• The "CreateRiaClientFilesTask" task failed unexpectedly.

  - by Mohammadreza

  Hi guys. I've VS 2010 and recently installed WCF RIA Services V1.0. For testing I have created a new Silverligh Business project but now every now and then when I rebuild the solution I receive the following error: Does anybody know why I get this? Thanks Error 1 The "CreateRiaClientFilesTask" task failed unexpectedly.

• UnauthorizedAccessException on MemoryMappedFile in C# 4.

  - by Kevin Nisbet

  Hey, I wanted to play around with using a MemoryMappedFile to access an existing binary file. If this even at all possible or am I a crazy person? The idea would be to map the existing binary file directly to memory for some preferably higher-speed operations. Or to atleast see how these things worked. using System.IO.MemoryMappedFiles; System.IO.FileInfo fi = new System.IO.FileInfo(@"C:\testparsercap.pcap"); MemoryMappedFileSecurity sec = new MemoryMappedFileSecurity(); System.IO.FileStream file = fi.Open(System.IO.FileMode.Open, System.IO.FileAccess.ReadWrite, System.IO.FileShare.ReadWrite); MemoryMappedFile mf = MemoryMappedFile.CreateFromFile(file, "testpcap", fi.Length, MemoryMappedFileAccess.Read, sec, System.IO.HandleInheritability.Inheritable, true); MemoryMappedViewAccessor FileMapView = mf.CreateViewAccessor(); PcapHeader head = new PcapHeader(); FileMapView.Read<PcapHeader>(0, out head); I get System.UnauthorizedAccessException was unhandled (Message=Access to the path is denied.) on the mf.CreateViewAccessor() line. I don't think it's file-permissions, since I'm running as a nice insecure administrator user, and there aren't any other programs open that might have a read-lock on the file. This is on Vista with UAC disabled. If it's simply not possible and I missed something in the documentation, please let me know. I could barely find anything at all referencing this feature of .net 4.0 Thanks!

• Detect blocked popup in Chrome

  - by Andrew

  I am aware of javascript techniques to detect whether a popup is blocked in other browsers (as described in the answer to this question). Here's the basic test: var newWin = window.open(url); if(!newWin || newWin.closed || typeof newWin.closed=='undefined') { //POPUP BLOCKED } But this does not work in Chrome. The "POPUP BLOCKED" section is never reached when the popup is blocked. Of course, the test is working to an extent since Chrome doesn't actually block the popup, but opens it in a tiny minimized window at the lower right corner which lists "blocked" popups. What I would like to do is be able to tell if the popup was blocked by Chrome's popup blocker. I try to avoid browser sniffing in favor of feature detection. Is there a way to do this without browser sniffing? Edit: I have now tried making use of newWin.outerHeight, newWin.left, and other similar properties to accomplish this. Google Chrome returns all position and height values as 0 when the popup is blocked. Unfortunately, it also returns the same values even if the popup is actually opened for an unknown amount of time. After some magical period (a couple of seconds in my testing), the location and size information is returned as the correct values. In other words, I'm still no closer to figuring this out. Any help would be appreciated.

• export data from WCF Service to excel

  - by Dave

  I need to provide an export to excel feature for a large amount of data returned from a WCF web service. The code to load the datalist is as below: List<resultSet> r = myObject.ReturnResultSet(myWebRequestUrl); //call to WCF service myDataList.DataSource = r; myDataList.DataBind(); I am using the Reponse object to do the job: Response.Clear(); Response.Buffer = true; Response.ContentType = "application/vnd.ms-excel"; Response.AddHeader("Content-Disposition", "attachment; filename=MyExcel.xls"); StringBuilder sb = new StringBuilder(); StringWriter sw = new StringWriter(sb); HtmlTextWriter tw = new HtmlTextWriter(sw); myDataList.RenderControl(tw); Response.Write(sb.ToString()); Response.End(); The problem is that WCF Service times out for large amount of data (about 5000 rows) and the result set is null. When I debug the service, I can see the window for saving/opening the excel sheet appear before the service returns the result and hence the excel sheet is always empty. Please help me figure this out.

• SPException: Catastrophic failure (Exception from HRESULT: 0x8000FFF (E_UNEXPECTED) in Sharepoint

  - by BeraCim

  I've been trying to programmatically copy custom content type and its custom columns from one web to another for some time now, and I always get different errors or exceptions every time. After yet more tries, I received more strange and cryptic exception from Sharepoint after clicking onto a newly copied custom column in a custom content type.

