  • Using Library files in Linux

    - by paultop6
    Hi Guys, Im trying to use some of the functions that are in the /lib/libproc-3.2.6.so library in my Ubuntu Distribution. I have downloaded and installed the header files and they are defined in my source files. Currently this is all im trying to do, just for starters... proc_t **read_proc = readproctab(0); But i get the following compiler error: /tmp/cclqMImG.o: In function `Sysmon::initialise_sysmon()': sysmon.cpp:(.text+0x494): undefined reference to `readproctab' collect2: ld returned 1 exit status Im aware im probably doing some wrong with the command im using to compile it, but due to lack of experience im not sure what im doign wrong. This is the g++ command im using to compile my cpp file: g++ -o sysmon.o sysmon.cpp `pkg-config --libs --cflags gtk+-2.0` Can someone please give me some pointers as to where im going wrong Regards Paul

  • struts validation problem in IE

    - by user265201
    I am using Struts 2.1.8 and facing validation problem in IE. I am getting the following error An exception occurred: Error. Error message: Invalid argument. I tried out to figure out the cause and found the following. My generated javascript code is: field = form.elements['district.name']; var error = "Enter only alphabets for district"; if (continueValidation && field.value != null && !field.value.match("^[a-zA-Z ]*$")) { addError(field, error); errors = true; } I tried to mock up by putting the same code in a function and calling it in onclick event. The method addError() throws the exception and the reason is field variable. If I change it to field[0], it works fine. How to fix this error?

  • Source Insight: Show me Enum Values

    - by JXG
    I'm programming in C and using Source Insight. I have an enum type with a lot of constants (like 100). I have debug prints that print out variable values, but they (of course) print out as integers. What I'd like to do is click on the name of an enum constant, and see its numeric value displayed somewhere. (I've seen this done in a Visual Studio plugin, so it must be possible.) That is, assume I have enum colors { ORANGE, PURPLE, PINK }; I want to click on (or select, or something) PURPLE and see the value 1 somewhere visible (ideally, the symbol window or context window, but I'm not particular). Is there an easy way to do this in Source Insight? Is there a difficult way, at least (such as writing a macro)?

  • Git push origin master

    - by user306472
    I posted this question early yesterday, but the thread seems to have died out. For reference, see http://stackoverflow.com/questions/2619117/git-push-origin-master . Here's the low-down: I'm new to git. I just set up an account with github and I followed all their instructions flawlessly until I got to the last command of git push origin master Upon entering this command, I get the error message "fatal: No path specified. See 'man git-pull' for valid url syntax." If I type in git origin show the output I see is origin. If I type in git remote -n show the output is * remote origin URL: [email protected]: HEAD branch: (not queried) Local ref configured for 'git push' (status not queried): (matching) pushes to (matching) Please help me get to the bottom of this.

  • 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.

  • Capture Flash Audio in 4.7 Edge?

    - by emcmanus
    Is there a way to capture plugin (Flash) audio before it gets to the sound card? I'd like to record plugin audio, hopefully without actually playing the sound. Capturing audio at the device level is an absolute last resort, as the application would pick up all system audio rather than just the Webkit plugin. I'm aware of the recent switch back from QTMultimedia; is this possible with phonon? I spent the night looking for some way to access the phonon graph via QWebFrame (or any of the QtWebkit widgets) -- and didn't turn up much. I also started digging through QTWebkit, particularly NPAPI, without success. For reference, I'm using the edge version of 4.7 (6aa50af000f85cc4497749fcf0860c8ed244a60e) This seems to be a fairly challenging problem. Any hints would be greatly appreciated.

  • Double encoded url being fully decoded in ASP.NET

    - by Brad R
    I have just come across something that is quite strange and yet I haven't found any mention on the interwebs of others having the same problem. If I hit my ASP.NET application with a double encoded url then the Request["myQueryParam"] will do a double decode of the query for me. This is not desirable as I have double encoded my query string for a good reason. Can others confirm I'm not doing something obviously wrong, and why this would happen. A solution to prevent it, without doing some nasty query string parsing, would be great too! As an example if you hit the url: http://localhost/MyApp?originalUrl=http%3a%2f%2flocalhost%2fAction%2fRedirect%3fUrl%3d%252fsomeUrl%253futm_medium%253dabc%2526utm_source%253dabc%2526utm_campaign%253dabc (For reference %25 is the % symbol) Then look at the Request["originalUrl"] (page or controller) the string returned is: http://localhost/Action/Redirect?Url=/someUrl?utm_medium=abc&utm_source=abc&utm_campaign=abc I would expect: http://localhost/Action/Redirect?Url=%2fsomeUrl%3futm_medium%3dabc%26utm_source%3dabc%26utm_campaign%3dabc I have also checked in Fiddler and the URL is being passed to the server correctly (one possible culprit could have been the browser decoding the URL before sending).

