  • How can I synchronize one set of data with another?

    - by RenderIn
    I have an old database and a new database. The old records were converted to the new database recently. All our old applications continue to point to the old database, but the new applications point to the new database. Currently the old database is the only one being updated, so throughout the day the new database becomes out of sync. It is acceptable for the new database to be out of sync for a day, so until all our applications are pointed to the new database I just need to write a nightly cron job that will bring it up to date. I do not want to purge the new database and run the complete conversion script each night, as that would reduce uptime and would create a mess in our auditing of that table. I'm thinking about selecting all the data from the old database, converting it to the new database structure in memory, and then checking for the existence of each record before inserting it in the new database. After that's done, I'd select everything from the new database and check if it exists in the old one, and if not delete it. Is this the simplest way to do this?

  • Passing a string to a function in C++

    - by Chef Flambe
    I want to pass a string like "Celcius" into a function that I have but I keep getting errors tossed back at me from the Function. System::Console::WriteLine' : none of the 19 overloads could convert all the argument types I figure I just have something simple wrong. Can someone point out my mistake please? Using MS Visual C++ 2010 I've posted the offending code. The other functions (not posted) work fine. void PrintResult( double result, std::string sType ); // Print result and string // to the console //============================================================================================= // start of main //============================================================================================= void main( void ) { ConsoleKeyInfo CFM; // Program Title and Description ProgramDescription(); // Menu Selection and calls to data retrieval/calculation/result Print CFM=ChooseFromMenu(); switch(CFM.KeyChar) // ************************************************************ { //* case '1' : PrintResult(F2C(GetTemperature()),"Celsius"); //* break; //* //* case '2' : PrintResult(C2F(GetTemperature()),"Fahrenheit"); //* break; //* //* default : Console::Write("\n\nSwitch : Case !!!FAILURE!!!"); //* } //************************************************************ system("pause"); return; } //Function void PrintResult( double result, std::string sType ) { Console::WriteLine("\n\nThe converted temperature is {0:F2} degrees {1}\n\n",result,sType); return; }

  • Hiding Url for asp.net page

    - by user204588
    Hello, I'm creating an html page that is posted to another page for processing. I don't want users to see the weird URL they are redirected to and I was using FRAMES but I can't figure out how to add my HTML page dynamically because I need the variables and either add frames or try another way to accomplish this. So, based on how I'm creating the page below, how can I hide the URL and add something that I want. Here is how I'm creating the page. StringBuilder sb = new StringBuilder(); sb.Append("<html><head></head>"); sb.Append("<body onload=\"document.frmLaunch.submit();\">"); sb.Append("<form name=\"frmLaunch\" action=\"" + variableTargetURL + "\" method=\"post\">"); sb.Append("<input type=hidden name=\"testVariable\" value=\"" + variableTest + "\">"); sb.Append("</form>"); sb.Append("</body></html>"); HttpResponse response = HttpContext.Current.Response; response.Clear(); response.Write(sb.ToString()); response.End();

  • Low Throughput on Windows Named Pipe Over WAN

    - by MichaelB76
    I'm having problems with low performance using a Windows named pipe. The throughput drops off rapidly as the network latency increases. There is a roughly linear relationship between messages sent per second and round trip time. It seems that the client must ack each message before the server will send the next one. This leads to very poor performance, I can only send 5 (~100 byte) messages per second over a link with an RTT of 200 ms. The pipe is asynchronous, using multiple overlapped write operations (and multiple overlapped reads at the client end), but this is not improving throughput. Is it possible to send messages in parallel over a named pipe? The pipe is created using PIPE_TYPE_MESSAGE, would PIPE_READMODE_BYTE work better? Is there any other way I can improve performance? This is a deployed solution, so I can't simply replace the pipe with a socket connection (I've read that Windows named pipe aren't recommended for use over a WAN, and I'm wondering if this is why). I'd be grateful for any help with this matter.

  • jQuery: How do I rewrite .after( content, content )?

