• Integrating a ClickOnce app with Outlook

  - by AngryHacker

  I have a ClickOnce app that used to be run by users with Power User privileges. So to integrate to outlook (e.g. syncing of emails, appointments and addresses) I used a 3rd party component from Add-In Express, which includes an ActiveX DLL. So when the user would download my app, I'd register the ActiveX DLL (if it wasn't already registered) and then would just interop with it in the application. Well, now the users had their privileges changed to standard limited User. Which means that they can't register DLLs (since it writes to the registry keys that are off limit). And the integration with Outlook fails, of course. What are some of options to integrate with Outlook for my situation?

• Sorting array containing strings in objective c

  - by jakob

  Hello experts! I have an array named 'names' with strings looking like this: ["name_23_something", "name_25_something", "name_2_something"]; Now I would like to sort this array in ascending order so it looks like this: ["name_25_something", "name_23_something", "name_2_something"]; I guess that should start of with extracting the numbers since I want that the sorting is done by them: for(NSString *name in arr) { NSArray *nameSegments = [name componentsSeparatedByString:@"_"]; NSLog("number: %@", (NSString*)[nameSegments objectAtIndex:1]); } I'm thinking of creating a dictionary with the keys but I'm not sure if that is the correct objective-c way, maybe there some some methods I could use instead? Could you please me with some tips or example code how this sorting should be done in a proper way. Thank you

• TreeMap randomly stops properly returning values

  - by smessing

  I have the following TreeMap: TreeMap<String, Integer> distances = new TreeMap<String, Integer>(); and it contains both strings, "Face" and "Foo", with appropriate values, such that: System.out.println(distances); Yields: {Face=12, Foo=2} However, distances.get(Face) returns null, even though distances.get(Foo) properly returns 2. Previously, distances.get(Face) worked, but for some reason, it stopped working. Note I print out the map right before calling get() for both keys, so I haven't accidentally changed Face's value to null. Has anyone else ever encountered this problem? Is there anything I can do? I'm having a terrible time simply trying to figure out how to debug this problem.

• How do you share your git repository with other developers?

  - by semi

  I have a central git repository that everyone pushes to for testing and integration, but it only is pushed to when features are 'ready'. While in the middle of a big task, developers frequently have many commits that stay on their harddrives. Sometimes in the middle of these projects I'd like to either see what another developer is doing, or show him how I've done something. I'd like to be able to tell another developer to just "pull my working copy" The only way I can think of is having everyone run ssh on their development machines and adding accounts or ssh keys for everyone, but this is a huge privacy and permissions nightmare, and seems like a lot of work to maintain. Should we just be pushing to that central repository in these cases? Should we be pushing after every local commit?

• How to automize multiple projects build process by including digital signature of exe in Delphi?

  - by user193655

  After building a project group of 2 projects with Delphi (2009) I digitally sign the 2 exes using InstallAware Code signing, an exe that shipped with Delphi 2009. How is it possible to automize the digital signature, so when I build I can also attach digital signature. For digital signing I use a pvk (private key) file and an spc (Sw publisher certificate) file. Subquestion: Moreover I created a project group because I have 2 exes, but they are almost the same, the only thing that changes is the Application icon and the application name (one is ProductOne.dpr, the other is ProductTwo.dpr). In practice I have 2 brands of the same product, I have a single build but activation keys details activate one or the other, anyway now I was asked to change the icon and the filename, and for this I need to build 2 projects, activation key is not enough anymore to distinguish between the 2. Anyway if there is a way to do this from a single project it would be better.

• Can you restrict entering invalid keystrokes with jquery ui autocomplete combobox

  - by oo

  when using the jquery ui autocomplete combobox, i would thought there would be an option to force only valid key entry based on the list. Is there anyway to not allow invalid keys so you can only enter valid items in the list? also, is there a way to set a default value of the combobox. if my list has (csharp, java, python) i can start typing "abcds . ." and it lets me type it in. I want only valid entries to be allowed.

• Removing $_SESSION['layout']['action'] globally from all users!

  - by sologhost

  Ok, I am storing a session variable like so to load up users layouts faster if it's set instead of calling the database. But since the layout can be changed via the Administrator, I'd like to be able to globally remove all sessions where $_SESSION['layout']['action'] is set for all users. $_SESSION['layout']['action'] = array(a ton of indexes and mulit-dimensional arrays); Now, I know it's being stored into my database sessions table, there's a column for session_id, last_update, and data. So, question I have is how to remove that session array key ['action'] from all users. Using $_SESSION = array(); session_destroy(); Does not work. Basically, session_start() is being loaded on every page load, so I just want to remove all ['action'] keys from ['layout']. Is this possible to do? Thanks

• Keyboard input for a game in Java

  - by hmp

  I'm writing a game in Java, right now it's Swing + JOGL - a JFrame with a GLCanvas. I handle input using keyPressed etc. events (jframe.addKeyListener(...)) and it doesn't seem to work properly: when I have 3+ keys down at the same time, they don't register properly after the window loses, then regains focus, input stops working completely... What am I doing wrong? Is there a better way of handling keyboard input in Java? (I'd rather not switch to another library, like LWJGL... unless I have no choice).

