RichEdit20A control doesn't attend OnChange Callbacks
  Hi community,

It seems that RichEdit control doesn't attend OnChange events. I wrote this code (excerpt):

nsDialogs::CreateControl /NOUNLOAD "RichEdit20A"  ${WS_VISIBLE}|${WS_CHILD}|${WS_CLIPSIBLINGS}|${WS_TABSTOP}|${WS_VSCROLL}|${ES_MULTILINE}|${ES_WANTRETURN} ${WS_EX_STATICEDGE} 60 120 300 60 ''"

Pop $InstallKeyMultiline 


GetFunctionAddress $0 InstallKeyRTF_OnChange 

nsDialogs::OnChange $InstallKeyMultiline $0 

>

I've changed by macros (${NSD_OnChange} $InstallKeyMultiline "InstallKeyRTF_OnChange")
but it didn't work at all.

Any ideas,

Thank you in advance,
Gabriel

Try the more generic OnNotify (WM_NOTIFY). It really depends on what message(s) you want to handle?

I'm afraid it didn't work, or I don't know how to put in paramaeters OnNotify.

Determine which window message you need to handle (on MSDN) and find out how you need to receive it. For example, some Windows controls send a WM_NOTIFY message which is what fires the OnNotify function. OnChange is just a handler for a couple of common window messages but not all. If none of the nsDialogs callbacks work chances are nsDialogs does not handle that particular window message.
