//  Function:   MessageBoxFromStringIds 
// 
//  Synopsis:   Displays a simple message box taking its text from a string 
//              table instead of from user allocated strings. 
// 
//  Arguments:  [hwndOwner]      - window handle for the message box's owner 
//              [hinst]          - instance associated with the string table 
//              [idText]         - string id for the box's text string 
//              [idTitle]        - string id for the box's title string 
//              [fuStyle]        - style of message box 
//                                 (see Windows function MessageBox for styles) 
// 
//  Returns:    result from MessageBox 
// 
//  History:    6-24-94   stevebl   Created 
// 
//  Notes:      Each string is limited to MAX_STRING_LENGTH characters.

// 
//  Function:   MessageBoxFromStringIdsAndArgs 
// 
//  Synopsis:   Creates a message box from a pair of string IDs similar 
//              to MessageBoxFromStringIds.  The principle difference 
//              is that idFormat is an ID for a string which is a printf 
//              format string suitable for passing to wsprintf. 
//              The variable argument list is combined with the format 
//              string to create the text of the message box. 
// 
//  Arguments:  [hwndOwner] - window handle for the message box's owner 
//              [hinst]     - instance associated with the string table 
//              [idFormat]  - string id for the format of the box's text 
//              [idTitle]   - string id for the box's title string 
//              [fuStyle]   - style of the dialog box 
//              [...]       - argument list for text format string 
// 
//  Returns:    result from MessageBox 
// 
//  History:    6-24-94   stevebl   Created 
// 
//  Notes:      Neither the composed text string nor the title must be 
//              longer than MAX_STRING_LENGTH characters.
