As far as I see search and replace in more than one file is not possible inside of TeXnicCenter (searching inside of one file is, though). For that you need to change to another text editor. Searching only is possible over the menu “Search” and the menu entry “Find in Files” or by pressing Ctrl+Shift+F. It does exactly what it says: It lists the findings of a given pattern (“Find what”) inside of given files or file types (“In files/file types”), which are located in a selected folder/directory (“In” - you can select, that subfolders are searched, too, but it seems, it’s the default), no more, no less.
Text editors for Windows where I know, that, what you want, is possible (I’m sure there are more):
(All off these with syntax highlighting for TeX files)
I have seen problems like this before. They could be related to:
1) As @Sigur suggested, this could be due to bad configuration.
1.1) I once saw this behavior when the TeXnicCenter distribution was saved in "Programas" (in spanish) instead of "Program files". Maybe if you reinstall it where it is supposed to go you won't have more problems.
1.2) As @Speravir mentioned, you can always change this manually. Go to Build/Define Output profiles in the main menu bar. Select "LaTeX-->pdf" on the left section of the window. On the "(La)TeX" tab make sure the "Path to the (La)TeX compiler" is actually where the pdflatex.exe file is located. If using Windows it should look something like this: C:\Program Files (x86)\MiKTeX 2.9\miktex\bin\pdflatex.exe. Of course, it is dependent on where the file is located in your computer. Make sure you are also pointing to the right bibtex.exe file in the bibtex section, as well as the makeindex.exe
2)You are using Adobe Reader X or XI and you have to change your viewer settings:
For this, go to Build/Define Output profiles in the main menu bar. Select "LaTeX-->pdf" on the left section of the window. Once there, go to the "Viewer" tab and make sure the "server" says acroviewR10 (if using Adobe Reader X) for all of the entries: View Project's output, forward search and close document before running (La)TeX. Also, as in point 1), make sure the executable path is where the reader.exe is located. Once again, if using Windows, it should look something like this C:\Program Files (x86)\Adobe\Reader 10.0\Reader\AcroRd32.exe.

You need a project in order to have a visible "structure." Moreover, this terminology has been updated and is now referred to as an "outline." And, with each project, there is an associated "main file." It's this file that TeXnicCenter starts with in order to build the outline view. To show the TeXnicCenter outline of a project, use Ctrl+Alt+O (or via the menus View > Tool Windows > Outline).
Note that the outline displayed requires a specific format for your files. That is, TeXnicCenter parses the main project file with every "Save" operation (but not if it autosaves before you compile!), including any subsidiary (included files). For example, if you have a project that has a main file
latex_stuff.tex
:together with
myinput.tex
:it will render in the project outline as
See how the project only displays the caption of the labelled float (

), while thetable
is left blank. Moreover, if you define your own environments or macros with names other than the default ones, they won't be picked up by TeXnicCenter.