• Path Not Found error when opening VB6 project from a shared folder on Virtual PC 2007 (XP sp3)

  - by law1185

  I currently work on a small software team that primarily maintains legacy software. I am trying to set up a VirtualPC that we can use to do this maintenance. Specifically, I would like to be able to debug and run VB6 web apps from a folder on the host pc. My constraints are as follows: The VirtualPC will not be registered on the domain. The server that hosts our Subversion repository does not run the subversion service so the only way to interact with the repository is through "file:\\", which requires domain authentication. It is not possible to debug/run VB6 web apps that are located on mapped network drives, because IIS requires that the VirtualPC be on the same domain as the network drive I would like to avoid having to copy the folder from the host pc to the VirtualPC and then copying it back in order to have the latest revision from Subversion So, I am trying to use VirtualPC's shared folder feature to share the host machine's Subversion directory and open the project in VB6 on the VirtualPC. Problem is that Visual Basic throws the error: "Path not found: '\\C:\\Subversion\Path\Project.vbp'" when I try to open it. Folder C:\Subversion on the host machine is mapped to G: on the VirtualPC. If anyone can help me resolve this error or find some other way to accomplish this, I would be deeply grateful. Oh, both host and virtual OS is Windows XP sp3. Using VB 6.0, IIS v5.1. I can manipulate files in the shared directory freely from the VirtualPC ie. copy, paste, delete, etc. Edit: Link to screenshot: http://img190.imageshack.us/img190/5439/vpcscreen.png

• SharePoint: You cannot grant limited access permission level

  - by chiccodoro

  In my team, we implemented some UI to set user access rights (assign/revoke permission levels) on a certain SharePoint list. The UI supplies a "undo" feature: If you change the rights over the UI, you can restore the rights the user had before by clicking "undo". Now there is a problem if the user had the "Limited Access" permission level: This permission level is removed when you do a change over the UI. When trying to Undo, the permission level should be added again, which leads to a You cannot grant a user the limited access permission level. I've read that SharePoint grants that right automatically when a user gets access to some entity beneath the site. Still I can revoke the right manually, but then I cannot re-grant it. Is there a proper way I could work around that? My thoughts: Did I get it right that this "limited access" is granted by SharePoint on the site level only? So, do all the lists beneath the site only contain that permission level "accidentally" because they inherit it? Does that permission level have any effect at all on a list, or does it only apply to the site itself? So, would it be save to just remove it from a list and do not add it anymore when the user clicks "undo", since it has no effect anyway? (My UI always works on list / list item level, never on the whole site/web).

• What are some good/reputable/widely-used libraries written in VB.NET?

  - by Dan Tao

  Generally speaking, when VB.NET and C# are compared, there is a lot of strong support for C#, accompanied by some bashing of VB.NET until a respected developer comes along and acts as The Voice Of Reason, pointing out that while VB prior to VB.NET had its fair share of issues, VB.NET is really a very strong, fully OOP language that is, feature-wise, right about on par with C# (with the exception of certain things like a full-bodied lamba syntax [pre-VB10] or the yield keyword, as many C# faithfuls are quick to point out). I myself, having written plenty of code in both VB.NET and C#, fall squarely in the "I prefer C#, but don't consider VB.NET any less of a language" camp. However, one thing I have noticed is that when it comes to respected and/or widely-used libraries for .NET, everyting is written in C#. Or at least that's been my impression. This strikes me as a little strange because, aside from the abovementioned sprinkling of nice features (in particular the yield keyword), I tend to view the VB.NET/C# divide as primarily a matter of personal taste. Obviously, plenty of developers prefer C#. But I personally know some developers (good ones) who prefer VB.NET, which would lead me to suspect that surely some libraries (good ones) would be written in VB.NET. They must be out there, and I just haven't found them. What are some good libraries that've been written in VB.NET? The best would be open source, as that would allow interested developers to take a look at some good VB.NET code and see how effective the language can be when used properly. But I'd be interested to know about any libraries at all, particularly reputable ones.

