How can I unregister to the GSM Network?

Does someone know this? I want to unregister from the GSM network, but not enter the flightmode (I still need SIM access, and it should be fast). The following code works fine on a S100 (WM2003), but the 9100 (WM5) refuses to unregister. Registering works fine on both devices.
Code:
GsmControl::GsmControl()
{
errorMsg = TEXT("No ERROR/SUCCESS message to display.");
hLineApp = NULL;
hLine = NULL;
LineInitializeExParams.dwTotalSize = sizeof(LineInitializeExParams);
LineInitializeExParams.dwNeededSize = 0;
LineInitializeExParams.dwUsedSize = 0;
LineInitializeExParams.dwOptions = LINEINITIALIZEEXOPTION_USEEVENT;
LineInitializeExParams.Handles.hEvent = NULL;
LineInitializeExParams.dwCompletionKey = 0;
dwLineAPIVersion = TAPI_CURRENT_VERSION;
GsmInitialize();
}
HRESULT GsmControl::GsmInitialize()
// Initializes TAPI interface
{
res = lineInitializeEx(&hLineApp, NULL, NULL, NULL, &dwNumDevs, &dwLineAPIVersion, &LineInitializeExParams);
res = lineOpen(hLineApp, 0, &hLine, dwLineAPIVersion, 0, 0, LINECALLPRIVILEGE_MONITOR, 0, NULL);
return res;
}
HRESULT GsmControl::GsmLineUnregister()
{
res = lineUnregister(hLine);
// res = lineSetEquipmentState(hLine, LINEEQUIPSTATE_NOTXRX); /* Edit: This is commented out, as I don't want any kind of flightmode behaviour */
return res;
}
HRESULT GsmControl::GsmLineRegister()
{
// lineSetEquipmentState(hLine, LINEEQUIPSTATE_FULL); /* Edit: This is commented out, as I don't want any kind of flightmode behaviour */
res = lineRegister(hLine, LINEREGMODE_AUTOMATIC, NULL, 0);
if ( res != 0 ) //FAILED(res) )
{
errorMsg = TEXT("ERROR GsmLineRegister - lineRegister\n");
} else {
errorMsg = TEXT("SUCCESS GsmLineRegister - lineRegister");
}
return res;
}

Whats the return value of the lineUnregister() call?

Sorry, I have a problem getting the value. It's larger than zero.
Shouldn't the following code open a message window that says "GsmLineUnregister returned X"?
Code:
LPTSTR lpText = new WCHAR[1024];
swprintf(lpText, TEXT("GsmLineUnregister returned $d"), gsmCtrl->GsmLineUnregister());
MessageBox(NULL, lpText, TEXT("Deva Daemon"), MB_ICONINFORMATION);
Edit: I'm making too many mistakes lately. I also commented out lineSetEquipmentState, as that's how I want it to work but it doesn't (on a 9100)

OK, I've got it now. lineUnregister returns '11'.
Edit: It's not stable, it seems to return quite all kinds of values larger than ten. Each value is larger than its predecessor. After a reboot, I got a 12, and then again increasing numbers (19, 25, 29, 31). It doesn't seem to make any sense.
(Will I ever manage to write a post with no edits this week?)

WM6 - how to Query WLAN "connection" status

I am desperately trying to work around some unknown problem caused by our NDIS IM driver on WM6 and HTC TyTn ( TyTn at least, but most likely other devices as well ). I started some other threads regarding different facets of this problem, and no help is coming. Now I am just trying to work around it.
in short the problem is when power events happen the WLAN will never connect.
The work around is programmatically open the control panel with STControlPanel class and press the down button 1 time then the f1 key ( right dash ). This "presses connect" on the last configured access point. This works around my problem, however, I need to detect when the access point has connected. There is a "connecting" and "connected" message for the access point in this control panel dialog ( control panel # 17 ).
My Question: Is there some way to get this text "connecting" or "connected" from the control panel #17?
I have tried wzc, ndisuio, winsock, and other "non control panel" ways to detect connected state, but the IM problem fools all these methods. The only thing I have ever seen that successfully shows when the problem has occurred is the "connecting"/"connected" status in the control panel 17.
Please Help Someone.
p.s. If I can get this worked around, we sell a commercial grade ndis intermediate driver toolkit letting you easily write plugins without any of the hard driver details. We have redirectors, transparent proxy, tunnelers, virtual adapters, lots of good stuff. Also the same plugin will work on all windows desktop platforms vista - 98, WM5/6 and CE and also linux and solaris...

Custom ListView adapter repeats itself

I have a custom listview that pulls from an array, however when I reach a point that I have to scroll down to see more items, the items start to repeat themselves. According to the array, the items are fine and not repeating themselves, it looks like it's just the ListAdapter. Any help is greatly appreciated. I think the getView is really the only problem, but if you need other parts of the code, let me know.
Code:
public View getView(int position, View convertView, ViewGroup parent) {
ViewHolder holder;
if (convertView == null) {
convertView = mInflater.inflate(R.layout.list_item, parent, false);
holder = new ViewHolder();
holder.title = (TextView) convertView.findViewById(R.id.row_title);
holder.summary = (TextView) convertView.findViewById(R.id.row_summary);
holder.url = (TextView) convertView.findViewById(R.id.row_link);
convertView.setTag(holder);
String item = CurbAlert.listings[position];
item = item.replace("<br>", "");
String title = item.substring(item.indexOf("<title>") + 16, item.indexOf("</title>") - 3);
String summary = item.substring(item.indexOf("<description>") + 22, item.indexOf("</description>") - 3);
if (summary.length() > 100) { summary = summary.substring(0, 100); summary += "..."; }
holder.title.setText(title);
holder.summary.setText(summary);
holder.url.setText(item.substring(item.indexOf("<link>") + 6, item.indexOf("</link>")));
} else {
holder = (ViewHolder) convertView.getTag();
}
return convertView;
}

Try moving everything from line 10 to 17 inclusive until after the if-else statement. You want to setup the views even if you get your holder from getTag().

