  • Get the lua command when a c function is called

    - by gamernb
    Supposed I register many different function names in Lua to the same function in C. Now, everytime my C function is called, is there a way to determine which function name was invoked? for example: int runCommand(lua_State *lua) { const char *name = // getFunctionName(lua) ? how would I do this part for(int i = 0; i < functions.size; i++) if(functions[i].name == name) functions[i].Call() } int main() { ... lua_register(lua, "delay", runCommand); lua_register(lua, "execute", runCommand); lua_register(lua, "loadPlugin", runCommand); lua_register(lua, "loadModule", runCommand); lua_register(lua, "delay", runCommand); } So, how do I get the name of what ever function called it?

  • Relevance of 'public' constructor in abstract class.

    - by Amby
    Is there any relevance of a 'public' constructor in an abstract class? I can not think of any possible way to use it, in that case shouldn't it be treated as error by compiler (C#, not sure if other languages allow that). Sample Code: internal abstract class Vehicle { public Vehicle() { } } The C# compiler allows this code to compile, while there is no way i can call this contructor from the outside world. It can be called from derived classes only. So shouldn't it allow 'protected' and 'private' modifiers only. Please comment.

  • Is there a way to access the locale used by gettext under windows ?

    - by phtrivier
    I have a program where i18n is handled by gettext. The program works fine, however for some reason I need to know the name of the locale used by gettext at runtime (something like 'fr_FR') under win32. I looked into gettext sources, and there is a quite frightening function that computes it on all platforms (gl_locale_name, in a C file called "localename.h/c"). However, this file does not seem to be installed alongside gettext or libintl, so I can't seem to call the function. Is there another function provided by gettext to get this value ? Or in another package (boost, glib, anything ?) (On a related note, there is a thing called std::locale in the C++ standard library, and according to the doc calling std::locale("") should create a locale with the settings of the system, unless I am mistaken ... but then the name is 'C' under windows. Is it a viable way of getting the locale name ? What I am doing wrong ?)

  • Retrieving data from MySQL in one SQL statement

    - by james.ingham
    Hi all, If I'm getting my data from Mysql like so: $result = $dbConnector->Query("SELECT * FROM branches, businesses WHERE branches.BusinessId = businesses.Id ORDER BY businesses.Name"); $resultNum = $dbConnector->GetNumRows($result); if($resultNum > 0) { for($i=0; $i < $resultNum; $i++) { $row = $dbConnector->FetchArray($result); // $row['businesses.Name']; // $row['branches.Name']; echo $row['Name']; } } Does anyone know how to print the field Name in businesses and how to print the name from branches? My only other alternative is to rename the fields or to call Mysql with two seperate queries. Thanks in advance

  • C# method generic params parameter bug?

    - by Mike M
    Hey, I appears to me as though there is a bug/inconsistency in the C# compiler. This works fine (first method gets called): public void SomeMethod(string message, object data); public void SomeMethod(string message, params object[] data); // .... SomeMethod("woohoo", item); Yet this causes "The call is ambiguous between the following methods" error: public void SomeMethod(string message, T data); public void SomeMethod(string message, params T[] data); // .... SomeMethod("woohoo", (T)item); I could just use the dump the first method entirely, but since this is a very performance sensitive library and the first method will be used about 75% of the time, I would rather not always wrap things in an array and instantiate an iterator to go over a foreach if there is only one item. Splitting into different named methods would be messy at best IMO. Thoughts?

