  • WPF Ignoring ProgressBar Style

    - by Nidonocu
    Following a problem in WPF 4 where the default ProgressBar template has an off-white highlight applied causing it to dull the foreground colour, I decided to extract the template and manually edit the values to white. After doing this, I put the template as a style in App.xaml for global use and the Visual Studio designer began to use it right away. However, when I run my app, the default style is still being applied: I then tried setting the style specifically using a key, then even having it as an inline style and finally as a inline template without a wrapping style for the specific progress bar and it is still ignored. What's going wrong? Current Code for progress bar: <ProgressBar Grid.Column="1" Grid.Row="2" Height="15" Width="355" Margin="0,0,0,7" IsIndeterminate="{Binding ProgressState, FallbackValue=False}" Visibility="{Binding ProgressVisibility, FallbackValue=Collapsed}" Value="{Binding ProgressValue, Mode=OneWay, FallbackValue=100}" Foreground="{Binding ProgressColor,FallbackValue=Red}"> <ProgressBar.Template> <ControlTemplate> <Grid Name="TemplateRoot" SnapsToDevicePixels="True"> <Rectangle RadiusX="2" RadiusY="2" Fill="{TemplateBinding Panel.Background}" /> ...

  • WCF Web Service Gives 404 error in Azure

    - by landyman
    I'm new to using WCF and Azure, but I have a WCF Web Service that works correctly when debugging in Visual Studio. I set the startup project to Azure, and I get 404 errors for any URL I try related to the service. Here is what I think is relavant code: From IWebService.cs [OperationContract] [WebGet(UriTemplate = "GetData/Xml?value={value}", ResponseFormat=WebMessageFormat.Xml)] string GetDataXml(string value); and from Web.config: <system.serviceModel> <services> <service name="WebService" behaviorConfiguration="WebServiceBehavior"> <!-- Service Endpoints --> <endpoint address="" binding="webHttpBinding" contract="IWebService" behaviorConfiguration="WebEndpointBehavior"></endpoint> <endpoint address="ws" binding="wsHttpBinding" contract="IWebService"/> <endpoint address="mex" binding="mexHttpBinding" contract="IMetadataExchange"/> </service> </services> <behaviors> <serviceBehaviors> <behavior name="WebServiceBehavior"> <serviceMetadata httpGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true"/> </behavior> </serviceBehaviors> <endpointBehaviors> <behavior name="WebEndpointBehavior"> <webHttp/> </behavior> </endpointBehaviors> </behaviors> </system.serviceModel> I have tried changing the binding to 'basicHttpBinding', but that had no luck. Thanks in advance for any help!

  • 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.

  • [PHP] Making a good singleton registry class structure which hold your objects

    - by Saif Bechan
    I am working on a web application in PHP. I have a singleton class called registry. This class will hold all the objects i need throughout my application, such as loader classes, template classes, database, classes, etc. When an object of the registry class is created I send it an array with the classes it need to load: // Create the registry $registry = registry::singleton(); // Store those core objects $registry->storeObjects(Array('session','db','page','template','errors')); In this example I only put some of the classes, to get the basic idea. Now I have some classes in the registry that use each other. For example the 'errors' object uses the 'page' object. Now I was wondering if it is a good practice to make an instance of the registry object in the errors object. Like this; class errors{ private $registry; public function __construct(){ $this->registry = registry::singleton(); } } So there is an instance of the registry object, inside an object of the registry object. This does not sound like a good idea to me. Anyone have a suggestion how to model such a thing?

  • Creating a Sharepoint Development Environment from an Existing Production Environment

    - by Starky
    I have very little experience using Sharepoint but a good amount using Visual Studio 2008, SQL Server 2005, Windows Server 2003 and IIS6. I need to create a development environment for a SharePoint 2007 system that will be used internally. The system is already deployed over two servers - one of the servers simply holds the database and everything else is on the other server. We are also using WSS 3.0. I have created a Virtual Machine with all the required software including a clean installation of SharePoint Server 2007 and I wish to use this single Virtual Machine as the development environment. Right now there are no custom assemblies being used on the production server as far as I am aware. There are 3 websites, one over port 80 for user accesss, one over a custom port for central administration, and one over another custom port. Not sure what the last one is for but my blank instance of Sharepoint on my Virtual Machine also has something similar. I attempted to use the STSADM tool to backup and restore these 3 sites from my production environment to my development environment and while the operations completed succesfully, the central administration site in my development environment acted strangely and I could not access port 80 - I did not seem to have correct credentials for it. I suspected that it would not have been so simple so could I please have advice on how to create my development environment so that I can use it to deploy updates to the production one.

