  • Is it possible to access a Silverlight control via the COM automation model?

    - by dlanod
    What I'm trying to attempt is to access methods on a Silverlight control via the COM automation model. Theoretically it should be possible, as exposing the Silverlight control's methods as scriptable members exposes them through an IDispatch interface. I have been able to access the IDispatch interface through the automation model correctly but when I attempt to call a method on the exposed interface via Invoke it crashes. I was wondering if anyone knew whether this was expected behaviour, i.e. I'm violating some basic sandboxing requirement, or whether this should work and it is just something in my implementation that needs correcting? Cheers.

  • ubuntu 10.04 logs itself out overnight

    - by Corey
    Every night when I leave work, I lock the screen via ubuntu's "power" button in the top right hand panel. When I come to work in the morning, I'm greeted with the log-in screen. This doesn't happen every night, but most. I'm running ubuntu 10.04 on a Dell inspiron. I've included some HW specs, and also dmesg output. Please let me know what other logs may be useful. thanks!

  • How do I get an unexpanded REG_EXPAND_SZ string from a remote registry?

    - by dalehhirt
    I am currently using RegistryKey.GetValue(string name, object defaultValue, RegistryValueOptions options) with RegistryValueOptions.DoNotExpandEnvironmentNames for the options value. However, this is only valid when run on the local machine. Digging down via Reflector, I find it expands the strings locally. Which means that irrespective of the setting, the strings come down remotely already expanded. Has anyone come across a solution to this that does not require running a process directly on the remote machine to get a REG_EXPAND_SZ value? Update: I attempted to use WMI's StdRegProv provider to gain access, but it still expands the strings before sending them back.

  • Blackberry Player, custom data source

    - by Alex
    Hello I must create a custom media player within the application with support for mp3 and wav files. I read in the documentation i cant seek or get the media file duration without a custom datasoruce. I checked the demo in the JDE 4.6 but i have still problems... I cant get the duration, it return much more then the expected so i`m sure i screwed up something while i modified the code to read the mp3 file locally from the filesystem. Somebody can help me what i did wrong ? (I can hear the mp3, so the player plays it correctly from start to end) I must support OSs = 4.6.

  • Can the Windows Media Player COM control play AVI files from memory (instead of from a file)?

    - by MusiGenesis
    I have a C# app, and I'm looking at using the Windows Media Player COM control to play animation and audio. So far, the only way I see of programatically controlling what the control is playing is to set its URL property to point to some file (I assume there's some way to pass in a playlist). Is there any way the WMP can render an AVI that is entirely in-memory, like a MemoryStream or something? If so, can WMP skip from one AVI to the next seamlessly (i.e. no glitch in either the audio or the video as it transitions from one to the next)? If WMP only plays files, is there some way to cue up a list of the files in advance of play start? If so, can WMP be made to skip from one file to the next without a brief interruption? Any knowledge or links to knowledge would be much appreciated.

  • Is it feasible to write a Firefox plugin to make use of ActiveX control on Windows?

    - by Gary B2312321321
    I use an ActiveX control called TAPIEx enabling TAPI phone system integration using MS Access 2000 (+Visual Basic). I want to turn this Access database into a web app with the clients running Firefox (all on internal network). Since Firefox doesnt support ActiveX is it feasible for me to write a Firefox plugin that in turn utilizes the ActiveX control? With regard to how plugins work - Would I be able to call 'functions' of the plugin from page script (eg dial call specifying phone number, check if calls in process)? Would adding these functions to the Firefox right click menu 'globally' inside Firefox be easier? Hope you guys can help. Note I'm not a fulltime programmer; I just need to know how steep the learning curve will be or even if my idea is possible! Ive now found a project to allow using activex controls in firefox that seems to be quite up to date at: http://code.google.com/p/ff-activex-host/

  • XDebug, how to disable remote debugging for single .php file?

    - by Kirzilla
    Hello, I'm using Eclipse IDE + remote Xdebug. EclipseIDE is listening 9000 port for some kind of Xdebug information. There are some php scripts running by cron on server. So, every cron execution xdebug is sending information to my workstation and EclipseIDE is trying to find this file in my project. But file couldn't be find because cron running scrits do not relate to the project I'm working with. So, every cron run Eclipse IDE is alerting this message http://img2.pict.com/22/fc/86/3299517/0/screenshot2b142.png I've tried to add to cron executed php scripts some strings... if (function_exists('xdebug_disable')) { xdebug_disable(); } ... but it didn't helped. Any ideas? Thank you

  • Erlang: How to view output of io:format/2 calls in processes spawned on remote nodes.

