  • How to force a window into view

    - by Mick
    I work with four monitors and software that displays a great many windows. Every now and then things go wrong and I'll end up with a window that is partially or completely "off the screen". Is there a trick or utility that will help me rescue the windows and bring them back in to view.

  • How to update a property using Type.GetProperties() method?

    - by Richard77
    Hello, I've a collection of a class' properties and would like to update each one's value by iterating over the collection through the index. 1) I create the collection of properties this way private PropertyInfo[] GetPropertiesOfMyClass() { Type myType = (typeof(myClass)); PropertyInfo[] PropertyInfoArray = myType.GetProperties( BindingFlags.Public | BindingFlags.Instance); return PropertyInfoArray; } 2)Now, I'd like to set up the value of each one depending on the index this way public void UpdateProperty(MyClass instanceOfMyClass, string valueToUpdate, int index) { //TODO: //1. Get an individual property from the GetPropertyOfMyClass() using index //2. Update the value of an individual property of the instanceOfMyClass } I'd like to be able to call UpdateProperty from a Controller like this: UpdateProperty(instanceOfMyClass, valueToUpdate, indexOfTheProperty); Honestly, I do not know how to involve the instanceOfMyClass in the game as GetProperty only plays with myClass. Since I saw that I can use Name, PropertyType, ... to get information on the property. So, I've tried also GetPropertyOfMyClass()[index].SetValue(...), but I was lost in the arguments of its constructor, so I abandoned. What I want is to be able to update the value of a property in my collection just by using the index. Thanks for helping

  • How do you debug c/c++ source code in linux using emacs?

    - by vmihai
    Hello all, I am using emacs and autotools, to write and compile c/c++ sources on linux. I am using gdb via GUD in emacs. I have defined for convenience: F7:compile, F10:gud-next, F11:gud-step, F5:gud-cont, F9:gud-tbreak, F8:gud-until, F4:gud-print. I am mainly interested in debugging c/c++ source code on linux from emacs and I would like to get the most gdb can give. Unfortunately I am using only F4 which prints the variable under cursor. So my question is how do you guys debug the source code ? What programs do you use ? What key bindings (functionality) do you use mostly ? What do you need the debugger to do for you ? If you do weird stuff it doesn't matter. I would like to know everything to boost my speed a bit here. Thanks in advance. Mihai

  • What are the typical reasons Javascript developed on Firefox fails on IE?

    - by karlthorwald
    I developed some javascript enhanced pages that run fine on recent Firefox and Safari. I missed to check in Internet Explorer, and now I find the pages don't work on IE 6 and 7 (so far). The scripts are somehow not executed, the pages show as if javascript wasn't there, although some javascript is executed. I am using own libraries with dom manipulation, from YUI 2 I use YUI-Loader and the XML-Http-Request, and on one page I use "psupload", which depends on JQuery. I am installing Microsoft Script Editor from Office XP and will now debug. I will also write specific tests now. What are the typical failing points of IE? What direction I can keep my eyes open. I found this page, which shows some differences: http://www.quirksmode.org/compatibility.html Can you from your experience name some typical things I should look for first? I will also ask more questions here for specific tasks later, but for now I am interested in your experience why IE usually fails on scripts that run fine in Firefox

  • Writing a Compiler for .net - IL or Bytecode?

    - by Michael Stum
    I'm currently diving into the inner workings of .net, which means IL. As an exercise, I want to build a brainf..k compiler for .net (yes, they already exist, but as said it's for learning purposes). For the moment I'm just writing some text files that contain .il and compile them with ilasm, which works. But I wonder if I could/should go one level deeper and write bytecode directly? My "concern" is the Windows PE Stuff when compiling an EXE - instead of ilasm I would need some sort of Bytecode linker that would take my MSIL/CIL bytecode and generate the PE Stuff for it? Or do compilers "only" compile their language to IL and execute ilasm? Is there a managed version of it that I can call/embed from my compiler?

