If I have a native C++ windows program (i.e. the entry point is WinMain) how do I view output from console functions like std::cout?

Update September 2015 (6 years later)
The last release of git-for-Windows (2.5.3) now includes:
By configuring
git config core.editor notepad
, users can now usenotepad.exe
as their default editor.
Configuringgit config format.commitMessageColumns 72
will be picked up by the notepad wrapper and line-wrap the commit message after the user edits it.
See commit 69b301b by Johannes Schindelin (dscho
).
And Git 2.16 (Q1 2018) will show a message to tell the user that it is waiting for the user to finish editing when spawning an editor, in case the editor opens to a hidden window or somewhere obscure and the user gets lost.

launch_editor()
: indicate that Git waits for user inputWhen a graphical
GIT_EDITOR
is spawned by a Git command that opens and waits for user input (e.g. "git rebase -i
"), then the editor window might be obscured by other windows.
The user might be left staring at the original Git terminal window without even realizing that s/he needs to interact with another window before Git can proceed. To this user Git appears hanging.Print a message that Git is waiting for editor input in the original terminal and get rid of it when the editor returns, if the terminal supports erasing the last line
Original answer
I just tested it with git version 1.6.2.msysgit.0.186.gf7512 and Notepad++5.3.1
I prefer to not have to set an EDITOR variable, so I tried:
git config --global core.editor "\"c:\Program Files\Notepad++\notepad++.exe\""
# or
git config --global core.editor "\"c:\Program Files\Notepad++\notepad++.exe\" %*"
That always gives:
C:\prog\git>git config --global --edit
"c:\Program Files\Notepad++\notepad++.exe" %*: c:\Program Files\Notepad++\notepad++.exe: command not found
error: There was a problem with the editor '"c:\Program Files\Notepad++\notepad++.exe" %*'.
If I define a npp.bat including:
"c:\Program Files\Notepad++\notepad++.exe" %*
and I type:
C:\prog\git>git config --global core.editor C:\prog\git\npp.bat
It just works from the DOS session, but not from the git shell.
(not that with the core.editor configuration mechanism, a script with "start /WAIT...
" in it would not work, but only open a new DOS window)
Bennett's answer mentions the possibility to avoid adding a script, but to reference directly the program itself between simple quotes. Note the direction of the slashes! Use /
NOT \
to separate folders in the path name!
git config --global core.editor \
"'C:/Program Files/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
Or if you are in a 64 bit system:
git config --global core.editor \
"'C:/Program Files (x86)/Notepad++/notepad++.exe' -multiInst -notabbar -nosession -noPlugin"
But I prefer using a script (see below): that way I can play with different paths or different options without having to register again a git config
.
The actual solution (with a script) was to realize that:
what you refer to in the config file is actually a shell (/bin/sh
) script, not a DOS script.
So what does work is:
C:\prog\git>git config --global core.editor C:/prog/git/npp.bat
with C:/prog/git/npp.bat
:
#!/bin/sh
"c:/Program Files/Notepad++/notepad++.exe" -multiInst "$*"
or
#!/bin/sh
"c:/Program Files/Notepad++/notepad++.exe" -multiInst -notabbar -nosession -noPlugin "$*"
With that setting, I can do 'git config --global --edit
' from DOS or Git Shell, or I can do 'git rebase -i ...
' from DOS or Git Shell.
Bot commands will trigger a new instance of notepad++ (hence the -multiInst
' option), and wait for that instance to be closed before going on.
Note that I use only '/', not \
'. And I installed msysgit using option 2. (Add the git\bin
directory to the PATH
environment variable, but without overriding some built-in windows tools)
The fact that the notepad++ wrapper is called .bat is not important.
It would be better to name it 'npp.sh' and to put it in the [git]\cmd
directory though (or in any directory referenced by your PATH environment variable).

lightfire228 adds in the comments:
For anyone having an issue where N++ just opens a blank file, and git doesn't take your commit message, see "Aborting commit due to empty message": change your
.bat
or.sh
file to say:
"<path-to-n++" .git/COMMIT_EDITMSG -<arguments>.
That will tell notepad++ to open the temp commit file, rather than a blank new one.

Get-Process -Id (Get-NetUDPEndpoint -LocalPort YourPortNumberHere).OwningProcess
Old answer, cmd
C:\> netstat -a -b
(Add -n to stop it trying to resolve hostnames, which will make it a lot faster.)
Note Dane's recommendation for TCPView. It looks very useful!
-a Displays all connections and listening ports.
-b Displays the executable involved in creating each connection or listening port. In some cases well-known executables host multiple independent components, and in these cases the sequence of components involved in creating the connection or listening port is displayed. In this case the executable name is in [] at the bottom, on top is the component it called, and so forth until TCP/IP was reached. Note that this option can be time-consuming and will fail unless you have sufficient permissions.
-n Displays addresses and port numbers in numerical form.
-o Displays the owning process ID associated with each connection.

Check out Adding Console I/O to a Win32 GUI App. This may help you do what you want.
If you don't have, or can't modify the code, try the suggestions found here to redirect console output to a file.
Edit: bit of thread necromancy here. I first answered this 9ish years ago, in the early days of SO, before the (good) policy of non-link-only answers came into effect. I'll repost the code from the original article in the hope to atone for my past sins.