    - by Evan Carroll
    I've got this form working, but according to my previous question it might not be supported: it isn't in the docs either way -- but the intention is pretty obvious in the code. $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ) , $('<span>OEM</span>') /*Notice this (a second) argument */ ); What this does is insert <div class="little check"> with a simple .click() callback, followed by a sibling of <span>OEM</span>. How else can I write this then? I'm having difficulty conjuring something working by chaining any combination of .after(), and .insertAfter()? I would expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<div class="little check" />').click( function () { alert('hi') } ).after ( $('<span>OEM</span>') ) ); I would also expect this to work, but it doesn't: $(".section.warranty .warranty_checks :last").after( $('<span>OEM</span>').insertAfter( $('<div class="little check" />').click( function () { alert('hi') } ) ); );

  • How do I repeat function over several row.

    - by ChrisBD
    I'll admit that I'm not an Excel guru so maybe someone here can help me. On my worksheet I have several blocks of data. I calculate the sum of all items within column D of that block. Within each block I am checking the value of the cell in column C and if it contains the letter "y" and the value in column D of that row is equal to zero I must exclude the total sum of column D. Currently I am doing this by multiplying the sum value by either 1 or 0 which is produced by running a test over the cell contents. Below is an example of what I am using to test rows 23 to row 25 inclusively for data in Column D. I am also performing the same on Column E and G, but the "y" character is always in column C, hence the absolut column reference. =IF(AND($C23="y",D23=0),0,1)*IF(AND($C24="y",D24=0),0,1)*IF(AND($C25="y",D25=0),0,1) There must be a more efficient way to do this. Ideally I would like to write a function that I can paste into a cell and then select the rows or cells over which I run the test. Can anyone point me in the right direction?

  • Duplicate information from sql result

    - by puddleJumper
    I looked in about 18 other posts on here an most people are asking how to delete the records not just hide them. So my problem: I have a database with staff members who are associated with locations. Many of the staff members are associated with more than one location. What I want to do is to only display the first location listed in the mysql result and skip over the others. I have the sql query linking the tables together and it works aside from it showing the same information for those staff members that are in those other locations multiple times so example would be like this: This is the sql statement I have currently SELECT staff_tbl.staffID, staff_tbl.firstName, staff_tbl.middleInitial, staff_tbl.lastName, location_tbl.locationID, location_tbl.staffID, officelocations_tbl.locationID, officelocations_tbl.officeName, staff_title_tbl.title_ID, staff_title_tbl.staff_ID, titles_tbl.titleID, titles_tbl.titleName FROM staff_tbl INNER JOIN location_tbl ON location_tbl.staffID = staff_tbl.staffID INNER JOIN officelocations_tbl ON location_tbl.locationID = officelocations_tbl.locationID INNER JOIN staff_title_tbl ON staff_title_tbl.staff_ID = staff_tbl.staffID INNER JOIN titles_tbl ON staff_title_tbl.title_ID = titles_tbl.titleID and my php is <?php do { ?> <tr> <td><?php echo $row_rs_Staff_Info['firstName']; ?>&nbsp; <?php echo $row_rs_Staff_Info['lastName']; ?></td> <td><?php echo $row_rs_Staff_Info['titleName']; ?>&nbsp; </td> <td><?php echo $row_rs_Staff_Info['officeName']; ?>&nbsp; </td> </tr> <?php } while ($row_mysqlResult = mysql_fetch_assoc($rs_mysqlResult)); ?> What I would like to know is there a way using php to select only the first entry listed for each person and display that and just skip over the other two. I was thinking it could be done by possibly adding the staffID's to an array and if they are in there to skip over the next one listed in the staff_title_tbl but wasn't quite sure how to write it that way. Any help would be great thank you in advance.

