Installing and using Windows Authentication in a Workgroup environment is a BAD idea. Since every machine in the workgroup, including the SQL Server maintains it's own list of user accounts and passwords AND DOES NOT TRUST ANY OTHER MACHINES ACCOUNT LIST, you are bound to have all kinds of login issues with the SQL Server. You're either going to have to use SQL Server accounts or change your entire network over to a domain setup where there is only ONE list of accounts and SQL Server uses that.

Hello,
I have an untyped parameter _target and the following code:
Type T;
List<object> olist;
IEnumerable<PropertyInfo> subProps;
olist.AddRange(resultSet.Select(result => GetO(T, subProps, result)));
prop.Info.SetValue(_target, olist.ToArray(), new object[0]);
I would have to write a lot of words, but I hope you understand what is the point after reading comments.
Before I posted this, I had came up with another idea:
Type t = ...;
dynamic olist =
typeof (List<object>).GetGenericTypeDefinition().MakeGenericType(new Type[] {t})
.GetConstructor(new Type[] {typeof(int)}).Invoke(new object[] {resultSet.Count});
IEnumerable<PropertyInfo> subProps = ...;
foreach (SparqlResult result in resultSet)
olist.Add(GetO(t, subProps, result));
prop.Info.SetValue(_target, olist.ToArray(), new object[0]);
I tried also using Convert.ChangeType but with no success.
What would be a working solution? An "anymous" cast would be good, like (type)object, but there is no such thing.
Thanks in advance,
Greetings - Jacek

I knew I'd have found an answer. I usually do. Eventually. After some time.
Array.CreateInstance was what I needed.
Type t;
List<object> olist;
IEnumerable<PropertyInfo> subProps;
olist.AddRange(...);
Array instance = Array.CreateInstance(t, olist.Count);
Array.Copy(olist.ToArray(), instance, olist.Count);
prop.Info.SetValue(_target, instance, new object[0]);
Greetings - Jacek

hey again. i solved my problem like below.i found below code in web but i didnt understand exactly what GetTabRect() does?
private void tabControl1_MouseDown(object sender, MouseEventArgs e)
{
if (e.Button == MouseButtons.Right)
{
for (int i = 0; i < this.tabControl1.TabCount; i++)
{
if (this.tabControl1.GetTabRect(i).Contains(new Point(e.X, e.Y)))
{
this.tabControl1.SelectedIndex = i;
break;
}
}
}
}
private void sekmeyiKapatToolStripMenuItem_Click(object sender, EventArgs e)
{
foreach (DetayForm item in this.MdiChildren)
{
if (item.tbpg.Equals(tabControl1.SelectedTab))
{
item.Close();
break;
}
}
}

When you don't know what something does, MDSN is the first place to look :GetTabRect method[^]
A simple Google "GetTabRect MSDN" will find it for you...
MSDN says "Returns the bounding rectangle for a specified tab in this tab control." which means it returns a Rectangle which contains the Tab part (on the tab list, has the text describing the tab).
|--------|-----------\
| My Tab | Other Tab |
|-----------------------------------|
| |
| |
| My Tab Content |
| |
| |
| |
|-----------------------------------| It would return the rectangle containing "My Tab", but not "Other Tab" or "My Tab Content"
Real men don't use instructions. They are only the manufacturers opinion on how to put the thing together.

If You Declare Any Variable in the Event or method ...
That variable will be only accessable in that event or method..
i.e. Scope of that varialble is limited to that mentod of event..
If you want to use any variable(i.e same variable ) in more than two events declare it outside of the scope of menthod.
means declare it in you class
i.e
class abs
{
declare Here variables;or assgn values
method1()
{
}
method2()
{
}
}
so that you can use same variable value in method1 and method 2
In your case databaseImage Variable(Bitmap) is declared in button2_click()
so you can only acces it within button2_click()
Declare databaseImage above all methods and use it in button1_click() as wel as Button2_click().

if (open.ShowDialog() == DialogResult.OK)
{
pictureBox1.Image = new Bitmap(open.FileName);
textBox1.Text = open.FileName.ToString();
Bitmap finalImage = new Bitmap(pictureBox1.Image, 320, 240);
pictureBox1.Image = finalImage;

Go back and reread the answer you were given. You might even want to pickup a beginners book on C# because it's apparent that you don't understand the basic concepts of "scope". If you want to use finalImage outside of the event handler, it has to be declared outside of the event handler. You then set finalImage's value (bitmap) inside the event handler.

Hi,
i'm writing a small application
and i want to control the webcam for another application that i got on the same PC.
i want to be able to start playing the video, and to stop playing it.
can anyone assist me?
Thanks,
Zvi

You can't. First, the device is only available for a single application at a time. Second, any settings your app lays down will be overwritten by the application that is really using the camera. You also cannot control when the other application sets these settings, so it'll quite possibly overwrite whatever you set. The normal operation is to setup the cameras settings right after opening the camera and before starting the cameras video feed. Once the camera is opened, your application cannot get at it to make changes.

well,
what i'm realy doing is writing an application for controling a Lync client.
I am using the Lync client SDK,
i was able to do all the actions that i wanted, except turning the camera on and off.
So i wondered if there is any way to do it from my application when i have the device ID.
Thanks

This[^] or this[^] might help.
The funniest thing about this particular signature is that by the time you realise it doesn't say anything it's too late to stop reading it.
