  • What does it call in GWT to make 2 UI consistent?

    - by DucDigital
    I saw a video of Google I/O and found an example of GWT UI being very consistent between clients. Which you can save, add, drag and drop in almost real time between clients. I currently don't understand the basic of this (In GWT, i think it implement Comet), so is there anyone can give me a term or definition for this? so I can get it on Google for more information? Thank you very much

  • File Folder copy

    - by Dario Dias
    Below is the VBScript code. If the file/s or folder exist I get scripting error, "File already exists". How to fix that? How to create folder only if it does not exist and copy files only that are new or do not exist in source path? How to insert the username (Point 1) after "Welcome" and at (Poin 3) instead of user cancelled? Can the buttons be changed to Copy,Update,Cancel instead of Yes,No,Cancel? (Point 2) The code: Set objFSO = CreateObject("Scripting.FileSystemObject") Set wshShell = WScript.CreateObject( "WScript.Shell" ) strUserName = wshShell.ExpandEnvironmentStrings( "%USERNAME%" ) Message = " Welcome to the AVG Update Module" & vbCR '1* Message = Message & " *****************************" & vbCR & vbCR Message = Message & " Click Yes to Copy Definition Files" & vbCR & vbCR Message = Message & " OR " & vbCR & vbCR Message = Message & " Click No to Update Definition Files." & vbCR & vbCR Message = Message & " Click Cancel (ESC) to Exit." & vbCR & vbCR X = MsgBox(Message, vbYesNoCancel, "AVG Update Module") '2* 'Yes Selected Script If X = 6 then objFSO.FolderExists("E:\Updates") if TRUE then objFSO.CreateFolder ("E:\Updates") objFSO.CopyFile "c:\Docume~1\alluse~1\applic~1\avg8\update\download\*.*", "E:\Updates\" , OverwriteFiles MsgBox "Files Copied Succesfully.", vbInformation, "Copy Success" End If 'No Selected Script If X = 7 then objFSO.FolderExists("Updates") if TRUE then objFSO.CreateFolder("Updates") objFSO.CopyFile "E:\Updates\*.*", "Updates", OverwriteFiles Message = "Files Updated Successfully." & vbCR & vbCR Message = Message & "Click OK to Launch AVG GUI." & vbCR & vbCR Message = Message & "Click Cancel (ESC) to Exit." & vbCR & vbCR Y = MsgBox(Message, vbOKCancel, "Update Success") If Y = 1 then Set WshShell = CreateObject("WScript.Shell") WshShell.Run chr(34) & "C:\Progra~1\avg\avg8\avgui.exe" & Chr(34), 0 Set WshShell = Nothing End if If Y = 3 then WScript.Quit End IF 'Cancel Selection Script If X = 2 then MsgBox "No Files have been Copied/Updated.", vbExclamation, "User Cancelled" '3* End if

  • JavaCC: Please help me understand token ambiguity.

    - by java.is.for.desktop
    Hello, everyone! I had already many problems with understanding, how ambiguous tokens can be handled elegantly (or somehow at all) in JavaCC. Let's take this example: I want to parse XML processing instruction. The format is: "<?" <target> <data> "?>": target is an XML name, data can be anything except ?>, because it's the closing tag. So, lets define this in JavaCC: (I use lexical states, in this case DEFAULT and PROC_INST) TOKEN : <#NAME : (very-long-definition-from-xml-1.1-goes-here) > TOKEN : <WSS : (" " | "\t")+ > // WSS = whitespaces <DEFAULT> TOKEN : {<PI_START : "<?" > : PROC_INST} <PROC_INST> TOKEN : {<PI_TARGET : <NAME> >} <PROC_INST> TOKEN : {<PI_DATA : ~[] >} // accept everything <PROC_INST> TOKEN : {<PI_END : "?>" > : DEFAULT} Now the part which recognizes processing instructions: void PROC_INSTR() : {} { ( <PI_START> (t=<PI_TARGET>){System.out.println("target: " + t.image);} <WSS> (t=<PI_DATA>){System.out.println("data: " + t.image);} <PI_END> ) {} } The problem is (i guess): hence <PI_DATA> recognizes "everything", my definition is wrong. Let's test it with <?mytarget here-goes-some-data?>: The target is recognized: "target: mytarget". But now I get my favorite JavaCC parsing error: !! procinstparser.ParseException: Encountered "" at line 1, column 15. !! Was expecting one of: !! Encountered nothing? Was expecting nothing? Or what? Thank you, JavaCC! I know, that I could use the MORE keyword of JavaCC, but this would give me the whole processing instruction as one token, so I'd had to parse/tokenize it further by myself. Why should I do that? Am I writing a parser that does not parse? What I would need is telling JavaCC to recognize "everything until ?>" as processing instruction data. How can it be done? Thank you.

  • Where can I find WebSphere configuration files?

    - by Nicholas Key
    Hello Stackoverflow'ers, I would like to know where are the WebSphere configuration details saved? Specifically, configuration details that are shown in the Administrative Console (from the web) or from the console using wsadmin. Some of the examples would be: Java and Process Management: Class loader, Process definition, Process execution Container Settings: Session management, SIP Container Settings, Web Container Settings, Portlet Container Settings Are there XML files that persist these configuration details?

  • What does it mean to "preconcat" a matrix?

