• i can't see a context menu of WPF windows app through VNC

  - by tk

  I can open a context menu but cannot see the opened menu list through VNC. (I know that i can open the context menu by checking the vnc server machine directly) I tested on different vnc servers / clients machines (although all of them are windows Vista), and different wpf app, but still I cant see any menu list. Is this a reported problem? I found some information about wpf problem relating to windows desktop, but i dont know about vnc. ADDED : I dont have this problem on windows native apps or windows forms apps under my vnc environment.

• help, stuck with logic variable comparison loop, javascript

  - by Jamex

  I have an input text box for search of input, the id of the text box is: id="search". if a user enters 'cat' at first and hit search. In the function, I get the value 'cat' by using the syntax: var input = document.getElementById("search").value; After that, the user enter 'dog' in the search box and hit search using the same function. The function would assign 'dog' to the input variable. How would I compare the current value (dog) to the previously entered value (cat)? I have tried to assign the original input with a statement, something like var orig = input; but that would only overwrite the original input with the new input. What is the logical approach to this problem.

• Copying a mysql database from localhost to remote server using mysqldump.exe

  - by Ankur

  I want to copy a mysql database from my local computer to a remote server. I am trying to use the mysql dump command. All the examples on the internet suggest doing something like The initial mysql> is just the prompt I get after logging in. mysql> mysqldump -u user -p pass myDBName | NewDBName.out; But when I do this I get You have an error in your SQL syntax; check the manual that corresponds ... to use near 'mysqldump -u user -p pass myDBName | NewDBName.out' Since I have already logged in do I need to use -u and -p? Not doing so gives me the same error. Can you see what is wrong?

• Printing All Entries in A PHP Table

  - by mgunawan

  I'm trying to insert a php excerpt with SQL (I understand this is outdated, but am trying to grasp the syntax first) into my HTML page, and I've got the following table: ID Name Element1 Element2 0 John John's 1st John's 2nd 1 Bill Bill's 1st Bill's 2nd 2 Steve Steven's 1st Steve's 2nd I'm trying to get the for loop that will essentially print out the following in my html page Name: Name where ID=0 Element1: Element1 where ID=0 Element2: Element2 where ID=0 Name: Name where ID=1 Element1: Element1 where ID=1 Element2: Element2 where ID=1 and so forth. Basically, I am trying to make this process automated so that whenever a new record is added into the table, the HTML page will automatically update with a new "profile". Thank you for your help!

• Get ANSI-colored output from external command

  - by German Rumm

  I am writing a small script for watchr that runs my PHP unit tests. Current script runs tests using system() and displays them colored. I am trying to add libnotify functionality, but for that I need to parse the output and match against regexp, so that notification will either display green or red. system() doesn't return output, %x does return, but puts p doesn't display colors, which I need to quickly see which test failed. One option would be to run tests twice - once for display in terminal window, and second time for checking which notification to show, but I would rather avoid it.

• How do I pass (by value) a struct in Objective-C?

  - by Striker

  This one has been driving me mad! I have a struct: typedef struct{ int a; }myStruct; Then I have: myStruct tempStruct; I am trying to pass the struct to a class method whose implementation is: - (void) myFunc:(struct myStruct)oneOfMyStructs{}; I call the method like so: [myClass myFunc:(struct myStruct)tempStruct]; The compiler complains about "Conversion to non-scalar type requested." All I want to do is pass a struct into a class method, but the syntax has me a bit confused. I'm new to Objective-C. Please let me know if you can see where I'm going wrong. I've not been able to pass by reference either, so if you could help me out with that, that would be great! Thanks!

• Comparing datetimes does not work

  - by Koning Baard XIV

  I'm creating a Rails application which uses MySQL. I have a table in my DB like this: create_table "pastes", :force => true do |t| t.string "title" t.text "body" t.string "syntax" t.boolean "private" t.datetime "expire" t.string "password" t.datetime "created_at" t.datetime "updated_at" end I want to show only the non-expired pastes to people, so I do this: @pastes = Paste.find(:all, :conditions => "expire < '#{Time.now.strftime('%Y-%m-%d %H:%M:%S')}'") However, even that returns ALL pastes. Not just those that are not expired yet. Can anyone help me? Thanks Oh, changing < to > returns no pastes, not even the non-expired ones :(

• Can I customize cloning in Script.aculo.us's ghosting?

  - by Peeja

  I have a Draggable in Script.aculo.us. I'd like to use ghosting, which clones the dragged element, so you appear to be dragging a "ghost" of the element. However, this element contains an iframe. When I begin the drag, the clone's iframe loads, which is annoying. I'd like a chance to remove the iframe from the clone. How can I do that? (Just to complicate matters: the original and the clone appear to have the same id, so I'm not sure how I'd even tell them apart without checking their styling, which seems overly hackish.)

