Problem with XControl and remote debugging
Solved!
Can you make a remote debugging connection to an EXE or DLL that uses an XControl? So far, my experiments would indicate the answer is no, but I find this surprising and have seen no previous mention of it in bug reports or in the forums. When trying to connect to the DLL with XControl, I get a "Fatal error occurred during operation, closing connection" error dialog. I am simply connecting from the local machine- not over the network.
My actual application is a rather elaborate DLL that is called from a Visual Studio 2008 C++ app and launches LV panels dynamically. I realized that my DLLs that include panels with XControls are not allowing remote debugging to connect, while DLLs without XControls work fine. This is the only difference between the two projects.
I simplified this to a very simple test program that simply updates one indicator in a timed loop. I created two versions of the VI, one which updates a simple numeric, and another which updates an XControl (which itself is a simple numeric- only change from XControl template is dropping a numeric indicator onto the Facade FP and updating a local variable to it in the Data Change event). I then built these two VIs into EXEs and tried to make a debugging connection to each after launching the EXE. Sure enough, the app with the XControl gets the error dialog mentioned above. Any ideas on why this is happening?
I've attached the sample project that builds the two EXEs. One is called Test Debugging with XControl, and the other Test Debugging without XControl. My LV ver. is 9.0f2. Here is the very simple diagram demonstrating the problem:
