System::[ctrl-space]
returns entries in the tlh from a #import msword.olb, but nothing from the CLR's System namespace.
Doing:
using namespace System;
using namespace std;
then replaces
String^ str;
with
string^ str;
Which isn't the same thing at all, and is getting very annoying!
(I have other namespace problems - but they're all .net types inside MC++. I've looked at creating a project which reproduces this problem, but it was too easy - literally creating a MC++ command line app, typing System::[ctrl-space] gives me the msword.olb methods again. Since this was in a seperate solution, it suggests that the #import headers are being promoted to be system-wide incorrectly and therefore you won't see the same thing. The compiler *doesn't* think the word namespace is available, but does think the system namespace is available)

Here's one:
Any ideas?

Your picture is not loading for me.
Are you using VS2003 or VS2005?
Using VS2005 and a CLR C++ file I have added the code:
static void testTypingString()
{
using namespace System;
using namespace std;
str|
}
At this point I have these 4 suggestions:
Is this similar to what you are seeing?
As a test I tried adding the two variables:
string strLowerCase;
String strUpperCase;
to the function and compiling the code. It fails to compile, since "using namespace std" is invalid. "std" is an unknown namespace. This suggests I might be using the wrong IDE. |

I'm using VS2005
Try #include <vector> to get a std namespace
I'll fix the image tonight, but it was
using namespace System;
using namespace System::Runtime::InteropServices;
except as a bitmap and the underline is curvy and red.
I don't get any suggestions in this case you show, but when I press space after String^, "String" is replaced with "string", unless I turn off 'Repair case'

*ah* yes, adding the vector include fixed the code. Obvious when you point it out 
I had to change the variables to:
string strLowerCase;
String ^strUpperCase;
since it does not like a direct "String" instance, but it compiles quite happily.
That suggests that VA has no knowledge of "String". Simply importing an additional list of symbols should not remove its knowledge of an existing set of symbols *puzzled*
Can you please go to:
VA Options -> About -> Copy Info
and paste the details (from the clipboard) into this thread. This will give us the basic information about your setup.
As for the using statement, I am seeing this:
notice no underlining, the namespace is all blue and all italic.
My current guess, some basic difference in how our two systems are configured, but what difference? |

Looking at where VA was getting information about the system namespace in a new solution, it seems that TLH files in %temp% are being parsed by VA, irrespective of whether they are referenced by the solution. If I delete %temp%\\*.tl? I no longer get any suggestions either for the system namespace, even in a new MC++ project which looks like this:
#include "stdafx.h"
using namespace System;
int main(array<System::String ^> ^args)
{
return 0;
}
I don't think VA should be parsing the TLH unless the import is in the current solution, but this is clearly a seperate problem to the intellisense not working for managed namespaces

I agree, no suggestions in a new project is bad, and this is where we need to start.
On my win2k test system, with VA 1614 and VS2005 I did the following:
Deleted all files that were not in use from %TEMP%, a single zero length .TMP file was left over, which I think we can safely ignore
Create a new "C++ -> CLR -> CLR Console Application" project on C:
Check it compiles, it does
Add a new line in the main function, start typing "String" and suggestions immediately turn up.
I am not having any case correction problems typing "String^"
My project, with a comment telling you what I did is here:
http://forum.wholetomato.com/colin/forumimages/thread_6884_cpp_clr_console_app.zip
can you download and open this project on your machine please, and see what happens for you? At least this way we will know we are both starting from the same point. |

Typing
Strin
gives me a suggestion list starting
string
stringbuf
StringFromCLSID
StringFromGUID2
StringFromIID
stringstream
but no String.
If I have 'correct case' turned on, "String" changes to "string" when I press ^
Typing
String^ x;
x->[ctrl-space]
gives no suggestion list at all.

Can you turn on:
VA Options -> Advanced -> listboxes -> Get content from default Intellisense
and re-try CTRL-SPACE after "x->" please. On paper this "must" work, but at this stage I am half expecting it to fail. |

Yes, that works.
(Normally, I have feacp.dll renamed, but moved it back for this test)

Well that is good news, of a form. At least something is working.
I have just tried the following experiment:
I renamed "feacp.dll" to stop it working.
I told VA to rebuild its symbol database, and closed the IDE.
I deleted the NCB file from the root directory of the CLR C++ project I gave you the link to
After loading this test solution, and letting VA do its parsing, I tried typing "String". This still works correctly for me.
With the code:
int main(array<System::String ^> ^args)
{
Console::WriteLine(L"Hello World");
// type "String^" on the following line
String^ x;
x->|
return 0;
}
At this point pressing CTRL-SPACE produces nothing if I have "Get content from default Intellisense" turned on - which makes sense.
Turn this option off and CTRL-SPACE works perfectly.
Back to basics, if you add "String" manually and place the caret into this type what, if anything, does VA show in its context and definition fields?
How is "String" drawn? For me it is blue (the colour of types) and italic (I have stable symbols in italics turned on).
If you show VA View, place keyboard focus into the editor, and hover the mouse over "String" does VA show you anything in the bottom half of VA View? |

'main' and nothing
quote:

Black (unknown?) and underlined in blue ( = mistyped symbol)
In Console::WriteLine, console is black, underlined in blue, WriteLine is brown (=method), underlined in blue.

No, nor the top. "Files in solution" is populated, but "Symbols in Solution" is empty
If I hover over String, I get a tooltip:
ref class System::String sealed
Represents text as a series of Unicode characters
It's got a 1px gap between the text and the border - I vaguely remember that that has some significance. I do get a refactor button when hovering over String, but clicking it says "Refactoring not available on symbol"

Have you tried rebuilding you VA symbol database yet?
VA Options -> Performance -> Rebuild symbol databases
To be honest I am out of ideas, and if this does not help I am going to ask our developers about this. Everything looks reasonable, and sensible, but it is simply not working. |

Right, log files and developers time. Can you please do the following:
Close the IDE
Open the IDE, but do not load any solutions
Turn on logging, as explained here: http://docs.wholetomato.com?W305
Open one of the small CLR C++ projects
Wait for VA to finish any parsing it wants to do
Try typing "String^ x;", I am expecting to see "String" replaced with "string" here, which is fine, since it is being logged.
Close the IDE and send us the log files via the form:
http://www.wholetomato.com/support/contact.asp
including this thread ID or URL in the description, so we can match it up.
I am hoping this will help to point our developers in the right direction. |

I can confirm that what I presume to tbe 9805 appears to be fixed in 1616 (although I was bemused to see that the suggestions include private members of system types such as String.wcslen - is this intended?)
Thanks
James

VA 1561 and VA 1616 both suggest "String.wcslen" for me.
As a general rule VA will list all members (public, protected and private) since it does not know which items you actually have access to, and which ones you do not have access to.
This is where the icons on the items come in useful (they show the access level, among other things) along with the filtering toolbar. |
