  • Is there a way of getting a file name and inserting into Matlab script?

    - by torr
    In a folder, I have both my .m file that contains the script and an imaging .dcm file that needs to be analyzed. Folder structure: Folder1/analysis.m Folder1/meas_dynamic_123.dcm My script (analysis.m) begins as follows: target =''; <== here should go the full path to the file + filename example: /Volumes/Data/Folder1/meas_dynamic_123.m txt = dir(target); // etc So I'm wondering if there is a way of when running analysis.m it will: automatically search the folder it's in, grab the full path + filename of file containing string dynamic in the name, insert its full path + name into target variable continue running the script Does anyone have any pointers on how to achieve this? Using ffpath?

  • is there a way to use cin.getline() without having to define a char array size before hand?

    - by zebraman
    Basically my task is having to sort a bunch of strings of variable length ignoring case. I understand there is a function strcasecmp() that compares cstrings, but doesn't work on strings. Right now I'm using getline() for strings so I can just read in the strings one line at a time. I add these to a vector of strings, then convert to cstrings for each call of strcasecmp(). Instead of having to convert each string to a cstring before comparing with strcasecmp(), I was wondering if there was a way I could use cin.getline() for cstrings without having a predefined char array size. Or, would the best solution be to just read in string, convert to cstring, store in vector, then sort?

  • Selecting an option with javascript

    - by Fibericon
    I have a drop down menu that I want to have selected on page load. This is what I'm using at the moment: var selector = document.getElementById("action_person").firstChild; var n = 0; while(selector.options[n] != null) { if(selector.options[n].value == "person") { selector.options.selectedIndex = n; } n++; } I've also tried replacing selector.options.selectedIndex = n with selector.options[n].selected = true. However, it never selects for me. It always shows the item at the top of the drop down. I've verified that the value "person" does exist in the drop down, and that the variable "selector" does point to a valid drop down. What am I doing wrong here?

  • Multiple connections to a MySQL database in a single PHP script.

    - by st3
    There are multiple times in one page where I need to connect and subsequently query a MySQL database, yet my code won't let me. I think it might be something to do with how my files are nested but it makes no sense. I am opening the SQL connection in the header file. The top of the offending page looks like the following: <?php $page_title = 'Dashboard'; include('templates/header.inc'); // includes a 'require_once('mysqli_connect.php') and a small query to the database; require_once('includes/functions.php'); require_once('includes/dashboard_sql.php'); // Contains functions which connect to database (which are failing.) ?> I get the PHP error Notice: Undefined variable: dbc in /Library/WebServer/Documents/pediatory_site/includes/dashboard_sql.php Where $dbc is the database connection defined in mysqli_connect.php. If anyone could help me out that would be great.

  • Struts 1 - problem in showing ActionMessages through a JSP page

    - by Yatendra Goel
    I am using Struts 1.3.10. I am trying to display ActionMessage and ActionError set by Action class through a JSP page. The problem is that the ActionErrors are displaying well but ActionMessages are not displaying. When I debug the application, I found that the messages (reference variable of ActionMessages) contains messages. I also saved those messages through saveMessages(request, messages) method of Action class. So, I think that the problem is in the JSP code through which I am trying to display those messages. The JSP code is as follows: <logic:messagesPresent> <ul id="messsages"> <html:messages id="msg" message="true"> <li><bean:write name="msg"/> </li> </html:messages> </ul> </logic:messagesPresent>

  • Number range for color in GLSL

    - by kotoko
    I'm figuring out how to set a colour in a Fragment Shader. This statement gl_FragColor = (0.1,0.6,1,1); gives me white regardless of what I enter in the first 3 values. I was expecting to either give it values between 0 and 255 or 0 and 1 but neither seems to work. I can change how bright it is with values from 0 to 1 in the fourth value, but nothing for colour. Can anybody tell me if: gl_FragColor is the right variable to set. What is the range of values for the first three values. What am I currently making the Shader do.

    - by tkoomzaaskz
    I've got a script with a variable taken from command line parameters. I want to check if it's value is one of dev, beta or prod.

What is wrong in my script?

  • NoneType has no attribute Append

    - by Rosarch
    I'm new to Python. I can't understand why a variable is None at a certain point in my code: class UsersInRoom(webapp.RequestHandler): def get(self): room_id = self.request.get("room_id") username = self.request.get("username") UserInRoom_entities = UserInRoom.gql("WHERE room = :1", room_id).get() if UserInRoom_entities: for user_in_room in UserInRoom_entities: if user_in_room.username == username: user_in_room.put() # last_poll auto updates to now whenenever user_in_room is saved else: user_in_room = UserInRoom() user_in_room.username = username user_in_room.put() UserInRoom_entities = [] UserInRoom_entities.append(user_in_room) // error here # name is `user_at_room` intead of `user_in_room` to avoid confusion usernames = [user_at_room.username for user_at_room in UserInRoom_entities] self.response.out.write(json.dumps(usernames)) The error is: Traceback (most recent call last): File "C:\Program Files\Google\google_appengine\google\appengine\ext\webapp\__init__.py", line 507, in __call__ handler.get(*groups) File "path\to\chat.py", line 160, in get AttributeError: 'NoneType' object has no attribute 'append' How is this possible? I'm setting UserInRoom_entities = [] immediately before that call. Or is something else the None in question?

