  • Using the filename for GET data and making the PHP page output as a JPG extension?

    - by Rob
    Alright, currently I'm using GD to create a PNG image that logs a few different things, depending on the GET data, for example: http://example.com/file.php?do=this will log one thing while http://example.com/file.php?do=that will log another thing. However, I'd like to do it without GET data, so instead http://example.com/dothis.php will log one thing, and http://example.com/dothat.php will log the other. But on top of that, I'd also like to make it accessible via the JPG file extension. I've seen this done but I can't figure out how. So that way http://example.com/dothis.JPG will log one thing, while http://example.com/dothat.JPG logs the other. The logging part is simple, of course. I simple need to know how to use filenames in place of the GET data and how to set the php file to be accessible via a jpg file extension.

  • SQL Native Client 10 Performance miserable (due to server-side cursors)

    - by namezero
    we have an application that uses ODBC via CDatabase/CRecordset in MFC (VS2010). We have two backends implemented. MSSQL and MySQL. Now, when we use MSSQL (with the Native Client 10.0), retrieving records with SELECT is dramatically slow via slow links (VPN, for example). The MySQL ODBC driver does not exhibit this nasty behavior. For example: CRecordset r(&m_db); r.Open(CRecordset::snapshot, L"SELECT a.something, b.sthelse FROM TableA AS a LEFT JOIN TableB AS b ON a.ID=b.Ref"); r.MoveFirst(); while(!r.IsEOF()) { // Retrieve CString strData; crs.GetFieldValue(L"a.something", strData); crs.MoveNext(); } Now, with the MySQL driver, everything runs as it should. The query is returned, and everything is lightning fast. However, with the MSSQL Native Client, things slow down, because on every MoveNext(), the driver communicates with the server. I think it is due to server-side cursors, but I didn't find a way to disable them. I have tried using: ::SQLSetConnectAttr(m_db.m_hdbc, SQL_ATTR_ODBC_CURSORS, SQL_CUR_USE_ODBC, SQL_IS_INTEGER); But this didn't help either. There are still long-running exec's to sp_cursorfetch() et al in SQL Profiler. I have also tried a small reference project with SQLAPI and bulk fetch, but that hangs in FetchNext() for a long time, too (even if there is only one record in the resultset). This however only happens on queries with LEFT JOINS, table-valued functions, etc. Note that the query doesn't take that long - executing the same SQL via SQL Studio over the same connection returns in a reasonable time. Question1: Is is possible to somehow get the native client to "cache" all results locally use local cursors in a similar fashion as the MySQL driver seems to do it? Maybe this is the wrong approach altogether, but I'm not sure how else to do this. All we want is to retrieve all data at once from a SELECT, then never talk the server again until the next query. We don't care about recordset updates, deletes, etc or any of that nonsense. We only want to retrieve data. We take that recordset, get all the data, and delete it. Question2: Is there a more efficient way to just retrieve data in MFC with ODBC?

  • Efficient bitshifting an array of int?

    - by nn
    Hi, To be on the same page, let's assume sizeof(int)=4 and sizeof(long)=8. Given an array of integers, what would be an efficient method to bitshift the array to either the left or right? I am contemplating an auxiliary variable such as a long, that will compute the bitshift for the first pair of elements (index 0 and 1) and set the first element (0). Continuing in this fashion the bitshift for elements (index 1 and 2) will be computer, and then index 1 will be set. I think this is actually a fairly efficient method, but there are drawbacks. I cannot bitshift greater than 32 bits. I think using multiple auxiliary variables would work, but I'm envisioning recursion somewhere along the line.

  • SQL Server 2008 - Get Geography From Record

    - by user336786
    Hello, I am new to using the geography types in SQL Server 2008. I have a table in my database called "Location". "Location" has the following columns and types: Location -------- City nvarchar(256) State nvarchar(256) PostalCode nvarchar(25) Latitude decimal(9, 6) Longitude decimal(9, 6) Each Location is related to a Store record in my database. I am trying to find the stores within a 10 mile radius or postal code or city/state that a user enters. To accomplish this, I know that I need to rely on geographies. At this time I have: DECLARE @startingPoint geography; SET @startingPoint=geography::STGeomFromText('POINT(-122.34900 47.65100)', 4326); That gives me the starting point from a hard-coded textual value. However, I do not know how to convert a lat/long from my Location table into a geography instance. How do I convert a lat/long in my database to a geography instance so I can continue to work on my query? Thank you!

