  • Running CPython Applications With Visual Studio?

    - by user213060
    I would like to know how to use Visual Studio with CPython (the official python.org python interpreter, not IronPython). In particular, I am interested in getting "build" and "run" commands in Visual Studio working. Other features such as color highlighting and auto-complete, I am less concerned about. Also, can the "build" command be made to run py2exe or similar exe packagers?

  • Can I tell git pull to overwrite instead of merge?

    - by Michael Stum
    As far as I see, git pull someRemote master tries to merge the remote branch into mine. Is there a way to say "Completely discard my stuff, just make me another clone of the remote" using git pull? I still want to keep my own repository and keep it's history, but I want to have a 1:1 copy of someRemote's master branch after that command.

  • PHP queue jobs in centOS

    - by Soe Naung Win
    I wrote a PHP shell script which include queuing jobs in centOS with 'at' command. The queue jobs may vary in time and contents which means the system need to keep quite a large number of jobs. The application logic will also be a bit difficult to setup with cronjob. Is there a limit in number of queue jobs in centOS or is there any alternative way of queuing jobs?

  • Using Selenium, how can I test a web UI that returns XML instead of HTML?

    - by Kurt W. Leucht
    I'm using Selenium to unit test my Perl cgi script and all works fine except in one case where my cgi script returns XML content to the web browser instead of returning HTML content. I'm new to Selenium and only pasted in their sample script to get started, but I can't seem to find a Selenium command in any of the documentation that will recognize that my XML response has been returned. The Selenium commands seem to assume that an HTML page is always being returned.

  • Trying to include a library, but keep getting 'undefined reference to' messages

    - by KU1
    I am attempting to use the libtommath library. I'm using the NetBeans IDE for my project on Ubuntu linux. I have downloaded and built the library, I have done a 'make install' to put the resulting .a file into /usr/lib/ and the .h files into /usr/include It appears to be finding the files appropriately (since I no longer get those errors, which I did before installing into the /usr directories). However, when I create a simple main making a call to mp_init (which is in the library), I get the following error when I attempt to make my project: mkdir -p build/Debug/GNU-Linux-x86 rm -f build/Debug/GNU-Linux-x86/main.o.d gcc -c -g -MMD -MP -MF build/Debug/GNU-Linux-x86/main.o.d -o build/Debug/GNU-Linux-x86/main.o main.c mkdir -p dist/Debug/GNU-Linux-x86 gcc -o dist/Debug/GNU-Linux-x86/cproj1 build/Debug/GNU-Linux-x86/main.o build/Debug/GNU-Linux-x86/main.o: In function 'main': /home/[[myusername]]/NetBeansProjects/CProj1/main.c:18: undefined reference to `mp_init' collect2: ld returned 1 exit status make[2]: *** [dist/Debug/GNU-Linux-x86/cproj1] Error 1 So, it looks like the linker can't find the function within the library, however it IS there, so I just don't know what could be causing this. Any help would be appreciated. I get the same error if I type the gcc command directly and skip the makefile, I also made sure the static library got compiled with gcc as well. Edited to Add: I get these same errors if I do the compile directly and add the library with -l or -L: $ gcc -l /usr/lib/libtommath.a main.c /usr/bin/ld: cannot find -l/usr/lib/libtommath.a collect2: ld returned 1 exit status $ gcc -llibtommath.a main.c /usr/bin/ld: cannot find -llibtommath.a collect2: ld returned 1 exit status $ gcc -Llibtommath.a main.c /tmp/ccOxzclw.o: In function `main': main.c:(.text+0x18): undefined reference to `mp_init' collect2: ld returned 1 exit status $ gcc -Llibtommath.a main.c /tmp/ccOxzclw.o: In function `main': main.c:(.text+0x18): undefined reference to `mp_init' collect2: ld returned 1 exit status I am very rusty on this stuff, so I'm not sure I'm using the right command here, in the -L examples are the libraries being found? If the library isn't being found how on earth do I get it to find the library? It's in /usr/lib, I've tried it with the .a file in the current directory, etc. Is there an environment variable I need to set? If so, how, etc. Thanks so much for the help. I've tried a completely different library (GMP) and had the EXACT same problem. This has got to be some kind of Ubuntu environment issue? Anyone have any idea how to fix this?

  • One-Click Application Moving from WinForms to WPF

    - by Tyler
    I have a WinForms app that I recently re-wrote in WPF and I need to release to my end users. I'd like to be able to have the users go to the ClickOnce install point for the WPF application and have their WinForm application removed so they don't have both on their machine What's the best way (read: easiest for users) of accomplishing this? I have thought about creating an prereq command line app to detect the old version and uninstall, but would like to avoid having to write an something like that where it only get's run once.

  • git push current branch

    - by Nocturne
    I use the following command to push to my remote branch: git push origin sandbox If I say git push origin Does that push changes in my other branches too, or does it only update my current branch? (I have three branches: master, production and sandbox). (The git push documentation is not very clear about this, so I'd like to clarify this for good) What branches/remotes do the following git push commands exactly update? git push git push origin ("origin" above is a remote) (I understand that "git push [remote] [branch]" will push only that branch to the remote)
