eVc++ DLL used on .NET? Error

Hello,
I have written a DLL on eVC++. And now I want to use this DLL in a .NET program. But by "Add Reference" I got an error, that says:
This is not a .NET assembly.
So my question is, is it possible to using a eVC++ DLL on .NET?
If yes, what should I do, and if not, is there another way to do with this problem?
Thanks all

Call Unmanaged Code. Part 1 - Simple DLLImport
By Vyacheslav Biktagirov
Managed world is beautiful, I have all classes I want in FrameWork.. But what if I want call some unmanaged code? For instance, I have DLL written in C++, and want use it from C#.
Let's look some code. Our DLL exports some function, in CDecl convention, that sums two integers:
extern "C" __declspec(dllexport) __cdecl int sum(int a,int b);
And, of course, we want reuse this code in C#. We must recall, that it is no "direct" way to call unmanaged code, but we must inform the compiler, what we want to call, how, and where is needed code located.
[DllImport("TestDll.dll", EntryPoint="sum",
ExactSpelling=false,CallingConvention=CallingConvention.Cdecl)]
static extern int sum(int a,int b);
and now we can call it like normal C# function.
x=5;
y=7;
z=sum(x,y); // x will receive 12
Here is full C# client code - tested for Beta2.

It sounds very simple, becouse "int" is isomorphic type, says, int in C# and ind C++ is identical. What we can do, when we want operate non-isomorhic types, like String? Recall, that .NET string is some Class, while C++ string is char*,or wchar_t*,or BSTR, .. String may be embedded in a structure, or pointed by pointer, or even something more exotic. Let's call some string function.
[DllImport("Advapi32.dll", EntryPoint="GetUserName", ExactSpelling=false,
SetLastError=true)]
static extern bool GetUserName(
[MarshalAs(UnmanagedType.LPArray)] byte[] lpBuffer,
[MarshalAs(UnmanagedType.LPArray)] Int32[] nSize );
This function receives two parameters: char* and int*. Becouse we must allocate char* buffer and receive string by pointer, we can't use UnmanagedType.LPStr attribute, so we pass ANSI string as byte array. int* is more simple-it's 1-element Int32 array. Let's call it:
private void button2_Click(object sender, System.EventArgs e)
{
byte[] str=new byte[20];
Int32[] len=new Int32[1];
len[0]=20;
GetUserName(str,len);
MessageBox.Show(System.Text.Encoding.ASCII.GetString(str));
}
We allocate 20 bytes for receiving ANSI string,one element in Int32 array, set 20 as max string length and call it. For receiving string from byte array I used Text.Encoding.ASCII class.

How SEUS Flashing Works

OK, so been trying to figure out what happens when you use SEUS.
It checks for internet connection by loading this URL:
Code:
http://emma.extranet.sonyericsson.com/ns/no-cache
I've figured out quite a bit.
Sony Ericsson has implemented something called Tampered Device Service.
This checks if the devices has been tampered with.
This service works from this server:
Code:
tds.sonyericsson.com
Then for the actual firmware download.
This is done by downloading 2 *.ser.gz which tells SEUS what Software customization to get and is sessions specific.
The customization ser.gz file looks something like this:
Code:
CDA=1233-7027_NjKhzOzTUsfXvPg40lyh6aTl.ser.gz
And it's downloaded from:
Code:
emma.extranet.sonyericsson.com
It's done via some sort of search mechanism on the server.
That looks like this:
Code:
ns/usdoe1/2/script/search/TAC8=35941903/CDA=1233-7027_By5JACZqd1R7JOpLu6qvwK8N.ser.gz
After that it's downloading the actual firmware files.
They are downloaded in bin format which I haven't been able to unpack yet.
They are also downloaded from the emma server and is named something like:
Code:
277795427_k9ABo3YVh+8klYUKwllGLDcJ.bin - ~14.3 MB
277835617_ZpJseUr9e09U5h2Cz81+5vcT.bin ~149 MB
Then it does a netbios call which has some sort of HEX code.
And then check the Internet connection again:
Code:
http://emma.extranet.sonyericsson.com/ns/no-cache
Now it starts up a service called:
Code:
/fq/ServiceClientDbServlet
This service runs from this server:
Code:
ma3.extranet.sonyericsson.com
This last part is done twice in a row.
Inside one of the *ser.gz files is a *.ser file which contains some code and instructions. Some parts is encrypted but most of the code is not.
See the complete code in post #2
I don't quite know what to do with all this info yet.
But hopefully something useful will come of this.
Just wanted to share a bit of my knowledge, hope it's useful for some of you here.

wow seems u done some packet sniffing...
may be u should contact Bin4ry regarding this... he is involved in FreeXperia Project for Arc/Play...
i am sure he can shed some more light on this matter...

