A recurring theme I see while debugging application compatibility issues has to do with the direct use of the window proc pointer. If the intended WNDPROC exists in a DLL that is located in Slot 0, the pointer “looks right” and is often mistakenly used...

Anyone witnessing Hopper in action can attest to the annoying chips, clicks and rings coming from the device under test – running many devices adds to the cacophony and your office is soon inhabitable. Hopper always seems to find the loudest speaker setting...

As many Hopper experts already know, running Hopper in Flight Mode (radio turned OFF) is an excellent way of isolating problems from the radio stack. In fact, my number one suggestion when I encounter a new problem is to try and repro in Flight Mode to...

In the first part we talked briefly about KITL timeouts. In this article we are going to give you a little bit more details and try to explain why it behaves the way it does. How did we run into this issue? It all started with Hopper (apparently...

l Debugging exceptions is the same process regardless of type, but often it is helpful to understand the difference between the most common types of exceptions: Raise Exception: This is most often sourced from a handled exception where the programmer...

Arguably, device hangs are the most challenging and elusive problems facing device developers today. One of the easiest ways of determining device hangs (or perf slowdowns) is to inspect the kernel’s RunList. It isn’t so much a list as it is a queue and...

There have been a few blogs that talk about the benefit of focusing hopper runs on individual applications to work out the stability bugs one application at a time. But, there comes a time when testing one by one may not be the best use of resources....

I was recently running hopper on a device that supported screen rotation and I realized that my test coverage was completely missing the rotation scenario. The device would switch between portrait and landscape mode if the user took a specific action...

Greetings all, please be patient while this blog is populated. I promise lots of good stuff is coming down the tube.

Recently I was challenged with a flash corruption problem and was forced to figure out how to boot a RAM image (ie: image NOT stored to flash) on my p2Sample device. I thought I would be clever and start with a tiny_kernel image and simply add the filesystem...

If you upgraded from an older version of Hopper to a more recent one, you probably noticed that the callstacks are gone from the Hopper logs. We made them optional for two reasons: 1. Printing out callstacks slowed down the run significantly ...

Over past several months I've noticed that when our partners come here onsite. They like to build Windows Mobile images on their laptops while trying to get other work done at the same time. The problem with that is when compiler, linker, etc. do their...

Why my private binaries do not show up in the image? I've been asked this question too many times by now. Many partners when testing their private changes have to figure it out the hard way. The reason why your updated binary doesn't show up in the...

Do you want to work on next generation Windows Mobile devices long before they become commercially available? Want to be the first one to work with and influence next year’s Windows Mobile devices? Then you’re in luck! The Windows Mobile team is looking...

Below is a well executed document from guestRx: Bulent Elmaci. Bulent has worked with Windows Mobile debugging for a long time and backs up his writing with a lot of experience. It is the first of a series of articles he has written to help our OEM's...

Posted by Javier Flores Assad (aka "The MTTF Dude") A new and enhanced version of "exception filtering" shipped with the Windows Mobile 6 kernel debugger. For full details follow this link: http://blogs.msdn.com/ce_base/archive/2007/04/25/windows...

There has been some confusion around the OS version supporting Windows Mobile 6. Sue Loh does an excellent job explaining the differences and even some of the “why” in the CE Base team blog . There is additional helpful information in the Comments section...

A very popular Hopper question I get is “How can I calculate actual expected device life from the 25 hour Hopper requirement?” Answer: you can’t – there is no way to calculate or ‘generalize’ how long your device/application will survive in real...

Hello everyone. My name is Mike Calligaro, and I’m a Development Lead in the JDP organization. We’re going to be doing a series of documents and tools for Windows Mobile OEMs here, and we’ll be placing them under the meta tag “FitNFinish.” FitNFinish...

This is the first of the FitNFinish articles that we’re planning to write. (If you’re wondering what FitNFinish is, read this .) As with all FitNFinish articles, the intended audience is Windows Mobile OEMs who write drivers and platform code. End users...

For anyone who hasn’t seen this content, MSDN is now hosting “eHow-tos” which are “multimedia documentation” modules covering a wide range of topics. Scrolling through the list you can find modules about application development, bringing up a new platform...

I have recently discovered that the CEPC platform is no longer shipped with Windows Mobile. Unfortunately, the Windows Mobile documentation contains many references to this platform (which you won’t have) and we are working hard on tightening up our documentation...

Hi, my name is Fernando Gonzalez. I have been working in the Windows CE team since January, 2002. I started in the CE Tools team (Platform Builder Debugger, remote tools), then moved to networking (Bluetooth, IR, Wifi) and finally in the JDP team. ...

I am not much of a programming book person, I am much more likely to select code and press "F1". However, I find myself reaching for a CE 6.0 book and have been finding it quite useful. "Windows Embedded CE 6.0 Fundamentals" [Pavlov, Belevsky][ISBN 0735626251...