  • Generics vs Object performance

    - by Risho
    I'm doing practice problems from MCTS Exam 70-536 Microsft .Net Framework Application Dev Foundation, and one of the problems is to create two classes, one generic, one object type that both perform the same thing; in which a loop uses the class and iterated over thousand times. And using the timer, time the performance of both. There was another post at C# generics question that seeks the same questoion but nonone replied. Basically if in my code I run the generic class first it takes loger to process. If I run the object class first than the object class takes longer to process. The whole idea was to prove that generics perform faster. I used the original users code to save me some time. I didn't particularly see anything wrong with the code and was puzzled by the outcome. Can some one explain why the unusual results? Thanks, Risho Here is the code: class Program { class Object_Sample { public Object_Sample() { Console.WriteLine("Object_Sample Class"); } public long getTicks() { return DateTime.Now.Ticks; } public void display(Object a) { Console.WriteLine("{0}", a); } } class Generics_Samle<T> { public Generics_Samle() { Console.WriteLine("Generics_Sample Class"); } public long getTicks() { return DateTime.Now.Ticks; } public void display(T a) { Console.WriteLine("{0}", a); } } static void Main(string[] args) { long ticks_initial, ticks_final, diff_generics, diff_object; Object_Sample OS = new Object_Sample(); Generics_Samle<int> GS = new Generics_Samle<int>(); //Generic Sample ticks_initial = 0; ticks_final = 0; ticks_initial = GS.getTicks(); for (int i = 0; i < 50000; i++) { GS.display(i); } ticks_final = GS.getTicks(); diff_generics = ticks_final - ticks_initial; //Object Sample ticks_initial = 0; ticks_final = 0; ticks_initial = OS.getTicks(); for (int j = 0; j < 50000; j++) { OS.display(j); } ticks_final = OS.getTicks(); diff_object = ticks_final - ticks_initial; Console.WriteLine("\nPerformance of Generics {0}", diff_generics); Console.WriteLine("Performance of Object {0}", diff_object); Console.ReadKey(); } }

  • iPhone simulator app crashes when appending a string

    - by Franklyn Weber
    Hi, I'm a complete novice, so I'm probably missing something really easy, but I can't get my string appending to work. I add the 3rd character to typedDigit & it crashes - the method is called fine and typedDigit will get to 2 characters long. I think everything is declared properly in the header file. Code is - -(IBAction)digitPressed:(UIButton *)sender { NSString *digit = [[sender titleLabel] text]; // in this case, "0" - "9" if (userIsInMiddleOfTyping) { // typedDigit is already at least 1 character long typedDigit = [typedDigit stringByAppendingString:digit]; } else { // first character of typedDigit typedDigit = digit; userIsInMiddleOfTyping = YES; } } Many thanks for any help!

  • Help with Linq and Generics

    - by Jonathan
    Hi to all. I'm triying to make a function that add a 'where' clause to a query based in a property and a value. This is a very simplefied version of my function. Private Function simplified(ByVal query As IQueryable(Of T), ByVal PValue As Long, ByVal p As PropertyInfo) As ObjectQuery(Of T) query = query.Where(Function(c) DirectCast(p.GetValue(c, Nothing), Long) = PValue) Dim t = query.ToList 'this line is only for testing, and here is the error raise Return query End Function The error message is: LINQ to Entities does not recognize the method 'System.Object CompareObjectEqual(System.Object, System.Object, Boolean)' method, and this method cannot be translated into a store expression. Looks like a can't use GetValue inside a linq query. Can I achieve this in other way? Post your answer in C#/VB. Chose the one that make you feel more confortable. Thanks

  • How can I intercept a Tomcat request at socket level?

