    - by ChrisMuench
    I'm using the table adapter in C# where visual studio generates the code for you. I have inserts and updates working just fine using the following code. However when trying to delete using the .update it gives me the following error. Update requires a valid DeleteCommand when passed DataRow collection with deleted rows. this.workersTableAdapter.Update(this.nursery_dbDataSet_workers.workers);

  • Uneditable file and Unreadable(for further processing) file( WHY? ) after processing it through C++

    - by mgj
    Hi...:) This might look to be a very long question to you I understand, but trust me on this its not long. I am not able to identify why after processing this text is not being able to be read and edited. I tried using the ord() function in python to check if the text contains any Unicode characters( non ascii characters) apart from the ascii ones.. I found quite a number of them. I have a strong feeling that this could be due to the original text itself( The INPUT ). Input-File: Just copy paste it into a file "acle5v1.txt" The objective of this code below is to check for upper case characters and to convert it to lower case and also to remove all punctuations so that these words are taken for further processing for word alignment #include<iostrea> #include<fstream> #include<ctype.h> #include<cstring> using namespace std; ifstream fin2("acle5v1.txt"); ofstream fin3("acle5v1_op.txt"); ofstream fin4("chkcharadded.txt"); ofstream fin5("chkcharntadded.txt"); ofstream fin6("chkprintchar.txt"); ofstream fin7("chknonasci.txt"); ofstream fin8("nonprinchar.txt"); int main() { char ch,ch1; fin2.seekg(0); fin3.seekp(0); int flag = 0; while(!fin2.eof()) { ch1=ch; fin2.get(ch); if (isprint(ch))// if the character is printable flag = 1; if(flag) { fin6<<"Printable character:\t"<<ch<<"\t"<<(int)ch<<endl; flag = 0; } else { fin8<<"Non printable character caught:\t"<<ch<<"\t"<<int(ch)<<endl; } if( isalnum(ch) || ch == '@' || ch == ' ' )// checks for alpha numeric characters { fin4<<"char added: "<<ch<<"\tits ascii value: "<<int(ch)<<endl; if(isupper(ch)) { //tolower(ch); fin3<<(char)tolower(ch); } else { fin3<<ch; } } else if( ( ch=='\t' || ch=='.' || ch==',' || ch=='#' || ch=='?' || ch=='!' || ch=='"' || ch != ';' || ch != ':') && ch1 != ' ' ) { fin3<<' '; } else if( (ch=='\t' || ch=='.' || ch==',' || ch=='#' || ch=='?' || ch=='!' || ch=='"' || ch != ';' || ch != ':') && ch1 == ' ' ) { //fin3<<" '; } else if( !(int(ch)>=0 && int(ch)<=127) ) { fin5<<"Char of ascii within range not added: "<<ch<<"\tits ascii value: "<<int(ch)<<endl; } else { fin7<<"Non ascii character caught(could be a -ve value also)\t"<<ch<<int(ch)<<endl; } } return 0; } I have a similar code as the above written in python which gives me an otput which is again not readable and not editable The code in python looks like this: #!/usr/bin/python # -*- coding: UTF-8 -*- import sys input_file=sys.argv[1] output_file=sys.argv[2] list1=[] f=open(input_file) for line in f: line=line.strip() #line=line.rstrip('.') line=line.replace('.','') line=line.replace(',','') line=line.replace('#','') line=line.replace('?','') line=line.replace('!','') line=line.replace('"','') line=line.replace('?','') line=line.replace('|','') line = line.lower() list1.append(line) f.close() f1=open(output_file,'w') f1.write(' '.join(list1)) f1.close() the file takes ip and op at runtime.. as: python punc_remover.py acle5v1.txt acle5v1_op.txt The output of this file is in "acle5v1_op.txt" now after processing this particular output file is needed for further processing. This particular file "aclee5v1_op.txt" is the UNREADABLE Aand UNEDITABLE File that I am not being able to use for further processing. I need this for Word alignment in NLP. I tried readin this output with the following program #include<iostream> #include<fstream> using namespace std; ifstream fin1("acle5v1_op.txt"); ofstream fout1("chckread_acle5v1_op.txt"); ofstream fout2("chcknotread_acle5v1_op.txt"); int main() { char ch; int flag = 0; long int r = 0; long int nr = 0; while(!(fin1)) { fin1.get(ch); if(ch) { flag = 1; } if(flag) { fout1<<ch; flag = 0; r++; } else { fout2<<"Char not been able to be read from source file\n"; nr++; } } cout<<"Number of characters able to be read: "<<r; cout<<endl<<"Number of characters not been able to be read: "<<nr; return 0; } which prints the character if its readable and if not it doesn't print them but I observed the output of both the file is blank thus I could draw a conclusion that this file "acle5v1_op.txt" is UNREADABLE AND UNEDITABLE. Could you please help me on how to deal with this problem.. To tell you a bit about the statistics wrt the original input file "acle5v1.txt" file it has around 3441 lines in it and around 3 million characters in it. Keeping in mind the number of characters in the file you editor might/might not be able to manage to open the file.. I was able to open the file in gedit of Fedora 10 which I am currently using .. This is just to notify you that opening with a particular editor was not actually an issue at least in my case... Can I use scripting languages like Python and Perl to deal with this problem if Yes how? could please be specific on that regard as I am a novice to Perl and Python. Or could you please tell me how do I solve this problem using C++ itself.. Thank you...:) I am really looking forward to some help or guidance on how to go about this problem....