  • Determining presence of prototype with correct return type

    - by R..
    Here's a random problem in C black magic I just came up with: Write a function that returns 1 if malloc has been prototyped to return a pointer type and 0 if malloc has a return type of int (either implicitly or due to wrong prototype), without invoking any implementation-defined or undefined behavior. I believe it's solvable, but I haven't worked out the solution. Note that calling the function cannot be necessary and in fact is not possible since calling a function with the incorrect prototype is undefined behavior. I have some ideas for ingredients but I think it makes for a better puzzle (and possibly more diverse ideas) if I leave them out for now. I don't need the solution for any immediate use, but it could be handy in configure scripts and such. Update: A better example of the usefulness (with strdup instead of malloc): #undef strdup #define strdup(x) (strdup_has_proto ? strdup((x)) : my_strdup((x))) i.e. being able to implement X_has_proto as an expression at the source level could be a portable way to use functions which a system might or might not have, and fall back on a local replacement, without needing any separate configure step.

  • Sending arbitrarily long string over Java TCP socket

    - by bibismcbryde
    I have an Android app that communicates over a TCP socket with a server I wrote. The method I'm using now to read and write output works fine for smaller strings (up to 60kB) but I get an exception thrown when the string is much longer than that. Here is the relevant part of what I have for the server and client: Server: DataInputStream dis = null; DataOutputStream dos = null; try { dis = new DataInputStream(server.getInputStream()); dos = new DataOutputStream(server.getOutputStream()); String input = ""; input = dis.readUTF(); handle_input info = new handle_input(input, id); String xml = info.handle(); dos.writeUTF(xml); server.close(); } Client: Socket socket = null; DataOutputStream dos = null; DataInputStream dis = null; Boolean result; try { socket = new Socket(ip, port); dos = new DataOutputStream(socket.getOutputStream()); dis = new DataInputStream(socket.getInputStream()); dos.writeUTF(the_text); String in = ""; while (in.equals("")) { in += dis.readUTF(); } } How can I modify it to deal with potentially enormous Strings? I've been looking around and can't seem to find a clear answer. Thanks.

  • Changing style sheets depending on useragent

    - by John Vasiliou
    <script language="Javascript"> var deviceIphone = "iPhone"; var deviceIpod = "iPod"; //Initialize our user agent string to lower case. var uagent = navigator.userAgent.toLowerCase(); //************************** // Detects if the current device is an iPhone. function DetectiPhone() { if (uagent.search(deviceIphone) > -1) {document.write('<link rel="stylesheet" type="text/css" href="ui/mobile/css/site.css">'); } etc... Above is the start of my code. I am trying to change the CSS file depending on what platform the user is using. I currently use media="screen ... " but it doesn't work with the amount of platforms I'm trying to use. I need something a lot more detailed/complex that is why I'm turning to useragents. Any ideas why the css file doesn't change on my iPhone using the above code? Better yet, any ideas on another way to change style sheets depending on the users platform/screen resolution?

  • ListView and wrap_content

    - by gaiapac
    I want to create an activity with a ListView on the left and a TextView on the right, side by side. I write the following xml, but the ListView occupies the entire page and it don't worry about the wrap_content. Why? How can I resolve it? <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <ListView android:id="@+id/lv" android:layout_width="wrap_content" android:layout_height="match_parent" /> <TextView android:id="@+id/tv" android:layout_width="wrap_content" android:layout_height="match_parent" /> </LinearLayout> EDIT: my onCreate @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ListView lv = (ListView) findViewById(R.id.lv); String[] values = new String[] { "Test1", "Test2", "Test3", "Test4" }; ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,R.layout.left, R.id.tv1, values); lv.setAdapter(adapter); }

  • Create a new site programmatically and select parent site? (SharePoint)

    - by peter
    Hi, I am using the following code to create a new site: newWeb = SPContext.GetContext(HttpContext.Current).Web.Webs.Add(newSiteUrl, newSiteName, null, (uint)1033, siteTemplate, true, false); try { newWeb.Update(); } NewSiteUrl and newSiteName are values from two textboxes and on whichever site I use this code (in a web part) the new site will be a subsite to this site. I would now like to be able to select a parent site so that the new site can sit anywhere in the site collection, not just as a subsite to the site where I use the web part. I created the following function to get all the sites in the site collection and populate a drop down with the name and url for every site private void getSites() { SPSite oSiteCollection = SPContext.Current.Site; SPWebCollection collWebsite = oSiteCollection.AllWebs; for (int i = 0; i < collWebsite.Count; i++) { ddlParentSite.Items.Add(new ListItem(collWebsite[i].Title, collWebsite[i].Url)); } oSiteCollection.Dispose(); } If the user selects a site in the dropdown, is it possible to use that URL in newSiteUrl so decide where the new site should be? I don't get it to work really and the new site still becomes a subsite to the current one. I guess it has to do with HttpContext.Current? Any ideas on how I should do it instead? It's the first time I write custom web parts and the sharepoint object model is a bit overwhelming at the moment. Thanks in advance.

