• Access to selection in gmail message body with Google Apps Script

  - by Mike Ellis

  Can app scripts access the current selection in a gmail message? I frequently compose messages that include engineering calculations and make use of the Google Calc feature do the calculation or convert to the desired units, e.g. 4000 Btu/hr * 8 hrs in kWh It would be really convenient to be able to select the above, hit a mapped key (e.g. Ctrl-K) and have the inserted after the expression 4000 Btu/hr * 8 hrs in kWh = 0.9378 kWh instead of having to paste the expression into a search box and then copy and paste the answer. I could certainly write a solution using a keymapper and a small python script to grab the current selection, send it to the gcalc api, etc ..., but my real motivation is to get familiar with Apps Scripts's capabilities and limitations. I suppose the uber-question here is "what kinds of user actions and state information can App Script access in Gmail messages (and/or Google docs) that are being edited?"

• Permanent remove of logo in Windows Scripting Host (WSH() scripts.

  - by antonio

  I know two ways to remove the logo permanently. The "official" one: cscript //Nologo //S Will save current command line options for current user. A ftype approach with admin privileges: ftype wsffile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype jsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype vbsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* Double-%'s are needed only if you use the lines in a batch file. The latter will all users via affect the reg key HKEY_CLASSES_ROOT\<file>\Shell\Open\Command, where <file> can be wsffile, jsfile or vbsfile. Do you know where are stored the cscript //Nologo //S settings?

• Database Modeling - Either/Or in Many-to-Many

  - by EkoostikMartin

  I have an either/or type of situation in a many-to-many relationship I'm trying to model. So I have these tables: Message ---- *MessageID MessageText Employee ---- *EmployeeID EmployeeName Team ---- *TeamID TeamName MessageTarget ---- MessageID EmployeeID (nullable) TeamID (nullable) So, a Message can have either a list of Employees, or a list of Teams as a MessageTarget. Is the MessageTarget table I have above the best way to implement this relationship? What constraints can I place on the MessageTarget effectively? How should I create a primary key on MessageTarget table?

• XCode Syntax Coloring Broken

  - by sw12345

  XCode frequently seems to lose it's mind, and doesn't color code system classes or provide correct "code sense" suggestions. This is endlessly frustrating. The question has been asked on at least three other occasions: http://stackoverflow.com/questions/2263994/problems-with-xcode-syntax-highlighting http://stackoverflow.com/questions/1627033/xcode-code-sense-color-completion-not-working http://stackoverflow.com/questions/2138047/xcode-code-loses-syntax-coloring I have switched by project version to/from 3.1-compatiable and 3.2-compatiable, completely restarting XCode before and after each change with no effect. I have rebuilt the code sense indexes and completely restarted XCode with no change. I have built my project to make sure there are no errors and restarted. I have copied my files (sans .svn files) to a different location - same problem. I've already completely disabled the argument "placeholders" because they screw up my documents when i type too fast... all I'm asking for is for the "esc" key to display the correct list of properties and methods.

• Castle Windsor: Inject NameValueCollection vs. Dictionary

  - by Aren B

  I've already done many configs where dictionaries are passed into services in the <parameters> block. But what I find myself needing right now is to build a NameValueCollection (allowing multiple entries with the same key) or a Collection of KeyValuePair objects. The reason for this is im not using this dictionary to look up b when given a, im basically using it to pass in a Tuple (pair) of (a,b) to be used later in code. Im kind of new to castle windor and I was wondering how i would go about making a List of KeyValuePair's injected, or a NameValueCollection injected.

• Using Python's ConfigParser to read a file without section name

  - by Arrieta

  Hello: I am using ConfigParser to read the runtime configuration of a script. I would like to have the flexibility of not providing a section name (there are scripts which are simple enough; they don't need a 'section'). ConfigParser will throw the NoSectionError exception, and will not accept the file. How can I make ConfigParser simply retrieve the (key, value) tuples of a config file without section names? For instance: key1=val1 key2:val2 I would rather not write to the config file.

• How to determine OS Platform with WMI?

