Insert or Update a path from textbox...

Hi,

I'm just try to insert or update an actually table with Microsoft .NET platform VS2005.

The problem is that de "\" dissapear when I make the insert or Update.

If i debug the object has all detailed path...so Why is not saved on the table.
The type of column is character (100).

So:

I have: C:\EVOL\Carga\
I obtain on table of the postgresql: c:EVOLCarga.

Is an X-File?

If anybody can has any idea...

Thanks.
