## Detailed Description

A class providing functions to install or remove ODBC driver.

## Member Function Documentation

const char* CPLODBCDriverInstaller::GetLastError | ( |  | ) | const
| inline

If InstallDriver returns FALSE, then GetLastError then error message can be obtained by calling this function.

Internally, it calls ODBC's SQLInstallerError function.

DWORD CPLODBCDriverInstaller::GetLastErrorCode | ( |  | ) | const
| inline

If InstallDriver returns FALSE, then GetLastErrorCode then error code can be obtained by calling this function.

Internally, it calls ODBC's SQLInstallerError function. See ODBC API Reference for possible error flags.

const char* CPLODBCDriverInstaller::GetPathOut | ( |  | ) | const
| inline

Path of the target directory where the driver should be installed.

For details, see ODBC API Reference and lpszPathOut parameter of SQLInstallDriverEx

int CPLODBCDriverInstaller::InstallDriver | ( | const char * | pszDriver,
|  | const char * | pszPathIn,
|  | WORD | fRequest = `ODBC_INSTALL_COMPLETE`
| ) |  |

Installs ODBC driver or updates definition of already installed driver.

Interanally, it calls ODBC's SQLInstallDriverEx function.

Parameters

  pszDriver | - The driver definition as a list of keyword-value pairs describing the driver (See ODBC API Reference).
  pszPathIn | - Full path of the target directory of the installation, or a null pointer (for unixODBC, NULL is passed).
  fRequest | - The fRequest argument must contain one of the following values: ODBC_INSTALL_COMPLETE - (default) complete the installation request ODBC_INSTALL_INQUIRY - inquire about where a driver can be installed

Returns
  TRUE indicates success, FALSE if it fails.

int CPLODBCDriverInstaller::RemoveDriver | ( | const char * | pszDriverName,
|  | int | fRemoveDSN = `FALSE`
| ) |  |

Removes or changes information about the driver from the Odbcinst.ini entry in the system information.

Parameters

  pszDriverName | - The name of the driver as registered in the Odbcinst.ini key of the system information.
  fRemoveDSN | - TRUE: Remove DSNs associated with the driver specified in lpszDriver. FALSE: Do not remove DSNs associated with the driver specified in lpszDriver.

Returns
  The function returns TRUE if it is successful, FALSE if it fails. If no entry exists in the system information when this function is called, the function returns FALSE. In order to obtain usage count value, call GetUsageCount().
