From the MSDN:
&& (and)
&= (and_eq)
& (bitand)
| (bitor)
~ (compl)
! (not)
!= (not_eq)
|| (or)
|= (or_eq)
^ (xor)
^= (xor_eq)

how to draw bitmap using CDC
Ashish
|
|
|
|
|
You can use of this code on the paint event or earse event(I didnt test but I think it works).
#include "Atlimage.h"
CImage m;
m.Load(_T("c:\\1.jpg"));
m.BitBlt(0,0,800,600);

So see Displaying Bitmap with Scrolling[^].

Check out this article - Displaying a Bitmap from a BMP File[^]. If you don't want to display the file, then just skip that part and refer the drawing part only.

Array size must be specified!

What about documentation [^]?

DWORD GetMessagePos(void);
This function returns a long value that gives the cursor position in screen coordinates.
How to get X and y coordinates.
|
|
|
|
|
Use GET_X_LPARAM and GET_Y_LPARAM.
const DWORD Pos = GetMessagePos();
const short XPos = GET_X_LPARAM(Pos);
const short YPos = GET_Y_LPARAM(Pos);
Another alternative is to use MAKEPOINTS structure, depends on if you want your pos wrapped in a POINT struct.

CPoint point = CPoint(GetMessagePos());

Or use LOWORD and HIWORD macro instead, like this
DWORD dwPos = ::GetMessagePos ();
CPoint point (LOWORD (dwPos), HIWORD (dwPos));
|
|
|
|
|
Do not use LOWORD and HIWORD. Coordinates are signed values, LO/HIWORD treat the parameter as unsigned.

Hi All,
Could anyone tell me where to put the code for initialization for a new added dialog box in MFC application?
The InitInstance() is available only for the main window, inside which we can write code for initialization.But my problem is , where to write the code for a newly created dialog (if i want to do something when the dialog gets loaded)
Than u in advance

The right place is OnInitDialog [^].

In MFC for every dialog there must be a class that's generated by the class wizard. Also it generates a function for this class called OnInitDialog, this function is called after the dialog and it's controls are created but not bound to data exchange member variables, which will be done when we call CDialog::OnInitDialog from our OnInitDialog.
There must be a comment in your OnInitDialog function which says
// Add your initialization code here
So after this call you can add your code for intialization.