  • Login method Customization using GINA [closed]

    - by netseng
    DUPLICATE:http://stackoverflow.com/questions/523912/login-method-customization-using-gina Hi All, I know it's not easy to find a master in GINA, but my question is most near to Interprocess Communication(IPC), I wrote my custom GINA in unmanaged c++, I included it a method that checks for validity of a fingerprint for the user try to login, this function will call some method in a running system windows service written in c#, the code follows: in GINA, unmanaged c++ if(Fingerprint.Validate(userName,finerprintTemplate) { //perform login } in windows service, C# public class Fingerprint { public static bool Validate(string userName, byte[] finerprintTemplate) { //Preform Some code to validate fingerprintTemplate with userName //and retuen result } } Does anyone know how to do such Communication between GINA and the windows service, or simply between c++ written service and C# written service. Thanks

  • How to remove duplicate line in a file

    - by Abs
    Hi I'm using the below method to write to a file from the Jtextarea and I call this method every 30 second within a Timer but instead to add only new line in file it rewrite the entire lines contained in Jtextarea so then I have duplicate lines. I want to avoid this and update the file just with new lines. Could you help me please. public void loger() { FileWriter writer = null; try { writer = new FileWriter("MBM_Log_"+date()+".txt" , true); textArea.write(writer); } catch (IOException exception) { System.err.println("log error"); exception.printStackTrace(); } finally { if (writer != null) { try { writer.close(); } catch (IOException exception) { System.err.println("Error closing writer"); exception.printStackTrace(); } } } }

  • jQuery-AJAX to rebind dropdown list to results from stored procedure

    - by webworm
    I have a dropdown list of peoples names that is quite long. As many as 2,000 names. I would like to make it easier to find the name the user is interested in by limiting the dropdown list to a subset of names at a time. I have done this by creating a series of 26 links (A, B, C ... Z) that call a method in the code behind that populates the dropdown list with only those names starting with the letter the user clicked. This all works well but I would like to be able to use AJAX to accomplish this update of the dropdown list without a page refresh. I would like to use jQuery for the AJAX functionality rather than ASP.NET AJAX. My problem is I am not sure how to execute the stored procedure and then "rebind" the dropdown list with the new dataset via jQuery AJAX. Any suggestions or resources that might provide and example or walk-through? Thank you.

  • Suggestions: Anti-Pattern counter-examples

    - by Tom W
    It doesn't seem that this exact question has been asked before, so I'll fire away: Most of us are familiar with the concept of an anti-pattern. However, avoiding implementation of anti-patterns can in principle swing too far the other way and cause problems itself. As an example, "Design by Committee" has a counter-example that I'd call "Design by Maverick" - wherein the design of an important feature is handed off to an individual to do what they think best, with the intention of reviewing their work later and deciding whether it should be finalised or go through another iteration. This takes much longer in practice as the rest of the team are occupied by other things, and can end up with a feature that's useful to nobody, particularly if the Maverick is not themselves an experienced end-user. Does anyone have any more examples of anti-pattern counter-examples?

  • Sending SMTP e-mail at a high rate in .NET

    - by Martin Liversage
    I have a .NET service that processes a queue on a background thread and from the items in the queue sends out a large number of small e-mail messages at a very high rate (say 100 messages per second if that is even possible). Currently, I use SmtpClient.Send() but I'm afraid that it may hamper performance. Each call to Send() goes through a full cycle of opening the socket, performing the SMTP conversation (HELO, MAIL FROM, RCPT TO, DATA) and closing the socket. In pseudo code: for each message { open socket send HELO send MAIL FROM send RCPT TO send DATA close socket } I would think that the following pseudo code would be more optimal: open socket send HELO for each message { send MAIL FROM send RCPT TO send DATA } send QUIT close socket Should I be concerned about the performance of SmtpClient.Send() when sending e-mail at a high rate? What are my options for optimizing the performance?

  • Keep a reference to an NSThread around and message its objects?

    - by RickiG
    Hi I am a bit uncertain on how to do this: I start a "worker-thread" that runs for the duration of my apps "life". [NSThread detachNewThreadSelector:@selector(updateModel) toTarget:self withObject:nil]; then - (void) updateModel { NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init]; BackgroundUpdate *update = [[BackgroundUpdate alloc] initWithTimerInterval:5]; [[NSRunLoop currentRunLoop] run]; //keeps it going 'forever' [update release]; [pool release]; } Now the thread "wakes" up every 5 seconds(initWithTimerInterval) to see if there are any tasks it can do. All the tasks in the BackGroundUpdate Class are only time dependent for now. I would like to have a few that were "event dependent". e.g. I would like to call the Background Object from my main thread and tell it to "speedUp", "slowDown", "reset" or any method on the object. To do this I guess I need something like performSelectorOnThread but how to get a reference to the NSthread and the Background Object?

