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

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?

How to convert a "void*" to managed class

26-Nov-11 8:15

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;

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,

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".

Best,

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.

Hallo

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

Re: 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?

Not sure but you could try posting a follow up question in the WPF forum, explaining in more detail what you are trying to do.

I tried to recompile the project removing any reference to .NET assemblies and the few lines of WPF code that I added, basically the project is now the original C++/MFC, just compiled with /clr flag active: I get the same error as soon as the app starts, so I guess it's some sort of compatibility issue with one of the libraries I'm using. I'll try to figure out which one is.

It's perfectly possible and acceptable to use the .NET framework with MFC...I did it for quite a while before migrating all my apps to full WPF/Silverlight.

Mixing WPF with MFC may present some challenges. Both are entire GUI systems handling handling native Window handles and associated messaging etc. To have them run simultaneously in the same process? I don't know... Smile | :)
