I find that hard to believe. Are you sure it's not Access?

For an SQL Server connection string, you specify the database name, not the path to the database file. The sole exception to that would be if you were using SQL Server Express.

Thanks Dave. This is the sole exception. I am using SQL Server Express 2008.

Set up an event in form2 that form1 subscribes to. Either pass the data via a custom EventArgs with the event, or via a property on form2.

I am seeking a way to Convert pixels to Twips ?
any good solution.
I have searched google but no used ans i get!

If you Bingle pixels to twips you will find loads of examples.
If you have done so and are unable convert the examples to C#, that is another matter.
Ask for help on the specific problems you are having and someone may be able to help you.

You stand corrected.

Hello,
I am developing a GMAO csharp smart device application.I am in the step of creating a checklist using checkbox tool added dynamically:
I have two tables:Travaux (Works in English) and Actions related by the two fields Nature (table Travaux)and typeTravail(Table Actions).If the user enters the number of the work(NBT the pk_Travaux),the system adds a number of checkboxs equal to the steps that should the user follows to accomplish(field step in Actions table).After that,the user has the possibility to check or not the step if he did it.All the traitments will be done dynamically with the database
My select statement is:
select Etape from Action where ((Travaux.NBT=textbox1.text) and (Travaux.Nature=Action.TypeTravail))
Equal of what this select returns,it will add dynamically checkboxs
I tried with this code but not working due to some errors 
private void button1_Click(object sender, EventArgs e)
{
string wCS = @"Data Source =\Storage Card\ModeDifféré\BaseGmaoLocale.sdf;";
SqlCeConnection sqlceconn = new SqlCeConnection(wCS);
SqlCeCommand command = sqlceconn.CreateCommand();
command.CommandText = "Select NBT, Nature from Travaux where NBT=@NBT ";
string s1 = textBox1.Text;
SqlCeParameter NBT = new SqlCeParameter("@NBT", SqlDbType.NVarChar);
NBT.Value = s1;
command.Parameters.Add(NBT);
SqlCeDataAdapter adapter = new SqlCeDataAdapter(command);
DataSet ds = new DataSet();
try
{
adapter.Fill(ds, "SQL Temp Table");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
foreach (DataRow da in adapter)
{ string s = adapter["Nature"]; }
if ((ds.Tables.Count > 0) && (ds.Tables["SQL Temp Table"] != null))
{
MessageBox.Show("Number of row(s) - " + ds.Tables["SQL Temp Table"].Rows.Count);
if (ds.Tables["SQL Temp Table"].Rows.Count > 0)
{
MessageBox.Show("Numéro de BT trouvé");
SqlCeCommand command1 = sqlceconn.CreateCommand();
command1.CommandText = "Select NoEtape, Etape from Travaux where TypeTravail=@typ ";
string s2 = textBox1.Text;
SqlCeParameter Typ = new SqlCeParameter("@Typ", SqlDbType.NVarChar);
Typ.Value = s2;
command1.Parameters.Add(Typ);
SqlCeDataAdapter adapt = new SqlCeDataAdapter(command1);
DataSet dat = new DataSet();
try
{
adapt.Fill(dat, "SQL Temp Table");
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
foreach (DataRow ligne in adapt.)
{
System.Console.WriteLine(adapt[0]);
}
}
else MessageBox.Show("Veuillez saisir un autre NBT");
}
adapter.Dispose();
sqlceconn.Dispose();
command.Dispose();
}
The errors are :
Error 1 foreach statement cannot operate on variables of type 'System.Data.SqlServerCe.SqlCeDataAdapter' because 'System.Data.SqlServerCe.SqlCeDataAdapter' does not contain a public definition for 'GetEnumerator' C:\Users\Admin\Documents\Visual Studio 2008\Projects\GMAOMobile\ModeDifféré\Travail.cs

Error 4 Cannot apply indexing with [] to an expression of type 'System.Data.SqlServerCe.SqlCeDataAdapter' C:\Users\Admin\Documents\Visual Studio 2008\Projects\GMAOMobile\ModeDifféré\Travail.cs
I wait for u help 
Thanks

Should be
foreach (DataRow da in ds.Tables[0].Rows)
{
string s = da["Nature"];
}

This should be

Hi,
Thanks Reddy,the errors disappears all with some corrections:
foreach (DataRow da in ds.Tables[0].Rows)
{
string s = da[0].ToString();}
.I want now to add every row it found after executing the select request:
command1.CommandText = "Select NoEtape, Etape from Action where TypeTravail=@typ ";
I create a listview and I wanna add like items every result of the select.I modify my code in his end like this:
............
foreach (DataRow dataRow in dat.Tables[0].Rows)
{
ListViewItem item = new ListViewItem();
item.Text = dataRow[0].ToString();
listView1.Items.Add(item);
System.Console.WriteLine(dataRow[0]);
}
}
else MessageBox.Show("Veuillez saisir un autre NBT");
}
adapter.Dispose();
sqlceconn.Dispose();
command.Dispose();
}
}
But this modification doesn't show any thing in the listviewitem.
Thanks a lot for u suggestions

Did you check if the DataTable has any rows after executing the select statement? Does it even get into the foreach loop?

Hi,
Thank u for u help.I found the solution using the listview tool(with its option checked) and all gets well.This is the link after that solved my issue:

Hi, I have the following string "455.56"
I want this to format in: 00455.5600.
I tried this and was expecting it to work fine: string strLong = String.Format(CultureInfo.InvariantCulture, "{0:00000.0000}", "455.66");
This statement results in: "455.66"!!
Why doesn't this work as expected? Other solutions?
thanks for your time.
Regards,
Jan

Try feeding it a number rather than a string...
string strLong = String.Format(CultureInfo.InvariantCulture, "{0:00000.0000}", 455.66);
The format info :00000.0000 is for numeric formats only: MSDN String.Format formats[^]
[edit]Should have explained the format is numeric... Oops![/edit]

Thanks for the answer, however
I did fed it a number also like this
String.Format(CultureInfo.InvariantCulture, "{0:00000.0000}", 455.66);
But the point is that the data to be formatted is in a string[] and even when I convert the string first to a double or whatever the result is the same, even the conversion is giving funky results: 45566 instead of 455.66!! I am not sure but I must be doing something stupid probably.

To do this while keeping it as a string will be messy:
string x = "456.78";
string[] parts = x.Split('.');
string whole = parts[0];
string decpart = parts[1];
string y = new string('0', 5 - whole.Length) + whole;
string z = decpart + new string('0', 4 - decpart.Length);
string padded = y + "." + z;
And that has no error checking!
To convert to double and back is probably the best way:
string x = "456.78";
double d = double.Parse(x, System.Globalization.CultureInfo.InvariantCulture);
string padded = string.Format("{0:00000.0000}", d);
But you will have to be absolutely sure that your number strings are all in "nnn.nn" format - remember that some cultures use "nnn,nn" which would bolox you right up! (That may be why your conversion gave funky results...)

I'd use a Regular Expression to perform the split.

I thought of doing it via Linq to SQL and a stored procedure, but decided it was too much typing...