  • Application of a rule based expert system

    - by simon
    Hi, The company I am working now has developed a Rule-based Expert System. It is a web-based system and supports Flow Chart, Decision Table, Fuzzy Rules and Forward Chaining Rules. It is something like iLog but less complex and powerful. However, one serious problem we are facing now is that we have NO CUSTOMER so far. We have spent 4 yrs to develop that product. Because my company is a start-up and has no reference, no one is confident in our product. Without feedback, we cannot improve our product. I am wondering if we should change our product into SAAS and make it free for people to try, or it has NO MARKET at all. (I will lose my job then..) Please give me some suggestions. Many Thanks!

  • Where Are the Release Versions of ASP.Net AJAX 4.0 Templating Files?

    - by Lee Richardson
    I'm trying to get the production version of ASP.Net AJAX 4.0 Templating working and can't find the JavaScript files. With the beta version I needed to reference MicrosoftAjaxTemplates.js, MicrosoftAjaxAdoNet.js, and MicrosoftAjaxDataContext.js. I can get everything to work with the beta CDN versions (e.g. http://ajax.microsoft.com/ajax/beta/0911/MicrosoftAjaxTemplates.js). But for the life of me I can't find 1. The release CDN versions of these files or 2. Where to download the whole Release ASP.Net AJAX 4.0 JavaScript package. The files certainly are not listed on the ASP.Net AJAX 4.0 CDN at http://www.asp.net/ajaxlibrary/CDNAjax4.ashx. Maybe the files have been renamed? Theoretically this should be a rediculously easy question and I'm a little embarrased to even ask it on StackOverflow, but I've had no luck finding an answer on my own. Any help would be much appreciated. Thanks, - Lee

  • Birt Global Integer

    - by matschie
    Hi there I have a Birt Report which read some stuff from a database. After that i want to increment a global Integer for every Detailrow that is loaded. So far i have initialized a global Integer with the following lines: importPackage(Packages.java.lang); reportContext.setPersistentGlobalVariable("minTotalPlus", new Integer(0)); After that i added the following line into a field in my detail row: reportContext.setGlobalVariable("minTotalPlus", new Integer reportContext.getGlobalVariable("minTotalPlus")) + 1); When i preview the report i get an "java.lang.NumberFormatException: null" which means that the global variable is null. Why is that so? How could I fix that?

  • Custom cell just failing

    - by ct2k7
    Hi, I'm trying to use a custom UITableViewCell, and I've placed it in the same nib file as the UITableView controller. For this, the files are: NTItems.h, NTItems.m and NTItems.xib. I have defined the cell in the header file: IBOutlet UITableViewCell *cellview; and I've correctly applied the property: nonatomic, retain so it's there. In the m file - I've synthesized the variable device and am using this to get the custom cell: if(cell == nil){ cell = self.cellview; } However, when I load the table, I get this horrible mess: There should be more than 1 cell showing data as well. On another note, how do I map the labels to the text which is to be displayed?

  • What's the fastest way to check the availability of a SQL Server server?

    - by mwolfe02
    I have an MS Access program in use in multiple locations. It connects to MS SQL Server tables, but the server name is different in each location. I am looking for the fastest way to test for the existence of a server. The code I am currently using looks like this: ShellWait "sc \\" & ServerName & " qdescription MSSQLSERVER > " & Qt(fn) FNum = FreeFile() Open fn For Input As #FNum Line Input #FNum, Result Close #FNum Kill fn If InStr(Result, "SUCCESS") Then ... ShellWait: executes a shell command and waits for it to finish Qt: wraps a string in double quotes fn: temporary filename variable I run the above code against a list of server names (of which only one is normally available). The code takes about one second if the server is available and takes about 8 seconds for each server that is unavailable. I'd like to get both of these lower, if possible, but especially the fail case as this one happens most often.

  • Errata for Java Language Specification 3rd Edition

    - by polygenelubricants
    I use JLS extensively both as a learning and teaching resource, but I've noticed that there are some errors in it. There's the simple typos (e.g. JLS 5.1.4 "convesions"), but there's also some that I consider quite serious errors. For example, JLS 18.1 The Grammar of the Java Programming Language is supposed to be the authoritative reference for the grammar of the Java language, but it contains a production rule that never gets used! (e.g. MoreStatementExpressions). Surely this is a sign of more serious errors in other parts of the given grammar, right? So is there an errata for the 3rd edition? Will there ever be? Should we send errors we've found to Sun/Oracle? Will there ever be a 4th edition?

