I had known I must use the API:DoDragDrop(). But I don't know how to implement the interface of IDataObject and IDropSource. Would u be kind to give me some advice? The context of this calling of DoDragDrop is in a Dialog. So whether I must add declerations of IDataObject and IDropSource in the header file as I do in C#? I need some help. Thx!

some times ago (I think two years ago) I had this problem I wanted to have a preview before print so I explain for you but before it(you can also use of printer driver if you dont have a real printer or dont access to it see this thread[^] ) I calculate dimension for pages like A4,A3,... and convert to screen and then use of a handle to display device context (hdc) sent my datas with BitBlt to screen and it worked and finaly sent my datas to printer like this
PRINTDLG pd;
...
m_Image.BitBlt(pd.hDC,100,134,640,480,0,0,SRCCOPY);

You just blew him away by ten orders of magnitude. Explanations have to be on the fringe of insanely easy for him to bother grasping it. Anything beyond that, and you'll receive his standard, "How I do that?" rely.

Hi Guys,
I am facing a little difficulty in finding the width of a character in Vista machine.
For the same character (say 'a'),I am getting different (A,B,C values in Vista machine ,when comapare to other O S machines).
Can somebody tell me,why this is happening?
Is this a microsoft bug??
If not ,what is the FIX for it.
Please help me.
Thanks in advance.

Are you comparing the same things? Doesn't Vista use a different system font? Try selecting the same font into the DC before calling GetCharABCWidths().
|

I am using the same System Font, i.e, Tahoma 10 on all machines.
We are getting different values for A and C(underhangs and overhangs)in Vista,when compared to other Operating System.
Because of this our logic is not working in Vista.
Please help me out.

When you create the font, are you specifying the exact font or using the stock SYSTEM_FONT?

How to detect which key has been pressed along with ctrl key?
Thankyou
|
|
|
|

Use GetKeyState to find out state of control key...
BOOL SomeDialog::PreTranslateMessage(MSG* pMsg)
{
if( pMsg->message == WM_KEYDOWN &&
pMsg->wParam == VK_TAB &&
( GetKeyState( VK_CONTROL ) & 0x8000 )
)
{
HandleCtrlTab();
return TRUE;
}
return CDialog::PreTranslateMessage(pMsg);
}
