  • Visual Studio 2010 is asking to convert RDLC created on VS2008 to RDLC 2008 format?

    - by Junior Mayhé
    I've created my project on Visual Studio 2008, as well RDLC files on it. But now, when I open the solution on Visual Studio 2010 and want to open RDLC file, it's showing me a warning. That's a little funny. The report was created on VS2008 and VS2010 is asking to convert to 2008 format. Perhaps there was a problem on my VS2008 installation that created RDLC files using some ancient format (2005??!) The problem is, when you confirm with Ok button, do some design ajustments and run the app, it throws an error on 'Main report': ex.InnerException {"The definition of the report 'Main Report' is invalid."} [Microsoft.Reporting.DefinitionInvalidException]: {"The definition of the report 'Main Report' is invalid."} Data: {System.Collections.ListDictionaryInternal} HelpLink: null InnerException: {"The report definition is not valid.

  • Running PowerShell from MSdeploy runcommand does not exit

    - by Peter Moberg
    Im am trying to get MSDeploy to execute a PowerShell script on a remote server. This is how i execute MSDeploy: msdeploy \ -verb:sync \ -source:runCommand='C:\temp\HelloWorld.bat', \ waitInterval=15000,waitAttempts=1 \ -dest:auto,computername=$WebDeployService$Credentials -verbose HelloWorld.bat contains: echo "Hello world!" powershell.exe C:\temp\WebDeploy\Package\HelloWorld.ps1 echo "Done" The HelloWorld.ps1 only contains: Write-Host "Hello world from PowerShell!" However, it seems like PowerShell never terminates. This is the output from running the msdeploy: Verbose: Performing synchronization pass #1.

  • TF203015 The Item $/path/file has an incompatible pending change. While trying to unshelve.

    - by drachenstern
    I'm using Visual Studio 2010 Pro against Team Server 2010 and I had my project opened (apparently) as a solution from the repo, but I should've opened it as "web site". I found this out during compile, so I went to shelve my new changes and deleted the project from my local disk, then opened the project again from source (this time as web site) and now I can't unshelve my files. Is there any way to work around this? Did I blow something up? Do I need to do maintenance at the server? I found this question on SO #2332685 but I don't know what cache files he's talking about (I'm on XP :\ ) EDIT: Found this link after posting the question, sorry for the delay in researching, still didn't fix my problem Of course I can't find an error code for TF203015 anywhere, so no resolution either (hence my inclusion of the number in the title, yeah?) EDIT: I should probably mention that these files were never checked in in the first place. Does that matter? Can you shelve an unchecked item? Is that what I did wrong? EDIT: WHAP - FOUND IT!!! Use "Undo" on the items that don't exist because they show up in pending changes as checkins.

  • Exception from HRESULT: 0x80020009 (DISP_E_EXCEPTION)) in SharePoint

    - by BeraCim
    Hi all: After googling for many hours for a solution for the above Sharepoint exception, I have come to SO for help on this one... I believe the cause of me getting the above exception is because of the following code: try { using (SPSite site = new SPSite(siteId, spUserToken)) { using (SPWeb web = site.OpenWeb(webId)) { createNewSite(web); } } } createNewSite(web) changes the name and URL of "web" using AllowUnsafeUpdates, so when it comes out of the method it has been changed. My few months worth of Sharepoint developing experience suggest that that is the cause of the exception. "web" is no longer used anymore so I can comfortably null it myself. The problem here is... it didnt work: try { using (SPSite site = new SPSite(siteId, spUserToken)) { SPWeb web = null; using (web = site.OpenWeb(webId)) { createNewSite(web); if (web != null) { web = null; } } } } I believe that the original developer used the using declaration to avoid SPWeb objects from leaking. Asides that I think it is okay for me to break this pattern solely for the purpose of getting rid of that dreaded exception. So the question: what can I do to the above code to potentially fix this exception? Thanks.

