• What's a good way to write batch scripts in C#?

  - by Scott Bilas

  I would like to write simple scripts in C#. Stuff I would normally use .bat or 4NT .btm files for. Copying files, parsing text, asking user input, and so on. Fairly simple but doing this stuff right in a batch file is really hard (no exceptions for example). I'm familiar with command line "scripting" wrappers like AxScript so that gets me part of the way there. What I'm missing is the easy file-manipulation framework. I want to be able to do cd(".."), copy(srcFile, destFile) type functionality. Tools I have tried: NANT, which we use in our build process. Not a good scripting tool. Insanely verbose XML syntax and to add a simple function you must write an extension assembly. Can't do it inline. PowerShell. Looks great, but I just haven't been able to switch over to this as my primary shell. Too many differences from 4NT. Whatever I do needs to run from an ordinary command prompt and not require a special shell to run it through. Can PowerShell be used as a script executor? Perl/Python/Ruby. Really hate learning an entirely new language and framework just to do batch file operations. Haven't been able to dedicate the time I need to do this. Plus, we're a 99% .NET shop for our toolchain and I really want to leverage our existing experience and codebase. Are there frameworks out there that are trying to solve this problem of "make a batch file in C#" that you have used? I want the power of C#/.NET with the immediate-mode type functionality of a typical cmd.exe shell language. Am I alone in wanting something like this?

• Google Maps + PODSCMS

  - by Sharath

  Hi, I have a column called 'location' in a POD which I have created. I was looking to write a input helper where I display a Google Map and the user clicks on a location, and I capture that into this column. This is what I am trying to do <div class="form pick <?php echo $location; ?>"> <script src="http://maps.google.com/maps?file=api&v=1&key=<key_here>" type="text/javascript"></script> <div id="map" style="width:500; height:500"> <script type="text/javascript"> map=new GMap(document.getElementById("map")); map.centerAndZoom(new GPoint(77.595062,13.043359),6); map.setUIToDefault(); </script> </div> </div> But I am getting a number of errors from google maps API. Any idea how i can get this helper in there?

• StructureMap Open Generic Types

  - by Shane Fulmer

  I have the following classes: public interface IRenderer<T> { string Render(T obj); } public class Generic<T> { } public class SampleGenericRenderer<T> : IRenderer<Generic<T>> { public string Render(Generic<T> obj) { throw new NotImplementedException(); } } I would like to be able to call StructureMap with ObjectFactory.GetInstance<IRenderer<Generic<string>>>(); and receive SampleGenericRenderer<string>. I'm currently using the following registration and receiving this error when I call GetInstance. "Unable to cast object of type 'ConsoleApplication1.SampleGenericRenderer'1[ConsoleApplication1.Generic'1[System.String]]' to type 'ConsoleApplication1.IRenderer'1[ConsoleApplication1.Generic'1[System.String]]'." public class CoreRegistry : Registry { public CoreRegistry() { Scan(assemblyScanner => { assemblyScanner.AssemblyContainingType(typeof(IRenderer<>)); assemblyScanner.AddAllTypesOf(typeof(IRenderer<>)); assemblyScanner.ConnectImplementationsToTypesClosing(typeof(IRenderer<>)); }); } } Is there any way to configure StructureMap so that it creates SampleGenericRenderer<string> instead of SampleGenericRenderer<Generic<string>>?

  Hi, I have a small problem in my code and I need your help. Well Im using fetch_assoc to get data from database and I need to get the ID number of each of returned values. the issue is that my code only return the ID number of the last data.

• Animate absolutely positioned div, but stop if a condition is true?

