"<<<<<<< .mine". Illegal characters in path.

Could you give some more information? Perhaps include the section of code you're using?

I can't give more information. Visual Studio doesn't offer more information, only this error description.

Conflicts are resolved with TortoiseSVN.

Search for "<<<<<" in the whole solution

Just Revert it by SVN menu (Recommend you should have a backup version of the file before)

it'll come back to last version

then change your code manually to what you want

then Update again

to libin_v

There wasn't "<<<<<" in the whole solution

to trunghieubkit

I have revert

I wanted nothing to change, so I did nothing

I updated

and the problem is solved...

But why this happends? I want to understand a little more this error, because it happends quite often in our team. (I solved it as usual with backup, checkout and manually copy-paste my code to new version)...

Does anybody has some more insight in this error?

This happens when you update from SVN Server. Tortoise tries to merge your local changes with the the working version in SVN Server and fail. Unfortunately, Tortoise doesn't remove the marking character <<<<<<< .mine in these files.

So, that's a bug in SVN? (incompatible with Visual Studio environment)?

>> Tortoise doesn't remove the marking character <<<<<<< .mine in these files

I can't find it in the files

That's possibly a bug of Tortoise.
Error      49      Files has invalid value "<<<<<<< .mine". Illegal characters in path. --> Does VS specify which files ?

No, VS does not specify it.

How do you know that it's a bug of Tortoise?

It's not a bug of SVN,
