  • Output iterator's value_type

    - by wilhelmtell
    The STL commonly defines an output iterator like so: template<class Cont> class insert_iterator : public iterator<output_iterator_tag,void,void,void,void> { // ... Why do output iterators define value_type as void? It would be useful for an algorithm to know what type of value it is supposed to output. For example, a function that translates a URL query "key1=value1&key2=value2&key3=value3" into any container that holds key-value strings elements. template<typename Ch,typename Tr,typename Out> void parse(const std::basic_string<Ch,Tr>& str, Out result) { std::basic_string<Ch,Tr> key, value; // loop over str, parse into p ... *result = typename iterator_traits<Out>::value_type(key, value); } The SGI reference page of value_type hints this is because it's not possible to dereference an output iterator. But that's not the only use of value_type: I might want to instantiate one in order to assign it to the iterator.

  • JPA - Setting entity class property from calculated column?

    - by growse
    I'm just getting to grips with JPA in a simple Java web app running on Glassfish 3 (Persistence provider is EclipseLink). So far, I'm really liking it (bugs in netbeans/glassfish interaction aside) but there's a thing that I want to be able to do that I'm not sure how to do. I've got an entity class (Article) that's mapped to a database table (article). I'm trying to do a query on the database that returns a calculated column, but I can't figure out how to set up a property of the Article class so that the property gets filled by the column value when I call the query. If I do a regular "select id,title,body from article" query, I get a list of Article objects fine, with the id, title and body properties filled. This works fine. However, if I do the below: Query q = em.createNativeQuery("select id,title,shorttitle,datestamp,body,true as published, ts_headline(body,q,'ShortWord=0') as headline, type from articles,to_tsquery('english',?) as q where idxfti @@ q order by ts_rank(idxfti,q) desc",Article.class); (this is a fulltext search using tsearch2 on Postgres - it's a db-specific function, so I'm using a NativeQuery) You can see I'm fetching a calculated column, called headline. How do I add a headline property to my Article class so that it gets populated by this query? So far, I've tried setting it to be @Transient, but that just ends up with it being null all the time.

  • php - disconnecting and connecting to multiple databases

    - by Phil Jackson
    Hi, I want to be able to switch from the current db to multiple dbs though a loop: $query = mysql_query("SELECT * FROM `linkedin` ORDER BY id", $CON ) or die( mysql_error() ); if( mysql_num_rows( $query ) != 0 ) { $last_update = time() / 60; while( $rows = mysql_fetch_array( $query ) ) { $contacts_db = "NNJN_" . $rows['email']; // switch to the contacts db mysql_select_db( $contacts_db, $CON ); $query = mysql_query("SELECT * FROM `linkedin` WHERE token = '" . TOKEN . "'", $CON ) or die( mysql_error() ); if( mysql_num_rows( $query ) != 0 ) { mysql_query("UPDATE `linkedin` SET last_update = '{$last_update}' WHERE token = '" . TOKEN . "'", $CON ) or die( mysql_error() ); }else{ mysql_query("INSERT INTO `linkedin` (email, token, username, online, away, last_update) VALUES ('" . EMAIL . "', '" . TOKEN . "', '" . USERNAME . "', 'true', 'false', '$last_update')", $CON ) or die( mysql_error() ); } } mysql_free_result( $query ); } // switch back to your own mysql_select_db( USER_DB, $CON ); It does insert and update details from the other databases but it also inserts and edits data from the current users database which I dont want. Any ideas?

  • going reverse in a for loop?

