Auugghh!! As the deadline approaches, he hurries to remove all the *wierd* bugs. I want to *activate* a string gadget upon entry to a dialog box. I am using Aztec 3.4b's ActivateGadget for Version 1.2 of Kickstart But it don't seem to work. I actually got it to display the cursor very quickly in the STRGADGET box, but then it disappears. Does anyone know what's going on? Does this work? (It must because I see it in other comercial products). HELP HELP--- I would appreciate any clues to where to go next. Thanks.

You wouldn't happen to be using HeliosMouse, would you? I witnessed the same phenomenon as a user, and later realized that what was happening was that after the string gadget activated itself, HeliosMouse was telling the system that I had clicked at the point where the mouse was. That point normally was not in the string gadget, so the "click" deselected the string gadget almost instantly after it came into existence.

However, since the original poster (quoted above) didn't say if he was using it, have a code fragment. Note: This is an *extremely* cheesy file requestor, and I don't recommend using it unless you're writing user-hostile programs. _-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_-_ Leo L.

From my Instant Application/Standard File program:
X if(!(STD_Window = OpenWindow(&STD_NewWindow))) {
X return 0;
X }
X
X /* This optional line will activate a string gadget */
X if ( IntuitionBase->lib_Version > 32 )
X {
X ActivateGadget(gadget,STD_Window,0L);
X }
This works fine. And will work under older versions of Intuition... just
won't have the gadget active. Shamelessly stolen from a sample program
on the Manx disk.
