  • Using Custom HttpHandler to redirect users in Sharepoint

    - by BeraCim
    Hi all: I need to redirect a user to a different page if they visit a certain set of pages in a web. There is one condition: I'm not allowed to touch the IIS. I have googled around and found a thing called the custom HttpHandler for WSS 3.0. It sounded like something that I can use to capture the URL the user enters (the most malicious way to get to a page that should really be redirected) and redirect them to another page/web. But having not have the chance to use it yet, I was wondering am I on the right track by using a Custom HttpHandler to redirect a user to a different page in Sharepoint using C#? Many thanks.

  • How to sound audible bell from crontab

    - by user1526251
    The command line: /bin/echo -e "\007" in bash will ring the bell. With the line: /bin/echo -e "\007" in my crontab I expected the bell to ring every minute, but it's silent. I know crontab is working because the line: /bin/touch $HOME/jkjkjk updates the file jkjkjk every minute as it should. I found a posting some years ago suggesting that standard output should be directed to /dev/tty1 in crontab. But the line: /bin/echo "\007" /dev/tty1 Still fails. What to try next?

  • Creating and using a static lib in xcode (MacOSX)

    - by Alasdair Morrison
    I am trying to create a static library in xcode and link to that static library from another program. So as a test i have created a BSD static C library project and just added the following code: //Test.h int testFunction(); //Test.cpp #include "Test.h" int testFunction() { return 12; } This compiles fine and create a .a file (libTest.a). Now i want to use it in another program so I create a new xcode project (cocoa application) Have the following code: //main.cpp #include <iostream> #include "Testlib.h" int main (int argc, char * const argv[]) { // insert code here... std::cout << "Result:\n" <<testFunction(); return 0; } //Testlib.h extern int testFunction(); I right clicked on the project - add - existing framework - add other Selected the .a file and it added it into the project view.

  • Data Binding to an object in C#

    - by Allen
    Objective-c/cocoa offers a form of binding where a control's properties (ie text in a textbox) can be bound to the property of an object. I am trying to duplicate this functionality in C# w/ .Net 3.5. I have created the following very simple class in the file MyClass.cs: class MyClass { private string myName; public string MyName { get { return myName; } set { myName = value; } } public MyClass() { myName = "Allen"; } } I also created a simple form with 1 textbox and 1 button. I init'd one instance of Myclass inside the form code and built the project. Using the DataSource Wizard in Vs2008, i selected to create a data source based on object, and selected the MyClass assembly. This created a datasource entity. I changed the databinding of the textbox to this datasource; however, the expected result (that the textbox's contents would be "allen") was not achieved. Further, putting text into the textbox is not updating the name property of the object. I know i'm missing something fundamental here. At some point i should have to tie my instance of the MyClass class that i initialized inside the form code to the textbox, but that hasn't occurred. Everything i've looked at online seems to gloss over using DataBinding with an object (or i'm missing the mark entirely), so any help is great appreciated. ----Edit--- Utilizing what i learned by the answers, i looked at the code generated by Visual Studio, it had the following: this.myClassBindingSource.DataSource = typeof(BindingTest.MyClass); if i comment that out and substitute : this.myClassBindingSource.DataSource = new MyClass(); i get the expected behavior. Why is the default code generated by VS like it is? Assuming this is more correct than the method that works, how should i modify my code to work within the bounds of what VS generated?

  • Debugging dynamically added Javascript code

    - by gilm
    One of the programmers I worked with has something similar in code: var head = document.getElementsByTagName("head")[0]; var e = document.createElement("script"); e.type = "text/javascript"; var b = "function moo() { alert('hello'); }"; e.appendChild(document.createTextNode(b)); head.appendChild(e); moo(); This is all good and dandy, but I would like to step into moo(), and firebug just can't do that. I know I can rip the whole thing apart, but I reallllly don't want to touch it and his code works :) Any ideas how I can debug this with Firebug? Cheers