  • Use Html.RadioButtonFor and Html.LabelFor for the same Model but different values

    - by Marc
    I have this Razor Template <table> <tr> <td>@Html.RadioButtonFor(i => i.Value, "1")</td> <td>@Html.LabelFor(i => i.Value, "true")</td> </tr> <tr> <td>@Html.RadioButtonFor(i => i.Value, "0")</td> <td>@Html.LabelFor(i => i.Value, "false")</td> </tr> </table> That gives me this HTML <table> <tr> <td><input id="Items_1__Value" name="Items[1].Value" type="radio" value="1" /></td> <td><label for="Items_1__Value">true</label></td> </tr> <tr> <td><input checked="checked" id="Items_1__Value" name="Items[1].Value" type="radio" value="0" /></td> <td><label for="Items_1__Value">false</label></td> </tr> </table> So I have the ID Items_1__Value twice which is - of course - not good and does not work in a browser when I click on the second label "false" the first radio will be activated. I know I could add an own Id at RadioButtonFor and refer to that with my label, but that's not pretty good, is it? Especially because I'm in a loop and cannot just use the name "value" with an added number, that would be end up in multiple Dom Ids in my final HTML markup as well. Shouldn't be a good solution for this?

  • How to bind collection to WPF:DataGridComboBoxColumn

    - by everwicked
    Admittedly I am new to WPF but I have looked and looked and can't find a solution to this problem. I have a simple object like: class Item { .... public String Measure { get; set; } public String[] Measures {get; } } Which I am trying to bind to a DataGrid with two text columns and a combo box column. For the combo box column, propery Measure is the current selection and Measures the possible values. My XAML is: <DataGridComboBoxColumn Header="Measure" Width="Auto" SelectedItemBinding="{Binding Path=Measure}" ItemsSource="{Binding Path=Measures}"/> </DataGrid.Columns> </DataGrid> The text column are displayed just fine but the combobox is not - the values are not displayed at all. The binding error is : ¨System.Windows.Data Error: 2 : Cannot find governing FrameworkElement or FrameworkContentElement for target element. BindingExpression:Path=Measures; DataItem=null; target element is 'DataGridComboBoxColumn' (HashCode=11497055); target property is 'ItemsSource' (type 'IEnumerable') How do I fix this??? Thanks

  • how to tackle this combinatorial algorithm problem

    - by Andrew Bullock
    I have N people who must each take T exams. Each exam takes "some" time, e.g. 30 min (no such thing as finishing early). Exams must be performed in front of an examiner. I need to schedule each person to take each exam in front of an examiner within an overall time period, using the minimum number of examiners for the minimum amount of time (i.e. no examiners idle) There are the following restrictions: No person can be in 2 places at once each person must take each exam once noone should be examined by the same examiner twice I realise that an optimal solution is probably NP-Complete, and that I'm probably best off using a genetic algorithm to obtain a best estimate (similar to this? http://stackoverflow.com/questions/184195/seating-plan-software-recommendations-does-such-a-beast-even-exist). I'm comfortable with how genetic algorithms work, what i'm struggling with is how to model the problem programatically such that i CAN manipulate the parameters genetically.. If each exam took the same amount of time, then i'd divide the time period up into these lengths, and simply create a matrix of time slots vs examiners and drop the candidates in. However because the times of each test are not necessarily the same, i'm a bit lost on how to approach this. currently im doing this: make a list of all "tests" which need to take place, between every candidate and exam start with as many examiners as there are tests repeatedly loop over all examiners, for each one: find an unscheduled test which is eligible for the examiner (based on the restrictions) continue until all tests that can be scheduled, are if there are any unscheduled tests, increment the number of examiners and start again. i'm looking for better suggestions on how to approach this, as it feels rather crude currently.

  • PDF hyperlinks on iPhone/iPad

    - by RoLYroLLs
    Hi, I've been looking around Google and SO and haven't quite found an answer to my question, or at least a more recent answer. I have a PDF with hyperlinks/hotspots in it and would like to display the PDF file in my own iPhone/iPad app. When the user clicks on a hyperlink/hotspot I would like the user to be taken to the appropriate location of the link (whether another page on the PDF or a webpage outside of the app). I have found many questions like this on here, but most dated over 6 moths ago. While that might not be so long ago, it kind of is in-spite of newer technologies and the probability of someone comping up with new code/way to do it. I looked into the QuartzDemo sample app and edited the PDF to have a hotspot and it does not work. Maybe the ability is there, but not implemented? I have found one app that DOES work great! The GoodReader app displays my PDF and allows the clicking of hotspots in my PDF. However, I'd like this implemented in my own app. So, has anyone been playing around with this? Anyone find a solution? Can anyone point others in a direction? Thanks for your time.

