Please use the following code if u can use MFC.
UINT BITS_IN_A_BYTE = 8;
CBitmap BlankBmp;
BYTE *pbyBits = 0;
SIZE_T nBits;
nBits = m_uImgWidth * m_uImgHeight;
pbyBits = new BYTE[nBits + UNITY];
if( 0 == pbyBits )
{
return;
}
// Fill it with Black RGB values (R=0, G=0, B=0)
ZeroMemory( pbyBits, nBits + UNITY );
BlankBmp.CreateBitmap( m_uImgWidth, m_uImgHeight,
1, BITS_IN_A_BYTE, pbyBits );
delete[] pbyBits;

Using Win32 APIs or MFC? Do you want a DIB, DDB, or a DIB section?

Hi,
use "WTSRegisterSessionNotification()" to register your window to receive
the notification "WM_WTSSESSION_CHANGE" which has "WTS_SESSION_LOCK" & "WTS_SESSION_UNLOCK" parameter to identify that.
Best Regards

Implement the ISensLogon interface. The DisplayLock() and DisplayUnLock() methods are of interest to you.

Hi,
I have a List control and I have to change the border color of it dynamically such as, on mouse hover, on focus etc. So I handled the WM_NCPAINT and draw the border with my own color. But when I have to change the color, how will I invoke the WM_NCPAINT. Can I send that message directly? Or is there any other functions that invokes this message indireclty?
N.B - I need to paint only the non client area.
Thanks

If you're using MFC try something like this:
m_ctl.RedrawWindow(NULL, NULL, RDW_ERASE|RDW_FRAME|RDW_INVALIDATE|RDW_UPDATENOW);
For raw Win32:
RedrawWindow(m_hWnd, NULL, NULL, RDW_ERASE|RDW_FRAME|RDW_INVALIDATE|RDW_UPDATENOW);

But in this case paint message is also generated. I want to invoke only the WM_NCPAINT message.

Call SetWindowPos with SWP_DRAWFRAME.

Is there a clean way to convert a #define constant like '#define MYNUM 3' to a long string for a parameter like 'SetDlgItemText (hDlg, IDC_EDIT1, MYNUM) ;'
Thanks!

you'd have to use sprintf or something, just the same as if you had the number 3 inline. Which in fact you do, the preprocessor replaces MYNUM with 3.

Hello Gentlemen,
I have another problem with the same project I was talking about in an earlier post.
This time my error is error C2228: left of '.current_energy' must have class/struct/union.
The code in question is...
caster.Creatures[i].current_energy = nrg[i];
I realize that Creatures[i] indicates a pointer, not an array, however I don't quite understand how to rewrite it to access that curren_energy data that I require at this point.
Any help would be much appreciated.
Thank you.