  - by Alex

  Hello all, I have a div which I place at the top right-hand corner of a website, absolutely positioned at top: 0px and right : 0px. I want to use jquery's animate function to animate the div left or right a certain amount when a button is clicked, but stop the animation if at anytime, the div's offset to the left or right is less than a certain number. I want to do this to accomodate users who click the left or right buttons more than once, so that the div does not fly out of sight. How does one accomplish this? Below is my relevant css, html, and jquery code: CSS: #scorecardTwo { position:absolute; padding:5px; width: 300px; background-color:#E1E1E1; right:0px; top:0px; display:none; } HTML: <div id = "scorecardTwo"> <span id = "dealHolder"><a href="some/link">some text</a></span> <br /> <span id = "scoreHolder">some text</span> <br /> <button type="button" id="moveLeft">Left</button>&nbsp;<button type="button" id="moveRight">Right</button> </div> jQuery (at the moment): $("#scorecardTwo").fadeIn("slow"); $("#moveLeft").bind("click", function() { $("#scorecardTwo").animate({"right":"+=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? }); $("#moveRight").bind("click", function() { $("#scorecardTwo").animate({"right" : "-=76%"}, "slow"); // how to stop animation if offset is less than appropriate number? });

• Trouble swapping values as keys in generic java BST class

  - by user1729869

  I was given a generic binary search tree class with the following declaration: public class BST<K extends Comparable<K>, V> I was asked to write a method that reverses the BST such that the values become the keys and keys become values. When I call the following method (defined in the class given) reverseDict.put(originalDict.get(key), key); I get the following two error messages from Netbeans: Exception in thread "main" java.lang.RuntimeException: Uncompilable source code - Erroneous sym type: BST.put And also: no suitable method found for put(V,K) method BST.put(BST<K,V>.Node,K,V) is not applicable (actual and formal argument lists differ in length) method BST.put(K,V) is not applicable (actual argument V cannot be converted to K by method invocation conversion) where V,K are type-variables: V extends Object declared in method <K,V>reverseBST(BST<K,V>) K extends Comparable<K> declared in method <K,V>reverseBST(BST<K,V>) From what the error messages are telling me, since my values do not extend Comparable I am unable to use them as keys. If I am right, how can I get around that without changing the class given (maybe a cast)?

• Are vector assignments copied by value or by reference in Google's Go language?

  - by Brian T Hannan

  In the following code, I create one peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. Then I create another peg puzzle then do a move on it which adds a move to its movesAlreadyDone vector. When I print out the values in that vector for the second one, it has the move in it from the first one along with the move from the second one. Can anyone tell me why it seems to be assigning by reference and not value? Are vector assignments copied by value or by reference in Google's Go language? package main import "fmt" import "container/vector" type Move struct { x0, y0, x1, y1 int } type PegPuzzle struct { movesAlreadyDone * vector.Vector; } func (p *PegPuzzle) InitPegPuzzle(){ p.movesAlreadyDone = vector.New(0); } func NewChildPegPuzzle(parent *PegPuzzle) *PegPuzzle{ retVal := new(PegPuzzle); retVal.movesAlreadyDone = parent.movesAlreadyDone; return retVal } func (p *PegPuzzle) doMove(move Move){ p.movesAlreadyDone.Push(move); } func (p *PegPuzzle) printPuzzleInfo(){ fmt.Printf("-----------START----------------------\n"); fmt.Printf("moves already done: %v\n", p.movesAlreadyDone); fmt.Printf("------------END-----------------------\n"); } func main() { p := new(PegPuzzle); cp1 := new(PegPuzzle); cp2 := new(PegPuzzle); p.InitPegPuzzle(); cp1 = NewChildPegPuzzle(p); cp1.doMove(Move{1,1,2,3}); cp1.printPuzzleInfo(); cp2 = NewChildPegPuzzle(p); cp2.doMove(Move{3,2,5,1}); cp2.printPuzzleInfo(); } Any help will be greatly appreciated.

• Why is my content being overwritten instead of replaced in jQuery/Ajax?