  • Is it possible to map a root domain URL to a Grails' controller?

    - by firnnauriel
    Let's have an example: A grails project, myproj, is deployed in Tomcat 6. It can be accessed anywhere thru this link: http://www.mycompany.com/myproj. Let's say we purchase another domain, http://newcompany.com, and we would like to point it to http://www.mycompany.com/myproj/url. If I go to http://newcompany.com/12345, it should be the same as doing http://www.mycompany.com/myproj/url/12345. Can anyone tell me if this is possible? How to implement it (change Tomcat 6 config, add code in UrlMappings.groovy)? Thanks in advance.

  • Drawing and Animating with UIView or CALayer?

    - by Markus
    hello, i am trying to implement a graph which a uiview draws. There are 3 UIViews to animate a left/right slide. The problem is, that i can't cancel the UIView animation. So I replaced the UIViews by CALayer. Now, the question is if CALayer is appicable for this? Is it normal to draw on a CALayer like this? And why is a CALayer so slow when I manipulate the frame properties. CGRect frame = curve.frame; frame.origin.x -= diffX; [curve setFrame:frame]; Is there a alternativ? P.S. I am a german guy. Sorry for mistakes.

  • What do these C# auto-generated table adapter commands do? e.g. UPDATE/INSERT followed by a SELECT

    - by RickL
    I'm working with a legacy application which I'm trying to change so that it can work with SQL CE, whilst it was originally written against SQL Server. The problem I am getting now is that when I try to do dataAdapter.Update, SQL CE complains that it is not expecting the SELECT keyword in the command text. I believe this is because SQL CE does not support batch SELECT statements. The auto-generated table adapter command looks like this... this._adapter.InsertCommand.CommandText = @"INSERT INTO [Table] ([Field1], [Field2]) VALUES (@Value1, @Value2); SELECT Field1, Field2 FROM Table WHERE (Field1 = @Value1)"; What is it doing? It looks like it is inserting new records from the datatable into the database, and then reading that record back from the database into the datatable? What's the point of that? Can I just go through the code and remove all these SELECT statements? Or is there an easier way to solve my problem of wanting to use these data adapters with SQL CE? I cannot regenerate these table adapters, as the people who knew how to have long since left.

  • Creating a simple templated control. Having issues...

    - by Jimock
    Hi, I'm trying to create a really simple templated control. I've never done it before, but I know a lot of my controls I have created in the past would have greatly benefited if I included templating ability - so I'm learning now. The problem I have is that my template is outputted on the page but my property value is not. So all I get is the static text which I include in my template. I must be doing something correctly because the control doesn't cause any errors, so it knows my public property exists. (e.g. if I try to use Container.ThisDoesntExist it throws an exception). I'd appreciate some help on this. I may be just being a complete muppet and missing something. Online tutorials on simple templated server controls seem few and far between, so if you know of one I'd like to know about it. A cut down version of my code is below. Many Thanks, James Here is my code for the control: [ParseChildren(true)] public class TemplatedControl : Control, INamingContainer { private TemplatedControlContainer theContainer; [TemplateContainer(typeof(TemplatedControlContainer)), PersistenceMode(PersistenceMode.InnerProperty)] public ITemplate ItemTemplate { get; set; } protected override void CreateChildControls() { Controls.Clear(); theContainer = new TemplatedControlContainer("Hello World"); this.ItemTemplate.InstantiateIn(theContainer); Controls.Add(theContainer); } } Here is my code for the container: [ToolboxItem(false)] public class TemplatedControlContainer : Control, INamingContainer { private string myString; public string MyString { get { return myString; } } internal TemplatedControlContainer(string mystr) { this.myString = mystr; } } Here is my mark up: <my:TemplatedControl runat="server"> <ItemTemplate> <div style="background-color: Black; color: White;"> Text Here: <%# Container.MyString %> </div> </ItemTemplate> </my:TemplatedControl>

  • 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.