• Printer Redirection from 2003 Terminal Server to 2008 Terminal Server

  - by xmaveric

  Our environment is a terminal server cluster (Win2003 servers) that everyone connects to do do their work. I have set up a new Win2008 R2 machine with the intention of using it to publish our main application to the TS farm. The idea was to keep this server dedicated to one application to avoid driver/dll conflicts with other software. I created a RemoteApp on the new server and made an .rdp file and placed it on the desktop of our TS farm servers. The problem I am running into is that when I connect to the RemoteApp, it doesn't show the printers that are installed on the TS server I am connecting from. We have over 20 printers installed on our TS servers, each with different drivers and permissions. I really do not want to reinstall all of these on the RemoteApp server so I was hoping Printer Redirection would handle this. It would appear that because the RDP client for Server 2003 x64 is 6.0, that version doesn't support the Easy Print feature (requires 6.1). I can't find any newer version on the MS site to download for Win2003 x64. How can I get the printers on the TS farm machine to redirect so they are viewed by the RemoteApp machine?

• SQL Server Management Studio – tips for improving the TSQL coding process

  - by kristof

  I used to work in a place where a common practice was to use Pair Programming. I remember how many small things we could learn from each other when working together on the code. Picking up new shortcuts, code snippets etc. with time significantly improved our efficiency of writing code. Since I started working with SQL Server I have been left on my own. The best habits I would normally pick from working together with other people which I cannot do now. So here is the question: What are you tips on efficiently writing TSQL code using SQL Server Management Studio? Please keep the tips to 2 – 3 things/shortcuts that you think improve you speed of coding Please stay within the scope of TSQL and SQL Server Management Studio 2005/2008 If the feature is specific to the version of Management Studio please indicate: e.g. “Works with SQL Server 2008 only" Thanks EDIT: I am afraid that I could have been misunderstood by some of you. I am not looking for tips for writing efficient TSQL code but rather for advice on how to efficiently use Management Studio to speed up the coding process itself. The type of answers that I am looking for are: use of templates, keyboard-shortcuts, use of IntelliSense plugins etc. Basically those little things that make the coding experience a bit more efficient and pleasant. Thanks again

• How good is Dotfuscator Community Edition? What is "good enough obfuscator"?

  - by zendar

  I plan to release one small, low priced utility. Since this is more hobby than business, I planned to use Dotfuscator Community Edition that is shipped with VS2008. How good is it? I could also use definition of "good enough obfuscator" - what features are missing from Dotfuscator Community Edition to make it good enough. Edit: I checked pricing on number of commercial obfuscators and they cost a lot. Is it worth it? Are commercial versions that much better protecting from reverse engineering? I'm not very afraid of my application being cracked (it will be disappointing if application is so bad that no one is interested in cracking it). It's not heavily protected anyway, not overly complex serial key and licence checks on few places in code. It just bugs me that without obfuscation, somebody can easily get source code, rebrand it and sell it as its own. Does this happens a lot? Edit 2: Can somebody recommend commercial obfuscator. I found lots of them, all of them are expensive, some even don't have price listed on web site. Feature wise, all products seem more or less similar. What is minimal set of features obfuscator should have?

• Grep failing with Emacs (windows), and GnuWin32 Grep

  - by Andy

  Hi, I've downloaded and installed the GnuWin32 tools, and added the grep executables to the Emacs bin. I've also, for what its worth, added the GnuWin32 bin folder to my Path variable. Problem is though, when I try and run with suggested grep commands, I always get: Grep exited abnormally with code 53 at Wed Feb 24 17:16:12 For the life of me, I can't find any reference to error code 53 anywhere! :( I've tried the exact examples on a number of websites for example, when I enter: M-x grep <ret> It comes up with Run grep (like this): grep -n Which is fine, but I have no idea of what parameters it expects. I've tried some in some tuorials, but I get error code 53 again! One of the things I've tried is straight from the emacs wiki (http://www.emacswiki.org/emacs/GrepMode#toc2) (maybe not for the windows version though?) and it says to try this command: M-x grep -n -e setq ~/.emacs Which I've tried and I get: -*- mode: grep; default-directory: "c:/[My Directory]/" -*- Grep started at Wed Feb 24 17:30:47 grep -n -e setq ~/.emacs NUL Grep exited abnormally with code 53 at Wed Feb 24 17:30:47 So frustrating as this is meant to be a powerful feature of Emacs and I'm really trying to learn it as I've heard good things about it! Any help would be appreciated! :) Andy UPDATE From the suggestion below, I've tried it via command line and it seems to work fine, perhaps there some config I'm UPDATE I've found the command M-x Occur which seems to do much the same as I would image grep does. Are there many extra benefits to using grep over occur if I can't get this working?

• Why is jQuery so widely adopted versus other Javascript frameworks?

