The MsiViewGetError function returns the error that occurred in the MsiViewModify function.

Syntax

C++MSIDBERROR MsiViewGetError(
  __in     MSIHANDLE hView,
  __out    LPTSTR szColumnNameBuffer,
  __inout  DWORD *pcchBuf
);

Parameters

hView [in]

Handle to the view.

szColumnNameBuffer [out]

Pointer to the buffer that receives the null-terminated column name. Do not attempt to determine the size of the buffer by passing in a null (value=0) for szColumnName. You can get the size of the buffer by passing in an empty string (for example ""). The function then returns MSIDBERROR_MOREDATA and pcchBuf contains the required buffer size in TCHARs, not including the terminating null character. On return of MSIDBERROR_NOERROR, pcchBuf contains the number of TCHARs written to the buffer, not including the terminating null character. This parameter is an empty string if there are no errors.

pcchBuf [in, out]

Pointer to the variable that specifies the size, in TCHARs, of the buffer pointed to by the variable szColumnNameBuffer. When the function returns MSIDBERROR_NOERROR, this variable contains the size of the data copied to szColumnNameBuffer, not including the terminating null character. If szColumnNameBuffer is not large enough, the function returns MSIDBERROR_MOREDATA and stores the required size, not including the terminating null character, in the variable pointed to by pcchBuf.

Return Value

This function returns one of the following values.

Error code	Meaning
MSIDBERROR_INVALIDARG	An argument was invalid.
MSIDBERROR_MOREDATA	The buffer was too small to receive data.
MSIDBERROR_FUNCTIONERROR	The function failed.
MSIDBERROR_NOERROR	The function completed successfully with no errors.
MSIDBERROR_DUPLICATEKEY	The new record duplicates primary keys of the existing record in a table.
MSIDBERROR_REQUIRED	There are no null values allowed; or the column is about to be deleted, but is referenced by another row.
MSIDBERROR_BADLINK	The corresponding record in a foreign table was not found.
MSIDBERROR_OVERFLOW	The data is greater than the maximum value allowed.
MSIDBERROR_UNDERFLOW	The data is less than the minimum value allowed.
MSIDBERROR_NOTINSET	The data is not a member of the values permitted in the set.
MSIDBERROR_BADVERSION	An invalid version string was supplied.
MSIDBERROR_BADCASE	The case was invalid. The case must be all uppercase or all lowercase.
MSIDBERROR_BADGUID	An invalid GUID was supplied.
MSIDBERROR_BADWILDCARD	An invalid wildcard file name was supplied, or the use of wildcards was invalid.
MSIDBERROR_BADIDENTIFIER	An invalid identifier was supplied.
MSIDBERROR_BADLANGUAGE	Invalid language IDs were supplied.
MSIDBERROR_BADFILENAME	An invalid file name was supplied.
MSIDBERROR_BADPATH	An invalid path was supplied.
MSIDBERROR_BADCONDITION	An invalid conditional statement was supplied.
MSIDBERROR_BADFORMATTED	An invalid format string was supplied.
MSIDBERROR_BADTEMPLATE	An invalid template string was supplied.
MSIDBERROR_BADDEFAULTDIR	An invalid string was supplied in the DefaultDir column of the Directory table.
MSIDBERROR_BADREGPATH	An invalid registry path string was supplied.
MSIDBERROR_BADCUSTOMSOURCE	An invalid string was supplied in the CustomSource column of the CustomAction table.
MSIDBERROR_BADPROPERTY	An invalid property string was supplied.
MSIDBERROR_MISSINGDATA	The _Validation table is missing a reference to a column.
MSIDBERROR_BADCATEGORY	The category column of the _Validation table for the column is invalid.
MSIDBERROR_BADCABINET	An invalid cabinet name was supplied.
MSIDBERROR_BADKEYTABLE	The table in the Keytable column of the _Validation table was not found or loaded.
MSIDBERROR_BADMAXMINVALUES	The value in the MaxValue column of the _Validation table is less than the value in the MinValue column.
MSIDBERROR_BADSHORTCUT	An invalid shortcut target name was supplied.
MSIDBERROR_STRINGOVERFLOW	The string is too long for the length specified by the column definition.
MSIDBERROR_BADLOCALIZEATTRIB	An invalid localization attribute was supplied. (Primary keys cannot be localized.)

 

Note that in low memory situations, this function can raise a STATUS_NO_MEMORY exception.

Remarks

You should only call the MsiViewGetError function when MsiViewModify returns ERROR_INVALID_DATA, indicating that the data is invalid. Errors are only recorded for MSIMODIFY_VALIDATE, MSIMODIFY_VALIDATE_NEW, and MSIMODIFY_VALIDATEFIELD.

If ERROR_MORE_DATA is returned, the parameter that is a pointer gives the size of the buffer required to hold the string. Upon success, it gives the number of characters written to the string buffer. Therefore you can get the required size of the buffer by passing a small buffer (one character minimum) and examining the value at pcchPathBuf when the function returns MSIDBERROR_MOREDATA. Do not attempt to determine the size of the buffer by passing in null as szColumnNameBuffer or a buffer size of 0 in the DWORD referenced by pcchBuf.

Once MSIDBERROR_NOERROR is returned, no more validation errors remain. The MSIDBERROR return value indicates the type of validation error that occurred for the value located in the column identified by the szColumnNameBuffer.