  • How to play non buffered .wav with MediaStreamSource implementation in Silverlight 4?

    - by kyrisu
    Background I'm trying to stream a wave file in Silverlight 4 using MediaStreamSource implementation found here. The problem is I want to play the file while it's still buffering, or at least give user some visual feedback while it's buffering. For now my code looks like that: private void button1_Click(object sender, RoutedEventArgs e) { HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(new Uri(App.Current.Host.Source, "../test.wav")); //request.ContentType = "audio/x-wav"; request.AllowReadStreamBuffering = false; request.BeginGetResponse(new AsyncCallback(RequestCallback), request); } private void RequestCallback(IAsyncResult ar) { this.Dispatcher.BeginInvoke(delegate() { HttpWebRequest request = (HttpWebRequest)ar.AsyncState; HttpWebResponse response = (HttpWebResponse)request.EndGetResponse(ar); WaveMediaStreamSource wavMss = new WaveMediaStreamSource(response.GetResponseStream()); try { me.SetSource(wavMss); } catch (InvalidOperationException) { // This file is not valid } me.Play(); }); } The problem is that after settings request.AllowREadStreamBuffer to false the stream does not support seeking and the above mentioned implementation throws an exception (keep in mind I've put some of the position setting logic into if(stream.CanSeek) block): Read is not supported on the main thread when buffering is disabled Question Is there a way to play wav stream without buffering it in advance?

  • How can I install asp.net mvc 2 on IIS7?

    - by Gary McGill
    I have developed an ASP.NET MVC 2 website, and now need to deploy it to my web server. I've overcome some hurdles already, since ASP.NET was not installed etc. but I've now got to the point where I can serve up plain content files, and if I try to hit one of my MVC URLs I get this: Could not load file or assembly 'System.Web.Mvc, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. Not surprising, that, as I've not installed MVC2. Problem is, I can't find any good information about how to install it! The Microsoft Download Center lists 3 files, none of which look promising: ASP.NET-MVC-2-RTM-Release-Notes.doc AspNetMVC2_VS2008.exe mvc2-ms-pl.zip The site doesn't bother to explain what the files actually are, but I assume that the last file is the source code. That's what it looks like, anyway. The release notes are no help whatsoever, since they're all about installing on your development machine, and indeed the name of the EXE makes it clear that that's all about Visual Studio integration too. So how do I actually deploy the darn thing? The other option linked to from Scott Gu's blog is the Microsoft Web Platform Installer. Now, I don't want to install more than just MVC2, and I already have IIS etc. set up, so this seems a bit heavy. But it's all academic, as it refuses to run on my server, saying "your system is not supported" or words to that effect. (The server is Windows Server 2008 Standard SP2, so I really don't know what it's problem is). Help! [It's ridiculous that this should be so hard - or perhaps not hard at all, but certainly a well-kept secret!]

  • Why does Adding Core Animation slow down drawing of my NSTableView?

