Sorry, I dont have an entire app nor an article about this.
I came up with this code snippet upon your request.
It illustrates the point that you may not have to do the Invoke stuff
for every single control: if you separate the "business logic" or the "model"
of what you are doing, from the user interface, then the number of
times you have to cross the thread boundaries can be limited.

Hi All,
I'm slowing finding my way around C#.
I have written an application that takes a directory, take each file in that directory and also each file in each subdirectory, and then trys to find any files with the same name
(Trying to clear up all my duplicate photos  )
SO I have written the code, and checked it and checked it again, it does not get caught in an infinite loop.
But when I F6 the app it comes up with a ContextSwitchDeadlock MDA issue.
So I set the project Properties to "Fully Trusted" and now the app just goes <blank screen="">
I've added a progress bar that slowly grows - This works
I also added a new text box and in the loop set the Text to the fileInfo.Name it was checking. But this does not update on the screen.
Anyone have any ideas how I can Fix the:
1. Context switch/stop the screen blanking out.
2. Fix the Text box updating as it loops through.
As always, thanks for looking and expecially thanks if you reply!
Tony

The TextBox isn't updated cause the loop you're talking about probably runs on the main UI thread and therefor no other messages (e.g. change text of textbox) are processed until it is done. They are queued in the message pump and get executed after the event handler finishes. Take a look at the Control.Refresh method that forces a visual control to redraw itself immediately.

Hi Stefen,

Hi,
Could you please help me to add status bar buttons to the ApplicationMenu in DevExpress. Example button: Word 2007 exit button in Application Menu.
Thanks,

Your best bet is to review the help/samples that came with the product. Then, if that doesn't work, have a look at the support forums on the DevExpress website.

Which are the settings in web.config file for sending the Emails thr' SMTP?
Sarika Wake

using System.Net.Mail;
...
SmtpClient smtpClient = new SmtpClient("smtp.myisp.com");
smtpClient.Send("tome@me.com",
"fromyou@you.com",
"Hello Word",
"This is the message");
Also look at the MailMessage class to add more functionality to the send.
You don't need to do anything to web.config.

Hello,
I am having few queries related to "reference" and "const" in C#.
1). How to pass a const value by reference.
i.e. in C++
Class Vehicle{};
AnotherClass
{
Vehicle vh;
void SetData(const Vehicle& );
}
How to do it in C#.
2). How to use const member function in C#.
Thanks in advance.

C# is crap. You can't do either.

What you are asking for is either very simple or not possible at all, I haven't tried which. You can try it:
const int answer = 42;
SetData(ref answer);
void SetData(ref parameter) { ... }
This will either automatically create a copy of the constant before it's passed to the method, as a constant can not be changed, or it will produce a compilation error, as you have to copy the value yourself.
What it looks like you are trying to do from the code, is to make a constant argument, which is not supported in C#.

Methods are always constant, you can never change the definition of a method at runtime.

AFAIK C++ const methods are, by definition, methods that can't change the state of the object they belongs.

or a way to create a string-indexed array of int (sort of the reverse of what most arrays are)... thanks!

Dictionary is a map. In .NET 2.0, generics means you can specify the type of the two arguments.
