Intellisense not working.

I must be doing something wrong.  I can't get intellisense to work in either Visual Studio or Amtel Studio.  I tried the suggested remedy of removing and reinstalling Visual Micro to no avail.  I am running Visual Studio 2008 and am developing code for the Arduino Due.

Hi Dave,

If you switch to another boards such as the Uno then switch back to the Due does intellisense then work correctly?

If not then please close the ide, saving the project and solution then zip and email the sketch folder with sub folders to info[at]visualmicro.com. Then e can see your config.

Thanks

Changing the board type had no effect.  I tried to send  a zipped copy of the project folder as an attachment but I got

The file Mag_Loop_Antenna.zip (1044 KB) is too large. The maximum allowed filesize is in KB: 250

The debugger and serial output work just fine.  The main loop responds to volatile flags set by the interrupt service routines and the interrupts are triggered by manually rotating a rotary encoder so the frequency of the breakpoints and serial messages is very low.  My main issue is when editing the code I can't take advantage of the Intellisense feature which displays the methods and data types available to the typed variable.

David, apologies I have had a number of different discussions come up today and I got confused with my response to you.

The intellisense worked fine for me. Maybe a corrupted vs intellisense file.

Close the Ide, and please delete the .ncb file in the project folder then re-open

Cheesy Thanks Tim, deleting the Intellisence DB file did the trick.

I've found that I have to delete the Intellisense DB file each time I restart Visual Studio in order to get it to work.  Just thought you ought to know.

Hi David,

I have never heard of this and it doesn't happen with my Visual Studio 2008.

What is the full version number from the help>about?

Next time it happens please close vs and zip and email the sketch folder before zapping the ncb.

It might also be useful to know that Visual Micro has no control over the ncb. The file is a part of the VS 2008 C++ system and is created automatically by Microsoft based upon the various project and code settings. So this is a VS 2008 C++ issue. I am happy to try to help but just explaining things so you know where to look.

Thanks

Hi Dave,

Thanks for all the info. 

Please try setting Content=True for the .ino files then click save

The 'Content' property is in the property tool window when clicking a .ino file in the solution explorer. 

The property window is actually the same window as the one used to set Visual Micro project properties but instead of selecting the project name you select the .ino file name in the solution explorer.

Does intellisense start working immediately after clicking "Save" or when re-opening the solution without deleting the ncb?

Thanks

I tried setting Content true for all five of the ino files in the solution and after about five open-close-open cycles intellisense failed.  I went through an additional ten cycles to see of intellisense would spontaneously recover, but it didn't.
It is interesting to note that if I type control-j when entering a variable name, the intellisense drop-down does appear, it just doesn't do it automatically.

Oh I didn't realize intellisense was still working. 

So it's just failing when, for example, you press the . after Serial?

If so then what happens if you press CTRL+J after adding the '.'?

Thanks

Oh I might (hope) have found the problem and solution.

There are a couple of differences between vs versions and there is an optional Visual Micro feature that forces the project to refresh the intellisense more often. You probably won't notice a difference in usage speed.

Set "Tools>Options>Visual Micro>Intellisense>Always Re-Add Header=True"

I'll force it on for vs2008 in the next release!

Thanks

If type control-j after typing the period, I get the normal intellisense drop-down.  When I tried to test this just now, the automatic drop-drop down worked without my having deleted the database file first.  The corrupted file thing was probably a red herring and what we're seeing is, most likely, sporadic behavior.  I looked for "Tools>Options>Visual Micro>Intellisense>Always Re-Add Header=True" but the only subheading I could find under Visual Micro is "General".

Hi Dave,

Please click into the General list of options and find the option called "Always Re-Add Header"

Thanks

Found it, thanks.  I particularly liked the option "Stop trying to sell me stuff".  You are a cheeky lot.  Changing  "Always Re-Add Header" to True didn't fix the problem.  But given that I can always type control-J to get the intellisense drop-down, the intermittent loss of the automatic drop-down is no big deal.

Thanks, seeing you have bought a licence the "stop trying to sell me stuff" option doesn't do anything for you because you are fully licensed. It only applies to people who don't buy and will probably be removed in future releases  Smiley
