• Why does eclipse break when the .project file is hidden?

  - by Tommy

  Why does eclipse break with the error "Could not write file: M:\workspaces\eclipse\project.project. M:\workspaces\eclipse\project.project (Access is denied)" when the .project file is hidden (on the Windows file system)? Note: This happens w/ other files as well. Steps to Reproduce: 1. Install the latest eclipse, I am using eclipse-jee-galileo-SR2-win32.zip. (Not sure if it happens in other versions) 2. Create a project. 3. Browse to the project in windows explorer, find the .project file. 4. Right click - properties 5. Under Attributes check hidden. 6. In eclipse, open the .project file, make a change and try to save. 7. After you get the error, uncheck the hidden box and save again.

• BASH Install Of Wordpress, Without Visiting wp-admin/install.php

  - by user916825

  I wrote this little BASH script that creates a folder,unzips Wordpress and creates a database for a site. The final step is actually installing Wordpress, which usually involves pointing your browser to install.php and filling out a form in the GUI. I want to do this from the BASH shell, but can't figure out how to invoke wp_install() and pass it the parameters it needs: -admin_email -admin_password -weblog_title -user_name (line 85 in install.php) Here's a similar question, but in python #!/bin/bash #ask for the site name echo "Site Name:" read name # make site directory under splogs mkdir /var/www/splogs/$name dirname="/var/www/splogs/$name" #import wordpress from dropbox cp -r ~/Dropbox/Web/Resources/Wordpress/Core $dirname cd $dirname #unwrap the double wrap mv Core/* ./ rm -r Core mv wp-config-sample.php wp-config.php sed -i 's/database_name_here/'$name'/g' ./wp-config.php sed -i 's/username_here/root/g' ./wp-config.php sed -i 's/password_here/mypassword/g' ./wp-config.php cp -r ~/Dropbox/Web/Resources/Wordpress/Themes/responsive $dirname/wp-content/t$ cd $dirname CMD="create database $name" mysql -uroot -pmypass -e "$CMD" How do I alter the script to automatically run the installer without the need to open a browser?

• How to display the properties of a Scheduled Task?

  - by TooFat

  I have C# app that uses a Form to set a bunch of settings. Those settings can be read by a Console App so it can run via the built in Windows Task Scheduler. I would like to be able to simply open up a scheduled task as if I had just opened it from the gui in Windows so the user can set all the settings for the scheduled task. I know I can use a library like http://www.codeproject.com/KB/cs/tsnewlib.aspx but I would rather not have to recreate all the options in a WinForm when everything is already available in Windows. Does anyone know how I can programattically display the built in Windows Task Scheduler from C#?

• form not showing

  - by Luke

  Perhaps this has something to do with it being the mainForm, but I'll ask the question. I have my mainForm that is the first to load when the program is booted. I then click a button called Add, which should open a new form, and close the mainForm. The problem is, is shows the new form for a split second, then closes both. The code: private void addFrmBtn_Click(object sender, EventArgs e) { saveForm saveform = new saveForm(); saveform.Show(); this.Close(); }

• fwrite to txt-file

  - by timkl

  I'm currently trying to write to a txt-file with PHP, I've found this small script: <?php $filename = 'testFile.txt'; $somecontent = "Add this to the file\n"; if (is_writable($filename)) { if (!$handle = fopen($filename, 'a')) { echo "Cannot open file ($filename)"; exit; } if (fwrite($handle, $somecontent) === FALSE) { echo "Cannot write to file ($filename)"; exit; } echo "Success, wrote ($somecontent) to file ($filename)"; fclose($handle); } else { echo "The file $filename is not writable"; } ?> I get a success-message, but nothing is written to the file. Even if I delete the txt-file I still get the success-message Does anybody know how to troubleshoot a situation like this?

• Shutting Down SSH Tunnel in Paramiko Programatically

  - by PlaidFan

  We are attempting to use the paramiko module for creating SSH tunnels on demand to arbitrary servers for purposes of querying remote databases. We attempted to use the forward.py demo that ships with paramiko but the big limitation is there does not seem to be an easy way to close an SSH tunnel and the SSH connection once the socket server is started up. The limitation we have is that we cannot activate this from a shell and then kill the shell manually to stop the listner. We need to open the SSH connection, tunnel, perform some actions through the tunnel, close the tunnel, and close the SSH connection within python. I've seen references to a server.shutdown() method but it isn't clear how to implement it correctly. Any help would be greatly appreciated...

