FROM controls, means SAVE data from the controls to your storage
// you need to do this AFTER the DDX_DHtml_ElementInnerText calls
if( pDX->m_bSaveAndValidate ){
GetElementText(_T("email"));
AfxGetApp()->WriteProfileString("Settings", "email", EDIT1);
GetElementText(_T("password"));
AfxGetApp()->WriteProfileString("Settings", "password", EDIT2);
}
}
If the DoDataExchange is correctly implemented, you don't even need to have the OnOK handler, since the DoDataExchange will be called for you (I am pretty sure) and you definitely don't need the Cancel, because the UpdatData (and thus DoDataExchange) is not called at all.

How do you determine the column on a listCtrl when you say double-click on the list.
I use the following to find the row:-
POSITION p = m_cAList.GetFirstSelectedItemPosition ();<br />
int row = m_cAList.GetNextSelectedItem (p);
I did think the use GetSelectedColumn() but GetSelectedColumn() gives the error:-
c:\C_Example\GenericDlg.cpp(602): error C2039: 'GetSelectedColumn' : is not a member of 'CListCtrl'
I have the listCtrl setup as a table with grid lines on and was going to use:-
int col = m_cAList.GetSelectedColumn();<br />
int index = (row * 16) + col;
To obtain the position in the table.
Help?!?

Do you have a handler for the NM_DBLCLK message? If so, look at the iItem and iSubItem members of the NMITEMACTIVATE structure that is sent to the handler function.

Getting a bit lost here, Yes do have a handler for the double-click on the listCtrl:-
void CGenericDlg::OnNMDblclkList(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
<br />
POSITION p = m_cAList.GetFirstSelectedItemPosition ();<br />
m_cAList.GetNextSelectedItem (p);<br />
int row = m_cAList.GetNextSelectedItem (p);
Just wanted to know how to get the column here.
But if I now do (I think this is what you suggested)
NMITEMACTIVATE *lpnmitem = (LPNMITEMACTIVATE) pNMHDR;<br />
<br />
int col = lpnmitem->iSubItem;<br />
<br />
int row = lpnmitem->iItem;
Here the col is OK but the row is always set to -1.

ASAIK, you cannot find both row and column this directly. Use GetNextSelectedItem to retrieve the selected item index (the 'row') and the pNMHDR to retrieve the 'column' (as you did in your second method).
As for
sweep123 wrote:
Here the col is OK but the row is always set to -1.
-1 is the normal return value if you consider a subitem (see MSDN:
iItem Index of the list view item. If the item index is not used for the notification, this member will contain -1.)
-> you can only get information about one item _OR_ one subitem. Your list ctrl is not a grid, it is indeed a list.

I did manage to get the row and col of a list control by putting the option LVS_EX_FULLROWSELECT on for the list control, but it looks a little messy with one whole row selected. When I turn this setting off I aways get -1 for the row (item) and thats with GetNextSelectedItem() and pNMHDR methods.
I dont know a better way to get both the row and col of a list control.
I am sure someone will know of a neater solution.

Are you using CreateWindow()? Try using WS_POPUP | WS_VISIBLE as the third parameter.

Hey Friends
I have created an application which dials out a number and plays a .wav file.Now i need to test the application but on my current premises, I do not have a Phone Line.
Is there any way by which i can test my application without Phone Line and Modem ?

You can use one of these.
www.teltone.com
http://www.teltone.com/products/simulators/tls3/home.htm
Teltone's TLS-3B is an inexpensive simulator that makes it easy to perform basic feature and performance testing of telecommunications equipment including:
Telephones
Modems
Faxes
Caller ID equipment
Anything that connects to a phone line!
The TLS-3B is Teltone's lowest-cost unit. You plug in a phone to one of the two ports, and you will think you are connected to the phone company! Dial the default or programmed phone number, and the other line will ring. It's like having a miniature public telephone network in a box.
The TLS-3B has programmable functions which allow you to configure features like caller ID, test tones, and hot line ringdown.
That's what I used to do.

I have created 2 sockets .
I fr my server application <192.168.2.20> port 80
I fr my client. IP Address assigned: 192.168.0.51 port 80
Both The applications reside on the same machine.
When I execute the server it runs fine
But when I run the Client , it shows error code : 10047
Yeah, After surfing the net I got to know that Protocol family not supported ...
But the problem iz........
Unless the Connection is not established between the two applications
how come it give such error.
What Can there be other possibilities?
The portion causing error is Enclosed.

Seems you are trying to bind the client socket also at port 80 which is not necessary .You can not bind two sockets on a same port ( exceptions are there but you wont need it )
So do this way ...Create a server socket , bind it to port 80 of you IP and make it listen for incomin connections . Next create a client socket . *Dont* bind it toany port (or bind it to non-80 port ) and connect toserver at 80 ...

Thnx fr guiding me . This being my fst attempt in socket prg.
Yeah i cud move ahead all bcoz of u , but caught again midway.
In my server program when i use recv() it gives the failed to bind and failed to listen errors. When i m trying to print the acceptance after the accept function it shows the connection. That <client ip="" address="" is="" connected="">
On other side When i use recv fn in Client application some garbage is printed in . I use it like
<br />
{<br />
<br />
char buff[512];<br />
servAddrSrvr.sin_addr.s_addr=inet_addr("192.168.0.20");<br />
servAddrSrvr.sin_family=AF_INET;<br />
servAddrSrvr.sin_port=htons(80);<br />
connect(conn,(struct sockaddr*)&servAddrSrvr,sizeof(servAddrSrvr));<br />
recv(conn,buff,sizeof(buff),0);<br />
printf("%s\n",buff);<br />
}<br />
Can u say me where i went wrong.

You're ignoring the length of received data (returned by recv()), you're not checking if all data is read in a single call to recv() and you're assuming that the data placed in buf by recv() is zero-terminated.

I would suggest CFile for this.

This is limited information, but my first inclination would be to use strtoul(). This assumes you would be reading the data in as a string.

Hi world,
I'm want limiting a folder size. My application create some files inside this folder but I don't want exceed the desired size. Thus this application must delete older files when I want to add new file (to always respect the size limitation).