  - by Matt Nathanson

  I've got jquery being used in ajax to pass some contents into a database, my problem however has nothing to do with the db.. I have input fields in an id called #clientscontainer. When I click "save" in that container, it automatically refreshes the container correctly ... $('#clientscontainer').html(html); The problem is, a couple of those input fields (such as a description and title), have instances in another div that i want to refresh upon the save click. The other ID is: $('div#' + clientID') When I do $('div#' + clientID').html(html); it refreshes the content from clientscontainer in it instead of just the variables that I want to update. When I try to pass just the variable $(blurb).html(html); it updates the blurb but it ONLY displays that variable in the div# clientID div... whereas I just want to replace it. Here is the AJAX portion of the function ...//variables// dataToLoad = 'clientID=' + clientID + '&changeClient=yes' + '&project=' + descriptionSubTitle + '&campaign=' + descriptionTitle + '&label=' + descriptionLabel + '&descriptionedit=' + description + '&blurbedit=' + blurb; $.ajax({ type: 'post', url: ('/clients/controller.php'), datatype: 'html', data: dataToLoad, success: function(html){ dataToLoad = 'clientID=' + clientID + '&loadclient=yes&isCMS=' + editCMS; $.ajax({ type: 'post', url: '/clients/controller.php', datatype: 'html', data: dataToLoad, async: false, success: function(html){ //$('#clientscontainer').focus(function() {reInitialize()}); //$('#clientscontainer').ajaxComplete(function(){reInitialize()}); $('#clientscontainer').html(html); $('div#' + clientID).each(function(){ $('#editbutton').click(function() {EditEverything()}); } , error: function() { alert('An error occured! 222'); } });}, error: function() { alert('An error occured! 394'); } }); any suggestions?

• Run Jmol applet using apache server

  - by user1144004

  I am a newbie in using apache and jmol. I am trying to run a jmol applet in python using apache server. Because of strict folder arrangement restrictions in jmol (html and model files should be present inside jmol folder), I had to move the default htdocs and cgi-bin folder inside jmol folder by editing the "httd.conf" file. Now the new location of htdocs folder is "Apache2.2/jmol/htdocs" and of cgi-bin folder is "Apache2.2/jmol/cgi-bin". Now I've put my "start.html" file in the htdocs folder which has the jmol applet tag. It takes "CA150.XYZ" file which is also placed in the same folder. On running this "start.html" file through apache server, nothing happens. It even doesn't give any error, it just shows a blank page. But if I try to run "start.html" without apache server, jmol applet do get executed and runs successfully. What am I doing wrong? Any idea? Here is my "start.html" file <head> <title>Simple example</title> <script src="../Jmol.js" type="text/javascript"></script> </head> <body> <form> <script type="text/javascript"> jmolInitialize("../"); jmolApplet(200,"load CA150.XYZ"); </script> </form> </body>

• Performance when querying a View

  - by Nate Bross

  I'm wondering if this is a bad practice or if in general this is the correct approach. Lets say that I've created a view that combines a few attributes from a few tables. My question, what do I need to do so I can query against this view as if it were a table without worrying about performance? All attributes in the original tables are indexed, my concern is that the result view will have hundreds of thousands of records, which I will want to narrow down quite a bit based on user input. What I'd like to avoid, is having multiple versions of the code that generates this view floating around with a few extra "where" conditions to facilitate the user input filtering. For example, assume my view has this header VIEW(Name, Type, DateEntered) this may have 100,000+ rows (possibly millions). I'd like to be able to make this view in SQL Server, and then in my application write querlies like this: SELECT Name, Type, DateEntered FROM MyView WHERE DateEntered BETWEEN @date1 and @date2; Basically, I am denormalizing my data for a series of reports that need to be run, and I'd like to centralize where I pull the data from, maybe I'm not looking at this problem from the right angle though, so I'm open to alternative ways to attack this.