• Android - Connectivity Questions

  - by Donal Rafferty

  I have a couple of questions about connectivity on Android, if anyone has any insight it would be great. What is the default when an application wants to wirelessly connect? Is it wlan? And if wlan is switched off or there is no access points around is it 3g or gprs? Is a device always ip connected? Or when its disabled from wlan or 3g does it lose its ip address? Is an application, for example the browser only ever connected to one ip address? Or can it be connected to multiple addresses for each radio such as gprs or wifi (wlan)? Can an application decide which connection to open a socket to? For example can I create an application and decide whether to connect the socket to the wlan or gprs? Or does the OS decide? Finally how do native applications handle connectivity? In the same manner?

• VC++ 2010 wants to link boost libararies i didn't even specify

  - by Philipp

  Hi there, I'm trying to build my application with MSVC 2010 instead of GCC. With GCC everything works fine. My app uses boost_system and boost_thread libraries. I built boost with VC2010 in "system" layout, that means the libraries are named just libboost_system.lib (and not libboost_system_compiler_threading_version_wtf_snafu.lib) The libs reside in C:\Boost\lib, the Makefile specifies LFLAGS = /NOLOGO /INCREMENTAL:NO /SUBSYSTEM:CONSOLE LIBS = /LIBPATH:C:/Boost/lib libboost_system.lib libboost_thread.lib Ws2_32.lib when invoking nmake it compiles, but when trying to link it quits with LINK : fatal error LNK1104: cannot open file 'libboost_date_time-vc100-mt-1_43.lib I mean seriously, WTF? I told it to link libboost_systen.lib and libboost_thread.lib how come it tries to link libboost_data_time and why does it assume I built the libs in "tagged" layout?? How can I stop MSVC trying to be smart and guess what I might have wanted to link? Thanks, Philipp

• Exit Tks mainloop in Python?

  - by Olof

  I'm writing a slideshow program with Tkinter, but I don't know how to go to the next image without binding a key. import os, sys import Tkinter import Image, ImageTk import time root = Tkinter.Tk() w, h = root.winfo_screenwidth(), root.winfo_screenheight() root.overrideredirect(1) root.geometry("%dx%d+0+0" % (w, h)) root.focus_set() root.bind("<Escape>", lambda e: e.widget.quit()) image_path = os.path.join(os.getcwd(), 'images/') dirlist = os.listdir(image_path) for f in dirlist: try: image = Image.open(image_path+f) tkpi = ImageTk.PhotoImage(image) label_image = Tkinter.Label(root, image=tkpi) # ? label_image.place(x=0,y=0,width=w,height=h) root.mainloop(0) except IOError: pass root.destroy() I would like to add a time.sleep(10) "instead" of the root.mainloop(0) so that it would go to the next image after 10s. Now it changes when I press ESC. How can I have a timer there?

• Generic test suite for ASP.NET Membership/Role/Profile/Session Providers

  - by SztupY

  Hi! I've just created custom ASP.NET Membership, Role, Profile and Session State providers, and I was wondering whether there exists a test suite or something similar to test the implementation of the providers. I've checked some of the open source providers I could find (like the NauckIt.PostgreSQL provider), but neither of them contained unit tests, and all of the forum topics I've found mentioned only a few test cases (like checking whether creating a user works), but this is clearly not a complete test suite for a Membership provider. (And I couldn't find anything for the other three providers) Are there more or less complete test suites for the above mentioned providers, or are there custom providers out there that have at least some testing avaialable?

• Geocoding autocomplete bias not working

  - by chris

  I'm using the following code to get the autocomplete functionality for an address input box using Google Maps API v3: function initializeAutocomplete() { var defaultBounds = new google.maps.LatLngBounds( new google.maps.LatLng(1.484016,103.575212), new google.maps.LatLng(1.233592,104.033618)); var input = document.getElementById('destStreet'); var myOptions = {bounds: defaultBounds, types: ['geocode']}; autocomplete = new google.maps.places.Autocomplete(input, myOptions); } The problem is that biasing doesn't seem to work as the first results are usually not relevant to the defined bounds (a country). I've seen a few apps working fine, so I'm wondering where the problem is. I came across the JQuery autocomplete plugin (http://code.google.com/p/geo-autocomplete/) which would seem like a good alternative since it has a region filter, but I'm unable to "install it" or use it because of my very limited knowledge (I learn by example). Could you please help me getting more relevant results with the above code or guide me through the implementation of the JQuery alternative? Of course I'm very open to other suggestions as well.

