• Python programming. Accessing Windows rigth click menu options

  - by Zack

  I'm hoping to automate a few tasks at work. One of them being combining and converting power point files to PDFs. I'm a bit of a newbie (I just finished Magus Heitland's Beginning Python), so I'm not entirely sure what I'm specifically asking. On windows, one can select multiple files, right click, and select combine as adobe PDF. I've figured out the 'grouping' of the files I want to convert (I traverse the dir and nest the files inside of a list based on their names), but I'm unsure how to pursue the next step (the rightclick/combine command). Googling has led me to things like win32api, pywinauto, and ctypes. But as I read over what they do my newbieness prevents me from knowing which is the tool I need. Could any one suggest a few good resources or tips?

• "Intercepting" user input into text box and removing it

  - by James P

  I have a text box that I would like to do some validation on. At the moment I have this code: function updateChanger() { // Validate input var likeMessage = validateInput($("#like").val()); alert(likeMessage); } function validateInput(input) { input = input.replace(/[^a-zA-Z0-9:\(\/\)\s\.,!~]/g, ""); return input; } This successfully trims out unwanted characters in the likeMessage variable, but the character still gets entered into the text box. I would like to stop that from happening. I know it will have something to do with $("#like").val() but the only thing I can think of is just chopping off the end character from the text box value, would this suffice? Thanks for any help!

• Why vba doesnt handling Error 2042

  - by Jonathan Raul Tapia Lopez

  I have a variable "fila" with a full line with excel's values; The problem is when in excel I have --#N/A-- vba take that value like "Error 2042" and I cannot asign that value to "valor" and produce me an error, until this point everything is ok, now I am trying to define a "On error goto" for go to the "next" iteration in the loop "for", but I dont know Why vba doesnt handle the error. Do While Not IsEmpty(ActiveCell) txt = ActiveCell.Value2 cell = ActiveCell.Offset(0, 1).Value2 fila = Range("C20:F20") For j = 1 To UBound(fila, 2) On Error GoTo Siguiente If Not IsEmpty(fila(1, j)) Then valor = fila(1, j) cmd = Cells(1, j + 2).Value2 devolver = function1(cmd, txt, cell, valor) arrayDevolver(p) = devolver p = p + 1 End If Siguiente: Next Loop '

• What's the Difference Between These Two Ruby Class Initialization Definitions?

  - by michaelmichael

  I'm working through a book on Ruby, and the author used a slightly different form for writing a class initialization definition than he has in previous sections of the book. It looks like this: class Ticket attr_accessor :venue, :date def initialize(venue, date) self.venue = venue self.date = date end end In previous sections of the book, it would've been defined like this: class Ticket attr_accessor :venue, :date def initialize(venue, date) @venue = venue @date = date end end Is there any functional difference between using the setter method, as in the first example, vs. using the instance variable as in the second? They both seem to work. Even mixing them up works: class Ticket attr_accessor :venue, :date def initialize(venue, date) @venue = venue self.date = date end end

• ant cpptask with ivy

  - by AC

  A company I am working for, has some c binaries build with ant using cpptask. They use ivy to retrieve shared c libraries every time we start a build which wastes a significant amount of time comparing the revisions and downloading, when then only need to be download if the header files have changed. I have added a target which sets a var, which causes the build to skip over the ivy steps but I'd like a better solution. I see that cpptask creates a file history.xml and only rebuilds to binary if any of the sources have change. I'd like to know if there is way to independently test if the binary needs to build, and it does, I'd like it fire off the ivy targets. I'd also like for a variable to be set if the binary was rebuilt so that I can conditionally start an rpm generation task

  I have a comma-separated list of values, for example: strins s = "param1=true;param2=4;param3=2.0f;param4=sometext;"; I need a functions: public bool ExtractBool(string parameterName, string @params); public int ExtractInt(string parameterName, string @params); public float ExtractFloat(string parameterName, string @params); public string ExtractString(string parameterName, string @params); Is there a special functions in .net that can help me with csl ? PS: parameter names are equal within a list.

