Problem not compiling after renaming project

Hi,

I tried to rename a project and it stopped compiling. After this i made a copy of the project and then renamed manually.

Now i get this:


System.NullReferenceException: Object reference not set to an instance of an object.
   at Visual.Micro.MiroAppAPI.SketchCode.countLines(String what)
   at Visual.Micro.MiroAppAPI.SketchCode.getLineCount()
   at Visual.Micro.MiroAppAPI.SketchBuilder.preprocess(String buildPath, PdePreprocessor preprocessor, Boolean PreProcessOnly)
   at Visual.Micro.MiroAppAPI.SketchBuilder.preprocess(String buildPath, Boolean PreProcessOnly)
   at Visual.Micro.MiroAppAPI.SketchBuilder._build(String lbuildPath, Boolean verbose, Boolean PreProcessOnly)
   at Visual.Micro.MiroAppAPI.SketchBuilder._build(Boolean verbose)
   at Visual.Micro.MiroAppAPI.SketchBuilder.build(Boolean verbose)
   at Visual.Micro.Visual.Studio.Arduino.AddInApp._CompileDo(Project oProject, Boolean IsDebugStartCommand, Boolean isRebuild)
   at Visual.Micro.Visual.Studio.Arduino.AddInApp.CompileDo(Project oProject, Boolean IsDebugStartCommand, Boolean isRebuild)
   at Visual.Micro.Visual.Studio.Arduino.AddInApp.OnBeforeCommandEvent(String sGuid, Int32 ID, Object CustomIn, Object CustomOut, Boolean& CancelDefault)


Any ideas?

Ok, it seems i have to start from a clean project created via VM to get different names. 
No prob.

Hi,

If you right click and rename the project_name.ino visual micro should handle the rename for you.

There is some new caching that might become confused after the rename in which case restart the ide (still to be tested)

The project name, containing folder and a .ino file must all share the same name otherwise visual micro will not attempt to handle the compilation.

Thanks

I suppose the easiest procedure is to create a new project via the VM menu and then copy paste the code to the .ino, and include any .h or .c files the project is using. I did that and it works fine. Otherwise (trying to rename from inside AT7) leads to names inconsistency and makes AT7 or/and VM go nuts.

Did try what I said by renaming the project_name.ino? Did you see the visual micro workflow that executes when you do that?

Hm, no i haven't tried to be honest. When i renamed the project, i don't remember the sequence of the actions i did, perhaps i also renamed the folder from the outside. or the .ino file. I can't be sure. 

It went mad and i' m still a bit anxious about messing with Atmel studio so when i found how to do it properly i didn't tried again.

Everything works fine, VM is great. Now i moved again to my i-5 laptop and it is way more quick than my i-3. 

I program my c++ interface in vs2008 express and the 6 arduino (3 due + 3 uno) with Atmel Studio and Visual Micro.

Everything is rock solid...

Ok great to hear that thanks.

Don't worry to much about renaming. It's easier than it might seem. as long as project, project folder and an .ino file have the same name visual micro should sort itself out. Atmel studio keeps an internal project name so you also have to use the solution explorer to right click and rename a project (not just rename of .ccproj)

Another thing that might help show the simplicity of the visual studio design is to use notepad to edit/view the .sln file. You will see it simply points to one or more project files. If you also use notepad to edit cppproj or the vs vcxproj files they contain the relative paths to the included files. You can copy/edit these files if need be.
