SetFileSize Method

Sets the size of a file or alternate stream.


int SetFileSize(const QString& qsFileName, qint64 lSize, const QString& qsPassword);


This method sets the size of the file or alternate stream specified by FileName.

The value passed for FileName must be a vault-local absolute path.

The Size parameter specifies the new size of the file or alternate stream, which must be greater than or equal to 0.

Applications can also change the size of a file or alternate stream using the stream objects returned by the OpenFile and OpenFileEx methods.

Note: This method can only be called when Active is true, and cannot be called within events.

Error Handling

This method returns a result code; 0 indicates success, while a non-zero error code indicates that this method encountered an error during its execution. If an error occurs, the GetLastError() method can be called to retrieve the associated error message. (Note: This method's result code can also be obtained by calling the GetLastErrorCode() method after it returns.)
