The following example creates a
StringFormat object, sets the trimming style, and uses the
StringFormat object to draw a string. The code also draws the string's layout rectangle.
C++
VOID Example_SetTrimming(HDC hdc)
{
Graphics graphics(hdc);
SolidBrush solidBrush(Color(255, 255, 0, 0));
FontFamily fontFamily(L"Times New Roman");
Font font(&fontFamily, 24, FontStyleRegular, UnitPixel);
StringFormat stringFormat;
stringFormat.SetTrimming(StringTrimmingEllipsisWord);
graphics.DrawString(
L"One two three four five six seven eight nine ten",
47, // string length
&font,
RectF(30, 30, 160, 60),
&stringFormat,
&solidBrush);
// Draw the rectangle that encloses the text.
Pen pen(Color(255, 255, 0, 0));
graphics.DrawRectangle(&pen, 30, 30, 160, 60);
}

The following illustration shows the output of the preceding code.