    I write the following code all the time to handle when the enter key pressed: $("#selectorid").keypress(function (e) { if (e.keyCode == 13) { var targetType = e.originalTarget ? e.originalTarget.type.toLowerCase() : e.srcElement.tagName.toLowerCase(); if (targetType != "textarea") { e.preventDefault(); e.stopPropagation(); // code to handler enter key pressed } } }); Is there a way to extend jQuery so that I could just write: $("#selectorid").enterKeyPress(fn);

  • Get preferences in AppWidget Provider

    - by Brian515
    Hi all, I seem to be having trouble reading preferences from my AppWidgetProvider class. My code works in an Activity, but it does not in an AppWidgetProvider. Here is the code I am using to read back a boolean: SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0); boolean autoreplyon = settings.getBoolean("autoreplyon", false); However, I get the "The method getSharedPreferences(String, int) is undefined for the type widget" error (widget is the name of my AppWidgetProvider class). Thanks in advance for any suggestions!

  • Shake to open view modally

    - by Vivas
    Hi, I have my 'shake' working fine (using motionEnded), based off of Apple's GLPaint code. When the user shakes the device (running 3.0 and up) I want to open a view controller modally using presentModalViewController. In my appdelegate I have the notification (as per the GLPaint sample code): [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(shakeToOpenHiddenScreen) name:@"shake" object:nil]; In my shakeToOpenHiddenScreen I just want to open view 'x' modally but I don't think that my appdelegate will respond to presentModalViewController. Is there a way around this?

    Is there an application similar to Java's Checkstyle for Python? By which I mean, I tool that analyzes Python code, and can be run as part of continuous integration (e.g. CruiseControl or Hudson). After analyzing it should produce an online accessible report which outlines any problems found in the code. Thank you,

  • is there difference between debug and release reference path while compiling?

    - by Nair
    I am building a SL3 + RIA application in VS2008. When compiled the application in debug mode it compiles fine with out any error, but when I compile the same application with out any code change in release mode I get an error 'The type of namespace name 'BusyIndicator' does not exist in the namespace 'System.Windows.Controls' (are you missing an assembly reference). All the errors are coming from the generated code name.g.cs Just curious anyone run into this problem.

