Hi Mike,
Just so you know, I first learned programming using assembly on a state of the art Intel 8085 and our operating system was CP/M (that's what it was called before Microsoft bought it and renamed it MS-DOS). Over the years I have been forced to learn various programming languages on Data General, VAX, UNIX, and MS-DOS boxes, but all of the OO stuff was invented long after I got out of college. So the fact that I'm an over 50 microelectronics engineer with a EE degree and not a new Computer Science graduate, I can state with confidence that with the exception of Object Oriented Design Principles I've never heard of any of those terms before (nor whatever MVC means). You even mention a "presentation layer". I have never heard anyone use that term before. IO, User Interface, GUI sure, but "presentation layer"? I don't understand what you mean by "you don't tightly couple a class with the presentation layer". Visual Studio's forms designer seems to make things very tightly coupled. Anyways, if you could dumb down your responses for me that would be cool.
Thanks,
Old Buck
And my applications always work and do what they were designed to do.

Easy way would just be to make a new form class and make the class a member of the new form class. ugly? yes. best practise? no. will it do the trick? probably

How To create an array of form?
|
|

You create form array in the same way as you would create array of any other type.

Still another question:
I want to create a .NET equivalent to the MFC CDialogBar.
When I move a form which is a child of a panel,
the mouse position is bounded by the panel,
even if I set
Parent = nullptr;
TopLevel = true; on first Move-Event and even if the panel is not
visible any more. Is there a workaround?

Hello!
For the mouse, I found a solution:
The allowed mouse position is bounded by the Cursor->Clip property.
But still the window can not be moved completely out of the panel,
it stops at the border.

Ok, nearly solved.
When I override the WndProc-Method and process the WM_SYSCOMMAND(SC_MOVE) Message,
I can reset the Parent-property and the window is not bounded any more.

Hello!
I want to compare the type of an object to a class.
What is the correct syntax to use? In my case, I
want to know if a control is an instance of MdiClient.
GetType works on the pointer, but not on the class.
typeid(MdiClient) gives me error C3767.

if (some_ref_handle->GetType() == MdiClient::typeid)
{
}
|
|
|
|

Thank you!
At first I got an error because MdiClient is a private(?) member
of the class (which is not shown in the IntelliSense list).
But with
Windows::Forms::MdiClient::typeid
it works.

Cool

MdiClient IS the class.

Oops - I guess I assumed "using namespace Windows::Forms;"
typeid needs to know the type at compile time. You could also use something like
if (some_ref_handle->GetType() == Type::GetType("Windows::Forms::MdiClient"))
for a runtime check.
Cheers,
Mark

Hello!
::MdiClient::typeid works, but MdiClient::typeid
gives
error C3223: 'System::Windows::Forms::Form::MdiClient' : you cannot apply 'typeid' to a property
Alex

MdiClient is in the System::Windows::Forms namespace, not the
System::Windows::Forms::Form namespace (which doesn't exist -
System::Windows::Forms::Form is a class).
Either of these should work:
using namespace System::Windows::Forms;
...
if (objectref->GetType() == MdiClient::typeid)
or
if (objectref->GetType() == System::Windows::Forms::MdiClient::typeid)

Dear experts,
I have the following problem.
I have "C++ - unmanaged code" and I want to use it in my managed C#-Applications. Therefore I have a "managed C++" - wrapper around my "unmanaged C++ - Code"
At the end I have the following "call-sequence"
"Managed C#" -> "Managed C++" -> "Unmanaged C++"
All works fine, but the problem beginns at debugging the unmanged C++-Code.
a) I cannot step-into the "unmanged C++-Code"
b) The unmanged objects are not expanded in the debugger
Does somebody have any advice?
Kind regards

|
|
|
|
Ok,
I found the solution the "stop-into"-Problem by Myself: Just the the debugger-option to: "Enable unmanaged code debugging".
What remains is the second problem: The unmanaged objects are not expanded.
Kind regards
|

|

Hallo,
I found another part of solution.
If I set for all 3 components the debugger-option to "mixed mode" than I can expand the "unmanged objects" in the "managed C++"-Wrapper )))
But I still cannot expand my "unmanaged C++"-objects in my "manged C#"-Code.
I fear, this is not possible due to totally different languages
Kind regards

I have a project written in C++,and I want to use the .NET framework as the architecture in the next version. Rewrite all the code in C# is impossible, so I give my attention to C++/CLI.
I have less understanding about this tech, I only know these points about it:
1.The original C++ code can be compiled in the C++/CLI compiler
2.I can use all of the C++ function in the new platform
3.I can use all of the .NET framework function in my C++ code
4.For deploy issue, I will only need to install the .NET framework will my application, then everything could be OK
Are there any other things need to be noticed?

You may need to deploy additional things used by your C++ code, like MFC and/or the CRT libraries.
You should also understand interop between native and managed code, if it applies.