  • make: invoke command for multiple targets of multiple files?

    - by marvin2k
    Hi, I looking to optimize an existing Makefile. It's used to create multiple plots (using Octave) for every logfile in a given directory using an scriptfile for every plot which takes a logfilename as an argument. In the Moment, I use one single rule for every kind of plot available, with a handwritten call to Octave, giving the specific scriptfile/logfile as an argument. It would be nice, if every plot has "his" octave-script as a dependency (plus the logfile, of course), so only one plot is regenerated if his script is changed. Since I don't want to type that much, I wonder how I can simplifiy this by using only one general rule to build "a" plot? To make it clearer: Logfile: "$(LOGNAME).log" Scriptfile: "plot$(PLOTNAME).m" creates "$(LOGNAME)_$(PLOTNAME).png" The first thing I had in mind: %1_%2.png: %1.log $(OCTAVE) --eval "plot$<2('$<1')" But this seems not to be allowed. Could someone give me a hint?

  • Issue with Visual C++ 2010 (Express) External Tools command

    - by espais
    I posted this on SuperUser...but I was hoping the pros here at SO might have a good idea about how to fix this as well.... Normally we develop in VS 2005 Pro, but I wanted to give VS 2010 a spin. We have custom build tools based off of GNU make tools that are called when creating an executable. This is the error that I see whenever I call my external tool: ...\gnu\make.exe): * couldn't commit memory for cygwin heap, Win32 error 487 The caveat is that it still works perfectly fine in VS2005, as well as being called straight from the command line. Also, my external tool is setup exactly the same as in VS 2005. Is there some setting somewhere that could cause this error to be thrown?

  • Can I use manifests to specify an optional dependency on a COM server?

    - by sharptooth
    I'd like to use manifests to specify a dependency on a COM server (reg-free COM). The consumer application will mostly work fine without the COM server - only something like 1,7% of its functionality uses the COM server. So with plain old regsvr32 it would start and work fine until the user would do something that would trigger CoCreateInstance() call and at that point the consumer would get an error message. Now I've played with manifests for a while and it looks like the consumer wouldn't even start unless the COM server assembly it depends on is present in the file system. That's no good. Is there a way to use reg-free COM with manifests and make the dependency optional - so that the consumer program starts and works fine until CoCreateInstance() is actually called?

  • Override Java System.currentTimeMillis

    - by Mike Clark
    Is there a way, either in code or with JVM arguments, to override the current time, as presented via System.currentTimeMillis, other than manually changing the system clock on the host machine? A little background: We have a system that runs a number of accounting jobs that revolve much of their logic around the current date (ie 1st of the month, 1st of the year, etc) Unfortunately, a lot of the legacy code calls functions such as new Date() or Calendar.getInstance(), both of which eventually call down to System.currentTimeMillis. For testing purposes, right now, we are stuck with manually updating the system clock to manipulate what time and date the code thinks that the test is being run. So my question is: Is there a way to override what is returned by System.currentTimeMillis? For example, to tell the JVM to automatically add or subtract some offset before returning from that method? Thanks in advance!

  • Accessing mapped network drive from ColdFusion

    - by Kip
    I am having a problem accessing a mapped drive in ColdFusion. I have \\server\files\sharing mapped to z:\. If I run this code, it says the directory exists for the full path but not for the mapped one: <cfscript> fullPath = "\\server\files\sharing\reports"; mappedPath = "z:\reports"; WriteOutput("fullPath exists: #DirectoryExists(fullPath)#<br/>"); //YES WriteOutput("mappedPath exists: #DirectoryExists(mappedPath)#"); //NO </cfscript> I have done some Googling and have found a few people with the same problem, but the solution was always to use the full path. Is there a reason ColdFusion wouldn't be able to see or access the mapped drive? And if so, are there any workarounds (maybe a system call to get the full path of the mapped drive)?