    - by Miguel Pardal
    Hi, I'm doing a performance study for a web application framework running on Apache Tomcat 6. I'm trying to measure the time overhead of handling HTTP requests. What I would like to do is: / // just before first request byte is read long t1 = System.nanoTime(); // request is processed... // just after final byte is written to response long t2 = System.nanoTime(); / Then I would compute the total time (t2 - t1). Is there a way to do this? Thanks for your help!

  • Is my program taking too much time to execute?

    - by Conrad C
    I wanted to solve a question from project euleur about finding the largest prime number of a big number. I run my code on a virtual machine on Visual studio 2012, and the code seems froze. When I step into the loop, the code works well, but when I execute it, the console is always there. It is as if the program is still running. Could it be that the program takes time to execute? My Code static void Main(string[] args) { long number = 5; for (long i = 1; i < 600851475143; i++) { if (i % 2 != 0 && i % 1 == 0 && i % i == 0) number = i; } }

  • Creating an n tiered application

    - by aaron
    I am researching architecture for a project that will be started next year. It is mainly a c# web app, but there will be a service layer so that it can talk to our facebook/iphone app. There are a few long running processes, which means that I will be creating a windows process that can handle those. I’m thinking of putting the entire app in the windows service instead of just the long running processes. Asp - wcf - bll Vs Asp - bll I know this will be more scalable. But it is probably overkill as everything will be running on the same box, even the database. This could change down the road if the server can’t handle the traffic like marketing says it will. I don’t have access to production hardware, just my crappy testing box and my local machine. Has anyone decided to go down this route? But mostly, what is the best way to test both methods to get some metrics?

  • How to get only a filename (not full path) into $1, using the PERL, regular expressions

    - by Scott
    I want to keep only the filenames (not full paths) and add the filename to some bbcode. Here is the HTML to be converted: <a href=/path/to/full/image.jpg rel=prettyPhoto><img rel=prettyPhoto src=/path/to/thumb/image.jpg /></a> Notice I cannot have rel="foo" (no double quotes).. Here is what I have in PERL, to perform the conversion: s/\<a href=(.+?)\ rel=prettyPhoto\>\<img rel=prettyPhoto src=(.+?) \/>\<\/a\>/\[box\]$1\[\/box\]/gi; This converts the HTML to: [box]/path/to/image.jpg[/box] But this is what I want as a result: [box]image.jpg[/box] The HTML must remain the same. So how do I change my PERL so that $1 contains only the filename?

  • PHP Fatal error on line number that doesn't exist

    - by alexantd
    Fatal error: Allowed memory size of 134217728 bytes exhausted (tried to allocate 523800 bytes) in /Library/WebServer/Documents/XMLDataStore.class.php on line 981 The curious thing about this error is not the memory leak, which would be easy enough to troubleshoot. Rather, it is the fact that XMLDataStore.class.php is only 850 lines long, which I have verified in multiple text editors. This is with the PHP 5.3 bundled with Snow Leopard. I'm not using an opcode cache. Here is my php.ini: allow_url_fopen = Off error_reporting = -1 display_errors = 1 display_startup_errors = 1 date.timezone = 'America/Los_Angeles' output_buffering = Off realpath_cache_size = 0k XMLDataStore.class.php has recently been refactored and it used to be longer than 981 lines. It's almost as if PHP has cached a 2-week-old version and is reading that. I'm positive that the current version at /Library/WebServer/Documents/XMLDataStore.class.php is only 850 lines long, though.

  • Radius of multiple latitude/longitude points

    - by zekial
    I have a program that takes as input an array of lat/long points. I need to perform a check on that array to ensure that all of the points are within a certain radius. So, for example, the maximum radius I will allow is 100 miles. Given an array of lat/long (coming from a MySQL database, could be 10 points could be 10000) I need to figure out if they will all fit in a circle with radius of 100 miles. Kinda stumped on how to approach this. Any help would be greatly appreciated.

