Remarks

Called from OpenRecordset to determine the default settings for columns based on their data types. The method associates the columns with a base style, determines the column title and width.

In the base class version of this method, cbLength is calculated with GetDisplaySize.

The method assigns the following base styles to the column depending on its data type:

• adVarChar: m_bsText
  
  
• adInteger,
  adBigInt,
  adSingle,
  adDouble: m_bsNumeric
  
  
• adBoolean: m_bsBoolean
  
  
• adCurrency: m_bsCurrency
  
  
• adDate: m_bsDate
  
  
• adLongVarBinary: m_bsBinary

·adGUID: m_bsGUID

The CGXAdoParam class holds the base style ids.

Set *pbColumnSettingsLocked to TRUE if you do not want the calling routine to further change your settings. If *pbColumnSettingsLocked is FALSE or pbColumnSettingsLocked is NULL, OnOpenRecordSet will modify the column widht and headers. Note: Be sure to check for pbColumnSettingsLocked = NULL in your overrides.
