  • URL Friendly regular expression

    - by Caesar
    Can anyone help me with regular expression for this: basically I have a search form and users type in whatever keywords they want to search and when a search button is clicked, the search keyword is appended to the url (see examples below). Note the keyword may contain any character. Example 1 Search key: whatever you want URL: www.example.com/search/whatever+you+want/ Example 2 Search key: oh boy! what's going on? URL: www.example.com/search/oh+boy!+what's+goin+on%3F What regular expression can I use to capture all characters in the ASCII table between 32 to 126?

I have a requirement to output the contents of the db (not actual schema above, but concept is similar) in both fixed width and delimited formats. The above FOR XML PATH query gives me the result I want, but when dealing with anything other than small amounts of data, can take awhile. I've looked at pivot but most of the examples I have found are aggregating information. I just to combine the child rows and tack them onto the parent. For example, for an order it would need to output: OrderId,Product1,Product2,Product3,etc Thoughts or suggestions? I am using SQL Server 2k5.

  • Accurate Timings with Oscilloscopes on PC

    - by Paul Bullough
    In the world of embedded software (firmware) it is fairly common to observe the order of events, take timings and optimise a program by getting it to waggle PIO lines and capturing their behavior on an oscilloscope. In days gone by it was possible to toggle pins on the serial and parallel ports to achieve much the same thing on PC-based software. This made it possible to capture host PC-based software events and firmware events on the same trace and examine host software/firmware interactions. Now, my new laptop ... no serial or parallel ports! This is increasingly the case. So, does anyone have any suggestions as to go about emitting accurate timing signals off a "modern" PC? It strikes me that we don't have any immediately programmable, lag-free output pins left. The solution needs to run off a laptop, so using add-on cards that only plug into desktops are not permitted.

  • Use an Array to Cycle Through a MySQL Where Statement

    - by Ryan
    I'm trying to create a loop that will output multiple where statements for a MySQL query. Ultimately, my goal is to end up with these four separate Where statements: `fruit` = '1' AND `vegetables` = '1' `fruit` = '1' AND `vegetables` = '2' `fruit` = '2' AND `vegetables` = '1' `fruit` = '2' AND `vegetables` = '2' My theoretical code is pasted below: <?php $columnnames = array('fruit','vegetables'); $column1 = array('1','2'); $column2 = array('1','2'); $where = ''; $column1inc =0; $column2inc =0; while( $column1inc <= count($column1) ) { if( !empty( $where ) ) $where .= ' AND '; $where = "`".$columnnames[0]."` = "; $where .= "'".$column1[$column1inc]."'"; while( $column2inc <= count($column2) ) { if( !empty( $where ) ) $where .= ' AND '; $where .= "`".$columnnames[1]."` = "; $where .= "'".$column2[$column2inc]."'"; echo $where."\n"; $column2inc++; } $column1inc++; } ?> When I run this code, I get the following output: `fruit` = '1' AND `vegetables` = '1' `fruit` = '1' AND `vegetables` = '1' AND `vegetables` = '2' `fruit` = '1' AND `vegetables` = '1' AND `vegetables` = '2' AND `vegetables` = '' Does anyone see what I am doing incorrectly?

  • How can you prevent an individual window being captured by Print-Screen?

    - by John
    I noticed a few times than when I print-screen while Media Player is running, the content is replaced with a grey rectangle. I've no idea if it's deliberate due to DRM, or some technical issue, but it struck me that being able to deliberately block screen-capture might be a useful feature in some scenarios. I am not looking to fix the problem, but replicate it! Is there some specific message each HWND gets for print-screen - does Windows do a special repaint or simply dump buffers to the clipboard? I guess I'd prefer to focus this on Win32 specifically, but as long as it's Windows-related then fine.

  • How to convert struct to char array in C

    - by falcojr
    I'm trying to convert a struct to a char array to send over the network. However, I get some weird output from the char array when I do. #include <stdio.h> struct x { int x; } __attribute__((packed)); int main() { struct x a; a.x=127; char *b = (char *)&a; int i; for (i=0; i<4; i++) printf("%02x ", b[i]); printf("\n"); for (i=0; i<4; i++) printf("%d ", b[i]); printf("\n"); return 0; } Here is the output for various values of a.x (on an X86 using gcc): 127: 7f 00 00 00 127 0 0 0 128: ffffff80 00 00 00 -128 0 0 0 255: ffffffff 00 00 00 -1 0 0 0 256: 00 01 00 00 0 1 0 0 I understand the values for 127 and 256, but why do the numbers change when going to 128? Why wouldn't it just be: 80 00 00 00 128 0 0 0 Am I forgetting to do something in the conversion process or am I forgetting something about integer representation? *Note: This is just a small test program. In a real program I have more in the struct, better variable names, and I convert to little-endian. *Edit: formatting

