Tips? Yes, try less ambitious projects until you have mastered C# a bit better.

You asked this yesterday, I gave a complete answer and hung around for ages expecting that you;d want to explore it more. As others have said, and as I said before, it's obvious you know nothing about web development, so buy a book and work through it.

Hey All,
I have an app with several forms. Lets call them FormA, FormB, FormC. FormA is the starting form with many text boxes to fill in. I have a button on it that then opens up the other two (FormB,C) and populates them with data from FormA. Most of the time I will be working with FormB for here on out. What I need to know is how to show the already opened formC (not create a new instance) from formB.
using this just creates a new instance.
FormC frmC = new FormC();
frmC.show();
So i need to know how to reference FormC without creating a new instance.
Thanks,
Dylan

If formC doesn't exist yet, it cannot be referenced?
I don't understand your question..

Why don't you remove the data model from the UI? What I mean by that is create an object structure that is loosely coupled to the UI. Have a look at the Model-View-Controller pattern, I think it solves issues like this also. Possibly this isn't the answer that you're looking for, but it's probably the correct way to handle problems like this.

Sorry to go off topic here, but I googled the MVC pattern trying to find something extensive yet a little simple to get a basic grasp on it. If you have any recommendations, that would be amazing. Would be a nice article for CP as well (hint hint)

Here's a simple example, and although it's in Java it's understandable enough to grasp the concept.

I really liked JP Boodhoo's 5 part video on design patterns. He covers the MVC pattern really well.

Thanks guys, Im cracking on those videos right now

Well, I'd probably do it like this:
Use a tab control (by default, the main form has access to all of the controls/data on all of the included tab pages, so you can keep your data tightly coupled to the UI if that's what you really want).
or
Create each form on a UserControl object, and show/hide them based on what you need.

LMAO Brilliant. Even better, just put all your code inside the main() function!

I agree with him however remove the complexity by using the MVC pattern.

When you open form B and C I guess you pass data to them - if the form C data is constant then you could pass that to B at the same time...
Otherwise one way you could make this work is simply call public methods between the forms (A would be the parent of B and C)
lets say TextBox1 is on form C and you want the Text value in form B...
in form A:
FormB formB = null;
FormC formC = null;
formB = new FormB(); formB.Show(this);
formC = new FormC(); formC.Show(this);
Public string GetformCTextBox1Value()
{
return formC.GetTextBox1Value;
}
form B:
FormA parent = (FormA)this.Owner;
string formCTextBox1Value = parent.GetformCTextBox1Value();
form C:
public string GetTextBox1Value
{
get { return TextBox1.Text; }
set { TextBox1.Text = value; }
}

Hopefully this may help, its not exactly what you are trying to do but its similar
Excel.Application eApp = new Excel.Application();
Excel.Workbook wBook;
Excel.Worksheet wSheet = null;
Excel.Range rng;
object opt = Type.Missing;
wSheet = (Excel.Worksheet)wBook.Worksheets[0];
rng = wSheet.get_Range("1:1", opt);
rng.Font.Bold = true;
wSheet.UsedRange.Columns.AutoFit();

Thank you for your reply.
This works great with a static range, however, I still have the same problem.
I have the .get_Range() in a loop because it is going through a bunch of cells within the workbook.
For this, it I cant use a range like "l:l", it needs to be dynamic.
In VBA i would do something like Range(cells(i,1),cells(i,2)).Borders.blahblah.
I was attempting something similar in C# with objWkSht.Cells[i,c] (i and c being integer values) but it does not seem to be the way forward... 
I would be very greatfull if you have any other idea's?
oooo, the Jedi's will feel this one....

I'm eager to help when help is honestly needed, but...
This sounds like homework to me.
Beyond that, your requirements are too sketchy to provide any help at all. Maybe they should teach more preparatory courses so you learn how to gather, define, and present requirements before you're allowed to write any code. Who knows? You might find that your real calling in life is being a specifications writer, and you can haunt some other forum instead of trying to get us to help you with homework that a) you're too lazy to do on your own, and b) will most certainly suck in its final form.

Too true. I never thought about it before, but you're right, nearly all the homework questions have rubbish specifications/requirements.