    - by jkndrkn
    Hello, I am working on a decentralized Erlang application. I am currently working on a single PC and creating multiple nodes by initializing erl with the -sname flag. When I spawn a process using spawn/4 on its home node, I can see output generated by calls io:format/2 within that process in its home erl instance. When I spawn a process remotely by using spawn/4 in combination with register_name, output of io:format/2 is sometimes redirected back to the erl instance where the remote spawn/4 call was made, and sometimes remains completely invisible. Similarly, when I use rpc:call/4, output of io:format/2 calls is redirected back to the erl instance where the `rpc:call/4' call is made. How do you get a process to emit debugging output back to its parent erl instance?

  • Which cross threading invoke function is better for a control that is inherited?

    - by Stevoni
    I have a relatively simple question regarding the best way to call the DataGridView.Rows.Add function when it is inherited into the current control. Which is the best way to make the call to the inherited control? Call it directly in the invoke or call it using recursive-like function? They both seem to produce the same result, a row gets added and the quantity is returned, but which is the most efficient? The delegate: Private Delegate Function ReturnDelegate() As Object The two ways are: A) Private Overloads Function AddRow() As Integer If InvokeRequired Then Return CInt(Invoke(New ReturnDelegate(AddressOf AddRow))) Else Return Rows.Add() End If End Function Or B) Private Function RowsAdd() As Integer If Me.InvokeRequired Then Return CInt(Me.Invoke(New ReturnDelegate(AddressOf MyBase.Rows.Add))) Else Return MyBase.Rows.Add End If End Function

  • How to impose control access on flash player streaming through RTMP?

    - by MobiHunterz
    Hi, I'm using ICECAST and I'm streaming AAC/HE-AACv2 audio/video file through flash player and on iPhone. Both are separate. But when I submit url in WINAMP to stream it's requesting username/password. But when I use it with flash player, it just starts streaming. My case is I want to use same streaming (RTMP) for both website and iPhone app and i want to impose control access over my flash player to authenticate who can see streamed video. So, I need to allow access to authenticated users only to see flash player or just reject playing. Now, my provider is not supporting control access on flash player, but i need to do it... can u say how i can do this? Any kind of help will be appreciated. Thanks.

  • Is it possible to control the destination folder when checking out a project from VSS 2005?

    - by swolff1978
    We are currently using VSS 2005 for source control - and please let me start by saying, I've read a lot of posts on Stackoverflow and I realize VSS is the devil. That being said... its what we have to work with now and I have a question about the checkout process. We have the code organized in a certain hierarchy on the vss server, but when we do a checkout we don't need that same hierarchy on our machines. Is there a way to control how visual studio 2008 and vss 2005 create the checkout destination folder so that I don't end up with the code being 9 folders deep on MY machine?

  • How can I pass a mouse click to a parent control?

    - by grimus
    In a Silverlight 2 app, I am using Rectangles on a Canvas to draw a representation of data. I would like to have mouse clicks on the Rectangles be passed on to the control that owns the Canvas. I would also like to be able to show a tooltip with a summary of the data when the mouse is over a Rectangle. So far I've only been able to achieve one item or the other. If I make the Rectangles have their IsHitTestVisible property = false, the tooltips don't work, but the owning control will receive the mouse clicks. If I set it to true, then tooltips do work, but the clicks don't get passed on. Is there a way to have a Silverlight item be IsHitTestvisible = true, and pass on the mouse clicks?

  • How can I add an Items-like property to my User Control?

    - by Dan Tao
    It's pretty straightforward to add simple properties to a User Control that will appear in the desired categories in the Windows Forms designer, e.g.: [Category("Appearance")] public Color BackColor { get { return _textBox.BackColor; } set { _textBox.BackColor = value; } } What if I want to expose a more complex property, such as a collection of items of a type I define? I'm thinking something along the lines of the ListView.Items property, or the DataGridView.Columns property -- where the user of the control can access this complex property via a more specialized pop-up form (as opposed to a simple TextBox or ComboBox). Even a simple nudge in the right direction would be much appreciated.

  • How to copy from C# control and paste link into excel.

    - by Steve H.
    I have an application that I want to link to excel. I have no preference which control is used as long as I can copy the data or control, and paste link into excel. When the data changes in my application, I want the cell to change in excel. I have a client that claims it is possible and he has seen it, but has no proof and may be confused. I have searched the internet and have come up with a number of half-solutions, and people who want the opposite of what I want. Does anyone know the full solution?