    - by Will Goring
    I have a simple App that displays a list of items using NSTableView. There are usually about 15-25 items in the list, and the table has 10 columns, all but one of which are text (the other's an icon.) There are simple data transformers on a couple of the columns. So nothing taxing; you'd expect it to run just fine. And as it stands, it is; the app is responsive and everything draws pretty much instantly. Scrolling, changing column sizes, resizing the window; whatever you do the redraws keep up with the mouse-pointer. Tonight, I thought I'd try adding a little visual flair to the app with Core Animation (which I've never used before,) but I've found that if anything above the NSTableView in the hierarchy is set 'Wants Core Animation Layer,' then the NSTableView redraws go to hell. Scrolling is usually fine, but resizing columns or the window causes it to pick up an effect like texture tearing, where some of the rows have the new size, and some have the old one, and everything flickers horribly. It looks terrible. Basically it looks like what you'd expect if rendering the individual rows or columns was taking a long time. I've put it through Shark and, sure enough, it looks like it's spending most of its time drawing the text in the cells; what I don't understand is why that should take longer when there's a Core Animation layer involved than when there isn't - and quite noticeably longer at that. Has anyone got any ideas? Is there any Core Animation initialisation or config I've missed or something (I've literally just ticked the "Wants Core Animation Layer" box in IB)? Cheers, Will

  • StyleCop XML Documentation Header - Using 3 /// instead of 2 //

    - by Adam Jenkin
    I am using XML documentation headers on my c# files to pass the StyleCop rule SA1633. Currently, I have to use the 2 slash commenting rule to allow StyleCop to recognize the header. for example: // <copyright file="abc.ascx.cs" company="MyCompany.com"> // MyCompany.com. All rights reserved. // </copyright> // <author>Me</author> This works fine for StyleCop, however I would like to use the 3 slash commenting rule to enable visual studio to understand the comments as XML and provide the XML functionality (highlighting, auto indenting etc) /// <copyright file="abc.ascx.cs" company="MyCompany.com"> /// MyCompany.com. All rights reserved. /// </copyright> /// <author>Me</author> The problem is that when using 3 slashes, StyleCop no longer see's the header and throws the SA1633 warning. Is there anyway to configure stylecop to understand the header is contained in XML using 3 slashes? Thanks, Adam

  • Crystal Reports - "A string is required here" formula error.

    - by George Mauer
    I have a command line utility that generates one simple crystal report. I recently updated the project from .NET 1.1 to .NET 3.5 using the Visual Studio 2008 migrator and am now getting an error that I had never received before. The problem is in the work_order formula which is as follows: stringVar nvl_ship_wrk_id := "0"; stringVar nvl_ship_wrk_seq := "0"; If Not IsNull({FeedBOLInput.ShipWrkId}) Then nvl_ship_wrk_id := {FeedBOLInput.ShipWrkId}; If Not IsNull({FeedBOLInput.ShipWrkSeq}) Then nvl_ship_wrk_seq := {FeedBOLInput.ShipWrkSeq}; nvl_ship_wrk_id & " - " & nvl_ship_wrk_seq; And the error is: - InnerException {"A string is required here. Error in File C:\\...\\temp_88c50533-02c6-4973-ae06-ed0ab1a603ac {0D5E96FB-038A-41C5-93A7-A9D199961377}.rpt: Error in formula <work_order>. 'stringVar nvl_ship_wrk_id := \"0\"; ' A string is required here."} System.Exception {System.Runtime.InteropServices.COMException} Does anyone have any idea what this can be? I'm out of clues. The dataset is coming in properly - and the error seems to point to a row which merely initializes a variable.

  • Is NUnit broken with Windows7 for C++/CLI?

    - by Andy Dent
    NUnit is failing in C++/CLI with a System.IO.FileNotFoundException. I have tried my own freshly-created project, the C++/CLI sample included with NUnit and the one from CodeProject How to use NUnit to test native C++ code using Visual Studio 2008sp1 with NUnit 2.5.5 as well as 2.4.8. I installed 2.4.8 just on C:\ in case there was something weird about paths with spaces such as Program Files (x86). I have no problems with a C# sample using NUnit. in NUnit GUI, all of these C++/CLI projects encounter the same problem, on attempting to open the projects. I'd really like to use NUnit but for now have had to go back to standard Microsoft tests System.IO.FileNotFoundException...

  • Using a Mac for cross platform development?

