To explicitly raise an event in C# you just call the event as it were a method. You first must check to see if it is null. If it were null then there are no registered methods to that event and an exception will be thrown.
if(Clicked != null)
Clicked();
Your deal with the tab page control is more difficult. If I understood you correctly you want to fire an event of a control from the outside. You will have to send it the ?WM_MOUSECLICK? event, to do that you will need to inject that event into the message queue of Windows itself. You will need to use the native Windows API to do that. There may be other ways, but I am currently unaware of them.

I have to change some of my logic based on the error returned by a code. I have to first try to do a simple insert in a table. If it throws a error then i will have to change the statement(update) and again try the insert. How can i do this. Sorry if i hv posted the question in the wrong discussion board. It may be a quesiton of c# also

I assume that you expect an error because the record already exists? Then do it the other way arond; first try the update and check how many records were updated. If the record didn't exist the number of records is zero, and you know that you have to make an insert instead.
If you are using MS SQL Server, you can do this in a stored procedure:
create procedure DoSomeSetting
@SomeId int,
@SomeValue somedatatype
as
update DaTable
set Something = @SomeValue
where SomeId = @SomeId
if @@rowcount = 0 begin
insert into DaTable (Something)
values (@SomeValue)
end

For nextLine = _CurrentPrintGridLine To Min((_CurrentPrintGridLine + RowsPerPage(_PrintFont,
e.Graphics)), CType(_DataGrid.DataSource, System.Data.DataTable).DefaultView.Count)

IIS is installed in your PC or not. I think ,System.Net.Mail.SmtpClient.Send user virtual SMTP if you not specify Explicitly .
Check Virtual SMTP under IIS is running or not.If not then run Virtual SMTP.
Then you can send mail successfully.

set enable drag to true
create a variable in form class
bool draging
on mouse down event do
draging = true
on mouse up event do
draging = false
on mouse move event do
if(draging )
get mouse position every time save it to point vriable
check current postion with previous one
if they are not equal
change
this.position.x-=(point.x-e.mouseposition.x);
this.position.y-=(point.y-e.mouseposition.y);
and you are done
the above name of properties meathod may vary from actuals

I can't seem to figure out a way to loop over all cells in a DataGridViewColumn from within the column itself.
I have a class which extends the DataGridViewColumn class, and from within it I need to check all cell values in a way similar to:
foreach(DataGridViewCell cell in this.Cells){
// evaluate cell contents
}
Is there any property of the column I can use to achieve this? This functionality seems to be lacking from the column classes, though implemented in the row classes.

Can anyone tell me where I can download OpenSource application that has been developed with modules?
Or a book to download with that topic - how to develop module oriented applications?
Thanks.

Just break your app into DLLs, surely ?
Christian Graus - Microsoft MVP - C++
Metal Musings - Rex and my new metal blog

And this is it? Just break into dlls?
Then, this is something like plugins?
But, what if I want to store in Xml file which module have to be placed in panel control?
I want to have a module oriented application, but I want to enable to place a modules on forms by specifying its position in Xml file, like:
<root>
<Module Name="UsersList" Position="LeftPane" />
<Module Name="Diagram" Position="LeftPane" />
<Module Name="ManageUsers" Position="MiddlePane" />
</root>
So when program loads, he (program) decides where to place a module (in which pane) based on informations in Xml file.
I know that I have to create a new instance of UserControl and then to place it in Panel, but how can I do this in a loop when I specify the name of the module (from xml)?
In ASP.NET I will do this like so:
Control c = this.LoadControl("control path");
c.ID = "blah, blah";
PlaceHolder.Controls.Add(c);
I want the same functionalaty in Win Forms.
Thats why I've asked about OpenSource program or a book with this topic, to see how can I achieve this.
I hope you understand what I want.
Thanks.

You are trying to dynamically load assemblies and instantiate types. This[^] article should give you a start. You'll primarily be using reflection to instantiate types from strings in the XML file.

Thank you. This article will help.
So module oriented application is done like plugins or this is another way to achieve a module oriented application?

My apologies if this has been covered earlier or elsewhere - I did look but couldn't find anything.
I'm coding an app in C# using VS 2005 and I'm looking to make the interface as Vista-like as possible. Clearly, things like the control boxes on forms will be handled by the the OS - but what about buttons and the green-glow progress bar (to name a few)?
Are there libs I can download from MS to build into my app to get these "Vista effects"?
Is there something simple that I'm overlooking?
Any help is much appreciated.
Kind regards,
John.

Glowing buttons are progress bar are also handled by the OS. If your controls use XP style on XP, they should also look fine on Vista.

I am loading a form from an XML. I store the location and size info as follows:
<window number="1" x="110" y="145" width="700" height="722">
But each time I load the form, it's height is exactly 20 pixels smaller than what is in the file.
Not to mention the form I launch from shows a 20 point shrinkage as well even though visually it does not chage size.
The code I use to launch the window is:
Window win = new Window(this, name, nextCollWinXMLNode);
win.Show();
Has ayone experienced this behavior before?
Thanks,

it is dependent on the height of the title bar which in default xp theme is 20 pixels
size of title bar may variate with change in os and / or theme
toget rid of this experiment with position and size variable
i did that few weeks ago but i didnt remember what actualy was the solution
