Hi All
I have loaded 3tabes to my application. after the work is done, I wasnt to save it all.
using foreach(is there a better way?) I recreated from my different class objects 3 datatables.
now I have the tables, I think I added them to new ds
DataSet ds= new DataSet();
ds.Tables.Add(emp);
ds.Tables.Add(managers);
ds.Tables.Add(empToManagers);
did I do it write?
no my main question: in my db , I have 3 tables. some of the lines has been changed, deleted or some lines are new. what is the best way to update the db, without checking every line my self, I tried and got lost with the sql.
someone tokd me I can use adapter, but how?
(when I open th data, It is easy to se adapter
public DataSet GetDataSet(string tblName, string sql, DataSet ds)
{
adapter.SelectCommand.CommandText = sql;
adapter.Fill(ds, tblName);
return ds;
}
)
tnx

Simple answer, you don't. The database actually stores the date (and time) as a number, not in any format. You need to do the formatting within your application.

Dates don't have a specific format.
One simply writes the value "as date" to a "date field" in the database. It will be saved in a format-independent way. It's formatted as soon as you look at it. Thus, you should format the data after reading from the database, as soon as you display it.

No. I'm not trying to be cruel to you here, but this is for you to do, and it has to be something that engages your interest and you are capable of completing. I don't know you, so I can't offer any sensible advice on a topic that will keep you motivated when developing, and I don't know what level the BTECH is aimed at, so I can't judge the skill level that will be required.
If I was to suggest something that was too basic, you could end up failing because it's too shallow, and if I suggest something that's too complex, then you won't complete it and you'll fail. Either way, I've done you no favours.
If I were you, I'd look for something that interests you, and that you have sufficient knowledge in already that you don't have to waste unnecessary time researching the topic beforehand.

I know what would be really useful..
An image process application that handles live video stream from any source. Your application will then be able to detect the face of any person in shot and then identify that person by comparing data with a database. This database should contain information stating the security threat of each person and an alert should be made when a person with a high security threat is detected.
Additional, any data detected that is not present in the database should be stored along with a flag that allows a user to go though a list of unidentified people and then choose a further action to take such as providing a name for the person etc.
When you have finished, make sure you create an article on it and submit the source for all to use.
Good Luck!

For the win, you could call it the "Technological Empirical Real-time Radical Identification, Sensoring and Trapping System". or TERRISTS for short.

hi
what is the best and the short way to limit textbox for only numbers
(in C#)
thank's
|

Make a usercontrol and restrict user to type alphas..amd use it wherever u want..

It depends on what you mean by only numbers. I wrote this one[^], it allows digits only - no negative sign, number separators, currency symbols... just numbers
|
|
|
|
|
Since they're so commonly needed, I have a handy collection of things like signed int, unsigned int, signed float, unsigned float, which do all the validation needed. (Unfortunately it's company code, so I can't give you the source, but they're based on similar ideas to the article linked above.)
It's definitely worth making these once so you'll never be stuck for one again.

If this is already running, you can change the startup mode from Service Windows [ Run > Services.msc ].
If you want to change it in you code, You have to change the StartUp Type of of your Service Installer.
serviceInstaller1.StartType = System.ServiceProcess.ServiceStartMode.Automatic;

Thanks for reply

My need is i want to change the already installed services , for example windows services are installed with default value . i want to change them .. hope you got my question

That I have already mentioned to you.
Start > Run > Services.msc> Right Click on The Services > Change the Startup Mode.
If you have to code, then you need to change and reinstall the service again !

You could try by changing the Start value in the registry for your service (though I haven't tried this myself, but I figure it would work).
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\ServiceName\
Start REG_DWORD (2) <- Change this value to either:
2 = Automatic
3 = Manual
4 = Disabled

Would it be any problem if we change it from Service Console ?

Serialisation is binary, not XML, AFAIK. I don't know if you can automatically have it done to XML, or if you need to write your own code.
