[Q]: DLL load

Hi all,

What are the changes that needs to be done to
load the DLL during runtime [in registry], i.e., when
an application using this DLL is run ?
presently my DLL is getting loaded at boot up time.
I would like to postpone this DLL load at runtime.

It is getting loaded at boot time, so it is a driver?

What registry entry did you put in, remove it. It might be in
HKLM\Drivers\Builtin

Yes, you are right.
It is a driver and its registry is in Builtin.
Just removing this registry would suffice ?

hi,
yes, that is true...
move it to HKLM\Drivers\Builtin
give the following details..
"SysIntr"=
"Dll"=".dll"
"Prefix"="XXX"
"Order"=
I assume that it is a stream interface driver

Hello Bruce,

I tried removing the Builtin registry and now it has not loaded my driver at
boot up time.
but when i run my application that needs my driver, it is not getting loaded
dynamically..?
Is there any registry setting for dynamic loading of DLLs ?

regards
sajid

Are you loading it as a driver? Then you need those registry settings, but
put them in a different key.

I thought that you were using LoadLibrary, but even then your driver might
be looking for a certain registry key.

Yes,
I did change the registry entry from:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\audio]
"Prefix"="WAV"
"Dll"="audio.dll"
"Order"=dword:0

to:
[HKEY_LOCAL_MACHINE\Drivers\audio]
"Prefix"="WAV"
"Dll"="audio.dll"
"Order"=dword:0

thats is, I have removed my driver from \Builtin.

Even then I have observed that when I run my applications
my driver is not getting loaded.

how can my driver can be detected at
runtime by its upper layer ?

regards
sajid

You will need to manually load it, there is nothing that will do it for you
once you disable the boot time loading.

ActivateDeviceEx() is what you need.

What do you mean by "its upper layer"?

upper layer means the driver/code that is using my driver entry points.
