Hello,

I'd written two activex-dlls.
In these activeX-dlls are some forms.
How can I react on a button-click-event on a form of the activex-dll-1 in activex-dll-2?

Any suggestions?

If your app knows the hwnd of the other dll you can use sendmessage to let the other know when something happens. The way I have done this (only ever done it with IE toolbars and sidebars) is to do a search for windows with a cetain name using enumwindows, when I get the window name I want I use sendmessage to send the message and enumwindowproc to catch it at the other end.

Its all win32 api stuff, there is a win32 api forum. A great reference tool is available from that tells you what all the calls do.
