I think he's talking about the driver.

You need to install the drivers that came with the USB Bluetooth Dongle. If it didn't come with any, go to the manufacturer's web site and download them from there.

Sometimes, Windows will install drivers automatically for you but they never seem to work sucessfully so I wouldn't rely on those.

The thing is:

the program is completely right,

it's function is to search for bluetooth enabled devices (e.g mobiles)
but where it is supposed to perform the search operation it finds no devices , (returns null)

after I had searched about that , I read some where that the problem might be because of:
that the program can not see the Bluetooth deriver on the computer and I may have to uninstall the deriver of the USB Bluetooth Dongle(that comes with)
so the Windows install it automatically , in order that my program can see it(use the USB Bluetooth Dongle

I had did, I uninstalled the deriver that came with , and let the windows to install it and I got the same result ,

what do you think I can do so I make my program to run successfully

note : the same result even when I installed the deriver that came with USB Bluetooth Dongle.

Thanks

hello,
i'm trying to bind the combobox in context menu, but there is nothing when open it

code:

comboBoxItem1.ComboBox.DataSource = null;
comboBoxItem1.Items.Clear();
comboBoxItem1.DropDownWidth = 100;
ArrayList MYAL = new ArrayList();
for (int a = 0; a < 2; a++)
    MYAL.Add(new Items(a.ToString(), a));
comboBoxItem1.ComboBox.DataSource = MYAL;
comboBoxItem1.ComboBox.DisplayMember = "Name";
comboBoxItem1.ComboBox.ValueMember = "Value";
comboBoxItem1.ComboBox.SelectedIndex = -1;

this code is working on a non-contextmenu combobox

any idea?

Where do you call this code ? I'd call it just before the menu is shown. There's an event for that.

i put them in Opening Event but problem persist.
i dont think it should be work if i put code just before showing as context menu added combobox, combobox is separate item.
and it can show items which are added in design time or runtime
but if we bind it then its not showing

Cool - not sure how you're showing yours, but I did this:

private void OnMouseClick(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
toolStripComboBox1.Items.Add("baban");
toolStripComboBox1.Items.Add("naban");
contextMenuStrip1.Show( e.X + this.Left, e.Y + this.Top);
}
}

and every time it showed, it had two more items in the combo box.

ohhh, thats not what i said, i said if i bind combobox then items not showing else its showing

direct adding items can be done from any event, and it works

The combobox I added doesn't let me set a datasource at all, best I could do was this:

if (e.Button == MouseButtons.Right)
{
string[] datasource = { "test1", "test2", "test3" };
toolStripComboBox1.Items.AddRange(datasource);
contextMenuStrip1.Show( e.X + this.Left, e.Y + this.Top);
}

The only way to close the menu via the combo is to double click on an item, so handle the double click event, and then from there grab the selected item.

I'm developing a healthclub software in that if the member of the healthclub has enddate today,i have to dispay the alert message about that member.please help me.Thanking you

Is this homework, or a rentacoder assignment ?

If you have a datagrid, and you want to show a single label with a value, then you look up the value in the correct row and column of the table that contains it, and put it in the label, using the label's text property.

What if the enddate was yesterday ?
