• SQL Server 2008 - Get Geography From Record

  - by user336786

  Hello, I am new to using the geography types in SQL Server 2008. I have a table in my database called "Location". "Location" has the following columns and types: Location -------- City nvarchar(256) State nvarchar(256) PostalCode nvarchar(25) Latitude decimal(9, 6) Longitude decimal(9, 6) Each Location is related to a Store record in my database. I am trying to find the stores within a 10 mile radius or postal code or city/state that a user enters. To accomplish this, I know that I need to rely on geographies. At this time I have: DECLARE @startingPoint geography; SET @startingPoint=geography::STGeomFromText('POINT(-122.34900 47.65100)', 4326); That gives me the starting point from a hard-coded textual value. However, I do not know how to convert a lat/long from my Location table into a geography instance. How do I convert a lat/long in my database to a geography instance so I can continue to work on my query? Thank you!

• Type casting Collections using Conversion Operators

  - by Vyas Bharghava

  The below code gives me User-defined conversion must convert to or from enclosing type, while snippet #2 doesn't... It seems that a user-defined conversion routine must convert to or from the class that contains the routine. What are my alternatives? Explicit operator as extension method? Anything else? public static explicit operator ObservableCollection<ViewModel>(ObservableCollection<Model> modelCollection) { var viewModelCollection = new ObservableCollection<ViewModel>(); foreach (var model in modelCollection) { viewModelCollection.Add(new ViewModel() { Model = model }); } return viewModelCollection; } Snippet #2 public static explicit operator ViewModel(Model model) { return new ViewModel() {Model = model}; } Thanks in advance!

• How to call/use a value converter inverted

  - by Soko

  Is it possible to use a converter the "wrong" way around? In other words: can I swap source and target? Here's an example: I created a simple IValueConverter called NullableDecimalToStringConverter which converts an input if "" into null and a number into decimal. I use it to bind a TextBox in my WPF view to a decimal? property in my ViewModel. In another context I'd like to convert a NullableDecimal into a String in the same way... Is it possible to simply use the existing NullableDecimalToStringConverter inverted? One method is to use the parameter of the converter to tell the converter which way it should convert. But is there a .NET build in way to do such a thing? Another way would be to build a base class with both conversion methods and two separate converter which call the base class methods...

• Is both approach same ?

  - by Harikrishna

  I have one datatable which is not bindided and records are coming from the file by parsing it in the datatable dynamically every time. Now there is three columns in the datatable Marks1,Marks2 and FinalMarks. And their types is decimal. Now for making addition of columns Marks1 and Marks2 's records and store it into FinalMarks column,For that what I do is : datatableResult.Columns["FinalMarks"].Expression="Marks1+Marks2"; It's works properly. It can be done in other way also is foreach (DataRow r in datatableResult.Rows) { r["FinalMarks"]=Convert.ToDecimal(r["Marks1"])+Convert.ToDecimal(r["Marks2"]); } Now I don't know that which is the best way to do this means performance wise. Is first approach same as second approach in background means is both approach same or what?

  So,hi there. I've created a simple EJB3 test project, the code is simple: @Stateless @Remote( { ISumaSimple.class }) public class SumaSimpleBean implements ISumaSimple { /** * Default constructor. */ public SumaSimpleBean() { // TODO Auto-generated constructor stub } @Override public int sumar(int a, int b) { // TODO Auto-generated method stub return a + b; } } public interface ISumaSimple { public int sumar(int a, int b); } Ok, my client is a stand alone spring aplication which configuration is: <bean id="sumaSimpleServicio" class="org.springframework.jndi.JndiObjectFactoryBean"> <property name="jndiEnvironment"> <props> <prop key="java.naming.factory.initial"> org.apache.openejb.client.RemoteInitialContextFactory </prop> <prop key="java.naming.provider.url"> ejbd://localhost:4201 </prop> </props> </property> <property name="jndiName" value="SumaSimpleBeanRemote" /> </bean> <bean id="clienteService" class="qtx.cliente.simple.ClienteService"> <property name="sumaSimpleServicio" ref="sumaSimpleServicio"></property> </bean> All worked smoothly, but then I tried deploying using weblogic 10.3, I just changed these values: weblogic.jndi.WLInitialContextFactory t3://localhost:7010 In weblogic jndi tree my ejb is under: SimpleEJB3SimpleEJB_jarSumaSimple3_ISumaSimple Of course I added wlclient.jar to my spring client classpath.