  - by Andrew Moore

  I manage a group of programmers. I do value my employees opinion but lately we've been divided as to which framework to use on web projects. I personally favor MooTools, but some of my team seems to want to migrate to jQuery because it is more widely adopted. That by itself is not enough for me to allow a migration. I have used both jQuery and MooTools. This particular essay tends to reflect how I feel about both frameworks. jQuery is great for DOM Manipulation, but seem to be limited to helping you do that. Feature wise, both jQuery and MooTools allow for easy DOM Selection and Manipulation: // jQuery $('#someContainer div[class~=dialog]') .css('border', '2px solid red') .addClass('critical'); // MooTools $('#someContainer div[class~=dialog]') .setStyle('border', '2px solid red') .addClass('critical'); Both jQuery and MooTools allow for easy AJAX: // jQuery $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); // MooTools (Using shorthand notation, you can also use Request.HTML) $('#someContainer div[class~=dialog]') .load('/DialogContent.html'); Both jQuery and MooTools allow for easy DOM Animation: // jQuery $('#someContainer div[class~=dialog]') .animate({opacity: 1}, 500); // MooTools (Using shorthand notation, you can also use Fx.Tween). $('#someContainer div[class~=dialog]') .set('tween', {duration: 500}) .tween('opacity', 1); jQuery offers the following extras: Large community of supporters Plugin Repository Integration with Microsoft's ASP.NET and VisualStudio Used by Microsoft, Google and others MooTools offers the following extras: Object Oriented Framework with Classic OOP emulation for JS Extended native objects Higher consistency between browsers for native functions support. More easy code reuse Used by The World Wide Web Consortium, Palm and others. Given that, it seems that MooTools does everything jQuery does and more (some things I cannot do in jQuery and I can in MooTools) but jQuery has a smaller learning curve. So the question is, why did you or your team choose jQuery over another JavaScript framework? Note: While I know and admit jQuery is a great framework, there are other options around and I'm trying to take a decision as to why jQuery should be our choice versus what we use right now (MooTools)?

• Sharepoint/WSS Reporting Services Integration woes

  - by mhollers

  after a number of failed attempts i seem to have successfully installed the Reporting services add-in to my WSS farm. However, I seem to be missing most of the enhanced functionality eg no report library template, no report center site template. the only additional functionality available is the report viewer web part. background: 2 server WSS 3.0 farm with CA (Central admin) WFE (web front end) and reporting services addin installed on 1, and SQL05 SP2 with Reporting services (RS) and all databases installed on other. I have a VM environment set up and have rolled this back and repeated a number of times. I have configured RS within CA and activated 'Report Server INtegration Feature'. Within the 'site settings' I have a 'Reporting Services' heading with a 'manage shared schedules' item/link, not sure if there should be other options? I was of the understanding that to view reports within sharepoint i could either create a new site using the 'report center' template or add a report library to an existing site, neither of which seems available I am at a loss as to what to do, as all online information seems to do with dealing with installation issues/errors, which i seem to have eventually got past

• FileNotFoundException when running WiX CustomAction with COMAdmin interop

  - by dabcabc

  I am trying to create a WiX custom action which will allow me to shutdown and clear down a COM+ package as part of an upgrade installation, or create and configure a new COM+ package as part of the initial installation. I previously had this running as a CustomAction within a standard Visual Studio MSI but this only allows the custom action to be executed after the files have been copied - which will fail as the package will still be running. The COMAdmin.dll has been added as a reference to the CustomAction project and is set CopyLocal=true. In the bin folder for the custom action project the Interop.COMAdmin.dll is present. The answer to this question seems to suggest that it should work. I am getting the following exception within the MSI log when trying to install: MSI (s) (C4:04) [10:40:34:205]: Invoking remote custom action.

• How can I use Window.ShowActivated = false with Maximized window?

  - by Anthony Brien

  I have an application that has a splash screen shown before I create my main window. I want to avoid the main window stealing the focus when it gets created if the user has focused another application while the splash screen was shown. My application's startup looks like this: private void Application_Startup(object sender, StartupEventArgs e) { SplashScreenService.Start(); // Initializing stuff... ... // Ready to open the main window. MainWindow mainWindow = MainWindow(); mainWindow.ShowActivated = SplashScreenService.HasFocus(); mainWindow.ShowDialog(); } To prevent the main window from getting activated, I'm setting Window.ShowActivated to false, only if the splash screen has lost the focus. But this causes an exception: InvalidOperationException: Cannot show Window when ShowActivated is false and WindowState is set to Maximized. Indeed, my MainWindow sets the WindowState to Maximized (restored from previous session settings). I don't understand why there is such a limitation with the ShowActivated feature. I couldn't find any documentation about this issue. I tried forcing WindowState to Normal when ShowActivated is false, and it prevents the exception, but it also activates the window! Maybe changing the window state actually causes an activation? Is there a trick I can use to work around this? I want to restore my main window in a maximized state, and not have the main window steal focus away from other applications if the user has focused away from my app during the splash screen.

