What is the difference between .Hide and .Show(false)

There is no difference, Hide() exists just for convenience.

That is what I was using. The other thing is all items where added from layout and not from any code. Why should that make any difference?

I would prefer to build it in Layout instead of in code, if possible.

Everything in layout is automatically Add()ed to the TopWindow. Well, IIRC, calling Add() on already added Ctrl is legal (it calls remove first), so theoretically you can put it in layout, but you still need to call the Add() in the code and probably also reposition it.

But if I do set it in code I need to set the size and position with .SetRect, is the x and y based upon the item it is added to?

Yes, everything is then positioned relatively to the top-left corner of the parent Ctrl.

Also I tried your code, but changing from App to T5, Code is:

...

And I get the following error:

t5: 1 file(s) built in (0:02.35), 2356 msecs / file, duration = 2356 msecs, parallelization 0%
Linking...
LIBCMTD.lib(crt0.obj) : error LNK2019: unresolved external symbol _main referenced in function ___tmainCRTStartup
C:\upp\out\MSC9.Debug.Debug_full\t5.exe : fatal error LNK1120: 1 unresolved externals

There were errors. (0:02.88)

You forget to add a GUI flag Wink

In addition I tried to do the add of the object in my code to my program, and just set position and FrameSet so I could see it. When I execute the code it does show up, but then when I start using it, it never comes back. The only way it shows up is if I do a PromptOK after I do the .Show.

I did the add in code using the following. It is for my own widget, that I have defined, after button.

W1.Add(E1.HCenterPos(10).VCenterPos(10));
W2.Add(E2.HCenterPos(10).VCenterPos(10));

E1.SetFrame(BlackFrame());
E2.SetFrame(BlackFrame());

I am using a image in the both cases, I just want the second image to show up for about 1 second then hide it again on top of the other image.

I think it is a bug on Windows Vista.

I don't see anything wrong with the posted line, the problem is probably somewhere else. Can't say where without seeing more of the code. Anyway, I am pretty sure that it is not related to Windows Smile