  • Visual Studio 2010 Crashes when Creating or Editing a Report (.rdlc) with the Report Designer

    - by ondesertverge
    This is an issue I had with VS 2010 RC and was hoping would be solved with the first official release. Sadly it wasn't. What I have is a number of reports originally created with VS 2008. When opening any of these for editing in VS 2010's Report Designer VS hangs for about two minutes and then shuts down. Same happens when creating a new report using the wizard. Only difference is that a dialog opens up showing a "Loading ..." message then hangs for about the same amount of time and crashes. Running devenv /log gives nothing of value. The Windows Application Event Viewer shows only this: Faulting application name: devenv.exe, version: 10.0.30319.1, time stamp: 0x4ba1fab3 Faulting module name: clr.dll, version: 4.0.30319.1, time stamp: 0x4ba1d9ef Exception code: 0xc00000fd Fault offset: 0x00001919 Faulting process id: 0xc38 Faulting And this: .NET Runtime version 2.0.50727.4927 - Fatal Execution Engine Error (6F551CF2) (0) Has anyone else experienced this and found a solution? OR -- Is there a better tool for rapidly creating decent reports within a WinForms app? Help would be greatly appreciated!

  • Limiting Number of Characters in a ContentEditable div

    - by Bill Dami
    Hi guys, I am using contenteditable div elements in my web application and I am trying to come up with a solution to limit the amount of characters allowed in the area, and once the limit is hit, attempting to enter characters simply does nothing. This is what I have so far: var content_id = 'editable_div'; //binding keyup/down events on the contenteditable div $('#'+content_id).keyup(function(){ check_charcount(content_id, max); }); $('#'+content_id).keydown(function(){ check_charcount(content_id, max); }); function check_charcount(content_id, max) { if($('#'+content_id).text().length > max) { $('#'+content_id).text($('#'+content_id).text().substring(0, max)); } } This DOES limit the number of characters to the number specified by 'max', however once the area's text is set by the jquery .text() function the cursor resets itself to the beginning of the area. So if the user keeps on typing, the newly entered characters will be inserted at the beginning of the text and the last character of the text will be removed. So really, I just need some way to keep the cursor at the end of the contenteditable area's text.

  • C# - Fill a combo box with a DataTable

    - by MrG
    I'm used to work with Java where large amounts of examples are available. For various reasons I had to switch to C# and trying to do the following in SharpDevelop: // Form has a menu containing a combobox added via SharpDevelop's GUI // --- Variables languages = new string[2]; languages[0] = "English"; languages[1] = "German"; DataSet myDataSet = new DataSet(); // --- Preparation DataTable lTable = new DataTable("Lang"); DataColumn lName = new DataColumn("Language", typeof(string)); lTable.Columns.Add( lName ); for( int i=0; i<languages.Length; i++ ) { DataRow lLang = lTable.NewRow(); lLang["Language"] = languages[i]; lTable.Rows.Add(lLang); } myDataSet.Tables.Add(lTable); // --- Handling the combobox mnuActionLanguage.ComboBox.DataSource = myDataSet.Tables["Lang"].DefaultView; mnuActionLanguage.ComboBox.DisplayMember = "Language"; One would assume to see some values in the dropdown, but it's empty. Please tell me what I'm doing wrong ;( EDIT: mnuActionLanguage.ComboBox.DataBind() is what I also found on the net, but it doesn't work in my case. SOLUTION mnuActionLanguage.ComboBox.BindingContext = this.BindingContext; at the end solved the problem!

  • How to use Tor control protocol in C#?

    - by Ed
    I'm trying to send commands to the Tor control port programmatically to make it refresh the chain. I haven't been able to find any examples in C#, and my solution's not working. The request times out. I have the service running, and I can see it listening on the control port. public string Refresh() { TcpClient client = new TcpClient("localhost", 9051); string response = string.Empty; string authenticate = MakeTcpRequest("AUTHENTICATE", client); if (authenticate.Equals("250")) response = MakeTcpRequest("SIGNAL NEWNYM", client); client.Close(); return response; } public string MakeTcpRequest(string message, TcpClient client) { client.ReceiveTimeout = 20000; client.SendTimeout = 20000; string proxyResponse = string.Empty; try { // Send message StreamWriter streamWriter = new StreamWriter(client.GetStream()); streamWriter.Write(message); streamWriter.Flush(); // Read response StreamReader streamReader = new StreamReader(client.GetStream()); proxyResponse = streamReader.ReadToEnd(); } catch (Exception ex) { // Ignore } return proxyResponse; } Can anyone spot what I'm doing wrong?