  • Workaround iPhone's browser not honoring the <label> element

    - by Sorin Comanescu
    Hi, Just ran into this recently and I thought it'd be helpful to share. The HTML <label> element is supported in a weird way by iPhone's (v3) browser. Try this: <input type="checkbox" id="chkTest" /><label for="chkTest">Click me!</label> Tapping the "Click me!" label has no effect, the checkbox is not checked. Lack of support in a touch device for <label> elements puzzled me and I tried to overcome this issue by using javascript. The surprise came when a I noticed a void javascript like the one below also did the trick: <input type="checkbox" id="chkTest" /><label for="chkTest" onclick="javascript:void(0);">Click me!</label> HTH Further info: Also works with an empty handler: onclick="" Disabling JavaScript inactivates again the label, even if using the empty handler.

  • Mac OS X linker error in Qt; CoreGraphics & CGWindowListCreate

    - by Jake Petroules
    Here is my .mm file #include "windowmanagerutils.h" #ifdef Q_OS_MAC #import </System/Library/Frameworks/ApplicationServices.framework/Frameworks/CoreGraphics.framework/Headers/CGWindow.h> QRect WindowManagerUtils::getWindowRect(WId windowId) { CFArrayRef windows = CGWindowListCreate(kCGWindowListOptionOnScreenOnly, kCGNullWindowID); return QRect(); } QRect WindowManagerUtils::getClientRect(WId windowId) { return QRect(); } QString WindowManagerUtils::getWindowText(WId windowId) { return QString(); } WId WindowManagerUtils::rootWindow() { QApplication::desktop()->winId(); } WId WindowManagerUtils::windowFromPoint(const QPoint &p, WId parent, bool(*filterFunction)(WId)) { return NULL; } void WindowManagerUtils::setTopMostCarbon(const QWidget *const window, bool topMost) { if (!window) { return; } // Find a Cocoa equivalent for this Carbon function // [DllImport("/System/Library/Frameworks/Carbon.framework/Versions/Current/Carbon")] // OSStatus ret = HIViewSetZOrder(this->winId(), kHIViewZOrderAbove, NULL); } #endif The linker is telling me "_CGWindowListCreate" is undefined. What libraries must I link to? Apple's documentation is not very helpful on telling what to include or link to, like MSDN is. Also I couldn't just do #import <CGWindow.h>, I had to specify the absolute path to it... any way around that?

  • How to handle data output in an Observer?

    - by Mannaz
    I have an Observable and an Observer. The observable does download some stuff in a background thread and calls notifyObservers to let the observers read the status. At some point in public void update the observer tries to updates the GUI ((TextView)findViewById('R.id.foo')).setText("bar"); but it seems like the observable thread calls this method, because the Observable (!!!) throws this: android.view.ViewRoot$CalledFromWrongThreadException: Only the original thread that created a view hierarchy can touch its views. at android.view.ViewRoot.checkThread(ViewRoot.java:2462) at android.view.ViewRoot.requestLayout(ViewRoot.java:512) ... at com.mynamespace.acitivty.TrackActivity.startPlay(TrackActivity.java:72) at com.mynamespace.acitivty.TrackActivity.update(TrackActivity.java:107) at java.util.Observable.notifyObservers(Observable.java:147) at java.util.Observable.notifyObservers(Observable.java:128) at com.mynamespace.module.communication.Download.stateChanged(Download.java:213) at com.mynamespace.module.communication.Download.run(Download.java:186) at java.lang.Thread.run(Thread.java:1058) Is there some way I can prevent this from happening? I'm sure I'm missing something obvious here.

  • Setting Priorities on Buttons

    Hello Android Developers, I am trying to figure out how to set priorities on imagebutton. I want to have a layout with a bunch of Icon or buttons that can be selected either by touch, radio, or checked box. As these images are selected they are set on queue to be displayed in order of Precedence. (that is to be pre-determined). The images are displayed once the main action button is touched.