• NAudio demos not working anymore

  - by Kurru

  I just tried to run the NAudio demos and I'm getting a weird error: System.BadImageFormatException: Could not load file or a ssembly 'NAudio, Version=1.3.8.0, Culture=neutral, PublicKeyToken=null' or one o f its dependencies. An attempt was made to load a program with an incorrect form at. File name: 'NAudio, Version=1.3.8.0, Culture=neutral, PublicKeyToken=null' at NAudioWpfDemo.AudioGraph..ctor() at NAudioWpfDemo.ControlPanelViewModel..ctor(IWaveFormRenderer waveFormRender er, SpectrumAnalyser analyzer) in C:\Users\Admin\Downloads\NAudio-1.3\NAudio-1-3 \Source Code\NAudioWpfDemo\ControlPanelViewModel.cs:line 23 at NAudioWpfDemo.MainWindow..ctor() in C:\Users\Admin\Downloads\NAudio-1.3\NA udio-1-3\Source Code\NAudioWpfDemo\MainWindow.xaml.cs:line 15 WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\M icrosoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure lo gging. To turn this feature off, remove the registry value [HKLM\Software\Microsoft\Fus ion!EnableLog]. Since the last time I used NAudio demos I have changed from 32bit Windows XP to 64bit Windows 7. Would this cause this issue? Its very annoying as I was about to try my hand at audio in C# again

• Why does Silverlight 4 ClientHttp WebRequest prompt the user for a login and password?

  - by James Cadd

  One of the new features of the client http stack in Silverlight 4 is the ability to supply network credentials. When I use this feature Windows shows a "Windows Security" message box that prompts the user for a login and password (text in the box is "The server xx at xx requires a username and password. Warning: This server is requesting that your username and password be sent in an insecure manner (basic authentication without a secure connection)."). I'm setting the login and password as shown below so I'm not sure why this is displayed. My code is: var request = WebRequestCreator.ClientHttp.Create(new Uri("http://myserver:8080/gui/?list=1")); request.Credentials = new NetworkCredential("login", "password"); request.BeginGetResponse(new AsyncCallback(OnRequestComplete), request); If I enter the username and password into the messagebox the request completes successfully. For a number of reasons I'd rather prompt the user for the login and password so I'd like to avoid the messagebox if possible. My setup is Silverlight 4 final, VS 2010 final, Windows 7 x86. The application is out of browser with elevated permissions.

• Why might changes be populated from one NSManagedObjectContext to another without an explicit merge?

  - by Mike Laurence

  I'm working on an object import feature that utilizes multiple threads/NSManagedObjectContexts, using http://www.mac-developer-network.com/columns/coredata/may2009/ as my guide (note that I am developing for iPhone). For some reason, when I save one of my contexts the other is immediately updated with the changes, even though I have commented out my calls to mergeChangesFromContextDidSaveNotification. Are there any reasons the contexts might be merging into one another without an explicit call? Here a log of what's going on: // 1.) Main context is saved with "Peter Gabriel" // 2.) Test context is created, begins with same contents as main context // 3.) Main context is inserted with "Spoon" // 4.) Test context is inserted with "Phoenix" // Contents at this point: CoreTest[4341:903] Artists in main context: ( "Peter Gabriel", "Spoon" ) CoreTest[4341:903] Artists in test context: ( "Peter Gabriel", "Phoenix" ) // 5.) testContext is saved // New contents of contexts: CoreTest[4341:903] Artists in main context: ( "Peter Gabriel", "Phoenix", "Spoon" ) CoreTest[4341:903] Artists in test context: ( "Peter Gabriel", "Phoenix" ) As you can see, the test context is saved midway through, and the main context suddenly has the new objects from the test context, even though I haven't performed the whole NSManagedObjectContextDidSaveNotification/mergeChangesFromContext combo. My understanding is that no changes will ever be merged unless done so explicitly... does anyone know what's going on here?