    - by mdec
    Who uses Macs for cross-platform development? By cross platform I essentially mean you can compile to target Windows or Unix (not necessarily both at the same time). I understand that this also has a lot to do with writing portable code, but I am more interested in people's experience with Mac OS X to develop software. I understand that there are a range of IDEs to choose from, I would probably use Eclipse (I like the GCC toolchain) however Xcode seems to be quite popular. Could it be used as described above? At a pinch I could always virtualise with VirtualBox or VMware Player or parallels to use Visual Studio (or dual boot for that matter). Having said that I am open to any other suggested compilers (with preferably an IDE that uses GCC.) Also with the range of Macs available, which one would you recommend? I would prefer a laptop (as I already have a desktop) but am unsure of reasonable specifications. If you are currently using a Mac to do development, I would love to hear what you develop on your Mac and what you like and don't like about it. I would primarily be developing in C/C++/Java. I am also looking to experiment with Boost and Qt, so I'm interested in hearing about any (potential) compatibility issues. If you have any other tips I'd love you hear what you have to say.

  • SSRS for Sharepoint, Images in a report from a Sharepoint List URL?

    - by James Polhemus
    Greetings Sabios, I have several reports I run successfully where the data comes from a Sharepoint list in the form of an XML dataset. I am however having trouble with one. I have a report that pulls an image file onto the main body of the report. This data too comes from a Sharepoint list in the form of an XML dataset which sends me the URL to the jpeg or bmp or gif... whatever the case may be. I can successfully pull this off in my own Visual Studio IDE. My Local Report Server will render it as well It won't run on my Sharepoint Report Server (My MOSS runs through https while my Shartpoint Report Server is http might this matter?) When I upload it to Sharepoint and run it through the Sharepoint Report Server, I get back EVERYTHING in the report Header and Footer (dataset text and embedded Images) but just a big RED X where the Main Image should be. I have done everything the boards say: A. I made sure the Unattended Execution Account is running on the Reports Server B. I have insured the URL comes back in clean format (else the images wouldn't render locally either and they do) The report logs throw this exception: e ERROR: Throwing Microsoft.ReportingServices.Diagnostics.Utilities.ContainerTypeNotSupportedException: The target location you specified is not supported by the report server. A report definition (.rdl), report model (.smdl), resource, or shared data source (.rsds) file must be located within a library or a folder within it., ; Info: Microsoft.ReportingServices.Diagnostics.Utilities.ContainerTypeNotSupportedException: The target location you specified is not supported by the report server.

  • "If not exists" fails on SQL CE

    - by Mark Evans
    Hi I've got an unexpected problem. I'm making a script to update the schema on a SQL CE database. This won't run: if not exists ( Select column_name from information_schema.columns where column_name = 'TempTestField' and table_name = 'Inventory_Master_File' ) Alter table Inventory_Master_File add TempTestField nvarchar(10) null I think this is because I'm using stuff that isn't supported in SQL CE. Anyone know how to do this? I've tried rearranging the script and can't get anything to work. I tried "alter table ... where not exists ...". Note that the "select" part runs fine and also the "alter" part. The problem is "if not exists". I know there are some other postings regarding problems like this using SQL CE but I couldn't find an answer to this particular problem. Cheers Mark UPDATE: I've spent over an hour looking for a solution. I've found many postings asking for help with similar problems but I've still got no idea how to fix it. I really don't want to do this in C# code. I need to do this in a SQL script. I can't believe something this basic is causing so much difficulty :(