  • How to extract a single function from a source file

    - by Adam Matan
    Hi, I'm working on a small academic research about extremely long and complicated functions in the Linux kernel. I'm trying to figure out if there is a good reason to write 600 or 800 lines-long functions. For that purpose, I would like to find a tool that can extract a function from a .c file, so I can run some automated tests on the function. For example, If I have the function cifs_parse_mount_options() within the file connect.c, I'm seeking a solution that would roughly work like: extract /fs/cifs/connect.c cifs_parse_mount_options and return the 523 lines of code(!) of the function, from the opening braces to the closing braces. Of course, any way of manipulating existing software packages like gcc to do that, would be most helpful too. Thanks, Udi EDIT : The answers to Regex to pull out C function prototype declarations? convinced me that matching function declaration by regex is far from trivial.

  • Inconsistent Behavior From Declared DLL Function

    - by Steven
    Why might my GetRawData declared function return a correct value when called from my VB.NET application, but return zero when called from my ASP.NET page? The code is exactly the same except for class type difference (Form / Page) and calling event handler (Form1_Load, Page_Load). Note: In the actual code, #DLL# and #RAWDATAFILE# are both absolute filenames to my DLL and raw data file respectively. Note: The DLL file was not created by Visual Studio. Form1.vb Public Class Form1 Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Private Sub Form1_Load(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles MyBase.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length) Default.aspx.vb Partial Public Class _Default Inherits System.Web.UI.Page Declare Auto Function GetRawData Lib "#DLL#" (ByVal filename() As Byte, _ ByVal byteArray() As Byte, _ ByVal length As Int32) As Int32 Protected Sub Page_Load(ByVal sender As Object, _ ByVal e As System.EventArgs) Handles Me.Load Dim buffer(10485760) As Byte Dim msg As String, length As Integer = 10485760 Dim filename As String = "#RAWDATAFILE#" length = GetRawData(Encoding.Default.GetBytes(filename), buffer, length)

  • Does program need additional symbols from .so shared library except those declared in header file?

    - by solotim
    In C programming, I thought that a object file can be successfully linked with a .so file as long as the .so file offers all symbols which have been declared in the header file. Suppose I have foo.c, bar.h and two libraries libbar.so.1 and libbar.so.2. The implementation of libbar.so.1 and libbar.so.2 is totally different, but I think it's OK as long as they both offers functions declared in bar.h. I linked foo.o with libbar.so.1 and produced an executable: foo.bin. This executable worked when libbar.so.1 is in LD_LIBRARY_PATH.(of course a symbolic link is made as libbar.so) However, when I change the symbolic link to libbar.so.2, foo.bin could not run and complainted this: undefined symbol: _ZSt4cerr I found this symbol type is 'B' and it does not appear in libbar.so.2. Obviously this symbol has nothing to do with those functions I decared in bar.h. What's wrong here?

  • Project hosting on Google Code. Files are cahced?

    - by Frexuz
    I do not really understand how Google Code handles file versioning. I am building a jQuery plugin that anyone can access. Like so: <script type="text/javascript" src="http://jquery-old-browser-warning.googlecode.com/files/jquery.browser-warning.js"></script> This script accesses other files on the same project (via ajax). The problem is, that when I upload a new file, it just seems like there aren't any changed to it. Google recommends that new files should have new names. But then I would have to change the filenames that the script loads. But then I would have to change the script file as well, and that would break everybodys implementation (with the script-tag above) Is there a way to force a file to change when uploading with the same filename? PS: If I go directly to the project page's file list. Then I do get the file with the updated content. But as I said, not when getting it through ajax.

  • PHP Get images from a UL list

    - by benjamin shrimpton
    I have a long UL list and each LI contains an image tag, dynamically generated from SLideshowPro Director. I need to get the widths of ALL the images inside the UL to use in a CSS width calculation. I have been able to get the image width for the first item, but not all. My PHP is pretty limited, but do I have to make this list into an ARRAY first to allow me to get all the widths? And how do i do that?? These images contain very long id's generated by the CMS, so reading through a directory is not possible, as the images in cache bare not relation to the file names that are output to the HTML page. It has to all be done from the content that's sent to the page. Or could I even use JQuery to do this??