• Need help with a LINQ ArgumentOutOfRangeException in C#

  - by Christopher Klein

  Hi there, Hoping this is a nice softball of a question for a friday but I have the following line of code: //System.ArgumentOutOfRangeException generated if there is no matching data currentAnswers = new CurrentAnswersCollection().Where("PARTICIPANT_ID", 10000).Load()[0]; CurrentAnswersCollection is a strongly-typed collection populated by a view going back to my database. The problem of course is that if there is not a corresponding PARTICIPANT_ID = 10000 I get the error message. Is there a better way to write this so that I wouldn't get the error message at all? I just dont know enough about LINQ syntax to know if I can test for the existance first? thanks.

• Can I stop ASP.NET from returning 'The resource cannot be found.'?

  - by mackenir

  I have installed an HttpModule into my web app that will handle all requests with a given file extension. I want ASP.NET to handle all requests with the extension, regardless of whether there is an underlying file on disk. So, when I added the extension to the 'Application Extension Mappings', I unchecked the 'Verify that file exists' checkbox. However, this just transfers the file check to ASP.NET rather IIS, so I just get a different error page when requesting URLs with the file extension. Is there a way to preempt this ASP.NET file checking and intercept the requests?

• Using PowerShell class to invoke a "[namespace.class]::method" style command

  - by Marco

  Hello, I created a powershell object via .net to invoke commands. When I invoke normal commands like 'Get-Process' I had no problems: ps.AddCommand("Get-Process").AddParameter(...).Invoke() but I'm not able to invoke a .net method with the syntax "[namespace.class]::method", just to make an example to invoke [System.IO.File]::Exists("c:\boo.txt"). I tried with ps.AddCommand("[System.IO.File]::Exists(\"c:\\boo.txt\")").Invoke() ps.AddCommand("[System.IO.File]::Exists").AddArgument("c:\\boo.txt").Invoke() and some others. It always throws an exception which says that the command specified is not recognized. There is a way to invoke that type of command? Thanks

• Can't get Angular Dart Router to work

  - by JesterXL

  I've tried this syntax in AngularDart 0.11.0: Angular Dart passing data from route service into a controller module.value(RouteInitializerFn, configureRoutes); void configureRoutes(Router router, RouteViewFactory views) { print("configureRoutes"); views.configure({ 'login': ngRoute( path: '/login', view: 'login/login.tpl.html'), 'today': ngRoute( path: '/today', view: '/today/today.tpl.html') }); However, my routing function never seems to get called. I've used both a print statement and breakpoint to no avail. When I attempt to call it like so: WorkoutLoggerApplication(this.rootScope, this.router) { print("WorkoutLoggerApplication::constructor"); new Future.delayed(new Duration(seconds: 2), () { router.go("login", {}); }); } I get: Bad state: Invalid route name: login I've tried 0.10.0, but no dice. I've also tried 3 varieties of the new bind function format, both also don't seem to ever fire the routing function.

• Knowing the fundamentals of Java what is the right approach to learn Groovy?

  - by Liuh

  As my question already implies I want to learn a new language and have read several articles about groovy and its more pragmatic syntax. SO I have choosen Groovy as the language of my choice. What is a good way to learn a new language like Groovy when I already know the fundamentals of Java. When I understand correctly Groovy will be running in the Java Virtual Machine and allows me to always rely on what I know from Java when I don't know how to solve the problem in Groovy. I am looking for hints on how to organize a learning track to learn this language. I found that page explaining the differences: http://groovy.codehaus.org/Differences+from+Java But what I am looking for is more a tutorial where I can get through and get introduced to the differences.

• Javascript appending onload to a popup window

  - by Hypnotic Meat

  I'm trying to append an onload event to a popup window in the following manner: var explorerWindow = window.open(PARAMS...); explorerWindow.onload = function() {window.opener.unlockObj(id);} The idea is to make the button that generates the popup window readonly, making it usable again once the popup window has loaded all of its contents. However, the event doesn't seem to be firing at all. I even changed it to the following and got nothing: explorerWindow.onload = function() {alert("bloop");} Is there something terribly wrong with my syntax or am I missing something else entirely? Also, I'm using JQuery if there are any appropriate gems there that will help in this situation. I tried the following with similar results, but I'm not so sure I got the call right: $(explorerWindow).load(function() {alert("bloop");}); Any help is greatly appreciated.

• TFS 2010 Source Branches Never The Same

  - by Lukasz

  I have my root branch lets call it Alpha and one branch that was branched from that root lets call it Beta. I made some changes in the Beta branch and merged them back to Alpha. In theory now Alpha and Beta should be identical branches and when I do a diff they are identical. If I attempt to merge Alpha with Beta again without making any changes the changes I originally merged from Beta to Alpha will merge again from Alpha to Beta. Completing that merge and checking in the branches are the same. Now I can merge again. I can do this over and over again with no end. I was just wondering if anyone has ran into this problem before and how it can be fix. At first I thought it was harmless but when I make more changes in the Beta branch and merge the new changes as well as the original changes get merges overriding changes to these files making a mess. Thanks!

