  • C# Dynamic IF Else Statment [closed]

    - by Tan Liang Liang
    allrowcol[i] = rowcol + "||"; Is it possible to put : if (loop == allrowcol.ToString()) If not, how can I place a few values inside an if statement? I need to have a few values in the if, and this value is generated from a text file. e.g. if(loop==11||14||15||16") My array for the allrowcol.ToString() is "11||14||15||16||". rowcol is the number that I extract from my text file. But my if (read as a whole string). What can I do?

  • How to get a dynamic attribute name in cfloop over query in ColdFusion

    - by Kip
    I'm inside a cfloop over a query. I want to get an attribute, but I won't know what that attribute will be until runtime. Using #qryResult[MyAttr]# fails with the error "Complex object types cannot be converted to simple values." What is the syntax for doing this? Here is a simplified example: <cfquery datasource="TestSource" name="qryResult"> SELECT * FROM MyTable </cfquery> <cfloop query="qryResult"> <cfset MyAttr="autoid" /> <cfoutput> Test 1: #qryResult.autoid# <br/> <!--- succeeds ---> Test 2: #qryResult[MyAttr]# <br/> <!--- fails ---> </cfoutput> </cfloop>

  • Programming Windows Cluster resource DLLs using Delphi

    - by kaeff
    I wonder whether there's a way to program a resource DLL for Windows Clusters in Delphi. I want to write a program that observes cluster state changes. Judging from the MSDN API reference, all relevant functions are located in the ClusAPI.h and ResAPI.h headers, but unfortunately it seems as if they haven't been ported yet and HeaderConv seems to fail on them. Does anyone has experience in doing such a thing?

  • C# recursive programming with lists

    - by David Torrey
    I am working on a program where each item can hold an array of items (i'm making a menu, which has a tree-like structure) currently i have the items as a list, instead of an array, but I don't feel like I'm using it to its full potential to simplify code. I chose a list over a standard array because the interface (.add, .remove, etc...) makes a lot of sense. I have code to search through the structure and return the path of the name (i.e. Item.subitem.subsubitem.subsubsubitem). Below is my code: public class Item { //public Item[] subitem; <-- Array of Items public List<Item> subitem; // <-- List of Items public Color itemColor = Color.FromArgb(50,50,200); public Rectangle itemSize = new Rectangle(0,0,64,64); public Bitmap itemBitmap = null; public string itemName; public string LocateItem(string searchName) { string tItemName = null; //if the item name matches the search parameter, send it up) if (itemName == searchName) { return itemName; } if (subitem != null) { //spiral down a level foreach (Item tSearchItem in subitem) { tItemName = tSearchItem.LocateItem(searchName); if (tItemName != null) break; //exit for if item was found } } //do name logic (use index numbers) //if LocateItem of the subitems returned nothing and the current item is not a match, return null (not found) if (tItemName == null && itemName != searchName) { return null; } //if it's not the item being searched for and the search item was found, change the string and return it up if (tItemName != null && itemName != searchName) { tItemName.Insert(0, itemName + "."); //insert the parent name on the left --> TopItem.SubItem.SubSubItem.SubSubSubItem return tItemName; } //default not found return null; } } My question is if there is an easier way to do this with lists? I've been going back and forth in my head as to whether I should use lists or just an array. The only reason I have a list is so that I don't have to make code to resize the array each time I add or remove an item.

  • Dynamic URL to Stay the Same on all Pages

    - by JCBiggar
    so when my url looks like this: http://mywebsitehere.com/?kw=1 I am using this code below to do stuff with it: <?php if( isset($_GET['kw'] )){ //my div here } ?> It works great, and I am getting exactly what I want on the page. However, any link I click on that page will change the url structure and remove the ?kw=1 . Is there anyway to add the ?kw=1 to every link for that session? I have no clue how to do this? Any ideas or answers would be great! Thanks! Let me know if I need to give more to my question.

  • TSQL Writing into a Temporary Table from Dynamic SQL

    - by Jeff
    Consider the following code: SET @SQL1 = 'SELECT * INTO #temp WHERE ...' exec(@SQL1) SELECT * from #temp (this line throws an error that #temp doesn't exist) Apparently this is because the exec command spins off a separate session and #temp is local to that session. I can use a global temporary table ##temp, but then I have to come up with a naming scheme to avoid collisions. What do you all recommend?

