Direct X and PNG Transparency on WM6.1 with .Net CF3.5

Hi all,
I'm trying to have transparent PNGs on my screen.
What is the best way to doing this ? I'm in C#, I tried DirectX, but it doesn't work.
What am I doing wrong ?
My code :
Code:
using System;
using System.Drawing;
using System.Windows.Forms;
using Microsoft.WindowsMobile.DirectX;
using Microsoft.WindowsMobile.DirectX.Direct3D;
using System.Runtime.InteropServices;
namespace Microsoft.Samples.MD3DM
{
// The main class for this sample
public class SimpleSMS : Form
{
// Our global variables for this project
Device device = null;
Texture texture = null;
Sprite sprite = null;
Rectangle rect;
public SimpleSMS()
{
// Set the caption
this.Text = "SimpleSMS";
this.MinimizeBox = false;
}
// Prepare the rendering device
public bool InitializeGraphics()
{
try
{
// Now let's setup our D3D parameters
PresentParameters presentParams = new PresentParameters();
presentParams.Windowed = true;
presentParams.SwapEffect = SwapEffect.Discard;
device = new Device(0, DeviceType.Default, this, CreateFlags.None, presentParams);
this.OnCreateDevice(device, null);
}
catch (DirectXException)
{
return false;
}
return true;
}
void OnCreateDevice(object sender, EventArgs e)
{
texture = TextureLoader.FromFile(device, @"badge.png");
sprite = new Sprite(device);
rect = new Rectangle(0, 0, 48, 48);
}
// All rendering for each frame occurs here
private void Render()
{
if (device != null)
{
device.Clear(ClearFlags.Target, System.Drawing.Color.Black, 1.0f, 0);
//Begin the scene
device.BeginScene();
device.RenderState.SourceBlend = Blend.SourceAlpha;
device.RenderState.DestinationBlend = Blend.InvSourceAlpha;
device.RenderState.AlphaBlendEnable = true;
sprite.Begin(SpriteFlags.AlphaBlend);
sprite.Draw(texture, rect, new Vector3(0.0f, 0.0f, 0.0f), new Vector3(100.0f, 100.0f, 0.0f), Color.White.ToArgb());
sprite.End();
//End the scene
device.EndScene();
device.Present();
}
}
// Called to repaint the window
protected override void OnPaint(System.Windows.Forms.PaintEventArgs e)
{
// Render on painting
this.Render();
// Render again
this.Invalidate();
}
// Called to repaint the window background
protected override void OnPaintBackground(
System.Windows.Forms.PaintEventArgs e)
{
// Do nothing to ensure that the rendering area is not overdrawn
}
// Close the window when Esc is pressed
protected override void OnKeyPress(
System.Windows.Forms.KeyPressEventArgs e)
{
// Esc was pressed
if ((int)(byte)e.KeyChar == (int)System.Windows.Forms.Keys.Escape)
this.Close();
}
/// <summary>
/// The main entry point for the application.
/// </summary>
static void Main()
{
SimpleSMS frm = new SimpleSMS();
// Initialize Direct3D
if (!frm.InitializeGraphics())
{
MessageBox.Show("Could not initialize Direct3D. " +
"This tutorial will exit.");
return;
}
Application.Run(frm);
}
}
}
Thanks for answers,
Scuse my bad english :-/

Not sure this helps, but RLTODAY works very well with transparent pngs in any WM version, and recently he released the source code:
http://rotlaus-software.de/forum/index.php?topic=1847.0

You can use ImagingFactory in OpenNETCF or other wrapper over the internet. PNGs with alpha work work for me.

AlphaControls
There is a project on Codeplex that can help you with transparency called AlphaControls. Also have a look on codeproject at the iPhone app clone

Click to expand...
Click to collapse
Thank you all for answers ...
I tried OpenNetCF, without any result.
Do you have a piece of code in example ?

