1. Yes (it coverts them)
2. Yes (but it may run a little sluggish)
3. No, only drive space.

I have VS2008 Express Editions running on a 1GB atom N270 netbook; yes, the CPU power is limited, however the limited screen size is my main concern for extensive work; such netbook is fine for applying code modifications in the field.

If you install SQL Server with it, it may take some memory if the server starts automatically. However, you can turn that off using the configuration manager.

hi, in cyber-cafe software I'm currently working on, I store order information in sql. There are some other information that needs to be stored (like; time,duration,price,cash,on/off,total charge AND configuration settings etc.) I look for the best practice without sacrificing the performance. Is the best place to store them Registry, Sql or other?
Thanks in advance

if its lan, saving it on sql won't hurt.
I have worked on wan operations. The only problem in lan connections happen when this lan is vpn.
|
|
|
|

I'have got nothing to do with lan fortunately, sql and my program will be on the same machine. So the thing I wonder is, is it ideal to store everything in sql or is there a rule that says; configuration settings should be kept in bla bla... and x information should be kept in.....
|

there is no rule. but you should consider scalability.
As you just mentioned, that your sql data would be on the same machine... in this case, even a file system could handle it. However, you chose sql because of future possibilities.
Similarly, to save configuration info, there are a few things that can be considered.
usually, configurations are of two types:
1) global - any changes affect all users.
2) local - any changes affect only current user.
global configurations are like rates, prices etc.. which are obvious to be common to all.
local are like colors, size, font, viewing preferences etc.
Now, global should be saved in sql as it has to be accessed by all.
local can be saved either in sql with a user_ID or can be saved in local user app data file. you can use Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData)
I personally prefer keeping everything in sql. any user can login from anywhere and have his configuration available.

Okay - Why? What is the purpose of your program? And how does the cyber café owner/management communicate with each individual machine about usage and who's assigned to it (or which access ticket is in use), etc.

We try to forget about those, and have decided to go with whatever works
I agree that a database would be the suitable place to store data on a network. If you don't have a server, I'd choose XML; gives you the advantage that you don't need to install SQL just for storing the application-settings, and you can edit it with any editor.
There's also INI-files, and yes, the registry is an option too, albeit one might need admin-rights to modify some keys. A nice option would be to store the settings online, so that they'll persist even after a reinstall.

I'd say that you should be storing this in the database (SQL Server). That way you can control configuration from a central location and the usuage data from the individual machines is also stored centrally. Remember you have to think of the performance of the administration side as well as the individual user side. The overhead of using a SQL server is minimal.
You also mention storing the information in the registry - How were you going to retrieve this information? While it might be a good location for some of the configuration information I don't think it is a good location for storing commerce information (price, usage times etc.)

You can use Application Settings (Project|Properties.)

hi guys...i have a problem as usual...actually an error that i have never seen before..i have two radio button in my form i use one of them to add customer and the second one to add company...while adding company no problem..i can make adding process..but while adding customer i have got an error on the screen by messagebox error says that :
"No mapping exists from object type System.Data.DataRowView to a known managed provider native type."
i have these codes to add the customer
cmd = new SqlCommand("insert into XXX(ad_syd,firma,sektor,grup,cep_no,is_no,ev_no) values (@ad_syd,@firma,@sektor,@grup,@cep_no,@is_no,@ev_no)", con);
cmd.Parameters.AddWithValue("@ad_syd",info.ToTitleCase(txtAdSyd.Text));
cmd.Parameters.AddWithValue("@firma", cmbFirma.SelectedItem);
cmd.Parameters.AddWithValue("@sektor", txtsektor.Text);
cmd.Parameters.AddWithValue("@grup", txtGrup.Text);
cmd.Parameters.AddWithValue("@cep_no", Birlestir(txtCepKod.Text, txtCep.Text));
cmd.Parameters.AddWithValue("@is_no", Birlestir(txtKod.Text, txtisTlf.Text));
cmd.Parameters.AddWithValue("@ev_no", Birlestir(txtEvKod.Text, txtEvTlf.Text));
if ((txtisTlf.Text != ""))
{
if ((txtAdSyd.Text != ""))
{
if (cmd.ExecuteNonQuery() == 1)
MessageBox.Show("Ekleme İşlemi Tamamlandı", "Uyarı", MessageBoxButtons.OK, MessageBoxIcon.Warning);
else
MessageBox.Show("Ekleme Sırasında Hata Oluştu", "Dikkat", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
else
MessageBox.Show("* İşaretli Alanlar Boş Bırakılamaz", "Uyarı", MessageBoxButtons.OK, MessageBoxIcon.Warning);
}
else
MessageBox.Show("* İşaretli Alanlar Boş Bırakılamaz", "Uyarı", MessageBoxButtons.OK, MessageBoxIcon.Warning);
i replaced a breakpoint but it doesnt enter if (cmd.ExecuteNonQuery() == 1) that line...it goes to catch block directly
what can be the problem ??

I can't see your code well as it misses formatting (read my sig!).
If you catch an exception, look at its ToString() information and you should be able to pinpoint the problem yourself.

would need a little more info... put a breakpoint in the beginning and then see where it throws the exception ie. move to catch block.
as you say that it doesn't enter (cmd.ExecuteNonQuery() == 1) there could be a problem with your stored procedure or method Birlestir.

At first glance, these if conditions appear to be the culprits (for your breakpoint not getting hit).

It seems like your code needs some cleanup.

hi guys thanks for replies....i think it gives that error because of the codes below
public void DosyaOku(object sender, EventArgs e)
{
StreamReader read = new StreamReader("Firmalar.txt");
string kelime = read.ReadLine();
while (kelime != null)
{
cmbFirma.Items.Add(kelime);
kelime = read.ReadLine();
}
read.Close();
}
because if i didnt work it the program doesnt give error..so what can i do now ??
bu arada simple data evet Türkiyede yaşıyorum ...bu arada kodda bi fazlalık mı var ??

Fazlalık yok ancak biraz toplarlamak lazım gibi.