  • Can I increase the scope of 'this' in the following example?

    - by Stomped
    In using a jquery callback, I found that 'this' isn't defined anymore. I've found a work around, which is to set 'this' to another variable. For example, like so: function handler(DATA) { myThis = this; $.post( 'file.php', DATA, function() { // THIS where I need access to 'this', but its not available // unless I've used the 'myThis' trick above } ); } It works like this, but I am always looking for 'the right way' or 'the better way' to do things. Is this the best way? or is there another?

  • Return result of block passed to #scan during regex

    - by Oli
    I've searched and not been able to find the right way of doing what I'm trying to. I read a file line by line and want to create a new object from a regex on each line. I'm not using an XML parser because the data is not well formed and listed below is all I need to get from each line. I can't seem to get scan to return the result of the block. It just returns the original string. I have temporarily gotten around it by creating this temp variable, but I'm sure there is a better way. enum = File.foreach(filename) enum.map do |line| temp = nil line.scan(/<cab id="(\w+)" updates="(\d+)"/) { |a,b| temp = Cab.new(a,b) } temp end Thanks for any help.

  • Ruby: having callbacks on 'attr' objects

    - by JP
    Essentially I'm wondering how to place callbacks on objects in ruby, so that when an object is changed in anyway I can automatically trigger other changes: class MyClass attr_reader :proxy def proxy=(string_proxy = "") begin @proxy = URI.parse("http://"+((string_proxy.empty?) ? ENV['HTTP_PROXY'] : string_proxy)) @http = Net::HTTP::Proxy.new(@proxy.host,@proxy.port) rescue @http = Net::HTTP end end end m = MyClass.new m.proxy = "myproxy.com:8080" p m.proxy # => <URI: @host="myproxy.com" @port=8080> # However changing m.proxy will not change the @http variable, as proxy= is not being called. # Desired functionality: m.proxy = nil # Now @http.class is Net::HTTP, not Net::HTTP::Proxy

  • Wrong extraction of .attr("href") in IE7 vs all other browsers?

    - by EmKay
    Can it really be true that the attr("href") command for a link is handled very different in IE7 in comparison to all other browsers? Let's say I have a page at http://example.com/page.html and I have this HTML: <a href="#someAnchor" class="lnkTest">Link text</a> and this jQuery: var strHref = $(".lnkTest").attr("href"); Then in IE7 the value of the strHref variable will be "http://example.com/page.htm#someAnchor" but in other browsers it will be "#someAnchor". I believe that the last mentioned case is the most correct one, so is it just a case of IE7 being a bad boy or is it a bug in jQuery?

  • LINQ Queries And Context

    - by Soo
    Hello SO, I have a slight issue with some code I'm writing if(parameter == 1) { var linq = from a in db.table select a; } else { var linq = from a in db.table where a.id = 1 select a; } foreach(var b in linq) { ... } So basically what's going on is that the variable "linq" is different depending on the value of "parameter". When I try to loop through "linq" with my foreach loop, I get an error about how linq doesn't exist in the current context. What is the best way to work around this type of issue?

  • strtok program crashing.

    - by baskin
    Hi, the program for strtok given on http://www.opengroup.org/onlinepubs/000095399/functions/strtok.html crashes everytime.. #include <string.h> ... char *token; char *line = "LINE TO BE SEPARATED"; char *search = " "; /* Token will point to "LINE". */ token = strtok(line, search); /* Token will point to "TO". */ token = strtok(NULL, search); If I use a char array for variable 'line', it works. i.e. char line[] = "LINE TO BE SEPARATED" works. Kindly explain.

  • can't save form content to database, help plsss!!