  • Adding a custom control to a page, then adding multiple custom children into that one, null user con

    - by Rickjaah
    Hello all, While nerding my way through the day again. I came across a problem concerning adding children to an already add child control. I can add the controls, but when trying to use the controls in the added control, they all return null. This is the method: protected override CreateChildControls(EventArgs e) { UserControl uControl = LoadControl("~/controls/TwoColumn.ascx"); PlaceHolder holder = uControl.Controls.FindControl(phrContentMiddle) as PlaceHolder; holder.Controls.Add(LoadControl("~/controls/ImageShowControl"); } When i try to call any type of button/UserControl inside the ImageShowControl.... All return null. Is this something in the Page LifeCycle? If so, what is the way to go to realize this?

  • Simple github fetch/merge not pulling in remote branch?

    - by chum of chance
    I have a project I forked on github to my repository. I made changes on the "experiment" branch of the project the committed the project to my fork. If you go to my branch on Github you can see the that the experiment branch was correctly committed. I would like to merge the experiment branch with the original repo (which I have rights to). I issued the following commands: git clone [email protected]:originalrepo/theproject.git git checkout -b experiment origin/experiment cd theproject git remote add experiment [email protected]:chumofchance/theproject.git git fetch experiment git merge experiment "Already up to date" However, when I view the project in explorer, it appears that nothing has changed. Am I screwing something up in regards to fetching the experiment branch (vs the master branch)?

  • How to control Time zone formatting in System.Xml.Serialization or during application execution?

    - by Beal
    I'm developing a C# .Net Application that is executing on a system located in the Central Time Zone. The application gets information from a third party using an API they provide. I have used the WSDL to produce the code that my application access the API with...their reporting API allows you to define a start date and end date for the report. These are C# DateTime fields and XSD:dateTime. Now when I set the start date and end dates and allow the API to create the SOAP messages the dates don't always include a Time Zone unless I set the date fields using the ToLocalTime method; however, the method will create the DateTime fields in the Central Time Zone (CST) but I need to have it create these fields in the Pacific Time Zone (PST). If I set my machine time to PST all is good...but of course that causes other time issues. What methods can I use to control the formatting of the DateTime? Alternatively, is there a application setting that can be set in C# that allows timezone control?

  • How do I pass a reference type to Control.Invoke / display a form centered on the main form

    - by Rubio
    I'm on a thread other than the UI thread and need to display a modal form that's centered on the application's main form. What I usually do is use the width and height of the main form and the modal form to calculate the location, then use the PointToScreen method of the main form to get the location of the modal form. Since I'm on another thread I need to use Control.Invoke to call this method. I just can't figure out how to pass a parameter of type Point to Control.Invoke (params object[]). Value types and String works fine. Or, if someone can find a better way to display a form centered on the main form regardless of thread, that would be great. MessageBox seems to be able to do this (although not modally).

  • Differences between WPF Custom Control Library and plain Class Library?

    - by David Veeneman
    I posted a question a few months ago about sharing resource dictionaries across assemblies. It turns out you can do that using the Component Resource Key markup extension. At the time, I could only get it working with a WPF Custom Control project, not with a plain Class Library project. Now I need to use an existing plain Class Library project to host a shared resource dictionary. That means I need to retrofit the Class Library project to support the Component Resource Key markup extension. I have added a Themes folder and a Generic.xaml resource dictionary document to the Class Library project, as well as references to PresentationCore, PresentationFramework, and WindowsBase. Unfortunately, that doesn't seem to do the trick. So, here is my question: Other than the above, what does a WPF Custom Control Library project have that a plain Class Library project doesn't? Or, to put it another way, what else could I add to my class library project to get this feature working? Thanks.

  • Referencing a control inside a XSL Template from code behind ?

    - by Mina Samy
    Hi all I have a custom NewItem.aspx that I made by creating a new aspx from the exisiting one I wanted to put a control in a row inside the XSL Template like this <asp:DropDownList ID="ddlSectors" AutoPostBack="true" runat="server" __designer:bind="{ddwrt:DataBind('i',ddlSectors,'SelectedValue','TextChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Sector')}"> </asp:DropDownList> <!--<SharePoint:FormField runat="server" id="ff7{$Pos}" ControlMode="New" FieldName="Sector" __designer:bind="{ddwrt:DataBind('i',concat('ff7',$Pos),'Value','ValueChanged','ID',ddwrt:EscapeDelims(string(@ID)),'@Sector')}"/>--> <SharePoint:FieldDescription runat="server" id="ff7description{$Pos}" FieldName="Sector" ControlMode="New"/> Now I want to reference ddlSectors from my code library but it always throws an object reference not set to an instatnce of an object. I believe that this is becuase the control is inside the XSL template. so is there any workaround for this ? thanks
