The word "multi." They both imply more than one thread.

Hi All,
Can someone provide a good link that relates to the designing and development of code for creating efficient user interfaces.(Only Win32)
I tried googling for the same without any satisfactory results.
Some good articles on codeproject or some where else.

Somethings seem HARD to do, until we know how to do them.

Sometimes it difficult to define efficent. i have experienced in many cases where i have to change the efficent UI( from functional and user point of view), but customer does'nt need that UI.
I know it sound silly, but just designed what customer wants Smile | :)

Whats DigStatic CDialog and do you incldue h file and if this isnt your answer can you show your code that has error,please
I see you include #include "Digistatic.h" in digitaldlg.h
wheres class CDigistatic(i think i had like this error already)

In your .h file
you must have deleted the enum

something like this
// Dialog Data
enum { IDD = IDD_MYAPP_DIALOG };

where IDD_MYAPP_DIALOG is a dialog box template

The error came from the "DigStatic" class not from the CDigitalDlg. Plz show the header of DigStatic class

ok...but u typed DigStatic not CDigiStatic.

so the above given class is derived from the CStatic. so I think this will be the of the constructor of CDigiStatic.

plz check if the construcor of the CDigiStatic is as given below

CDigiStatic::CDigiStatic()
{
}

if u see IDD in this constructor, try removing it..or plz paste the code of the constructor.... let us check

Re: Problems in Static LED control - CDigiStatic [modified]

12-Jul-06 0:20

here is the DigStatic:

<br />
class DigitStatic : public CDialog<br />
{<br />
DECLARE_DYNAMIC(DigitStatic)<br />
<br />
public:<br />
DigitStatic(CWnd* pParent = NULL); // standard constructor<br />
virtual ~DigitStatic();<br />
<br />
// Dialog Data<br />
// enum { IDD = IDC_CUSTOM2 };<br />
<br />
protected:<br />
virtual void DoDataExchange(CDataExchange* pDX); // DDX/DDV support<br />
<br />
DECLARE_MESSAGE_MAP()<br />
};<br />

You can see there the constructor.
and here is the CDigStatic and you can see there all you want:

<br />
// CDigiStatic class<br />
<br />
class CDigiStatic : public CStatic<br />
{<br />
// Construction<br />
public:<br />
CDigiStatic();<br />
<br />
// Attributes<br />
public:<br />
enum {<br />
DS_SMOOTH = 1, // Pioneer kind of characters<br />
DS_STYLE14 = 2, // use allways 14 segment display.<br />
DS_SZ_PROP = 4, // size proportional(default)<br />
DS_NO_OFF = 8, // Don't draw the off segments<br />
DS_SOFT = 16 // ambient bleeding to background<br />
