  • 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.

  • 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.

  • Creating a 64bit build in Visual studio

    - 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.

  • 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!

  • 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.

  • Objective C BitConverter Equivalent

    - by user352891
    Hi there, I'm wondering if there is an Objective C equivalent to .Net's BitConverter.GetBytes() method. For example, in C#, I can write something like this: byte[] lengthPrefix = BitConverter.GetBytes(message.length); What would the equivalent be in Objective C? Some example code would be greatly appreciated. Thanks in advance.

  • why does vb not support multiple inheritance?

    - by isolatedIterator
    I've seen some discussion on why c# does not implement multiple inheritance but very little as to why it isn't supported in vb. I understand that both c# and vb are compiled down to intermediary language and so they both need to share similar restrictions. The lack of multiple inheritance in VB seems to have been given as one reason for the lack of the feature in dot net. Does anyone know why VB doesn't support multiple inheritance? I'm hoping for a bit of history lesson and discussion on why this was never considered for VB.

  • How to insert a DataTable with existing Key to a SQL Server Table.

    - by user296575
    I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields: QuestionNumber (unique integer key) QuestionText QuestionType In my SQL Server database I created a Table called "QUESTION" with the same fields. QuestionNumber is defined as integer unique key, auto increment Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1). How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

  • Deploying XBAP as an ActiveX

    - by Kaveh Shahbazian
    How can I deploy a XBAP to a client machine as an ActiveX (Which I can instantiate and use from JavaScript, passing parameters to it, getting parameters from it, etc)? This is part of an ASP.NET site, and will be in full trusted mode (I have solved that part, actually I have implemented a test XBAP that can edit a text file on local hard drive of a client machine). Thanks