    I try to encapsulate. Exeption from interface, static inner class working, non-static inner class not working, cannot understand terminology: nested classes, inner classes, nested interfaces, interface-abstract-class -- sounds too Repetitive! Exception 'illegal type' from interface apparently because values being constants(?!) static interface userInfo { File startingFile=new File("."); String startingPath="dummy"; try{ startingPath=startingFile.getCanonicalPath(); }catch(Exception e){e.printStackTrace();} } Working code but no succes with non-static inner class import java.io.*; import java.util.*; public class listTest{ public interface hello{String word="hello word from Interface!";} public static class hej{ hej(){} private String hejo="hello hallo from Static class with image"; public void printHallooo(){System.out.println(hejo);} } public class nonStatic{ nonStatic(){} //HOW TO USE IT? public void printNonStatic(){System.out.println("Inside static class with an image!");} } public static void main(String[] args){ //INTERFACE TEST System.out.println(hello.word); //INNNER CLASS STATIC TEST hej h=new hej(); h.printHallooo(); //INNER CLASS NON-STATIC TEST nonStatic ns=new nonStatic(); ns.printNonStatic(); //IS there a way to it without STATIC? } } Output The above code works but how non-staticly?

  • sizeof abuse : get the size of a const table

    - by shodanex
    When declaring a const table, it is possible to get the size of the table using sizeof. However, once you stop using the symbol name, it does not work anymore. is there a way to have the following program output the correct size for table A, instead of 0 ? #include <stdio.h> struct mystruct { int a; short b; }; const struct mystruct tableA[] ={ { .a = 1, .b = 2, }, { .a = 2, .b = 2, }, { .a = 3, .b = 2, }, }; const struct mystruct tableB[] ={ { .a = 1, .b = 2, }, { .a = 2, .b = 2, }, }; int main(int argc, char * argv[]) { int tbl_sz; const struct mystruct * table; table = tableA; tbl_sz = sizeof(table)/sizeof(struct mystruct); printf("size of table A : %d\n", tbl_sz); table = tableB; tbl_sz = sizeof(tableB)/sizeof(struct mystruct); printf("size of table B : %d\n", tbl_sz); return 0; } Output is : size of table A : 0 size of table B : 2

  • Strange casting problem with tm structure

    - by egiakoum1984
    I have the following casting problem when my data structure sSpecificData contains a field of type tm: typedef struct { unsigned char data[10000]; } sDataBuffer; typedef struct { int m_Id; sDataBuffer m_Data; } sData; typedef struct { int m_value1; int m_value2; tm m_Date; } sSpecificData; const int SPECIFIC_SVC_DATA_SIZE = sizeof(sSpecificData); typedef struct { int m_Id; sSpecificData m_Data; } sMyData; int main(void) { sData svc; sMyData* ptr1 = (sMyData*) &svc; sSpecificData* ptr2; ptr2 = (sSpecificData*) &svc.m_Data; ptr1->m_Data.m_value1 = 90; ptr1->m_Data.m_value2 = 80; cout << ptr1->m_Data.m_value1 << endl; cout << ptr1->m_Data.m_value2 << endl; cout << ptr2->m_value1 << endl; cout << ptr2->m_value2 << endl; return 0; } Without the field "tm m_Date;" as part of the sSpecificData, the output is correct: 90 80 90 80 With the field "tm m_Date;" as part of the sSpecificData, the output is wrong: 90 80 0 <-- ! 90 <-- ! Is there any idea why my example doesn't work when there is field of type tm as part of the sSpecificData? Thanks!

