SUMMARY

This article demonstrates how to use OLE automation to create a mail merge in Microsoft Office Word 2003 using data from a Visual FoxPro (VFP) for Windows table.

MORE INFORMATION

Below is the Visual FoxPro for Windows code using the Word.Application object model that performs the mail merge using an ODBC data source to an existing Visual FoxPro table. This code can use an existing data source name (DSN), created in the ODBC Driver Manager, or it can create one on the fly utilizing an API call to add and use the DSN. In the example below, "Visual FoxPro Tables" is the DSN created in the ODBC Driver Manager and points to the \Samples\Data folder in the VFP home folder. These paths will most likely have to be changed to reflect the users' paths.

Note This code was tested with the Service release-1 (SR-1) for Word 97 and Microsoft Office Word 2003. Using prior versions of Word 97 causes a Type Mismatch and other OLE errors.

Create a program and enter the following code:
  ***/ Begin program code /***
   * Code to create a new data source to a VFP table.
   *
   * Use the Declare DLL function to prototype the
   * SQLConfigDataSource function.
   * Using SQLConfigDataSource prevents having to go into
   * the ODBC Driver Manager and create the DSN.

   ***
   

IF VAL(SUBSTR(VERSION(4),2,1))>7
lthemes=_screen.Themes
_screen.Themes=.f.
ENDIF

   DECLARE Integer SQLConfigDataSource in odbccp32.dll Integer, ;
      Integer, String, String

   ***
   * Create a string containing the settings appropriate to the driver.
   * The following is an example for the Microsoft VFP ODBC driver
   * accessing the Customer.dbf file.
   ***

   *** Change the path below to point to the Customer table ***
   *** in the \Samples\Data folder.                      ***
   settings="DSN=visual foxpro tables"+chr(0)+;
             "Description=VFP ODBC Driver"+chr(0)+;
             "SourceDB=e:\vfp7\samples\data"+chr(0)+;
             "SourceType=DBF"
   =SQLConfigDataSource(0,1,"Microsoft Visual FoxPro Driver",settings)

   * NOTE: Ensure there are no spaces on either side of the equal sign (=).

   ON ERROR DO errhand WITH ERROR(), MESSAGE(),  MESSAGE(1), PROGRAM( ),
   LINENO( ) && Trap OLE & other errors.

   * Initialize variables passed to Word to create form letter.
