	BOOL bInstall,
	LPCWSTR pszCmdLine
);

FoxPro declaration:

DECLARE INTEGER DllInstall IN shlwapi;
	INTEGER bInstall,;
	STRING  pszCmdLine

Parameters:

bInstall Value that is set to TRUE if the DLL is being installed, or FALSE if it is being uninstalled.

pszCmdLine String passed in by regsvr32 that indicates which setup procedure to use.

To use DllInstall with regsvr32, add a "/i" flag followed by a colon (:) and a string. The string will be passed to DllInstall as the pszCmdLine parameter. If you omit the colon and string, pszCmdLine will be set to NULL. The following example would be used to install a DLL:

regsvr32 /i:"Install_1" dllname.dll
