Return some value under the try catch should not be a good practices.

Please Ignore this post

Well.. It depends on how you are using the following code snippets...

public class ReturnExample
{
private String normalExecution()
{
String result = "";
try
{
result = "Entered try block.";
return result;
}
catch(Exception e)
{
result = result + "Entered Catch block.";
return result;
}
finally
{
result = result + "Entered finally block.";
}
}

public static void main(String[] args)
{
ReturnExample example = new ReturnExample();

String result = example.normalExecution();
System.out.println(result);

}
}

Here you will find the reaturing value is updated;

Oh, yeah, there is that; but it's easily avoided by not writing that way. Big Grin | :-D

I suppose a better position is simply to avoid return in catch and finally blocks, but allow them in try blocks as long as there are no returns outside the try (the catch must rethrow).

In fact it may be better as an argument for the Single-Return Brigade.

First you said.

Here you will find the reaturing value is updated;

result = "Entered try block."!

So what's wrong with this?

At next I said try and finally and not try and catch.
And whats the difference between try finally or using?
Both do the same!

Now to your statement "its not a good practice".
Whats wrong with the practice to cleanup everything
you allocated in an function?

Now one question:
Ever seen the limitations of the garbage-collector?
So it can be a good practice to collect the generation
zero (objects with a short lifetime cycle) in a
finally statement, if your objects eats up a large amounts of
memory, or the gc kills your performance!

At last one word to those crying out never catch something till the
exception reaches the gui layer.
This is wrong in general. Its right that you should not catch
everything and send it to nirvana but how about this? (pseudocode)

ConnectionObject con = null;
TransActionObject trans = null;
try
{
    con = new ConnectionToSomeDatabase(...);
    trans = new TransActionObject(con, ...);
    // do something
    trans.Commit();
    trans = null;
}
catch
{
    if(trans != null)
        trans.Rollback();
    throw;
}
finally
{
    if(con != null)
        con.Close();
}

How to implement something like this?
Whats the point not to use the given possibilities?

If somebody now says, its slow, then you are right
if you use this in a very fast loop, but how about
start a transaction on a database? There is not
comparision!

So just my 2 cent on this.
And yes I will continue make intensive use of this kind of
statements!

NUnit execution from a share?

Hi all. Does anyone have any experience deploying a .nunit file to a network share?

I'm trying to share everything involved with running a particular test suite such that anyone on the team can simply access the share, open my nunit file in their NUnit-gui and run to see my status. The test suite that is to be shared is not dependent upon executing any custom code. Every one of the tests is structured similarly to this:

[TestFixture()]
public class CoverageTests
{
     [Test()]
     public void ReportStatusOfTask1()
     {
         Assert.IsTrue(false, "Task 1 has not begun yet");
     }
     [Test()]
     public void ReportStatusOfTask2()
     {
         Assert.IsTrue(true, "Task 2 is ready for review");
     }
}

Hello Dear Friends,

I've an application which shows the video from the webcam.
I want to create a C# application which can capture the part of the first application that shows the video in it. Can anybody suggest the way to do this. One way to do this is as described below

1) From the first running application that shows the video in it we can get handle of the window and from that window handle we can get the left,top, right,bottom of the area of the application that shows the video. I've HWND of the first running application but how do I get the left,top,height,width of the area which shows the video.

Is there any other way to achieve this or suggestion for this.

Thanks in Advance,

you need the handle of the control that shows the video or calculate the correct region if you know the correct location of the "videocontrol"..

Hi rootjumper,

Thanks for the response.

The problem is that it is the SKYPE which shows the video while we do the video call.And I don't think it use any control for the video so how to get the handle of the region or the location of the video region?

Thanks

ListView being buggy [modified]

I have a ListView control with a column(just for temp. test) and 2 Groups.

Now, the LV getting populated with 10 items(0..9) and associated with first group in ListView. Now when all done, I'm iterating the Items collection. And found it same as appearing in ListView.

http://img40.imageshack.us/i/40225142.png/[^]

private void Form1_Load(object sender, EventArgs e)
{
    for (int a = 0; a < 10; a++)
    {
        ListViewItem lvi = new ListViewItem(a.ToString());
        listView1.Items.Add(lvi);
        listView1.Groups[0].Items.Add(lvi);
    }
}

private void button1_Click(object sender, EventArgs e)
{
    richTextBox1.Clear();
    for (int a = 0; a < listView1.Items.Count; a++)
    {
        richTextBox1.Text += listView1.Items[a].Text + "\r\n";
    }
}

now, When I set its sort to Descending...it appears like this

http://img39.imageshack.us/i/43854370.png/[^]

In the above screenshot, the indexes are accurate but its showing '9' at the end.

So I thought to add/insert items manually without using inbuilt sorting. And I did but problem persists. Its showing in the sequence the items added/inserted. However the indexes are correct. Any idea guys ?

I also tried ListView.RedrawItems() but nothing seems to works.

Edit : Found something...but View is already set to Details

C# WebBrowser control setting folder views window blank until right-click [modified]

Good morning.

I was wondering if anyone has come across this anomoly.

I have code to populate a WebBrowser control based on the folder address (e.g. C:\). This code works well and is as follows:

private void cboFolder_SelectedIndexChanged(object sender, EventArgs e)
        {
           if (cboFolder.SelectedIndex != -1)
            {
                Cursor.Current = Cursors.WaitCursor;
                SetProgressBarMarquee();
                lblLoading.Visible = true;
                progressBar1.Visible = true;
                Application.DoEvents(); 
                this.viewToolStripMenuItem.Enabled = true;
                cboSP_Site.SelectedIndex = -1;
                cboWS.SelectedIndex = -1;
                txtAddress.Text = cboFolder.SelectedValue.ToString();
                WebBrowser1.Url = new Uri(cboFolder.SelectedValue.ToString());
            }
        }

private void WebBrowser1_Navigated(object sender, WebBrowserNavigatedEventArgs e)
        {
            SetProgressBarContinuous();
            lblLoading.Visible = false;
            progressBar1.Visible = false;
            Cursor.Current = Cursors.Default;
        }

I used some code to set up the different folder views from the view menu. Everything seems to work well, but when I try to switch to details, the web browser window go blank until I right click and then it appears. Also periodically, the folder icons will not show up.

Any suggestions? Thank you, WHEELS