• Remote XML retrieval

  - by rrrfusco

  I'm retrieving a remote XML file with wget -O remotefile localfile with a cron tab. Every so often the local file becomes malformed probably because of double whitespace (according to firefox) between the CDATA tags. Sometimes the parser gives an error for ' > ' missing, but upon checking the xml file the ' > ' exists... The remote xml file never gives malformed errors when called in the url. EDIT It seems CDATA is not parsed by the xml parser. (w3schools) Is there a way to set wget to retain wellformed XML? If not wget, What is a good way to continously retrieve a remote XML file and keep it well formed?

• Floating point comparison in STL, BOOST

  - by Paul

  Is there in the STL or in Boost a set of generic simple comparison functions? The one I found are always requiring template parameters, and/or instantiation of a struct template. I'm looking for something with a syntax like : if ( is_greater(x,y) ) { ... } Which could be implemented as : template <typename T> bool is_greater(const T& x, const T& y) { return x > y + Precision<T>::eps; }

• Visual C++ 2008 doesn't recognize Windows declared types

  - by David Thornley

  I have a program that doesn't seem to recognize declared types in the latest U3D software. There's a line typedef BOOL (WINAPI* GMI)(HMON, LPMONITORINFOEX); which gets the error: Error 1 error C2061: syntax error : identifier 'LPMONITORINFOEX' c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 28 and a line MONITORINFOEX miMon; which gets Error 5 error C2065: 'miMon' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 Error 3 error C2065: 'MONITORINFOEX' : undeclared identifier c:\Projects\U3D\Source\RTL\Platform\Common\Win32\IFXOSRender.cpp 49 The program's first non-comment statement is #include <windows.h>, which includes winuser.h, which defines these identifiers. In Visual Studio, I can right-click on them and go to the definition (a typedef) and from the typedef to the struct. WINAPI is defined in WinDef.h, so that seems to be working. There are no redefinitions of LPMONITORINFOEX or MONITORINFOEX in any other file. So, how can this be happening, and what can I do about it?

• How do you make Python wait so that you can read the output?

  - by anonnoir

  I've always been a heavy user of Notepad2, as it is fast, feature-rich, and supports syntax highlighting. Recently I've been using it for Python. My problem: when I finish editing a certain Python source code, and try to launch it, the screen disappears before I can see the output pop up. Is there any way for me to make the results wait so that I can read it, short of using an input() or time-delay function? Otherwise I'd have to use IDLE, because of the output that stops for you to read. (My apologies if this question is a silly one, but I'm very new at Python and programming in general.)

• Can I have code that executes before and after tests are run by NUnit?

  - by Billy ONeal

  I've got a bunch of tests in NUnit which create garbage data on the filesystem (bad, I know, but I have little control over this). Currently we have a cleanup tool that removes these temporaries and such, but I'd like to be able to run that cleanup tool automatically. I'd have to be able to run it after all tests have finished running. I have similar checking that I'd like to do at the beginning, to ensure that there are none of these temporaries left from previous runs that might change the outcome of the tests. Is such a thing simple or am I going to have to implement a whole new test runner for such a thing?

• file_operations Question, how do i know if a process that opened a file for writing has decided to c

  - by djTeller

  Hi Kernel Gurus, I'm currently writing a simple "multicaster" module. Only one process can open a proc filesystem file for writing, and the rest can open it for reading. To do so i use the inode_operation .permission callback, I check the operation and when i detect someone open a file for writing I set a flag ON. i need a way to detect if a process that opened a file for writing has decided to close the file so i can set the flag OFF, so someone else can open for writing. Currently in case someone is open for writing i save the current-pid of that process and when the .close callback is called I check if that process is the one I saved earlier. Is there a better way to do that? Without saving the pid, perhaps checking the files that the current process has opened and it's permission... Thanks!

• Same Activity called twice... Issue with Multiple AsyncTasks?

  - by stormin986

  I have three simultaneous instances of an AsyncTask for download three files. When two particular ones finish, at the end of onPostExecute() I check a flag set by each, and if both are true, I call startActivity() for the next Activity. I am currently seeing the activity called twice, or something that resembles this type of behavior. Since the screen does that 'swipe left' kind of transition to the next activity, it sometimes does it twice (and when I hit back, it goes back to the same activity). It's obvious two versions of the activity that SHOULD only get called once are being put on the Activity stack. Could this be from both onPostExecute()s executing simultaneously and both checking the flags each other set at the exact same time? This seems extremely unlikely since two processes would have to be running line-by-line in parallel... *EDIT* A lot removed from this question since I was way off in what I thought was wrong. Nonetheless I found the answer here quite useful, so I have edited the question to reflect the useful parts.
