Re: How to have the Modules like VB.Net to use Public variables & Functions in VC++2010?

28-Dec-11 21:06

Hi,
Actually its my first project in VC++2010. Right now Iam converting my project from C# to VC++2010. In VB.Net I used Modules to use my Public variables and functions to my whole project. And in C# samething I used classes to declare the same accessed in every forms.

Similarly Now I want to use it in VC++2010.. For that any Samples & Codes will be useful for me..

Thanks For the ideas.

It's just the same in C++.

In my c++ project, I use cutePDF to print in non-interactive mode(no save-as dialog) by using GDI print API. The sample code is like below,

DOCINFO di;
ZeroMemory( &di, sizeof(DOCINFO) );
di.cbSize = sizeof(DOCINFO);
di.lpszDocName =L"My_PDF_File";
di.lpszOutput=L"c:\\My_PDF_Folder\\My_PDF_File.pdf";
pDC->StartDoc( &di );

CutePDF geneates PS instead of PDF file. Does anyone know why and how to make it work?

Cheers
Susan

mixed types are not supported

21-Dec-11 22:13

Check your CutePDF installation includes Ghostscript which is the process that does the actual conversion. See also here[^].

Hi,

I need to use "not Managed C++/CLI class" in a Managed C++/CLI class. But I got the "not supported" error message.

Is there a way to do following?

--------------------------------------
class A (){};

public ref class B()
{
A a; <----- not supported

}
-------------------------

Thanks

You could store a pointer to an "A" object in an IntPtr[^].

Thank you very much for the reply. Could you write some sample code?

Best,

Just a guess, something like...

C++

class A (){};

ref class B()
{
public:
    IntPtr APtr;
}

B ^b = gcnew B();
b->APtr = (IntPtr)new A();
A *a = (A*)b->APtr;

How to convert a "void*" to managed class

transoft19-Nov-11 5:37

19-Nov-11 5:37

Hi,

I need to convert a "void*" pointer to a managed class. How can I do it?

Soppose:

----------------
void * pClass

ref class A {};

A^ pA = pClass; <---- compile error

---------------------

Best,

Mark Salsbery20-Nov-11 8:29

Maybe something like...

C++

System::Runtime::InteropServices::GCHandle gch = System::Runtime::InteropServices::GCHandle::FromIntPtr((System::IntPtr)pClass);
A ^pA = (A ^)gch.Target;

Of course, this assumes pClass was obtained from an IntPtr obtained from an actual managed reference to an "A" object...

Hi,

I suggest you to use a dynamic cast :
dynamic_cast msdn[^]

Best regards!

Thank you for your reply.

The classes can not be cast between "Managed" and "un-managed".

To start with, based on your other post....

You must NOT attempt to cast an unmanaged class to a managed one.
Doesn't matter why you think that is a good idea because it isn't.

Why MS design "System::Runtime::InteropServices"?

Is there anyway to stream a file stored in a database directly to an AxAcroPDF control?

That provides a way to proxy between the two.

Is there anyway to stream the file directly from the database to the AxAcroPDF control without first saving the file on the hard drive?

Error executing C++ project compiled with /clr flag

Hi all, I'm Francesco and that's my first post here. As stated in the subject, I'm having trouble compiling an existing C++ project (an MFC app with many other libraries linked) with the /clr flag. I'm using VS08 sp1 and Win7 64 bit and framework 3.5.
The projects compiles succesfully, but trying to launch (both in release and in debug) I get an error message:

"Application Error : The application was unable to start correctly (0xc000007b)."

I tried to google for the error, someone suggests to run sfc /scannow to repair a possible system problem, but it doesn't find anything wrong.
Any suggest?
Many thanks in advance,
Francesco

Why are you using the /clr flag for an MFC application?

I'd like to use some of the .NET features (in particular WPF) from within the app. It seems to be some compatibility issue with one of the libraries used in the project: any chances that someone has encountered a similar problem before?
