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

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

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

************** JIT Debugging **************
To enable just-in-time (JIT) debugging, the .config file for this
application or computer (machine.config) must have the
jitDebugging value set in the system.windows.forms section.
The application must also be compiled with debugging
enabled.
For example:
<configuration>
<system.windows.forms jitDebugging="true" />
</configuration>
When JIT debugging is enabled, any unhandled exception
will be sent to the JIT debugger registered on the computer
rather than be handled by this dialog box.
the code is:
SqlConnection cn = new SqlConnection(@"Data Source='MOHAMEDEWEHISHY\SQLEXPRESS';Initial Catalog='Computer Sales System';integrated security=sspi");
try
{
SqlCommand cmd = new SqlCommand("backup_database", cn);
cmd.CommandType = CommandType.StoredProcedure;
if (System.IO.File.Exists(@"D:\SQLServerBackups\Computer Sales System.bak"))
{
System.IO.File.Delete(@"D:\SQLServerBackups\Computer Sales System.bak");
}
cn.Open();
int i = cmd.ExecuteNonQuery();
if (i < 0)
{
MessageBox.Show("Your database is backed up successfully");
}
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
MessageBox.Show("Sorry ... You can not back up your database");
}
finally
{
cn.Close();
}
so the problem is using SqlConnection with others not DML commands
i tried to use OLEDBConnection but it not gets result
So what is the solution????????
Thanks,

i have a datatable and i have to show the data of its 3rd column in gridview.hw can i do that

By binding it to the gridview. Plenty of examples are there on web. You can read through them.

Hi,
I am using a text box on the UI to query the database using the entered text.
Following is the code snippet
string refNum = (from Example in db.Orders
where Example.Reference == textBox1.Text
select Example.OrderId).First().ToString();
My question is..
How to show a friendly error message if Example.Reference is not equal to input value in textBox OR if no value is entered into the text field ?
Because am getting this error "{"Sequence contains no elements"}" when no value is entered or if any wrong value is eneterd. Can any1 tell me how to catch this error and show it as a friendly message to the user.
Thanks,
|

if (string.IsNullOrEmpty(textBox1.Text)) {
MessageBox.Show("Please enter some data.");
} else {
your code...
}