  • Single player 'pong' game

    - by Jam
    I am just starting out learning pygame and livewires, and I'm trying to make a single-player pong game, where you just hit the ball, and it bounces around until it passes your paddle (located on the left side of the screen and controlled by the mouse), which makes you lose. I have the basic code, but the ball doesn't stay on the screen, it just flickers and doesn't remain constant. Also, the paddle does not move with the mouse. I'm sure I'm missing something simple, but I just can't figure it out. Help please! Here's what I have: from livewires import games import random games.init(screen_width=640, screen_height=480, fps=50) class Paddle(games.Sprite): image=games.load_image("paddle.bmp") def __init__(self, x=10): super(Paddle, self).__init__(image=Paddle.image, y=games.mouse.y, left=10) self.score=games.Text(value=0, size=25, top=5, right=games.screen.width - 10) games.screen.add(self.score) def update(self): self.y=games.mouse.y if self.top<0: self.top=0 if self.bottom>games.screen.height: self.bottom=games.screen.height self.check_collide() def check_collide(self): for ball in self.overlapping_sprites: self.score.value+=1 ball.handle_collide() class Ball(games.Sprite): image=games.load_image("ball.bmp") speed=5 def __init__(self, x=90, y=90): super(Ball, self).__init__(image=Ball.image, x=x, y=y, dx=Ball.speed, dy=Ball.speed) def update(self): if self.right>games.screen.width: self.dx=-self.dx if self.bottom>games.screen.height or self.top<0: self.dy=-self.dy if self.left<0: self.end_game() self.destroy() def handle_collide(self): self.dx=-self.dx def end_game(self): end_message=games.Message(value="Game Over", size=90, x=games.screen.width/2, y=games.screen.height/2, lifetime=250, after_death=games.screen.quit) games.screen.add(end_message) def main(): background_image=games.load_image("background.bmp", transparent=False) games.screen.background=background_image paddle_image=games.load_image("paddle.bmp") the_paddle=games.Sprite(image=paddle_image, x=10, y=games.mouse.y) games.screen.add(the_paddle) ball_image=games.load_image("ball.bmp") the_ball=games.Sprite(image=ball_image, x=630, y=200, dx=2, dy=2) games.screen.add(the_ball) games.mouse.is_visible=False games.screen.event_grab=True games.screen.mainloop() main()

  • Handling multiple column data with Java

    - by Ender
    I am writing an application that reads in a large number of basic user details in the following format; once read in it then allows the user to search for a user's details using their email: NAME ROLE EMAIL --------------------------------------------------- Joe Bloggs Manager [email protected] John Smith Consultant [email protected] Alan Wright Tester [email protected] ... The problem I am suffering is that I need to store a large number of details of all people that have worked at the company. The file containing these details will be written on a yearly basis simply for reporting purposes, but the program will need to be able to access these details quickly. The way I aim to access these files is to have a program that asks the user for the name of the unique email of the member of staff and for the program to then return the name and the role from that line of the file. I've played around with text files, but am struggling with how I would handle multiple columns of data when it comes to searching this large file. What is the best format to store such data in? A text file? XML? The size doesn't bother me, but I'd like to be able to search it as quickly as possible. The file will need to contain a lot of entries, probably over the 10K mark over time.

  • ReSharper - Possible Null Assignment when using Microsoft.Contracts

    - by HVS
    Is there any way to indicate to ReSharper that a null reference won't occur because of Design-by-Contract Requires checking? For example, the following code will raise the warning (Possible 'null' assignment to entity marked with 'NotNull' attribute) in ReSharper on lines 7 and 8: private Dictionary<string, string> _Lookup = new Dictionary<string, string>(); public void Foo(string s) { Contract.Requires(!String.IsNullOrEmpty(s)); if (_Lookup.ContainsKey(s)) _Lookup.Remove(s); } What is really odd is that if you remove the Contract.Requires(...) line, the ReSharper message goes away. Update I found the solution through ExternalAnnotations which was also mentioned by Mike below. Here's an example of how to do it for a function in Microsoft.Contracts: Create a directory called Microsoft.Contracts under the ExternalAnnotations ReSharper directory. Next, Create a file called Microsoft.Contracts.xml and populate like so: <assembly name="Microsoft.Contracts"> <member name="M:System.Diagnostics.Contracts.Contract.Requires(System.Boolean)"> <attribute ctor="M:JetBrains.Annotations.AssertionMethodAttribute.#ctor"/> <parameter name="condition"> <attribute ctor="M:JetBrains.Annotations.AssertionConditionAttribute.#ctor(JetBrains.Annotations.AssertionConditionType)"> <argument>0</argument> </attribute> </parameter> </member> </assembly> Restart Visual Studio, and the message goes away!