Try this:

Android getting SMS body from inbox

Hi,
I want to get body of SMS when I click on one. I have tried an approach simmilar to contact picker. Here is my code :
public class Decrypt extends Fragment {
Button loadButton;
EditText smsDisplay;
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.decrypt, null);
// Button loadButton=(Button)v.findViewById(R.id.)
loadButton=(Button)v.findViewById(R.id.buttonLoad);
smsDisplay=(EditText)v.findViewById(R.id.editTextLoad);
loadButton.setOnClickListener(new OnClickListener() {
@override
public void onClick(View v) {
Intent sendIntent = new Intent(Intent.ACTION_VIEW);
sendIntent.setData(Uri.parse("sms:"));
//sendIntent.setType(Sm)
//sendIntent.putExtra("sms_body","");
startActivityForResult(sendIntent,2);
}
});
return v;
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
try{
// if (resultCode == Activity.RESULT_OK) {
Uri ur = data.getData();
Cursor c = getActivity().getContentResolver().query(ur, null, null, null, null);
if (c.moveToFirst()) {
String s = c.getString(c.getColumnIndex("body"));
System.out.println(s);
Toast.makeText(getActivity(), s, Toast.LENGTH_LONG).show();
smsDisplay.setText(s);
}
}catch(Exception e){
e.printStackTrace();
}
// }
}
}
It opens a Inbox like when I open original sms app in anroid, but when I click on one message it doesnt copy body of that sms in my edittext. Please couul you look at my code and find mistake?
Thanks a lot for your time

[Q]Service Socket closed by Background Foreground Lifecycle

I am writing an IRC Client, and so far as long as I dont send the app to the background and try to restore it it works fine. Tabs for multiple channels, the connected socket is in a bound service (started separately via INTENT and a startService call), etc and so on.
However, whenever I send the app to the background, then bring it back forward, the socket closes. I would have the same issue with screen rotation but I found the config setting that stops it from going through destroy/create on rotation. If I figure this out I may actually get rid of that since the issue will have been solved.
The other issue I seem to be having is that it takes a long time to re-bind to the service, and I have no idea why (the initial binding and startup is pretty quick, but re-binding to it seems to take forever, and when It does re-bind, the socket is closed).
Here are the code samples that I feel to be relevant, let me know if there's something more specific you want to see.
Code:
//This is the Service in question
public class ConnectionService extends Service{

Logcat...well...there isn't really any exception thrown, the code runs just fine...except that it closes the socket. I suppose that counts as an exception. Whenever I run the socket write command It throws a "Socket Closed" exception at me. No other crash involved.

Trying to make a session timer with a camera timer

Hello all ,
i'm trying to make a timer that will kick the user out after let's say a few seconds , i used asynctask for it
it supposed to work on all activities including one that uses a camera on a diffrent thread ( using vuforia api and needs internet )
for some reason when i do it the camera doesn't work
(the same thing happens when there is no internet connection - might be related)
any ideas why ?
here's my asynctask
Code:
private class LoadSessionASYNC extends AsyncTask<String, Void, String> {
long time;
long interval;
public LoadSessionASYNC(long seshTime, long interval) {
time = seshTime;
interval=inter;
}
@Override
protected String doInBackground(String... urls) {
while (time >0)
{
publishProgress();
try {
Thread.sleep(interval);
} catch (InterruptedException e) {e.printStackTrace();}
time= time-interval;
}
return null;
}
@Override
protected void onPostExecute(String result) {
Intent startfresh = new Intent(getBaseContext(),WelcomActivity.class);
startActivity(startfresh);
}
@Override
protected void onProgressUpdate(Void... values) {
Toast.makeText(getApplicationContext(), "time to finish : "+time/1000+"seconds", Toast.LENGTH_SHORT).show();
super.onProgressUpdate(values);
}
}

BLE Application (Display data from characteristic in a textView)