  - by cary.wagner

  I am trying to figure out if there is a location in WMI that will return the OS Architecture (i.e. 32-bit or 64-bit) that will work across "all" versions of Windows. I thought I had figured it out looking at my Win2k8 system when I found the following: Win32_OperatingSystem / OSArchitecture I was wrong. It doesn't appear that this field exists on Win2k3 systems. Argh! So, is anyone aware of another field in WMI that "is" the same across server versions? If not, what about a registry key that is the same? I am using a tool that only allows me to configure simple field queries, so I cannot use a complex script to perform. Any help would be greatly appreciated! Cheers... Cary

• Tell The Program What To Do When No Save Data Is Found NSUserDefaults, iPhone

  - by Stumf

  Hello all, I have saved data which was saved using NSUserDefaults. I was under the impression that if there was nothing saved to the key already (first time app is run) it would default to 0. This however doesn't seem to be the case. Here is what I have: To save: - (void)viewWillDisappear:(BOOL)animated { [[NSUserDefaults standardUserDefaults] setInteger:setbatteryHealthCalculated forKey:@"healthValue"]; [[NSUserDefaults standardUserDefaults] synchronize]; } To load: - (void) viewWillAppear:(BOOL)animated { NSInteger setbatteryHealthCalculated = [[NSUserDefaults standardUserDefaults] integerForKey:@"healthValue"]; } To check for save value: - (IBAction)check{ NSInteger setbatteryHealthCalculated = [[NSUserDefaults standardUserDefaults] integerForKey:@"healthValue"]; if (setbatteryHealthCalculated = 0) { [self performSelector:@selector(displayAlert) withObject:nil]; }

• Best way to encrypt certain fiels in SQL Server 2008?

  - by Josh

  I'm writing a .net web app that will read and write information to a SQL 2008 backend database. Some of this information will be highly confidential in nature so I want to encrypt certain data elements. I dont want to use TDE or any full-database encryption for performance reasons. My main concern is protecting this sensitive data as a last resort against a SQL injection or even a database server compromise. My question is what is the best way to do this to preserve performance? Is it faster to use the SQL2008 encryption functions such as EncryptByKey, or would it be faster to encrypt and decrypt the data in the .NET web app itself using a symmetric key stored in the secure web.config and store the encrypted values in the DB?

• Storing member function pointers of derived classes in map

  - by Kiran Mohan

  Hello, I am trying to implement a factory for two classes Circle, Square both of which inherits from Shape. class Shape { public: virtual static Shape * getInstance() = 0; }; class Circle : public Shape { public: static const std::string type; Shape * getInstance() { return new Circle; } }; const std::string Circle::type = "Circle"; class Square : public Shape { public: static const std::string type; Shape * getInstance() { return new Square; } }; const std::string Square::type = "Square"; I want to now create a map with key as shape type (string) and value as a function pointer to getInstance() of the corresponding derived class. Is it possible? Thanks, Kiran

• php, mySQL - how to create a table?

  - by user296516

  Hi guys, I have written a code that should check weather there is a table called imei.$addimei and, if not, create it... $userdatabase = mysqli_connect('localhost', 'root', 'marina', 'imei'); ... $result = mysqli_query($userdatabase, "SELECT * FROM imei".$addimei."" ); if ( !$result ) { echo('creating table...'); /// if no such table, make one! mysql_query ( $userdatabase, 'CREATE TABLE imei'.$addimei.'( ID int NOT NULL AUTO_INCREMENT, PRIMARY KEY(ID), EVENT varchar(15), TIME varchar(25), FLD1 varchar(35), FLD2 varchar(35), IP varchar(25), )' ); } Yet the CREATE TABLE somehow doesn't seem to work. Warning: mysql_query() expects parameter 1 to be string, object given in C:\xampp\xampp\htdocs\mobi\mainmenu.php on line 564 Any idea's what wrong? Thanks!

• Databases design - one link table or multiple link tables?

  - by David

  Hi there, I'm working on a front end for a database where each table essentially has a many to many relationship with all other tables. I'm not a DB admin, just a few basic DB courses. The typical solution in this case, as I understand it, would be multiple link tables to join each 'real' table. Here's what I'm proposing instead: one link table that has foreign key dependencies to all other PKs of the other tables. Is there any reason this could turn out badly in terms of scalability, flexibility, etc down the road?