• Is there any way to limit the size of an STL Map?

  - by Nathan Fellman

  I want to implement some sort of lookup table in C++ that will act as a cache. It is meant to emulate a piece of hardware I'm simulating. The keys are non-integer, so I'm guessing a hash is in order. I have no intention of inventing the wheel so I intend to use stl::map for this (though suggestions for alternatives are welcome). The question is, is there any way to limit the size of the hash to emulate the fact that my hardware is of finite size? I'd expect the hash's insert method to return an error message or throw an exception if the limit is reached. If there is no such way, I'll simply check its size before trying to insert, but that seems like an inelegant way to do it.

• How to compare two maps by their values

  - by lewap

  How to compare two maps by their values? I have two maps containing equal values and want to compare them by their values. Here is an example: Map a = new HashMap(); a.put("f"+"oo", "bar"+"bar"); a.put("fo"+"o", "bar"+"bar"); Map b = new HashMap(); a.put("f"+"oo", "bar"+"bar"); a.put("fo"+"o", "bar"+"bar"); System.out.println("equals: " + a.equals(b)); // obviously false .... what to call to obtain a true? Obviously, to implement a comparison it not difficult, it is enough to compare all keys and their associated values. I don't believe I'm the first one to do this, so there must be already a library functions either in java or in one of the jakarta.commons libraries. Thanks

• Git fatal: remote end hung up

  - by Bill

  So I thought I had finally got everything setup on Windows ... then ran into this issue. Current setup URL: ssh://user@host:port/myapp.git Already run Putty - and can connect using valid .ppk keys through the ~/.ssh/authorized_keys direct. In Git and TortoiseGIT - I set both to use "plink.exe". Putty works fine - no issues - but when I run that URL into bash I get for a git clone (url) fatal: the remote end hung up expectedly In a cygwin bash terminal - running "ssh user@host" - works no probs at all. Anyone suggest anything?

• Calculating co-ordinate of a point on a path given a distance

  - by Alex

  I'm working on a project that surveys the condition of a road or highway using a calibrated trip computer connected to a rugged-PC. An operator keys in defect codes as they travel along a pre-defined route. I need to show an indicator on the map screen that shows the vehicles current position, taking into account the distance data from the trip computer. I know the exact lat lon co-ordinates at the starting point of each section of road, and the road is made up of a series of points. The question is: how can I calculate the lat lon co-ordinates of the vehicle assuming that it has continued on the route and traveled a certain distance (e.g. 1.4km). The co-ordinates would be 'locked onto' the road line, as shown in blue on the diagram below. Thanks, Alex

• how to write mute logic when mute state is unknown

  - by Delan Azabani

  I'm writing an indicator-sound clone for OSS4. Setting the volume works fine now, but I'm having trouble with the muting aspect of my program. A couple of facts about muting in OSS4: vmix doesn't have a mute (and we use vmix for volume control) also, the 'media keys' way of controlling volume doesn't set a mute control, but rather, volume = 0 The problem with this is, when reading the vmix volume and encountering zero, we don't know if the user has actually set it to zero, or has it set to some other value, but has mute on. How should I write my muting logic? git code, if that helps

• Choice of primary index for mysql innoDB

  - by Saif Bechan

  I have an auction website where users can place a bid on a product. Now i have a primary index on the bid table for easy access of the last places bid on the product. This index is just a unique auto incrementing value. During the week this number becomes huge!! I was wondering if this is a good setup for the primary key in an innoDB table. The bids table exist of the following important fields: table: bids fields: user_id,product_id,bid So what i want to do is make the primary of these 3 fields combined. Is this a good idea or is this just too much for innoDB keys.

• 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.

• Correct usage of Voldemort as key-value pair?

  - by zengr

  Hello, I am trying to understand, how can Voldermort be used? Say, I have this scenario: Since, Voldemort is a key-value pair. I need to fetch a value (say some text) on the basis of 3 parameters. So, what will be the key in this case? I cannot use 3 keys for 1 value right, but that value should be search able on the basis of those 3 parameters. Am I making sense? Thanks EDIT1 eg: A blog system. A user posts a blog: User's data stored: Name, Age and Sex The blog content (text) is stored. Now, I need to use Voldemort here, if a user searches from the front end for all the blog posts by Sex: Male Then, my code should query voldemort and return all the "blog content (text)" which have Sex as Male.