    - by sil3nt
    Hello there, Basically i got this for loop and i want the number inputed (eg. 123) to be printed out in reverse, so "321". so far it works fine and prints out the correct order when the for loop is for(i = 0; i<len ; i++) but i get an error when i try to print it in reverse?. Whats going wrong? #include <stdio.h> #include <string.h> void cnvrter(char *number); int main(){ char number[80]; printf("enter a number "); gets(number); cnvrter(number); return 0; } void cnvrter(char *number){ char tmp[80]; int i = 0,len = 0; int cnvrtd_digit = 0; len = strlen(number); printf("\nsize of input %d\n",len); for(i = len; i>len ; i--){ if ( ( number[i] >= '0' ) && ( number[i]<='9' ) ){ tmp[0] = number[i]; sscanf(tmp,"%d",&cnvrtd_digit); } printf("%d\n",cnvrtd_digit); } }

  • jitter if multiple outliers in ggplot2 boxplot

    - by Andreas
    I am trying to find a suitable display to illustrate various properties within and across school classes. For each class there is only 15-30 data points (pupils). Right now i am leaning towards a whisker-less boxplot, showing only 1.,2. and 3. quartile + datapoints more then e.g. 1 population SD +/- the sample median. This I can do. However - I need to show this graph to some teachers, in order to gauge what they like most. I'd like to compare my graph with a normal boxplot. But the normal boxplot looks the same if there is only one outlier, or e.g. 5 outliers at the same value. In this case this would be a deal-breaker. e.g. test <-structure(list(value = c(3, 5, 3, 3, 6, 4, 5, 4, 6, 4, 6, 4, 4, 6, 5, 3, 3, 4, 4, 4, 3, 4, 4, 4, 3, 4, 5, 6, 6, 4, 3, 5, 4, 6, 5, 6, 4, 5, 5, 3, 4, 4, 6, 4, 4, 5, 5, 3, 4, 5, 8, 8, 8, 8, 9, 6, 6, 7, 6, 9), places = structure(c(1L, 2L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 2L, 1L, 2L, 2L, 2L, 1L, 2L, 1L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 1L, 1L, 1L, 2L, 1L, 1L, 2L, 2L, 2L, 1L, 1L, 2L, 2L, 1L, 2L, 1L), .Label = c("a", "b"), class = "factor")), .Names = c("value", "places"), row.names = c(NA, -60L), class = "data.frame") ggplot(test, aes(x=places,y=value))+geom_boxplot() Here there are two outliers at ("a",9) - but only one "dot" shown. So my question: How to jitter the outliers. And - what kind of display would you suggest for this kind of data?

  • Confused over behavior of List.mapi in F#

    - by James Black
    I am building some equations in F#, and when working on my polynomial class I found some odd behavior using List.mapi Basically, each polynomial has an array, so 3*x^2 + 5*x + 6 would be [|6, 5, 3|] in the array, so, when adding polynomials, if one array is longer than the other, then I just need to append the extra elements to the result, and that is where I ran into a problem. Later I want to generalize it to not always use a float, but that will be after I get more working. So, the problem is that I expected List.mapi to return a List not individual elements, but, in order to put the lists together I had to put [] around my use of mapi, and I am curious why that is the case. This is more complicated than I expected, I thought I should be able to just tell it to make a new List starting at a certain index, but I can't find any function for that. type Polynomial() = let mutable coefficients:float [] = Array.empty member self.Coefficients with get() = coefficients static member (+) (v1:Polynomial, v2:Polynomial) = let ret = List.map2(fun c p -> c + p) (List.ofArray v1.Coefficients) (List.ofArray v2.Coefficients) let a = List.mapi(fun i x -> x) match v1.Coefficients.Length - v2.Coefficients.Length with | x when x < 0 -> ret :: [((List.ofArray v1.Coefficients) |> a)] | x when x > 0 -> ret :: [((List.ofArray v2.Coefficients) |> a)] | _ -> [ret]