• VB.NET CInt(Long) behaving differently in 32- and 64-bit environments

  - by LocoDelAssembly

  Hello everybody, this is my first message here. Today I had a problem converting a Long (Int64) to an Integer (Int32). The problem is that my code was always working in 32-bit environments, but when I try THE SAME executable in a 64-bit computer it crashes with a System.OverflowException exception. I've prepared this test code in VS2008 in a new project with default settings: Module Module1 Sub Main() Dim alpha As Long = -1 Dim delta As Integer Try delta = CInt(alpha And UInteger.MaxValue) Console.WriteLine("CINT OK") delta = Convert.ToInt32(alpha And UInteger.MaxValue) Console.WriteLine("Convert.ToInt32 OK") Catch ex As Exception Console.WriteLine(ex.GetType().ToString()) Finally Console.ReadLine() End Try End Sub End Module On my 32-bit setups (Windows XP SP3 32-bit and Windows 7 32-bit) it prints "CINT OK", but in the 64-bit computer (Windows 7 64-bit) that I've tested THE SAME executable it prints the exception name only. Is this behavior documented? I tried to find a reference but failed miserably. For reference I leave the MSIL code too: .method public static void Main() cil managed { .entrypoint .custom instance void [mscorlib]System.STAThreadAttribute::.ctor() = ( 01 00 00 00 ) // Code size 88 (0x58) .maxstack 2 .locals init ([0] int64 alpha, [1] int32 delta, [2] class [mscorlib]System.Exception ex) IL_0000: nop IL_0001: ldc.i4.m1 IL_0002: conv.i8 IL_0003: stloc.0 IL_0004: nop .try { .try { IL_0005: ldloc.0 IL_0006: ldc.i4.m1 IL_0007: conv.u8 IL_0008: and IL_0009: conv.ovf.i4 IL_000a: stloc.1 IL_000b: ldstr "CINT OK" IL_0010: call void [mscorlib]System.Console::WriteLine(string) IL_0015: nop IL_0016: ldloc.0 IL_0017: ldc.i4.m1 IL_0018: conv.u8 IL_0019: and IL_001a: call int32 [mscorlib]System.Convert::ToInt32(int64) IL_001f: stloc.1 IL_0020: ldstr "Convert.ToInt32 OK" IL_0025: call void [mscorlib]System.Console::WriteLine(string) IL_002a: nop IL_002b: leave.s IL_0055 } // end .try catch [mscorlib]System.Exception { IL_002d: dup IL_002e: call void [Microsoft.VisualBasic]Microsoft.VisualBasic.CompilerServices.ProjectData::SetProjectError(class [mscorlib]System.Exception) IL_0033: stloc.2 IL_0034: nop IL_0035: ldloc.2 IL_0036: callvirt instance class [mscorlib]System.Type [mscorlib]System.Exception::GetType() IL_003b: callvirt instance string [mscorlib]System.Type::ToString() IL_0040: call void [mscorlib]System.Console::WriteLine(string) IL_0045: nop IL_0046: call void [Microsoft.VisualBasic]Microsoft.VisualBasic.CompilerServices.ProjectData::ClearProjectError() IL_004b: leave.s IL_0055 } // end handler } // end .try finally { IL_004d: nop IL_004e: call string [mscorlib]System.Console::ReadLine() IL_0053: pop IL_0054: endfinally } // end handler IL_0055: nop IL_0056: nop IL_0057: ret } // end of method Module1::Main I suspect that the instruction that is behaving differently is either conv.ovf.i4 or the ldc.i4.m1/conv.u8 pair.

• How to ignore the validation of Unknown tags ?

  - by infant programmer

  One more challenge to the XSD capability,I have been sending XML files by my clients, which will be having 0 or more undefined or [call] unexpected tags (May appear in hierarchy). Well they are redundant tags for me .. so I have got to ignore their presence, but along with them there are some set of tags which are required to be validated. This is a sample XML: <root> <undefined_1>one</undefined_1> <undefined_2>two</undefined_2> <node>to_be_validated</node> <undefined_3>two</undefined_3> <undefined_4>two</undefined_4> </root> And the XSD I tried with: <xs:element name="root" type="root"></xs:element> <xs:complexType name="root"> <xs:sequence> <xs:any maxOccurs="2" minOccurs="0"/> <xs:element name="node" type="xs:string"/> <xs:any maxOccurs="2" minOccurs="0"/> </xs:sequence> </xs:complexType XSD doesn't allow this, due to certain reasons. The above mentioned example is just a sample. The practical XML comes with the complex hierarchy of XML tags .. Kindly let me know if you can get a hack of it. By the way, The alternative solution is to insert XSL-transformation, before validation process. Well, I am avoiding it because I need to change the .Net code which triggers validation process, which is supported at the least by my company.

• How to get the Actual Link file location in VSS?

