I have a totally stable and high reliable Lazarus for windows mobile application. Some days ago I was inquired about this application by a firm who rents lots of windows CE handhelds. They offer me to test my application in a Windows CE handheld.

I tried. The application starts with no run time errors. The screen appears out of the handheld's screen. I saw only the left side of the screen. When I tried with a simple application that gets the files directories of the main application, it appears minimized and doesn't allow maximize. I must kill it with windows CE warm boot.

I'm using Lazarus 0.9.30 'cause the full screen routine is in trouble in the versions 1.0.X and later.

May someone here had an experience with this matter and can give me tips about what's wrong ?

Greetings from S?o paulo - Brazil

No experience with WinCE and Lazarus, but wasn't this problem fixed in Laz trunk?
I at least recall a lot of posts about this a while ago...

Someone suggested compile with Lazarus 1.1. I did it(downloaded and installed daily screenshot). The trouble with fullscreen still exists. I discovered when I ran in a windows mobile device emulator. I'll ask for a friend try test in a WinCE device again. At least I'll discover if the new version manage the screens right in Windows CE(although the fullscreen still in trouble)

Interesting topic

What is the difference between Windows CE, Windows 8 and Windows Mobile?

Which one can you use Lazarus to create "apps" for?

Windows 8 is used in tablets, notebooks and desktops. It has a great likeness to windows phone. Windows phone was create to substitutes operating systems that runs on handhelds and smartphones.

Windows Mobile and Windows CE was developed to run in handhelds and smartphones. There is a third operating system by MS named Pocket PC. Theoretically they are similar, but my experience shows me that Lazarus seems to run better under Windows Mobile 6 and later. I have a stable high reliable application for windows mobile hat have serious troubles to run under Windows CE and doesn't run in Pocket PC.

The Lazarus IDE is the same. You only must configure certain properties to generate executables to run in handhelds.

Hope I have give you some help

HI.
I use Lazarus & FPC to develop programs for WinCE since a few years (now on 1.0.8). Besides the usual beginner problems and errors, the whole system runs very well.
I've had a lot of problems with forms too until I understood that the window stack does not work very well.
I must mention that the handheld computers have a screen size fo 320 x 240 less the top and bottom bars.
After a lot of tests I took the decision to work with modal forms and control myself the display and hiding of the forms. The sequence wich works every time is the next one:
- all forms are created at the starting time
onto any form, need another form:
- prepare properties of the form to be dispayed
- Ret := OtherForm.ShowModal;
- do whatever to do whith ModalResult and OtherForm properties and data
- *Self.BringToFront;

*On another hand these are the forms properties changed from the default: *Form.Position := poScreenCenter;
Height := 320;
Width := 240;
*Form;KeyPreview := True;
All forms display without problem as full screen.
After a lot of time spent on checking different combinations, the former one gave predictable and acceptable results
Do not forget that with WinCE Microsoft didn't implement a lot of properties, methonds, etc. from a basic Windows OS.

Antonio.
