I think that all makes sense. I was wondering how to do a check if the user used a value or not.
It kinda works now.
If I say put 3 spaces at 120", it now puts all of the items at 360". Instead of 1 at 120" 1 at 240" and 1 at 360".
I greatly appreciate your help!

| Post teh code you are using - I'd guess it's a typo, or you are using the values after the loop - when they are allready added together... If Barbie is so popular, why do you have to buy her friends?

After looking at it again I was ending my foreach statement to early.
I don't know why I didn't put the rest of the code in there.
Now it works great! I thank you for all of your help..

OK, rules for good code:
1) Don't use "#region" to break up your code, use it to group together similar items - consturctors, event handlers, public methods, private methods, and so on. If you want to show where you are handling comething, then extract it into a method, and give the method a sensible name "SingleC" and "DoubleC" for example. You can then comment these using "///" and intellisense will pick up and help you out. It makes the flow of control easier to spot. VS can extract code as a method, just highlight it and right click - "Refactor", "Extract Method"
2) Use indenting properly! VS indents things really nicely, and make it so much more obvious what it going on - I had to faff around a bit to get it like this (since I don't have and dont want) your class definitions but then VS indented everything really nicely.
3) Be consistant in indenting: one space, two space, back a bit - it really doesn't help you see what is going on. VS has loads of options for this: Indent braces to match content, number of character to indent, newlines, opening brace on same line, etc. Find a style you like, and stick with it. I prefer braces on new lines, indent three characters, indent braces to match content - but that is me, and there are enough arguments about that allready!
4) Don't use comments to explain what the code does - explain why the code is doing it. "This Sets If its a Single CEE or Double CEE" followed by a test saying "if (DBLCee == "False")" is useless - why is it important to know if it is single or double cee? I have no idea, and the comment does not help me at all. (P.S. I don't actually need to know, but someone who works on your code might).
double xVal = 0;
foreach (DataGridViewRow row in d_Endpost.Rows)
{
double postSpacing = 0.0;
double postSpacingMetric = 0.0;
string userEntry = (string)row.Cells["EPSpacing"].Value;
if (!string.IsNullOrEmpty(userEntry))
{
if (Double.TryParse(userEntry, out postSpacing))
{
postSpacingMetric = I2M(postSpacing);
}
else
{
MessageBox.Show("Invalid entry (" + userEntry + ") please enter the post spacing in inches and try again");
return;
}
xVal += postSpacingMetric;
Console.WriteLine(xVal);
}
string PostType = row.Cells["EndPostType"].FormattedValue.ToString();
string DBLCee = row.Cells["DBLCee"].FormattedValue.ToString();
if (DBLCee == "False")
{
SingleCee(Distance2Points, xVal, PostType);
}
else
{
DoubleCee(Distance2Points, xVal, PostType);
}
}
From this you can see a couple of things straight away:
1) All your processing code is outside the check to see if there is any data to process!
2) You have lest the Console.WriteLine in, when it serves no purpose now.
And the mthods became:

They are called methods: private is a keyword that can go before the return type to tell the compiler that it should not be visible outside the class.
If you are trying to learn C# by looking at samples, you will take forever, and will have to work very hard. You will find it easier if you try a more structured method, such as a book. Have a look here: C# Yellow Book[^] it is the book they give first year students at Hull University and it's both not a bad start and free.
Do you have a copy of Visual Studio yet? If not, then Microsoft will give you a copy of the Express edition (which handles most things, and is well up to learning the language). See Here[^] for a copy. Warning - it's quite big!
And of course - CodeProject is more than willing to help!If Barbie is so popular, why do you have to buy her friends?

Is it ok in .Net 3.5 to change a property within a foreach loop? Does it still run the risk of producing unpredictable results? Also, will the potential results be noticeable or might it cause some type of slow, inconspicuous but nonetheless catastrophic error.
For example:
foreach(Employee janitor in EmployeesWithPayIncrease)
{
janitor.Salary += 5000;
}
Thanks for any help or information you can provide.

It is fine to change a property; the only thing you can't do is change the loop variable or the list itself.
So
foreach(Employee janitor in EmployeesWithPayIncrease)
{
janitor.Salary += 5000;
}is fine, but
foreach(Employee janitor in EmployeesWithPayIncrease)
{
janitor = new Employee();
}or
foreach(Employee janitor in EmployeesWithPayIncrease)
{
EmployeesWithPayIncrease.Remove(janitor);
}are not, as it would mean it would compromise the enumeration.If Barbie is so popular, why do you have to buy her friends?

So can I! But I figure that if he is asking a basic (sensible, but basic) question like that, I didn't want to confuse him with custom comparisons, etc. I found it refreshing to be politely asked a sensible question  If Barbie is so popular, why do you have to buy her friends?

True
I can also think of ways to make the other two pieces* of code work without (changing them, of course)
But it's not like that's going to happen in the real world a lot either
edit *: well ok only the last one, unless I'm allowed to cheat

The setter of that property could be changing the collection in some way

Well that depends on what the property is doing..

You can't modify an object in a foreach loop like that. You have to loop differently (for, while, etc).45 ACP - because shooting twice is just silly

Yes you can - provided the property you modify does not alter the comparison, or add / remove items from the collection. Increasing the salary would not be a problem.  If Barbie is so popular, why do you have to buy her friends?

When a foreach is applied to a collection, C# will have the collection return an enumerator (I believe by calling a method, GetEnumerator). With the built in .Net types, those enumerators have logic in them that throw an exception if they detect that the list has been changed since the enumerator was created. They do this by taking a snaphot of the version number stored in the collection. Whenever a collection is modified, .Net increments this version number. And whenever an element is gotten from the enumerator, it checks it's version number against the collection it was created from.
The version number is only incremented for operations that change the structure of the list (reordering items, item removal, item additions, assigning items, and so on), not ones that change simple attributes of the list.
Also, most programmers are not aware that this version incrementing and checking must be done, so many custom collections will not throw an exception when the collection was modified in a foreach. For example, you could yourself create a custom collection that doesn't check if the collection was modified. Then no exception would be thrown when you modify the collection (add items, delete them, etc).
Whether or not modifying the collection during a foreach would cause an error (note that I didn't say "exception", I said "error") entirely depends on the collection.
