Developing for PDA - C# / C Sharp

David

Hi there,

I have to re-write our website to be able to be viewed on PDAs. However, I
am not finding much information about writing for PDA apart from palmpilot.

I have a Xda Exec (Mobile phone device on the O2 network in the UK). This is
currently running Windows Mobile. The UA is...

Mozilla/4.0+(compatible ;+MSIE+4.01;+Wi ndows+CE;+PPC;+ 240x320)

The UA string suggests that the screen is 240x320, though I am not quite
sure, as my weblogs suggest 640x480, but it doesn't seem like this either.

I am finding NOT A LOT of info about writing pages to suit.

For example, I need to write for PDA devices in general...

How do I detect the device? Do I rely on the UA string? What would change in
the UA string? (Naturally, I want a consistent method).

What would be the target screen resolution?

Are there any "watch out for..." to do with programming for this?

I have viewed our website on the device and notice quite a few things.
1. Not all CSS styles work. Most of it does, but some, for example, hiding
certain parts of the page using the visibility option of css doesn't work.
2. Javascript appears not to work. However, what is weird, DIV tags set to
hide (as in pop-down menu's) are hidden (in contrast to 1. above)
3. On this device, I can set various view modes. One column, Default,
Desktop. The screen looks VERY different between them all. Is there a way to
detect which mode is viewing?

Any pointers would be very much appreciated.

Best regards,
Dave Colliver.

Best book on developing server controls?

by: Todd | last post by:

Hello, I'm looking for a book with in-depth coverage of developing server controls, particularly custom controls. Ideally, the book would have a good amount of how-to's and best practices, but also serve as a fairly complete reference. It doesn't need a whole lot in the way of introductory material as I already have most of the basics down. So I've narrowed my search down to 2 books: "Developing Microsoft ASP.NET Server Controls and...

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
