Routine Description:
This routine is called to write the name of the vendor's installer DLL,
the entry point of that DLL, and the name of the printer
The vendor setup information is stored as described below:
HKLM
\Software
\Microsoft
\Windows NT
\CurrentVersion
\Print
\VendorSetupInfo
\VendorInfoEnumerator N
\VendorSetup1 Vendor1Dll,EntryPoint "Printer1 Name"
\VendorSetup2 Vendor2Dll,EntryPoint "Printer2 Name"
.............................................................
\VendorSetupN VendorNDll,EntryPoint "PrinterN Name"
The value N of VendorInfoEnumerator is equal to the number of the printers
for which vendor setup is provided. That value will be used to enumerate
the Dll's provided by vendors in the process of calling the entry points
of those Dlls.
The type of VendorInfoEnumerator is REG_DWORD.
The value of each VendorSetupX key (where 1<= X <= N) is a string containing
the name of the VendorSetup DLL, the entry point of that DLL and the
corresponding printer name. WrireVendorSetupInfoInRegistry function
concatenates its input parameters to produce that value and to write in into
the registry. The type of every VendorSetupX value is REG_SZ.
The information about the function in migrate.dll which to be called after
the first administrator's logon is stored into the registry as it is shown
below:
HKLM
\Software
\Microsoft
\Windows
\CurrentVersion
\Run
\MigrationVendorSetupCaller
The value of MigrationVendorSetupCaller is:
rundll32.exe %WinRoot%\system32\spool\migrate.dll,CallVendorSetupDlls
The type of the value is REG_SZ.
Arguments:
pszVendorSetup - null terminated string containing both the name of the
vendor's DLL and the entry point of that DLL
pszPrinterName - null terminated string containing the name of the printer
Return Value:
ERROR_SUCCES in the case of success.
error code in the other case.
