  • COM Interop between 32 bit and 64 bit applications

    - by rip
    I have a .NET windows forms application compiled as x84 – it needs to be compiled as x84 because it references 3rd party DLLs which are 32 bit. The application uses COM interop to automate Office applications and also AutoCAD. My question is: will my COM interop code work okay on a 64 bit operating system against the 64 bit versions of Office and AutoCAD? I’m going to try this out but I wondered whether someone knew of any problems?

  • Render a view as a string

    - by Dan Atkinson
    Hi all! I'm wanting to output two different views (one as a string that will be sent as an email), and the other the page displayed to a user. Is this possible in ASP.NET MVC beta? I've tried multiple examples: RenderPartial to String in ASP.NET MVC Beta If I use this example, I receive the "Cannot redirect after HTTP headers have been sent.". MVC Framework: Capturing the output of a view If I use this, I seem to be unable to do a redirectToAction, as it tries to render a view that may not exist. If I do return the view, it is completely messed up and doesn't look right at all. Does anyone have any ideas/solutions to these issues i have, or have any suggestions for better ones? Many thanks! Below is an example. What I'm trying to do is create the GetViewForEmail method: public ActionResult OrderResult(string ref) { //Get the order Order order = OrderService.GetOrder(ref); //The email helper would do the meat and veg by getting the view as a string //Pass the control name (OrderResultEmail) and the model (order) string emailView = GetViewForEmail("OrderResultEmail", order); //Email the order out EmailHelper(order, emailView); return View("OrderResult", order); } Accepted answer from Tim Scott (changed and formatted a little by me): public virtual string RenderViewToString( ControllerContext controllerContext, string viewPath, string masterPath, ViewDataDictionary viewData, TempDataDictionary tempData) { Stream filter = null; ViewPage viewPage = new ViewPage(); //Right, create our view viewPage.ViewContext = new ViewContext(controllerContext, new WebFormView(viewPath, masterPath), viewData, tempData); //Get the response context, flush it and get the response filter. var response = viewPage.ViewContext.HttpContext.Response; response.Flush(); var oldFilter = response.Filter; try { //Put a new filter into the response filter = new MemoryStream(); response.Filter = filter; //Now render the view into the memorystream and flush the response viewPage.ViewContext.View.Render(viewPage.ViewContext, viewPage.ViewContext.HttpContext.Response.Output); response.Flush(); //Now read the rendered view. filter.Position = 0; var reader = new StreamReader(filter, response.ContentEncoding); return reader.ReadToEnd(); } finally { //Clean up. if (filter != null) { filter.Dispose(); } //Now replace the response filter response.Filter = oldFilter; } } Example usage Assuming a call from the controller to get the order confirmation email, passing the Site.Master location. string myString = RenderViewToString(this.ControllerContext, "~/Views/Order/OrderResultEmail.aspx", "~/Views/Shared/Site.Master", this.ViewData, this.TempData);

  • Offline backup synchronization

    - by Pavan Kumar
    There is a Central Server running Windows Server 2003 and SQL Server 2005 and there are 7 client machines situated in various places and has XP Pro & SQL Server 2005 installed in all of them. They are not interconnected so they are physically seperate. One person goes to each of these centers maybe twice a month and takes the backup (Full database consisting of mdf and ldf files) with a pen drive and brings it to the Central server which contains the central database holding same schema as all the other client databases. I need to synchronize each backup database (belonging to different centers) one by one to update the existing data or inserting new data in the central database . The solution i got was Replication. The pendrive is brought to central server consisting of 7 instances of the databases and then the databases is attached to the central server one by one to the same SQL Server where the central database exists. Then my idea was to replicate the backup database one by one i.e using single subscription (Central Database) and multiple publication ( i.e 7 instances of databases in my case) toplogy by performing replication locally (i.e in the same machine). So i tried to develop a UI in C# .Net to programatically run the Transactional Replication with push subscription using RMO Programming (which is incomplete as of now because there is no point in developing when you already know it is not the solution). Transactional Replication can either be set to initialize with a snapshot or without a snapshot. If i go for the first option i.e with a snapshot , the data whatever is present in Central Database is overwritten by the new data . So the data present initially in the central database is lost. If i try to initialize without snapshot , no data (the data already has the updated and new data) will be sent from the backup database to server. The replication will work in a scenario where any incremental changes is done only after you set the replication . So the initial data whatever was present in the backup database when setting up the replication will not be replicated when running the snapshot agent for the first time to synchronize. Only changes in the backup database thereafter will be reflected to the central database .(Remember I am not going to insert new data or make any changes to the backup database after i attach it to the Central Server. ) So this solution is not feasible. I want a solution for synchronizing from one client database to central database present in the same machine using C#.NET. If you can provide me small example maybe with two databases(with same schema) DB1(Client) to DB2(Server) consisting of one or two tables it will be very helpful. The synchronization is not bidirectional.I want to only update existing data or insert new data from DB1 to DB2 (DB2 may contain some data initially). Thanks and Regards Pavan

    You wrote at: Opened SerialPort crashes C# application "A look into the .NET Framework source code helped a lot. But I think the thrown ObjectDisposedException should be caught by the SerialPort, not by the user." I'd like to take a look on source code for serialPort. How can I do it?

