I have just found out about the BITS protocol and think it would be perfect for the project I'm working on (an application that uploads large amounts of data to a server). The problem is that there doesn't seem to exist an BITS API for C#, just for C++. Has anyone created a wrapper for C#? If not, do you think it's difficult to do?

You could make a managed C++ wrapper around the original C++ code. This shouldn't be very hard to do, but you need to know some C++ to get it done Smile | :)

which textbox is entered?

Hi,
I'm trying to use the same event for different textboxes - the only difference being the textbox name.
Is there a way to determine which textbox the mouse has entered in a MouseEnter event, and then be able to do things with it like

Graphics g = txtBox.CreateGraphics();<br />
SizeF size = g.MeasureString(txtBox.Text,fontsmal);

?
Thanks so much again!!!
Mel

Yes, the sender paarameter in the event handler is the textbox that sent the event

private void AllTextBoxes_MouseEnter(object sender, MouseEventArgs e)
{
   TextBox tb = sender as textBox;
   if(tb != null)
   {
       // A textbox raised this event
   }
}

The first argument to MouseEnter event "(object sender, EventArgs e)", sender is the control that triggered that event.

Hi,

You can try YourFormObject.BringToFront(). It will leave your form on top over all other forms of your application but you can access to another application without problems.

I hope that helps you. Big Grin | :-D

Combobox

Hi. I am a newbie in programming C#, and am having a mental block. I am programming for the pocketPC.

I have a Combobox named "Type" and have a list there. I want to show the results of the entry from the combobox into a text label.

For example,
I pick "fruit" from the combobox.
I want to display on the screen: "This food is a fruit"
If I pick "vegetable" from the combobox, it should display:
"This food is a vegetable"

Right now, I'm getting:
"This food is a 1"
"This food is a 2"

How can I make the 2 into vegetable?

This is what I have, and I have a feeling it has to do with the GetValue and/or GetOrdinal.... I just can't seem to get it to work....

TypeLabel.Text = rReader.GetValue(rReader.GetOrdinal("MovieType")).ToString();

Thanks... Sorry for such a dumb question. Sigh | :sigh:

If I haven't given you enough code, let me know. I can always add more. Laugh | :laugh:

Okay, I thought I understood what I'm doing, but it's not really working. Confused | :confused:

I added this:
this.GLabel.Text = this.TypeCombo.Text;

To the Windows Form Designer generated code.

I added this:

OnTypeCombo_SelectedIndexChanged "1" write male;

It gives me the following error:
Invalid token "1" in class, struct, or interface member declaration.

Hello!

Oh my bad...try this in windows for designer:
this.combobox1.SelectedIndexChanged += new System.EventHandler(this.combobox1_SelectedIndexChanged);

then have this code inside the EventArgs:
this.Label.Text = this.combobox1.SelectedItem.Text

hope that works Blush | :O

Well, it worked. Smile | :)

Thanks again.

I have another problem, errr, challenge now. I am using an SQL database to save the info the person chooses on one form (pedbone.cs).

Here's the code to the Combobox I've got on the "main" form (pedbone.cs):

// populate the list - gender<br />
                    m_cTypes = new ArrayList();<br />
                    m_cTypes.Add("Unknown");                      <br />
                    m_cTypes.Add("Male");<br />
                    m_cTypes.Add("Female");<br />
                    TypeCombo.DataSource = m_cTypes;

These are listed in a ListView

<br />
			SqlCeCommand sqlLoadEvents = m_cConn.CreateCommand();<br />
			sqlLoadEvents.CommandText = szSQL;<br />
			SqlCeDataReader rReader = sqlLoadEvents.ExecuteReader();<br />
		<br />
		while ( rReader.Read() )<br />
			{<br />
				 				lvItem.SubItems.Add(GetTypeFromNumber ((int)rReader.GetValue(rReader.GetOrdinal("MovieType"))));// Gender				<br />
                CollectionList.Items.Add( lvItem );<br />
			}<br />
		}

And here I got the Combobox text to show in the ListView, by using this code

private string GetTypeFromNumber(int nTypeID)<br />
    {<br />
        return (m_cTypes[nTypeID].ToString());<br />
    }

Now, when you click on the listview item, a new form opens up (AddEditMovieForm.cs) to view the file in more detail. And here's where I'm running into a bit of a bind.

public AddEditMovieForm(SqlCeConnection cConn, int nMovieID)<br />
                {<br />
                        InitializeComponent();<br />
<br />
                        m_cConn = cConn;<br />
                        m_nMovieID = nMovieID;<br />
                        m_cTypes = new ArrayList();<br />
<br />
                        if ( m_nMovieID != -1 )<br />
                        {<br />
                        SqlCeCommand sqlCommand = m_cConn.CreateCommand();<br />
                        sqlCommand.CommandText = "SELECT * FROM MOVIE_MNGR_TABLE where MovieID = "+m_nMovieID.ToString();<br />
<br />
<br />
                                SqlCeDataReader rReader = sqlCommand.ExecuteReader();<br />
                                if ( rReader.Read() )<br />
                                {<br />
<br />
        }<br />
<br />
                                        {<br />
<br />
      GenderLabel.Text = rReader.GetValue(rReader.GetOrdinal("MovieType")).ToString();// Gender<br />
<br />
                                                                                        {<br />
                                                                                }<br />
                                        }<br />
<br />
<br />
                                }<br />
                        }

Any help would be appreciated. I would like to add "male" or "female" into the GenderLabel.Text field. If I neglected to add any important code, please let me know. Smile | :)

Thanks guys,

M.

Hi,

You can use a Factory which uses two object like this :

the following objects inherite of DataObject (your main class)
- DataObjectOracle
- DataObjectSqlServer

Your main class : DataObject will be used by an object DataObjectFactory

Your new object DataObjectFactory will be used by all your objects whose need access to database. In your factory object you must declare a method which must be static and have a parameter type of string.
Parameter contains the name of your wanted object.

For more information see the following link which demonstrate by picture my thing Laugh | :laugh:
