the above post probably covers the api you need for filestream and binarywrite.

so my post is just to point out it would be easier to use

FileInfo and FileInfo.CopyTo

if your just copying the file and dont want to edit it.

  FileInfo tes = new FileInfo(StrFilePath);<br />
<br />
        if (!tes.Exists)<br />
            return;<br />
<br />
        tes.CopyTo(StrDestPath);

or some such off the top of myhead

I need to implement Tab Control to the ListView Filters. So if any one among you has a good understaning of this article or windows programming do help me out with it.

combobox problem

Hi im using a combobox which is populated with a fairly large amount of items (no databind). The problem im having is that sometimes when I expand the combobox it wont stay open as it should so I can scroll down/up through the items, instead it closes as soon as you release the mouse button. Anyone have any idea to why this is happening?

/thanks

Hello,

One possibility is that you move the mouse outside the Controls area, while the mouse button is pressed.
If you than release the button, the items are still all visible!
This is per design!

You could make a workaround like this.

private void comboBox1_MouseLeave(object sender, System.EventArgs e)
{
	if(this.comboBox1.DroppedDown)
		this.comboBox1.DroppedDown = false;
}

Or inherit your own combobox, and override OnMouseLeave.

All the best,

Martin

Hmm sorry to say, but that is not the case. The combobox opens on mouse down and closes on mouse up even though the pointer never leves the combobox control area.

YEP, I never said something else! (I hope so)

What I meant is, that you sometimes leave the area (as a mistake), and than you have this effect!

Insert 20,000 records with NHibernate

I am using NHibernate to insert into a database 20,000 records. I would like to know if a time of 15 sec is good or bad and if my method is the best. The code that inserts is this:

private void btnInsertHuge_Click(object sender, EventArgs e)
{
    ITransaction tx = null;
    ISession session = null;

    try
    {
        session = factory.OpenSession();
        tx = session.BeginTransaction();

        InsertHuge(session);

        tx.Commit();
    }
    catch (Exception ex)
    {
        tx.Rollback();
        throw ex;
    }
    finally
    {
        if (session != null)
            session.Close();
    }
}
...........................

private void InsertHuge(ISession session)
{
    for (int i = 0; i < 20000; i++)
    {
        Person person = new Person();
        person.LastName = i.ToString();
        person.FirstName = i.ToString();
        person.PhoneNb = i.ToString();

        Car car = new Car();
        car.LicenseNumber = i.ToString();
        car.Name = i.ToString();
        car.Owner = person;

        session.SaveOrUpdate(car);
    }
 }

NOTE: This is just a test. Smile | :)

As you adding a Car relation to Person, you are actually inserting 40 000 objects (i think Poke tongue | ;-P

Transaction in dotNET and SqlServer

Hi there .
During transaction is began , I inserted new data in table , until I don't call commit() or rollback() functions , another processes can not access to this table.
I mean, if i try to add a new data in a table with transaction and before closing transaction(commit or rollback) another process can't read that table; then a exception will occurred.

what is the problem?

I've loaded an xml file into a dataset. Is it possible to send the data from the dataset to a sql server table as xml.
Since i've to sort the xml data based upon a tag i'm loading it into dataset.

Or is there any way that i can load it to the sql server table so that i can sort it directly there in the table as xml data type.

Plz. can any one send suggestions/help.

Thanks Smile | :)

Hi there

I'm not exactly sure what it is you need, but take a look at this :

dataSet1.Tables[0].DefaultView.Sort

This way you can tell every single table in your dataset, for the default view, which columns to sort by.

Another way could be to create a custom view instead.... look for DataView, databound to a Dataset.

Correct Syntax for Multiple "if" Conditions

What is the correct syntax for multiple conditions in an "if" statement.

For example:

<br />
if var == 1 or var == 2<br />
{<br />
//code<br />
}

Thanks

first of all if you begin programming in some language you should read a book or two to get the basics right..

answer to your question:
if(var == 1 || var == 2){
//code
}

|| or
&& and

| bit or
& bit and

life is study!!!