• PHP validating integers

  - by Mikk

  Hi, I was wondering, what would be the best way to validate an integer. I'd like this to work with strings as well, so I could to something like (string)+00003 - (int)3 (valid) (string)-027 - (int)-27 (valid) (int)33 - (int)33 (valid) (string)'33a' - (FALSE) (invalid) That is what i've go so far: function parseInt($int){ //If $int already is integer, return it if(is_int($int)){return $int;} //If not, convert it to string $int=(string)$int; //If we have '+' or '-' at the beginning of the string, remove them $validate = ($int[0] === '-' || $int[0] === '+')?substr($int, 1):$int; //If $validate matches pattern 0-9 convert $int to integer and return it //otherwise return false return preg_match('/^[0-9]+$/', $validate)?(int)$int:FALSE; } As far as I tested, this function works, but it looks like a clumsy workaround. Is there any better way to write this kind of function. I've also tried filter_var($foo, FILTER_VALIDATE_INT); but it won't accept values like '0003', '-0' etc.

• AIR SQLite IN expression not working

  - by goseta

  Hi, I'm having a problem with an expression in my sql statement in SQLite for Adobe AIR basically I have this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(19,20)"; updateStmt.parameters["@status"] = args[1]; updateStmt.execute(); if I run the above code it works, updating the status when the id are 19 and 20 but if I pass the ids list as a parameter like this sql = "UPDATE uniforms SET status=@status WHERE customerId IN(@ids)"; updateStmt.parameters["@status"] = args[1]; updateStmt.parameters["@ids"] = "19,20"; updateStmt.execute(); it gives me and error, saying could not convert text value to numeric value, which make sense because I'm passing and string but the IN expression should convert it accordingly, like it does when I pass directly the list values, why is not working the other way, thanks for any help!

• .NET Forms Abstraction for WPF, Silverlight, Winforms, WebForms, etc...

  - by tyndall

  Anyone know of a project(s) that seek to abstract form definitions on level higher than WPF, Silverlight, Winforms, WebForms, etc... I'm working on a project where we are fixing up 16 somewhat simple WebForms. But we may convert (and probably will convert to WPF or Silverlight 3 to 4 months from now. I'd rather define these forms once and be done with it. I'm willing to write a small DSL to help define forms, subforms, validation, links, and popups. I'm only looking to solve this for 80% or 90% of the forms. Four are very complicated and I'm willing to hand code these. I guess I'm looking for something like what XUL had hoped to be.

• C++ Word-Number to int

  - by Andrew

  I'm developing a program that makes basic calculations using words instead of numbers. E.g. five + two would output seven. The program becomes more complex, taking input such as two_hundred_one + five_thousand_six (201 + 5006) Through operator overloading methods, I split each number and assign it to it's own array index. two would be [0], hundred is [1], and one is [2]. Then the array recycles for 5006. My problem is, to perform the actual calculation, I need to convert the words stored in the array to actual integers. I have const string arrays such as this as a library of the words: const string units[] = { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine" }; const string teens[] = { "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" }; const string tens[] = { "", "", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" }; If my 'token' array has stored in it two hundred one in index 0, 1, and 2, I'm not sure what the best way to convert these to ints would involve.

So my question is: what tools can i use to detect the character set of those text? And how do i convert/encode/decode them properly in C#? Updates: Added some test code [TestMethod] public void TestMethod1() { string encodedText = "具有éœé›»ç”¢ç”Ÿè£ç½®ä¹‹å½±åƒè¼¸å…¥è£ç½®"; Encoding encoder = new UTF8Encoding(); byte[] postBytes = encoder.GetBytes(encodedText); postBytes = UTF8Encoding.Convert(Encoding.UTF8, Encoding.Unicode, postBytes); string decodedText = Encoding.Unicode.GetString(postBytes); Assert.AreNotEqual(encodedText, decodedText); } thanks

• int[] to string c#

  - by Robin Webdev

  Hi I'm developing an client application in C# and the server is written in c++ the server uses: inline void StrToInts(int *pInts, int Num, const char *pStr) { int Index = 0; while(Num) { char aBuf[4] = {0,0,0,0}; for(int c = 0; c < 4 && pStr[Index]; c++, Index++) aBuf[c] = pStr[Index]; *pInts = ((aBuf[0]+128)<<24)|((aBuf[1]+128)<<16)|((aBuf[2]+128)<<8)|(aBuf[3]+128); pInts++; Num--; } // null terminate pInts[-1] &= 0xffffff00; } to convert an string to int[] in my c# client i recieve: int[4] { -14240, -12938, -16988, -8832 } How do I convert the array back to an string? I don't want to use unsafe code (e.g. pointers) Any of my tries resulted in unreadable strings.

