You don't, if you use "using"...
using namespace System::Windows::Forms;

ListViewItem::ListViewSubItemCollection^myCollection = myRecord->SubItems;
String ^field_1 = myCollection[0]->Text;

This is a good example of how to determine if I need to include the preceding ListViewItem:: (or any other preceding datatype: . I have run into declaration problems like this before but those first two lines after the ellipsis are illustrative of the approach. I am printing that one for my notes.

I didn't state that correctly, and I modified my post above...
ListViewSubItemCollection is a subclass nested class in the ListViewItem class.
It's the same thing you'd have to do with regular C++... the compiler has to
know the class and the namespace

Hi, I'm using C++/CLI and Visual Studio 2005. I have a list view control that I would like to have the columns center justified. I can center justify all the columns except the first column. The GUI designer will not change from left to center justified and if I hard code the justification it still will not do it. Is this a subtle bug? Why won't the first column center justify?
Thanks
Buck

Here's a thought. Don't steal. Buy the book.
Another thought - that book is not about managed C++. Perhaps as well as being a thief, you're too dumb to read this book anyhow ?

What is the translation of this code from C# to C++ ??
public
String A
{
get
{
return a;
}
}
public
String B
{
get

return b;
}
}
Thank you...

Sorry, can you look to the code again ? It's C# (I pasted the wrong one which i tried to translate)
Replace
public with public :
and
String with String^ ?
I got errors for "get"...

Hi,
I have 2 forms (Form A, Form B). One of them is Parent(Form A), the other one is Child(Form B). Child form has textboxes which users can input smtg. I want to transfer data from Child Form's textboxes to Parent form textboxes. How can i do this ?
I found some articles about Delegates but all in C#, i tried to convert them in VC ++ but everytime i had some errors. I tried to declare a delegate in Form A like:
public ref class Randevu2 : public System::Windows::Forms::Form
{
public:
R2(void)
{
InitializeComponent();
//
//TODO: Add the constructor code here
//
}
public delegate void DelDeneme(String^ s1, String^ s2);
But everytime i had errors. Can any one suggest something or tell me that where i declare delegates?

One approach is you can learn about Design and Patterns like Model-View-Controller.
Another approach that most people around here do is expose the controls as public properties and just set/get the data from one to the other whenever you like, that way they are tightly coupled so that when you want to change something later it's a big mess.

Have you looked at the C++/CLI Beginner articles here on code project? They are highly recommended.

Hi guys,
I want to make an array that consists of system defined colors. I wrote the code
System::Drawing::Color Color1[]={Color::Black, Color::Brown, Color::Red};
what delivered the error
'System::Drawing::Color' : a native array cannot contain this managed type
Then I tried this version
Color Color1[] = __gc new Color[];
and I got this error
error C2440: 'initializing' : cannot convert from 'System::Drawing::Color ^' to 'System::Drawing::Color'
Has anyone an idea how to make this work?
Thanks and best wishes

I would expect this to work...
Color Color1[] = __gc new Color[3];
What about this?
Color Color1 __gc[]= new Color __gc[3];
BTW, this is SO much nicer in VC 2005+ (without the managed extensions)

Thanks but this also doesn't work, it just causes more errors.

Yeah you were trying to use managed extensions (old) syntax so I assumed you
were using VS 2002/2003 .NET.
Since you're not, use the new array syntax (no more __gc) as shown by David Anton.
array<Color> ^Color1 = gcnew array<Color><font color="Red">(</font>3<font color="Red">)</font>;
or
array<Color> ^Color1 = gcnew array<Color>{Color::Black, Color::Brown, Color::Red};
or
array<Color> ^Color1 = {Color::Black, Color::Brown, Color::Red};

Hi Mark,
I tried each of your suggestions, which should, as far as I know, do the same and work, but each caused errors:
array<color> ^Color1 = gcnew array<color>[3];
error C2726: 'gcnew' may only be used to create an object with managed type
array<color> ^Color1 = gcnew array<color>{Color::Black, Color::Brown, Color::Red};
error C3145: 'Color1' : global or static variable may not have managed type 'cli::array<type> ^'
with
[
Type=System::Drawing::Color
]
may not declare a global or static variable, or a member of a native type that refers to objects in the gc heap
error C3145: '$S9' : global or static variable may not have managed type 'cli::array<type> ^'
with
[
Type=System::Drawing::Color
]
may not declare a global or static variable, or a member of a native type that refers to objects in the gc heap
array<color> ^Color1 = {Color::Black, Color::Brown, Color::Red};
error C3145: 'Color1' : global or static variable may not have managed type 'cli::array<type> ^'
with
[
Type=System::Drawing::Color
]
may not declare a global or static variable, or a member of a native type that refers to objects in the gc heap
I really don't know why this doesn't work.

hehe WTH?
What version of Visual Studio are you using?? Are you compiling for clr?

Well, I'm using Visual C++ Express Edition 2008.
What do you mean with compiling for clr?
|
|
|
|
|
This is managed code, so you must use the /clr compiler switch
(Project settings/Configuration Properties/General/Common Language Runtime Support)