Figured out the *.bin files is the actual files that also goes in the blob_fs folder:
Code:
%programfiles%\Sony Ericsson\Update Service\db\
So they are decryptable using the known method.

Tampered Device Service does in fact check for Root and custom software.
Don't know if this will have an effect in the updating process from SEUS.

So, it's a bad news huh. Keep looking. Thanks for the info.
Sent from my X10i using XDA App

Confirmed that devices that has been rooted and modified in software will not be eligible for 2.3.3 update. You will have to flash back a stock unrooted firmware before updating to 2.3.3

Of course. SE said that in their blog. Better backup all data in SD Card and format it too. I don't think the SEUS' intelligent enough to check out that the SD Card contains CyanogenMod folder as busybox and xRecovery
EDIT: I tried to find the update 2.1 package in my computer after repaired my phone for several times and I can't find it. It's of course that it's deleted as soon as the update completed.

I believe SEUS works like the Flash Tool and Pay-Per-Update service through fastgsm.com and davince.
Flash Tool requires you to provide the firmware and place the sin files in the correct location.
Pay service requires a fee to install the correct sin files/firmware.
SEUS requires a CDA to determine which sin files/firmware to install.

I beg that the FlashTool works like SEUS cause without SEUS and other update services, where is FlashTool come from?

But what if SEUS change its method? Well, i still want to update and we will see how it goes.
Sent from my X10i using XDA App

Whatever method they choose, they can't close the door behind them. They need the access too. Flash Tool can be updated.
Nor would google allow that. JMHO

Yes, FT can be updated but it's development is kinda dead as of now, and we don't even have its source codes, so the other developers can't update it. Unless if Androxyde and Bin4ry want to work on FT again.

Why are the devs acting like this is an issue? The Flash Tool already works on the ARC, so what are you worried about?

Work on Arc no mean it can work on X10, just like Arc has bootloader unlocked but no mean X10 can when update to 2.3.3

You totally missed the point. The bootloader or root has NEVER mattered. When the NEVER has happened, then start your *****ing.

What I mean is that IF SE changed their flashing method for the GB firmware and FT won't work for those who upgraded their X10 to GB. But another user has said that they won't since it requires them to start all over again.
Who knows, we're not the one who are developing the firmwares and we all should stop making assumptions(but some people aren't making assumptions, they are so sure they are right).

I am not pretending to know. However, you are failing to acknowledge that the Flash Tool is a modification of Update Service. The same method is used. Quit acting like this is nuclear science.

I told you, what IF they CHANGE the flashing method, then SEUS will also be updated with the new method.
Why am I repeating this anyway? Silly me.

[Q] Selecting Text from a TextView for GingerBread

I would like to select text from a textview,partially that is for Gingerbread as well as higher platforms,I find that android:textIsSelectable is not available and the WebView workaround only does it for complete text,I have tried to use pre-baked code to do this by extending a TextView:

txt_copyFrom.setCursorVisible(true);
txt_copyFrom.setEnabled(true);
txt_copyFrom.setTextIsSelectable(true);
txt_copyFrom.setOnLongClickListener(new OnLongClickListener(){
@override

int start=txt_copyFrom.getSelectionStart();
int end=txt_copyFrom.getSelectionEnd();
if(start>end)
{
//I guess the SelectableTextView fixes this:
start=start+end;
end=start=end;
start=start-end;
}
mSelectedText=txt_copyFrom.getText().toString().substring(start, end);
Log.d(TAG, "Selected text: "+mSelectedText);
return true;
}});
I get a StackOverflowError:

This is followed by:

This is,as expected: clean();
Then this occurs repeatedly:
AndroidRuntime(12712): at com.example.clipboardtest.SelectableTextView$2.onTouch(SelectableTextView.java:120)
which is `lastOnTouch.onTouch(v, event);`
I guess this is because we retain the OnLongClick and OnTouchListener.
Also the code calls for selection of stuff using a background colour and foreground color:
SpannableStringBuilder sb = new SpannableStringBuilder(text);
BackgroundColorSpan bgc = new BackgroundColorSpan(_SelectedBackgroundColor);
ForegroundColorSpan textColor = new ForegroundColorSpan(_SelectedTextColor);
sb.setSpan(bgc, start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
sb.setSpan(textColor, start, end, Spannable.SPAN_INCLUSIVE_INCLUSIVE);
setText(this);
I do not understand why this implementation does not chain to the superclass implementation like I specifically asked it to.Is there anything else I can do,any approach I can follow to make it work,is there a pre-implemented version I can use.If there is nothing can you guide me through implementing a custom TextView for Android

[Q] Can I register a listener on process state?

I'm an experienced developer but new to Android development. I have an app that runs some native binaries, and I provide a status indicator to show when the native process is running and when it's not. Currently I poll the device to figure this out, using the ActivityManager API to determine if specific processes are running or not.
I'm hoping there is some way to register a listener on process state changes, so I can get notified when my process starts or stops. I looked through the API, and there doesn't seem to be such a thing. Does anyone know how I can keep track of process start and stop other than polling via ActivityManager?

