Moto Q Flashlight allows the user to control the state of the camera flash. It has three modes of operation: Normal, Strobe, and Morse Code. The application consists of a Win32 DLL written in Visual C++ that exposes the native API to control the camera flash and a GUI written in Visual C#. Click here for more info.
There is an application out there for the Moto Q that allows you to enable / disable the camera flash and use it like a flashlight. I think it’s a great idea and could be a very useful application. Being cheap and a programmer I set out to code my own solution rather than fork over the $4.95 or make a keygen (seriously, why wrap the flash control functions in a C++ DLL but expose your key verification function in an unobfuscated IL binary ;). Ok you caught me I wrote a keygen and then moved on heh )
Thanks to the awesome support team at MOTODEV for pointing me towards the DeviceIoControl API:
The camera flash light can be controlled as a COM-port using “CAM1:” as a device.
Use the CreateFile() call to get a handle the camera driver, with the filename “CAM1:”.
Then use this file handle to make a call to DeviceIoControl() using the IOCTL (see the code below) and set the ‘Value’ value with a DWORD variable. 0=flash off and any other value=flash on.
The code shown below will change the state of the flash on a Moto Q. I’ve started work on a Win32 DLL to expose the native functions to a VB.NET or C# project. I’d like to start using C# more so I’ll probably write a frontend to control the flash.
CSPROPERTY_CAMERACONTROL_S InputBuffer;
CSPROPERTY_CAMERACONTROL_S OutputBuffer;
ULONG DataLength = sizeof(CSPROPERTY_CAMERACONTROL_S);
ULONG ReturnedLength; // Number of bytes returned in output buffer
hCam = CreateFile(TEXT("CAM1:"), GENERIC_WRITE | GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
InputBuffer.Property.Set = PROPSETID_VIDCAP_CAMERACONTROL;
InputBuffer.Property.Id = CSPROPERTY_CAMERACONTROL_FLASH;
InputBuffer.Property.Flags = CSPROPERTY_TYPE_SET;
InputBuffer.Flags = CSPROPERTY_CAMERACONTROL_FLAGS_MANUAL;
InputBuffer.Value = 1; //1==flash on, 0==flash off
if (!DeviceIoControl(hCam, IOCTL_CS_PROPERTY, &InputBuffer, DataLength, &OutputBuffer, DataLength, &ReturnedLength, NULL))
{
DWORD errCode = GetLastError();
}
WMReboot is a simple Visual Basic .NET 2.0 application to reboot your Windows Mobile 5 device. The application calls SetCleanRebootFlag and KernelIoControl API from coredll.dll to perform the reboot operation. All testing was done on my Moto Q. Click here for more info.
Just a quick update to release the CAB installer for WMStopWatch. I’ll go back and build a CAB for Moto Q Tweaker as well. Find the release here.
Grrr… I couldn’t stand the fact that such a simple application didn’t work well on different screen resolutions. This update should render better on most (all?) screen resolutions. Click here for more info.
So the other day I needed a stop watch and couldn’t find one. Figured I’d write a quick application for my Moto Q and WMStopWatch was born. WMStopWatch is a very simple stopwatch-like application for Windows Mobile devices written in VB.NET 2.0. Source code and release can be found here.
Just a small update to the Moto Q Tweaker program to remove some leftover debug code and improve the Tweak.IsEnabled() function. Find the updated release here.
The first application I’ve released for Windows Mobile is now on-line. Moto Q Tweaker is written in VB.NET 2005. The purpose of this application is to allow users to quickly enable/disable certain registry tweaks on the Motorola Q. Click here for more info.
Was running into some issues with the Nightfall theme. Pretty swamped right now so I figured I’d switch back to the default theme rather than fixing the broken one. Gallery and the random picture are not accessible from the main page until I figure out what to do with the broken theme.
On Tuesday I picked up a new Motorola Q from Sprint. So far I’m impressed with how easy it has been to use and the ammount of features it has. I’m a code junkie at heart and have been loving the fact that I can write VS.NET apps and debug them on the phone. Just found Broadcom has released their Bluetooth SDK so I’m working on a simple app to toggle the Bluetooth state without having to navigate several different menus.