• C# Count registry keys existing using a partial value

  - by cheeseman

  Microsoft.Win32.RegistryKey registryPath = Microsoft.Win32.Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Wow6432Node\Testing"); Microsoft.Win32.RegistryKey entryKey = registryPath.OpenSubKey("Entry Point"); I have a lot of keys in Testing, in the format: "Entry Point 011", "Entry Point 123" - so Entry Point with random numbers after it. Would I be able to search the registryPath variable above and get a count of the number of keys containing the "Entry Point" keyword? Assuming that there are also other keys existing without this keyword. At the moment I have been using a for loop and looping for all possible combinations to get a count of all the keys, checking if the key exists or not, but as there are keys as high as "Entry Point 9000" having a for loop execute 9000 times is very inefficient. for (int i = 0; i <= highestEntryPointValue; i++) { Microsoft.Win32.RegistryKey entryKey = steamApps64.OpenSubKey("Entry Point " + Convert.ToString(i)); if (entryKey != null) { count++; } }

• a nicer way to create structs in a loop

  - by sandra

  Hi guys, I haven't coded in C++ in ages. And recently, I'm trying to work on something involving structs. Like this typedef struct{ int x; int y; } Point; Then in a loop, I'm trying to create new structs and put pointers to them them in a list. Point* p; int i, j; while (condition){ // compute values for i and j with some function... p = new Point; p* = {i, j}; //initialize my struct. list.append(p); //append this pointer to my list. } Now, my question is it possible to simplify this? I mean, the pointer variable *p outside of the loop and calling p = new Point inside the loop. Isn't there a better/nicer syntax for this?

• Why does File::Find finished short of completely traversing a large directory?

  - by Stan

  A directory exists with a total of 2,153,425 items (according to Windows folder Properties). It contains .jpg and .gif image files located within a few subdirectories. The task was to move the images into a different location while querying each file's name to retrieve some relevant info and store it elsewhere. The script that used File::Find finished at 20462 files. Out of curiosity I wrote a tiny recursive function to count the items which returned a count of 1,734,802. I suppose the difference can be accounted for by the fact that it didn't count folders, only files that passed the -f test. The problem itself can be solved differently by querying for file names first instead of traversing the directory. I'm just wondering what could've caused File::Find to finish at a small fraction of all files. The data is stored on an NTFS file system.

• ucommerce: how to change category template

  - by autonomatt

  Using uCommerce 2, umbraco 4.7. I have a category side nav showing the categories using: <a> <xsl:attribute name="href"> <xsl:value-of select="CommerceLibrary:GetNiceUrlForCategory($catalogueName, @id)"/> </xsl:attribute> <xsl:value-of select="@displayName"/> </a> First of all, when hovering over the links it still shows an old catalogue name, even though I've renamed the catalogue and also hardcoded the catalogue name into: <xsl:variable name="catalogueName" select="'MyCatalogue'"/> When I click on the link generated by GetNiceUrlForCategory I get the standard template that comes with uCommerce started site. I've tried deleting the whole started site, but I just can't get it to link to a template I did for the category. I still don't quite understand how ucommerce knows which template to use for a category link. Soren? :) Cheers, Matt

• NSCFType keeps occurring, something is not being released?

  - by user1493543

  I'm attempting to delete files from the documents directory using a tableview/array combination. For some reason, my NSString pointing to the Documents directory path is being converted to a NSCFType (which after some research, I understand is happening because a variable is not being released). Because of this, the application crashes at the line NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; claiming that NSCFType cannot recognize the method stringByAppendingPathComponent. I would appreciate if someone could help me out (I hope I have explained this clearly enough). - (void) tableView: (UITableView *) tableView commitEditingStyle: (UITableViewCellEditingStyle) editingStyle forRowAtIndexPath: (NSIndexPath *) indexPath { if (editingStyle == UITableViewCellEditingStyleDelete) { NSString *temp = [directoryContent objectAtIndex:indexPath.row]; NSLog(temp); NSString *lastPath = [documentsDirectory stringByAppendingPathComponent:temp]; [[NSFileManager defaultManager] removeItemAtPath:lastPath error:nil]; - (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath { paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES); documentsDirectory = [paths objectAtIndex:0]; directoryContent = [[[NSFileManager defaultManager] contentsOfDirectoryAtPath:documentsDirectory error:nil] retain]; //tableview handling below }

• Exclusive filtering by tag

  - by KaptajnKold

  I'm using rails 3.0 and MySql 5.1 I have these three models: Question, Tag and QuestionTag. Tag has a column called name. Question has many Tags through QuestionTags and vice versa. Suppose I have n tag names. How do I find only the questions that have all n tags, identified by tag name. And how do I do it in a single query. (If you can convince me that doing it in more than one query is optimal, I'll be open to that) A pure rails 3 solution would be preferred, but I am not adverse to a pure SQL solution either.