  • Htaccess rewrite rule .aspx to .php

    - by Markus Ossi
    Background: I have a website that has been built with ASP.NET 2.0 and is on Windows hosting. I now have to rewrite my site in PHP and move it into Linux hosting. I have a lot of incoming links to my site from around the web that point directly into the old .aspx-pages. The site itself is very simple, one dynamic page and five static ones. I saved the static .aspx pages as .php-pages and rewrote the dynamic page in PHP. The dynamic page is called City.aspx and I have written it in PHP and it is now called City.php. On my old Windows hosting, I used ASP.NET's URL mapping for friendly URL. For example, incoming URL request for Laajakaista/Ypaja.aspx was mapped into City.aspx?CityID=981. My goal: To redirect all human visitors and search engines looking for the old .aspx pages into the new .php pages. I am thinking that the easiest way to redirect visitors into new pages will be by making a redirect, where all requests for .aspx-files will be redirected into .php filetypes. So, if someone asks for MYSITE/City.aspx?CityID=5, they will be taken into MYSITE/City.php?CityID=5 instead. However, I am having a lot of trouble getting this to work. So far this is what I have found: rewriterule ^([.]+)\.aspx$ http://www.example.com/$1.php [R=301,L] However, I think this can not handle the parameters after the filetype and I am also not quite sure what to put on front. To make things a bit more complicated, at my previous site I used friendly URL's so that I had a huge mapping file with mappings like this: <add url="~/Laajakaista/Ypaja.aspx" mappedUrl="~/City.aspx?CityID=981" /> <add url="~/Laajakaista/Aetsa.aspx" mappedUrl="~/City.aspx?CityID=988" /> <add url="~/Laajakaista/Ahtari.aspx" mappedUrl="~/City.aspx?CityID=989" /> <add url="~/Laajakaista/Aanekoski.aspx" mappedUrl="~/City.aspx?CityID=992" /> I tried to make a simple redirect like this: Redirect 301 Laajakaista/Aanekoski.aspx City.php?CityID=992 but was not able to get it to work. I ended up with an internal server error and a 50k .htaccess-file... Any help is greatly appreciated.

    - by user48408
    I have an old .net 2.0 windows app I need to deploy on a windows 7 machine and its not going too well. I want to build a native 64 bit version rather than a 32bit capable of running on a 64bit environment. I'm working with Visual studio 2005 My question is what settings do I need to set within each project of my solution, (both the windows app + my dll's that it references) and what settings i should set on my install project (I have a deployment project for distribution)

  • What are guard methods/classes?

    - by Paul Sasik
    i just noticed the guard method/class mentioned in this question and i don't really get the concept from the answers. And alas, Jon Skeet's link to an MS site never loaded. A few quick Google searches seemed to yield only products, not software engineering concepts. Any explanation and/or samples would be appreciated. (Especially from the .Net side of things.)

  • Speed up login to StarTeam?

    - by Slapout
    I'm working on a program that accesses StarTeam using the StarTeam SDK for .NET. And I've noticed that it takes about 10 seconds to login to the StarTeam server. I'm wondering if there's anything I can do to speed that up. Edit I used this command to run the StarTeam Cross Platform client with debugging output: stjava.exe StarTeamCP.stjava -- -netmon It appears that the delay happens when it send the command SRVR_CMD_GET_USER_PERSONAL_INFO. So I don't think there's anything I can do to speed it up.

  • Custom MembershipProvider attempts to pass empty creds after IIS restart

    - by Joseph DeCarlo
    I have a C# custom ASP.Net MembershipProvider. When the user attempts to navigate to another part of the site after IIS is restarted, it doesn't navigate to the login page to collect credentials, but instead attempts to authenticate with empty credentials. Can anyone tell me what I have to do to identify that the new authentication needs to take place and that new creds need to be gathered? I have a complementary custom IHttpModule implementation that allows me to intercept events like BeginRequest and AuthenticateRequest, if that helps.

  • Image control with pan and zoom ability

    - by corvus
    I am looking for a free .net winforms control which is able to display images. PictureBox isn't a solution because you have to implement all pan&zoom events yourself. The control should be able to display images like 4000x5000 pixels, have zoom and pan buttons.

  • Controllers and threads

    - by user72185
    Hi, I'm seeing this code in a project and I wonder if it is safe to do: (ASP.NET MVC 2.0) class MyController { void ActionResult SomeAction() { System.Threading.Thread newThread = new System.Threading.Thread(AsyncFunc); newThread.Start(); } void AsyncFunc() { string someString = HttpContext.Request.UrlReferrer.Authority + Url.Action("Index", new { controller = "AnotherAction" } ); } } Is the controller reused, possibly changing the content of HttpContext.Request and Url, or is this fine (except for not using the thread pool). Thanks for info!