My code is below: //Create the mail message MailMessage mail = new MailMessage(); //Set the addresses mail.From = new MailAddress("[email protected]", "My Name"); mail.To.Add(Email); //Set the subject and bodycontent mail.Subject = "Email Testing"; mail.Body = "This is the body of the email"; //Send the message using the SmtpClient SmtpClient smtp = new SmtpClient(); smtp.EnableSsl = true; smtp.Send(mail); My web.config has the following settings: <smtp from="[email protected]" deliveryMethod="Network"> <network host="smtp.gmail.com" password="password" port="587" userName="[email protected]" /> </smtp> During my troubleshooting I have tried: Using my personal gmail address as well as another from a domain hosted through Google Apps. Using ports 25, 465, and 587 Hard coding the config settings in the c# code instead of using the web.config Sending and telneting from multiple network locations to ensure the firewall/ISP was not blocking it Ensured that POP was enabled in the GMail settings (according to Google this should turn on the ability to send using SMTP) Changing the send from and replyTo address to ensure they match the account (apparently a GMail necessity). I am able to send and receive email fine through the GMail interface for both of my email accounts. I have also tried the settings and solutions offered in Question # 757987 to no avail. Any suggestions would be greatly appreciated. Thanks all.

  • Crazy idea: Connect .NET and SAP with SAP JCo using IKVM.NET

    - by Kottan
    Because the SAP Connector for .NET is no longer maintained by SAP, I am now looking for an alternative to connect the Microsoft world with the SAP world. I know there a third party products like ERPConnect, but I want to do this with tools from SAP. Therefore there arised the crazy idea to use the SAP Java Connector in combination with the tool IKVM.NET (www.ikvm.net/devguide/net2java.html). IKVM.NET provides The IKVMC tool, which converts Java bytecode to .NET dll's and exe's. "No sooner said than done!" I converted the SAP JCo to .NET dlls and created a new Visual Studio solution. I put all the JCO files into a subdirectory of my solution. I set 2 references to the generated IKVM.OpenJDK.Core.dll and sapjco.dll. Great, all JCO classes where now available as .NET classes. Full of optimism I wrote some little code to connect to a SAP system. JCO.Client client = null; client = JCO.createClient(...) The compiliation of my testcode had no errors. "Wonderful !" I thought. Then I started my tetstapplication. Unfortunately I got an exception calling JCO.createClient: Could not load middleware layer 'com.sap.mw.jco.rfc.MiddlewareRFC'\r\nno sapjcorfc in java.library.path I have 2 questions on this topic. 1) Do you think my idea using SAP Java Connector to connect .NET with SAP is a good idea or is it nonsens ? Perhaps someone had already the same idea ;-) 2) How can the above exception be solved ?

  • RadTabControl and MVVM

    - by Jeff
    First, so you know, Silverlight 4 and VS 2010 both RC and RIA services. I'm also new to Silverlight... I have a page that has a Telerik RadTabControl on it. It will always have six tabs, i.e. the number of tabs is not data driven. The tabs are used for various admin functions. One tab for managing users with a grid and edit view, another that will have basic company info - just a few text boxes on it. The other tabs are similar to these two. I'm trying to use MVVM and can't decide on the best approach. I don't think I want one big ViewModel that handles all six tabs - that would be big, ugly and harder to maintain. Any recommendations for approaches on how to break this out? Perhaps have a ViewModel for each tab? If so, how would I (generally) go about implementing something like that? Or is there another approach that makes more sense? Thanks, Jeff

  • error C2146: syntax error : missing ';' before identifier 'vertices'

    - by numerical25
    I would usually search for this error. But in VS C++ Express, this error comes up for just about every mistake you do. Any how I recieve this error below error C2146: syntax error : missing ';' before identifier 'vertices' everytime I add the following code at the top of my document // Create vertex buffer SimpleVertex vertices[] = { D3DXVECTOR3( 0.0f, 0.5f, 0.5f ), D3DXVECTOR3( 0.5f, -0.5f, 0.5f ), D3DXVECTOR3( -0.5f, -0.5f, 0.5f ), }; below is the code in it's entirety. Cant figure out whats wrong. thanks // include the basic windows header file #include "D3Dapp.h" class MyGame: public D3Dapp { public: bool Init3d(); }; MyGame game; // Create vertex buffer SimpleVertex vertices[] = { D3DXVECTOR3( 0.0f, 0.5f, 0.5f ), D3DXVECTOR3( 0.5f, -0.5f, 0.5f ), D3DXVECTOR3( -0.5f, -0.5f, 0.5f ), }; // the entry point for any Windows program int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow) { game.InitWindow(hInstance , nCmdShow); return game.Run(); } bool MyGame::Init3d() { D3Dapp::Init3d(); return true; }

