AFAIK the C# Compiler options haven't changed from version 1.1 to 2.0 of .NET framework. You get the compiler for free by downloading .NET framework SDK from Microsoft site. If you want to have a free IDE for Framework 1.0 and 1.1 try
Sharp Develop.

struct Test
{
int iCount;
}
static void main ()
{
Test T1;
Add objAdd=new Add(ref T1);
MessageBox.Show(Convert.ToString(T1.iCount));
}
class Add : Form
{
Test t;
public Add(ref t1)
{
t=t1;
}
public btnNext_Click(object sender,EventArgs e)
{
t.iCount++
}
}
In the main function, a structure of type Test is created . I am passing this as a ref to a Form class Add.
The form class has a button, a click on which will increment the iCount of the structure by 1.
When the form closes, control returns to main() , where the iCount is to be displayed.
The problem is this, in Class Add I need to store the reference of the structure for future use. But this is not happening, in the constructor of Add, the reference t1 is being assigned to t. But, the declaration of t in the class initializes a new instance of the structure and therefore any changes to the structure is not getting reflected in the structure T1, when control return to main().
What can be done here? I cannot change the design of the application.
Help would be deeply appreciated.

You have to make Test a class, or wrap it in a class before passing it to the Add function. Something like
struct Test
{
int iCount;
}
class TestWrapper
{
public Test test;
public TestWrapper(Test test) { this.test = test;}
}
class Add : Form
{
public Add(TestWrapper t)
{
t.test.iCount = 2;
}
}
static void Main()
{
TestWrapper w = new TestWrapper(new Test());
Add a = new Add(w);
Console.WriteLine(w.test.iCount);
}

You can't. None of the Managed Code languages support exporting methods in a way that would allow you do this. You have to go through the COM reference to get at a Managed Code .DLL's methods.

As you have a MVC pattern it should definitely be handled by the view. I assume every game object has a view assigned to it which controls how it is displayed. This one should also decide what image to use.

Very interesting !
Can you show us that string ?
I think, your problem is in encoding.
Best regards, Alexey.

Try running your application on another computer.
If there is no bug - reinstall your system.

Hi,
Can we have a ListBox ValueMember Collection?
If we have SelectionMode as MultiExtended, and we select more than one values in the listbox, then can we show its respective value member as we can show the SelectedIndices (Collection of selected index)
If there is a way could you please post an example with it..
And if there is not then What are the alternatives (without using and temp array to kepp track of it..some memory mgmt is required here)
Thanks a lot

try out following codes
for(int i=0;i < listBox1.Items.Count;i++)
{
if(listBox1.GetSelected(i))
{
MessageBox.Show("",listBox1.GetItemText(listBox1.Items[i]));
}
}

This would work absolutely fine, but you did not get my problem
I am displaying some value in the listbox and actually require some different value, say for e.g. i am showing names in the box whereas if the user selects a name i am retriving the corresponding employee ID for that name. Now this scenario is possible through ValueMember and DisplayMember property of ListBox.
DisplayMember = name
ValueMember = empId
Now the code which you gave me works fine if i need to retrive the DisplayMembers from listbox..
My question though,here was i needed the ValueMembers to corresponding selection
Thanks a lot

Hi,
when I load an image using this
Bitmap bitmap = (Bitmap)Image.FromFile(pic.Path),
it is not possible to delete the file afterwards, unless you exit the program. I tried to call .Dispose() on the object, but it seems like a bug in the FromFile method.
I found out a workaround
Bitmap origbmp = new Bitmap(pic.Path);<br />
Bitmap bitmap = new Bitmap(origbmp);<br />
origbmp.Dispose(); .
I keep working with the copy of the original bitmap as it's not locked anymore.
But, loading an image using Bitmap's constructor, it's impossible to load animated GIFs as it seems that Bitmap doesn't support them.
Now, how can I use animated GIFs and other image formats AND be able to delete the file afterwards?
Thx 
Stefan

Don't pat yourself on the back too hard. This has been known for at least 4 years now, and it's not exactly a bug. Though, some people would probably argue that it is.
An eaiser method would be to load the bitmap from a FileStream instead of creating two Bitmaps to get one. You can read more about it in this[^] KB article on MSDN.

When you call .Dispose() and the handle won't get free, it's a bug!

Thank you, that worked!
