The DialogResult type will be returned and it will tell you which buttons were clicked.

In a uercontrol i have in a c# application, it requires vertical scrollbars. That part works fine..but there is an annoying and limiting part of it that i'd like to fix.
When you scroll...lets say in Internet explorer..when you click on the scrollbar, move up and down, it is always changing the visible area (virtual space) of the webpage.
In my application's user control i click down on the scrollbar, move it up and down, release on the scrollbar and then it updates the visiblearea. Note that the visible area doesn't change at all until you release.
How can i get the feature of constant updateing of a controls visible area?

Hi,
you can add a handler to the Scroll event, and have it Invalidate() the Control,
causing a repaint based on the current scroll value.
|
|

Thanks for the reply, but unfortunately that does not work. I think the scroll event is only called after the user releases the scroll bar(some eventargs values are newvalue, oldvalue).
Would i have to track the click?-
(scrolling == true)
and mouse move-
if(scrolling == true)....

Scroll event works fine for me.
There also is an alternative with ValueChanged event (works when scrolling or setting
a new value).

Ok lets figure this out...
I have a user control with these properties
autoscale = true;
autosize = false;
Scroll event handler:
void SplitinfoScroll(object sender, ScrollEventArgs e)<br />
{<br />
this.Invalidate();<br />
}
i've also tried Invalidate(this.bounds);....
what am i doing wrong?
How did you set it up?

I have used live scroll bars many times, never had any problems with them.
Did you wire the event? (not shown)
Does it fire at all?
What is this in this.Invalidate? is it the control that needs being redrawn?
Use logging or interactive debugging to debug!!

yeh i need the control to change it's displayed area / virtual space.
here is the event caller(i do fire the event):
this.Scroll += new System.Windows.Forms.ScrollEventHandler(this.SplitinfoScroll);
-am i calling the right ScrollEvent?
the scrollbar is just one that automatically appears when the control's displayed area cannot display all of it's contents.
i used a MessageBox.Show("scrolling") debugging and it did get called whenever the scrollbar moved.
the controls display area needs to be redrawn.

Maybe this is one of those rare occasions where one should use Refresh() instead of
Invalidate().

Not sure off the top of my head at the moment, but you may want to look around at the Windows API for anything that grabs the currently selected text.

well....if the email body is in a textbox ( i don't use outlook) you could probably use something like
MessageBox.Show(emailbodytxtbox.SelectedText);
also look into this area(may need to add a reference)

Please don't cross post. It's rude. Read the forum guidelines.

Sorry Paul, actually It was my mistake to post in this wrong section, later I found that ASP.NET section is there for this category so I posted there too.
But I did not understand why it should be rude ! I apologize for my ignorance but I am just curious about this rule. I thought, I can acquire more knowledge by getting more response from both sections from more replies by different experts, is not it acceptable ? Anyway, Sorry again for my ignorance.

No big deal.

Most of the people that respond in these forums respond to more than one forum, so cross posting in other forums is not really likely to change the amount of responses you may get ( other than the don't cross post responses ).

It's considered rude because it makes it difficult for people to collaborate on a solution if replies are being recorded in multiple forums. It also makes it harder for people searching the forums to find the definitive answer to a question. When posting a question, consider which forum is most appropriate. Most people who answer questions, including myself, look at posts in all the main forums. Cross posting won't help you get a better answer to your question, but it will p*** people off .

Hi,
Is there any way to disable the methods Equals and ReferenceEquals?
They always seem to appear by default if I create a struct or class.
Why do I want to get rid of them/hide them?
1. Because they anoy me in classes/structs that I don't need to use them in.
2. Because out of interest I want to know if you can.
Regards,
Mark.

No, you can't. Equals is a virtual method on System.Object, which is inherited by all types (value or reference) in .NET. ReferenceEquals is a static method, again defined in System.Object.
Your types will derive (implicitly or explicitly) from System.Object, so there's no way you can get rid of them.

You'll have to create your own custom message box like Abhijit suggested. Take a look around this site, there is an article or two how to achieve this.

Hi,
I need a suggestion in handling socket communication in my project.
i am writing a diagnostic software which will run in a laptop. The laptop will be hooked upto a ring network ( 5 computers connected together in ring topology). Where i have to communicate to all the computers connected and have to send/receive diagnostic messages to all/particular computer.
I am thinking about creating multiple client socket( in diagnostic software )for all the computers connected. Each computer will run a server socket which will listen for client connection.
In this case i suppose to create 5 client socket (since 5 computers connected) and each computer will have its server socket.
Is there anyway to simplify this ie. one server socket on laptop and one client socket on each computer. In this case a client socket can't listen for server connections right?
Please suggest a better way, i want to do in TCP not in UDP
or suggest any article which will help me understand this better.
Thanks
Srini
