<br>
<b>function</b> ChangeDatabaseSettings(<b>var</b> Log: <b>String</b>; IgnoreErrors: Boolean; NewPassword: <b>String</b>; NewCryptoAlgorithm: TABSCryptoAlgorithm = DefaultCryptoAgorithm; NewPageSize: Integer = DefaultPageSize; NewPageCountInExtent: Integer = DefaultExtentPageCount; NewMaxConnections: Integer = DefaultMaxSessionCount): Boolean;
<br>

<br>
<b>Description</b>
<br>
Call ChangeDatabaseSettings to encrypt or decrypt database file, to change its crypto algorithm or to specify new page settings.
<br>

<br>
The Log parameter contains information about the errors occured.
<br>

<br>
Set IgnoreErrors to true if you want to ignore errors caused by corrupted data and to false otherwise.
<br>

<br>
The NewPassword parameter value different from default blank string indicates that the data is to be encrypted by this password. If NewPassword is blank then the file is decrypted.
<br>

<br>
NewCryptoAlgorithm specifies new algorithm used to encrypt database file.
<br>

<br>
Set NewPageSize if you want to optimize database file for extra small or large database size.
<br>
Allowed page size values are 100 - 65536 bytes. The default value is 4096. 
<br>

<br>
Set NewPageCountInExtent parameter if you want to optimize database file for extra small or large database size.
<br>
The default value is 8.
<br>

<br>
Set NewMaxConnections parameter if you want to increase or decrease allowed number of simultaneously connected users.
<br>
The default value is 500.
<br>

<br>
<b>Note:</b>
<br>
Changing settings could be a lengthy process if you are working with large database. Use BeforeChangeDatabaseSettings, OnChangeDatabaseSettingsProgress and AfterChangeDatabaseSettings event handlers to display the progress of changing database settings process.