  - by Regi

  I use VSS and currently I am adding a link file using following code: int ShareFlags = (int)VSSFlags.VSSFLAG_RECURSNO; //Link in sourcesafe IVSSDatabase ssdb = GetVssDatabase(); Shared.Enums.SqlObjectSubType _sqlSubType = new Shared.Enums.SqlObjectSubType(); VSSItem SourceItem = ssdb.get_VSSItem(pSourceItemPath, false); //if source is a proj, recursively share the whole thing if (SourceItem.Type == (int)VSSItemType.VSSITEM_PROJECT) ShareFlags = (int)VSSFlags.VSSFLAG_RECURSYES; VSSItem DestItem = ssdb..get_VSSItem(pDestItemPath, false); //share the item DestItem.Share(SourceItem, pComment, ShareFlags); if (SourceItem.Type == (int)VSSItemType.VSSITEM_FILE) { bResult = true; } return bResult; This will works fine. My issue is that I need to find the actual link location. For example I have a Project named as Link and it contains 2 files say file1 and file2. I added a Link to my Working project (say CurrentProject). This current project have 2 files say f1 and f2. After sharing the Link project then we get the item in Current project as: $/CurrentProject/File1 $/CurrentProject/File2 $/CurrentProject/F1 $/CurrentProject/F2 Here File1 and File2 are link files. I need to get its parent (Actual) location i.e. $/Link/file1 and $/Link/File2 Is there any way to find Link files location using SourceSafeTypeLib?

• Passing the Class<T> in java of a generic list?

  - by Rob Stevenson-Leggett

  I have a method for reading JSON from a service, I'm using Gson to do my serialization and have written the following method using type parameters. public T getDeserializedJSON(Class<T> aClass,String url) { Reader r = getJSONDataAsReader(url); Gson gson = new Gson(); return gson.fromJson(r, aClass); } I'm consuming json which returns just an array of a type e.g. [ { "prop":"value" } { "prop":"value" } ] I have a java class which maps to this object let's call it MyClass. However to use my method I need to do this: RestClient<ArrayList<MyClass>> restClient = new RestClient<ArrayList<MyClass>>(); ArrayList<MyClass> results = restClient.getDeserializedJSON(ArrayList<MyClass>.class, url); However, I can't figure out the syntax to do it. Passing just ArrayList.class doesn't work. So is there a way I can get rid of the Class parameter or how do I get the class of the ArrayList of MyClass?

• Create and define Vector

  - by zdmytriv

  I'm looking for method to create Vector and push some values without defining variable Vector. For example: I have function: public function bla(data:Vector.<Object>):void { ... } this function expects Vector as parameter. I can pass parameters this way var newVector:Vector.<Object> = new Vector.<Object>(); newVector.push("bla1"); newVector.push("bla2"); bla(newVector); Can I do it in one line in Flex? I'm looking for something like: bla(new Vector.<Object>().push("bla1").push("bla2")); I've also tried this: bla(function():Vector.<Object> { var result:Vector.<Object> = new Vector.<Object>(2, true); result.push("bla1"); result.push("bla2"); return result; }); But it complains: 1067: Implicit coercion of a value of type Function to an unrelated type __AS3__.vec:Vector.<Object>...

• Is there a Visual Studio (or freeware) equivalent for Expression Blend's "Edit Template" feature?

  - by DanM

  In Expression Blend, you can view and edit the control template of objects in the "Objects and Timeline" panel. I'm wondering if there's an equivalent feature in Visual Studio or if there's something free (or very inexpensive) I can download that will allow me to do this. Here's a screen cap from Expression Blend that shows what I'm talking about: Doing this for DataGrid results in the following: <Style x:Key="DataGridStyle1" TargetType="{x:Type Custom:DataGrid}"> ... <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type Custom:DataGrid}"> ... </ControlTemplate> </Setter.Value> </Setter> <Style.Triggers> <Trigger Property="IsGrouping" Value="True"> <Setter Property="ScrollViewer.CanContentScroll" Value="False"/> </Trigger> </Style.Triggers> </Style> (The ... is of course replaced with setters and the contents of the control template.) This is a very useful starting point if you want to create a custom style and template for a control. It seems like you can do pretty much anything you can do in Blend in Studio, but this one is eluding me. Any ideas? Edit I'm also curious if this feature will be in Visual Studio 2010. Anyone know?