  • QGraphicsView scrolling and image scaling/cropping

    - by boohoo
    I would like to have a background image in my QGraphicsView that is always scaled (and cropped if necessary) to the size of the viewport, without scrollbars and without scrolling with the keyboard and mouse. The example below is what I am doing to scale and crop an image in the viewport, but I am using random values for the cropping that are pulled out of the aether. I would like a logical solution? MainWindow::MainWindow(QWidget *parent) : QMainWindow(parent), ui(new Ui::MainWindow) { ui->setupUi(this); scene = new QGraphicsScene(this); ui->graphicsView->resize(800, 427); // MainWindow is 800x480, GraphicsView is 800x427. I want an image that // is the size of the graphicsView. ui->graphicsView->setHorizontalScrollBarPolicy(Qt::ScrollBarAlwaysOff); ui->graphicsView->setVerticalScrollBarPolicy(Qt::ScrollBarAlwaysOff); // the graphicsView still scrolls if the image is too large, but // displays no scrollbars. I would like it not to scroll (I want to // add a scrolling widget into the QGraphicsScene later, on top of // the background image.) QPixmap *backgroundPixmap = new QPixmap(":/Valentino_Bar_Prague.jpg"); QPixmap sized = backgroundPixmap->scaled( QSize(ui->graphicsView->width(), ui->graphicsView->height()), Qt::KeepAspectRatioByExpanding); // This scales the image too tall QImage sizedImage = QImage(sized.toImage()); QImage sizedCroppedImage = QImage(sizedImage.copy(0,0, (ui->graphicsView->width() - 1.5), (ui->graphicsView->height() + 19))); // so I try to crop using copy(), and I have to use these values // and I am unsure why. QGraphicsPixmapItem *sizedBackground = scene->addPixmap( QPixmap::fromImage(sizedCroppedImage)); sizedBackground->setZValue(1); ui->graphicsView->setScene(this->scene); } I would like to know a way to scale and crop an image to the size of the QGraphicsView that will work even when I resize the QGraphicsView. Where are the 1.5 and 19 coming from?

  • Why doesn't TransactionScope work with Entity Framework?

    - by NotDan
    See the code below. If I initialize more than one entity context, then I get the following exception on the 2nd set of code only. If I comment out the second set it works. {"The underlying provider failed on Open."} Inner: {"Communication with the underlying transaction manager has failed."} Inner: {"Error HRESULT E_FAIL has been returned from a call to a COM component."} Note that this is a sample app and I know it doesn't make sense to create 2 contexts in a row. However, the production code does have reason to create multiple contexts in the same TransactionScope, and this cannot be changed. Edit Here is a previous question of me trying to set up MS-DTC. It seems to be enabled on both the server and the client. I'm not sure if it is set up correctly. Also note that one of the reasons I am trying to do this, is that existing code within the TransactionScope uses ADO.NET and Linq 2 Sql... I would like those to use the same transaction also. (That probably sounds crazy, but I need to make it work if possible). http://stackoverflow.com/questions/794364/how-do-i-use-transactionscope-in-c Solution Windows Firewall was blocking the connections to MS-DTC. using(TransactionScope ts = new System.Transactions.TransactionScope()) { using (DatabaseEntityModel o = new DatabaseEntityModel()) { var v = (from s in o.Advertiser select s).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> By commenting out this section, it works using (DatabaseEntityModel o = new DatabaseEntityModel()) { //Exception on this next line var v = (from s1 in o.Advertiser select s1).First(); v.AcceptableLength = 1; o.SaveChanges(); } //-> ts.Complete(); }

