FloodFill
The FloodFill function fills an area of the display surface with the current brush. The
area is assumed to be bounded as specified by the crFill parameter.
The FloodFill function is included only for compatibility with earlier versions of Windows.
For Win32-based applications, use the ExtFloodFill function with FLOODFILLBORDER specified.
BOOL FloodFill(
HDC hdc,
| // handle to device context
| int nXStart,
| // x-coordinate, where fill begins
| int nYStart,
| // y-coordinate, where fill begins
| COLORREF crFill
| // fill color
| );
|
|
Parameters
hdc
Identifies a device context.
nXStart
Specifies the logical x-coordinate of the point where filling is to begin.
nYStart
Specifies the logical y-coordinate of the point where filling is to begin.
crFill
Specifies the color of the boundary or of the area to be filled.
Return Values
If the function succeeds, the return value is nonzero.
If the function fails, the return value is zero. To get extended error
information, call GetLastError.
Remarks
Following are reasons this function might fail:
- The fill could not be completed.
- The given point has the boundary color specified by the crFill parameter.

Nostalgia .Net |

.Net is powerful, but not all-powerful, so sometimes we need to use Win32 API for our .Net applications. It's simple enough with Platform Invoke if you have Win32 skill, but we do not always have time to dig the ancient documentation, declare the special types that are compatible with Win32, find the values of the Win32's constants and so on. Nostalgia .Net offers several simple-to-use classes, and components that will allow you to forget about the headache of Win32 and just use the power of Win32 in your application the same way as you use the native. Net classes. More » |
