In the yourForm class
this.Icon = //your icon
|

 I actually want an icon for the executable file not just in the form's title bar.
Thanks for the reply!

It was under properties --> common properties --> general -->application.icon for my C# project. I simply overlooked it. Thanks for your reply!

Could someone post a few lines of code using Regex to validate data in a text box?
My requirements are to A)ensure that the text entered is a number that can be positive or negative and B)it can either have a decimal point or not have a decimal point. That's it....
Anything that could get me started learning Regex would be appreciated....
I've read several articles today but can't seem to find one to address this particular type of problem, that is-- I know how to validate "abc" but not an integer or floating point.

Expresso is the program you need to learn regex.
How about -?\d+.?\d? ? This DOES require a leading digit on the decimal place tho. Making this optional but making sure there's more than just a . and no numbers is a little more complex.

Using the Word Object in C# I have implemented the before save event. I set the cancel boolen to true but it still does not cancel the save. I am programming in office xp using word 10.0 dll. anybody have any idea what I am doing wrong?
public void myWordApp_DocumentBeforeSave(Microsoft.Office.Interop.Word.Document doc, ref bool SaveUI,ref bool Cancel)
{
if (GetProperty(doc))
{
Process[] procs = Process.GetProcessesByName("WINWORD");
IntPtr hwnd = procs[0].MainWindowHandle;
DialogResult result =
MessageBox.Show(new WindowWrapper(hwnd),"Do you
want to quit save
action?","OfficeTest",MessageBoxButtons.YesNo);
switch (result)
{
case DialogResult.Yes:
Cancel = true;
break;
default:
break;
//save it.
}
}
}
Thanks

I'm a student currently trying to learn C# for software engineering class. I've got a question about C# classes. In vb all you have is public class "class" and then end class. However, in C# you have:
public class Contact
{
public Contact()
{
}
}
What is the purpose of public Contact() within public class Contact?
Thanks!

VB must have constructors, you just may not have seen them. As your code stands, you could remove the second public Contact, as it does nothing. However, this code is called automatically when you create a new Contact, and so you can put any variable initialisation or other actions you may have to take to set up a Contact within this class.

VB have Constructor too but unlike C# where the constructor name is the class name the VB constructor name
is New So your VB class will be somthing like
Public Class Contact
' Class Constructor
Overloads Sub New( )
End Sub
End Class

You can have many constructors as well but they must all differ in their parameters. This allows you to create your Contact class differently depending on what parameters you pass it, which means only one of the constructors will be called when you instantiate (create) your Contact object. I think this is what they mean by the term "polymorphism".
public Contact()
{
}
public Contact(int publicID)
{
}
public Contact(int publicID, int securityID)
{
}

Sorry, no. Polymorphism is where you have an instance of a base class, and can define it to be any of the available derived classes.

Aha, thanks, is it overloading then?

Yes, the constructor is just another method that can be overloaded.

Well, overloading is also polymorphism, it's compile time polymorphism, as opposed to virtual functions, which offers runtime polymorphism.

I'm trying to load a sorted list from a database in Access. Would I put my loop statements in the constructor? Sorry for dumb questions, but we're learning this on our own. NO help from my professor as she doesn't know C#!
Like so?
VB
Public Class Contacts
Private contact As New contact
Public ContactList As New SortedList
Public Sub LoadFile(ByVal ds As DataSet)
Try
Dim tbl As DataTable = ds.Tables(0)
Dim row As DataRow
For Each row In tbl.Rows
contact = New Contact
With contact
C# - I know the dim and such isn't correct syntax, getting frustrated! Got to learn C# in 1 week!
private Contact myContact = new Contact();
public SortedList ContactList = new SortedList();
public Contacts()
{
Dim tbl As DataTable = ds.Tables(0)
Dim row As DataRow
For Each row In tbl.Rows
contact = New Contact
}

Here's what you need to do.
Before you continue with the problem, do the following--
Make sure you REALLY know --
If I have this--
class Boo
{
private:
int x;
int y;
}
1. How big is a Boo object? That is-- If I say "Boo b" -- how big is a Boo?
2. Were I to "instantiate" a Boo "object" where would I do that?
3. Is "class Boo" and object? (I think not....)
Hope this helps...

I have been tasked with creating a custom MenuItem. I can easily derive a class from System.Windows.Forms.MenuItem and add some methods to it. However, where I am having a problem is adding drag/drop capability. I need to be able to drag a MenuItem onto a toolbar. MenuItems do not support the DoDragDrop method which is what I would normally use. Is it possible to add DragDropEffects to a MenuItem?
Thanks,
Bill

You can fake it pretty easily. When the MenuItem catches a mouseDown, change the cursor of the MenuItem and the main application to something that looks like a cursor with a drag item. Then set your desired receiver's state to 'RECEIVING'. When the receiving control catches a mouseUp and it's in the 'RECEIVING' state, it will perform the operation just as if the MenuItem was really dragged. Now just set the cursor for the MenuItem and main application back to default.

The problem is that a MenuItem doesn't have standard MouseDown/Up/Move events. It just has a Click event whose parameter is a plain System.EventArgs not MouseEventArgs so I don't have access to the information that would be in MouseEventArgs. Without being able to detect if I have a left or right-click or if the Ctrl key is pressed I don't see how to tell the difference between a normal click on a MenuItem and the click that is to start the drag operation.
Thanks,
Bill

You must be using studio 2003. In studio 2005 the MenuItems have all the mouse events. There's a chance that you could look into having the application catch any system mouseDowns, and using the mouseEventArgs's X and Y coordinates, try to figure out if it came from your menuItem... but that sounds like a lot of hassle.
How about a seperate menu item called "Add Bla". After you click it the cursor changes as I said before, and you can click on the receiver. It's not exactly a drag so much as a 'click to place', but it's better than nothing.