  • Passing Reference types by value in C#

    - by Ajit
    I want to pass a reference type by value to a method in C#. Is there a way to do it. In C++, I could always rely on the copy constructor to come into play if I wanted to pass by Value. Is there any way in C# except: 1. Explicitly creating a new object 2. Implementing IClonable and then calling Clone method. Here's a small example: Let's take a class A in C++ which implements a copy constructor. A method func1(Class a), I can call it by saying func1(objA) (Automatically creates a copy) Does anything similar exist in C#. By the way, I'm using Visual Studio 2005.

  • Problem binding action parameters using FCKeditor, AJAX and ASP.NET MVC

    - by TonE
    I have a simple ASP.Net MVC View which contains an FCKeditor text box (created using FCKeditor's Javascript ReplaceTextArea() function). These are included within an Ajax.BeginForm helper: <% using (Ajax.BeginForm("AddText", "Letters", new AjaxOptions() { UpdateTargetId = "addTextResult" })) {%> <div> <input type="submit" value="Save" /> </div> <div> <%=Html.TextArea("testBox", "Content", new { @name = "testBox" })%> <script type=""text/javascript""> window.onload = function() { var oFCKeditor = new FCKeditor('testBox') ; var sBasePath = '<%= Url.Content("~/Content/FCKeditor/") %>'; oFCKeditor.BasePath = sBasePath; oFCKeditor.ToolbarSet = "Basic"; oFCKeditor.Height = 400; oFCKeditor.ReplaceTextarea() ; } </script> <div id="addTextResult"> </div> <%} %> The controller action hanlding this is: [ValidateInput(false)] public ActionResult AddText(string testBox) { return Content(testBox); } Upon initial submission of the Ajax Form the testBox string in the AddText action is always "Content", whatever the contents of the FCKeditor have been changed to. If the Ajax form is submitted again a second time (without further changes) the testBox paramater correctly contains the actual contents of the FCKeditor. If I use a Html.TextArea without replacing with FCKeditor it works correctly, and if I use a standard Post form submit inplace of AJAX all works as expected. Am I doing something wrong? If not is there a suitable/straight-forward workaround for this problem?

  • SATA vs SATA-II

    - by Rayne
    Hi all, I'm looking to replace my hard disk, which is a Seagate Barracuda 7200.11 ST3500320AS 500GB. My friend told me to get a SATA HDD, not a SATA-II. What is the difference between the two? And is my old HDD a SATA or SATA-II? The new HDD I'm looking at is a Seagate 7200.12 ST3500418AS, which the store assistant told me is a SATA-II. However, the Seagate website labels both as SATA only. I'm afraid that I'll buy a HDD which is incompatible with my system, especially since I'm going to install Windows 7 on it and I previously had the problem of Windows (Vista) setup not recognizing my hard drive. Would the new HDD be compatible? Thank you. Regards, Rayne

  • Does Android 2.1's Browser Support HTML 5 and What Video Format Does It Play?

    - by John Giotta
    The company I work for produces allot of video and we want to target as many devices as possible, but the question came up of what does the Android do? I personally own an Android based phone running 2.1, but I can't seem to get the HTML 5 tag to work. Even when I can trigger the browser to playback the video it just throws a notification error that it can't. Are there guidelines to producing Android/HTML 5 compatible videos? Is it truly supported?

  • Magento Flash + XML frontend

    - by Nick Dima
    Hi guys, I'm working on a Flash frontend for a Magento powered store. This frontend will be an alternative to the HTML shop so it will sit in a subdirectory and use the same Magento installation as the main HTML site. The Flash application will get the data from dynamic XML files. It needs to get almost everything as the HTML site (categories, products, cart, etc). I want this to be a Magento module that can be installed on an already existing Magento installation. I would like to use the Block classes available in Magneto's core code as they already provide a lot of the functionality needed. What steps would you take in order to achieve this? Do you know any examples or articles related to this? Thanks!