  • iPhone: Software Development And Distribution

    - by xsl
    I have a few quick questions about the iPhone software development. I did some research about the topic, but there are a few specific things I would like to ask here, because I will have to estimate the cost of the required hardware and software, before I am allowed to buy anything. I never did any Mac development nor have I ever owned an iPhone, so needless to say this is quite hard for me. I will buy an iMac mini with 2 GB RAM for iPhone development. I will have to use it at the same time as my regular PC, but the majority of the time I won't use the Mac at all. Do I have to buy an additional monitor, a mouse and a keyboard or is there a better solution? I will have to port a C library to the iPhone platform and develop an iPhone application that uses the ported library. Do I need anything else than the iPhone SDK to do this? If I use an external library (see above), can I test the application with the integrated emulator, or is it recommend to buy the device? In a later phase of the project I will have to buy an iPhone, but I will have to wait until the iPhone 4 is released here in Europe, because the application requires a camera. In addition to this I will have to send data to a remote webservice. Aside from these two things I don't require any other features. Can I just buy the iPhone online from another country (the iPhones here are sim locked), or should I buy one with a contract? When the application is ready, it will be installed on a few iPhones owned by our customer. Because of security reasons it is crucial that there is no third party involved in this process (i.e. the application should not be distributed on the app store). Is this possible?

  • How to fix the endless printing loop bug in Nevrona Rave

    - by Sean B. Durkin
    Nevrona Designs' Rave Reports is a Report Engine for use by Embarcadero's Delphi IDE. This is what I call the Rave Endless Loop bug. In Rave Reports version 6.5.0 (VCL10) that comes bundled with Delphi 2006, there is a nortorious bug that plagues many Rave report developers. If you have a non-empty dataset, and the data rows for this dataset fit exactly into a page (that is to say there are zero widow rows), then upon PrintPreview, Rave will get stuck in an infinite loop generating pages. This problem has been previously reported in this newsgroup under the following headings: "error: generating infinite pages"; Hugo Hiram 20/9/2006 8:44PM "Rave loop bug. Please help"; Tomas Lazar 11/07/2006 7:35PM "Loop on full page of data?"; Tony Chistiansen 23/12/2004 3:41PM reply to (3) by another complainant; Oliver Piche "Endless lopp print bug"; Richso 9/11/2004 4:44PM In each of these postings, there was no response from Nevrona, and no solution was reported. Possibly, the problem has also been reported on an allied newsgroup (nevrona.public.rave.reports.general), to wit: 6. "Continuously generating report"; Jobard 20/11/2005 Although it is not clear to me if (6) is the Rave Endless loop bug or another problem. This posting did get a reply from Nevrona, but it was more in relation to multiple regions ("There is a problem when using multiple regions that go over a page-break.") than the problem of zero widows.

  • ASP.NET MVC in a subfolder (only) on godaddy

    - by Anthony Potts
    Okay, I have read many of the routing posts concerning putting asp.net mvc on godaddy. However, I have not come to a solution to my current problem. I am trying to publish an ASP.NET MVC application to a subfolder on godaddy. I have upgraded the account to use IIS 7 and I have included the MVC dlls in \bin\ deployment method. However, I suspect that my route is not correct. Currently, my routes are set up with the standard out of the box route: public static void RegisterRoutes(RouteCollection routes) { routes.IgnoreRoute("{resource}.axd/{*pathInfo}"); routes.MapRoute( "Default", // Route name "{controller}/{action}/{id}", // URL with parameters new { controller = "Home", action = "Index", id = "" } // Parameter defaults ); } I have a subdomain set up so that it looks like office.domain.com. The subdomain is pointing at a folder "/office/" which is right off the root folder. (There is not an MVC application installed in the root folder). All of my application has been placed in this 'office' folder. When I hover over the links however, the 'office' portion shows up in the link as well. e.g. Hovering over a link to the customer controller, index action yields "office.domain.com/office/Customer" as the target. This link then gets a 404 when I attempt to go to it. What should my route be to fix this? Is there something I have neglected in setting up the subdomain in godaddy? Is this something I just can't do in godaddy's domain management "tool". Do I need to set up a virtual directory for this instead of just a directory? Update: I changed the IIS settings in godaddy to use integrated pipeline mode, per this discussion and I am no longer getting 404 errors. The application worked just fine as suggested it would.