  • Recommendations on developing a WPF application without using MVVM or similar

    - by Metro Smurf
    We were building out the next version of an in-house thick-client application using WPF/Prism (Composite Application Library). As we were nearly done with the client our team was put under new management and shortly thereafter: We were then directed to drop the Prism framework to keep things simple. This includes not using any type of Inversion of Control. We were directed to build out the WPF application without using MVVM or similar; and more along the lines of a traditional WinForm application. The idea is that if a developer sees a control in Visual Studio’s designer view, then (s)he should be able to click on the control and see exactly what it's doing without having to traverse through a view-model (or similar). We have now been tasked with building out the WPF application using one primary Window, use a Frame Control to contain the content, and use a Ribbon outside of the frame for the menu items. Reason we were provided to use Frame Control: a. We will show a view in the Frame with a Page (not a user control) and then load the page in the Frame. b. When a new view is to be shown in the Frame, the current view (Page) will be closed/disposed and the new view (Page) will take its place in the Frame. c. When a developer looks at the Page in design view, (s)he will be able to click on any control and see exactly what is being done. Given the restrictions of 1 and 2 above, we’d like to present another method of building out the application that: Can be presented as an alternative to using the “Frame Methodology” (item 3 above) but still provides the same type of functionality. Does not use MVVM (see #1 and #2 above). Provided the direction we’ve been given, any suggestions as to an alternative we can present? I’d request that the responses be kept on the professional level and thank you in advance.

  • Logging in worker threads spawned from a pylons application does not seem to work

    - by TimM
    I have a pylons application where, under certain cirumstances I want to spawn multiple worker threads to process items in a queue. Right now we aren't making use of a ThreadPool (would be ideal, but we'll add that in later). The main problem is that the worker threads logging does not get written to the log files. When I run the code outside of the pylons application the logging works fine. So I think its something to do with the pylons log handler but not sure what. Here is a basic example of the code (trimmed down): import logging log = logging.getLogger(__name__) import sys from Queue import Queue from threading import Thread, activeCount def run(input, worker, args = None, simulteneousWorkerLimit = None): queue = Queue() threads = [] if args is not None: if len(args) > 0: args = list(args) args = [worker, queue] + args args = tuple(args) else: args = (worker, queue) # start threads for i in range(4): t = Thread(target = __thread, args = args) t.daemon = True t.start() threads.append(t) # add ThreadTermSignal inputData = list(input) inputData.extend([ThreadTermSignal] * 4) # put in the queue for data in inputData: queue.put(data) # block until all contents are downloaded queue.join() log.critical("** A log line that appears fine **") del queue for thread in threads: del thread del threads class ThreadTermSignal(object): pass def __thread(worker, queue, *args): try: while True: data = queue.get() if data is ThreadTermSignal: sys.exit() try: log.critical("** I don't appear when run under pylons **") finally: queue.task_done() except SystemExit: queue.task_done() pass Take note, that the log lin within the RUN method will show up in the log files, but the log line within the worker method (which is run in a spawned thread), does not appear. Any help would be appreciated. Thanks ** EDIT: I should mention that I tried passing in the "log" variable to the worker thread as well as redefining a new "log" variable within the thread and neither worked. ** EDIT: Adding the configuration used for the pylons application (which comes out of the INI file). So the snippet below is from the INI file. [loggers] keys = root [handlers] keys = wsgierrors [formatters] keys = generic [logger_root] level = WARNING handlers = wsgierrors [handler_console] class = StreamHandler args = (sys.stderr,) level = WARNING formatter = generic [handler_wsgierrors] class = pylons.log.WSGIErrorsHandler args = () level = WARNING format = generic
