WPF is a separate UI system from Windows Forms. You can't just plop a WPF
canvas on a form. You can host WPF content in a form, however...

Hi All,

How does one export a function (not a class) in a managed Dll?

I'm catching a System.EntryPointNotFoundException. dumpbin confirms that the Dll is not exporting the function.

Does not work:
* declaring method as public: error C2059: syntax error : 'public'
* __declspec( dllexport ): incompatible with /clr and /clr:pur
* .def file: fatal link error LNK1310: Exports not supported for pure MSIL image

Thanks,
Jeff

how to set MaximizedBounds?

5-Aug-08 10:56

Wrapping in a public class is one option:

////////////////////////
// Test Header
//bool Test( array<byte>^ );
public ref class StaticFuncs
{
public:
	static bool Test( array<byte>^ a ) 
	{
	...
	}
};

////////////////////////
// Test Implementation
////////////////////////
// Test Implementation
//bool Test( array<byte>^ a ) {...}

Hi,
i want to write a MDI application with 3 child windows. The left and right ones are fixed tool windows. The middle one should be moveable and sizeable between these other to child windows.
But if the user would maximize the middle Window it would maximize the the hole client area.
I tried something like that:

System::Drawing::Size szMax;
szMax.Width = 500;
szMax.Height = 300;

_middleChildWindow_->MaximumSize = szMax;

Rectangle boundRect(100, 10, 200, 200);
vcHG->MaximizedBounds = boundRect;

but I get following error

error C3767: "System::Windows::Forms::Form::MaximizedBounds::set": Auf mögliche Funktion(en) kann nicht zugegriffen werden.
(means the function cant be accessed)

Why is that? The function is protected so I should be able to access it.

I also don´t know how to prevent the user from moving the middle window over the other child windows.

I would appreciate any help
Thanks

I have no idea what type vcHG is but the following code compiles for me in VS2005 where this is a System::Windows::Forms::Form

System::Drawing::Rectangle rect(10,10,10,10);
this->MaximizedBounds = rect;

First off you are in the wrong forum. None of your questions are about managed or mixed mode development which this forum is intended for as one might see if they READ the first message in the forum.

Second, one interpretation of your collection of posts is that you believe the way to learn about subjects is to ask people in internet forums to teach them to you. In my opinion this about the worst way to attempt learning a subject. A more efficient method would be to read the documentation or even buy a book that covers the subject. Also there is a mountain of articles and blog entries on the internet that might provide introductory type explanations of subject. One can happily find them by using Google to search for them. There are actually a lot of these articles on CodeProject, the CodeProject articles are a primary purpose of this site. Look through the "CHAPTERS" menu on the site. Then once you have at least a beginner level grasp of the subject people in forums might be able to help you with specific problems if/when you get stuck on something.

Let me answer your question one by one:
I dont think all my questions are irrerevelant to the group.

Secondly thanks a lot for your interpretation that i ask people questions and learn .If my intention is that then i would join some classes rather that posting questions in the forum .
I can buy books thats again a good thought but let me make it clear to you that had i not read any books then i would not even be coding , or rather my questions are not soo preliminary
and thirdly searching on the google , i have been searching for these questions but when i could not find appropriate ans i ask questions here

Please for gods sake help people but do not tell them what to do.
You could have put the same thing in a better way or rather you could have directed me to the correct group which you haven't this clearly shows that you like to rebuke ppl,
its always easy to point mistakes but difficult to help others.

Look, you've been a member of this site for 6 months. I know what's going on here far better than you do. I suggest that you listen to me rather than argue with me. You have posted this question IN THE WRONG FORUM, period. Figure it out or get lost, either way I don't care.

removing unused registry keys

Re: removing unused registry keys

Hi ,
I want to write a sample application for registry cleaning.
I wanted to know how do we decide if a particular registry key is invaid or not so that we can delete the key.
How do we search for invalid registry keys.
I am using c++
Thanks,
Gayatri

Re: removing unused registry keys

The keys under HKEY_CLASSES_ROOT are pretty well defined - you can
cleanup orphaned file/type associations relatively easily.

Beyond that I'm not sure how much you can reliably do. There's no magic
APIs that will tell you if an item in the registry is still being used.

I do know you can make your system unusable very easily Smile | :)

Good luck!

Thanks for you answer.
It would be nice of you if you cold tell me how will is the relation mainitained for the keys which are being used .
I am novice to it,so it would be great if you could explain it with an example.

Thanks

If this isn't a Managed C++ question (using .NET) please direct your question to C++ Forum[^]. If you are using the managed libraries, you can use the System.Diagnostics.Process[^] class to get the Threads[^] that belong to that process.
