  • Is it possible to create a Mono bundle that includes WPF libraries?

    - by Thiado de Arruda
    I know WPF libraries aren´t implemented by mono class library, however(as far as I know) the mono 2.6 runtime is fully compatible with the .NET 2.0/3.5 runtime, so if the WPF libraries only make PInvoke calls to windows api it is theoretically possible to run a wpf application on windows using the mono runtime. The reason for wanting that is deploying a wpf application as a standalone executable for windows. Has anyone tried something like that before? If so, what were the results?

  • How to loop through the ChartColorPalette properties and add to list?

    - by John M
    I am using the Microsoft Chart Controls for .NET 3.5 (C#) and have a chart in a winform. My hope is to allow the user to change the color palette based on their preference. How do I iterate through the color properties of the ChartColorPalette and add them to a combobox list? I know it should be something like: for each(something in ChartColorPalette) { combobox.items.add(something.ToString); }

  • How to connect to local database via website?

    - by Carlo
    Hi I have a website used by clients for reporting purposes and would like to give clients the option of my website reading their local database directly (instead of them providing data in a file format). In most instances their database would be SQL Express setup on their localhost. How can I connect to a clients local SQL server via my website, using asp.net / javascript etc? If the client provides their connection string properties, localhost would just refer to my server's localhost... Thanks

  • Can I use WCF to replace my current Web Service and Window Service combination?

    - by gun_shy
    I need a little bit of advise regarding the situation I am faced with. The current arrangement I have been tasked with improving just doesn't sit well with me and I feel like there is a better way to do it. The more I read about WCF, the more I get the feeling that it might be what I am looking for. Right now, I have an asp.net client, a .net web service, a windows service, a ms sql database, and a third party application that is used for processing a group of 'project' files into a finalized file. Since the third party application can only handle processing one 'project' at a time, the combination of the web service, window service, and database have been arranged to create a job queue manager for the third party application. The client sends a zip 'project' file containing multiple sub files to the web service. The web service adds a new 'project' line to the database, generating a unique job id. The zip file is expanded to a folder location on the server using the job id as the folder name. The web service then returns the job id to the client. The client will use this id to poll the web service for the status of the job submitted. When the job is complete, the client will request the processed file. The windows service polls the database every x minutes. If a new job exists, the service will pull the oldest job and send it to the third party app for processing. If the processing succeeds, the window service updates the project line in the database, marking the job complete. The window service will continue to process any non complete jobs in the database until there are no more. When it stops finding any jobs, it will sleep x minutes and then poll the database again. I do not like the fact that the window service has to poll the database. If there is only one job submitted, the client will have to wait for the window service to poll and then wait while the 'project' is being processed. It seems like WCF could be used to combine the web and window services using a combination of the InstanceContextMode.Single and ConcurrencyMode.Multiple. So far, I have been unable to find any articles or examples that would point me in the right direction. Can WCF be utilized to accomplish the job queue logic of the current arrangement in a better way? As always, any help is more than appreciated.

  • Detect non-closed connections to SQL

    - by JoeJoe
    I've inherited a very large project in ASP.net, SQL 2005 and have found where some SQL connections are not closed - which is bad. Without going thru every line of code, is there a way to detect if connections are not being closed? Performance counter? as a follow up - how does SQL reclaim unclosed connections. I'm using non-pooled connectionstring.

  • Neat way of calling InvokeRequired and Invoke

    - by ho
    I seem to remember seeing some neat way of calling InvokeRequired and Invoke to avoid repeating too much code in every event handler but I can't remember what that was. So does anyone know a neat way of writing that code? Preferably for VB.Net 2005.

  • What is the correct way to create a single instance application?

    - by Nidonocu
    Using C# and WPF under .net (rather than WindowsForms or console), what is the correct way to create an application that can only be run as a single instance? I know it has something to do with some mythical thing called a mutex, rarely can I find someone that bothers to stop and explain what one of these are. The code needs to also inform the already running instance that the user tried to start a second one, and maybe also pass any command line arguments if any existed.

  • Object relationships

    - by Hammerstein
    This stems from a recent couple of posts I've made on events and memory management in general. I'm making a new question as I don't think the software I'm using has anything to do with the overall problem and I'm trying to understand a little more about how to properly manage things. This is ASP.NET. I've been trying to understand the needs for Dispose/Finalize over the past few days and believe that I've got to a stage where I'm pretty happy with when I should/shouldn't implement the Dispose/Finalize. 'If I have members that implement IDisposable, put explicit calls to their dispose in my dispose method' seems to be my understanding. So, now I'm thinking maybe my understanding of object lifetimes and what holds on to what is just wrong! Rather than come up with some sample code that I think will illustrate my point, I'm going to describe as best I can actual code and see if someone can talk me through it. So, I have a repository class, in it I have a DataContext that I create when the repository is created. I implement IDisposable, and when my calling object is done, I call Dispose on my repository and explicitly call DataContext.Dispose( ). Now, one of the methods of this class creates and returns a list of objects that's handed back to my front end. Front End - Controller - Repository - Controller - Front End. (Using Redgate Memory Profiler, I take a snapshot of my software when the page is first loaded). My front end creates a controller object on page load and then makes a request to the repository sending back a list of items. When the page is finished loading, I call Dispose on the controller which in turn calls dispose on the context. In my mind, that should mean that my connection is closed and that I have no instances of my controller class. If I then refresh the page, it jumps to two 'Live' instances of the controller class. If I look at the object retention graph, the objects I created in my call to the list are being held onto ultimately by what looks like Linq. The controller/repository aside, if I create a list of objects somewhere, or I create an object and return it somewhere, am I safe to just assume that .NET will eventually come and clean things up for me or is there a best practice? The 'Live' instances suggest to me that these are still in memory and active objects, the fact that RMP apparently forces GC doesn't mean anything?

  • Creating Tests at Runtime

    - by James Thigpen
    Are there any .NET testing frameworks which allow dynamic creation of tests without having to deal with a hokey Attribute syntax? Something like: foreach (var t in tests) { TestFx.Run(t.Name, t.TestDelegate); } But with the test reporting as you would expect... I could do something like this with RowTests et al, but that seems hokey.