  • Coding the R-ight way - avoiding the for loop

    - by mropa
    I am going through one of my .R files and by cleaning it up a little bit I am trying to get more familiar with writing the code the r-ight way. As a beginner, one of my favorite starting points is to get rid of the for() loops and try to transform the expression into a functional programming form. So here is the scenario: I am assembling a bunch of data.frames into a list for later usage. dataList <- list (dataA, dataB, dataC, dataD, dataE ) Now I like to take a look at each data.frame's column names and substitute certain character strings. Eg I like to substitute each "foo" and "bar" with "baz". At the moment I am getting the job done with a for() loop which looks a bit awkward. colnames(dataList[[1]]) [1] "foo" "code" "lp15" "bar" "lh15" colnames(dataList[[2]]) [1] "a" "code" "lp50" "ls50" "foo" matchVec <- c("foo", "bar") for (i in seq(dataList)) { for (j in seq(matchVec)) { colnames (dataList[[i]])[grep(pattern=matchVec[j], x=colnames (dataList[[i]]))] <- c("baz") } } Since I am working here with a list I thought about the lapply function. My attempts handling the job with the lapply function all seem to look alright but only at first sight. If I write f <- function(i, xList) { gsub(pattern=c("foo"), replacement=c("baz"), x=colnames(xList[[i]])) } lapply(seq(dataList), f, xList=dataList) the last line prints out almost what I am looking for. However, if i take another look at the actual names of the data.frames in dataList: lapply (dataList, colnames) I see that no changes have been made to the initial character strings. So how can I rewrite the for() loop and transform it into a functional programming form? And how do I substitute both strings, "foo" and "bar", in an efficient way? Since the gsub() function takes as its pattern argument only a character vector of length one.

  • Use of Java [Interfaces / Abstract classes]

    - by Samuel
    Hello, Lately i decided to take a look at Java so i am still pretty new to it and also to the approach of OO programming, so i wanted to get some things straight before learning more, (i guess it's never to soon to start with good practices). I am programming a little 2D game for now but i think my question applies to any non trivial project. For the simplicity i'll provide examples from my game. I have different kinds of zombies, but they all have the same attributes (x, y, health, attack etc) so i wrote an interface Zombie which i implement by WalkingZombie, RunningZombie TeleportingZombie etc. Is this the best thing to do? Am i better of with an abstract class? Or with a super class? (I am not planning to partially implement functions - therefor my choice for an interface instead of an abstract class) I have one class describing the main character (Survivor) and since it is pretty big i wanted to write an interface with the different functions, so that i can easily see and share the structure of it. Is it good practice? Or is it simply a waste of space and time? I hope this question will not be rated as subjective because i thought that experienced programmers won't disagree about this kind of topic since the use of interfaces / super classes / abstract classes follows logical rules and is thereby not simply a personal choice. Thank you for your time -Samuel