  • Android and config.xml

    - by synic
    Looking in the android sdk folders, I've found a file called values/config.xml. This seems to be somewhere that you can define values for later use in layouts and animations. Given the config.xml: <resources> <string name="config_somePadding">50dip</string> </resources> How would I reference this to use as the layout_height in a layout xml file? @string/config_somePadding is actually the only one I've found that doesn't throw an error in Eclipse (even though there isn't a config_somePadding in values/strings.xml), but it appears to just put an empty string.

  • How does the Garbage Collector decide when to kill objects held by WeakReferences?

    - by Kennet Belenky
    I have an object, which I believe is held only by a WeakReference. I've traced its reference holders using SOS and SOSEX, and both confirm that this is the case (I'm not an SOS expert, so I could be wrong on this point). The standard explanation of WeakReferences is that the GC ignores them when doing its sweeps. Nonetheless, my object survives an invocation to GC.Collect(GC.MaxGeneration, GCCollectionMode.Forced). Is it possible for an object that is only referenced with a WeakReference to survive that collection? Is there an even more thorough collection that I can force? Or, should I re-visit my belief that the only references to the object are weak?

  • How do I create a MessageBox in C# ?

    - by Nick Stinemates
    I have just installed C# for the first time, and at first glance it appears to be very similar to VB6. I decided to start off by trying to make a 'Hello, World!' UI Edition. I started in the Form Designer and made a button named "Click Me!" proceeded to double-click it and typed in MessageBox("Hello, World!"); I received the following error: MessageBox is a 'type' but used as a 'variable' Fair enough, it seems in C# MessageBox is an Object. I tried the following MessageBox a = new MessageBox("Hello, World!"); I received the following error: MessageBox does not contain a constructor that takes '1' arguments Now I am stumped. Please help.

  • R - Specifying colClasses in the read.csv

    - by Derek
    Hi, I am trying to specify the colClasses options in the read.csv function in R. In my data, the first column "time" is basically a character vector while the rest of the columns are numeric. data<-read.csv("test.csv" , comment.char="" , colClasses=c(time="character","numeric") , strip.white=FALSE) In the above command, I would want R to read in the "time" column as "character" and the as numeric. Although, the "data" variable did have the correct result after the command completed, R returned the following warnings. I am wondering how I could fix these warnings? Warning messages: 1: In read.table(file = file, header = header, sep = sep, quote = quote, : not all columns named in 'colClasses' exist 2: In tmp[i[i > 0L]] <- colClasses : number of items to replace is not a multiple of replacement length Thank in advance Derek

  • How to detect the language of MS Excel from C#

    - by Babba
    If i try to use Excel from C# (interop) i receive error (HRESULT: 0x80028018) when current thread language is different from Excel language: so i need to set thread language, they must be the same. Which is the best method to understand the language of Excel/Office? 1) registry (HKEY_CURRENT_USER\Software\Microsoft\Office\12.0\Common\LanguageResources\UILanguage ?

  • Is SynchronizationContext.Post() threadsafe?

    - by cyclotis04
    This is a pretty basic question, and I imagine that it is, but I can't find any definitive answer. Is SynchronizationContext.Post() threadsafe? I have a member variable which holds the main thread's context, and _context.Post() is being called from multiple threads. I imagine that Post() could be called simultaneously on the object. Should I do something like lock (_contextLock) _context.Post(myDelegate, myEventArgs); or is that unnecessary? Edit: MSDN states that "Any instance members are not guaranteed to be thread safe." Should I keep my lock(), then?

  • How can I easily pass all the variables from a template to a partial in Symfony with output escaping

    - by Failpunk
    It there an easy way to pass all the variables a template file has access to onto a partial when I have output escaping on? I tend to create a template file, then refactor things into a partial at some point and it would seem that there would be an easy way to just pass all the same variables from the template to the partial and be done with it. I have output escaping on and I can't just pass in $sf_data. It look like calling a partial from within another partial is very simple...just pass in the variable $vars.

  • Read SharedPreferences when you haven't set the name of the file.

    - by Pentium10
    When you createa a PreferenceScreen on Android, your application creates a default SharedPreferences file for the settings. I want to read this name, or get a reference without specifing the name. Currently I use: SharedPreferences prefs = ctx.getSharedPreferences("prefs", 0); SharedPreferences.Editor ed=prefs.edit(); But this returns another copy of the preference. When I checked the folder in /data/data/myapk/shared_prefs I see two files, one named prefs.xml and the other is my [package name]_preferences.xml (this was created by the PreferenceActivity); How do I get an instance of the shared preference with the usage of the default file name, so I should not mention a name for it?