• Handle mysql restart in SQLAlchemy

  - by wRAR

  My Pylons app uses local MySQL server via SQLAlchemy and python-MySQLdb. When the server is restarted, open pooled connections are apparently closed, but the application doesn't know about this and apparently when it tries to use such connection it receives "MySQL server has gone away": File '/usr/lib/pymodules/python2.6/sqlalchemy/engine/default.py', line 277 in do_execute cursor.execute(statement, parameters) File '/usr/lib/pymodules/python2.6/MySQLdb/cursors.py', line 166 in execute self.errorhandler(self, exc, value) File '/usr/lib/pymodules/python2.6/MySQLdb/connections.py', line 35 in defaulterrorhandler raise errorclass, errorvalue OperationalError: (OperationalError) (2006, 'MySQL server has gone away') This exception is not caught anywhere so it bubbles up to the user. If I should handle this exception somewhere in my code, please show the place for such code in a Pylons WSGI app. Or maybe there is a solution in SA itself?

• Set bold rows in a QTreeView

  - by taynaron

  I have a custom subclass of a QTreeView in a pyqt application. I'm trying to give the user the ability to highlight and "lowlight" (for lack of a better term) rows. Highlighted rows should have bold text and (optionally) a different background color. Any ideas? I'm considering StyleSheets as an option, but have so far been unable to get that to work. If I set the QTreeView's stylesheet: self.setStyleSheet("QTreeView::item:selected {border: 1px solid #567dbc;}") I can't figure out how to manually enable 'states' that would keep only the desired rows at a particular state. If I try setting an individual item's stylesheet: #modelIndex is a valid QModelIndex modelIndex.internalPointer().setStyleSheet() I get a segfault. I'm not convinced stylesheets are the way to go, I'm open to all ideas. Thanks!

• How to read a file byte by byte in Python and how to print a bytelist as a binary?

  - by zaplec

  Hi, I'm trying to read a file byte by byte, but I'm not sure how to do that. I'm trying to do it like that: file = open(filename, 'rb') while 1: byte = file.read(8) # Do something... So does that make the variable byte to contain 8 next bits at the beginning of every loop? It doesn't matter what those bytes really are. The only thing that matters is that I need to read a file in 8-bit stacks. EDIT: Also I collect those bytes in a list and I would like to print them so that they don't print out as ASCII characters, but as raw bytes i.e. when I print that bytelist it gives the result as ['10010101', '00011100', .... ]

• Setup program needs framework 4.0 - But it's already installed

  - by Willem

  Hi all, I created a service which I now want to install to test. When running the setup program it prompts me to download and install .net fw 4.0, but I already have it installed. I did try to just install the file that I get pointed to (4.0 cliet), but not only does it still not work, it causes vs2010 to throw an unknown error and can't open. I've now uninstalled everything and started afresh with VS2010, framework 4.0 and win 7 but it still prompts me to install fw 4.0 when I try to run the setup. Can anyone please point me in the right direction? Thanx in advance Willem

• COM interop, Office 2010 x64 and Visual Studio 2010.

  Hi, I just installed Offic 2010 x64 on my Windows 7 x64 laptop. It already had Visual Studio 2010 on it. Now I try to add Microsoft.Office.Interop.Excel or something to the project, but it just can't find the project. When I try to open a project from the website of Microsoft (a sample of Office development) Visual Studio says that that kind of project is not supported. How is this possible? Is it a problem that I installed x64 of Office? Or is the problem Visual Studio 2010? Thanks

• Office Interop addins installer?

  - by jimbojw

  I have three C# Solutions in Visual Stuido 2008, one each for Word, Excel and PowerPoint using interop to hook various events. In each Solution, I have exactly one class, the one created by default when using File - New - Project - Visual C# - Office - 2007. Now that I have my addins working properly, it's time to create an installer. I understand that I may also have to distribute the PIAs. I would like my installer to register itself such that it can be uninstalled via the normal Add/Remove Programs mechanism. My organization is somewhat standardized around WiX for creating installers, but I'm open to any suggestions. How do I produce an MSI or EXE capable of installing my addins? GUI/wizard for the installer is not necessary. I'm happy to RTFM - so far all the tutorials I've found only explain how to create the project and do some of the coding. Maybe I'm using the wrong search terms? Thanks in advance for any help!

• Guaranteed COM object release?

Do I need to release workbook and sheet separately? I want to have Excel around for the lifetime of the program, it's a huge performance improvement.
