  • Best practice to pass a value from pop up control on iPad.

    - by Tattat
    It is an iPad app based on SDK 3.2. I have a MainUIView, that is subclass from UIView, it have a UIButton and a UILabel. When user press the UIButton, the pop up control will be appeared with a table view. When the user select a cell from the table view, the UILabel changes content base on the user click, and the pop up table view will disappear. The question is, how can I pass the "selected cell" to the UILabel. I am thinking making a "middle man" object. When the user click the UIButton, and the "middle man" will pass to the table. When the cell is selected, the "middle man" will store the idx, and call the UILabel change content from the value of "middle man". But I think it is pretty complex to implement, is there any easier way to implement it? thz u.

  • Why does RIGHT(@foostr, 0) return NULL when @foostr is varchar(max)?

    - by bob-montgomery
    In SQL Server 2005 If I want to find the right-most one character of a varchar(max) variable, no problem: declare @foostr varchar(max) set @foostr = 'abcd' select right (@foostr, 1) ---- d If I want to find the right-most zero characters of a string literal, no problem: select right ('abcd', 0) ------------------ It returns an empty string. If I want to find the right-most zero characters of a varchar(10), no problem: declare @foostr varchar(10) set @foostr = 'abcd' select right (@foostr, 0) ---- It returns an empty string. If I want to find the right-most zero characters of a varchar(max), well: declare @foostr varchar(max) set @foostr = 'abcd' select right (@foostr, 0) ---- NULL It returns NULL. Why?

  • C++ using cdb_read returns extra characters on some reads

    - by Moe Be
    Hi All, I am using the following function to loop through a couple of open CDB hash tables. Sometimes the value for a given key is returned along with an additional character (specifically a CTRL-P (a DLE character/0x16/0o020)). I have checked the cdb key/value pairs with a couple of different utilities and none of them show any additional characters appended to the values. I get the character if I use cdb_read() or cdb_getdata() (the commented out code below). If I had to guess I would say I am doing something wrong with the buffer I create to get the result from the cdb functions. Any advice or assistance is greatly appreciated. char* HashReducer::getValueFromDb(const string &id, vector <struct cdb *> &myHashFiles) { unsigned char hex_value[BUFSIZ]; size_t hex_len; //construct a real hex (not ascii-hex) value to use for database lookups atoh(id,hex_value,&hex_len); char *value = NULL; vector <struct cdb *>::iterator my_iter = myHashFiles.begin(); vector <struct cdb *>::iterator my_end = myHashFiles.end(); try { //while there are more databases to search and we have not found a match for(; my_iter != my_end && !value ; my_iter++) { //cerr << "\n looking for this MD5:" << id << " hex(" << hex_value << ") \n"; if (cdb_find(*my_iter, hex_value, hex_len)){ //cerr << "\n\nI found the key " << id << " and it is " << cdb_datalen(*my_iter) << " long\n\n"; value = (char *)malloc(cdb_datalen(*my_iter)); cdb_read(*my_iter,value,cdb_datalen(*my_iter),cdb_datapos(*my_iter)); //value = (char *)cdb_getdata(*my_iter); //cerr << "\n\nThe value is:" << value << " len is:" << strlen(value)<< "\n\n"; }; } } catch (...){} return value; }

  • How to return dynamic CSS with ASP.NET MVC?

    - by Morten Mertner
    I need a solution that lets me accomplish the following: Returning CSS that is dynamically generated by an action method Choosing CSS file depending on request parameter or cookie Using a tool to combine and compress (minify) CSS I am currently considering why there is no CssResult in ASP.NET MVC, and whether there might be a reason for its absence. Would creating a custom ActionResult not be the best way to go about this? Is there some other way that I've overlooked to do what I need? Any other suggestions or hints that might be relevant before I embark on this task will also be appreciated :)

  • MS Access 2007 - Property for text box to allow end-user to hit enter for return, not next

    - by Justin
    So I have a form that user's use for data entry, and on one form there is a text box there that is basically used. To enter notes. However, if the user hits i need the cursor to stay in that text box, and start a new line (uh....like word would)....but currently it is jumping to the next control (text box). So is there a simple property setting that would do the trick? Or a VBA method to accomplish? Thanks Justin

  • WPF - How do I style a row based on a binding property value?