• Converting HTML special characters into their value using Python

  - by tipu

  I have a file that's littered with these: http://www.utexas.edu/learn/html/spchar.html That link just displays all sorts of HTML entities, such as – &ndash; — &mdash; ¡ &iexcl; and so on. Is it possible in Python to natively convert these characters back into their values so any occurrences of &ndash; will appear as – instead? My current approach was just to make a dict of key html entities and their utf-8 values and do search and replace, but I was wondering if there are any libraries that can take care of this for me.

• Rabbitmq queue sharding

  - by kolchanov

  I have to implement this scenario: An external application publish message to rabbitmq. This message has a client_id property. We can place this id to routing key or message header or some other property. I have to implement sharding in a exchange routng logic - the message should be delivered to specific queue based on the client_id range. Is it possible to implement in a standard exchanges? If not what exchange should I take as the base? How to dynamicly change client_id ranges?

• What stage of normalization is this? (moving repeating data into separate table)

  - by Sergio

  Hi There, I have noticed that when designing a database I tend to shift any repeating sets of data into a separate table. For example, say I had a table of people, with each person living in a state. I would then move these repeating states into a separate table and reference them with foreign keys. However, what if I was not storing any more data about states. I would then have a table with StateID and State in. Is this action correct? State is dependant on the primary key of the users table, so does shifting it into its own table help with anything? Thanks,

• What's the best way to count unique visitors with Hadoop?

  - by beagleguy

  hey all, just getting started on hadoop and curious what the best way in mapreduce would be to count unique visitors if your logfiles looked like this... DATE siteID action username 05-05-2010 siteA pageview jim 05-05-2010 siteB pageview tom 05-05-2010 siteA pageview jim 05-05-2010 siteB pageview bob 05-05-2010 siteA pageview mike and for each site you wanted to find out the unique visitors for each site? I was thinking the mapper would emit siteID \t username and the reducer would keep a set() of the unique usersnames per key and then emit the length of that set. However that would be potentially storing millions of usernames in memory which doesn't seem right. Anyone have a better way? I'm using python streaming by the way thanks

  In my applications we.config file I have a connection string stored. I encrypted it using '---open the web.config file Dim config As Configuration = _ ConfigurationManager.OpenWebConfiguration( _ Request.ApplicationPath) '---indicate the section to protect Dim section As ConfigurationSection = _ config.Sections("connectionStrings") '---specify the protection provider section.SectionInformation.ProtectSection(protectionProvider) '---Apple the protection and update config.Save() Now I can decrypt it using the code Dim config As Configuration = _ ConfigurationManager.OpenWebConfiguration( _ Request.ApplicationPath) Dim section As ConfigurationSection = _ config.Sections("connectionStrings") section.SectionInformation.UnProtectSection() config.Save() I want to know where is the key stored. Also If somehow my web.config file is stolen, will it be possible for him/her to decrypt it using thhe code above.

• Sort by an object's type

  - by Richard Levasseur

  Hi all, I have code that statically registers (type, handler_function) pairs at module load time, resulting in a dict like this: HANDLERS = { str: HandleStr, int: HandleInt, ParentClass: HandleCustomParent, ChildClass: HandleCustomChild } def HandleObject(obj): for data_type in sorted(HANDLERS.keys(), ???): if isinstance(obj, data_type): HANDLERS[data_type](obj) Where ChildClass inherits from ParentClass. The problem is that, since its a dict, the order isn't defined - but how do I introspect type objects to figure out a sort key? The resulting order should be child classes follow by super classes (most specific types first). E.g. str comes before basestring, and ChildClass comes before ParentClass. If types are unrelated, it doesn't matter where they go relative to each other.

• Lose changed data in session

  - by user150528

  Our asp.net 2.0 application has a very long process (synchronized) before sending response back to client. I observed that a second request, exactly same the initial one, was sent after client IE8 waited response for a long period of time while our application was still processing the first request. I use page session with predefined key to store a flag when the initial request arrives and then starts long process while client IE waits for the response, so if second request comes in, our application checks the session value. After our application sets the session flag and starts processing, I use Fiddler “Abort Session” to abort the initial request, right away the second request (same as the first one) is sent automatically, but session value set earlier seems no longer exist. Any thoughts?