  • MIDP 2.0 version issues: $method is undefined for $type

    - by Kilnr
    Hi, I've written a MIDlet that does several "advanced" things: fetching images from the web, resizing them, saving them on the phone, displaying them. This all works perfectly in the Nokia S60 3rd Edition FP1 emulator. This device has MIDP 2.0 and CLDC 1.1 support (also JSR75, which I need in order to save files). It also works as it should on the Nokia E71 (physical device). I then tried to run the MIDlet on several other emulators. One of them, the DefaultCldcJtwiPhone2 from the Java ME SDK 3.0, also claims MIDP 2.0 and CLDC 1.1 support. It doesn't have JSR75, which explains why "FileConnection can not be resolved to a type". This does not, however, explain why List.deleteAll(), String.equalsIgnoreCase(String) and a few others are undefined. The actual errors that I get: The method ceil(double) is undefined for the type Math The method deleteAll() is undefined for the type List The method equalsIgnoreCase(String) is undefined for the type String The method getWidth() is undefined for the type Displayable When I look at the MIDP 2.0 (i.e. JSR118) API (http://java.sun.com/javame/reference/apis/jsr118/), I can clearly see all of these methods being present, with the "since" tag being either MIDP 2.0 or CLDC 1.1. My question: why doesn't an emulator with MIDP 2.0 support have access to all MIDP 2.0 methods? Or alternatively, what am I doing wrong?

  • Access Denied while using System.Diagnostics.Process

    - by Mike C
    I am trying to use the unmanaged ImageMagick library in my ASP.NET application from the command line using System.Diagnostics.Process. Basically, users will upload an .eps file to the site, and then I will run the command line command to convert it into .jpg. This is the code I'm using to try and run the command: Dim proc As New System.Diagnostics.Process proc.StartInfo.RedirectStandardOutput = True proc.StartInfo.RedirectStandardError = True proc.StartInfo.FileName = "C:\Program Files (x86)\ImageMagick-6.6.1-Q16\convert.exe" proc.StartInfo.UseShellExecute = False proc.StartInfo.Arguments = String.Format("{0} {1}", Server.MapPath("~/logo/test.eps"), _ Server.MapPath("~/certificates/temp/test-1234.jpg")) proc.StartInfo.CreateNoWindow = True proc.Start() I am able to run this code just fine on our development Win 2k3 server, but not on our production Win 2k3 Server. I get the error "System.ComponentModel.Win32Exception: Access is denied". The main between the two servers is that the production is 64-bit and runs Plesk to manage multiple domains. I've tried adding rights asp.net user to the ImageMagick directory. The PS Admin says that in the case of Plesk, it's the same account that I use to access the site in VS using FPE. Does anyone know what I might do in order to allow this process to run on my production server? Thanks, Mike

  • kick off a map reduce job from my java/mysql webapp

    - by Brian
    Hi guys, I need a bit of archecture advice. I have a java based webapp, with a JPA based ORM backed onto a mysql relational database. Now, as part of the application I have a batch job that compares thousands of database records with each other. This job has become too time consuming and needs to be parallelized. I'm looking at using mapreduce and hadoop in order to do this. However, I'm not too sure about how to integrate this into my current architecture. I think the easiest initial solution is to find a way to push data from mysql into hadoop jobs. I have done some initial research on this and found the following relevant information and possibilities: 1) https://issues.apache.org/jira/browse/HADOOP-2536 this gives an interesting overview of some inbuilt JDBC support 2) This article http://architects.dzone.com/articles/tools-moving-sql-database describes some third party tools to move data from mysql to hadoop. To be honest I'm just starting out with learning about hbase and hadoop but I really don't know how to integrate this into my webapp. Any advice is greatly appreciated. cheers, Brian

  • How to invalidate cache when benchmarking?

UsingAs(values); ...Results to this: As: 0 : 322 When doing just this: UsingCast(values); ...Results to this: Cast: 0 : 322 Aside from running them independently, how to invalidate the cache so the second code being benchmarked won't receive the cached memory of first code? Benchmarking aside, just loved the fact that modern processors do this caching magic :-)

