hi,

i can call dll in using javascript in IE. My page failed in Mozilla. Could u tell me how can i call that dll in Mozilla. I want to support dual browser (IE and Mpzilla). Pls help me.

Basically you can't. At the end of the day if you want to do something via a DLL that could compromise the user's security they will have to install an add in of some kind, ActiveX with IE or a Gecko extension.

BHO function from javascript.

You call it the same as any COM class. Use new ActiveXObject and the prog id to create an instance and then call the methods. Unless the browser security settings are extremely low it is unlikely that you'll be able to create the object to begin with though. If you need more help then provide details of waht you have tried, the BHO's prog id and some details of what it does.

You need to use RegAsm, see http://msdn.microsoft.com/en-us/library/tzat5yw6(VS.80).aspx. Once you do that you can use the .NET assembly like another COM library. Many .NET classes are already COM enabled when the framework installs, e.g. System.Random. You can find these in the HKCR hive of the registry. Like any ActiveX control there maybe security issues trying to use in a browser though.