  • Drawing only part of a texture OpenGL ES iPhone

    - by Ben Reeves
    ..Continued on from my previous question I have a 320*480 RGB565 framebuffer which I wish to draw using OpenGL ES 1.0 on the iPhone. - (void)setupView { glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR); glTexParameteriv(GL_TEXTURE_2D, GL_TEXTURE_CROP_RECT_OES, (int[4]){0, 0, 480, 320}); glEnable(GL_TEXTURE_2D); } // Updates the OpenGL view when the timer fires - (void)drawView { // Make sure that you are drawing to the current context [EAGLContext setCurrentContext:context]; //Get the 320*480 buffer const int8_t * frameBuf = [source getNextBuffer]; //Create enough storage for a 512x512 power of 2 texture int8_t lBuf[2*512*512]; memcpy (lBuf, frameBuf, 320*480*2); //Upload the texture glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, 512, 512, 0, GL_RGB, GL_UNSIGNED_SHORT_5_6_5, lBuf); //Draw it glDrawTexiOES(0, 0, 1, 480, 320); [context presentRenderbuffer:GL_RENDERBUFFER_OES]; } If I produce the original texture in 512*512 the output is cropped incorrectly but other than that looks fine. However using the require output size of 320*480 everything is distorted and messed up. I'm pretty sure it's the way I'm copying the framebuffer into the new 512*512 buffer. I have tried this routine int8_t lBuf[512][512][2]; const char * frameDataP = frameData; for (int ii = 0; ii < 480; ++ii) { memcpy(lBuf[ii], frameDataP, 320); frameDataP += 320; } Which is better, but the width appears to be stretched and the height is messed up. Any help appreciated.

  • Opencv: Converting hue image to RGB image

    - by jhaip
    I am trying to show the hue component of the image from my webcam. I have split apart the image into the hue component but I can't figure out how to show the hue component as the pure colors. For example if one pixel of the image was B=189 G=60 R=60 then in HSV, H=0. I don't want the draw image to be the the gray values of hue but the RGB equivalent of the hue or H=0 - B=0 G=0 R=255 IplImage *image, *imageHSV, *imageHue; image = cvQueryFrame(capture); //image from webcam imageHSV = cvCreateImage( cvGetSize(image), IPL_DEPTH_8U, 3 ); imageHue = cvCreateImage( cvGetSize(image), IPL_DEPTH_8U, 1 ); cvCvtColor( image, imageHSV, CV_BGR2HSV ); cvSplit( imageHSV, imageHue, 0, 0, 0 ); I have a feeling there is a simple solution so any help is appreciated.

  • Pocket IE onmousedown onmousemove onmouseup ?

    - by eidylon
    Hello all, I have a control which I wrote for capturing signatures on a web page, by using onmousedown, onmousemove and onmouseup on a div to track the mouse, and capture points comprising a signature. Now we need this to work on Windows Mobile 6.5 powered devices... but it seems that the div element does not support the mouse events in Pocket IE, which would seem to be supported by this blog. But according to MSDN, the WinCE (which WinMo/PPC is based off of) version of IE does support these mouse events for some unknown list of elements. So can anyone tell me, are there any elements: img, a, span or whatever that support onmouse[down|move|up] in WinMo 6.5 Pocket IE? Thanks! If not, anyone have any other ideas for capturing a signature on a web page in Pocket IE?

  • Java: library that does nice formatted log outputs

    - by WizardOfOdds
    I cannot find back a library that allowed to format log output statements in a much nicer way than what is usually seen. One of the feature I remember is that it could 'offset' the log message depending on the 'nestedness' of where the log statement was occuring. That is, instead of this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java| 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java| 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java| 459 | Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java| 789 | Another debug message It would shows something like this: DEBUG | DefaultBeanDefinitionDocumentReader.java| 86 | Loading bean definitions DEBUG | AbstractAutowireCapableBeanFactory.java | 411 | Finished creating instance of bean 'MS-SQL' DEBUG | DefaultSingletonBeanRegistry.java | 213 | Creating shared instance of singleton bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 383 | Creating instance of bean 'MySQL' DEBUG | AutowireCapableBeanFactory.java | 459 | |__ Eagerly caching bean 'MySQL' to allow for resolving potential circular references DEBUG | AutowireCapableBeanFactory.java | 789 | |__ Another debug message This is an example I just made up (VeryLongCamelCaseClassNamesNotMine). But I remember seeing such cleanly formatted log output and they were really much nicer than anything I had seen before and, in addition to being just plain nicer, they were also easier to read for they reproduced some of the logical organization of the code. Yet I cannot find anymore what that library was. I'm pretty sure it was fully compatible with log4j or sl4j.

