application error 0x0081aa02

Hi,
I get this error when I tried to save my program: "The instruction at '0x0081aa02' reference memory at "0x00000000" could not be 'read'. Click on OK to terminate the program. Click on CANCEL to debug the program."
Help, please!
Thanks.

Hi analog,

A couple of suggestions:

1. What version of LabVIEW are you using? Are you loading code written in a previous version of LabVIEW into a newer version of LabVIEW and/or using global variables? Refer to KB 2RPC1EHW. When I Update My Code to LabVIEW 6.1 I Get "the memory could not be read" Error.

2. You might not be closing references somewhere in your application. Check where you are using reference numbers: file I/O, DAQ< GAPI, control and VI references, etc.

Also if you are calling DLLs anywhere or ActiveX controls, make sure you you are handling them correctly and not leaving things open.

3. If you're using an older version
of LabVIEW, try upgrading to the latest version 7.1 and see if the problem still occurs. If you do not have the full installation of version 7.1 available, you can download an evaluation copy from our website. Give that a try and see if the problem has been resolved in LabVIEW 7.1.

Thanks and good luck!
