Initializing the Lotus Driver
When you install the Lotus database driver, the Setup program writes a set of default values to the Microsoft® Windows® Registry in the Engines and ISAM Formats subkeys. You should not modify these settings directly; use the setup program for your application to add, remove, or change these settings. The following sections describe initialization and ISAM Format settings for the Lotus database driver.
Lotus Initialization Settings
The Jet\4.0\Engines\Lotus folder includes initialization settings for the msltus40.dll driver, used for external access to Lotus spreadsheets. Typical settings for the entries under this heading are shown in the following example.
win32=<path>\msltus40.dll
TypeGuessRows=8
ImportMixedTypes=Text
AppendBlankRows=4
FirstRowHasNames=Yes
The Microsoft Jet database engine uses the Lotus folder entries as follows.
| Entry | Description |
|---|---|
| win32 | The location of msltus40.dll. The full path is determined at the time of installation. |
| TypeGuessRows | The number of rows to be checked for the data type. The data type is determined based on the most frequently found data type in the selection. If there is a tie, the data type is determined in the following order: Number, Currency, Date, Text, Long Text. If data is encountered that does not match the data type guessed for the column, it is returned as a Null value. On import, if a column has mixed data types, the entire column will be converted according to the ImportMixedTypes setting.
The default number of rows to be checked is 8. |
| ImportMixedTypes | Can be set to MajorityType or Text. If set to MajorityType, columns of mixed data types will be cast to the predominate data type on import. If set to Text, columns of mixed data types will be cast to Text on import. The default is Text. |
| AppendBlankRows | The number of blank rows to be appended to the end of a WK1 worksheet before new data is added. For example, if AppendBlankRows is set to 4, Microsoft Jet will append 4 blank rows to the end of the worksheet before appending rows that contain data. Integer values for this setting can range from 0 to 16; the default is 01 (one additional row appended). |
| FirstRowHasNames | A binary value that indicates whether the first row of the table contains column names. A value of 01 indicates that, during import, column names are taken from the first row. A value of 00 indicates no column names in the first row; column names appear as F1, F2, F3, and so on. The default is 01. |
