  • Are there C# controls that can be used to create a hierarchical list of prioritised items?

    - by Mendokusai
    I need to be able to display and edit a hierarchical list of tasks in a C# app. It can either be a Windows form app, or ASP.NET. Basically, I want similar behaviour to the way Microsoft Project handles tasks. The control would need to: 1) Maintain a list of items made up of several fields 2) Each item can have a number of children (at least 3 levels of nesting) 3) It needs to be very easy to change the parents/children of an item 4) It needs to be very easy to edit the fields (as fast as changing cells in Excel) 5) It needs to be very easy to reorder the items by dragging and dropping or cut and paste 6) If I can easily connect the control to a database, even better Before I go and create something manually, I'm wondering if there is something available already?

  • How to overwrite an array of char pointers with a larger list of char pointers?

    - by Casey
    My function is being passed a struct containing, among other things, a NULL terminated array of pointers to words making up a command with arguments. I'm performing a glob match on the list of arguments, to expand them into a full list of files, then I want to replace the passed argument array with the new expanded one. The globbing is working fine, that is, g.gl_pathv is populated with the list of expected files. However, I am having trouble copying this array into the struct I was given. #include <glob.h> struct command { char **argv; // other fields... } void myFunction( struct command * cmd ) { char **p = cmd->argv; char* program = *p++; // save the program name (e.g 'ls', and increment to the first argument glob_t g; memset(&g, 0, sizeof(g)); g.gl_offs = 1; int res = glob(*p++, GLOB_DOOFFS, NULL, &g); glob_handle_res(res); while (*p) { res = glob(*p, GLOB_DOOFFS | GLOB_APPEND, NULL, &g); glob_handle_res(res); } if( g.gl_pathc <= 0 ) { globfree(&g); } cmd->argv = malloc((g.gl_pathc + g.gl_offs) * sizeof *cmd->argv); if (cmd->argv == NULL) { sys_fatal_error("pattern_expand: malloc failed\n");} // copy over the arguments size_t i = g.gl_offs; for (; i < g.gl_pathc + g.gl_offs; ++i) cmd->argv[i] = strdup(g.gl_pathv[i]); // insert the original program name cmd->argv[0] = strdup(program); ** cmd->argv[g.gl_pathc + g.gl_offs] = 0; ** globfree(&g); } void command_free(struct esh_command * cmd) { char ** p = cmd->argv; while (*p) { free(*p++); // Segfaults here, was it already freed? } free(cmd->argv); free(cmd); } Edit 1: Also, I realized I need to stick program back in there as cmd-argv[0] Edit 2: Added call to calloc Edit 3: Edit mem management with tips from Alok Edit 4: More tips from alok Edit 5: Almost working.. the app segfaults when freeing the command struct Finally: Seems like I was missing the terminating NULL, so adding the line: cmd->argv[g.gl_pathc + g.gl_offs] = 0; seemed to make it work.

  • ordered list does not work on IE7 (<ol><li).

    - by Cesar Lopez
    Hi all, I am trying to create an ordered list on IE7 but for some reason does not work. Does anybody knows why this can be? Thanks. eg. <ol> <li></li> <li><li> <ol> Update As an example I saw this page where if you look at it on IE7 you wont see de numbers, but if you look at it on any other (but not ie) you will see the numbers. http://www.arraystudio.com/as-workshop/make-ol-list-start-from-number-different-than-1-using-css.html Thanks

  • C: getopt with list of acceptable optarg. What is the best practise ?

    - by Xavier Maillard
    Hi, I am writing a C program which is a frontend to a myriad tools. This fronted will be launched like this: my-frontend --action <AN ACTION> As all the tools have the same prefix, let say for this example this prefix is "foo". I want to concatenate "AN ACTION" to this prefix and exec this (if the tool exists). I have written something but my implementation uses strcmp to test that "AN ACTION" is a valid action. Even if this works, I do not like it. So I am looking for a nicer solution that would do the same. The list of possibilities is pretty small (less than 10) and static (the list is "hardcoded") but I am sure there is a more "C-ish" way to do this (using a struct or something like that). As I am not a C expert, I am asking for your help. Regards

  • jquery: adding class on to list-items only on mouseover-remove on mouse-out?

