It's a good point, but this still comes back to you not knowing what the process is because FireFox runs multiple instances under one process id (which is why Process.GetProcess(id).Kill() doesn't work).

I've just hacked together this sample application, and GetProcessById(i).Kill() worked. Both instances that I had open were closed, and one process was detected:
int i = 0;
foreach (Process p in Process.GetProcessesByName("firefox"))
Console.WriteLine(i = p.Id);
if (i != 0)
Process.GetProcessById(i).Kill();

Good sample - and it seems to have been a bug in the version I put together at first, using CloseMainWindow() at that point rather than Kill. Rather stupid of me.

Thanks for this. It works fantastic!

Can you not do what most apps do - detect if the FF process is running, and display a "Please close Firefox, and press OK to continue" dialog. Then you've just got to detect if its running, and not worry about trying to make it close. (Have you considered that killing the process might corrupt the very database you're trying to read?)

Hi
I would like to know how do I incorporate AForge.NET to my C# program for motion detection. I have installed AForge.NET but I get an error " The type or namespace name 'AForge' could not be found (are you missing a using directive or an assembly reference?)"
Thank you in advance.

This may seem like a stupid question, but have you actually included a reference to AForge in your project? Just because it's been installed on your machine doesn't mean that your project will automatically pick it up - you still need to add a reference to it.
Right click on your project and click "Add reference..." to bring up the references dialog. At this point, if AForge has been installed in the GAC, you can add a reference from the .NET assemblies tab. If it hasn't, you'll need to browse to the folders containing the DLLs and add them from there (making sure you pick up any items that AForge is dependent on).

i'm try to execute a function on button click and hold event , have anyone has got the experience on doing this,
i need to execute the function while the user is pressing and holding the button.
|
|
|
|

Try using both the mouse down and mouse up events. The first starts the function, the second stops the function (so to speak)

I'm not certain what you are trying to achieve, so is this what you want:
1) The user presses the mouse down, nothing happens immediately.
2) When the user has held the mouse button down for some time, something happens
3) The user then releases the mouse button.
If so, then the way to do it is:
In the MouseDown event, set a bool to indicate the mouse is down, and start a timer.
If you get a MouseUp event, and the bool is true, kill the timer, clear the bool.
If you get a Timer.Tick event, and the bool is true, kill the timer, and perform the action.
Note that this may not work with some controls, as they handle mouse events differently (Button, CheckBox, ComboBox, and RadioButton) - see here[^]for sequence details.

Im new to the entity framwork approach and im planning on using it for a small application here at the office.
However , i can see EF to become a very good approach in some other applications we are planning on writing in the near future.
A bought a book called "Programming entity framework" from Oreilly , but it has so many errors in it so i cant really do the examples and get a clear understanding on how to accomplish the following.
I need to write a class library to handle all the database calls and then return the results. I just want to send the LINQ statement to the class , and then get the result back.
I have tried to find examples on the net , but i dont find anything that i could look at as an example.
Can anyone please send me links or give me an example on how to handle this for Inserts , updates and deletes.

Try Googling on linq to ef crud. I got loads of hits and the top few looked as if they concerned the type of functionality you are looking for.

Ok so im making a program thats made up of lots of custom user controls. Basically like plugins. Now it works great with all my "plugins" by dragging them onto the form, but what I want is that the user can add the dll's of the controls he wants and my program dynamically loads them in(and I will size and place them etc in the code).
Im sure this is possible as tons of apps do it. So what is the best way?

Is this a winform or an Web page

Sorry, its a winform. Would be useful if it would work when I ran it on linux with mono(just to be future proof).

You first need a method of loading an assembly from a path. You can use Assembly.LoadFrom for that. Then you can call GetTypes on the result from that; you'll get a collection of Types from that. Iterate through each of those, and check to see if it inherits from Control. If it does, call Activator.CreateInstance and cast it to a Control instance. Then you just have to add it to a form and do your sizing

Sounds good, thanks alot

Cool got it working. Thanks alot!
By the way for anyone reading this heres the code I used excluding the obvious positioning and fluff:
<pre>
Assembly asm = Assembly.LoadFrom(dlldirectory);
Type typ = asm.GetType("My_Control.UserControl1");
UserControl uc = (UserControl)Activator.CreateInstance(typ);
this.Controls.Add(uc);
</pre>

Hi,
I have a method which is in another project (but in the same solution), I create a delegate to that method and then use delegate.BeginInvoke to Asynchronously call that method and the callback method is in the calling project. Now the problem is when the invoked method completes, I need to somehow signal the callback method if the invoked method has succedded True or False, and because the invoked method is in another project and the calling method is also in another project and this project has a reference to the invoked method project if I try to set some variable in the calling project from invoked method project I can't because i don't have a reference to this project and if I try to reference the project i get a circular dependency error.. which is resonable...
This is the code:
private delegate void edi2xml_delegate(object ar);
private edi2xml_delegate edi2xml_del;
public void convert_file(object async)
{
DemoApplication.edi_test edi2xml_converter = new DemoApplication.edi_test();
edi2xml_converter.file_path = pub.def.edi_file_directory + "\\" + file_list.file_name;
edi2xml_del = new edi2xml_delegate(edi2xml_converter.convert);
edi2xml_del.BeginInvoke(null, import_xml2db, (string)(pub.def.edi_file_directory + "\\" + file_list.file_name + ".xml"));
}
private void import_xml2db(IAsyncResult ar)
{
string full_path = (string)ar.AsyncState;
edi2xml_del.EndInvoke(ar);
}
public void edi2xml()
{
}
Any help or suggestions greatly appreciated.

Hi,
I suggest you have a look at BeginInvoke, EndInvoke and IAsyncResult. This trio normally manages to synchronize with and obtain return values from asynchronous operations.

Hi to all,
I have a problem regarding form resizing. I am devloping a window application using C#.NET. I am using an MDI Form to open other Forms. I have set padding property of that MDI Form.
The problem I have is, whenever I am Changing the screen resolution My form does not resize.
Please help me to solve my problem. How can I resize my window Form dynamically as per the screen resolution changes or is there any solution so that eventhough the screen resolution changes My form design should not change
--
Thanks & Regard
Sanket Patil.

Catch the Microsoft.Win32.SystemEvents.DisplaySettingsChanged and DisplaySettingsChanging events. When you receive the DisplaySettingsChanging event, make a note of the then-current resolution. When you receive the DisplaySettingsChanged event, get the current resolution. You now have the two needed resolutions; if they're equal, you don't need to do anything. If they aren't, then the Form's width is [PreviousWidth * (previousResolution.Width / currentResolution.Width)] and the height applies the same formula, but with heights instead of width

How do I get a form to lock focus to where the user cannot switch to the parent window without closing it first?