• Can my app arrange a gdb breakpoint or watch?

  - by Larry Gritz

  Is there a way for my code to be instrumented to insert a break point or watch on a memory location that will be honored by gdb? (And presumably have no effect when gdb is not attached.) I know how to do such things as gdb commands within the gdb session, but for certain types of debugging it would be really handy to do it "programmatically", if you know what I mean -- for example, the bug only happens with a particular circumstance, not any of the first 11,024 times the crashing routine is called, or the first 43,028,503 times that memory location is modified, so setting a simple break point on the routine or watch point on the variable is not helpful -- it's all false positives. I'm concerned mostly about Linux, but curious about if similar solutions exist for OS X (or Windows, though obviously not with gdb).

• $("body").scrollTop() doesn't update in safari

  - by Kristoffer Nolgren

  I'm working on a website: http://beta.projektopia.se/ the body has several background-images that are updated on scroll like this: $(document).ready(function(){ $(document).scroll(function(){ var scrollfactor=$("body").scrollTop()*0.2; var centerscrollpos =scrollfactor+613; var docheight = $(document).height(); var windowheight = $(window).height(); var bottompos = (docheight-980)-((docheight-windowheight)*0.2)+scrollfactor; var scrollpos = 'center '+scrollfactor+'px,center '+bottompos+'px, center '+ centerscrollpos+'px,center 0px'; $("body").css("background-position", scrollpos); }); }); Lots of calculations, but the important thing is that a scrollpos is created that should change the position of the background when you scroll, to create a parallax-effect. It works great in chrome, but in firefox, the variable scrollfactor, that is suppose to get the current scroll-position, doesn't update. ps, some people have this issue due to lack of correct doctype. I believe i have declared it correctly like this: <!DOCTYPE html>

• How to paste text and variables into a logical expression in R?

  - by Jasper

  I want to paste variables in the logical expression that I am using to subset data, but the subset function does not see them as column names when pasted (either with ot without quotes). I have a dataframe with columns named col1, col2 etc. I want to subset for the rows in which colx < 0.05 This DOES work: subsetdata<-subset(dataframe, col1<0.05) subsetdata<-subset(dataframe, col2<0.05) This does NOT work: for (k in 1:2){ subsetdata<-subset(dataframe, paste("col",k,sep="")<0.05) } for (k in 1:2){ subsetdata<-subset(dataframe, noquote(paste("col",k,sep=""))<0.05) } I can't find the answer; any suggestions?

• Pass Session data to a Class Library without using a bunch of constructors?

  - by sah302

  Hi all, I've got my application here where literally every object has a lastUpdatedBy property. The information I put into here is the person's username, which is retrieved from the session("username") variable. How can I pass this data to my DAL in the class library? At first I was just passing in the value into each method, but this is ridiculous I thought, there should be no reason to do that every time a method is called. Then I thought well if I just put it in a constructor for each of the DAL related classes, that will make it even easier. However, even still on any given page, I've got a plethora of New() declarations, for which every single line I need to pass in the session username casted as a string. Is there an even still more efficient way of doing this so that I could only declare this in one place, and everything will know what it is and I can pass it to classes in a class library?

• Passing value from :locals to link_remote_to

  - by Teef L

  In my edit.haml file, I have =render :partial => 'old_question_tags', :locals => {:current_question => @question.id}. I'd like to pass the value in :current_question to a link_to_remote call in _old_question_tags.haml: #{link_to_remote image_tag('red-x.png', {:alt => "Remove #{t.name} tag"}), :url => {:action => 'remove_old_tag_from_question', :tag_remove => t.id, :current_question => current_question}} But I get this error on the link_to_remote line: ActionView::TemplateError (undefined local variable or method `current_question' for #<ActionView::Base:0xdb2fec8>) In _old_question_tags.haml, if I just print current_question (using =current_question), it prints the number without any problems. How do I properly pass that value to the partial so that I can pass it to the link_to_remote call?

