Excel
Microsoft Excel is a spreadsheet developed by Microsoft for
Windows OS.
The default formats for
Excel are the
*.xls or
*.xlsx files.
Work with Excel database
- In the default setting of the
Windows register it is supposed that first row of any
Excel table contains column names. It is shown so that the possible first table row is not accessible (e.g. for the
PmaAdo and
PmaDatabase objects). To access this row it is necessary to set the following in the
Windows register:
in the key
HKEY_LOCAL_MACHINE\Software\Microsoft\Jet\4.0\Engines\Excel change the value
FirstRowHasNames from the value
01 (default) to
00.
- In the Excel table (sheet) the rows cannot be deleted.
- By means of the
PmaDatabase object it is not possible to read or write into cells in the
Excel table (sheet) if this cell is defined as calculated.
- If the
PmaDatabase object writes into the cells of the
Excel table (sheet) over which calculations are made or graphs are displayed, then it is suitable to set the "
Database type" configurator to
Excel 4.0 in the
PmaDatabase object by reason of the error in MS support of data type writing for other
Excel types.
- by the
PmaAdo object via the
ADO Provider Microsoft Excel Driver (*.xls, *.xlsx, *.xlsm, *.xlsb) or
Microsoft.Jet.OLEDB.4.0.
