HRESULT SetColorScheme(
LOGPALETTE *pLogpal
| //Pointer to a structure
| );
|
|
Parameter
pLogpal
[in] Points to a LOGPALETTE structure that specifies the recommended palette.
Return Values
S_OK
Color palette received successfully.
E_NOTIMPL
Object does not support setting palettes.
OLE_E_PALETTE
Invalid LOGPALETTE structure pointed to by lpLogPal.
OLE_E_NOTRUNNING
Object must be running to perform this operation.
Comments
The IOleObject::SetColorScheme method sends the container application's recommended color palette to the
object application, which is not obliged to use it.
Notes to Implementors
Upon receiving the palette, the object application should:
- Allocate and fill in its own LOGPALETTE structure with the colors specified in the container application's LOGPALETTE structure.
- Call CreatePalette to create a palette from the resulting LOGPALETTE structure. This palette can be used to render objects and color menus as the
user edits objects in the document.
The first palette entry in the LOGPALETTE structure specifies the foreground color recommended by the container. The
second palette entry specifies the recommended background color. The first half
of the remaining palette entries are fill colors and the second half are colors
for the lines and text.
Container applications typically specify an even number of palette entries. If
a container specifies an odd number of entries, the object application should
assume that the first half of the total entries plus one designate fill colors,
while the remainder designate line and text colors. For example, if there are
five entries, the first three should be interpreted as fill colors and the last
two as line and text colors.

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 » |
