Are you talking about a COM Callable Wrapper (CCW) that allows non .NET CF applications be able to make use of COM objects exposed by your .NET assembly?

If you are the answer is you can't do this. The .NET Compact Framework does not currently support the hosting APIs etc required to host the .NET CF runtime within another (native) process.

Hope this helps,

Screen Orientation

Hello,

I want to handle the event when the screen orientation changes. I searched the web but nothing.

I want to put my code for each orientation based on the orientation. Is there any event that I can/should handle? I was thinking of capturing the orientation hardware's button pressed event but could not find it.

Thanks for your help,

CodingYoshi

What language are you developing in?

When the orientation changes the size of your fullscreen window will automatically change. So one way to detect changes is to handle the window size changed event or window message that occurs in your chosen framework.

If you need to tell if you are in portrait or landscape mode you can determine this by then checking if the current window width is greater than the height.

If for some reason you actually need to determine the true orientation of the device (i.e. 0, 90, 180, 270 degrees) you can do this but the answer is a little different depending upon your programming language/environment of choice.

Hope this helps,
Christopher Fairbairn

Hi Christopher,

Thanks for the reply. I am using .NET (VB, C#, C++). Your suggestions definitely help and I will try them and let you know if I run into trouble.

Thanks,

Within your .NET Compact Framework application you can handle the OnSize event for your form, when the device changes orientations it will cause the form to be resized and by comparing the the width to height ratio you can determine if the device is in portrait or landscape mode.

On a Windows Mobile 5.0 or higher device you may also like to investigate the SystemState.DisplayRotation property (http://msdn2.microsoft.com/en-us/library/microsoft.windowsmobile.status.systemstate.displayrotation.aspx[^])

Hi Christopher,

The only event I found that has anything to do with the size is Resize. However, this event is not raised when orientation changes. None of the other events look useful to me.

Any other ideas?

Thanks,

CodingYoshi

Hmm what operating system/mobile device type are you targeting?

Hi Guy

I Had doen this in my project. we want to create a custom event eith Platform Invoke.

i means like this

u create this P/Invoke mthoed
[DllImport("coredll.dll", SetLastError=true)]
private static extern int ChangeDisplaySettingsEx(
string lpszDeviceName,
byte[] lpDevMode,
IntPtr hwnd,
CDS dwflags,
IntPtr lParam);

after create a DEMODE class like this
internal class DEVMODE
{
public const short Size = 192;
private byte[] mData;

public DEVMODE()
{
mData = new byte[Size];
BitConverter.GetBytes((short)Size).CopyTo(mData, 68);
}

public byte[] ToByteArray()
{
return mData;
}

public DM Fields
{
get
{
return (DM)BitConverter.ToInt32(mData, 72);
}
set
{
BitConverter.GetBytes((int)value).CopyTo(mData, 72);
}
}
public int DisplayOrientation
{
get
{
return BitConverter.ToInt32(mData, 188);
}
set
{
BitConverter.GetBytes(value).CopyTo(mData, 188);
}
}
}

[Flags()]
internal enum DM
{
ORIENTATION = 0x00000001,
PAPERSIZE = 0x00000002,
PRINTQUALITY = 0x00000400,
COLOR = 0x00000800,
BITSPERPEL = 0x00040000,
PELSWIDTH = 0x00080000,
PELSHEIGHT = 0x00100000,
DISPLAYORIENTATION = 0x00800000,
DISPLAYQUERYORIENTATION = 0x01000000,
}

then let's crate a method , within that create object above class and call Above P/Invoke methods and pass arugs. If P/Invoke method return >0 when get success result from the OS, after get >0 u must inove ur event next line. and od ur work.

i hope this is help to you.

Thanks

I created a mobile web page with an ObjectList control. The control works fine on my Treo (running windows mobile 5.0), however, the links do not work on my AT&T tilt (running windows mobile 6.0). Do I need to somehow enable javascript on my tilt or does it possibly require a configuration change for the webserver to recognize my browser? Any ideas? Thank you.

I am working on a project where I need to communicate with a virtual comport via bluetooth on a pocket pc 2003. I know Microsoft has a Bluetooth api, but it is only for c++. From the looks of the c++ code there are very few steps to getting a bluetooth serial port set up. Can anyone give me guidance on api/dll to use or vb code examples for the bluetooth api?? Any general help on starting a bluetooth app for a pocket pc with visual basic would also be appreciated. Thanks in advance for the help.

Hi paulraj,

Can you share the code you use to call ShellExecuteEx?

Windows CE (and hence Windows Mobile) have no concept of a current working directory. So for APIs such as ShellExecuteEx you need to specify the full path to the file you want to display. An exception to this rule is that some APIs will automatically look in the \windows folder if a path is not specified.

Are you by chance asking ShellExecuteEx to open "paul" instead of "\temp\paul"?

Hope this helps,
