Awesome! This did exactly what I was looking for. Thank you!
For anyone else that is using ComboBoxes (or similar controls, I'm sure) I also had to add:
[DesignerSerializationVisibility(DesignerSerializationVisibility.Hidden)]
new public ComboBox.ObjectCollection Items
{
get
{
return base.Items;
}
}
to get the Designer to stop adding items to my collection. Without this the constructor was adding its items, then the designer added those items again.
Thanks again!

HI All,
I need to implement chroma key features.
I need to draw a graphics on a pictures box and apply to this a chroma key at background color (es Violet) to see a playback video that is under this control.
I must see a graphics and a playback video at the same time.
Can you help me with example?
Thanks.Alex

Hi,
Is there any way to find out if a SqlConnection has an open SqlTransaction?
Basically I have an object with a method that accepts a SqlConnection as a parameter. This method is called from a number of different application. Sometimes the SqlConnection has a SqlTransaction and other times it doesn't.
So what I need to be able to do is something along the lines of
public bool Post(SqlConnection cn, int ID)
{
SqlTransaction trans;
if(cn.HasTransaction)
{
trans = cn.Transaction;
}
else
{
trans = cn.BeginTransaction();
}
return true;
}
Is there anyway to get something similar?
Thanks,
David

I rather suspect that you could just check to see if the Transaction is null or not on the command."WPF has many lovers. It's a veritable porn star!" - Josh Smith As Braveheart once said, "You can take our freedom but you'll never take our Hobnobs!" - Martin Hughes.

There is no command being passed in, just a connection.
So when I create a command object I want to do something like.
SqlTransaction trans = null;
cmd.Connection = cn;
if(cn.HasTransaction)
{
trans = cn.Transaction;
}
else
{
trans = cn.BeginTransaction();
}
cmd.Transaction = trans;

Shouldn't you track that yourself?

Ideally we would/should be.
But there are so many applications using this class at the moment that it's not really feasible to revisit them all right now.

I'm looking to add webcam support to a web page but i really have no idea where to start. I can use any version of VS so thats not a problem. I've seen a few examples on here about how to do it but they were all over the place. Any ideas on where to start? I'm obviously not ask for code to do it but whats the easiest way to get it done would be helpful. Thank you in advance.

Hi...
If you have seen the Gmail webcam support from browser while chatting, the same can be implemented.
To enable webcam support Gmail asks to download an activeX at first. So you also can create and API in C# which will capture the image from the webcam and ask the user to download it when he/she wants to have webcam support.
You API will search for the webcam on various ports of the users computer and streams images from webcam to your server and also display it to the user in a window.
I hope this approach will give some idea and lead to your goal.
Thanks and regards,

Hi. I've recently had to do this as well. I used the following:
browserFacebook.Navigate(@"http://www.facebook.com/login.php?api_key=" + FacebookAPIKey + @"&connect_display=popup&v=1.0&
next=http://www.facebook.com/connect/login_success.html&cancel_url=http://www.facebook.com/connect/login_failure.html&
fbconnect=true&return_session=true&session_key_only=true&req_perms=read_stream,publish_stream,offline_access");
You can intercept this URL once its done loading (string s = browserFacebook.Url.ToString()) which will show you the session key thats been returned

Any help will be greatly appreciated....

Instead of trying to remove the line, I'd try to find out why it's there to begin with. There might be an issue with your code..45 ACP - because shooting twice is just silly

No it's not. There's a common misconception that .NET 3.5 won't be able to run .NET 2 things and that's just plain wrong. .NET 3.5 is built as a set of extensions to .NET 2, so things that run on .NET 2 will run on .NET 3.5. Trust me, I document my projects with Sandcastle.

i am currently working with ptz cameras. i want to send the ptz commands thorugh http. can anybody help me?
or some good reference which could help me ?
|

| I suppose you want to send http requests to those cams and receive whatever response the cams send back. In this case you might take a look at the System.Net.WebClient class in the MSDN. With this class you can send HttpRequests and receive the responses. Good Luck. A while ago he asked me what he should have printed on my business cards. I said 'Wizard'.
I read books which nobody else understand. Then I do something which nobody understands. After that the computer does something which nobody understands. When asked, I say things about the results which nobody understand. But everybody expects miracles from me on a regular basis. Looks to me like the classical definition of a wizard.

Hi everyone.
This is a trivial question, but I can't find the answer anywhere (even though it's been asked before in these forums, but it wasn't solved in a way that satisfies me): is it possible to catch several hierarchically unrelated exceptions in the same catch block? By hierarchically unrelated I mean one isn't a subclass of the other, etc.
Basically, I'd like to do this:
try {
} catch (ExceptionType1, ExceptionType2) {
}
Is it possible, or do I need to do it as follows?
try {
} catch (ExceptionType1) {
handleMyException();
} catch (ExceptionType2) {
handleMyException();
}
public void handleMyException() {
}
I know Java allows the first format (ExceptionType1, ExceptionType2), but C# doesn't seem to like it. However, having to create a method each time this happens doesn't seem to promote code-cleanliness.
So... is it possible to do it as in Java?
Thanks!modified on Wednesday, March 10, 2010 6:10 AM

You have to use the 2nd method you posted..45 ACP - because shooting twice is just silly
