LaTeX.org

I think you just need to specify the correct directory for pdflatex.exe. This is done thru the TXC main menu:

Build->Define Output Profiles
or the hotkey is Alt-F7.

Click on "LaTex=>PDF " in the profiles box and then enter the correct dir info in the (La)Tex tab.

Hope this helps.

Couldn't you just define a suitable build profile

Build->Define out profiles...->Add

To get what you want? E.g. I defined new profiles like

Latex=>DVI(Simple)

which do NOT call BibTex or MakeIndex because I did not want to see all the error messages triggered when these utilities all called on ...

Tools->Options->Text Format->Show line numbers

The show line numbers check box is the very last one at the bottom of the dialog.
