Thanks, but having read the Microsoft information I fear I may be debarred - it says that I have to have Microsoft Visual Studio .NET for developers, whereas all I have is the miserablt C# Express Edition (2005 version plus Service Pack 1, at that). Do you know if it is it worth trying with that?
Thanks again.

I've never used Express Edition. However the PIA's are just assemblies so I would guess there should be no problem.

Like led mike said, read up from Microsoft on how to work with the PIA.

Hi,
I have a windows form that contains 2 buttons - a "Next" button and a "Prev" button.
When the form loads, a user control is loaded into the form. After the user presses the "Next" button, the user control is replaced by another user control. If the user presses the "Prev" button they move back to the prevous control. The process continues like this until 5 different user controls are loaded. i.e. I have implemented Wizard like functionaility.
This all works fine.
My problem is that the "Next" and "Prev" buttons are always enabled. I would only like the "Next" button to be enabled if the user has completed working on the User Control that they are currently on.
In other words, once a user has completed the minimum requirements of the control they are in, the "Next" button should become enabled.
An example of this would be a user control with a first name field. When the user fills in this field the "Next" button should be enabled.
Is it possible for the user control to bubble up this information back to its parent form, so that the button is enabled at the proper time?
Thanks,
Kabir

Hi Kabir
You can use a public bool variable (true/false) in your UC. When user fills a valid text, your flag goes true, else false. And your form can use your flag to complete your task.
While (true) { Human.isLearnable = true; }

if you are using delegates i don´t see how you didn´t achieve that after what you already coded?! 
parent form? you meen main_form and only form right? because you load usercontrols in main_form? i don´t see where is the change

But it worked for me! 
It's my code:
using System;
using System.Text;
using Microsoft.Office.Interop.Excel;
namespace ConsoleApplication2
{
class Program
{
static void Main(string[] args)
{
WorksheetClass ws = new WorksheetClass();
ws.get_Range(ws.Cells[2, 1], ws.Cells[2, 3]).HorizontalAlignment = XlHAlign.xlHAlignCenter;
}
}
}
While (true) { Human.isLearnable = true; }

thank you pedram, it was the
using Microsoft.Office.Interop.Excel; i added as a reference but when i added from using XLHalign apears, thank you fro your help

Range rng = objSheet.getRange(col1, row1,col2 ,row2);
rng.HorizontalAlignment = Microsoft.Office.Interop.Excel.XlHAlign.xlHAlignCenter;
 enjoy it

Am I correct in thinking that the only difference is:
ref has to be preassigned but does not have to be used in the method
out must be assigned before returning but can be unassigned before calling the method
?
Are there any notable benifits of using either one?
[edit] Just discovered that if using out, the parameter is treated as if it is unassigned (even if it's already been assigned) as soon as you call the method. So it appears that ref is kind of an input and output parameter whereas out is just output.[/edit]

ref is input output on value types. For object types while it is technically the same you can accidentally change the pointer reference if you are not careful as objects are naturally passed by referenced. This was discussed on this very forum a few weeks ago.

Perhaps not in this case. In many others it is and without doubt. We see a large number of users here that make no attempt to learn software development. They seem to believe internet forums are a replacement for learning. Given the nature of text messages it is not always apparent when someone is not in that category of users.
If you are not one of those people, then you should not be offended by my comment, correct? In fact it seems you would be inclined to agree with it.

Thanks - I'll investigate further as what I did find by googling never suggested that.

Well, that's the purpose of using the ref keyword on a reference type.
Ennis Ray Lynch, Jr. wrote: as objects are naturally passed by referenced
No, they are not. You have to distinguish between passing a reference as argument and passing an argument by reference.

While you are technically correct most texts and online sources treat the value pass of a pointer to an object as a pass by value so what most people think is happening is a reference. Which is why I make the statements I did, most people do not know what actually happens behind the scenes and more often than not it creates strange bugs.

I figured this was a bit of pointer magic creating the subtle(ish) differences. I'm searching right now to find some info on what pointers are passed where and what values/pointers are changed etc in the two different scenarios. Not found much yet though.
Thanks for your clarifications.