  • Using map/reduce for mapping the properties in a collection

    - by And
    Update: follow-up to MongoDB Get names of all keys in collection. As pointed out by Kristina, one can use Mongodb 's map/reduce to list the keys in a collection: db.things.insert( { type : ['dog', 'cat'] } ); db.things.insert( { egg : ['cat'] } ); db.things.insert( { type : [] }); db.things.insert( { hello : [] } ); mr = db.runCommand({"mapreduce" : "things", "map" : function() { for (var key in this) { emit(key, null); } }, "reduce" : function(key, stuff) { return null; }}) db[mr.result].distinct("_id") //output: [ "_id", "egg", "hello", "type" ] As long as we want to get only the keys located at the first level of depth, this works fine. However, it will fail retrieving those keys that are located at deeper levels. If we add a new record: db.things.insert({foo: {bar: {baaar: true}}}) And we run again the map-reduce +distinct snippet above, we will get: [ "_id", "egg", "foo", "hello", "type" ] But we will not get the bar and the baaar keys, which are nested down in the data structure. The question is: how do I retrieve all keys, no matter their level of depth? Ideally, I would actually like the script to walk down to all level of depth, producing an output such as: ["_id","egg","foo","foo.bar","foo.bar.baaar","hello","type"] Thank you in advance!

  • Capturing a NSParseErrorException

    - by Martin
    Could someone tell me how I can capture a NSParseErrorException? The Situation: my app downloads a small .plist file. I convert this into dictionary using the string method -propertylist. This normally works fine. I check for a connection before going to retrieve the file, so it works fine if I've got a connection to the internet, and works fine when I don't. However, I discovered a use case that crashes. If I'm at location that requires authetication before connecting to the internet (at Starbucks, say) what's being returned by the app isn't a plist and the attempt to parse it causes the application to crash. So is there a way to transform my code so that the NSParseErrorException is caught and rather than crashing the program I can just skip over this piece of code? NSDictionary *temp = [myDownloadString propertyList]; I tried doing this if ([myDownloadString propertyList]==NSParseErrorException){ //do something } but that didn't work.

  • RFC: Whitespace's Assembly Mnemonics

    - by Noctis Skytower
    Request For Comment regarding Whitespace's Assembly Mnemonics What follows in a first generation attempt at creating mnemonics for a whitespace assembly language. STACK ===== push number copy copy number swap away away number MATH ==== add sub mul div mod HEAP ==== set get FLOW ==== part label call label goto label zero label less label back exit I/O === ochr oint ichr iint In the interest of making improvements to this small and simple instruction set, this is a second attempt. hold N Push the number onto the stack copy Duplicate the top item on the stack copy N Copy the nth item on the stack (given by the argument) onto the top of the stack swap Swap the top two items on the stack drop Discard the top item on the stack drop N Slide n items off the stack, keeping the top item add Addition sub Subtraction mul Multiplication div Integer Division mod Modulo save Store load Retrieve L: Mark a location in the program call L Call a subroutine goto L Jump unconditionally to a label if=0 L Jump to a label if the top of the stack is zero if<0 L Jump to a label if the top of the stack is negative return End a subroutine and transfer control back to the caller exit End the program print chr Output the character at the top of the stack print int Output the number at the top of the stack input chr Read a character and place it in the location given by the top of the stack input int Read a number and place it in the location given by the top of the stack What is the general consensus on the following revised list for Whitespace's assembly instructions? They definitely come from thinking outside of the box and trying to come up with a better mnemonic set than last time. When the previous python interpreter was written, it was completed over two contiguous, rushed evenings. This rewrite deserves significantly more time now that it is the summer. Of course, the next version of Whitespace (0.4) may have its instructions revised even more, but this is just a redesign of what originally was done in a few hours. Hopefully, the instructions make more sense to those new to programming jargon.

  • Compiled Haskell libraries with FFI imports are invalid when imported into GHCI