• C++ IDE for Linux with smart reference searching

  - by Dmitry Yudakov

  Is there an IDE supporting C++ with REALLY smart searching of references? By 'reference' I mean usage of a class (or its member), variable, function in the whole Project or Workspace. There's lots of IDE providing it. Some of them seem just to search for the text with same name giving lots of stuff, others are smarter and check the context (like class boundaries, namespace) but aren't accurate enough. The best I've tried so far was Visual SlickEdit, but still there's more to wish. class C1 { int foo; }; class C2 { int foo; }; For example in this situation when searching for C1::foo references I don't want C2::foo to be shown too. So, is there an IDE that would be so smart?

• EJB injection in Glassfish webapp

  - by g051051

  I've got an app that is trying to use @EJB annotation to inject remote references to EJBs in my ejb.jar file. I'm getting inconsistent results. In one case, I have a listener in web.xml that gets called and apparently has the EJB injected correctly, since I can see it connecting to the EJB and calling methods on it. In another class (a struts2 action) I get NPE when it tries to access the EJB reference. As far as I can tell, they're identical calls, in Java classes that live in the same .war file. As a work around, I added code in the constructor to lookup the EJBs by their global JNDI names, and it works fine. I just can't figure out why one @EJB works and not another.

• Why does this symfony code not work?

• [JS/jQuery] Using argument (this) passed via element eventhandler

  - by Kel

  Hey guys, I want to use the argument I pass (this) in a JS function and treat it as an jQuery variable. Example: <script> function useMe(obj){ $(obj).val(); ... ... ... } </script> <select id="selectid" onChange="useMe(this)"> <option>......</option> </select> Is there a possibility to treat the passed argument as a jQuery element? Btw. I need to do it this way, because the select-element isn't created on load. The select element will be created later asynchronously. So, this won't work: $("select").each(function (i){ var select_id = $(this).attr("id"); $(this).change(function(e){ because it doesn't exist yet. Thanks for your help.

• Rails Load Data into Application every time a New User is Created

  - by looloobs

  Hi I am trying to figure out the "right" way to do this. In my application every time I create a new user I want to have specific data loaded into an associated table. The associated table is a different preset lists. So a User has many lists and those lists have many items. Some of those Items I want to be loaded when the User is created. I really don't know how to go about doing this but I am guessing something like: create User after_create: create Lists (need already existing data for the list names) after_create List then populate Items table with existing data for these Lists. Should I be using seed data for this? Is that alright for production and if so how exactly would I go about doing that. Any guidance or other recommendations are greatly appreciated.

• Why doesn't splicing an object from an array in Javascript return the array?

  - by Allen Gould

  I have an array of objects (say, a deck of cards): var deck = []; deck.push(new Card(suit, rank)); The following seems to work: var card = deck.pop(); var card = deck.shift(); (pulling from the "top" or "bottom" of the deck respectively) But if I want a card from the middle (say, if this was a hand of cards) var card = deck.splice(2,1); The object doesn't seem to get properly assigned to the variable (everything is undefined). Everything I look up says that splice should return the object that I'm removing - what am I missing?

• Alter Git prompt on Windows

  - by kko

  I'm using Git on Windows, installed through GitExtensions with MSysGit (latest) having selected "do not modify my Windows prompt" during installation. Now, I would like to be able to modify the default prompt (which by default shows just the branch name to also show me how much time, and how many local commits since I last pushed to origin (or specifically origin/master, whichever is easier). So say instead of: me@myPC /c/myRepo (master) I would see something along the lines of: me@myPC /c/myRepo (master) 5 | 10:20 meaning I have last pushed 10h 20min ago and I have made 5 local commits since. Before you mention it, I am aware there are ways of doing it with PowerShell, but I don't want to use it. I want my standard git bash we all know and love. I found a few solutions to that, with modifying PS1 variable in .bashrc file, but (excuse my poor Unix konwledge) they seem to be not working, (for example accepted answer to this question). So there you have it. Is this possible?
