OLEUICHANGESOURCE structure

Contains information that is used to initialize the standard Change Source dialog box. It allows the user to modify the destination or source of a link. This may simply entail selecting a different file name for the link, or possibly changing the item reference within the file, for example, changing the destination range of cells within the spreadsheet that the link is to.

Members

cbStruct

The size of the structure, in bytes.

dwFlags

On input, this field specifies the initialization and creation flags. On exit, it specifies the user's choices. It may be a combination of the following flags.

ValueMeaning
CSF_SHOWHELP

Enables or shows the Help button.

CSF_VALIDSOURCE

Indicates that the link was validated.

CSF_ONLYGETSOURCE

Disables automatic validation of the link source when the user presses OK. If you specify this flag, you should validate the source when the dialog box returns OK.

 

hWndOwner

The window that owns the dialog box.

lpszCaption

Pointer to a string to be used as the title of the dialog box. If NULL, then the library uses Change Source.

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 nonzero 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 OLEUICHANGEICON 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 lpszTemplate member. This member is ignored if the lpszTemplate member is NULL or invalid.

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 Convert dialog box template.

hResource

Resource handle for a custom dialog box. If this member is NULL, then the library uses the standard Convert dialog box template, or if it is valid, the template named by the lpszTemplate member.

lpOFN

Pointer to the OPENFILENAME structure, which contains information used by the operating system to initialize the system-defined Open or Save As dialog boxes.

dwReserved1

This member is reserved.

lpOleUILinkContainer

Pointer to the container's implementation of the IOleUILinkContainer interface, used to validate the link source. The Edit Links dialog box uses this to allow the container to manipulate its links.

dwLink

Container-defined unique link identifier used to validate link sources. Used by lpOleUILinkContainer.

lpszDisplayName

Pointer to the complete source display name.

nFileLength

File moniker portion of lpszDisplayName.

lpszFrom

Pointer to the prefix of the source that was changed from.

lpszTo

Pointer to the prefix of the source to be changed to.
