class not registered

[skyyonk]

Hi all,

I have a hoverbutton.ocx file which i copied into windows\system folder in win98 OS. After compiling the application and running it, i got a class not registered error message. Is there anything missing? Please help. Thanks.

you have to register the ocx, copying it isn't good enough. run regsvr32 on it from the command prompt.

is registry necessary if specific ocx is compiled into the form and app? I am testing the app without presence of the OCX in the folder or registry and 'seems' to work fine??

Many 3rd party OCX's have licenses - both runtime and developement. Sometimes these need to be provided and/or registered.

OCX's are NEVER "compiled into" an application (.APP or .EXE)... the OS would then have no way to load them. They don't have to be in the current directory, though: The .OCX can be anywhere on your computer... the Registry enables windows to find the .OCX based on the CLSID (class id) that is stored in the form (.SCX) or class definition.

Registering an ocx is absolutely necessary.
