Routine Description:

|
DllMain cannot be counted on for anything. Do not put any code here!!

Arguments:
|

|
|
hInstance - Specifies the instance handle of the DLL (and not the parent EXE or DLL)

dwReason - Specifies DLL_PROCESS_ATTACH or DLL_PROCESS_DETACH. We specifically
|

disable DLL_THREAD_ATTACH and DLL_THREAD_DETACH.

|
lpReserved - Unused.

Return Value:

DLL_PROCESS_ATTACH:

TRUE if initialization completed successfully, or FALSE if an error

|

DLL_PROCESS_DETACH:

Always TRUE.

other:

unexpected, but always returns TRUE.

Routine Description:
|
|
|
|
Winnt32PluginInit is called when WINNT32 first loads w95upg.dll, before
|
|
any wizard pages are displayed. The structure supplies pointers to
|
|
WINNT32's variables that will be filled with valid values as WINNT32
|
|
runs.
|
|
|
|
Control is passed to the code in init9x.lib.
|
|
|
|
Arguments:
|
|
|
|
Info - Specifies the WINNT32 variables the upgrade module needs access
|
|
to. Note that this is actually a PWINNT32_WIN9XUPG_INIT_INFORMATION_BLOCK
|
|
(which itself holds the normal initialization block..)

Return Value:

Routine Description:

Winnt32PluginGetPages is called right after Winnt32PluginInit. We return

three arrays of wizard pages, and WINNT32 inserts them into its master
|
|
wizard page array. Because no wizard pages have been displayed, the user

has not yet chosen the upgrade or fresh install option. Therefore, all

our wizard pages get called in all cases, so we must remember NOT to do
|

any processong in fresh install.

|
Arguments:
|
|
|
|
FirstCountPtr - Receives the number of pages in FirstArray and can be zero.
|
|
|
|
FirstArray - Receives a pointer to an array of FirstCountPtr property
|
|
sheet page structs.
|
|
|
|
SecondCountPtr - Receives the number of pages in SecondArray and can be zero.
|
|
|
|
SecondArray - Receives a pointer to an array of SecondCountPtr property
|
|
sheet page structs.
|
|
|
|
ThirdCountPtr - Receives the number of pages in ThirdArray and can be zero.
|
|
|
|
ThirdArray - Receives a pointer to an array of ThirdCountPtr property

sheet page structs.

See WINNT32 for more information on where these wizard pages are inserted

into the master wizard page list.
