For all you bit/byte gurus ..
Say I wish to add 'dblclk' event to editlines… In the event designer there does not seem to be a 'list' of available events (no .. I don't have windows api manual handy .. but I did look in OI help).
SO ..
Could someone walk me through the steps of of using the Event Designer to add .. say dblclk to editlines ..
I really appreciate this ..

DSig,
You don't need to use the Event Designer to capture double clicks for editlines, unless you want to create a double click event for all editlines. If so (and I may be wrong here) I think the way it would have to be done is to create a promoted CREATE event that qualifies the WM_LBUTTONDBLCLK message for every window/control and then create a promoted WINMSG event that checks to see if the Window's Message was WM_LBUTTONDBLCLK. At that point you would add your logic. The problem here is that custom defined events don't exist at the form/control level so you can't have a separate dblclk event for each editline. You have only one dblclk event and all form/control specific code would exist there and would have to be referenced accordingly (Begin/End Case, If..then, etc.)
That being said, if you wanted to experiment on a simpler level then just add the following code to the CREATE event of your form:
Equ WM_LBUTTONDBLCLK to "0x203"
rv=Send_Message(@Window:".":Editline_name, "QUALIFY_EVENT", WM_LBUTTONDBLCLK, 1)
Then put code in the WINMSG event(s) for the editlines you are working with and…voila!
I am interested to know what you want to do, however, since double clicking on an editline already has the default behavour of selecting the text and I don't think this can be avoided.

Don,
Of course you are right about the d-click window processing .. though I wonder if it can be stopped? AND since it is forced why doesn't it appear in the events list?
What I am trying to find out is how the Event Designer works. It is a feature of OI that I want to become more familiar with.
Possibly a better example would be putting dblclk on a label. It has no default events (that I know of). This could be used as a 'options' launch point .. yes?
Now I could probably force this all through qualify event BUT how would it be done through the event designer .. Nothing worse than having a tool which should do all the bit work and having to turn around and having to do the bit work