How to prevent laggy scrolling ListView w ImageView-Items filled with cached images?

Hello community,
I've got a ListActivity in my app, which shows Views including TextViews, for showing artist, title and album information of some mp3-Files (queried by my cursor), and an ImageView, for showing an albumart => Similar to the Tracklist in the music app.
Here's the code for my custom SimpleCursorAdapter and it's binding to the ListView:
Code:
void setListAdapterOverride() {
String[] fromColumns = new String[] {
AudioColumns.ARTIST,
MediaColumns.TITLE,
AudioColumns.ALBUM,
AudioColumns.ALBUM_ID
};
int[] toColumns = new int[] {
R.id.tv_artist,
R.id.tv_title,
R.id.tv_album,
R.id.iv_albumArt
};
cursorAdapter = new customAdapter(getBaseContext(), R.layout.listviewitem, cursor, fromColumns, toColumns);
setListAdapter(cursorAdapter);
if (MyDebug.Log)
Log.d("Activity", "ListAdapter gesetzt");
}
class customAdapter extends SimpleCursorAdapter {
int layout;
Cursor cursor;
String[] from;
int[] to;
public customAdapter(Context context, int layout, Cursor c,
String[] from, int[] to) {
super(context, layout, c, from, to);
this.layout = layout;
this.cursor = c;
this.from = from;
this.to = to;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
if (row == null) {
LayoutInflater inflater = getLayoutInflater();
row = inflater.inflate(R.layout.listviewitem, parent, false);
if (MyDebug.Log)
Log.d("Activity", "Inflate");
}
cursor.moveToPosition(position);
TextView artist = (TextView) row.findViewById(to[0]);
TextView title = (TextView) row.findViewById(to[1]);
TextView album = (TextView) row.findViewById(to[2]);
ImageView albumArt = (ImageView) row.findViewById(to[3]);
artist.setText(cursor.getString(cursor.getColumnIndex(from[0])));
title.setText(cursor.getString(cursor.getColumnIndex(from[1])));
album.setText(cursor.getString(cursor.getColumnIndex(from[2])));
Cursor albumArtCursor = contentResolver.query(MediaStore.Audio.Albums.EXTERNAL_CONTENT_URI, new String[] { MediaStore.Audio.Albums._ID, MediaStore.Audio.Albums.ALBUM_ART }, MediaStore.Audio.Albums._ID + "='" + cursor.getInt(cursor.getColumnIndex(from[3])) + "'", null, null);
albumArtCursor.moveToFirst();
String albumArtUri = albumArtCursor.getString(albumArtCursor.getColumnIndex(MediaStore.Audio.Albums.ALBUM_ART));
if (albumArtUri == null) albumArtUri = "default";
if (!imageCache.containsKey(albumArtUri)) {
Bitmap albumArtBitmap;
if (!albumArtUri.equals("default")) {
Options opts = new Options();
opts.inJustDecodeBounds = true;
BitmapFactory.decodeFile(albumArtUri, opts);
Integer[] bitmapSize = new Integer[] { opts.outWidth, opts.outHeight };
Integer scaleFactor = 1;
while ((bitmapSize[0]/2 > 50) && (bitmapSize[1]/2 > 50)) {
scaleFactor++;
bitmapSize[0] /= 2;
bitmapSize[1] /= 2;
}
opts = new Options();
opts.inSampleSize = scaleFactor;
albumArtBitmap = BitmapFactory.decodeFile(albumArtUri, opts);
} else {
albumArtBitmap = BitmapFactory.decodeResource(getResources(), R.drawable.ic_mp_song_list);
}
imageCache.put(albumArtUri, albumArtBitmap);
}
albumArt.setImageBitmap(imageCache.get(albumArtUri));
return row;
}
}
imageCache is a Hashmap<String, Bitmap> for caching the Bitmaps, so they don't have to be decoded from file again when they had been cached before.
In a former version of the code, I didn't have the imageCache, so the albumarts were decoded from file everytime a new row has been added. That slowed down ListView-scrolling. By adding the imageCache scrolling in ListView doesn't lag that much as before, but it's lagging a bit sometimes.
Can anyone help me to further optimize my code to completely prevent lagging when I scroll the ListView?
Thanks regards ChemDroid

[Q] How to stop the ball at touch release

hi, its killing me i can't fix it i made this thing because i was learning Canvas and drawing on android !
i included moving animations (smooth) but i removed it

}
}
the problem is my ball doesn't move at all, but i see the line, once i remove the line:
Code:
case MotionEvent.ACTION_UP:
ballSpeedX = 0;
ballSpeedY = 0;
it works, but you know, after release it continues with same speed :! its like the ACTION_UP is always the case, !!! any idea why it doesn't work, how to stop the ball once the user releases the screen?

also sorry if this is not the right place. i searched the forums, i got confused i didn't find anyplace to ask this question so i tough this is the best place!
