Hello,

I am building C# desktop application (client) that will connect to SQL Server on remote machine.
There will be many clients connecting to the database at the same time.

What do you advise me to do?

a) Schould every client connect directly to the remote SQL server?
b) Should I create some middle-tier between application and the SQL server, for example some webservice?
If yes, whats the best way to communicate between the middle tier and the client? SOAP?

I'm just new to .NET and I wonder what are drawbacks of either approach. The most important thing for me
is simplicity of the solution , I need to finish thins app as soon as possible.

Thanx Smile | :)

For an internal app, I generally just connect to the database from the client.

Take a look at this[^].

and
Image Recognition with Neural Networks[^], this one is from here on CP, although it is not strictly about facial recognition.

This is not an easy subject, so good luck. Smile | :)

I think it is, but then I'm not that good at Graphicsy type things. Smile | :)

There is a lot of work going on in the field, but finding easily understood articles on it is not so simple.

I'll probably get a handle on it eventually, I tend to absorb things like that over time, until the little light bulb comes on, then I'm OK.

Hey buddies ,..... i am working on C# Socket programming .... but i got a reference abt socket programmin in Java ............. and I got this word .... "THE JAVA MEDIA FRAMEWORK (JMF)" can any body tell me its equivalent in c#.....Thank you.

System.Net.Sockets namespace. Well, it's not really the equivalent but it is where sockets live.

Just google c# sockets, loads and loads of help.

OMG .... I am trying to work using System.Net.Sockets ... but I thought it will have another namespace ... So is that means the Java functios will have an equivalent in C# too ...Thank you budy ...........

The biggest problem in trying to use Java stuff/terms in .net and the other way round, is that they dont always have the same technologies grouped into the same libraries.

I can't think of an example off the top of my head, but you will almost certainly find some socket related things from the JMF that aren't in the System.Net.Sockets namespace. Conversely some things in the System.Net.Sockets namespace won't be in the JMF.

So in this instance when you find one of these problems, get your google-fu working. Smile | :)

    Environment.GetFolderPath(Environment.SpecialFolder.MyPictures));
bitmap.Save(fullPath);

So you decided on cheating all the time, hoping to have a slightly better chance of being the first at it?

Next people will start and claim it is my fault the average reply quality is going down...

I should have put a joke icon on that post Luc, I don't take it that seriously. If someone else answers a question that's great, so long as the OP gets the correct answer which this time he did - twice.

In this case I read the Subject 'Create a bmp' and read in the post '1 x 1' so went ahead and answered. I then reread the question (as I always do to make sure I have given the fullest answer I can) and noticed he wanted a bitmap file so I modified my post to show how to save it to a file. In the minute or so whilst I modified my post, Henry had posted his answer.

No cheating, no battle field - and all in good spirits trying to help the OP from me and Henry Big Grin | :-D

This sounds as if it could be for something naughty.
But I don't care, today, so:

BitMap bm = new BitMap(1, 1);
bm.Save("C:\Windows\Temp\NefariousBitmap.bmp");

I am needing this to prevent MS Access from bringing up it's splash screen when ms access loads.
Since you need to place a bmp file in the same directory as the mdb file with the file names being the same just the extensions different.

Using my application to open a file

I have developed an application that works with xml files. I have allowed users to open an xml file with my application. This I have done using the Main(String [] args) function. But the problem is the application name is not being displayed along with the application icon when the user right-clicks and chooses "Open With" in windows explorer. Would I need to make any registry entries for this to happen, or is it something I can do within the application itself? I'm currently working with the Microsoft Visual Studio .NET 2003 IDE. Please help.
