Use INotifyPropertyChanged in your property fields, and react to the change. If you take a look for an article on binding by Paul Stovell on using databinding in Windows Forms then you can find an example suitable for your needs.

Hi gurus,
I would like to know how it is possible to insert in a combo box the text values of an enumeration object?
For example, consider the SymbolType enum object from ZedGraph.
I would like to browse the enumeration values and add them in a combo box in order to give to the user the possibility to select the symbol for the curve.
I hope my question is clear enough.
Best regards.
Fred.

Use Enum.GetNames(typeof(SymbolType)) to get the names of the constants.
Despite everything, the person most likely to be fooling you next is yourself.

Hi All,
I have a datatable :
id name duration
01 001 00:10
02 002 00:20
03 003 00:10
As you can see, rows 0 and 2 have the same duration: 00:10
Now how can i make a algorimte to remove all those rows(except ONE of those rows) that has the same duration from my datatable ?
Thanx.

Hi,
perhaps the easiest way is to sort your datatable by duration using Select method and then iterate the results and delete the duplicate durations.
Hope this helps,
Mika
|
|
|
|
|
Group by duration and use min(id) to get one of the records to keep, and use having to get the ones where count(*) > 1. Now join this result in a delete on the table, and specify the ones where id is different and duration is the same.
Despite everything, the person most likely to be fooling you next is yourself.

I have made a project in which i have generated a report with the help of data in the database. Now I need to print the report but I don't know how to include and print a *.doc extension file through the project.Please help me......
|
|
|
|
|
1. save your report from database in temporary file and give extension .doc i.e: c:\temp\abcd.doc
2. call ShellExecute with parameter 'print' instead of 'open' (please read documentation about calling winapi method)
requirement : ms word
hope it helps

Hi,
you don't really need ShellExecute and WinApi; the Process class and ProcessStartInfo.Verb offer
the required functionality.

thanks fyi

Heyho SeeSharp PPL,
I have a question, for status connection:
private void button2_Click(object sender, EventArgs e)<br />
{<br />
string MyConString = "SERVER=" + WheRe + ";DATABASE=" + dB + ";UID=" + aCC + ";PASSWORD=" + Pw + ";";<br />
MySqlConnection connection = new MySqlConnection(MyConString);<br />
<br />
if (connection.State == ConnectionState.Closed)<br />
{<br />
string code = "Connection failed!";<br />
}<br />
else<br />
{<br />
string code = "Connection successful!";<br />
}<br />
<br />
<br />
System.Windows.Forms.MessageBox.Show(this, code);<br />
connection.Close();<br />
this.Close();<br />
}
How can i make the if statement to work it does show me anny errors.. and it doesnt work like i want it todo.. 
Anny one? =)

Hi,
Can't see any call to Open method so the connection will not be established. Try adding it before investigating connection state.
Also keep in mind that a connection has several possible states.
Mika
|
|
|
|
|
use System.Data.OleDb.ConnectionState.State (while using ACCESS data base or use accordingly).
|
|
|
|
|
When you open the connection, it will throw an exception if the connection fails.
Despite everything, the person most likely to be fooling you next is yourself.
|
|
|
|
|
im not sure but, im looking for a sample piece for the statement..
Can some give me a sample?
|
|
|
|
|
...
MySqlConnection connection = new MySqlConnection(MyConString);
try {
connection.Open();
System.Windows.Forms.MessageBox.Show(this, "Connection state is now " + connection.State);
connection.Close();
} catch (System.Exception exception) {
System.Windows.Forms.MessageBox.Show(this, "Connection failed:\n\n" + exception.Message);
} finally {
this.Close();
}
Was this what you were looking for?
Mika

Hi All,
Im using a string to select some rows from my datatable:
string expression;
expression = "Act = '001' ";
DataRow[] foundRowsq;
foundRowsq = dtPar.Select(expression);
Now how can i the not equal token in my expression? when i doe this im getting a error:
expression = "Act != '001' ";
So what should i use instead of != ?
Thanx.

Try <> instead of !=