  • Java error on bilinear interpolation of 16 bit data

    - by Jon
    I'm having an issue using bilinear interpolation for 16 bit data. I have two images, origImage and displayImage. I want to use AffineTransformOp to filter origImage through an AffineTransform into displayImage which is the size of the display area. origImage is of type BufferedImage.TYPE_USHORT_GRAY and has a raster of type sun.awt.image.ShortInterleavedRaster. Here is the code I have right now displayImage = new BufferedImage(getWidth(), getHeight(), origImage.getType()); try { op = new AffineTransformOp(atx, AffineTransformOp.TYPE_BILINEAR); op.filter(origImage, displayImage); } catch (Exception e) { e.printStackTrace(); } In order to show the error I have created 2 gradient images. One has values in the 15 bit range (max of 32767) and one in the 16 bit range (max of 65535). Below are the two images 15 bit image 16 bit image These two images were created in identical fashions and should look identical, but notice the line across the middle of the 16 bit image. At first I thought that this was an overflow problem however, it is weird that it's manifesting itself in the center of the gradient instead of at the end where the pixel values are higher. Also, if it was an overflow issue than I would suspect that the 15 bit image would have been affected as well. Any help on this would be greatly appreciated.

  • NSScrollView frame and flipped documentView

    - by StrAbZ
    Hi, I have problems with NSScrollView, It is not displayed the way I want. Yes I know there is a lot of post about it around the web, I need to override the isFlipped, in order to make it return YES, in my NSView subclass. Ok, it's done, so now, my scrollView scroll from top to bottom, and not in the reverse way, as it was before overriding isFlipped. But, this is the second part, my real problem, which I didn't found any answer on the web, how the hell I'm supposed to code, or create my view in interface builder, if everything is flipped? If I put something at the top, it is displayed a the bottom… do you have any magic trick to handle that? And my last problem, is the NSScrollView frame. before setting the documentView of my scroll view, everything is fine, the scrollView is displayed at the place I choose, but, when I set the document view, it looks like the scrollview frame looks bigger, so I have to resize it…. is this a normal behavior? Thank you very much.

  • Python and MySQLdb

    - by rohanbk
    I have the following query that I'm executing using a Python script (by using the MySQLdb module). conn=MySQLdb.connect (host = "localhost", user = "root",passwd = "<password>",db = "test") cursor = conn.cursor () preamble='set @radius=%s; set @o_lat=%s; set @o_lon=%s; '%(radius,latitude,longitude) query='SELECT *, 6371*1000 * acos(cos(radians(@o_lat)) * cos(radians(lat)) * cos(radians(lon) - radians(@o_lon)) + sin(radians(@o_lat)) * sin(radians(lat))) as distance FROM poi_table HAVING distance < @radius ORDER BY distance ASC LIMIT 0, 50' complete_query=preamble+query results=cursor.execute (complete_query) print results The values of radius, latitude, and longitude are not important, but they are being defined when the script executes. What bothers me is that the snippet of code above returns no results; essentially meaning that the way that the query is being executed is wonky. I executed the SQL query (including the set variables with actual values, and it returned the correct number of results). If I modify the query to just be a simple SELECT FROM query (SELECT * FROM poi_table) it returns results. What is going on here?

  • Subquery max sequence number

    - by Andy Levesque
    I'm hesitant to ask because I'm sure it's out there, but I just can't seem to come up with the keywords to find the answer. I'm stepping outside my boundaries by starting with subqueries (normally an Access user). I have a query that has TECH_ID, SEQ_NBR, and PELL_FT_AWD_AMT SELECT ISRS_V_NEED_ANAL_RESULT_PARENT.TECH_ID, ISRS_V_NEED_ANAL_RESULT_PARENT.AWD_YR, ISRS_V_NEED_ANAL_RESULT_PARENT.PELL_FT_AWD_AMT, ISRS_V_NEED_ANAL_RESULT_PARENT.SEQ_NBR FROM ISRS_V_NEED_ANAL_RESULT_PARENT GROUP BY ISRS_V_NEED_ANAL_RESULT_PARENT.TECH_ID, ISRS_V_NEED_ANAL_RESULT_PARENT.AWD_YR, ISRS_V_NEED_ANAL_RESULT_PARENT.PELL_FT_AWD_AMT, ISRS_V_NEED_ANAL_RESULT_PARENT.SEQ_NBR HAVING (((ISRS_V_NEED_ANAL_RESULT_PARENT.AWD_YR)="2013")) ORDER BY ISRS_V_NEED_ANAL_RESULT_PARENT.TECH_ID; What I want to return is add a subquery that selects only the max SEQ_NUM for each record, but I can't seem to get the syntax right. In the past I would cheat and have a separate query that first gave me the TECH_ID and max SEQ_NUM, and then have a second query that use the original table and the first query in a join to get the rest. How can I do this in one query? Example: TECH_ID SEQ_NUM PELL 1 1 4000 1 2 4000 1 3 5000 Using just the max of the sequence number still returns: 1; 2; 4000 and 1; 3; 5000 when I'm only wanting the latter.