• Why does DateTime to Unix time use a double instead of an integer?

  - by Earlz

  I'm needing to convert a DateTime to a Unix timestamp. So I googled it looking for some example code In just about all the results I see, they use double as the return for such a function, even when explicitly using floor to convert it to an integer. Unix timestamps are always integers. So what problem is there with using either long or int instead of double? static double ConvertToUnixTimestamp(DateTime date) { DateTime origin = new DateTime(1970, 1, 1, 0, 0, 0, 0); TimeSpan diff = date - origin; return Math.Floor(diff.TotalSeconds); }

• Selenium navigation inside foreach loop

  - by smudgedlens

  I am having an issue with navigation. I get a list of rows from an html table. I iterate over the rows and scrape information from them. But there is also a link on the row that I click to go to more information related to the row to scrape. Then I navigate back to the page with the original table. This works for the first row, but for the subsequent rows, it throws an exception. I look at my row collection after the first time the link inside a row is clicked, and none of them have the correct values like they did before I clicked the link. I believe that there is something going on when I navigate to a different URL that I'm not getting. My code is below. How do I get this working so I can iterate over the parent table, click the links in each row, navigate to the child table, but still continue iterating over the rows in the parent table? private List<Document> getResults() { var documents = new List<Document>(); //Results IWebElement docsTable = this.webDriver.FindElements(By.TagName("table")) .Where(table => table.Text.Contains("Document List")) .FirstOrDefault(); var validDocRowRegex = new Regex(@"^(\d{3}\s+)"); var docRows = docsTable.FindElements(By.TagName("tr")) .Where(row => //It throws an exception with .FindElement() when there isn't one. row.FindElements(By.TagName("td")).FirstOrDefault() != null && //Yeah, I don't get this one either. I negate the match and so it works?? !validDocRowRegex.IsMatch( row.FindElement(By.TagName("td")).Text)) .ToList(); foreach (var docRow in docRows) { //Todo: find out why this is crashing on some documents. var cells = docRow.FindElements(By.TagName("td")); var document = new Document { DocID = Convert.ToInt32(cells.First().Text), PNum = Convert.ToInt32(cells[1].Text), AuthNum = Convert.ToInt32(cells[2].Text) }; //Go to history for the current document. cells.Where(cell => cell.FindElements(By.TagName("a")).FirstOrDefault() != null) .FirstOrDefault().Click(); //Todo: scrape child table. this.webDriver.Navigate().Back(); } return documents; }

• Creating seed model from data already in DB

  - by Nick Brown

  Is there a way to convert data in an existing database into objects that can easily be put into a seed method? Essentially I'd like to let some people add lines to my DB via a form and then convert that into an object that I can re-seed the DB anytime I need to make changes. The database itself is created via code-first using the following model: public class Combo { public int Id { get; set; } public string MainPrefix { get; set; } public string MainDescriptor { get; set; } public string MainDish { get; set; } public string Connector { get; set; } public string SecondaryDescriptor { get; set; } public string SecondaryDish { get; set; } }

• EBCDIC to ASCII conversion. Out of bound error. In C#.

