Which part of Win32API?

Is there any subset of Win32API that is capable of dealing with TrueType Fonts like picking up a Glyph from the TrueType and rasterizing it.... (While the font is'nt installed in Fonts folder)

Please let me know...

See AddFontResourceEx( , R_PRIVATE, ) to load a font from a file into the application space.

Once the font is added to the application space you can get a font handle just like you would for a system font, load it into a DC (bitmap), and then write the required text to the DC.

...cmk

TrueType Fonts is new in the .NET Framework version 2.0.

So use the following namespace to get that,

System.Windows.Forms.VisualStyles Namespace

I guess your ListBox items are getting sorted. Disable sorting and check.

		m_SOUT.AddString(buff);

	}
}

As well use proper indentation, so that others can understand your code. Smile | :)

I have not tested the code, hope this works

Handle WM_SIZE message in View and use SetWindowPos or MoveWindow api to change size of the ListCtrl accordingly.

Create a hatched bit pattern

the following is the code I found in MSDN.
Anybody can explain about the hatchbits? I didnt get anything from the code.

See the code below

// Create a hatched bit pattern.
WORD HatchBits[8] = { 0x11, 0x22, 0x44, 0x88, 0x11,
0x22, 0x44, 0x88 };

// Use the bit pattern to create a bitmap.
CBitmap bm;
bm.CreateBitmap(8,8,1,1, HatchBits);

// Create a pattern brush from the bitmap.
CBrush brush;
brush.CreatePatternBrush(&bm);

// Select the brush into a device context, and draw.
CBrush* pOldBrush = (CBrush*)pDC->SelectObject(&brush);
pDC->RoundRect(CRect(50, 50, 200, 200), CPoint(10,10));

// Restore the original brush.
pDC->SelectObject(pOldBrush);
