• Auto-fill the current date if the previous row was empty

  - by replax

  I have a spreadsheet sorted by dates. Everyday, I enter new data into it. After each day, I leave one row empty before starting the next day. Example: 20.09.12 XXXXX XXXXX XXXXX XXXX XXXXX XXXX XXXXX XX XX XXXXX XX XXXX 21.09.12 XXX XXXXX XXX XXXX X XXXX XXXX XXX 22.09.12 XXXX XX XXXX XXXX So I want excel to always fill in the current date whenever I enter data after one blank row, but obviously the dates shall stay the same - not be updated to the current date whenever I open excel. I am using Excel 2007 and while non vba ideas are preferred, vba is not a problem either!

• How to batch retrieve documents with mongoDB?

  - by edude05

  Hello everyone, I have an application that queries data from a mongoDB using the mongoDB C# driver something like this: public void main() { foreach (int i in listOfKey) { list.add(getObjectfromDB(i); } } public myObject getObjFromDb(int primaryKey) { document query = new document(); query["primKey"] = primaryKey; document result= mongo["myDatabase"]["myCollection"].findOne(query); return parseObject(result); } On my local (development) machine to get 100 object this way takes less than a second. However, I recently moved the database to a server on the internet, and this query takes about 30 seconds to execute for the same number of object. Furthermore, looking at the mongoDB log, it seems to open about 8-10 connections to the DB to perform this query. So what I'd like to do is have the query the database for an array of primaryKeys and get them all back at once, then do the parsing in a loop afterwards, using one connection if possible. How could I optimize my query to do so? Thanks, --Michael

• Regular Expression: Allow letters, numbers, and spaces (with at least one letter or number)

  - by makeee

  I'm currently using this regex ^[A-Z0-9 _]*$ to accept letters, numbers, spaces and underscores. I need to modify it to require at least one number or letter somewhere in the string. Any help would be appreciated! This would be for validating usernames for my website. I'd actually like to support as many characters as I can, but just want to ensure that I prevent code injection and that characters will display fine for all users. So I'm definately open to regex validation suggestions that would support a wider set of characters.

  - by user1684082

My procedure was: First python manage.py startapp black I added in project/settings.py under INSTALLED_APPS 'black', I added in project/urls.py url(r'^test/', include('black.urls')), Content of black/urls.py is: from django.conf.urls import patterns, url from black import views urlpatterns = patterns('', url(r'^$', views.index, name='index') ) And content of black/views.py: from django.http import HttpResponse def index(request): return HttpResponse("SHOW ME: BLACK") After all i synced the database.

• How to convert Beautiful Soup Unicode into a decimal value?

  - by MikeTheCoder

  I'm trying to Use python's Beautiful Soup Library to grab a bunch of divs from an html file, and from there get the string - which is a money value - that's inside the div. Then remove the dollar sign and convert it to a decimal so that I can use a greater than and less than conditional statement to compare values. I have googled the heck out of it and can't seem to come up with a way to convert this unicode string into a decimal value. I really could use some help here. How do I convert unicode into a decimal value? This was my last attempt: import unicodedata from bs4 import BeautifulSoup soup = BeautifulSoup(open("/Users/sm/Documents/python/htmldemo.html")) for tag in soup.findAll("div",attrs={"itemprop":"price"}) : val = tag.string new_val = val[8:] workable = int(new_val) if workable > 250: print(type(workable)) else: print(type(workable)) Edit: When I print the type of new_val I get : print(type(new_val))

• InfoPath Getting SharePoint Group Information

  - by anon

  I have an InfoPath form embedded in an aspx page on a SharePoint site. How do I bind the SharePoint user groups to a drop-down list on my form? What I've tried so far is to create a data connection to a web service (method GetGroupCollectionFromWeb) to pull the data. Next, I open the list box properties, select "Look up values from an external data source", select the data source, assign the entries, and I get the following error: "You must select a repeating group or field." What I don't understand is that since the method I am calling is called GetGroupCollectionFromWeb, isn't the return value a collection? And aren't collections repeating by definition? What am I missing, and is there a workaround? Thank you.

• Starting a browser from a textbox via Intent - Is http:// required?

  - by VitalyB

  Hi, I have the following code: /** Open a browser on the URL specified in the text box */ private void openBrowser() { Uri uri = Uri.parse(urlText.getText().toString()); Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent); } When I input "http://www.google.com" to the textbox, it works fine. However, when I try something like "www.google.com" it crashes with: No Activity found to handle Intent { act=android.intent.action.VIEW dat=www.google.com } Am I using Uri wrong? Is there a way to extract full address from it? Or am I supposed to write code that adds http manually? e.g, if not starts with http://, add http://. Thanks!

• Where are the best locations to write an error log in Windows?

