Some animation at last!
Well, I finally got some animation working (: I used images from the Donuts sample and code from the DDEX3 sample to make it work. The tubular spaceship now rotates and also bounces around the screen edges. Looks cool! I ll write in detail tomorrow. Ciao!

Why would the controls not show up!
A colleague of mine had a strange problem today. He had written a small UI application for a Windows Mobile Professional device with many controls. The controls contained several check boxes, text boxes, labels and buttons. When he ran the dialog using the "Run Dialog" option in Visual Studio, it showed up correctly and when the program ran on the device a strange thing happened. Some of the controls would show up and others would not. It wasn't random, the same set of controls showed up every time ......

Cellular emulator and Device Emulator, COM port issues
Well, it looks like the magic that made the cellular emulator come up on COM3 in my previous post was not long lived. Once the cellular emulator came up, I started the device emulator and tried to set the "Serial Port 0" of the emulator to COM3, so that the device and the cellular emulator can talk to each other and that is where it went boom! Threw a message saying something like, "Unable to open COM3, cannot find the file specified". All my efforts to fiddle with disabling and enabling the bluetooth ......

Cellular emulator, COM3 in use please verify
I was trying to set up the cellular emulator with the windows mobile emulator on my laptop when the cellular emulator spat out "COM3 in use, please verify". I knew it was another classic case of some application holding a port and another application failing because of it. Such problems are usually solved by changing the order of installing those application. To find a solution I binged around (yes! I bing :) and found this msdn forum link. No surprise that many people had already gone through this. ......

Applications: Process Viewer update
I noticed that I hadn't added the filename associated with the process in the Process Info section last time. It struck me when looked at the PViewCE sample, which I mentioned about in this post. So I thought why not add the filename label, could anything else be simpler! I edited the dialog to include another static text control and added the code in AllignComponents() to beautify the control. But a small hiccup, when I ran the program just to test if it was displayed correctly, it wasn't to be ......
