Not triggers actually.You have "sp_add_alert" like http://msdn2.microsoft.com/en-us/library/aa259587(SQL.80).aspx
by this you can create a database alert .I just wana know how to notify the alert to the application.

How can I get the DVD name?

Hello,

I am currently using C# and DirectShow to create a DVD Playback. I am using DirectShow DVD Navigator/Splitter Filter to read the DVD stream directly from a DVD disc and produces individual media type outputs, such as audio, video, and subpicture.

I was wondering if there is way to get the name of the DVD and from this filter and display it on the User Interface? After all, once the DVD is placed on the DVD-Driver, the name of the movie appears on the driver.

Thank you for your help and any information to get this problem solved

XP-style folder tree?

I spent a several lifetimes by searching how to implement nice folder tree in C#. A tree which looks like that in Windows Explorer.

There are several solutions that are complicated, platform-dependent and full of errors. What I need is to implement a tree usable on different platforms only with minimum modifications (it will show "Desktop" and "Network Places" on Win32, but can be simply modified to work well on Linux or Mac with Mono).

Of course, there is FolderBrowserDialog but this is a dialog and I need a control that can be docked inside a form and throws several events (directory changed etc.)

Any help would be appreciated.

Document and Application icons

Hi All,

You can set an application icon in the "Application" page of the project properties in visual studio. This works.

I can use the same icon for my filetype, assigned through the following registry key and value:-
HKEY_CLASSES_ROOT\MyFile\DefaultIcon\[default value] = c:\mypath\myexe.exe,0

Which uses the 0th icon in my app for the file type icon. But how can I add another icon embedded to the exe to use instead? Back in the VC6 / c++ days this was easy. the icons would of course end up being c:\mypath\myexe.exe,1

Many windows binary images have multiple icons in. How to implement this in c#?

Thanks

Jon

You can't mix languages. You can write a dll in managed C++, which uses these files, and uses a managed class to expose their methods to C#.

Hi,

i didn't test this but found it by searching for the local PC name.

System.Net.Dns.BeginResolve
or
System.Net.Dns.Resolve

if you also write the server app. you can send it yourself by using this at server site.

System.Windows.Forms.SystemInformation.ComputerName;
or
System.Net.Dns.GetHostName();

hope it helps. Smile | :)

Okay i did a small test for you .. and seems to work (but depreceated).

System.Net.IPHostEntry tmp = System.Net.Dns.Resolve(textBox1.Text);
textBox2.Text = tmp.HostName;

fill in IP address in textbox1..

I think you should use
System.Net.Dns.GetHostByAddress(String address)

Yep. Also seems to work.

VS2005 suggests System.Net.Dns.GetHostEntry() when compiling.

so there are several ways... Wink | ;)

Casting object

I was trying to "upper" cast a class. I looked like this but I get a Exception. Is there anyway to have a extended class and cast to it?

public class FirstClass {

}

public class SecondClass : FirstClass {

}

public class Main {

  public Main() 
  {
    FirstClass iFirstC = new FirstClass();
    SecondClass iSecondC = (SecondClass)iFirstC;
  }
}

I get a error on the line.

SecondClass iSecondC = (SecondClass)iFirstC;

Re: Casting object

While syntactically correct, executing that statement will throw an exception, since an instance of iFirstC is not of type SecondClass. If you prefer not to handle exceptions, you should use the as operator and check for null.

SecondClass iSecondC = iFirstC as SecondClass;
if (iSecondC == null) {
    // Handle error
}

You can only cast SecondClass to FirstClass, but not FirstClass to SecondClass.
FirstClass is parent, SecondClass is child.

Only if the object is of the "extended class" (aka derived class).

The following will work:

FirstClass iFirstC = new SecondClass();
SecondClass iSecondC = (SecondClass)iFirstC;

This is because the actual object is a SecondClass even although it is initially referenced as a FirstClass.

Does this help?

Image file validation

Hey.

I was wondering if any one can point me towards some resources that outline/explain the dangers associated with allowing users to upload image files to a web server.

I shall be using the MIME type as one step of validation and maybe limit uploads to jpeg so i can read the file header and associated data as validation (not fool proof i know).

Any advice on validation and the dangers will be much appreciated.

Cheers

Making form full screen in windows mobile ce 5.0 c# application

I am writing a Windows Mobile CE 5.0 c# application, and I want my form to be completely full screen, and not movable. I have been able to make the form unmovable and maximized. However, want it to cover the task bar as well on the PDA device (it's a symbol one).

I have done some PInvoke calls to hide the task bar. But still, when setting the form WindowState property to Maximized, it does not take up the blank space left by the task bar. Any help please?