  • Selecting text in mobile Safari on iPhone

    - by Goldy
    I'm trying to make it easy for an iphone user to copy some text to the clipboard in mobile safari. As in the usual "touch-hold-copy". There is a specific bit of text I want to a user to copy. I have full choice of the html markup in which to wrap the text. How can I make it easy, rather than abitrary? For instance: Is there a way to "select all" the text upon touch-down using javascript? Then a user could just continue to touch-hold and then choose copy? Is there a way to bring up the "select all" option? Like you can when typing in a text box? After which they can choose copy? If there's no javascript solution, how can I arrange the html to help Safari select the right bit of text easily? As opposed to just a word, or a wrapping div? I've tried onFocus="this.select()" for various elements, none seem to work. Also tried onClick. Those who have tried to port a site that uses ZeroClipboard to the iPhone might have some ideas. Cheers

  • UIImagePicker on full screen on iPad

    - by Archip
    For my tests, I need to create a simple app on the iPad to step 1. loads an image from the Photo library (UIImagePickerController). step 2. Then, this image is converted into texture and displayed into an OpenGL ES view. I started to define the app with the XCode Open GL ES template. Step 2 is Okay. But I have a problem launching the UIImagePickerController (step 1). On iPad, to create a UIImagePickerController, we need to use a UIPopoverController. But to create a UIPopover, we need to attach it to a content view controller In my app, I dont want to define a specific view controller (Navigation or SplitView or TabBar...). I just need to have the UIImagePicker displayed on full screen when launching the app. I am looking for a programatical solution with a minimum of lines of code added from the Open GL ES iPad template, to perform step 1 (step 2 is okay for me). any code available? Thank you for your help Seb

  • c# Named Pipe Asynchronous Peeking

    - by KJ Tsanaktsidis
    Hey all, I need to find a way to be notified when a System.IO.Pipe.NamedPipeServerStream opened in asynchronous mode has more data available for reading on it- a WaitHandle would be ideal. I cannot simply use BeginRead() to obtain such a handle because it's possible that i might be signaled by another thread which wants to write to the pipe- so I have to release the lock on the pipe and wait for the write to be complete, and NamedPipeServerStream doesnt have a CancelAsync method. I also tried calling BeginRead(), then calling the win32 function CancelIO on the pipe if the thread gets signaled, but I don't think this is an ideal solution because if CancelIO is called just as data is arriving and being processed, it will be dropped- I still wish to keep this data, but process it at a later time, after the write. I suspect the win32 function PeekNamedPipe might be useful but i'd like to avoid having to continuously poll for new data with it. In the likley event that the above text is a bit unclear, here's roughly what i'd like to be able to do... NamedPipeServerStream pipe; ManualResetEvent WriteFlag; //initialise pipe lock (pipe) { //I wish this method existed WaitHandle NewDataHandle = pipe.GetDataAvailableWaithandle(); Waithandle[] BreakConditions = new Waithandle[2]; BreakConditions[0] = NewDataHandle; BreakConditions[1] = WriteFlag; int breakcode = WaitHandle.WaitAny(BreakConditions); switch (breakcode) { case 0: //do a read on the pipe break; case 1: //break so that we release the lock on the pipe break; } }

  • asp.net ajax control toolkit combobox displays incorectly when in fieldset with style of position:re

    - by Jon P
    I currently have an Instance of the ASP.net ajax control toolkit combo box residing in a field set with a style of position:releative applied. The control also sits in a very plain table (please no comments about using tables for lay-out, I know it is evil and try to avoid it). There are two problems with the display of the list: The list does not sit flush with the text box. In I.E. 7 (which is the majority of my target audience, intranet where IE7 is the company standard) the list display about 10px below the fieldset, which is what the bottom margin of the fieldset is set to. In FF 2.0 the list sits sinificantly lower and off-set to the right. Below the filed set there is more content in a div, also with a style of position:relative applied. The list from the combo box displays behind the content of this div, which is obviouly an issue. Removing position:releative from the fieldset resolves the display issue of the combo box, but results in other unwanted display side effects. My interim workaround is to specifically restyle this fieldset without the position:absolute style, but I'm hoping for a better solution. Thanks

I found Obout while googling. I never heard about them and never seen fellow members telling me such name except Telerik, ComponentOne, NetAdvantage. These are the famous names we heard but no this one. But, the controls give a positive feeling. But as two things matter always when you are buying some services: How good are their customer support? and How much feasible their price is? Another, How quickly they release patches/updates? As, what if we find a bug or an error during development what will gonna happen? Do they provide a quick solution for this? I hope you understand my query. I'm bit confused making a decision here. I need your assistance, experience and feedback. Please, assist! Thanks.