    - by Nick
    Hey! So I am trying to bind a collection of objects (IList<) to a WPF datagrid. I would like to make the row background a different color if the 'artist' property is null or empty. I am checking the value stored at the property on the LoadingRow datagrid event. Currently my implementation seems to style all of the rows with an empty or null 'artist' property correctly. The problem is that is also styles the rows where the property is not null or empty in some cases. So some rows are given the red background even though the rows 'artist' property is not null. Can anyone tell me why this could be?? Here is the LoadingRow event: private void trackGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Track t = e.Row.DataContext as Track; if (String.IsNullOrEmpty(t.Artist)) { e.Row.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 125, 125)); } }

  • XPath: limit scope of result set

    - by Laramie
    Given the XML <a> <c> <b id="1" value="noob"/> </c> <b id="2" value="tube"/> <a> <c> <b id="3" value="foo"/> </c> <b id="4" value="goo"/> <b id="5" value="noob"/> <a> <b id="6" value="near"/> <b id="7" value="bar"/> </a> </a> </a> and the Xpath 1.0 query //b[@id=2]/ancestor::a[1]//b[@value="noob"] is there some way to limit the result set to the <b> elements that are ONLY the children of the immediate <a> element of the start node (//b[@id=2])? For example the Xpath above returns both node ids 1 and 5. The goal is to limit the result to just node id=1 since it is the only @value="noob" element in the same <c> group as our start node (//b[@id=2]). In English, "Starting at a node whose id is equal to 2, find all the elements whose value is "noob" that are descendants of the immediate parent c element without passing through another c element".

  • Do I need multiple template specializations if I want to specialize for several kinds of strings?

    - by romkyns
    For example: template<typename T> void write(T value) { mystream << value; } template<> void write<const char*>(const char* value) { write_escaped(mystream, value); } template<> void write<char*>(char* value) { write_escaped(mystream, value); } template<> void write<std::string>(std::string value) { write_escaped(mystream.c_str(), value); } This looks like I'm doing it wrong, especially the two variants for const and non-const char*. However I checked that if I only specialize for const char * then passing a char * variable will invoke the non-specialized version, when called like this in VC++10: char something[25]; strcpy(something, "blah"); write(something); What would be the proper way of doing this?

  • Flex DataGrid not Displaying Data

    - by asawilliams
    I have a custom dataGrid that acts more like a 2D list (if that makes sense at all). I am dynamically creating the columns and recreating the dataProvider to suit my needs. While debugging I can see that I am creating the columns and setting them to the dataGrid and creating and setting the dataProvider, but for some reason I am able to see the dataGrid and the columns but not the data. [Bindable] private var mockData:ArrayCollection = new ArrayCollection([ {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}, {value: "425341*"}]); ... <TwoDimensionalList width="100%" height="100%" numColumns="7" numRows="7" dataField="value" dataProvider="{mockData}"/> The snippet of code from the object only contains the important functions, everything else is not important (getters, setters, etc ...). While debugging I checked all the variables in the functions to make sure they were assigned and a value that I was expecting. [Snippet] public class TwoDimensionalList extends DataGrid { ... /** * Creates and sets properties of columns */ private function createColumns():void { var column:DataGridColumn; var cols:Array = this.columns; for(var i:uint=0; i < numColumns; i++) { column = new DataGridColumn("column"+i.toString()); column.dataField = "column"+i.toString(); cols[i]=column; } this.columns = cols; // go to the current gotoPage(this._currentPageNum); } /** * Sets the data for the dataprovider based on the * number of columns, rows, and page number. * * @param pageNum the page number of the data to be viewed in the DataGrids. */ private function gotoPage(pageNum:uint):void { _currentPageNum = pageNum; var startIndex:uint = (pageNum-1)*numColumns*numRows; var data:ArrayCollection = new ArrayCollection(); for(var i:uint=0; i < numRows; i++) { var obj:Object = new Object(); for(var j:uint=0; j < numColumns; j++) { if((i+(j*numRows)+startIndex) < _dataProvider.length) obj["column"+j.toString()] = String(_dataProvider.getItemAt(i+(j*numRows)+startIndex)["value"]); } data.addItem(obj); } this.dataProvider = data; } }

  • tk: how to invoke it just to display something, and return to the main program?

