Same way as we create a dialog box from any other place.

MFC:

void CMyFirstDialog::OnAButtonPressed ()
{
    CMySecondDialog dlg2 (this);
    if (dlg2.DoModal () == IDOK)
    {
        // do something interesting here.
    }
}

Not quite sure how the windows start button comes into it, other than doing something when a button is pressed.

Iain Clarke appears because ^CPallini still cares.

Same answer... Just written a bit differently.

Instead of "OnMyButton", you'll have a Dlg/Wndproc, with a

case WM_COMMAND:
...
   case IDC_MYBUTTON:
       DialogBox (hDlg, ... etc);

MFC is just nicely packaged SDK. Anyhinh it can do, you can do for yourself. The book keeping gets harder, but not the ideas.

convert an array unsigned char to a string

Hello

I need help on how to convert an array which its datatype is unsigned char to a string. The scenario is like this. I detect the mac address of a computer using GetAdaptersInfo API. So the return result of the call is the current MAC address which is available and the return Mac address is an unsigned char. So I can print the MAC address by using this code below :-

 <br />
<br />
static void showMACArray(unsigned char MACData[])<br />
{<br />
		<br />
	printf("%02X-%02X-%02X-%02X-%02X-%02X\n", <br />
		MACData[0], MACData[1], MACData[2], MACData[3], MACData[4], MACData[5]);<br />
}<br />

I want to print out as such that the Mac Data is in a string just like the code below :-

<br />
<br />
printf("The Mac address would be %s\n", MACData);<br />
<br />

I understand that i must concatenate each of the MACData[] array so that it combines together using strcat(). However, before using strcat(), i must convert each of the MACData unsigned char array to a string so that it can support the strcat() function. How can I solve this? Thank you and your help is really appreciated.

Alternatives:
- sprintf [^].
- CString::Format [^]
- Write you own converter: it is a simple programming exercise.

Isn't this kind of obvious? You'll have a caret only where there is a text-area (where you could possibly type and the letters appear). What possibly made you ask such a question?

You can use the caret in any window you want to.

Since a caret is generally used to mark an insertion point, it only really makes sense to use
it where the user can insert something.

Caret is for text and editbox is for enter the textes but I guess your intent is focus,right?