  • Fleunt NHibernate not working outside of nunit test fixtures

    - by thorkia
    Okay, here is my problem... I created a Data Layer using the RTM Fluent Nhibernate. My create session code looks like this: _session = Fluently.Configure(). Database(SQLiteConfiguration.Standard.UsingFile("Data.s3db")) .Mappings( m => { m.FluentMappings.AddFromAssemblyOf<ProductMap>(); m.FluentMappings.AddFromAssemblyOf<ProductLogMap>(); }) .ExposeConfiguration(BuildSchema) .BuildSessionFactory(); When I reference the module in a test project, then create a test fixture that looks something like this: [Test] public void CanAddProduct() { var product = new Product {Code = "9", Name = "Test 9"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); using (ISession session = OrmHelper.OpenSession()) { var fromDb = session.Get<Product>(product.Id); Assert.IsNotNull(fromDb); Assert.AreNotSame(fromDb, product); Assert.AreEqual(fromDb.Id, product.Id); } My tests pass. When I open up the created SQLite DB, the new Product with Code 9 is in it. the tables for Product and ProductLog are there. Now, when I create a new console application, and reference the same library, do something like this: Product product = new Product() {Code = "10", Name = "Hello"}; IProductRepository repository = new ProductRepository(); repository.AddProduct(product); Console.WriteLine(product.Id); Console.ReadLine(); It doesn't work. I actually get pretty nasty exception chain. To save you lots of head aches, here is the summary: Top Level exception: An invalid or incomplete configuration was used while creating a SessionFactory. Check PotentialReasons collection, and InnerException for more detail.\r\n\r\n The PotentialReasons collection is empty The Inner exception: The IDbCommand and IDbConnection implementation in the assembly System.Data.SQLite could not be found. Ensure that the assembly System.Data.SQLite is located in the application directory or in the Global Assembly Cache. If the assembly is in the GAC, use element in the application configuration file to specify the full name of the assembly. Both the unit test library and the console application reference the exact same version of System.Data.SQLite. Both projects have the exact same DLLs in the debug folder. I even tried copying SQLite DB the unit test library created into the debug directory of the console app, and removed the build schema lines and it still fails If anyone can help me figure out why this won't work outside of my unit tests it would be greatly appreciated. This crazy bug has me at a stand still.

  • Converting non-generic List type to Generic List type in Java 1.5

I want to create a List<ObjectType> based on the incoming List object so that my calling code is talking to List<ObjectType>. What's the best way to convert the List (or any other object collection) to a List<ObjectType>.

  • What is the difference between these Pentium Extreme Edition CPUs?

    - by Giffyguy
    The CPU in question is the Pentium Extreme Edition 955. Intel's website shows four "versions", but for the most part they all look identical. They even share the same set of ordering codes. But one of them has a substantially lower TDP, which is seemingly unexplainable - since everything else is the same. Two of them say "LGA775, Tray" and I have no idea what "Tray" means either. Also, two of them have a different SPEC code. What I need to know is: What does "LGA775, Tray" mean? Why does the one CPU have a lower TDP? And what does that mean for me? Does that mean lower maximum power consumption? Does it mean the CPU may be more stable/endurant, because of a lower heat output? Why do two of them have a different SPEC code, and what does this mean? Finally, what does PLGA775 (as opposed to LGA775) mean, and do I need to be worried about that? Information from Intel's wbsite: Intel® Pentium® Processor Extreme Edition 955 (4M Cache, 3.46 GHz, 1066 MHz FSB) with SPEC Code 1 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 95 Watts BX80553955 SL94N 2 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL94N 3 Boxed Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775 PLGA775 B1 130 Watts BX80553955 SL8WM 4 Intel® Pentium® Processor Extreme Edition 955 4M Cache, 3.46 GHz, 1066 MHz FSB LGA775, Tray PLGA775 B1 130 Watts HH80553PH0994M SL8WM

  • jQuery and function scope

    - by Jason
    Is this: ($.fn.myFunc = function() { var Dennis = function() { /*code */ } $('#Element').click(Dennis); })(); equivalent to: ($.fn.myFunc = function() { $('#Element').click(function() { /*code */ }); })(); If not, can someone please explain the difference, and suggest the better route to take for both performance, function reuse and clarity of reading. Thanks!

