CommDlgExtendedError

The CommDlgExtendedError function returns a common dialog box error code. This code indicates the most recent error to occur during the execution of one of the following common dialog box functions:

ChooseColor	GetOpenFileName
ChooseFont	GetSaveFileName
FindText	PrintDlg
ReplaceText	PageSetupDlg

DWORD CommDlgExtendedError(VOID)

Parameters

This function has no parameters.

Return Values

If the most recent call to a common dialog box function succeeded, the return value is undefined.

If the common dialog box function returned FALSE because the user closed or canceled the dialog box, the return value is zero. Otherwise, the return value is a nonzero error code. For more information, see the following Remarks section.

Remarks

The CommDlgExtendedError function can return general error codes for any of the common dialog box functions. In addition, there are error codes that are returned only for a specific common dialog box. The error codes returned by CommDlgExtendedError are defined in the CDERR.H file.

The following general error codes can be returned for any of the common dialog box functions:

Value	Meaning
CDERR_DIALOGFAILURE	The dialog box could not be created. The common dialog box function's call to the DialogBox function failed. For example, this error occurs if the common dialog box call specifies an invalid window handle.
CDERR_FINDRESFAILURE	The common dialog box function failed to find a specified resource.
CDERR_INITIALIZATION	The common dialog box function failed during initialization. This error often occurs when sufficient memory is not available.
CDERR_LOADRESFAILURE	The common dialog box function failed to load a specified resource.
CDERR_LOADSTRFAILURE	The common dialog box function failed to load a specified string.
CDERR_LOCKRESFAILURE	The common dialog box function failed to lock a specified resource.
CDERR_MEMALLOCFAILURE	The common dialog box function was unable to allocate memory for internal structures.
CDERR_MEMLOCKFAILURE	The common dialog box function was unable to lock the memory associated with a handle.
CDERR_NOHINSTANCE	The ENABLETEMPLATE flag was set in the Flags member of the initialization structure for the corresponding common dialog box, but you failed to provide a corresponding instance handle.
CDERR_NOHOOK	The ENABLEHOOK flag was set in the Flags member of the initialization structure for the corresponding common dialog box, but you failed to provide a pointer to a corresponding hook procedure.
CDERR_NOTEMPLATE	The ENABLETEMPLATE flag was set in the Flags member of the initialization structure for the corresponding common dialog box, but you failed to provide a corresponding template.
CDERR_REGISTERMSGFAIL	The RegisterWindowMessage function returned an error code when it was called by the common dialog box function.
CDERR_STRUCTSIZE	The lStructSize member of the initialization structure for the corresponding common dialog box is invalid.

The following error codes can be returned for the PrintDlg function:

Value	Meaning
PDERR_CREATEICFAILURE	The PrintDlg function failed when it attempted to create an information context.
PDERR_DEFAULTDIFFERENT	You called the PrintDlg function with the DN_DEFAULTPRN flag specified in the wDefault member of the DEVNAMES structure, but the printer described by the other structure members did not match the current default printer. (This error occurs when you store the DEVNAMES structure and the user changes the default printer by using the Control Panel.)
	To use the printer described by the DEVNAMES structure, clear the DN_DEFAULTPRN flag and call PrintDlg again. To use the default printer, replace the DEVNAMES structure (and the DEVMODE structure, if one exists) with NULL; and call PrintDlg again.
PDERR_DNDMMISMATCH	The data in the DEVMODE and DEVNAMES structures describes two different printers.
PDERR_GETDEVMODEFAIL	The printer driver failed to initialize a DEVMODE structure. (This error code applies only to printer drivers written for Windows versions 3.0 and later.)
PDERR_INITFAILURE	The PrintDlg function failed during initialization, and there is no more specific extended error code to describe the failure. This is the generic default error code for the function.
PDERR_LOADDRVFAILURE	The PrintDlg function failed to load the device driver for the specified printer.
PDERR_NODEFAULTPRN	A default printer does not exist.
PDERR_NODEVICES	No printer drivers were found.
PDERR_PARSEFAILURE	The PrintDlg function failed to parse the strings in the [devices] section of the WIN.INI file.
PDERR_PRINTERNOTFOUND	The [devices] section of the WIN.INI file did not contain an entry for the requested printer.
PDERR_RETDEFFAILURE	The PD_RETURNDEFAULT flag was specified in the Flags member of the PRINTDLG structure, but the hDevMode or hDevNames member was not NULL.
PDERR_SETUPFAILURE	The PrintDlg function failed to load the required resources.

The following error codes can be returned for the ChooseFont function:

Value	Meaning
CFERR_MAXLESSTHANMIN	The size specified in the nSizeMax member of the CHOOSEFONT structure is less than the size specified in the nSizeMin member.
CFERR_NOFONTS	No fonts exist.

The following error codes can be returned for the GetOpenFileName and GetSaveFileName functions:

Value	Meaning
FNERR_BUFFERTOOSMALL	The buffer pointed to by the lpstrFile member of the OPENFILENAME structure is too small for the filename specified by the user. The first two bytes of the lpstrFile buffer contain an integer value specifying the size, in bytes (ANSI version) or characters (Unicode version), required to receive the full name.
FNERR_INVALIDFILENAME	A filename is invalid.
FNERR_SUBCLASSFAILURE	An attempt to subclass a list box failed because sufficient memory was not available.

The following error code can be returned for the FindText and ReplaceText functions:

Value	Meaning
FRERR_BUFFERLENGTHZERO	A member of the FINDREPLACE structure points to an invalid buffer.
