Yep. Me too. That's why I'm slowly navigating back to MC++ for most of my development. I have done some cool C# stuff - even won a Money Magazine technical award a couple of months ago for a C# system I designed and wrote for VeriSign - but for my personal work, I choose MFC/MC++.

Doesn't the compiler take care of it?

Exactly.

How do you mean? It's still a jump with the extra prolog and epilogue instructions to take care of the stack.

Yes, but since foo(a) always calls foo(a,b,c), the compiler can simply inline every call to foo(a). When you call foo (a), it can push additional two parameters on stack and call foo (a,b,c) directly.

I have a XML file like this:
- <Quiz Id="1" Date="24.07.2003">
- <Question Text="Question Text 1" Choice="a">
<Answer>text a1</Answer>
<Answer>text b2</Answer>
<Answer>text c3</Answer>

</Question>
- <Question Text="Question Text 2" Choice="b">
<Answer>text a1</Answer>
<Answer>text b2</Answer>
<Answer>text c3</Answer>
<Answer>text d4</Answer>
</Question>
</Quiz>
I want to serialize and deserialize it into a class and from that class. So my class have should have some XmlElements and XmlAttribute, But I don't know what my class should look like?
I should have XmlElement name Question, but how can I define that some attributes are for Quiz node and some for Question,and don't know about Answer node too.Because It could be for item or 3 or...
Another question is that maybe I have 3 or 4 or only 1 Question node in my XML file so how should I deal with it in my class? When I serialize it what should I concern?
Any comment is appreciated.

declare the class something like
[ XmlRootAttribute( ElementName = "classname" ) ]
public class classname
and look up the class XmlSerializer
it would probably be best to store the answer in an array.

It is possible to put a tooltip on a GDI+ figure? (on mouseOver)
The tooltip1.SetToolTip() method takes in a System.WindowsForms.Control, but there is no overload for a GDI drawing ?
|
|
|
|
|
1). Declare global variables ToolTip tt; and bool installed = true;
2). Initialize tt in constructor of the form: tt = new ToolTip()
3). Override OnMouseMove:
protected override void OnMouseMove(System.Windows.Forms.MouseEventArgs e)
{
if (bounds.Contains(e.X, e.Y))
{
this.Cursor = Cursors.Hand;
if (installed)
{
tt.SetToolTip(this, "Hello, r9 :o)");
installed = false;
}
}
else
{
this.Cursor = Cursors.Default;
if (!installed)
{
tt.RemoveAll();
installed = true;
}
}
base.OnMouseEnter(e);
}

You are genius
With all your help, I am getting better and better at understanding GDI+.
Thanks

Do you code a control or you just draw shape on the form?
All code examples supposed to work for the shape drawn on the form.
If you want to use examples to code a control, you should make some changes (some lines are not necessary and some things should be coded in other way).

Is there any way to create supplemental image encoders/decoders for GDI+? I'm assuming there must be, but I really haven't seen anything on this, not even on MSDN.

Back in the COM days when I compiled a com dll it would automatically be registered. I could then go and add it as a reference in another project by choosing it from reference window.
I just created and complied a C# Class Library component. When I open another solution and try to add that component it does not appear in the .NET list (or anywhere). I have to browse to the component's directory and select that dll.
How do I get that library to appear in the .NET section of the Add reference window?
Thanks.

To add it to the .NET section of the Add Reference, you have to add it to the Global Assembly Cache after signing it with a strong name. But, you can always just browse for its file using the Assembly Browser tab (or whatever it's called in VS.NET).

The GAC and a strong name isn't the only solution*. You can also add the path to your library to the registry.
For example, I put all my libraries (and other's) in C:\Development\Third Party\bin\, so I added the following key to the registry:
HKCU\SOFTWARE\Microsoft\.NETFramework\AssemblyFolders\Third Party\
I then set the (Default) string value to the above path. You can use the HKLM hive instead, if you want the setting to apply to all users.
* In fact, according to the docs adding it to the GAC won't work anyway, because the Add Reference dialog is path-based and doesn't enumerate the GAC.

you can also use the probing tag name inside the config file to locate its path
you can also copy the file to the apps directory
so many choices, I wouldnt put it into the GAC so early
|
|
|
|
|

add it to the GAC and it should. The reason is because vs did the regsvr32.exe for you. It hasnt changed just the options

sorry for this pathetically preliminary question..
how do i determine if the check box in a data grid column is checked or not ? any small code snippets would be greatly appreciated..
thanks

I would give you code, but thats at work, I will try though. I had a similar problem earlier today. Hope this helps.
Do something like
if (checkbox.checked == true)
{
whatever it is you had wanted to do if it were true
}
|
|
|
|
|
Depends on where do you need to check the checkbox's value, for example, if you are trying to update a row in a datagrid in the OnUpdateCommand event handler, you would do something like this:
<br />
((CheckBox)e.Item.FindControl("SomeCheckBox")).Checked<br />
where SomeCheckBox is the ID of the CheckBox control, and e is DataGridCommandEventArgs argument of the OnUpdateCommand event handler.
Is this what you are looking for?

Hi!
I wrote a windows service in C# using the .net clases in VS.NET.
It worked fine up until now, when I receive a "Access Denied" error message when I try to install it. I`m using MSI for the installer and I`m running Windows XP SP1.
If you have any sugestions, please let me know.
Thank You!
