No code example is currently available or this language may not be supported.
| Invalidate |
1 |
Invalidates the rectangle or region that you specify in lprcUpdate or hrgnUpdate parameters.
You can set only one of these parameters to a non-Zero value.
If both are Zero, Invalidate invalidates the entire window.
|
| InternalPaint |
2 |
Causes the OS to post a WM_Paint message to the window
regardless of whether a portion of the window is invalid.
|
| Erase |
4 |
Causes the window to receive a WM_EraseBkgnd message when the window is repainted.
Specify this value in combination with the Invalidate value;
otherwise, Erase has no effect.
|
| Validate |
8 |
Validates the rectangle or region that you specify in lprcUpdate or hrgnUpdate parameters.
You can set only one of these parameters to a non-Zero value.
If both are Zero, Validate validates the entire window.
This value does not affect internal WM_Paint messages.
|
| NoInternalPaint |
16 |
Suppresses any pending internal WM_Paint messages.
This flag does not affect WM_Paint messages resulting from a non-NULL update area.
|
| NoErase |
32 |
Suppresses any pending WM_EraseBkgnd messages.
|
| NoChildren |
64 |
Excludes child windows, if any, from the repainting operation.
|
| AllChildren |
128 |
Includes child windows, if any, in the repainting operation.
|
| UpdateNow |
256 |
Causes the affected windows,
which you specify by setting the AllChildren
and NoChildren values,
to receive WM_EraseBkgnd and WM_Paint messages
before the RedrawWindow returns, if necessary.
|
| EraseNow |
512 |
Causes the affected windows,
which you specify by setting the AllChildren
and NoChildren values,
to receive WM_EraseBkgnd messages
before RedrawWindow(IntPtr, NativeRectangle, IntPtr, RedrawWindowFlags) returns, if necessary.
The affected windows receive WM_Paint messages at the ordinary time.
|
| Frame |
1,024 |
Causes any part of the non-client area of the window that intersects the update region
to receive a WM_NcPaint message.
The Invalidate flag must also be specified;
otherwise, Frame has no effect.
The WM_NcPaint message is typically not sent during the
execution of RedrawWindow(IntPtr, NativeRectangle, IntPtr, RedrawWindowFlags) unless
either UpdateNow or EraseNow is specified.
|
| NoFrame |
2,048 |
Suppresses any pending WM_NcPaint messages.
This flag must be used with Validate
and is typically used with NoChildren.
NoFrame should be used with care,
as it could cause parts of a window to be painted improperly.
