No, because we do not do your work for you.
If you want other people to do your job, you have to pay. I suggest you go to vWorker (or whatever it is called this week) and try there. But be aware: pay peanuts, get monkeys...

I think that's normal: helping others if we can, i don't ask to do my job.
I asked for suggestion, for real time application.
private void DoMainLoop(Image<Bgr, Byte> frame)
{
try
{
Stopwatch watch = Stopwatch.StartNew();
Image<Gray, Byte> img1 = frame.Convert<Gray, Byte>();
if (traiter)
{
img1 = img1.SmoothBlur(smooth, smooth);
img1 = img1.Dilate(dilate);
img1 = img1.Erode(erode);
}
imgBin = img1.ThresholdBinaryInv(new Gray(threshold), new Gray(255));
handrectangle = HandsFromContours(imgBin);
......
......
......
}
}
what i want is a suggestion of a segmentation in real time in place of getting the hand from contour.

No, you asked for the code, not a suggestion.

Perhaps you need to phrase things differently?

You shouldn't try to use colour segmentation to do this - it's just too fraught with issues to be able to handle this effectively in real time.

What should i use for a rapid segmentation of the hand in a relative simple background ?

Hi,
We have 2 services running in the same server. Both the services are using different Excel templates(Macro enabled) from different folders.
The issue is, when these 2 services are processing the request at the same time, i am getting this 'RPC server unavailable' error.
What is the cause for this issue? how one service doing excel processing causes RPC server unavailable in the other service.
Pls. help.

That's a COM error message meaning that the other application has crashed.
Try different users for running the services.

Hi,
Thanks for your reply.
Already these services are running as different users.
One as SYSTEM and the other as <some user="">.
Pls. guide me why one service is crashing the other.
Info - Both Excels are having macros.

Hello everyone. i am developing Calls recording application in C#. which allow me to record my Conversation. Recording part is complete and my recording is saving in MP3 Format.
Now i want to some other features with my MP# file.
1. Firstly i want to implement an algorithm to verify that a file has been created by my system(my Hardware/Software) or not.
2. I have to add my company slogan with my MP3 file data as my signature. such that if anyone ask me about the conversation file and if he/she makes changes in file so we can verify that file is changed or not.
(I am doing now by checking MD5 signature of file that file is changed or not. but its not giving me the perfect location that from where to where file has been changed.)
If anyone have any idea about this then please help me that how can i achieve it.

edit, August 31, 2013: you should definitely search CodeProject: it was easy to find this [^], and this [^] ... which seem, to me, immediately relevant to your goals here.
I assume the constraint here is: you must have a playable, valid, .mp3 file: correct ?
2. have you thoroughly investigated the general issue of metadata in .mp3 files, and such resources as the ID3 format [^], and tools like: [^].
3. what is your standard for "non-hackability" here ? are you willing to go as far as to actually modify the digital values that represent the waveforms of the recorded audio itself, the audio equivalent of "secret watermarking" a bunch-of-pixels in-a-file ? is it your intent to have something that could actually be introduced as "provably" from a certain source, in a court-of-law, when its authenticity is challenged by "expert witnesses" ?
4. what have you tried so far ? have you solved the problem of generating a unique ID based on your hardware and software ?
5. have you definitely excluded the possibility the existing standards for metadata in .mp3 files offer you enough "bytes" to store all the things you describe you wish to store, in the file ?

for (int i = 0; i < cbLengend.Items.Count; i++)
{

}
}
}
So on our solutions we don't want to call the stored procedure again, because they return 25k rows, over crosstab and mixed select, that take for first time around 5 seconds.
We define the DataTable dt = new DataTable(); for keep the data over all postback message we got from html, but is not working as we want. Also, for Chart and CheckBox.
can any give the path how to solve this?
 
Thanks for any advice and any answer

You need to read the ASP.NET Page Life Cycle[^]. In particular, note that a new instance of the page class is created to serve each request. Field values will not be preserved between the initial request and the post-back request. Dynamically created controls must be re-created on every request.
If you want to keep the DataTable alive across requests, you'll need to store it in the Session or the Cache. However, since you say it contains 25K rows, this will put a lot of memory pressure on the server, and could lead to other problems.
private void Page_Init(object sender, EventArgs e)
{
LoadTable();
}
private DataTable LoadChartData()
{
const string cacheKey = "Testing_Studies_GraficosDados:ChartData";
var result = (DataTable)Cache[cacheKey];
if (result == null)
{
string[] InValues = new string[] { "2013-08-26 00:00", "2013-08-28 23:59", "2", "50" };
var log = new IOHelper();
log.OnInfo(string.Format("Begin={0}\tEnd={1}\tTT_Id={2}\tpggrel_id={3}", InValues[0], InValues[1], InValues[2], InValues[3]));
result = SQL.execStroredProcedures("EAPMSDAT", "wwGetDataForGraph", InValues);
Cache.Add(cacheKey, result,
null,
DateTime.UtcNow.AddMinutes(5),
Cache.NoSlidingExpiration,
CacheItemPriority.High,
null);
}
return result;
}
private void LoadTable()
{
DataTable dt = LoadChartData();
PopulateChart(dt);
}
private void PopulateChart(DataTable dt)
{
var C1 = new Chart();
var cbLengend = new CheckBoxList();
...
}

It's a fairly simple change:
private DataTable LoadChartData()
{
const string cacheKey = "Testing_Studies_GraficosDados:ChartData";
var result = (DataTable)Session[cacheKey];
if (result == null)
{
string[] InValues = new string[] { "2013-08-26 00:00", "2013-08-28 23:59", "2", "50" };
var log = new IOHelper();
log.OnInfo(string.Format("Begin={0}\tEnd={1}\tTT_Id={2}\tpggrel_id={3}", InValues[0], InValues[1], InValues[2], InValues[3]));
result = SQL.execStroredProcedures("EAPMSDAT", "wwGetDataForGraph", InValues);
Session[cacheKey] = result;
}
return result;
}

You can hook events OnLoad() and still have access to session and ViewState.
But, from my experience Dynamic controls can be a night mirror, so being new to dotnet you may want to look at other options to do what you are trying to do..
Like Repeater Control, ListView, etc.
Also, your control ID is very important..
If you generating controls for example each time you generate them if you want them to keep their ViewState data then you must assign them the same ID they where on the prev postback.
I have often implemented a list type of viewstate where I can add all the controls there..
But, then you also run into a lot of problems with this too...
IE, Rendering.. etc.... life cycle hell..
So, I would see if the build in controls will do what you want before going down the dynamic path of life cycle hell.
I also want to add you can use viewstate, its often better to use then sessions for passing simple postbacks.
Good luck my friend... its a scary path..

Why not define a limit of rows to return?, for example 1000. If the user wants to find more specific information should use filters.
That will avoid a large consume of memory due storing 25k rows on cache and the requests to database will take less time to process.

What is SMDR?
Veni, vidi, abiit domum
|
|
|
|
|
SMDR is an abbreviation for station message-detail recording.
Regardless of their size, most telephone systems output Call Detail Records (CDR). Generally, these are created at the end of a call. But on some phone systems, the data is available during the call. This data is output from the phone system by a serial link known as the Station Message Detail Recording port (SMDR).
Some of the details included in call records are: Time, Date, Call Duration, Number dialed, Caller ID information, Extension, Line/trunk location, Cost, Call completion status.

But if we need to use session, because the InValues can be different by users, so in that case we had to change to session.
