Created an application with Lazarus.
Program won't run on Tablet
1. Copied entire application folder over - still no go
2. Allowed app thru firewall - no go
3. turned off firewall - no go

App is mostly menu's and odbc.
App runs when moved to other windows 10 pc's
Tablet has i5 vPro cpu

Ideas?

Have you tried to run a 'hello world' program created using Lazarus on
the tablet?

It is hard to say what causes your program not able to run on the
tablet. But you can try adding items one-by-one and test running it on
the tablet. If a simple hello world can run on it then try adding some
buttons. Then try to add more items, TEdit, TMemo, a main menu and
finally the ODBC connection.

I have a simple gui form with buttons that is running on the tablet.

Will update as I go

it has to be a windows TABLET not android etc..

I have a tablet, Laz code runs fine on it.

In any case, if you are missing some support files then it could be a
problem or if the Bit size Is wrong also a problem..

if you put a 64 bit app on a 32 bit only Windows Tablet it may not
load/start etc.

Also, the tablet may not be hosting the underlayer for 32 bit apps if
the tablet is 64 bit.

Maybe Windows on a tablet are in S mode.

Do you get any error?

Appreciate all the support.

I went to:
Project Forms, selected my form.
The form showed up on my desktop, but was far right.

I dragged the form to the top left region on my development pc. At
this point the Left property of the form
displayed 118
Re-Built the app, put it on my tablet, and it's now showing.

Rookie mistake.
On my win32 stuff, when creating windows (CreateWindow), there's a
default window location CW_USEDEFAULT.
I figured the location on my screen wouldn't carry into the actual
location of the window when the app starts.

Any further comments appreciated. Nice environment

The form's position property might be relevant here.

https://lazarus-ccr.sourceforge.io/docs/lcl/forms/tposition.html

I'm not entirely confident that all of those work reliably over all
graphical environments, so I normally arrange that the form's design-
time position is fairly near the top-left and its size slightly
smaller than the smallest device I might need for remote-support
access.
