Tough question, please help a fellow programmer

[Cipherous]

great board btw,

I am working with some old com files which require data stored in byte arrays and I need to do this

I have the following:

int memoryAddress; //this is where the starting data is stored, its a file
int sizeOfFile;//size in terms of bytes

I need to assign a byte pointer to wherever address the file is

so I want to do this

byte* myData = whateverIsAtMemoryLocation (memoryAddress);

after that, I want to convert that file to a byte array so that I can store it else where

byte[] newData = new byte [sizeOfFile];

for (int i=0;i<sizeOfFile;++i)
newData[i]=(byte)(myData+i);


can anybody please help? when you go myData++, does it go to the next byte in memory? or does it do something else?

my gratitude in advance.

also, does anybody know how to print out the memory address of a pointer?

I tried

MessageBox.Show ("Address of Pointer: "+&myPointer);

and that doesn't compile

I tried

MessageBox.Show ("Address of Pointer: "+(int)(&myPointer));

can anybody help?

For (2) Have a look at the 'fixed' keyword - this may fulfill your needs.

For (1), if you've got a pointer to a block of memory use the

System.Runtime.InteropServices.Marshal.Copy

methods to copy to and from unsafe, unmanaged memory into managed memory.

See no big deal.