    - by dana
    i'm trying to save 100 caracters form user in a 'microblog' minimal application. my code seems to not have any mystakes, but doesn't work. the mistake is in views.py, i can't save the foreign key to user table models.py looks like this: class NewManager(models.Manager): def create_post(self, post, username): new = self.model(post=post, created_by=username) new.save() return new class New(models.Model): post = models.CharField(max_length=120) date = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(User, blank=True) objects = NewManager() class NewForm(ModelForm): class Meta: model = New fields = ['post'] # widgets = {'post': Textarea(attrs={'cols': 80, 'rows': 20}) def save_new(request): if request.method == 'POST': created_by = User.objects.get(created_by = user) date = request.POST.get('date', '') post = request.POST.get('post', '') new_obj = New(post=post, date=date, created_by=created_by) new_obj.save() return HttpResponseRedirect('/') else: form = NewForm() return render_to_response('news/new_form.html', {'form': form},context_instance=RequestContext(request)) i didn't mention imports here - they're done right, anyway. my mistake is in views.py, when i try to save it says: local variable 'created_by' referenced before assignment it i put created_py as a parameter, the save needs more parameters... it is really weird help please!!

  • BATCH - wait for executable to finish before starting next result

    - by user3697573
    I'm pretty much a noob at this, so any help is appreciated. I'm trying to run the video transcoding executable REDline on all .R3D files in a given folder. REDline only accepts single files, which is the issue. I finally got it to search recursively for the files I need, but my problem is the search function passes the next result to REDline before the first one is finished transcoding. I have the search results that need to run in a variable inside REDline. Here's the code: for /r D:\folder\ %%a in (*) do ( "C:/Program Files/REDCINE-X PRO 64-bit/REDLine.exe" --exportPreset "Prores_Intermediate" --i "%%~dpnxa" --useRSX 2 --masterRMDFolder "" -s 0 -e 95 ) After about .7 seconds, REDline reports 'received stop message from client'. I don't think this is a REDline error, as I have been able to transcode single files successfully. Thanks.

  • setTimeout is acting weird

    - by mnish
    I am trying to make a simple setTimeout, to make a div tag invisible after 2 seconds. The setTimeout function makes the div invisible but irregularly, sometimes immediately and sometimes after 1 sec, and so on. Here is my code: function beginTimeOut(){ t = setTimeout(function(){hideSubMenu()},2000); } function hideSubMenu(){ var elem; elem = document.getElementById("ul_navlist1"); elem.style.visibility="hidden"; clearTimeout(t); } By the way, t is a global variable. I have tried this too: t = setTimeout("hideSubMenu()",2000); but with the same irregular results.

  • Can you simulate a boolean flag in XSLT?

    - by R.C.
    Hey guys, I'd like to simulate a flag in an xslt script. The idea is for template foo to set a flag (or a counter variable, or anything), so that it can be accessed from template bar. Bar isn't called from foo, but from a common parent template (otherwise I would pass a parameter to it). The structure is like this: <xsl:template match="bla"> <xsl:apply-templates select="foo"/> <!-- depending on the contents of foo... --> <xsl:apply-templates select="bar"/> <!-- ... different things should happen in bar --> </xsl:template> Any tricks are much appreciated.

  • c++ Array passing dilemma

    - by Thomas
    Hi, I am writing a function that takes a string, string pointer and an int. The function splits the string based on a set of rules and puts each token into an array. I need to return the array out of the function with the number of elements in the int variable etc. I am stuck as to how I return the array as I can not use auto other wise it is destroyed and I am reluctant to use new as I feel this is patchy. I have other ideas on how to go about this but would like to see how other people go about this first. I could also be wrong and it could be possible to pass an auto out of an array. I can also not use vectors so there goes a copy constructor.

  • result set using two different views (from an if statement)

    Hi All, I have a bit of code that works with a result set called "result" (original I know) but depending on the incoming variable I'd like to fire the specific query depending. I have the below in an if statement but that just makes the "result" recordset gets those nasty red lines and it doesn't work.

  • Question About NerdDinner Controller Constructors

    - by Gavin Draper
    I've been looking at the Nerd Dinner app, more specifically how it handles its unit tests. The following constructors for the RSVPController are confusing my slightly public RSVPController() : this(new DinnerRepository()) { } public RSVPController(IDinnerRepository repository) { dinnerRepository = repository; } From what I can tell the second one is used by the unit tests so it can use Fake repositories. What I cant work out is what the first constructor does. It doesn't seem to ever set the dinnerRepository variable, it seems to imply its inheriting from something but I really don't get it. Can anyone explain? Thanks

  • Concatenating string with number in Javascript

    - by Sparky
    I'm trying to create a simple calculator in Javascript. I have an array named expression chunk[0] = 12 chunk[1] = + (the "+" sign) chunk[1] = 5 I used a for loop to loop through the chunks (chunk[]) and join then into a single expression as follows:- equation = ""; // To make var equation a string for(i = 0; i <= length; i++) { equation = equation + expression[i]; alert(expression[i]); } alert(equation); alert(expression[i]) showed values 12, + and 5. But alert(equation) showed 125 (instead of "12+5"). I need the variable equation to be "12+5" so that I can later call eval(equation) and get the value of 12+5. What am I doing wrong here?