I used the BluetoothLeGatt example code to write an app that automatically connects to a bonded BLE peripheral upon launching the app. Now i am trying to display the data from one of the peripheral's characteristic in a textView. The BluetoothLeGatt example code only demonstrates this using ExpandableListView.OnChildClickListener, my app should require no user input and simply get he data from the characteristic. This is what i have so far:
Code:
private TextView mConnectionState;
private TextView mDataField;
private String mDeviceName;
private String mDeviceAddress;
private ExpandableListView mGattServicesList;
private BluetoothLeService mBluetoothLeService;
private boolean mConnected = false;
private BluetoothGattCharacteristic mNotifyCharacteristic;
private final String LIST_NAME = "NAME";
private final String LIST_UUID = "UUID";
// Code to manage Service lifecycle.
private final ServiceConnection mServiceConnection = new ServiceConnection() {
@Override
public void onServiceConnected(ComponentName componentName, IBinder service) {
mBluetoothLeService = ((BluetoothLeService.LocalBinder) service).getService();
if (!mBluetoothLeService.initialize()) {
Log.e(TAG, "Unable to initialize Bluetooth");
finish();
}
// Automatically connects to the device upon successful start-up initialization.
mBluetoothLeService.connect(mDeviceAddress);
}
@Override
public void onServiceDisconnected(ComponentName componentName) {
mBluetoothLeService = null;
}
};
// Handles various events fired by the Service.
// ACTION_GATT_CONNECTED: connected to a GATT server.
// ACTION_GATT_DISCONNECTED: disconnected from a GATT server.
// ACTION_GATT_SERVICES_DISCOVERED: discovered GATT services.
// ACTION_DATA_AVAILABLE: received data from the device. This can be a result of read
// or notification operations.
private final BroadcastReceiver mGattUpdateReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (BluetoothLeService.ACTION_GATT_CONNECTED.equals(action)) {
mConnected = true;
updateConnectionState(R.string.connected);
mConnectionState.setTextColor(Color.parseColor("#FF17AA00"));
invalidateOptionsMenu();
} else if (BluetoothLeService.ACTION_GATT_DISCONNECTED.equals(action)) {
mConnected = false;
updateConnectionState(R.string.disconnected);
invalidateOptionsMenu();
clearUI();
} else if (BluetoothLeService.ACTION_GATT_SERVICES_DISCOVERED.equals(action)) {
*edit*
UUID chara = UUID.fromString("c97433f0-be8f-4dc8-b6f0-5343e6100eb4");
List<BluetoothGattService> servs = mBluetoothLeService.getSupportedGattServices();
for (int i = 0; servs.size() > i; i++) {
List<BluetoothGattCharacteristic> charac = servs.get(i).getCharacteristics();
for (int j = 0; charac.size() > i; i++) {
BluetoothGattCharacteristic ch = charac.get(i);
if (ch.getUuid() == chara) {
mBluetoothLeService.readCharacteristic(ch);
mBluetoothLeService.setCharacteristicNotification(ch, true);
}
}
}
} else if (BluetoothLeService.ACTION_DATA_AVAILABLE.equals(action)) {
displayData(intent.getStringExtra(BluetoothLeService.EXTRA_DATA));
}
}
};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_device_control);
final Intent intent = getIntent();
mDeviceName = intent.getStringExtra(EXTRAS_DEVICE_NAME);
mDeviceAddress = intent.getStringExtra(EXTRAS_DEVICE_ADDRESS);
mConnectionState = (TextView) findViewById(R.id.connection_state);
mDataField = (TextView) findViewById(R.id.data);
Intent gattServiceIntent = new Intent(this, BluetoothLeService.class);
bindService(gattServiceIntent, mServiceConnection, BIND_AUTO_CREATE);
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
}
@Override
protected void onResume() {
super.onResume();
registerReceiver(mGattUpdateReceiver, makeGattUpdateIntentFilter());
if (mBluetoothLeService != null) {
final boolean result = mBluetoothLeService.connect(mDeviceAddress);
Log.d(TAG, "Connect request result=" + result);
}
}
@Override

}
});
}

mDataField.setText(data);
}
}

mDataField.setText(R.string.no_data);
}
private static IntentFilter makeGattUpdateIntentFilter() {
final IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction(BluetoothLeService.ACTION_GATT_CONNECTED);
intentFilter.addAction(BluetoothLeService.ACTION_GATT_DISCONNECTED);
intentFilter.addAction(BluetoothLeService.ACTION_GATT_SERVICES_DISCOVERED);
intentFilter.addAction(BluetoothLeService.ACTION_DATA_AVAILABLE);
return intentFilter;
}
I've successfully connected to an already bonded device, but now im trying to get the data from a characteristic using its uuid and display it in a textView. The BluetoothLeGatt example shows how a characteristic is selected by a user using an expandable list view onclick listener displaying the supported characteristics. I want to bypass all that and just get the data from the characteristic with the known uuid.
-EDIT-
figured it out
