Declaring a single-dimension Array in a Form app.

[brreakerr]

After checking on the internet I've found out that I can't simply use static arrays like I used to in console c++ (int i[32];) but I have to use some strange commands.
Well, I've found this:

array<Int32>^ value1 = gcnew array<Int32>{0, 1, 2};

The thing is I basically want to get all the values from a database, so I mainly want to declare an array that can hold a number of values. The problem is that the array I need has to hold 92 variables, so I can't just use

array<Int32>^ iArray = gcnew array<Int32>{0, 1, 2, 4, 5, 6, 7}; // etc 

Also, I've read something about this being a dynamic array, does that mean that basically if I define it like this but then I use like:

array<Int32>^ iArray = gcnew array<Int32>{0, 1, 2};

for ( int i = 0, i < 92, i ++ ) {
       iArray[i] = i + 1;
      }

will create the array iArray which would display:
iArray[0] = 1
iArray[1] = 2
etc?

When in .Net, use collections instead of arrays. Much simpler. In your case, you can use List<int>.

[brreakerr]

After looking up the List command, I understood that I should go like this:

List<int> iList = new List<int>()

for ( int i = 0, i < 92, i ++ ) {
      iList.Add(i) = i + 1;
}

Like basically creating the list and using it like I would use a normal Array in console programming ?

I shall try this, thank you for your time and reply :)

Edit: Also, for example iList[0]; could be used as a normal int, right? Just making sure :D

Well it seems it won't let me use it, as this is what I've got:

1>c:\users\breaker\documents\visual studio 2010\projects\damagecalculator\damagecalculator\Form1.h(68): error C2143: syntax error : missing ';' before '<'
1>c:\users\breaker\documents\visual studio 2010\projects\damagecalculator\damagecalculator\Form1.h(68): error C4430: missing type specifier - int assumed. Note: C++ does not support default-int
1>c:\users\breaker\documents\visual studio 2010\projects\damagecalculator\damagecalculator\Form1.h(68): error C2238: unexpected token(s) preceding ';'

The lines are

int iLevel;
List<int> iHealth = new List<int>();

I know these may be stupid questions, but I am fairly new to this, and I appreciate any help I can get :D

After adding

using namespace System::Collections::Generic;

I got rid of those, now I got:

1>c:\users\breaker\documents\visual studio 2010\projects\damagecalculator\damagecalculator\Form1.h(68): error C3845: 'DamageCalculator::Form1::iHealth': only static data members can be initialized inside a ref class or value type

Edit: Solved that too using

static int iHealth = new List<int>();

[brreakerr]

Now I got an error telling me

c:\users\breaker\documents\visual studio 2010\projects\damagecalculator\damagecalculator\Form1.h(70): error C2750: 'System::Collections::Generic::List<T>' : cannot use 'new' on the reference type; use 'gcnew' instead
1>          with
1>          [
1>              T=int
1>          ]

So I changed it from:

static int iHealth = new List<int>();

to

static int iHealth = gcnew List<int>();

c:\users\breaker\documents\visual studio 2010\projects\damagecalculator\damagecalculator\Form1.h(70): error C2440: 'initializing' : cannot convert from 'System::Collections::Generic::List<T> ^' to 'int'
1>          with

1>          ]
1>          No user-defined-conversion operator available, or
1>          There is no context in which this conversion is possible

Edit: Sorry, doubleposted instead of editing..

You seem to be confusing C# with C++/CLI. I don't know CLI, but I know C# and your two new lines are C#. I THINK C++/CLI would be:

List<int>^ iHealth = gcnew List<int>();

Review your core tutorials on C++/CLI as you don't seem to have a good grasp on the basics of the language (me niether, but I do my .Net in C# instead).

[brreakerr]

Well it is C++/CLI as far as I know (Visual studio 2010 Express Windows Form Application)

When I tried the one you gave me, you know, List<int>^..etc

error C3845: 'DamageCalculator::Form1::iHealth': only static data members can be initialized inside a ref class or value type

Googled it, found out it should be a static, changed it to a static, the problems kept going :D

[webJose]

Cannot help further. It is a C++/CLI language issue, not a .Net issue. I know .Net with C#, so keep Googling or wait to see if someone else contributes here (unlikely, so don't hold your breath).

My best recommendation would be for you to sit down a read a good tutorial on C++/CLI, the language.

Post all of your code and what you're trying to do and I can help. Do you know the size of the array you want to begin with? do you need to use a list or an array?

[bobdabilder]

for example: this will get you an array of int size 92 populated

array<Int32>^ iHealth = gcnew array<Int32>(92);
				for(int i = 0; i<92; i++)
				{
					iHealth[i] = i+1;
				}

This was populated on the form load event.

[brreakerr]

Tried that, didn't work, got the static error.
As I had to change to double instead of int, this is how I fixed it:

static array <double>^ iHealth = gcnew array<double>(92);

Works without any problems for the moment

[bobdabilder]

are you doing this in a class? can we see the code?

	private:

etc

[bobdabilder]

are those variable meant to be global? consider where you want those to be available. I'm not sure of your ultimate goal here. hope this helps.

[bobdabilder]

go to design mode and double click your form. this will give you the code for the form load event. drop in your code there and designate your array as a type Int32. this will allow you to use the managed types. this will also shine some light on how to manage the variables you create.
