GetClipboardData
The GetClipboardData function retrieves data from the clipboard in a specified format. The
clipboard must have been opened previously.
HANDLE GetClipboardData(
UINT uFormat
| // clipboard format
| );
|
|
Parameters
uFormat
Specifies a clipboard format. For a description of the clipboard formats, see
the SetClipboardData function.
Return Values
If the function succeeds, the return value is the handle of a clipboard object
in the specified format.
If the function fails, the return value is NULL. To get extended error
information, call GetLastError.
Remarks
An application can enumerate the available formats in advance by using the EnumClipboardFormats function.
The clipboard controls the handle that the GetClipboardData function returns, not the application. The application should copy the data
immediately. The application cannot rely on being able to make long-term use of
the handle. The application must not free the handle nor leave it locked.
The operating system performs implicit data format conversions between certain
clipboard formats when an application calls the GetClipboardData function. For example, if the CF_OEMTEXT format is on the clipboard, a window
can retrieve data in the CF_TEXT format. The format on the clipboard is
converted to the requested format on demand. The following table shows the clipboard
data type conversions that are available. Note that some of these automatic
type conversions are not available on all platforms.

If the operating system provides an automatic type conversion for a particular
clipboard format, there is no advantage to placing the conversion format(s) on
the clipboard.
If the system provides an automatic type conversion for a particular clipboard
format, and you call EnumClipboardFormats to enumerate the clipboard data formats, the operating system first
enumerates the format that is on the clipboard, followed by the formats to which it can
be converted.
If the clipboard contains data in the CF_PALETTE format, the application
should use the SelectPalette and RealizePalette functions to realize any other data in the clipboard against that logical
palette.
See SetClipboardData for further information on specific clipboard data formats.

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 » |
