Create buttons on heap for this purpose.

CButton *pBtns = new CButton[nNumOfPorts];
pBtns[0].Create(....using radio button style);
pBtns[1].Create(....using radio button style);
pBtns[nNumOfPorts-1].Create(....using radio button style);

That is wrong.

I suggest you to suggest him ( Roll eyes | :rolleyes:

In the same way as you would any other button, just use the BS_RADIOBUTTON style.

Please confirm whether 'if' could be placed inside a switch statement.

I'm not new to C++ OMG | :OMG:

. Today I had to write some code which includes swith cases, but case lables are valid in only some conditions (depending on the device type). I was not completly sure that the code is invalid, and wrote a test pgm in vs2k3, and it worked fine. Before checking in, wanted a confirmation.

Yes. But compile the following code and you'll know how much the compiler 'cares' about the IF statement.

int i=4;
switch(i)
{
  if(false) //Whaaa?!
  {
     case 4:
    AfxMessageBox("Whack my head with that oldskool keyboard");
            break;
  }
}

Is it the encrypted version of some nice piece of code?
Smile | :)

BTW on my system (VS2005) it compiles, but at runtime the switch condition overrides (breaks Roll eyes | :rolleyes:

) the if one: is it what you're expecting?

yeah, it was encrypted with 128bit RSA algo. Its great that you could decrypt it Smile | :)

.Just kidding..

Its neither encrypted nor a question from an interview. I had to write some code today and I re written the code in different way also. But I gor a doubt if this code is valid and wanted a confirmation.

The code compiles. But I doubt it works as you expect (i.e. avoid such misleading constructs).

Use SQL queries to edit/modify/delete/update your textbox values. you have to update your database through SQL UPDATE statement. Like:

<br />
UPDATE table<br />
SET column = expression<br />

You can use the GetWindowText() function or send a WM_GETTEXT message to the controls.

I'm not sure what you're looking for here...

If you have the data from a field of a record from the database, then
copy that data as text to the edit control.