  • Radeon 6950 - Garbling of text and graphics in certain Windows only

    - by Greg
    This morning I noticed the text in Gmail (in Firefox 4) looked a little funny (kind of thin, maybe some color fringing). I went to work and thought it might be some ClearType issue or something with the way Direct way that FF4 draws to the screen. When I came back from work (I left the computer on), the problem was much worse - way beyond ClearType nit-picking. The text was barely readable. I opened Chrome and there was no such problem. It seems like only Windows that use hardware acceleration are garbled, and ones that use GDI are not. But, I fired up Dragon Age and didn't notice any problems (I only really looked at the main menu though). Here is a link to a screen shot that illustrates the problem. Notice how the Windows Live Mesh window is completely unreadable, the text in Firefox 4 (left) is pretty bad, while Chrome, the Windows Control Panel, and the task bar are perfectly fine. The fact that the problem shows up in screen shots and that it only happens in certain Windows makes me confident that the problem cannot be with the monitor or DVI cable. I am using the AMD Radeon drivers from 4/27/11. The card I have (MSI Frozr II) came with a slight overclock (810Mhz) out of the box, but it looks like when I'm on the Windows desktop it's not running at full clock (CCC reports 450Mhz). Still, I underclocked it to the stock reference clock (800Mhz) and it made no difference. The idle temperature according to Afterburner is 42-44 Celsius, which seems a tad high but not enough to cause a problem - it's cold to the touch if I open up the machine. What the heck could be causing this? The problem varies in intensity. As we speak I'm in Firefox and things look better than they did earlier - it'll probably get worse again soon. Radeon 6950 (MSI Frozr II), Seasonic X 560, Core i5 2500K at stock clockspeeds, 16GB RAM, Asus P8P67 M Pro

  • Do you know why introducing jquery ui autocomplete for my dropdown boxes is also changing my listbox

    - by oo
    I am trying to change my comboboxes to use autocomplete so i leverage the code listed here (which worked perfectly for my dropdowns) The issue is that i also on the same page have a listbox with the following code: <%= Html.ListBox("Cars", Model.BodyParts.Select( x => new SelectListItem { Text = x.Name, Value = x.Id, Selected = Model.CarsSelected.Any(y => y.Id == x.Id) } ))%> and it appears that the jquery ui code is changing this to a autocomplete dropdown as well (as opposed to keeping it as a multi select list box) any idea how to prevent this from happening? i literally am just using the exact code on this page <script type="text/javascript"> (function($) { $.widget("ui.combobox", { _create: function() { var self = this; var select = this.element.hide(); var input = $("<input>") .insertAfter(select) .autocomplete({ source: function(request, response) { var matcher = new RegExp(request.term, "i"); response(select.children("option").map(function() { var text = $(this).text(); if (!request.term || matcher.test(text)) return { id: $(this).val(), label: text.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + request.term.replace(/([\^\$\(\)\[\]\{\}\*\.\+\?\|\\])/gi, "\\$1") + ")(?![^<>]*>)(?![^&;]+;)", "gi"), "<strong>$1</strong>"), value: text }; })); }, delay: 0, select: function(e, ui) { if (!ui.item) { // remove invalid value, as it didn't match anything $(this).val(""); return false; } $(this).focus(); select.val(ui.item.id); self._trigger("selected", null, { item: select.find("[value='" + ui.item.id + "']") }); }, minLength: 0 }) .addClass("ui-widget ui-widget-content ui-corner-left"); $("<button>&nbsp;</button>") .insertAfter(input) .button({ icons: { primary: "ui-icon-triangle-1-s" }, text: false }).removeClass("ui-corner-all") .addClass("ui-corner-right ui-button-icon") .position({ my: "left center", at: "right center", of: input, offset: "-1 0" }).css("top", "") .click(function() { // close if already visible if (input.autocomplete("widget").is(":visible")) { input.autocomplete("close"); return; } // pass empty string as value to search for, displaying all results input.autocomplete("search", ""); input.focus(); }); } }); })(jQuery); $(function() { $("select").combobox(); }); </script>