  • Aren't Information Expert / Tell Don't Ask at odds with Single Responsibility Principle?

    - by moffdub
    It is probably just me, which is why I'm asking the question. Information Expert, Tell Don't Ask, and SRP are often mentioned together as best practices. But I think they are at odds. Here is what I'm talking about: Code that favors SRP but violates Tell Don't Ask, Info Expert: Customer bob = ...; // TransferObjectFactory has to use Customer's accessors to do its work, // violates Tell Don't Ask CustomerDTO dto = TransferObjectFactory.createFrom(bob); Code that favors Tell Don't Ask / Info Expert but violates SRP: Customer bob = ...; // Now Customer is doing more than just representing the domain concept of Customer, // violates SRP CustomerDTO dto = bob.toDTO(); If they are indeed at odds, that's a vindication of my OCD. Otherwise, please fill me in on how these practices can co-exist peacefully. Thank you. Edit: someone wants a definition of the terms - Information Expert: objects that have the data needed for the operation should host the operation Tell Don't Ask: don't ask objects for data in order to do work; tell the objects to do the work Single Responsibility Principle: each object should have a narrowly defined responsibility

  • What is happening in this T-SQL code?

    - by Ben McCormack
    I'm just starting to learn T-SQL and could use some help in understanding what's going on in a particular block of code. I modified some code in an answer I received in a previous question, and here is the code in question: DECLARE @column_list AS varchar(max) SELECT @column_list = COALESCE(@column_list, ',') + 'SUM(Case When Sku2=' + CONVERT(varchar, Sku2) + ' Then Quantity Else 0 End) As [' + CONVERT(varchar, Sku2) + ' - ' + Convert(varchar,Description) +'],' FROM OrderDetailDeliveryReview Inner Join InvMast on SKU2 = SKU and LocationTypeID=4 GROUP BY Sku2 , Description ORDER BY Sku2 Set @column_list = Left(@column_list,Len(@column_list)-1) Select @column_list ---------------------------------------- 1 row is returned: ,SUM(Case When Sku2=157 Then Quantity Else 0 End) As [157 -..., SUM(Case ... The T-SQL code does exactly what I want, which is to make a single result based on the results of a query, which will then be used in another query. However, I can't figure out how the SELECT @column_list =... statement is putting multiple values into a single string of characters by being inside a SELECT statement. Without the assignment to @column_list, the SELECT statement would simply return multiple rows. How is it that by having the variable within the SELECT statement that the results get "flattened" down into one value? How should I read this T-SQL to properly understand what's going on?

  • Rails : fighting long http response times with ajax. Is it a good idea? Please, help with implementa