• Custom certificate as proof of transaction

  - by Andy

  I'm developing a site where a user conducts a given transaction and once completed, the user is issued with a 'secure certificate'. The certificate serves as proof of the transaction and the user is able to upload the certificate at a later stage, to view the details of the transaction. At the moment I'm using a custom XML document with encrypted fields. It works perfect, but I would like a standardized approach, such as an X.509 certificate. I'm no encryption expert, but from what I gather, X.509 is more geared towards SSL issued by a CA. Is it possible to create your own valid valid CRT file? As a test, I created a CRT file with the example provided on WikiPedia. However, when I open the file in Windows I get this warning: Invalid Public Key Security Object File - This file is invalid as the following: Security Certificate. Not having much luck here, so time to ask the experts. What direction should I be heading in? Any guidance would be greatly appreciated.

• How do I find hash value of a 3D vector ?

  - by brainydexter

  I am trying to perform broad-phase collision detection with a fixed-grid size approach. Thus, for each entity's position: (x,y,z) (each of type float), I need to find which cell does the entity lie in. I then intend to store all the cells in a hash-table and then iterate through to report (if any) collisions. So, here is what I am doing: Grid-cell's position: (int type) (Gx, Gy, Gz) = (x / M, y / M, z / M) where M is the size of the grid. Once, I have a cell, I'd like to add it to a hash-table with its key being a unique hash based on (Gx, Gy, Gz) and the value being the cell itself. Now, I cannot think of a good hash function and I need some help with that. Can someone please suggest me a good hash function? Thanks

• LRU caches in C

  - by lazyconfabulator

  I need to cache a large (but variable) number of smallish (1 kilobyte to 10 megabytes) files in memory, for a C application (in a *nix environment). Since I don't want to eat all my memory, I'd like to set hard memory limit (say, 64 megabytes) and push files into a hash table with the file name as the key and dispose of the entries with the least use. What I believe I need is an LRU cache. Really, I'd rather not roll my own so if someone knows where I can find a workable library, please point the way? Failing that, can someone provide a simple example of an LRU cache in C? Related posts indicated that a hash table with a doubly-linked list, but I'm not even clear on how a doubly-linked list keeps LRU. Side note: I realize this is almost exactly the function of memcache, but it's not an option for me. I also took a look at the source hoping to enlighten myself on LRU caching, with no success.

• How do you sort files numerically?

  - by Zachary Young

  Hello all, First off, I'm posting this because when I was looking for a solution to the problem below, I could not find one on stackoverflow. So, I'm hoping to add a little bit to the knowledge base here. I need to process some files in a directory and need the files to be sorted numerically. I found some examples on sorting--specifically with using the lamba pattern--at wiki.python.org, and I put this together: #!env/python import re tiffFiles = """ayurveda_1.tif ayurveda_11.tif ayurveda_13.tif ayurveda_2.tif ayurveda_20.tif ayurveda_22.tif""".split('\n') numPattern = re.compile('_(\d{1,2})\.', re.IGNORECASE) tiffFiles.sort(cmp, key=lambda tFile: int(numPattern.search(tFile).group(1))) print tiffFiles I'm still rather new to Python and would like to ask the community if there are any improvements that can be made to this: shortening the code up (removing lambda), performance, style/readability? Thank you, Zachary

• Access event.target in IE8 unobstrusive Javascript

  - by Mirko

  The following function gets the target element in a dropdown menu: function getTarget(evt){ var targetElement = null; //if it is a standard browser if (typeof evt.target != 'undefined'){ targetElement = evt.target; } //otherwise it is IE then adapt syntax else{ targetElement = evt.srcElement; } //return id of element when hovering over or if (targetElement.nodeName.toLowerCase() == 'li'){ return targetElement; } else if (targetElement.parentNode.nodeName.toLowerCase() == 'li'){ return targetElement.parentNode; } else{ return targetElement; } Needless to say, it works in Firefox, Chrome, Safari and Opera but it does not in IE8 (and I guess in previous versions as well). When I try to debug it with IE8 I get the error "Member not Found" on the line: targetElement = evt.srcElement; along with other subsequent errors, but I think this is the key line. Any help will be appreciated.
