CREDUI_INFOA structure (wincred.h)

  • Article

The CREDUI_INFO structure is used to pass information to the CredUIPromptForCredentials function that creates a dialog box used to obtain credentials information.

Syntax

typedef struct _CREDUI_INFOA {
  DWORD   cbSize;
  HWND    hwndParent;
  PCSTR   pszMessageText;
  PCSTR   pszCaptionText;
  HBITMAP hbmBanner;
} CREDUI_INFOA, *PCREDUI_INFOA;

Members

cbSize

Set to the size of the CREDUI_INFO structure.

hwndParent

Specifies the handle to the parent window of the dialog box. The dialog box is modal with respect to the parent window. If this member is NULL, the desktop is the parent window of the dialog box.

pszMessageText

Pointer to a string containing a brief message to display in the dialog box. The length of this string should not exceed CREDUI_MAX_MESSAGE_LENGTH.

pszCaptionText

Pointer to a string containing the title for the dialog box. The length of this string should not exceed CREDUI_MAX_CAPTION_LENGTH.

hbmBanner

Bitmap to display in the dialog box. If this member is NULL, a default bitmap is used. The bitmap size is limited to 320x60 pixels.

Remarks

Note

The wincred.h header defines CREDUI_INFO as an alias that automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant. Mixing usage of the encoding-neutral alias with code that is not encoding-neutral can lead to mismatches that result in compilation or runtime errors. For more information, see Conventions for Function Prototypes.