    - by baranov
    Hi, everybody! I've googled some tutorials, browsed some SO answers, and was unable to find a recipe for my problem. I'm writing a web site which is supposed to display almost realtime stock chart. Data is stored in constantly updating MySQL database, I wrote a find_by_sql query code which fetches all the data I need to get my chart drawn. Everything is ok, except performance - it takes from one second to one minute for different queries to fetch all the data from the database, this time includes necessary (My)SQL-server side calculations. This is simply unacceptable. I got the following idea: if the data is queried from the MySQL server one point a time instead of entire dataset, it takes only about 1-100ms to get an individual point. I imagine the data fetch process might be browser-driven. After the user presses the button in order to get a chart drawn, controller makes one request to the database and renders, say, a progress bar, say 1% ready. When the browser gets the response, it immediately makes an (ajax) request, and the server fetches the next piece of data and renders "2%". And so on, until all the data is ready and the server displays the requested chart. Could this be implemented in rails+js, is there a tutorial for solving a similar problem on the Web? I suppose if the thing is feasible at all, somebody should have already done this before. I have read several articles about ajax, I believe I do understand general principles, but never did nontrivial ajax programming myself. Thanks for your time!

  • Silverlight 4 seems like starving of memory

    - by Marco
    I have been playing a bit with Silverlight and try to port my Silverlight 3.0 application to Silverlight 4.0. My application loads different XAP files and upon a user request create an instance of a Xaml user control and adds it to the main container, in a sort of MEF approach in order I can have an extensible and pluggable application. The application is pretty huge and to keep acceptable the performances and the initial loading I have built up some helper classes to load in the background all pages and user controls that might be used later on. On Silverlight 3.0 everything was running smoothly without any problem so far. Switching to SL 4.0 I have noticed that when the process approaches to create the instances of the user controls the layout freezes unexpectedly for a minute and sometimes for more. Looking at the task manager the memory usage of IE jumps from 50MB to 400MB and sometimes up to 1.5 GB. If the process won't take that much the layout is rendered properly even though the memory usage is still extremely high. Otherwise everything crashes due to out of memory exception. Running the same application compiled in SL3, the memory used is about 200MB when all the usercontrols are loaded. Time spent to load the application in SL3 is about 10 seconds, while it takes up to 3 mins in SL4 There are no transparencies, no opacities set, no effects and animations in the layout. User controls are instantied on the fly and added or removed in the visual tree on purpose when the user switches from one screen to another. The resources are all cleaned properly when a usercontrol is removed from the visual tree to allow the GC to operate in the background. I may do something wrong but I could not figure out where exactly nail out the source of this problem. As far as I know there is no memory profiler in SL4 that can help me out to find where to look at. But again I could not be updated on new debugging tools available.

  • awk + sorting file according to values in the file and write two diffrent files

    hi I have in file file_test values of right eye and left eye How to separate the file_test to file1 and file2 by awk in order to write the equal values on file1 and different values on file2 as the following example down THX file_test: NAME: jim LAST NAME: bakker right eye: |5|< left eye VALUE: |5|< NAME: Jorg LAST NAME: mitchel right eye: |3|< left eye VALUE: |5|< NAME: jimmy LAST NAME: kartter right eye: |6|< left eye VALUE: |5|< NAME: david LAST NAME: kann right eye: |9|< left eye VALUE: |9|< file1: NAME: jim LAST NAME: bakker right eye: |5|< left eye VALUE: |5|< NAME: david LAST NAME: kann right eye: |9|< left eye VALUE: |9|< file2: NAME: Jorg LAST NAME: mitchel right eye: |3|< left eye VALUE: |5|< NAME: jimmy LAST NAME: kartter right eye: |6|< left eye VALUE: |5|<

  • java BufferedReader specific length returns NUL characters

    - by Bastien
    I have a TCP socket client receiving messages (data) from a server. messages are of the type length (2 bytes) + data (length bytes), delimited by STX & ETX characters. I'm using a bufferedReader to retrieve the two first bytes, decode the length, then read again from the same bufferedReader the appropriate length and put the result in a char array. most of the time, I have no problem, but SOMETIMES (1 out of thousands of messages received), when attempting to read (length) bytes from the reader, I get only part of it, the rest of my array being filled with "NUL" characters. I imagine it's because the buffer has not yet been filled. char[] bufLen = new char[2]; _bufferedReader.read(bufLen); int len = decodeLength(bufLen); char[] _rawMsg = new char[len]; _bufferedReader.read(_rawMsg); return _rawMsg; I solved the problem in several iterative ways: first I tested the last char of my array: if it wasn't ETX I would read chars from the bufferedReader one by one until I would reach ETX, then start over my regular routine. the consequence is that I would basically DROP one message. then, in order to still retrieve that message, I would find the first occurence of the NUL char in my "truncated" message, read & store additional characters one at a time until I reached ETX, and append them to my "truncated" messages, confirming length is ok. it works also, but I'm really thinking there's something I could do better, like checking if the total number of characters I need are available in the buffer before reading it, but can't find the right way to do it... any idea / pointer ? thanks !