  • calling a function from a set of overloads depending on the dynamic type of an object

    - by Jasper
    I feel like the answer to this question is really simple, but I really am having trouble finding it. So here goes: Suppose you have the following classes: class Base; class Child : public Base; class Displayer { public: Displayer(Base* element); Displayer(Child* element); } Additionally, I have a Base* object which might point to either an instance of the class Base or an instance of the class Child. Now I want to create a Displayer based on the element pointed to by object, however, I want to pick the right version of the constructor. As I currently have it, this would accomplish just that (I am being a bit fuzzy with my C++ here, but I think this the clearest way) object->createDisplayer(); virtual void Base::createDisplayer() { new Displayer(this); } virtual void Child::createDisplayer() { new Displayer(this); } This works, however, there is a problem with this: Base and Child are part of the application system, while Displayer is part of the GUI system. I want to build the GUI system independently of the Application system, so that it is easy to replace the GUI. This means that Base and Child should not know about Displayer. However, I do not know how I can achieve this without letting the Application classes know about the GUI. Am I missing something very obvious or am I trying something that is not possible?

  • Programming CLI Commands in Program [C / LINUX]

    - by Blackbinary
    I am attempting to make a program in C which presents a GUI and allows the user to select from a list of applications, which to install on the computer. I can manage the gui, but I've never been taught how to actually issue command line commands. I know with bash its just apt-get install firefox for example, but how do I do such a thing with C? i.e. on click, the program runs 'apt-get install The other problem is I'm not familiar with the proper name for this interaction, so it is hard to search. Thanks for the help

  • Socket Programming : Inputstream Stuck in loop - read() always return 0

    - by Atom Skaa ska Hic
    Server side code public static boolean sendFile() { int start = Integer.parseInt(startAndEnd[0]) - 1; int end = Integer.parseInt(startAndEnd[1]) - 1; int size = (end - start) + 1; try { bos = new BufferedOutputStream(initSocket.getOutputStream()); bos.write(byteArr,start,size); bos.flush(); bos.close(); initSocket.close(); System.out.println("Send file to : " + initSocket); } catch (IOException e) { System.out.println(e.getLocalizedMessage()); disconnected(); return false; } return true; } Client Side public boolean receiveFile() { int current = 0; try { int bytesRead = bis.read(byteArr,0,byteArr.length); System.out.println("Receive file from : " + client); current = bytesRead; do { bytesRead = bis.read(byteArr, current, (byteArr.length-current)); if(bytesRead >= 0) current += bytesRead; } while(bytesRead != -1); bis.close(); bos.write(byteArr, 0 , current); bos.flush(); bos.close(); } catch (IOException e) { System.out.println(e.getLocalizedMessage()); disconnected(); return false; } return true; } Client side is multithreading,server side not use multithreading. I just paste some code that made problem if you want see all code please tell me. After I debug the code, I found that if I set max thread to any and then the first thread always stuck in this loop. That bis.read(....) always return 0. Although, server had close stream and it not get out of the loop. I don't know why ... But another threads are work correctly. do { bytesRead = bis.read(byteArr, current, (byteArr.length-current)); if(bytesRead >= 0) current += bytesRead; } while(bytesRead != -1);

  • Creating a Dynamic calendar in Silverlight

    - by Tom
    I am attempting to create a long range calendar that dynamically loads (and unloads) event data as the user scrolls left or right through time. I'm really struggling to figure out how to lay the basic framework of the UI out and how to dynamically build the interface as the user scrolls by clicking and dragging the mouse in the view area. See the image below for a basic diagram of the intent. Each slice would have potentially multiple rectangles in it for events that occurred on that day (slice). I would like each slice to be a canvas to allow me to position those rectangles appropriately. There are a few problems that I am not yet sure how to tackle but this is the first big one that I've been mulling over for a while and can't quite wrap my head around: I know how to dynamically create controls but how would I go about adding things to one end of the scrollable content while removing things from the other depending on the way the user is scrolling? Any guidance in the right direction would be much appreciated! Thanks.

