Desktop charting problem #1204

Closed taylerallen6 closed 6 years ago

taylerallen6 commented 6 years ago

Hey, I am having trouble charting the desktop version of LEAN in visual studio 2017. I followed all the steps in the "Using a Desktop User Interface" video at https://www.quantconnect.com/tutorials/desktop-charting-with-lean/ but I am still getting an error.

This is the error I am getting:

Exception thrown: 'System.ComponentModel.Win32Exception' in System.dll

An unhandled exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll

The system cannot find the file specified

'QuantConnect.Lean.Launcher.exe' (CLR v4.0.30319: QuantConnect.Lean.Launcher.exe): Loaded 'C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\Common7\IDE\Remote Debugger\x64\Runtime\Microsoft.VisualStudio.Debugger.Runtime.dll'. Skipped loading symbols. Module is optimized and the debugger option 'Just My Code' is enabled.

It also highlights line 103 in file Quantconnect.Lean.Launcher which says "Process.Start(info);"

These are my config settings:

  1. "environment": "backtesting-desktop",
  2. "algorithm-type-name": "BasicTemplateAlgorithm",
  3.  "job-user-id": "#####",
  4.  "api-access-token": "######....####",

Has anyone else had this problem?

I figured out the problem. I changed "desktop-exe": "../../../UserInterface/bin/Debug/QuantConnect.Views.exe" to "desktop-exe": "../../../UserInterface/bin/Release/QuantConnect.Views.exe" in the config.json file.

 

There is a better explanation here:

Thanks for posting solution back @taylerallen6. It depends on whether you build it in release or debug mode

I have QuantConnect.Views.exe in ../../../UserInterface/bin/Debug/ but the problem persists

@kievking change the path to the location of your desktop build. If there is no desktop executable then it's not building for some other reason. All of this will be deprecated and removed soon we're just looking for the right person to build the electron application =)

Any user / application specific issues should be posted to the LEAN Discussion Forum, not the Github issues list which is generally for systematic issues.

@jaredbroad I think this software isn't built for mac. it's so many problems.
