How can we create RadioButtons at runtime
Means i have recognised the COM Ports and those i need to display as radiobuttons for User Selection but Number of COM ports may differ sooo i some assistance to how to create radiobuttons dynamically depending on data we get at runtime.
for ex we COM1 COM2 ports
now i have to get those and create radiobutons
but data may change
it can only COM1 depending on connnection

I think you can use like this for example
CButton m_Button[3];
m_Button[0].Create(_T("Port1"),WS_CHILD|BS_RADIOBUTTON|WS_VISIBLE,CRect(0,0,100,23),this,1);
...

What about a list (or combo) box?

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 ( ) the final cleanup too. Do you know, when dealing with dynamic allocation, newbies tend to forget it.

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

int i = 10;<br />
int k = 100;<br />
switch(i)<br />
{<br />
case 0:<br />
cout << "case 0" <<endl;<br />
break;<br />
if(k == 100)<br />
{<br />
case 10:<br />
cout <<"The device type is 100 so attribute 10 is valid"<<endl;<br />
break;<br />
}<br />
else<br />
{<br />
case 100:<br />
cout <<"attribute 100 is there" << endl;<br />
break;<br />
}<br />
break;<br />
default:<br />
cout <<"default"<<endl;<br />
}<br />
Please confirm whether 'if' could be placed inside a switch statement.

Is this a real question? or you are new to c++?

I'm not new to C++  . 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.

and the reason behind this doubt for not using an 'if' in a switch block is ...  !!!

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)
{
case 4:
AfxMessageBox("Whack my head with that oldskool keyboard");
break;
}
}

Rutherford would say: "the switch statement targets its case condition passing the if block like as if you fired a 15-inch shell at a piece of tissue paper"

Is it the encrypted version of some nice piece of code?
BTW on my system (VS2005) it compiles, but at runtime the switch condition overrides (breaks ) the if one: is it what you're expecting?

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

Why would you go to all the trouble of creating this post when you could have just compiled it to find out?

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 />