  • Dreamweaver - template not recognising child files until they are opened

    - by Chris
    Hi I've got a new section for a website which I have generated for a data source and it has markup for using a Dreamweaver template. When I add the new files and folders to the site , then update my template , it doesn't find the new files to update. If I open one of the new files , make a change in the template , then it recognises the new file is using the template. So it's almost like I have to touch all the files with Dreamweaver first. I've tried to open all the new files which need to use the template but then Dreamweaver CS4 crashes, I presume because of the number of files it's opening. Anyway, does anyone know if there is a way to make Dreamweaver recognise that a block of new files belong to the template , it doesn't seem to just work automatically Thanks Chris

  • (iPhone) Instruments can't "Attach to Process"

    - by AlexLive
    Actually, I'm using a second generation Ipod Touch. What I'm trying to do is to debug my app on XCode and look for any memory leaks on Instruments at the same time. Is it even possible? Because the "Attach to Process" submenu lists when my app is running (or debugging in this case) but all the items inside this menu are disabled. All I can do is start the app from Instruments but later I come across some bug and I want to see the variables and properties affected. I'm also new to Instruments. Please, could someone give me any advice? Help would be greatly appreciated!

  • What is the best area for freelance / small business developer work - and how to find it

    - by Olav
    Most freelance developers are essentially contractors - working full time and often hired through another company. What are the best options for real freelancing or small business built around development skills? (I am only looking for local clients, odesk etc is not interesting) Most options open for small companies are web sites. But most clients don't want to pay much, and there are lots of people that are willing to do it for very little money. Think if you want to do money that way you must be a "web site" business. Think the best option should be to work for companies spending a lot of resources on web and db? How could I get in touch with them? Other ideas? Part of my concept is to use some off-shoring to complement my skillset, so i should be able to do PHP or Drupal even if I am not at expert level.

  • CorePlot linker errors after upgrading iOS SDK

    - by JustinXXVII
    This seems like it's happened before but somehow ended up working itself out. It's happened again and I can't seem to get this fixed. I use the CorePlot Cocoa Touch framework. Everything was fine until I upgraded to the new 4.3 beta. Now my project won't compile, and is giving me linker errors for unknown symbols having to do with CorePlot. I've become a pro at adding the framework to my project, and I've checked and rechecked the instructions trying to do it again. Is there a button I can click or anything to just make this work again? I've used these instructions to try to re-add the framework, to no avail EDIT: By the way, this compiles just fine for simulator and runs graphs no problem. Compiling for the device gives me the linker errors, as follows: "_OBJC_CLASS_$_CPPlotRange", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPXYGraph", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPTextStyle", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPLineStyle", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPScatterPlot", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPAxisLabel", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPPlotSymbol", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPColor", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_OBJC_CLASS_$_CPFill", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o "_CPDecimalFromFloat", referenced from: -[GraphStatsWindow setNewGraph] in GraphStatsWindow.o -[iPadGraphView viewDidLoad] in iPadGraphView.o -[GraphTrendView setNewGraph] in GraphTrendView.o "_kCPPlainWhiteTheme", referenced from: -[GraphStatsWindow setNewGraph] in GraphStatsWindow.o -[iPadGraphView viewDidLoad] in iPadGraphView.o -[GraphTrendView setNewGraph] in GraphTrendView.o "_OBJC_CLASS_$_CPTheme", referenced from: objc-class-ref in GraphStatsWindow.o objc-class-ref in iPadGraphView.o objc-class-ref in GraphTrendView.o ld: symbol(s) not found for architecture armv7

  • Use trackball for scrolling in Android ListView

    - by gartenkralleb
    hi, i have a ListView, whose content should not be selectable. i set the ListView to choiceMode="none" and set a transparent listSelector. for touch mode it acts as desired. a problem is the use of the trackball. if i try to use it for scrolling, the scroll starts after the 10th push to "down". this is caused by the invisible listSelector, which scrolls down the list until the 10th list item is "invisibily" selected. i try to override dispatchTrackballEvent and do the scrolling with scrollBy, but i did not finished this approach yet, to have a look on alternative suggestions. is there a simple solution for my problem?

  • Valueurl Binding On Large Arrays Causes Sluggish User Interface

    - by Hooligancat
    I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!
