How to share HGLOBAL with another application?

Question

I\'m trying to understand something about HGLOBALs, because I just found out that what I thought is simply wrong.

In app A I GlobalAlloc() data

Answer 1

Read the documentation. With the introduction of 32-bit processing, GlobalAlloc() does not actually allocate global memory anymore.

To share a memory block with another process, you could allocate the block with GlobalAlloc() and put it on the clipboard, then have the other process retreive it. Or you can allocate a block of shared memory using CreateFileMapping() and MapViewOfFile() instead.