  - by mekrizzy

  I tried creating a EBCDIC to ASCII convector in C# using this general conversion order(given below). Basically the program converted from ASCII to the equivalent integer and from there into EDCDIC using the order below. Now when I try compiling this in C# and try giving a EBCDIC string(got this from another file from another computer) it is showing 'Out of Bound' exception for some of the EBCDIC character. Why is this like this?? Is it about formating?? or C# ?? or windows? Extra: I tried just printing out all the ASCII and EBCDIC characters using a loop from 0..255 numbers but still its not showing many of the EBCDIC characters. Am I missing any standards? int[] eb2as = new int[256]{ 0, 1, 2, 3,156, 9,134,127,151,141,142, 11, 12, 13, 14, 15, 16, 17, 18, 19,157,133, 8,135, 24, 25,146,143, 28, 29, 30, 31, 128,129,130,131,132, 10, 23, 27,136,137,138,139,140, 5, 6, 7, 144,145, 22,147,148,149,150, 4,152,153,154,155, 20, 21,158, 26, 32,160,161,162,163,164,165,166,167,168, 91, 46, 60, 40, 43, 33, 38,169,170,171,172,173,174,175,176,177, 93, 36, 42, 41, 59, 94, 45, 47,178,179,180,181,182,183,184,185,124, 44, 37, 95, 62, 63, 186,187,188,189,190,191,192,193,194, 96, 58, 35, 64, 39, 61, 34, 195, 97, 98, 99,100,101,102,103,104,105,196,197,198,199,200,201, 202,106,107,108,109,110,111,112,113,114,203,204,205,206,207,208, 209,126,115,116,117,118,119,120,121,122,210,211,212,213,214,215, 216,217,218,219,220,221,222,223,224,225,226,227,228,229,230,231, 123, 65, 66, 67, 68, 69, 70, 71, 72, 73,232,233,234,235,236,237, 125, 74, 75, 76, 77, 78, 79, 80, 81, 82,238,239,240,241,242,243, 92,159, 83, 84, 85, 86, 87, 88, 89, 90,244,245,246,247,248,249, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57,250,251,252,253,254,255 }; The whole code is as follows: public string convertFromEBCDICtoASCII(string inputEBCDICString, int initialPos, int endPos) { string inputSubString = inputEBCDICString.Substring(initialPos, endPos); int[] e2a = new int[256]{ 0, 1, 2, 3,156, 9,134,127,151,141,142, 11, 12, 13, 14, 15, 16, 17, 18, 19,157,133, 8,135, 24, 25,146,143, 28, 29, 30, 31, 128,129,130,131,132, 10, 23, 27,136,137,138,139,140, 5, 6, 7, 144,145, 22,147,148,149,150, 4,152,153,154,155, 20, 21,158, 26, 32,160,161,162,163,164,165,166,167,168, 91, 46, 60, 40, 43, 33, 38,169,170,171,172,173,174,175,176,177, 93, 36, 42, 41, 59, 94, 45, 47,178,179,180,181,182,183,184,185,124, 44, 37, 95, 62, 63, 186,187,188,189,190,191,192,193,194, 96, 58, 35, 64, 39, 61, 34, 195, 97, 98, 99,100,101,102,103,104,105,196,197,198,199,200,201, 202,106,107,108,109,110,111,112,113,114,203,204,205,206,207,208, 209,126,115,116,117,118,119,120,121,122,210,211,212,213,214,215, 216,217,218,219,220,221,222,223,224,225,226,227,228,229,230,231, 123, 65, 66, 67, 68, 69, 70, 71, 72, 73,232,233,234,235,236,237, 125, 74, 75, 76, 77, 78, 79, 80, 81, 82,238,239,240,241,242,243, 92,159, 83, 84, 85, 86, 87, 88, 89, 90,244,245,246,247,248,249, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57,250,251,252,253,254,255 }; char chrItem = Convert.ToChar("0"); StringBuilder sb = new StringBuilder(); for (int i = 0; i < inputSubString.Length; i++) { try { chrItem = Convert.ToChar(inputSubString.Substring(i, 1)); sb.Append(Convert.ToChar(e2a[(int)chrItem])); sb.Append((int)chrItem); sb.Append((int)00); } catch (Exception ex) { Console.WriteLine("//" + ex.Message); return string.Empty; } } string result = sb.ToString(); sb = null; return result; }

Is the following transfering steps correct? put a test.jpg image on client's folder -- convert the test.jpg in client.java(main.java) class to BufferedImage -- convert the BufferedImage to mat or Iplimage in server for using openCV.I have set a hello world sample from Simple Messaging Example using Hessian , and searched from Hessian with large binary data and other websites, but still dont know how to use it! Question2. Is there a related JAVA sample code? Thank you very much. Btw, I am using ubuntu12+netbeans7.2

• Trouble converting string/character to byte in lisp

  - by WanderingPhd

  I've some data that I'm reading in using read-line and I want to convert it into a byte-array. babel:string-to-octet works for the most part except when the character\byte is larger (above 200) in which case it returns two numbers. As an example, if the character is ú using babel:string-to-octet returns (195 185) instead of 250 which is what I'm looking for. I tried a number of encodings in babel but none of them seem to work. If I use read-byte or read-sequence it does read in 250. But for reasons of backward compatibility, I'm left with using read-line and I would like to know if there is something I'm missing when using babel:string-to-octet to convert ú to 250. I'm using ccl 1.8 btw.