  • Change cookies when doing jQuery.ajax requests in Chrome Extensions

    - by haskellguy
    I have wrote a plugin for facebook that sends data to testing-fb.local. The request goes through if the user is logged in. Here is the workflow: User logs in from testing-fb.local Cookies are stored When $.ajax() are fired from the Chrome extension Chrome extension listen with chrome.webRequest.onBeforeSendHeaders Chrome extension checks for cookies from chrome.cookies.get Chrome changes the Set-Cookies header to be sent And the request goes through. I wrote this part of code that shoud be this: function getCookies (callback) { chrome.cookies.get({url:"https://testing-fb.local", name: "connect.sid"}, function(a){ return callback(a) }) } chrome.webRequest.onBeforeSendHeaders.addListener( function(details) { getCookies(function(a){ // Here something happens }) }, {urls: ["https://testing-fb.local/*"]}, ['blocking']); Here is my manifest.json: { "name": "test-fb", "version": "1.0", "manifest_version": 1, "description": "testing", "permissions": [ "cookies", "webRequest", "tabs", "http://*/*", "https://*/*" ], "background": { "scripts": ["background.js"] }, "content_scripts": [ { "matches": ["http://*.facebook.com/*", "https://*.facebook.com/*"], "exclude_matches" : [ "*://*.facebook.com/ajax/*", "*://*.channel.facebook.tld/*", "*://*.facebook.tld/pagelet/generic.php/pagelet/home/morestories.php*", "*://*.facebook.tld/ai.php*" ], "js": ["jquery-1.8.3.min.js", "allthefunctions.js"] } ] } In allthefunction.js I have the $.ajax calls, and in background.js is where I put the code above which however looks not to run.. In summary, I have not clear: What I should write in Here something happens If this strategy is going to work Where should I put this code?

  • Stream buffering issue

    - by Kolyunya
    The mod_rewrite documentation states that it is a strict requirement to disable in(out)put buffering in a rewrite program. Keeping that in mind I've written a simple program (I do know that it lacks the EOF check but this is not an issue and it saves one condition check per loop): #include <stdio.h> #include <stdlib.h> int main ( void ) { setvbuf(stdin,NULL,_IOLBF,4200); setvbuf(stdout,NULL,_IOLBF,4200); int character; while ( 42 ) { character = getchar(); if ( character == '-' ) { character = '_'; } putchar(character); } return 42 - 42; } After making some measurements I was shocked - it was over 9,000 times slower than the demo Perl script provided by the documentation: #!/usr/bin/perl $| = 1; # Turn off I/O buffering while (<STDIN>) { s/-/_/g; # Replace dashes with underscores print $_; } Now I have two related questions: Question 1. I believe that the streams may be line buffered since Apache sends a new line after each path. Am I correct? Switching my program to setvbuf(stdin,NULL,_IOLBF,4200); setvbuf(stdout,NULL,_IOLBF,4200); makes it twice as fast as Perl one. This should not hit Apache's performance, should it? Question 2. How can one write a program in C which will use unbuffered streams (like Perl one) and will perform as fast as Perl one?

  • Sorting a very large text file in Java

    - by Alice
    Hi, I have a large text file I need to sort in Java. The format is: word [tab] frequency [new line] The algorithm for sorting is: Read some of the file, filtering for purlely alphabetic words. Once you have X number of alphabetic words, call Collections.sort and write the result to a file. Repeat until you have finished reading the file. Start reading two sorted files, comparing line by line for the word with higher frequency, and writing at the same time to a new file as to not load much into your memory Repeat until all files are merged into one large file Right now I've divided the large file into smaller ones (sorted by descending frequency) with 10,000 lines each. I know I need to somehow merge these files back together, but I'm not sure how to go about this. I've created a LinkedList to keep track of all the files created. The algorithm says to compare each line in the two files, except I've tried a case where , say file1 = 8,6,5,3,1 and file2 = 9,8,8,8,8. Then if I compare them line by line I would get file3 = 9,8,8,6,8,5,8,3,8,1 which is incorrectly sorted (they should be in decreasing order). I think I'm misunderstanding some part of the algorithm. If someone could point out what I should do instead, I'd greatly appreciate it. Thanks. edit: Yes this is an assignment. We aren't allowed to increase memory unfortunately :(

  • Good C++ array class for dealing with large arrays of data in a fast and memory efficient way?