    - by Brad Hein
    In reviewing: http://developer.android.com/reference/android/graphics/Canvas.html I'm wondering translate(): "preconcat the current matrix with the specified translation" -- what does this mean? I can't find a good definition of "preconcat" anywhere on the internet! The only place I can find it is in the Android Source - I'm starting to wonder if they made it up? :) I'm familiar with "concat" or concatenate, which is to append to, so what is a pre-concat?

    I can't figure out how to forward declare a windows struct. The definition is typedef struct _CONTEXT { .... } CONTEXT, *PCONTEXT I really don't want to pull into this header, as it gets included everywhere. I've tried struct CONTEXT and struct _CONTEXT with no luck (redefinition of basic types with the actuall struct in winnt.h.

  • Objective C: Initalizing static variable with static method call

    - by adranale
    The Compiler claims an error saying: "initializer element is not constant", when I try to initialize a static variable inside a method with a call to a static method (with + in its definition). Anyway I can tell him that this method always returns the same value. I know this is not the same as static method, but there seems to be no constant methods in Objective-C (other than macros which won't work here because I am calling UI_USER_INTERFACE_IDIOM() from inside the method).

  • Building DLL via Maven with mojo-native

    - by graham.reeds
    I can build a simple dll consisting of a source file, a header file and a definition but now I am progressing beyond a simple toy dll and working towards something more complex. The DLL I am trying to compile has 2 source files, 2 headers and the dreaded stdafx pair. To compile normally you would use /Yc to compile the pch and /Yu to use it. How do you specify that with in the constraints of mojo-native's compiler options?

  • XML Schema (XSD) to Rails ActiveRecord Mapping?

    - by Incomethax
    I'm looking for a way to convert an XML Schema definition file into an ActiveRecord modeled database. Does anyone know of a tool that happens to do this? So far the best way I've found is to first load the XSD into an RDBMS like postgres or mysql and then have rails connect to do a rake db:schema:dump. This however, only leaves me with a database without rails Models. What would be the best way to import/load this xsd based database into rails?

  • Visual Studio - Attach Source Code to Reference

    - by Joe
    My C# project references a third-party DLL for which I have the source code. Can I somehow tell Visual Studio the location of that source code, so that, for example, when I press F12 to open the definition of a method in the DLL, it will open up the source code, instead of opening up the "Class [from metadata]" stub code?

  • How to create a \newenvironment in latex for a scaled table

    - by markus
    Hi, I try to define a table as a new environment. \newenvironment{scaledtable}[1]{% \begin{table}[h] \caption{xxx} \label{tab:xxx} \begin{center} \begin{tabular}{rcrrrrrrrrrrrrcc} }{ \hline \end{tabular} \end{center} \end{table}} The problem I have is that I can't use scalebox{}. If I put the closing bracket into the end definition of the environment, latex can't assign the brackets anymore. I also can not use PStricks because of pdflatex. /Markus

  • Scared of Calculus - Required to pass Differential Calculus as part of my Computer science major

    - by ke3pup
    Hi guys I'm finishing my Computer science degree in university but my fear of maths (lack of background knowledge) made me to leave all my maths units til' the very end which is now. i either take them on and pass or have to give up. I've passed all my programming units easily but knowing my poor maths skills won't do i've been staying clear of the maths units. I have to pass Differential Calculus and Linear Algebra first. With a help of book named "Linear Algebra: A Modern Introduction" i'm finding myself on track and i think i can pass the Linear Algebra unit. But with differential calculus i can't find a book to help me. They're either too advanced or just too simple for what i have to learn. The things i'm required to know for this units are: Set notation, the real number line, Complex numbers in cartesian form. Complex plane, modulus. Complex numbers in polar form. De Moivre’s Theorem. Complex powers and nth roots. Definition of ei? and ez for z complex. Applications to trigonometry. Revision of domain and range of a function Working in R3. Curves and surfaces. Functions of 2 variables. Level curves.Partial derivatives and tangent planes. The derivative as a difference quotient. Geometric significance of the derivative. Discussion of limit. Higher order partial derivatives. Limits of f(x,y). Continuity. Maxima and minima of f(x,y). The chain rule. Implicit differentiation. Directional derivatives and the gradient. Limit laws, l’Hoˆpital’s rule, composition law. Definition of sinh and cosh and their inverses. Taylor polynomials. The remainder term. Taylor series. Is there a book to help me get on track with the above? Being a student i can't buy too many books hence why i'm looking for a book that covers topics I need to know. The University library has a fairly limited collection which i took as loan but didn't find useful as it was too complex.

  • In Haskell, what does it mean if a binding "shadows an existing binding"?

  • Amazing families of algorithms over implicit graphs

    - by Diego de Estrada
    Dynamic programming is, almost by definition, to find a shortest/longest path on an implicit dag. Every DP algorithm just does this. An Holographic algorithm can be loosely described as something that counts perfect matchings in implicit planar graphs. So, my question is: are there any other families of algorithms that use well-known algorithms over implicit graphs to achieve a considerable speedup?

  • Is it possible to view the "source" for a ksh function?

    - by stevec
    Our ksh environment defines several functions, which can be listed using then "functions" ksh function. Is it possible to see the definition (ie source code) for these functions? This seems like an obvious question, but I've tried all manner of parameters to the "functions" and "function" functions with no luck. Thanks, Steve