  • Socket Programming for the Web

    - by Benny
    I have to interact with a legacy system that accepts socket communication and messages. My goal is to make the application cross-platform, but I need the ability to push messages to the client (i.e. - .NET's WCF, Java's Comet) and detect when the user closes out of their browser to destroy the socket. I have built a prototype of .NET wrapper + WCF + Silverlight but it is so disconnected it is difficult to manage the state of the user and seems to be a nightmare to support. All of that considered, what would be my best option?

  • Dynamic content in a Gridview

    - by mariki
    I have a gridview with couple of columns,I want to achieve the following: If user is NOT authorized display normal columns. If user IS authorized: set mouseover event for first column text and display some buttons (that are not available for NOT authorized users) in a second column when user hover over(using javascript) the first column. I am have 2 difficulties: The first one where and when should I create the buttons? I have 2 options, I can create those button on design time, in gridviews template and just set Visible value to false and then in codebehind set it to true if user is authorized. The second option would be creating this buttons dynamically in gridview_RowCreated event (or any other event) if user is authorized. The Second difficulty is setting the javascript event to show the buttons, the event should be added only if user is authorized! Note that event and buttons should have some kind of id match for Javascript function to know what should it hide/unhide when event is triggered. What should I do, what is the best practice? I know this is a long question, but please try to help :)

  • How to understand the programming of an operating system

    - by piemesons
    Hello, I want to learn the operating system. How it works. I don't want to make my own operating system. I just want to learn how it works. As I can find out source code of any open source OS. But how to start. Like starting from the first elementary kernel (whatever it is). Somebody suggested I try to implement Linux from scratch etc. Please guide me in a proper way. I want to know about the proper path to follow. I am ready to invest three to four years just to understand the basics. I have good fundamentals of C, C++, PHP, OOP and compiler design.

  • Nested Dynamic PHP Class

    - by user338844
    Alright, I may just need a terminology update, but I have been playing in Magento and Joomla, and they do references like $mage = new Mage; $mage->block('blockname'); where class Mage through some process I am failing to figure out is calling: class blockname extends something{ } Don't quote me on that code, however I am looking to do something like that where I have a file that I can do $myscript-block('blockname'); and it will load and call the file with class blockname. I hope that is not too confusing, but any help is appreciated. Thanks in advance!

  • Javascript function programming — receiving elaborate parameters

    - by Barney
    I'm writing a Javascript function that would manipulate an array written on-the-fly and sent as a parameter. The function is written as follows: function returnJourney(animation,clean){ var properties = {}; // loads of other inane stuff for(i in animation[0]) properties[animation[0][i]] = animation[0].i; // heaps more inane stuff } The animation in question is a set of parameters for a jQuery animation. Typically it takes the format of ({key:value,key:value},speedAsInteger,modifierAsString). So to kick off initial debugging I call it with: returnJouney(({'foo':'bar'},3000),1); And straight off the bat things are way off. As far as I see it this would have returnJourney acknowledge clean === 1, and animation being an array with an object as its first child and the number 3000 as its second. Firebug tells me animation evaluates as the number 3000. What am I doing wrong?

  • c++ programming for clusters and HPC

    - by Abruzzo Forte e Gentile
    HI All I need to write a scientific application in C++ doing a lot of computations and using a lot of memory. I have part of the job but due to high requirements in terms of resources I was thinking to start moving to OpenMPI. Before doing that I have a simple curiosity: If I understood the principle of OpenMPI is the developer that has the task of splitting the jobs over different nodes calling SEND and RECEIVE based on node available at that time. Do you know if it does exist some library or OS or whatever that has this capability letting my code reamain as it is now? Basically something that connects all computers and let share as one their memory and CPU? I am a bit confused because of the high material available on the topic. Should I look at cloud computing? or Distributed Shared Memory? Can you help me or address me a bit? Thanks

  • Jquery Quicksearch plugin issue with dynamic pages

    Quicksearch is really cool... but it has a usability issue that makes it behave weird. A lot of users presses enter after inserting a string so the page is reloaded with no parameters and the queries are destroyed. look at that: http://www.parksmania.it/parco_list.php?rid=1 Adding $('form#filtroRapido').submit(function () { return false; }); doesn't work! Has someone already solved this?