    - by Shane MacLaughlin
    Following on from a previous question relating to heap usage restrictions, I'm looking for a good standard C++ class for dealing with big arrays of data in a way that is both memory efficient and speed efficient. I had been allocating the array using a single malloc/HealAlloc but after multiple trys using various calls, keep falling foul of heap fragmentation. So the conclusion I've come to, other than porting to 64 bit, is to use a mechanism that allows me to have a large array spanning multiple smaller memory fragments. I don't want an alloc per element as that is very memory inefficient, so the plan is to write a class that overrides the [] operator and select an appropriate element based on the index. Is there already a decent class out there to do this, or am I better off rolling my own? From my understanding, and some googling, a 32 bit Windows process should theoretically be able address up to 2GB. Now assuming I've 2GB installed, and various other processes and services are hogging about 400MB, how much usable memory do you think my program can reasonably expect to get from the heap? I'm currently using various flavours of Visual C++.

  • getting string.substring(N) not to choke when N > string.length

    - by aape
    I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have dim s as string = someStream.readline a = s.substring(10, 5) b = s.substring(16, 5) c = s.substring(22, 5) because it'll choke when it substrings past the length of the string. I know I could test the length of the string before processing each row, and I have automated the filling of some of the vsariables using a counter and a loop, and using the counter*theWidthOfTheGivenVariable to jump around, but this project was a dog to start with (come on! turning a report into a spreadsheet?), but there are many different types of rows (it's not just a grid), and the code's getting ugly fast. I'd like this to be clean, clear, and maintainable for the poor sucker that gets this after me. If it matters, here's my code so far (it's really crufty at the moment). You can see some of my/its idiocy in the processSection#data subs So, I'm wondering 1) is there a way baked in to .NET to have string.substring not error when reading past the end of a string without wrapping it in a try...catch? and 2) would it be appropriate in this situation to write a new string class that inherits from string that has a more friendly substring function in it? ETA: Thanks for all the advice and knowledge everyone. I'll go with the extension. Hopefully one of these years, I'll get my chops up enough to pay someone back in kind. :)

  • I want a function to return a type of the subclass its invoked from

    - by Jay
    I want to have a function defined in a superclass that returns a value of the type of the subclass that is used to invoke the function. That is, say I have class A with a function plugh. Then I create subclasses B and C that extend A. I want B.plugh to return a B and C.plugh to return a C. Yes, they could return an A, but then the caller would have to either cast it to the right subtype, which is a pain when used a lot, or declare the receiving variable to be of the supertype, which loses type safety. So I was trying to do this with generics, writing something like this: class A<T extends A> { private T foo; public T getFoo() { return foo; } } class B extends A<B> { public void calcFoo() { foo=... whatever ... } } class C extends A<C> { public void calcFoo() { foo=... whatever ... } } This appears to work but it looks pretty ugly. For one thing, I get warnings on "class A". The compiler says that A is generic and I should specify the type. I guess it wants me to say "class A". But what would I put in for x? I think I could get stuck in an infinite loop here. It seems weird to write "class B extends A", but this causes no complaints, so maybe that's just fine. Is this the right way to do it? Is there a better way?

  • Problem monitoring directory for file activity in VB.net 2010...

    - by Mike Cialowicz
    I'm trying to write a simple program to monitor a folder for new files in VB.NET 2010, and am having some trouble. Here's a simplified version of what my program looks like: Imports System.IO Public Class Main Public fileWatcher As FileSystemWatcher Sub btnGo_Click(sender As System.Object, e As System.EventArgs) Handles btnGo.Click '//# initialize my FileSystemWatcher to monitor a particular directory for new files fileWatcher = New FileSystemWatcher() fileWatcher.Path = thisIsAValidPath.ToString() fileWatcher.NotifyFilter = NotifyFilters.FileName AddHandler fileWatcher.Created, AddressOf fileCreated fileWatcher.EnableRaisingEvents = True End Sub Private Sub fileCreated(sender As Object, e As FileSystemEventArgs) '//# program does not exit when I comment the line below out txtLatestAddedFilePath.Text = e.FullPath '//# e.FullPath is valid when I set a breakpoint here, but when I step into the next line, the program abruptly halts with no error code that I can see End Sub End Class As you can see, I have a button which will initialize a FileSystemWatcher when clicked. The initialization works, and when I place a new file in the monitored directory, the program reaches the fileCreated sub. I can even see that e.FullPath is set correctly. However, it exits abruptly right after that with no error code (none that I can see, anyways). If I comment everything in the fileCreated sub out, the program continues running as expected. Any ideas as to why it's dying on me? Any help would be greatly appreciated. I'm fairly new to VS/VB.NET, so maybe I'm just making a silly mistake. Thanks!

