amazingly i can see them from main
|
|
|
|
|
Its really amazing 
cause even i couldn't see private members.
|
|
|
|
|
Weird.. I tried the code as well and I can't access any private members. For instance, the code
lst.a = null;
does not compile.
Can you show the code that allows access to these members?

Well they shouldn't be
I'd try restarting Visual Studio, maybe it glitched

What do you mean by "visible" - do you mean you can access them in code, or that you can see them with intellisense / the debugger?
If it's the latter, then you're misunderstanding what private really means

Is Main a member of the Grammar class? If so, of course it can see the private fields.

Hi,
In VB.Net in a class I can define an event as:
Public Event MyEvent
and raise it in a method as :
RaiseEvent MyEvent
and in another class that has an instance of first class I can catch the event.
How can I do this simple process in C#? We don't have RaiseEvent in C#.
Actually I want to notify another class when a method executes in the class.
Best wishes

You look at the delegate as a method call. Don't forget if nothing's hooked up to it, it'll be null. So check for that.
if(this.MyEvent != null)
this.MyEvent(MyArgs);

Hope it'll help.

Hey guys
How would I go about saving an image of a control? Lets say for instance I'm drawing something on a panel using GDI+, I need to save that drawing to JPEG. Been googling around but no joy.
Any help will be appreciated
Thanks

Control.DrawToBitmap is the general answer, some Controls (such as RTB) need a bit more effort though.

DrawToBitmap doesn't works for ActiveX controls like WebBrowser.
You would better use Graphics.CopyFromScreen but It works for active window only.

What I do in my screen grabber applet is...
Define a bitmap of the appropriate size:
System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap
(
this.pPanel.Width
,
this.pPanel.Height
) ;
Get a Graphics object for the bitmap:
using ( System.Drawing.Graphics gr = System.Drawing.Graphics.FromImage ( bitmap ) )
Copy the area of the screen that the Panel covers to the bitmap:
gr.CopyFromScreen
(
this.pPanel.PointToScreen ( new System.Drawing.Point ( 0 , 0 ) )
,
new System.Drawing.Point ( 0 , 0 )
,
this.pPanel.Size
) ;
Save the bitmap to a file (I prefer PNG):
bitmap.Save ( sw.BaseStream , System.Drawing.Imaging.ImageFormat.Png ) ;
(Details left as an exercise.)

Is that a System.Windows.Forms.Timer or System.Threading.Timer? First one runs on the main thread and second one runs on a pooled thread.
If you are using Forms.Timer, consider changing to Threading.Timer. This[^] MSDN article will help.

If I want to grab a DataRowView I use:
DataRowView arrangement = (DataRowView)BindingContext[debtorDataSet, "Debtor.FK_PaymentArrangements_Debtor"].Current;
How can I get a DataRowView for the previous position without changing the position to do so please?
|
|
|
|
|
BindingContext[debtorDataSet, "Debtor.FK_PaymentArrangements_Debtor"].Position will give the current position. Get the table from debtorDataSet and take the row at position - 1.

Hi all,
Is is possible to add the result of two anonymous LINQ queries together (when the data is gathered from two different data sources), to form a variable that one foreach loop can iterate on. For example:
var query1 = from x in dataCollection
select new
{
name = x.Name,
surname = x.Surname
};
var query2 = from x in xmlCollection
select new
{
name = x.Name,
surname = x.Surname
};
foreach (var result in .....
Many thanks in advance,
Kind regards,
