Paste Operations

To retrieve paste information from the clipboard, a window first determines the clipboard format to retrieve. Typically, a window enumerates the available clipboard formats by using the EnumClipboardFormats function and uses the first format it recognizes. This method selects the best available format according to the priority set when the data was placed on the clipboard.

Alternatively, a window can use the GetPriorityClipboardFormat function. This function identifies the best available clipboard format according to a specified priority. A window that recognizes only one clipboard format can simply determine whether that format is available by using the IsClipboardFormatAvailable function.

After determining the clipboard format to use, a window calls the GetClipboardData function. This function returns the handle of a global memory object containing data in the specified format. A window can briefly lock the memory object in order to examine or copy the data. However, a window should not free the object or leave it locked for a long period of time.