  - by Keith Sirmons

  Where would you write an error log file, say ErrorLog.txt, in Windows? Keep in mind the path would need to be open to basic users for file write permissions. I know the eventlog is a possible location for writing errors, but does it work for "user" level permissions? EDIT: I am targeting Windows 2003, but I was posing the question in such a way as to have a "General Guideline" for where to write error logs. As for the EventLog, I have had issues before in an ASP.NET application where I wanted to log to the Windows event log, but I had security issues causing me heartache. (I do not recall the issues I had, but remember having them.)

• Is 'donation' considered as commerical?

  - by Horace Ho

  I want to port an open source program to iPhone, the license prohibited any commercial use of the code. I emailed the author and he sent back an email saying freeware is ok. Of course I cannot (should not) charge anything on top of the code. Still, I want to get compensation for my work on UI design, graphics and integration work. So I wonder: Is donation (via PayPal) OK for my case? Is in-app purchase OK? i.e. the program is free, the user has the option to buy addition theme graphics? Thanks

• How do I escape a string for a shell command in nodejs (V8 Javascript engine)?

  - by Maciek

  In nodejs, the only way to execute external commands is via sys.exec(cmd). I'd like to call an external command and give it data via stdin. In nodejs there does yet not appear to be a way to open a command and then push data to it (only to exec and receive its standard+error outputs), so it appears the only way I've got to do this right now is via a single string command such as: var dangerStr = "bad stuff here"; sys.exec("echo '" + dangerStr + "' | somecommand"); Most answers to questions like this have focused on either regex which doesn't work for me in nodejs (which uses Google's V8 Javascript engine) or native features from other languages like Python. I'd like to escape dangerStr so that it's safe to compose an exec string like the one above. If it helps, dangerStr will contain JSON data.

• JDOQL Any way to avoid multiple .contains() calls in the query when searching for the presence of on

  - by Finbarr

  The question pretty much says it all. If I have a class Class A public class A { ... private List<String> keys; ... } And I want to select all A instances from the DataStore that have atleast one of a List of keys, is there a better way of doing it than this: query = pm.newQuery(A.class); query.setFilter("keys.contains(:key1) || keys.contains(:key2) || keys.contains(:key3)"); List<A> results = (List<A>)query.execute(key1, key2, key3); This has not yet been implemented, so I am open to radical suggestions.

• Python BeautifulSoup Print Info in CSV

  - by Codin

  I can print the information I am pulling from a site with no problem. But when I try to place the street names in one column and the zipcodes into another column into a CSV file that is when I run into problems. All I get in the CSV is the two column names and every thing in its own column across the page. Here is my code. Also I am using Python 2.7.5 and Beautiful soup 4 from bs4 import BeautifulSoup import csv import urllib2 url="http://www.conakat.com/states/ohio/cities/defiance/road_maps/" page=urllib2.urlopen(url) soup = BeautifulSoup(page.read()) f = csv.writer(open("Defiance Steets1.csv", "w")) f.writerow(["Name", "ZipCodes"]) # Write column headers as the first line links = soup.find_all(['i','a']) for link in links: names = link.contents[0] print unicode(names) f.writerow(names)

• wxPython - wx.ChildFrame

  - by Dunwitch

  I'm sure this is simple, but I can't seem to find the answer. While using wx.MDIParentFrame, I open a new window with wx.MDIChildFrame. There is static text on the ParentFrame, and once the ChildFrame opens the text gets erased from the ParentFrame? import wx class Frame(wx.MDIParentFrame): def __init__(self): wx.MDIParentFrame.__init__(self, None, -1, "Main Window", size=(800,600), style=wx.DEFAULT_FRAME_STYLE | wx.FRAME_NO_WINDOW_MENU) menu = wx.Menu() menu.Append(100, "&New Window") menu.Append(101, "E&xit") menubar = wx.MenuBar() menubar.Append(menu, "&File") self.SetMenuBar(menubar) self.Bind(wx.EVT_MENU, self.OnNewWindow, id=100) self.Bind(wx.EVT_MENU, self.OnExit, id=101) self.Center() background_text = wx.StaticText(self, id=-1, label="This is background text", pos = (20, 250)) def OnExit(self, evt): self.Close(True) self.Destroy() def OnNewWindow(self, evt): win = wx.MDIChildFrame(self, -1, "Child Window", size = (300, 300), style=wx.DEFAULT_FRAME_STYLE ^ (wx.MAXIMIZE_BOX | wx.RESIZE_BORDER)) win.SetBackgroundColour("#BB00e0") win.Show(True) if __name__ == '__main__': app = wx.PySimpleApp() frame = Frame() frame.Show() app.MainLoop()

• Advanced text search in actionscript-return ALL nouns,adjectives and verbs..