    - by max
    Sorry for the noob question but I really don't understand this. I'm using python / tkinter and I want to display something (say, a canvas with a few shapes on it), and keep it displayed until the program quits. I understand that no widgets would be displayed until I call tkinter.tk.mainloop(). However, if I call tkinter.tk.mainloop(), I won't be able to do anything else until the user closes the main window. I don't need to monitor any user input events, just display some stuff. What's a good way to do this without giving up control to mainloop? EDIT: Is this sample code reasonable: class App(tk.Tk): def __init__(self, sim): self.sim = sim # link to the simulation instance self.loop() def loop(): self.redraw() # update all the GUI to reflect new simulation state sim.next_step() # advance simulation another step self.after(0, self.loop) def redraw(): # get whatever we need from self.sim, and put it on the screen EDIT2 (added after_idle): class App(tk.Tk): def __init__(self, sim): self.sim = sim # link to the simulation instance self.after_idle(self.preloop) def preloop(): self.after(0, self.loop) def loop(): self.redraw() # update all the GUI to reflect new simulation state sim.next_step() # advance simulation another step self.after_idle(self.preloop) def redraw(): # get whatever we need from self.sim, and put it on the screen

  • [SCORM 2004] the cmi.total_time parameter does not return anything.

    - by Nephila
    I am programming a SCORM 2004 product. I can update the session_time, it works. I can set the status (passed, failed, etc...) I also can get the cmi.location time. No problems! But I don't succeed atingt get the total time (cmi.total_time). I have tested on 2 LMS: On Ganesha the API.GetValue('cmi.total_time') is an empty string. On Moodle the API.GetValue('cmi.total_time') is just a "P". I do have the correct logs with correct session times. EDIT. I also try on cloud.scorm.com and cmi.total_time returns each time PT0H0M0S.

  • Overloading Controller Actions

    - by DaveDev
    Hi Guys I was a bit surprised a few minutes ago when I tried to overload an Action in one of my Controllers I had public ActionResult Get() { return PartialView(/*return all things*/); } I added public ActionResult Get(int id) { return PartialView(/*return 1 thing*/); } .... and all of a sudden neither were working I fixed the issue by making 'id' nullable and getting rid of the other two methods public ActionResult Get(int? id) { if (id.HasValue) return PartialView(/*return 1 thing*/); else return PartialView(/*return everything*/); } and it worked, but my code just got a little bit ugly! Any comments or suggestions? Do I have to live with this blemish on my Controllers? Thanks Dave

Is this possible? How can I do it?

  • How to convert non key, value java arguments to applet params? (args like -Xmx64m)

  • I need to know inside of "while(fscanf != EOF){blah}" if the next fscanf is going to return EOF-- be

    - by Rancur3p1c
    I've got some code executing in a while(fscanf != EOF) loop. However, even when fscanf has finished executing, I need to keep running that code until some conditions are met. I mean I guess I could copy/paste the code to outside the while(fscanf) loop, and only use global variables, but that seems messy. Surely someone has encountered something like this before and has a cleaner solution.

  • How might I assume a "default value" when parsing using boost::spirit?

    - by tJener
    Let's say I have a grammar defined to something like: a b c d where c, and d are optional and default to 14 if not given. Can I get it to automatically return the 14 if the value isn't given? The closest I've come is like the following: qi::rule<Iterator, std::vector<int>(), ascii::space_type> some_rule; some_rule %= >> int_ >> int_ >> -int_ >> -int_; // ... some_other_rule = some_rule[&some_callback_for_int_vectors]; which will then get 0 for the optional values that didn't show up (I believe). I then change consecutive 0s at the end into 14. Not only is this horribly wrong, but its also just not elegant. Is there a better way to do this?
