The following example creates a
StringFormat object, sets the string's format flags, and then gets the 32-bit value that contains the format flags and stores it in a variable. The code then creates another
StringFormat object and uses the stored format flags value to set the format flags of the second
StringFormat object. Next, the code uses the second
StringFormat object to draw a formatted string. The code also draws the string's layout rectangle.
C++
VOID Example_GetFormatFlags(HDC hdc)
{
Graphics graphics(hdc);
SolidBrush solidBrush(Color(255, 255, 0, 0));
FontFamily fontFamily(L"Times New Roman");
Font font(&fontFamily, 24, FontStyleRegular, UnitPoint);
// Create a StringFormat object, and set its format flags.
StringFormat stringFormat;
stringFormat.SetFormatFlags(
StringFormatFlagsDirectionVertical | StringFormatFlagsNoFitBlackBox);
// Get the format flags from the StringFormat object.
INT flags = stringFormat.GetFormatFlags();
// Create a second StringFormat object with the same flags.
StringFormat stringFormat2;
stringFormat2.SetFormatFlags(flags);
// Use the second StringFormat object in a call to DrawString.
graphics.DrawString(
L"This text is vertical because of a format flag.",
47, // string length
&font,
RectF(30, 30, 150, 200),
&stringFormat2,
&solidBrush);
// Draw the rectangle that encloses the text.
Pen pen(Color(255, 255, 0, 0));
graphics.DrawRectangle(&pen, 30, 30, 150, 200);