  I have noticed a rather strange behaviour in IE. I have a HTML form with a single input text field and a submit button On Submit click I need to execute a client side JavaScript function that does the necessary. Now when I want to prevent the postback in the text field (on enter key press) I have added a key press JavaScript function that looks like this: <input type=text onkeypress="return OnEnterKeyPress(event)" /> function OnEnterKeyPress(event) { var keyNum = 0; if (window.event) // IE { keyNum = event.keyCode; } else if (event.which) // Netscape/Firefox/Opera { keyNum = event.which; } else return true; if (keyNum == 13) // Enter Key pressed, then start search, else do nothing. { OnButtonClick(); return false; } else return true; } Strangly this doesn't work. But if I pass the text field to the function : <input type=text onkeypress="return OnEnterKeyPress(this,event);" /> function OnEnterKeyPress(thisForm,event) { var keyNum = 0; if (window.event) // IE { keyNum = event.keyCode; } else if (event.which) // Netscape/Firefox/Opera { keyNum = event.which; } else return true; if (keyNum == 13) // Enter Key pressed, then start search, else do nothing. { OnButtonClick(); return false; } else return true; } I am able to prevent the postback. Can anyone confirm what is exactly happening here?? the HTML form has just one text box and a submit button The resultant o/p of the JavaScript function executed on submit is displayed in a HTML text area in a separate div.

• Interpretation of int (*a)[3]

  - by kapuzineralex

  When working with arrays and pointers in C, one quickly discovers that they are by no means equivalent although it might seem so at a first glance. I know about the differences in L-values and R-values. Still, recently I tried to find out the type of a pointer that I could use in conjunction with a two-dimensional array, i.e. int foo[2][3]; int (*a)[3] = foo; However, I just can't find out how the compiler "understands" the type definition of a in spite of the regular operator precedence rules for * and []. If instead I were to use a typedef, the problem becomes significantly simpler: int foo[2][3]; typedef int my_t[3]; my_t *a = foo; At the bottom line, can someone answer me the questions as to how the term int (*a)[3] is read by the compiler? int a[3] is simple, int *a[3] is simple as well. But then, why is it not int *(a[3])? EDIT: Of course, instead of "typecast" I meant "typedef" (it was just a typo).

• Pass Arguments to Included Module in Ruby?

  - by viatropos

  I'm hoping to implement something like all of the great plugins out there for ruby, so that you can do this: acts_as_commentable has_attached_file :avatar But I have one constraint: That helper method can only include a module; it can't define any variables or methods. The reason for this is because, I want the options hash to define something like type, and that could be converted into one of say 20 different 'workhorse' modules, all of which I could sum up in a line like this: def dynamic_method(options = {}) include ("My::Helpers::#{options[:type].to_s.camelize}").constantize(options) end Then those 'workhorses' would handle the options, doing things like: has_many "#{options[:something]}" Here's what the structure looks like, and I'm wondering if you know the missing piece in the puzzle: # 1 - The workhorse, encapsuling all dynamic variables module My::Module def self.included(base) base.extend ClassMethods base.class_eval do include InstanceMethods end end module InstanceMethods self.instance_eval %Q? def #{options[:my_method]} "world!" end ? end module ClassMethods end end # 2 - all this does is define that helper method module HelperModule def self.included(base) base.extend(ClassMethods) end module ClassMethods def dynamic_method(options = {}) # don't know how to get options through! include My::Module(options) end end end # 3 - send it to active_record ActiveRecord::Base.send(:include, HelperModule) # 4 - what it looks like class TestClass < ActiveRecord::Base dynamic_method :my_method => "hello" end puts TestClass.new.hello #=> "world!" That %Q? I'm not totally sure how to use, but I'm basically just wanting to somehow be able to pass the options hash from that helper method into the workhorse module. Is that possible? That way, the workhorse module could define all sorts of functionality, but I could name the variables whatever I wanted at runtime.
