Can someone please tell me how to call a C/C++ function that is in a .c or .cpp file from C#?

Dear All, I am trying to call a function from an Intel dll that's originally written in C/C++. It's original prototype is : HIGHGUI_API IplImage* cvvLoadImage( const char* filename ); I have marshalled it as : [DllImport("highgui.dll")] [return : MarshalAs(UnmanagedType.Struct)] unsafe public static extern IplImage * cvvLoadImage(string filename); when I try to run it ,I get the following error.Does anyone know how can I fix that? Error: Cannot take the address or size of a variable of a managed type ('IplImage') I have marshaled the originally struct IplImage into : [StructLayout(LayoutKind.Sequential)] unsafe public struct IplImage { .... }; Best Regards, E.A.

What if I have the following case : struct x (whose structure is unknown) x* a = function(string m); int b= function2(a,....); If I used your idea, will it work in that case? Thanks for your help,I really appreciate it... Best Regards, E.A.

Thanks Christian Unfortunately,it's not a MS one.It's an Intel one. I have already checked the pinvoke documentation and marsalling in msdn but it didn't provide me with examples in my case. do you have any idea what can i do? Thanks and Best Regards, E.A.

HI All, I am trying to call a function from a dll. One of its parameters is a structure that I will need later to call another function from another dll but the problem is that I don't know its detailed structure to be able to marshall it in C#. I am not interested in accessing the struc:confused:ture's attributes,it's a temporary step for me before calling the other function. However,it must be accuartely done in order to pass a correct argument to the other function. Can I just marshal the unknow datatypes within the structure as it they were "void"? Any ideas or suggestions? It's really has been puzzling me for a time now and I can't reach a solution Thanks and Best Regards, E.A.

Dear All, How can I marshall the following attributes in the following structure; typedef struct IplImage {. . struct _IplROI * roi; void * imageid; } where _IplROI is itself a structure? Another question is that the function unmanaged prototype is ; IplImage * cvvLoadImage(const char * filename); do I have to marshall the return type after defining the IplImage or I just write "IplImage *" after marshalling the structure?? Please Help, Thanks and Best Regards, E.A.