• How to control the download url for dotNetFx35setup.exe without using the Visual Studio bootstrapper

  - by tronda

  Previously I've used to Visual Studio 2008 setup.bin to generate a bootstrapper. I had some issues with it which were difficult to resolve and turned to dotNetInstaller. One great thing with the VS 2008 generated bootstrapper, was that I was able to control the download location for the .NET framework. By using the MSBuild task I could specify the componentsLocation: <GenerateBootstrapper ApplicationFile="$(TargetFileName)" ApplicationName="MyApp" ApplicationUrl="http://$(InstallerHost)$(DownloadUrl)" BootstrapperItems="@(BootstrapperFile)" CopyComponents="True" ComponentsLocation="Relative" OutputPath="$(OutputPath)" Path="C:\Program Files\Microsoft SDKs\Windows\v6.0A\Bootstrapper\" /> Here I'm able to use the ComponentsLocation="Relative" and the bootstrapper would download from our own web server - which is what I want. When I no longer have the VS 2008 bootstrapper, I would like to have the same feature. The new boostrapper downloads the dotNetFx35setup.exe from a defined server, but the problem is that this ".NET bootstrapper" connects to Microsoft's servers for downloading the needed packages. Trying to run the following command: dotNetFx35setup.exe /? did not show any options to control the download location. The web server will contain the package structure which the Windows SDK (v6.0A) has within the Bootstrapper\Packages directory. The structure looks like this: Packages DotNetFX DotNetFX30 DotNetFX35 DotNetFx35Client DotNetFx35SP1 ..... When I state a dependency to the .NET Framework 3.5, the DotNetFX35 directory structure gets copied into the bin/Debug directory. I've copied this directory onto the web server and it looks like this: DotNetFX35 dotNetFX20 dotNetFX30 dotNetFX35 x64 netfx35_x64.exe x86 netfx35_x86.exe dotNetMSP dotNetFx35setup.exe The other directories contains mainly MSI, MSP and MSU files. So any pointers on how to control downloading of the .NET framework. Shouldn't I use the dotNetFx35setup.exe file? If not - which should I use?

• JSF 2.0: use Enum values for selectOneMenu

  - by yournamehere

  I'm using JSF 2.0 and want to fill a selectOneMenu with the values of my Enum. A simple example: // Sample Enum public enum Gender { MALE("Male"), FEMALE("Female"); private final String label; private Gender(String label) { this.label = label; } public String getLabel() { return this.label; } } Unfortunately, i can't use Seam for my current project, which had a nice <s:convertEnum/> Tag that did most of the work. In Seam, to use the values of the Enum, i had to write the following markup (and create a factory that provides the #{genderValues}: <!-- the Seam way --> <h:selectOneMenu id="persongender" value="#{person.gender}"> <s:selectItems var="_gender" value="#{genderValues}"" label="#{_gender.label}"/> <s:convertEnum/> </h:selectOneMenu> The result is that i don't have to declare the Enum values explicitely anymore inside the markup. I know that this is not very easy in JSF <2.0, but is there any new in JSF2 to help with this issue? Or does Weld help here somehow? If there is nothing new in JSF2, what's the easiest way to do it in JSF 1.2? Or can i even integrate the Seam JSF tag and the corresponding classes of Seam to get the same feature in a JavaEE6-App (without the Seam container)?

• Embedding SWF in Powerpoint VSTO

  - by Amitd

  hi guys, I was wondering if there is someway to embed a Flash Shockwave Object or .SWF file in MS Powerpoint (Presentation) 2007 and higher version. ie inside ".pptx" formats . by embed i mean when i save the presentation,close it . i wont be needing the the .swf file again.that way i can share the Presentations with others. If i use this link Insert-Flash-Into-PowerPoint-2007,it works but when i save and close the presentation,the swf file doesnt get embeded. (Note:if i do the same with a .ppt file,it works correctly.) I know we can embed the swf inside powerpoint presentation version 2003 ie.".ppt" format. but couldn't do the same in .pptx format. Also is it possible to embed .swf file in .pptx using OpenXML format? I tried to rename the ".pptx" file to ".zip" and added the ".swf" in media folder. and then renamed it back to ".pptx",but when opened in Powerpoint,it gave error about unreadable content or corruption. I had read somewhere that its kind of strategy from MS not to provide this kind of support for Adobe Swf file / ActiveX object. and as of now the feature is not supported. Flashppt PPTX Embed not supported I tried the same with office 2010 and still the same result.it doesnt work. Anyone has any workarounds etc? Related links: Insert-Flash-Into-PowerPoint-2007 flashgeek support.microsoft Flashppt PPTX Embed not supported thx Amitd