  • Get class of caller's method (via inspect) in Python (alt: super() emulator)

    - by Slava Vishnyakov
    Is it possible to get reference to class B in this example? class A(object): pass class B(A): def test(self): test2() class C(B): pass import inspect def test2(): frame = inspect.currentframe().f_back cls = frame.[?something here?] # cls here should == B (class) c = C() c.test() Basically, C is child of B, B is child of A. Then we create c of type C. Then the call to c.test() actually calls B.test() (via inheritance), which calls to test2(). test2() can get the parent frame frame; code reference to method via frame.f_code; self via frame.f_locals['self']; but type(frame.f_locals['self']) is C (of course), but not B, where method is defined. Any way to get B?

  • Can someone give me an overview of ASP.net and how it's different from technologies such as php?

    - by DavidR
    I've been doing the html and css for a site, sending it off to a guy to implement in a web server. I get a call from the designer freaking out about the progress, saying the clients aren't happy. He wants me to personally integrate my css with what's on the site. The site is done in ASP.net, time is short, and I'm a little in over my head. I have an understanding of how php works, but have never worked extensively with it. Looking at the stuff on the ftp, I can't even find equivalent of the index.html file (I know that when I go to the site itself, there is nothing after the base url, i.e., www.site.com/ brings me to the homepage.) Can anyone give me a few tips or links as to what I am to do with this, or where to even being navigating this site?

  • design using a readonly class in c#

    - by edosoft
    Hi Small design question here. I'm trying to develop a calculation app in C#. I have a class, let's call it InputRecord, which holds 100s of fields (multi dimensional arrays) This InputRecordclass will be used in a number of CalculationEngines. Each CalculcationEngine can make changes to a number of fields in the InputRecord. These changes are steps needed for it's calculation. Now I don't want the local changes made to the InputRecord to be used in other CalculcationEngine's classes. The first solution that comes to mind is using a struct: these are value types. However I'd like to use inheritance: each CalculationEngine needs a few fields only relevant to that engine: it's has it's own InputRecord, based on BaseInputRecord. Can anyone point me to a design that will help me accomplish this?

  • JavaScript on Android randomly stops working

    - by AndersWid
    Hi! I have an application that uses a WebView and a html-page with javascript functions. Randomly the JavaScript functions doesn't seem to be called. It works up to a random point (I have looked at this bug all day) can only be produced on hardware (HTC Legend) not on emulator. Basicly I'm using callback to javaScript whenever the user presses a button, these callbacks tell the html to redraw using javaScript functions. mHandler.post(new Runnable() { public void run() { mWebView.loadUrl("javascript:getDataLine()"); } }); The first line in this javaScript code is an alert that says that it has started, so that I can see that it's working. Settings alerts or console.log's everywhere won't help as it seems the problem is in the webview or in Android itself. I need a way to see what's going on in the background. Maybe see if a previous call failed and stalled the thread or something.

  • Save BLOB to disk as Image C#

    - by TGuimond
    Hello, I am developing a web application that calls web services developed by a third party to send/receive data from a clients database. I am building the application using ASP.NET 3.5 C#. The way that they are providing me images is in BLOB format. I call their method and what I get back is a DataSet with 2 fields "logo_name" and "logo" which is the BLOB field. What I want to do is: Save the image locally on the disk (to minimize calls to their database in the future). I have been playing around with a couple of different ways of doing this but cannot seem to get the image to save correctly. I have been able to create a file in a folder with the correct name but if I try to view the image it does not work. I was hoping someone could give me some sample code to show me how to save a BLOB field to the local disk? Thanks
