How do I generate a System::Drawing::Color array?
-
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) :) Mark

From the error message, you are using C++/CLI, so what you want is: array ^Color1 = {Color::Black, Color::Brown, Color::Red}; (edited Feb 19 to ignore html tags) David Anton http://www.tangiblesoftwaresolutions.com C++ to C# Converter C++ to VB Converter C++ to Java Converter Instant C#: VB to C# converter Instant VB: C# to VB converter Instant C++: convert VB or C# to C++/CLI Java to VB & C# Converter: convert Java to VB or C# modified on Tuesday, February 19, 2008 10:31 AM

Ack! Good eye - I don't know how many times I read it and missed the "^" LOL Cheers, Mark

The code was mangled when posting (forgot to check "ignore html tags.."). It should be: array ^Color1 = {Color::Black, Color::Brown, Color::Red}; David Anton http://www.tangiblesoftwaresolutions.com C++ to C# Converter C++ to VB Converter C++ to Java Converter Instant C#: VB to C# converter Instant VB: C# to VB converter Instant C++: convert VB or C# to C++/CLI Java to VB & C# Converter: convert Java to VB or C#

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>(3);
or
array<Color> ^Color1 = gcnew array<Color>{Color::Black, Color::Brown, Color::Red};
or
array<Color> ^Color1 = {Color::Black, Color::Brown, Color::Red};
Mark *edit* Fixed the parenthesis above :rolleyes:

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 ^Color1 = gcnew array[3]; error C2726: 'gcnew' may only be used to create an object with managed type array ^Color1 = gcnew array{Color::Black, Color::Brown, Color::Red}; error C3145: 'Color1' : global or static variable may not have managed type 'cli::array ^' 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 ^' 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 ^Color1 = {Color::Black, Color::Brown, Color::Red}; error C3145: 'Color1' : global or static variable may not have managed type 'cli::array ^' 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? Mark

This is managed code, so you must use the /clr compiler switch (Project settings/Configuration Properties/General/Common Language Runtime Support) Mark

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