'MyApp.VM.MyClassVM.CtrId.get' must declare a body because it is not marked abstract or extern Any info on what I'm doing wrong will be greatly appreciated.

  • Nested IF statements in Excel [Over the 7 allowed limit]

    - by Alks
    hey guys, i am trying to create a spreadsheet which automagically gives a grade to a student based on their marks they got. I've apparently hit excels nested IF statement limit which is 7. here's my if statement: =IF(O5>0.895,"A+",IF(O5>0.845,"A",IF(O5>0.795,"A-",IF(O5>0.745,"B+",IF(O5>0.695,"B",IF(O5>0.645,"B-",IF(O5>0.595,"C+",IF(O5>0.545,"C","D")))))))) I was reading online that I could create a VBA script and assign it that, but I dont know anything about VBA....so if someone could help me write a VBA for this, would be awesome. Its still mising the C- grade and anything lower should be awarded a D mark. This is the grading scheme I am trying to create...: A+ 89.500 - 100.000 Pass with Distinction A 84.500 - 89.490 Pass with Distinction A- 79.500 - 84.490 Pass with Distinction B+ 74.500 - 79.490 Pass with Merit B 69.500 - 74.490 Pass with Merit B- 64.500 - 69.490 Pass with Merit C+ 59.500 - 64.490 Pass C 54.500 - 59.490 Pass C- 49.500 - 54.490 Pass D 0.000 - 49.490 Specified Fail I wouldn't mind going down the VBA route, however my understanding of VB language is absolutely minimal (don't like it)...if this gets too tedious, I was thinking to create a small php/mysql application instead. Cheers :)

  • Why do you program? Why do you do what you do? [closed]

    - by Pirate for Profit
    To me, writing a new program is like a puzzle. Before you write any code for a large system, you have to carefully craft each piece in your mind and imagine how all the pieces will fit together. If you don't, your solution may end up being undefined. What I mean is, I often don't know what I'm doing so I'll come to this site and beg for a code snippet, and then somehow try to hack it into my projects. I started writing GW-Basic when I was around 8 years old. Then it progressed from there, went to california university and did some Python and C++, but really didn't learn anything(college = highsk00l++). I've mostly been self-taught, took awhile to break bad habits and I'd say only in recent years would I consider myself understanding of design patterns and all that stuff (no but honestly procedural dudes, I would not want to design and maintain a large system procedurally, yous crazy). And despite my username, money has NOT been a big motivator. I've gone from job to job, I can usually get the work done perfect very quickly, any delays on my part are understandable (well about as understandable as it gets in the industry). But I ain't gonna work for peanuts because I got mouths to feed. Why do you program? Why do you do what you do?

  • Foreach loop and tasks.

    - by Scott Chamberlain
    I know from the codeing guidlines that I have read you should not do for (int i = 0; i < 5; i++) { Task.Factory.StartNew(() => Console.WriteLine(i)); } Console.ReadLine(); as it will write 5 5's, I understand that and I think i understand why it is happening. I know the solution is just to do for (int i = 0; i < 5; i++) { int localI = i; Task.Factory.StartNew(() => Console.WriteLine(localI)); } Console.ReadLine(); However is something like this ok to do? foreach (MyClass myClass in myClassList) { Task.Factory.StartNew(() => myClass.DoAction()); } Console.ReadLine(); Or do I need to do the same thing I did in the for loop. foreach (MyClass myClass in myClassList) { MyClass localMyClass = myClass; Task.Factory.StartNew(() => localMyClass.DoAction()); } Console.ReadLine();