Afaik there's no way to accomplish that other than your way or being system/root app. See this similar question here for reference.

Can you show how you start the process?

Sure. Here's the class that manages starting, stopping, and statusing (running or not) the binary executable. In this case, it's the omniNames service of the omni ORB (CORBA broker).

Here's the script that startOminNames() invokes. It's the shell script installed with omniORB with functions other than start and get_pid removed, since those are handled by Android classes. You can invoke any executable in place of the script, or wrap your executable in a script.
Code:
#
# omniNames init file for starting up the OMNI Naming service
#
# chkconfig: - 20 80
# description: Starts and stops the OMNI Naming service
#
exec="/sdcard/data/com.axiosengineering.rhmanager/omniORB/bin/omniNames"
prog="omniNames"
logdir="/sdcard/data/com.axiosengineering.rhmanager/omniORB/logs"
logfile="/sdcard/data/com.axiosengineering.rhmanager/omniORB/logs/omninames-localhost.err.log"
options=" -start -always -logdir $logdir -errlog $logfile"
start() {
#[ -x $exec ] || exit 5
echo -n $"Starting $prog: "
$exec $options
}
get_pid() {
ps | grep omniNames
}
case "$1" in
start)
start && exit 0
$1

pid)
get_pid

*)
echo $"Usage: $0 {start|stop|status|restart|condrestart|try-restart|reload|force-reload}"
exit 2
esac
exit $?
And here's the IStatusListener interface
Code:
public interface IStatusListener {
public void running(boolean running);
}
Runtime.exec() has some pitfalls. See this helpful Runtime.exec tutorial for a nice explanation.

( Volley > sending GET Request with parameters ) How to flatten Map<String,String> pa
I got this custom volley request class that extends Request with the request parameters in Map<String,String> format, my question is how to flatten Map<String,String> parameters correctly into a query string and receive it with PHP $_GET?
Code:
public class GsonGetRequest_Exp5<T> extends Request<T> {
private Response.Listener<T> listener;
private Map<String, String> params;
private Type type;
private Gson gson;
public GsonGetRequest_Exp5(String url, Map<String, String> params, Type type, Gson gson,
Response.Listener<T> reponseListener, Response.ErrorListener errorListener) {
super(Method.GET, url, errorListener);
this.type = type;
this.gson = gson;
this.listener = reponseListener;
this.params = params;
}
public GsonGetRequest_Exp5(int method, String url, Map<String, String> params, Type type, Gson gson,
Response.Listener<T> reponseListener, Response.ErrorListener errorListener) {
super(method, url, errorListener);
this.type = type;
this.gson = gson;
this.listener = reponseListener;
this.params = params;
}
@Override
protected Map<String, String> getParams() throws com.android.volley.AuthFailureError {
return params;
};
@Override
protected void deliverResponse(T response) {
listener.onResponse(response);
}
@Override
protected Response<T> parseNetworkResponse(NetworkResponse response) {
try {
String jsonString = new String(response.data,
HttpHeaderParser.parseCharset(response.headers));
return (Response<T>) Response.success
(
gson.fromJson(jsonString, type),
HttpHeaderParser.parseCacheHeaders(response)
);
} catch (UnsupportedEncodingException e) {
return Response.error(new ParseError(e));
} catch (JsonSyntaxException je) {
return Response.error(new ParseError(je));
}
}
}
Code:
public static GsonGetRequest_Exp5<ArrayList<FeedObject>> gsonGetRequest_exp6
(
Response.Listener<ArrayList<FeedObject>> listener,
Response.ErrorListener errorListener,
String str
)
{
//final String url = "example.com/php.php";
final Map<String, String> params = new HashMap<String, String>();
final Gson gson = new GsonBuilder()
.registerTypeAdapter(FeedObject.class, new FeedObjectDeserializer())
.create();
String test_url = "example.com/php.php";
params.put("SearchKey", str);
StringBuilder builder = new StringBuilder();
for (String key : params.keySet())
{
Object value = params.get(key);
if (value != null)
{
try
{
value = URLEncoder.encode(String.valueOf(value), HTTP.UTF_8);
if (builder.length() > 0)
builder.append("&");
builder.append(key).append("=").append(value);
}
catch (UnsupportedEncodingException e)
{
}
}
}
test_url += "?" + builder.toString();
return new GsonGetRequest_Exp5
(
test_url,
params,
new TypeToken<ArrayList<FeedObject>>() {}.getType(),
gson,
listener,
errorListener
);
}
problem with my code is, the "params" I keep getting "null", nothing is added to the end of my example.com url, can anyone point out what I did wrong?
