I'm curious as to if anyone else has experienced this and if there is a solution...
We have a fairly large and complex program that runs a variety of functions for us and we've added capability by creating standalone executables (plugins) that we then call as needed.
We have a number of these plugins that have a history of working with no problems. The way they're invoked is by supplying an executable name and path to the main program (let's call it "A.exe") and when the plugin's button is pushed on the menu, the path and name for the exe are sent to the "system exec.vi" (no command line modifiers are being used). The program starts and all is fine.... except for the newest one that I've created - Let's call it "T.exe".
Scenarios:
A.exe - running
- Start T.exe from a command line window that I've opened myself - T.exe starts and runs perfectly.
- Start T.exe by double clicking the icon in Windows Explorer - T.exe starts and runs perfectly.
- Start T.exe using the menu button in A.exe (which launches T.exe using the LabVIEW "system exec.vi" within the A.exe program) - T.exe fails on startup stating it can't find "Get First Matched Node.vi" in "NI_xml.lvlib" along with three other vis from the NI_xml.lvlib showing the same "can't find" error before the main window of T.exe opens with a broken run arrow.
- Created a batch file wrapper to start T.exe
- Call T.bat from a command line window that I've opened myself - T.exe starts and runs perfectly.
- Call T.bat by double clicking the icon in Windows Explorer - T.exe starts and runs perfectly.
- Call T.bat using the menu button in A.exe (which calls T.bat using the LabVIEW "system exec.vi" within the A.exe program) - T.exe fails on startup stating it can't find "Get First Matched Node.vi" in "NI_xml.lvlib" along with three other vis from the NI_xml.lvlib showing the same "can't find" error before the main window of T.exe opens with a broken run arrow.
I have removed the NI_xml.lvlib from "Dependencies" and added it to the main project area under "My Computer" and in the build specification I've made sure to set it to always include the NI_xml.lvlib in the build. This has had no affect on the outcome.
- Created a very small executable (Launcher.exe) that I can call in the same manner as above that then allows me to specify the path and program name for T.exe. Then clicking the "OK" button in there it uses the system exec.vi to launch T.exe.
- Execute Launcher.exe from a command line window that I've opened myself - Launcer.exe starts correctly and then using Launcher.exe, T.exe starts and runs perfectly.
- Execute Launcher.exe by double clicking the icon in Windows Explorer - Launcer.exe starts correctly and then using Launcher.exe, T.exe starts and runs perfectly.
- Execute Launcher.exe using the menu button in A.exe - Launcher.exe starts correctly and then using Launcher.exe, T.exe fails on startup stating it can't find "Get First Matched Node.vi" in "NI_xml.lvlib" along with three other vis from the NI_xml.lvlib showing the same "can't find" error before the main window of T.exe opens with a broken run arrow.
The last scenario would make me think that there's an issue within T.exe since Launcher.exe starts and runs with no problems, but Launcher.exe is incredibly simple compared to T.exe. The problem in T.exe may or may not be related in anyway to not being able to find NI_xml.lvlib methods mentioned above.
Any ideas?
