We really can't answer that: we have no idea of what your project is, what environment it will run in, or what kinds of data you are handling. "Security" in this context could mean anything from strong encryption, to hashing, to "doing proper backups".
Since the term "security" will vary depending on all of those, we just don't have anywhere near enough information to begin answering.

I am capturing rtp packets from my computer and am trying to recover the audio package. The G729 codec is broadcast, I'm trying to capture audio, but it is not timing.
Example - Real Call
Line 1: ----Hi------two--------four-------six-------eight------ten
Line 2: Hi------One------three------five-----seven-------nine
My record file:
----Hi------two-----four-------six------eight------ten
Hi--one---three---five----seven---nine

|
Very interesting but it explains very little, please explain in proper detail what assistance you require.
|
|
|
|
|
I'm traveling the RTP buffer and retrieving the audio, I have realized that the lack of synchronization is related to the number of samples of silence.
|
|
|
|
|
Is there some compression issue? Silence can be compressed easily, while actual audio are hard to compress.

How to display records from database between two dates using calender control
|
|
|
|
|
You're probably going to need two calendars - one to identify the start date and one to identify the end date. Once the user has chosen the dates (make sure that the before isn't after the end date), issue a query to the database selecting values between the two dates. As you have given us no other information to go on, this is as close to an answer as you are going to get.

Please don't concatonate SQL Strings this will leave you open to SQL Injection. Read up on Parameterised Queries.

Please also explain the problems with selecting "all", as opposed to what you need. And that the empty event should be removed. And why we dispose things. And..

And also the unnecessary use of global variables, when they could more than likely be better at method level? so I also add that to my list  .
For me the concatinated SQL String just jumped straight out at me.
but to your question I would suggest the OP also have a read of this Is using COUNT(*) or SELECT * a good idea?[^] The first answer is a good read.

It does, but that doesn't justify a hit-and-run post

COUNTing all records is not a column-wise operation - it won't be pulling a large blob that has been added last month from the db that travels over the network.

Generally it is expected that you include the exact problem and what you have done so far to solve it.
It's good that you state what you want to achieve, but without more information the answer could possibly be too extensive to write down.

Trying to learn LinqToSQL... I have this query working in SQL...
Table1 = 0,1,2,3,4 (enum table)
Table2 = abc 0 data
abc 2 data
abc 3 data
def 1 data
def 2 data
so Table1 is an enum table. Table2 contains the data. For state 'abc' for example, I have data defined for levels 0,2,3. For state 'def' I have data defined for levels 1,2.
What I want is:
abc 0 data
abc 1 null
abc 2 data
abc 3 data
abc 4 null
def 0 null
.
.
.
etc. A sort of report.
What would be a good way to generate the report in LINQ to SQL? My concept in SQL is to do:
select distinct Table1 cross join Table2 left join Table2
so I first get all combinations of state x level and then left join against Table2 again to get the data (and allow nulls for situations where Table2 doesn't have data for the specific state x level.
Not sure if there is a cooler way to do this in linq?
I found a sql to linq converter, but it didn't support cross joins  ..

There is a LINQ forum just below here.

My web project is using interop to create word document. It works on my system since i have word installed on my system but Server does not have office installed so
How can i install Office.Interop.WOrd assembly on server.
Should i just copy the interop dll and register it or is there a setup i have to do?
|
|
|
|
|
Installing the interop assembly on the server won't help. If the server doesn't have Office installed, you can't use Office on the server.
Also, using Office interop from an ASP.NET application is not supported, and will most likely fail in interesting ways:
Microsoft does not currently recommend, and does not support, Automation of Microsoft Office applications from any unattended, non-interactive client application or component (including ASP, ASP.NET, DCOM, and NT Services), because Office may exhibit unstable behavior and/or deadlock when Office is run in this environment.
You would do better to use a supported solution, such as the Open XML SDK[^], or DocX[^].
There's even an article introducing DocX here on CodeProject: C#: Create and Manipulate Word Documents Programmatically Using DocX[^]

So you have an X-Y-problem: you want to do X, think of a way you can solve, get stuck with that way, and now you ask us about that (wrong) way...
Ask the correct question!

yes i was asking the wrong way to do it.

As far as I am aware, you can;t do that - it is a breach of your licencing conditions, unless you purchase a copy of Office to install on the server.
And if your server is run by a web hosting company, they might want to be involved in that - and would probably not be happy if you just add copyrighted assemblies to their equipment!
