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.

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)

Also, I fixed the code in my last post - maybe that will work better.
Sorry about that

From the error message, you are using C++/CLI, so what you want is:
array<system::drawing::color> ^Color1 = {Color::Black, Color::Brown, Color::Red};

The code was mangled when posting (forgot to check "ignore html tags..").
It should be:
array<System::Drawing::Color> ^Color1 = {Color::Black, Color::Brown, Color::Red};

The only thing that's urgent is you urgently need to stop trying to learn how to do EVERYTHING through internet forums. Most software developers go to university and read books to learn fundamentals of software development. If you refuse to learn fundamentals there is no hope you will ever be a capable developer.