  • Logical file not working for SUBFILE/SETLL?

    - by user1516536
    I'm using three logical file with different Record Format where on the first subfile I'm using LF1 and LF2 where on the first subfile I cannot use *LOVAL SETLL it will give me Run Time Error. not sure why? then the program will lead me to second subfile and I'm using LF3 it seems fine. but then If I back to first subfile the subfile turn to blanks.???? why? this my subroutine for building my subfile: C CLRSR BEGSR C EVAL *IN55='0' C WRITE USQLSCTL C EVAL *IN55='1' C ENDSR C* C*BUILDING SUBFILE C BLDSR BEGSR C *LOVAL SETLL USRLGX C EVAL RECNO=0 C EXSR TMISR1 C EXSR REDSR1 C DOW NOT %EOF C IF USRID<>IDD C EXSR MVESR C EXSR DIMSR C MOVE USRID IDD C EVAL RECNO=RECNO+1 C WRITE USQLS C ENDIF C EXSR TMISR1 C EXSR REDSR1 C ENDDO C ENDSR and the related subroutine C TMISR1 BEGSR C READ USRLGX C MOVE USRTI MINTI C ENDSR C REDSR1 BEGSR C READ USRLG C MOVE USRTO MAXTO C ENDSR 6 n the LF I used is USRLG and USRLGX. where both LF refer to the same record format. but each LF has different sorted order. *record format has been RENAME on F-Spec I have this two problem which is: I only can use *LOVAL setll logical-file once only. n the result for coding above sometime it will give result for UserTimeIn some time it equals to blanks.(000000)

  • using XSL to replace XML nodes with new nodes

    - by iHeartGreek
    I need an XSL solution to replace XML nodes with new nodes. Say I have the following existing XML structure: <root> <criteria> <criterion>AAA</criterion> </criteria> </root> And I want to replace the one criterion node with: <criterion>BBB</criterion> <criterion>CCC</criterion> <criterion>DDD</criterion> So that the final XML result is: <root> <criteria> <criterion>BBB</criterion> <criterion>CCC</criterion> <criterion>DDD</criterion> </criteria> </root> I have tried using substring-before and substring-after to just copy the first half of the structure, then just copy the second half (in order to fill in my new nodes in between the two halves) but it appears that the substring functions only recognize text in between the nodes' tags, and not the tags themselves like I want them to. :( :( Any other solutions?

  • Is it possible to store controls(Panel) as object, serialize it and store it as a file?

    - by ikky
    The topic says it all. Using Compact Framework C# I'm tiling (order/sequence is important) some images that i download from an url, into a Panel(each image is a PictureBox). This can be a huge process, and may take some time. Therefor i only want the user to download the images and tile them once. So the next time the user uses the Tile Application, the Panel that was created the first time is already stored in a file and is loaded from that file. So what i want is a method to store a Panel as a file. Is this possible, or do you think i should do it another way? I've tried something like this: BinaryWriter panelStorage = new BinaryWriter(new FileStream("imagePanel.panel", FileMode.OpenOrCreate, FileAccess.Write, FileShare.None)); Byte[] bImageObject = new Byte[20000]; bImageObject = (byte[])(object)this.imagePanel; panelStorage .Write(bMapObject); panelStorage .Close(); But the casting was not very legal :P "InvalidCastException" Can anyone help me with this problem? Thank you in advance!
