Accessing shared memory location

[matdlew]

I have a space of shared memory that another application has created with a constant handle. How can I get Labview open up this space of memory without having to write a CIN?

Hi,

There is no built-in LabVIEW functionality to access shared memory. Although you do not have to use a CIN, you will probably have to use a DLL. There is documentation on Microsoft’s site:
MSDN.com: Using Shared Memory in a Dynamic-Link Library


You'll want to use a file-mapping object to set up memory that can be shared by processes that load the DLL.

There are also a couple discussion forum posts that provide some examples from other customers who have tried this:

DF: Communicating Between Built LV Apps
DF: How can I create a DLL with LabWindows/CVI with shared memory?

Hope this helps. Good luck!