  • Unknown Build Error using WPF Toolkit

    - by Tom Allen
    I installed the Feb 2010 WPF Toolkit as I'm interested in evaluating the AutoCompleteBox control and I'm having extremely limited success. I can get the control to work, but as soon as I try and set any of it's properties in XAML, I get the following: Unknown build error, 'Cannot resolve dependency to assembly 'WPFToolkit, Version=3.5.40128.1, Culture=neutral, PublicKeyToken=31bf3856ad364e35' because it has not been preloaded. When using the ReflectionOnly APIs, dependent assemblies must be pre-loaded or loaded on demand through the ReflectionOnlyAssemblyResolve event. I've been testing this on a blank WPF window in a new solution. I'm guessing I'm just missing a reference or something... Here's the XAML (I've added nothing to the .xaml.cs): <Window x:Class="WpfToolkitApplication.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:toolkit="clr-namespace:System.Windows.Controls;assembly=System.Windows.Controls.Input.Toolkit" Title="Window1" Height="300" Width="300"> <Grid> <toolkit:AutoCompleteBox Height="25"/> </Grid> </Window> The only reference I've added is System.Windows.Controls.Input.Toolkit. Any ideas?

  • How can I beta test web Perl modules under Apache/mod_perl on production web server?

    - by DVK
    We have a setup where most code, before being promoted to full production, is deployed in BETA mode - meaning, it runs in full production environment (using production database - usually production data; and production web server). We call that stage BETA testing. One of the main requirements is that BETA code promotion to production must be a simple "cp" command from beta to production directory - no code/filename changes. For non-web Perl code, achieving seamless BETA test is quite doable (see details here): Perl programs live in a standard location under production root (/usr/code/scripts) with production perl modules living under the same root (/usr/code/lib/perl) The BETA code has 100% same code paths except under beta root (/usr/code/beta/) A special module manipulates @INC of any script based on whether the script was called from /usr/code/scripts or /usr/code/test/scripts, to include beta libraries for beta scripts. This setup works fine up till we need to beta test our web Perl code (the setup is EmbPerl and Apache/mod_perl). The hang-up is as follows: if both a production Perl module and BETA Perl module have the same name (e.g. /usr/code/lib/perl/MyLib1.pm and /usr/code/beta/lib/perl/MyLib1.pm), then mod_perl will only be able to load ONE of these modules into memory - and there's no way we are aware of for a particular web page to affect which version of the module is currently loaded due to concurrency issues. Leaving aside the obvious non-programming solution (get a bloody BETA web server) which for political/organizational reasons is not feasible, is there any way we can somehow hack around this problem in either Perl or mod_perl? I played around with various approaches to unloading Perl modules that %INC has listed, but the problem remains that another user might load a beta page at just the right (or rather wrong) moment and have the beta module loaded which will be used for my production page.

  • Split WPF Style XAML Files

    - by anon
    Most WPF styles I have seen are split up into one very long Theme.xaml file. I want to split mine up for readability so my Theme.xaml looks like this: <ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"> <ResourceDictionary.MergedDictionaries> <ResourceDictionary Source="/PresentationFramework.Aero;v3.0.0.0;31bf3856ad364e35;component/themes/aero.normalcolor.xaml"/> <ResourceDictionary Source="Controls/Brushes.xaml"/> <ResourceDictionary Source="Controls/Buttons.xaml"/> ... </ResourceDictionary.MergedDictionaries> </ResourceDictionary> The problem is that this solution does not work. I have a default button style which is BasedOn the default Aero style for a button: <Style x:Key="{x:Type Button}" TargetType="{x:Type Button}" BasedOn="{StaticResource {x:Type Button}}"> <Setter Property="FontSize" Value="14"/> ... </Style> If I place all of this in one file it works but as soon as I split it up I get StackOverflow exceptions because it thinks it is BasedOn itself. Is there a way around this? How does WPF add resources when merging resource dictionaries?