• Possible: Set Operations on Disparate Maps with Same Key Type?

  - by Catskul

  Let's say I have two maps: typedef int Id; std::map<Id, std::string> idToStringMap; std::map<Id, double> idToDoubleMap; And let's say I would like to do a set operation on the keys of the two maps. Is there an easier way to do this than to create a custom "inserter" iterator? such that I could do something like: std::set<Id> resultSet; set_difference( idToStringMap.begin(), idToStringMap.end(), idToDoubleMap.begin(), idToDoubleMap.end(), resultSet.begin() ); My experimentation results imply that it will be necessary to create a custom inserter and perhaps a custom key comparer to do this, but I want for some insight/shortcut before doing so.

• How to catch Keyboard and mouse events?

  - by Alexey Malistov

  I want to create an application. This application has to do something when a user presses special keys on keyboard or/and uses scroll wheel. This application is a service. It has no windows. I want to catch any keyboard or mouse events which were designed with other applications. For example, you are watching TV by 3rd party application. If you press Ctrl + Shift and use scroll wheel my application changes the volume. I use Windows 7 x64 and Visual Studio 2008.

• How to make an invisible button to run a command

  - by Denis Mitropolskiy

  I have a form with TextBox and two Buttons. One button has IsDefault property set to true, and IsCancel set to true for other button. TextBox is CommandTarget for both buttons. When I'm pressing Enter or ESC keys on TextBox, it works as I'm pressing on corresponding button. I want to remove buttons from the form. They should not be visible, but the textbox should react on Enter or ESC as before. I cannot just set button's Visible property to collapsed - in this case they does not work at all. And I prefer to avoid of tracking keyboard events. Is it possible?

• Actionscript 3 Navigate with Keyboard Between Labels

  - by Sbml

  Hello I need to navigate between labels with arrow keys like a power point presentation. I have an array with labels and a KeyboardEvent. My problem is, if I am in label number four for example and click in arrow click, always goes to first label. So I need help defining my current label to go to the next on key press. My code: import flash.events.KeyboardEvent; var myLabels:Array = [ "label_1", "label_2", "label_3", "label_4"]; var nextLabel:String; var inc:int = 0; stage.addEventListener(KeyboardEvent.KEY_DOWN, keyPressed); function keyPressed(evt:KeyboardEvent):void { switch(evt.keyCode) { case Keyboard.RIGHT : nextLabel = String(myLabels[inc]); gotoAndStop(nextLabel); inc++; break; } } Thanks

• extracting secrets from an embedded chip

  - by Will

  I am looking at an embedded system where secrets are stored in flash that is internal to the chip package, and there is no physical interface to get that information out - all access to this flash is policed by program code. All DMA attacks and JTAG and such are disabled. This seems to be a common locked-down configuration for system-on-a-chip. How might an attacker recover the secrets in that Flash? I understand they can fuzz for vulnerabilities in the app code and exploit it, that there could be some indistinct general side channel attack or something. But how would an attacker really go about trying to recover those keys? Are there viable approaches for a determined attacker to somehow shave-down the chip or some kind of microscope attack?

• Entities groups in transactions

  - by Joel

  In the context of "Keys and Entity Groups" article by google: http://code.google.com/appengine/docs/python/datastore/transactions.html 1) "Only use entity groups when they are needed for transactions" 2) "Every entity belongs to an entity group, a set of one or more entities that can be manipulated in a single transaction." It seems like entity groups exist only for the use of transactions, i.e. making one transaction possible between all entities in a group. My question is then why are there parent-child relations between entities and not just a simple declaration of entities to be in a single group (that is defining A,B,C to be in the same group as opposed to defining relations between them "A (parent of) B, B (parent of C)"). What is the benefit from using parent-child relation model when the only purpose is for entities to be in the same group to make transaction possible? Thanks Joel

• add ANOTHER primary key to a table which is UNIQUE

  so im having problems with adding another primary key to my table. i have 3 columns: 1. Account ID (Identity) 2. EmailID 3. Data field when i made the table i had this to make the Account ID and the Email ID unique PRIMARY KEY (AccountID, EmailID) i thought that would make my emailid unique, but then after i tried inserting another row with the same emailid it went through. so i thought i missed something out. now for my question: IF, i had to use alter, How do i alter the table/PK Constraint to modify the EmailID field and make it Unique IF i decided to drop the table and made a new one, how do i make those two primary keys uniqe?
