If you haven't done so already, install the Microsoft Excel ODBC driver
that ships with Visual FoxPro. To connect to a Microsoft Excel data source,
you must install the Microsoft Excel ODBC Driver and set up a Microsoft
Excel data source through the ODBC Microsoft Excel Setup dialog box in the
Windows Control Panel. This is a level 1 ODBC driver, so the data source is
a directory name or the current directory, as indicated in the Setup dialog
box. The currently shipping Microsoft Excel ODBC driver provides an option
in the Setup dialog box to specify Microsoft Excel versions 3.0 - 4.0 or
Microsoft Excel version 5.0 files.
The following is a code sample that "connects" to a Microsoft Excel data
source. In a Visual FoxPro application, you will most likely place this in
a separate program file or in the Load or Init events of a form (.scx
file).
*-- Connect to an Microsoft Excel Data Source
* The parameter passed with SQLCONNECT is the name of the data source.
* The default for Microsoft Excel is Excel Files. If there is any
* trouble with this, execute it with no parameter and a list of
* currently available data sources will come up. The text of the
* listing that pertains to Microsoft Excel is the actual value to pass
* as a parameter. Retry it with that value.
*
* Still from within the SQLCONNECT() function, a "Select Workbook"
* dialog will come up. Next, the program performs some error checking.
* Finally, Microsoft Excel is told which sheet of the workbook is desired
* within the SQLEXEC() function with the "Sheetn$" where "n" is a
* number from 1 to the number of sheets in the workbook.
nConnHand = SQLCONNECT("Excel Files")
IF nConnHand > 0
=MESSAGEBOX("Connected to Microsoft Excel File",0)
ELSE
=MESSAGEBOX("Unable to connect to Microsoft Excel File ..",0)
ENDIF
nXResult = SQLEXEC(nConnHand, 'SELECT * FROM "Sheet1$"','MyCursor')
