# OLEUIPASTESPECIAL

The OLEUIPASTESPECIAL structure contains information that the OLE User Interface Library uses to initialize the Paste Special dialog box, as well as space for the library to return information when the dialog box is dismissed.

Members

cbStruct
  Size of the structure, in bytes. This field must be filled on input.
dwFlags
  On input, dwFlags specifies the initialization and creation flags. On exit, it specifies the user’s choices. It may be a combination of the following flags:
  PSF_SHOWHELP
    Dialog box will display a Help button.
  PSF_SELECTPASTE
    The Paste radio button will be selected at dialog box startup. This is the default, if PSF_SELECTPASTE or PSF_SELECTPASTELINK are not specified. Also, it specifies the state of the button on dialog termination. IN/OUT flag.
  PSF_SELECTPASTELINK
    The PasteLink radio button will be selected at dialog box startup. Also, specifies the state of the button on dialog termination. IN/OUT flag.
  PSF_CHECKDISPLAYASICON
    Whether the Display As Icon radio button was checked on dialog box termination. OUT flag.
  PSF_DISABLEDISPLAYASICON
    The Display As Icon check box will be disabled on initialization.
  HIDECHANGEICON
    Used to disable the change-icon button in the dialog box , which is available to users when they’re pasting an OLE object by default. See STAYONCLIPBOARDCHANGE otherwise.
  STAYONCLIPBOARDCHANGE
    Used to tell the dialog box to stay up if the clipboard changes while the dialog box is up. If the user switches to another application and copies or cuts something, the dialog box will, by default, perform a cancel operation, which will remove the dialog box since the options it’s in the middle of presenting to the user are no longer up-to-date with respect to what’s really on the clipboard.
  NOREFRESHDATAOBJECT
    Used in conjunction with STAYONCLIPBOARDCHANGE (it doesn’t do anything otherwise). If the clipboard changes while the dialog box is up and STAYONCLIPBOARDCHANGE is specified, then NOREFRESHDATAOBJECT indicates that the dialog box should NOT refresh the contents of the dialog box to reflect the new contents of the clipboard. This is useful if the application is using the paste-special dialog box on an IDataObject besides the one on the clipboard, for example, as part of a right-click drag-and-drop operation.
hWndOwner
  Wwindow that owns the dialog box. It should not be NULL.
lpszCaption
  Pointer to a string to be used as the title of the dialog box. If NULL, then the library uses Paste Special.
lpfnHook
  Pointer to a hook function that processes messages intended for the dialog box. The hook function must return zero to pass a message that it didn’t process back to the dialog box procedure in the library. The hook function must return a non-zero value to prevent the library’s dialog box procedure from processing a message it has already processed.
lCustData
  Application-defined data that the library passes to the hook function pointed to by the lpfnHook member. The library passes a pointer to the OLEUIPASTESPECIAL structure in the lParam parameter of the WM_INITDIALOG message; this pointer can be used to retrieve the lCustData member.
hInstance
  Instance that contains a dialog box template specified by the lpTemplateName member.
lpszTemplate
  Pointer to a null-terminated string that specifies the name of the resource file for the dialog box template that is to be substituted for the library’s Paste Special dialog box template.
hResource
  Customized template handle.
lpSrcDataObj
  Pointer to the IDataObject* interface of the data object to be pasted (from the clipboard). This field is filled on input. If lpSrcDataObj is NULL when OleUIPasteSpecial is called, then OleUIPasteSpecial will attempt to retrieve a pointer to an IDataObject from the clipboard. If OleUIPasteSpecial succeeds, it is the caller’s responsibility to free the IDataObject returned in lpSrcDataObj.
arrPasteEntries
  The OLEUIPASTEENTRY array which specifies acceptable formats. This field is filled on input.
cPasteEntries
  Number of OLEUIPASTEENTRY array entries. This field is filled on input.
arrLinkTypes
  List of link types that are acceptable. Link types are referred to using OLEUIPASTEFLAG in arrPasteEntries. This field is filled on input.
cLinkTypes
  Number of link types. This field is filled on input.
cClsidExclude
  Number of CLSIDs in lpClsidExclude. This field is filled on input.
lpClsidExclude
  Pointer to an array of CLSIDs to exclude from the list of available server objects for a Paste operation. Note that this does not affect Paste Link. An application can prevent embedding into itself by listing its own CLSID in this list. This field is filled on input.
nSelectedIndex
  Index of arrPasteEntries[] that the user selected. This field is filled on output.
fLink
  Whether Paste or Paste Link was selected by the user. This field is filled on output.
hMetaPict
  Handle to the Metafile containing the icon and icon title selected by the user. This field is filled on output.
sizel
  Size of object as displayed in its source, if the display aspect chosen by the user matches the aspect displayed in the source. If the user chooses a different aspect, then sizel.cx and sizel.cy are both set to zero. The size of the object as it is displayed in the source is retrieved from the ObjectDescriptor if fLink is FALSE and from the LinkSrcDescriptor if fLink is TRUE. This field is filled on output.
