Re: Set the cursor...

I've used the command a lot in Windows and it has always worked. The order of lockcursor and "set cursor" doesn't matter. I've tested on XP through Vista, though my stack was compiled with an earlier engine version. It isn't a system setting, the engine handles the cursor display. Are you sure you d...

Re: scrolling list / data grid question

What is the exact content of your scrolling field? I'm not sure what you mean by "reference tables"; are those just one-line strings? What you want to do is pretty common and not difficult, so something else is interfering. Assuming that the field contains just a 3-line text list, then arrow keys sh...

It's likely he also reads the user list. I suspect a question there with his name in it would attract his attention.

Re: Message Definitions

It sends the listed message to the object, just as the engine would. It isn't for writing scripts, it's for testing them.

You can use :

create <obj reference)> in group "groupName"

if you want a new object, or you can copy an existing one :

Re: scrolling list / data grid question

In the property inspector, set the listbehavior, locktext, and the dontwrap to true. That will make the field act like a selectable list. When the user clicks a line the field will get a selectionchanged message and also a mousedown, mouseup, etc. You can trap any of those and get the line number (t...

Re: enforce variable type checking?

It isn't that everything is converted to a string; it's that everything is a string. The engine then converts to whatever type it needs internally. It's pretty smart about that usually, but menuhistory must have been an oversight. The hilightedlines property does accept either empty or zero, and if ...

Re: Substituting Animated Buttons or Sprites for Default Buttons

I fought it for years, thought it was stupid and distracting. And we're by no means required to use that notation, you'll see lots of people who don't. But after a while I started to see the advantages and began using it myself. Now I'm hooked I'm afraid. There are plusses you don't at first anticip...

Re: Graphic effects displaying wrong color.

I saw that too but it was fixed in version 4.6.1. Is that what you're using? Also, I only saw it on Android so maybe you've found something else.

Re: Android - quitting application fails

That's good to know, I hadn't realized there was a difference in the hardware button behaviors. The latest release of LiveCode sends a "backKey" message when that key is pressed, so you can trap that if you need to. I haven't tested to see if issuing a "quit" command on "backKey" will crash, but sin...

Re: check to see if file is open before opening

The OP wants to know if a file is open that has not been opened in LC. The only way I know to do that is to try and open it. If it is already open by another app, and if the original app has locked it in use, the result will contain "can't open file". Some files are opened by apps without a lock; th...

Re: check to see if file is open before opening

You can do it by checking for errors: open file "notMyFile.txt" if the result is not empty then -- couldn't open it ... do whatever you need end if Or you can use the "try" structure: try open file "notMyFile.txt" catch tErr answer tErr -- or whatever end try I don't know of any native way to check ...

Re: messages path

This may sound sacrilegious, but maybe HyperCard was wrong. The notion of inserting or remove the script of one object (the card) from the message path of an object based on whether that object is a member of a different object (the background) seems an unnecessary ambiguity, and a particularly odd...