    - by John Millikin
    I am using GHC 6.12.1, in Ubuntu 10.04 When I try to use the FFI syntax for static storage, only modules running in interpreted mode (ie GHCI) work properly. Compiled modules have invalid pointers, and do not work. I'd like to know whether anybody can reproduce the problem, whether this an error in my code or GHC, and (if the latter) whether it's a known issue. I'm using sys_siglist because it's present in a standard library on my system, but I don't believe the actual storage used matters (I discovered this while writing a binding to libidn). If it helps, sys_siglist is defined in <signal.h> as: extern __const char *__const sys_siglist[_NSIG]; I thought this type might be the problem, so I also tried wrapping it in a plain C procedure: #include<stdio.h> const char **test_ffi_import() { printf("C think sys_siglist = %X\n", sys_siglist); return sys_siglist; } However, importing that doesn't change the result, and the printf() call prints the same pointer value as show siglist_a. My suspicion is that it's something to do with static and dynamic library loading. Update: somebody in #haskell suggested this might be 64-bit specific; if anybody tries to reproduce it, can you mention your architecture and whether it worked in a comment? Code as follows: -- A.hs {-# LANGUAGE ForeignFunctionInterface #-} module A where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_a :: Ptr CString -- -- B.hs {-# LANGUAGE ForeignFunctionInterface #-} module B where import Foreign import Foreign.C foreign import ccall "&sys_siglist" siglist_b :: Ptr CString -- -- Main.hs {-# LANGUAGE ForeignFunctionInterface #-} module Main where import Foreign import Foreign.C import A import B foreign import ccall "&sys_siglist" siglist_main :: Ptr CString main = do putStrLn $ "siglist_a = " ++ show siglist_a putStrLn $ "siglist_b = " ++ show siglist_b putStrLn $ "siglist_main = " ++ show siglist_main peekSiglist "a " siglist_a peekSiglist "b " siglist_b peekSiglist "main" siglist_main peekSiglist name siglist = do ptr <- peekElemOff siglist 2 str <- maybePeek peekCString ptr putStrLn $ "siglist_" ++ name ++ "[2] = " ++ show str I would expect something like this output, where all pointer values identical and valid: $ runhaskell Main.hs siglist_a = 0x00007f53a948fe00 siglist_b = 0x00007f53a948fe00 siglist_main = 0x00007f53a948fe00 siglist_a [2] = Just "Interrupt" siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt" However, if I compile A.hs (with ghc -c A.hs), then the output changes to: $ runhaskell Main.hs siglist_a = 0x0000000040378918 siglist_b = 0x00007fe7c029ce00 siglist_main = 0x00007fe7c029ce00 siglist_a [2] = Nothing siglist_b [2] = Just "Interrupt" siglist_main[2] = Just "Interrupt"

  • Check if key is pressed using python (a daemon in the background)

    - by Nazarius Kappertaal
    I've created a python script in which an event needs to be executed each time I press the Super (or WinKey) on my keyboard. How can one achieve this without the python process being "focused" - as it is running in the background waiting for the key to be pressed to execute the event? I've seen a lot of posts around the web showing me how to read input - but they have all required one to have the process "focused" and none have showed me how to capture the Super (or WinKey) using a python script. I'm running Ubuntu 9.10.

  • Using trace and dbg in Erlang

    - by Gordon Guthrie
    I am trying to start using erlang:trace/3 and the dbg module to trace the behaviour of a live production system without taking the server down. The documentation is opaque (to put it mildly) and there don't appear to be any useful tutorials online. What I spent all day trying to do was capture what was happening in a particular function by trying to apply a trace to module:function using dbg:c and dbg:p but with no success at all... Does anyone have a succinct explanation of how to use trace in a live Erlang system?

  • PCAP Web Service Usage Logging for Dummies

    - by nick
    I've been assigned the task (for work) of working with PCAP for the first time in my life. I've read through the tutorials and have hacked together a real simple capture program which, it turns out, isn't that hard. However, making use of the data is more difficult. My goal is to log incomming and outgoing web service requests. Are there libraries (C or C++) that stitch together the packets from PCAP that would make reporting on this simple? Baring that is there something short of reading all of the RFC's from soup to nuts that will allow me to have an "ah-ha!" moment (all of the tutorials seem to stop at the raw packet level which isn't useful for me)? It looks like PERL has a library that may do this and I may eventually attempt a reverse engineer from PERL. NOTE BENE: Web Server logs aren't acceptable here as I will be intercepting on a routing device. If I had access to those I'd be done and happy...I don't.

  • How do you do dynamic script evaluation in C#?

    - by Deane
    What is the state of dynamic code evaluation in C#? For a very advanced feature of an app I'm working on, I'd like the users to be able to enter a line of C# code that should evaluate to a boolean. Something like: DateTime.Now.Hours > 12 && DateTime.Now.Hours < 14 I want to dynamically eval this string and capture the result as a boolean. I tried Microsoft.JScript.Eval.JScriptEvaluate, and this worked, but it's technically deprecated and it only works with Javascript (not ideal, but workable). Additionally, I'd like to be able to push objects into the script engine so that they can be used in the evaluation. Some resources I find mentioned dynamically compiling assemblies, but this is more overhead than I think I want to deal with. So, what is the state of dynamic script evaluation in C#? Is it possible, or am I out of luck?
