• Which accessType should I use when calling InternetOpen?

  - by Colen

  According to the MSDN, you can specify an access type parameter to InternetOpen. Two of the options for the dwAccessType parameter are: INTERNET_OPEN_TYPE_DIRECT - Resolves all host names locally. INTERNET_OPEN_TYPE_PRECONFIG - Retrieves the proxy or direct configuration from the registry. Which of these should I use? I don't know which would be "better". We don't want our application to do anything clever, all we want it to do is access the internet in a normal way.

  - by Lenik

  Our solution is built using Release|x86; however, when our designers try to build using Blend they are forced to use Any CPU which we don't want to to add since it's going to change the behavior. I checked version 4, and it does not seem to address this issue. Is there a way to specify Solution Configuration/Platform when using Blend? Any workarounds?

• Absolute UriSource of a Resource image

  - by Louis Rhys

  I have a WPF project. If I store image in {ProjectRoot}\Images\image.png, and compile it as Resource then I can access it from a xaml (this xaml is located at Root) as BitmapImage by BitmapImage UriSource="Images/image.png". But if I move the xaml to another folder, say {ProjectRoot}\Xamls, now I have to use BitmapImage UriSource="../Images/image.png". Is there a way to specify an absolute project path, so that I can refer to them with the same path regardless of the location of the xaml?

  - by CSharperWithJava

  I'm inserting new rows into a SQLite table, but I don't want to insert duplicate rows. I also don't want to specify every column in the database if possible. I don't even know if this is possible.

• Odd behaviour with scala method syntax

  - by Ceilingfish

  Hi chaps, I hit a bit of a quirk of scala's syntax I don't really understand object Board { def getObjectAt(x:Int, y:Int):Placeable = return locations(x)(y) } works fine. But object Board { def getObjectAt(x:Int, y:Int):Placeable { return locations(x)(y) } } returns the error Board.scala:8: error: illegal start of declaration return locations(x)(y) I found some stuff that says the second form convinces the scala compiler you're trying to specify an expansion to the return type Placeable. Is there a way I can fix this, or should I just avoid specifying a return type here?

• What's the Microsoft Ajax equivalent to jquery.ajaxSetup() or .ajaxError()?

  - by Seth Petry-Johnson

  I have an ASP.NET MVC site that uses both Microsoft Ajax [Ajax.BeginForm()] and jQuery to make asynchronous requests.

In jQuery I can accomplish this with either .ajaxSetup() or .ajaxError(). What is the equivalent in the Microsoft Ajax client library? I'm fairly sure it's something in the Sys object but I can't find it...
