EDIT_INFO: Retrieves Status of Text Box Using Windows
Messages

EDIT_INFO shows how to access retrieval information from a
Microsoft(R) Visual Basic(TM) application. It uses
Microsoft Windows(TM) functions to retrieve information
about the status of a text box. The Visual Basic language
 does not provide this capability.

EDIT_INFO allows you to use the Windows message constants
 listed below for the following tasks:

>  EM_GETLINE: Copy a specific line of text from the edit
control.

>  EM_GETLINECOUNT: Retrieve the number of lines within
the edit control.

>  EM_GETSEL: Position the cursor at a specific character
location.

>  EM_LINEFROMCHAR: Retrieve the line number of a specific
character location.

>  EM_LINEINDEX: Retrieve the number of lines prior to a
specified character position.

>  EM_LINELENGTH: Retrieve the number of characters in a
specified line.

>  EM_REPLACESEL: Replace the specified text with another
text string.

For information on specifying the amount of text allowed
within a text control, search the Knowledge Base for
EM_LIMITTEXT.

For information on setting tab stops within a control,
 search the Knowledge Base for EM_SETTABSTOPS.

EDIT_INFO was built and tested under Microsoft Windows
version 3.1 and Visual Basic version 3.0.
