In your Form1_Load() handler, add this line just before returning from the method:
this.Controls.Add (MaLV); /ravi

Hi,
I don't understand u meaning,sorry"just before returning from the method"
Thank u if u give me u code.

If you don't understand the phrase "just before returning from the method", I respectfully suggest you spend some time learning the basic concepts of programming before venturing to write code.

Hi,
Thank u for u advice.I wanna tell u that is not a problem of learning programming,it is a problem of langage.I wanna tell u that in Tunisia,we study our subjetcs including informatic with French langage so there is a difficulty of langage.I will be grantful for u to understand my situation
Thank u

What I meant was, "dans votre Form1_Load procédure, ajoutez la ligne juste avant le retour". Sorry, I can't do any better.

You're not seeing the items because you haven't added any columns to your list view.
private void Form1_Load(object sender, EventArgs e)
{
ListView MaLV = new ListView();
MaLV.Parent = this;
MaLV.Dock = DockStyle.Fill;
MaLV.View = View.Details;
ColumnHeader ch = new ColumnHeader();
ch.Text = "Column Name";
MaLV.Columns.Add (ch);
MaLV.Items.Add(new ListViewItem("Travaux"));
MaLV.Items.Add(new ListViewItem("Stocks"));
MaLV.Items.Add(new ListViewItem("Energie"));
MaLV.Items.Add(new ListViewItem("Synchronisation"));
MaLV.Items.Add(new ListViewItem("Informations"));
MaLV.Items.Add(new ListViewItem("Quitter"));
this.Controls.Add (MaLV);
}

Hi,
i tried what u wrote to me but still not showing anything.I read in some tuto to set the View property of my ListView to LargeIcon and then set the LargeImageList property with my required images.I don't understand this.can u explain to me?
thanks
|
|
|
|

The code I posted works for me. I haven't set the image index because the list view mode is "detail". You'll need to post your code if you'd like me to take a look at it.

Just a reminder to put your code in the code block tags. It makes it much easier for others to read and review.

Does this have anything to do with C#?
It's time for a new signature.

Me, I'm dishonest. And a dishonest man you can always trust to be dishonest.
Honestly. It's the honest ones you want to watch out for...

I created a UserControl that contains three RichTextBox controls. I added a PrintDocument property, and the methods required to print (Print, PrintPage, BeginPrint, etc).
I have a loop that iterates the data and loads three strings in the RichTextBox controls, one to each control, and then calls PrintDocument.Print(). It should then print that page and get the next three strings of data to print.
This works fine for the first page, but the other pages don't print. After calling PrintDocument.Print() the program returns to the main form that called the UserControl print method.
How do I continue iterating through my loop to print more pages?

Hi,
the general answer is: in the PrintPage handler, you should set PrintPageEventArgs.HasMorePages; however it might be more complex than that when printing list-oriented controls (including RichTextBox) as there may be more data in them than is visible at any one time on your Form.

Luc Pattyn wrote: you should set PrintPageEventArgs.HasMorePages;
I already thought of that. I also thought of setting the printrange to currentpage and then repeatedly call Print. Even that failed.
pagesLeft = this.Print( e );
if ( pagesLeft < cardsToPrint.Count )
{
e.HasMorePages = true;
}
else
e.HasMorePages = false;
The Print() method calls Graphics.DrawString() and draws the strings on the PrintDocument graphics rect. For a single page it works perfectly.

This is what I suggest as a test: keep things as simple as possible. Hence use a boolean class member:
bool firstPage=true;
then do:
e.HasMorePages=firstPage;
firstPage=false;
That should print two pages, no matter what. Then take it from there.

I'll give it a try. Thanks!

I'm new to sql and would appreciate some help on the best way to structure the following type of operation. I have a db containing stock symbols. I'm retrieving each symbol, calculating a series of moving averages and updating the symbol table with the calculated values for each row in the symbol table. The way I have things structured below takes "for ever" to run through? Utlimately there will be a 1000 or more symbols in the db. Any help would be appreciated!
try
{
SQLiteConnection conn = new SQLiteConnection(Constants.ConnectionString);
if (conn.State == ConnectionState.Closed)
conn.Open();
string CommandText = "SELECT symbol FROM master;";
SQLiteDataAdapter dataAdapter = new SQLiteDataAdapter(CommandText, conn);
DataTable dt = new DataTable();
dataAdapter.Fill(dt);
DataTable symdt = new DataTable();
IMovingAverage ma20 = new SimpleMovingAverage(20);
IMovingAverage ma50 = new SimpleMovingAverage(50);
IMovingAverage ma200 = new SimpleMovingAverage(200);
foreach (DataRow r in dt.Rows)
{
CommandText = "SELECT * FROM " + r["Symbol"].ToString() + ";";
SQLiteDataAdapter symdataAdapter = new SQLiteDataAdapter(CommandText, conn);
symdataAdapter.Fill(symdt);
int count = 0;
foreach (DataRow symr in symdt.Rows)
{
if (symdt.Rows.Count >= 20)
{
ma20.AddSample(Convert.ToSingle(symdt.Rows[count]["Close"]));
symdt.Rows[count]["MA20"] = ma20.Average;
}
if (symdt.Rows.Count >= 50)
{
ma50.AddSample(Convert.ToSingle(symdt.Rows[count]["Close"]));
symdt.Rows[count]["MA50"] = ma50.Average;
}
if (symdt.Rows.Count >= 200)
{
ma200.AddSample(Convert.ToSingle(symdt.Rows[count]["Close"]));
symdt.Rows[count]["MA200"] = ma200.Average;
}
++count;
}
SQLiteCommandBuilder mySqlCommandBuilder = new SQLiteCommandBuilder(symdataAdapter);
symdataAdapter.Update(symdt);
symdt.Clear();
symdataAdapter.Dispose();
ma20.ClearSamples();
ma200.ClearSamples();
ma50.ClearSamples();
}
dt.Clear();
dataAdapter.Dispose();
conn.Close();
conn.Dispose();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