  - by eco_bach

  Hi I know that as3 has some powerful new text search capabilities, especially when combined with regex. I don't even know if this is possible, but I would like to somehow, search any block of text, and return all nouns, adjectives and verbs. What would be the best(most efficent) way to do this? Is regex an option? or would I have to load in some sort of open sourced dictionary 9as used in spellcheckers) to compare with or?? After, I've pulled all the nouns, adjectives and verbs, I need to count and prioritize by their frequency. Any suggestions welcome...

• How to get ListView to grow to the size of content

  - by Jared

  So I have a fairly complex activity the parent being a linearlayout with a table with some basic info and buttons. Then a couple listviews that the user can add items to. So these listviews grow more and more as the user uses the app. The problem I'm running into is the Linearlayout is bigger then the resolution of the screen and so it needs to scroll. So the scrolling doesn't work on the Listviews. I've tried playing with changing the layout_height of the listview and its child element with no success. Is there a way to make these couple listviews expand out to the amount of children? Or am I going about this all wrong? If so what other controls can I use? I'm open to any ideas. I really just don't know how to go about this. Thanks

• How to quantify your "slow" development machine?

  - by lance

  ( Please provide the question this one duplicates. I'm disappointed I couldn't find it. ) My development machine is "slow". I wait on it "a lot". I've been asked by decision makers who want to help to fairly and accurately measure that time. How do you quantify the amount of time you spend waiting on the computer (during compiles, waiting for apps to open every day, etc). Is there software which effectively reports on this sort of thing? Is there an OS metric (I/O something something, pagefile swapping frequency, etc, etc) that captures and communicates this particularly well? Some sort of benchmark you'd recommend me testing against?

• Redirect window of command line tool to your app (Windows)

  - by dribler

  Hello, is there a way (on Windows XP+) to redirect the output of a window created by a process created with e.g. CreateProcess to a window of your own program? I'd like to make a nicer GUI for ffplay.exe which is an open source video player. It is a command line tool, which opens a simple window in which it plays back the video. Can I "capture" this window and display the output in my own program somehow? Thanks for any hints you can provide.

• Synchronous HTTP Client with .NET sockets

  - by Ray Wits

  Does anyone know of any open source C# projects or some sample code that implement a synchronous HTTP client using sockets? I'm working on a project where I need a HTTP client using sockets. It can't use WebRequest or WebClient, nor can it use Asynchronous sockets. Don't ask. Also it would ideally be on .NET 2.0, yeah very cutting edge here. I figured the web would have tons of samples for this but suprisingly I couldn't find any. Probably because everyone is fortunate enough to use the built in APIs. If I don't find something I'll have to write it myself, which I don't really want to have to reinvent that wheel.

• Linux server, locating files containing nothing but 4 specific lines.

  - by Denis

  Hi, I'm dealing with a compromised website, in which hackers injected an htaccess instruction to redirect traffic. I can easily locate .htaccess files that contain the forwarding hack, BUT in cases where the directory already contained an htaccess file, they appended the dangerous instructions, so I cannot just deleted any htaccess file or could harm the site by letting formerly pw-protected directories wide open, or urlrewrite instructions (WordPress) be deleted, etc. I could not find the way to locate files that only contain those 4 lines of redirect hack, could you shed some light ? So far, using find . -type f -exec grep -q targetpiratedomain {} \; -exec echo rm {} \; Thanks !

• Which Java MVC frameworks integrate easily with StringTemplate?

  - by Daniel Jomphe

  It's hard to see how StringTemplate integrates easily (or not) with popular Java web MVC frameworks. Which Java MVC frameworks integrate easily with StringTemplate? A good answer: mentions one solution to integrate with a framework, includes a link to something useful and applicable, like: a tutorial, or documentation, or a reference to source code: free, and open source or public domain. Readers/Voters, please vote for a solution if you know it's true and great. In the scope of this question, I am not interested in any other templating engine than StringTemplate.

• Passing input to Ant's <exec> task

  - by mikek

  I have an Ant script running a standard -task after taking in an inputed password: <input message="Password:" addproperty="password"> <handler classname="org.apache.tools.ant.input.SecureInputHandler" /> </input> <exec executable="/bin/sh" input="${password}" failonerror="true"> <arg line='-c "myScript.sh"' /> </exec> The script myScript.sh prompts the user for a password, and, it was my understanding that from the Ant documentation that input is supposed relay input into whatever the <exec> task is executing, but instead I get (for entering the password foobar) [exec] Failed to open /usr/local/foobar which is followed by a stack trace from my script complaining about an incorrect password...so obviously I've understood the documentation wrong. Does anybody know how to handle prompted input from external scripts in Ant?