    - by user239831
    hey guys, what's the best way to do that: i have a list <ul> <li>hello</li> <li>good bye</li> <li>arrivederci</li> <li class="selected">dude</li> <li>whatever</li> </ul> Initially one item already has a class of .selected applied. When i hover over one of the list-items i want this one to have the .selected class. So every item should only have the class applied when im over, as soon as i leave the item the class get's removed and the next one has the class.

  • How to get null when use head funtion with a empty list in cypher?

    - by PeaceMaker
    I have a cypher query like this. START dep=node:cities(city_code = "JGS"), arr=node:cities(city_code = "XMN") MATCH dep-[way:BRANCH2BRANCH_AIRWAY*0..1]->()-->arr RETURN length(way), transfer.city_code, extract(w in way: w.min_consume_time) AS consumeTime The relationship named "way" is a optional one, so the property named "consumeTime" will be a empty list when the relationship "way" not exsit. The query result is: | 0 | "JGS" | [] | | 1 | "SZX" | [3600] | When I want to use the head function with the property "consumeTime", it return a error "Invalid query: head of empty list". How can I get a result like this? | 0 | "JGS" | null | | 1 | "SZX" | 3600 |

  • Hibernate: how to maintain insertion order

    - by jwaddell
    I have a list of entities where creation order is important, but they do not contain a timestamp to use for sorting. Entities are added to the end of the list as they are created so they will be ordered correctly in the list itself. After persisting the list using Hibernate the entities appear in the database table in the order that they were created. However when retrieving the list using a new Hibernate session the list is now in reverse order of insertion/creation. Is this expected behaviour? Is there any way to retrieve the list in the same order as it appears in the table? The primary key is a UUID, and the list of entities should always have been created on the same IP address and JVM. This mean sorting by UUID is a possibility but I'd rather not make assumptions. Another possibility is if the list is guaranteed to always come out in reverse order I could always just work through it backwards.

  • Find common nodes from two linked lists using recursion

    - by Dan
    I have to write a method that returns a linked list with all the nodes that are common to two linked lists using recursion, without loops. For example, first list is 2 - 5 - 7 - 10 second list is 2 - 4 - 8 - 10 the list that would be returned is 2 - 10 I am getting nowhere with this.. What I have been think of was to check each value of the first list with each value of the second list recursively but the second list would then be cut by one node everytime and I cannot compare the next value in the first list with the the second list. I hope this makes sense... Can anyone help?

  • How to update a sharepoint list item via web services using a where clause?

    - by JL
    I would like to update a list item using SharePoint and am stuggling to find 1 decent CAML example. Here is what I want to do, in SQL my query would look something like this update [table] set field='value' where fieldID = id; so this would mean I have 1 item in a list I would like to update 1 field on given the ID of that listitem. I've tried this, but it doesn't work: batchElement.InnerXml = "<Method ID='1' Cmd='Update'>" + "<Field Name='DeliveryStatus'>" + newStatus.ToString() + "</Field>" + "<Where><Eq><FieldRef Name='ID' /><Value Type='Text'>" + id + "</Value></Eq></Where></Method>";

  • [FreeBSD kernel ]How to maintain a linked list on kernel lever?

    - by Andy Leman
    The situation is: I will implement sets of new system calls. Each of them need to access (read or write) a linked list. So, that means I will have several C programs. So, how can I maintain a linked list in memory and let several programs access it? Or,this is wrong....I should save it as a file? (but I hardly think this is a good idea).. A lot of confused questions here...Need help. Thank you indeed!

  • How to update only certain items in a list when using MVC?

    - by Eugen
    I'm building a GUI that includes a list with quite a lot of items. I allow the user to add/delete/edit those items. Up until now my update method called in the controller implied an entire JList reset (with its obvious performance issues). Now that there are hundreds of items available, updating the entire list is not fezable any longer. Does anyone know of a tutorial or can share an example (I haven't found any to suit my needs so far) in which the JList is updated something like JList.update(startIndex, endIndex);? Thanks for taking the time to answer.

  • How do I get a list of all languages that my Windows Forms application has been localized to?

    - by Andrei B
    I have localized localized a Form into two language by setting the Localizable property to True and setting the Language from (Default) to (Dutch(Netherlands)), and I changed the control texts. Visual Studio generated the resource files and compiles them into the application. I need to get a simple list of all the languages that my form has been localized into. Currently it would be just two English and Dutch, but more may come. I need to programatically get a list of "what languages my application is localized into". Do I look into the resource files or use ResourceManager or what? Thanks!
