• Visual C# Returning an array

  I still need help understanding what is happening here: class ParamArrayWithReturn { public static void Main() { F(3, 2, 15); } public static int[][] F(int n, int m, int value) { int[][] x = new int[ n ][]; for (int i = 0; i < n; i++) { x[ i ] = new int[m]; for (int j = 0; j < m; j++) x[ i ][j] = value; } return x; } } I see that we are going to dimension array to 3 indexes. Then I see what happens after that is that we then create two internal array indexes inside those 3. I also see that in this case, we will end up having the value of 15 at each index. I believe it will look something like this: 15, 15 15,15 15, 15 Now why would we return x here And what happens to it when it returns to the method call I am confused by that part ...Show All

I agree on what has been said in this thread that both contests are to some extent unrelated, so you can enter both and potentially be eligible to win both, but only once per contest (that is, only one of your games could win per contest , regardless the number of you ...Show All

• SQL Server Replicate column to subscriber - even it if is unchanged in UPDATE statement

  Set publisher database table column to 1. Replicate table to subscriber (column is also 1 on subscriber once it is replicated). Set subscriber database column to 2. Update publisher database column to 1 (even though it is already 1). Change is NOT replicated to subscriber (it stays at 2). This means that replication is comparing the insert statement to its current value in the database. Is there any way to change this behavior We want the the column to replicate to the subscriber.

• Game Technologies: DirectX, XNA, XACT, etc. Extracting the transformation matrix for a subobject in a mesh

  I have an x-file containing some objects objects. I would like to load this as a mesh and then extract the transformation matrix for some of these subobjects. If I have designed a model (in 3ds max) with a box located at 0,0,0 and another located at 1,2,3 and neither one is rotated or scaled, then the xfile consists of the two boxes and each has a transformation matrix. The first has the identity matrix as its transformation and the second one has a translation to 1,2,3 as its matrix. How can I extract those two matrices without writing code to parse the xfile I need this to build a mechanical model onto which I plcae a number of connector pads. Later I want to design other objects and mount them on those connectors. For example i ...Show All

• Windows Forms Custom Control Settings Persistence

  Would someone have a simple example for me: I want to add user persistence for a user control. It's a trackbar with a text box below and a Caption above. A contextmenu brings up a propertygrid and lets the user change e.g. Maximum, Minimum, Caption Text etc. Of course he wants his changes persisted and I would like to place that functionality in the control so I don't have to worry about it any more. The IPersistComponentSettings stuff is a bit intimidating, so I would appreciate some example or some tutorial help... Thnx !

• Audio and Video Development Extending Classes in HDi - not working in Emulator

  We're seeing some weird behavior on the Toshiba Emulator. Object oriented javascript runs well in HDi - you can have multiple extensions of a class and they act as expected. However when this script was run in the Emulator all extended classes act like the very last class loaded. So for example if a Food class is extended to veggie, fruit and grain; in they Emulator they all act like the grain class (assuming it was the last one loaded). Am I missing something in the ECMA spec that prohibits object oriented javascript Hey Will, Here is what the spec says ECMAScript supports prototype-based inheritance. Every constructor has an associated prototype, and every object created by that constructor has an implicit referenc ...Show All

• Visual Studio Express Editions Basic Game and Interface, How to

  Hi there, im new to Visual basic 2005 and im trying to create a simple game using snippits of video and a computer interface to run the game, the only snag is i have no idea where to start. The idea is one video is shown and upon an input on the interface is activated, another video is played. Thats the basis of it. If any one has any info that may help or have any idea if its possible, it would be extremly useful. Thanks. I would think that the wondows media player object would be the place to start.

• Windows Forms CheckBoxList does not contain a public definition of 'GetEnumerator' error

  Hi, I have a CheckboxList on a web form. I want to cycle through the checkboxes in the list to determine which boxes have been checked. Seems easy enough..but I'm getting an error that the "CheckBoxList does not contain a public definition of 'GetEnumerator'". Here's my code: foreach ( CheckBox cb in cbSRlist) { // get Sales Region the user has access privs for if (cb.Checked){ Response.Write(cb.Text + "<BR>" ); } } ...the error is actually caused by the foreach statement which can't operate on the checkboxlist because it doesn't have a public def of 'getEnumerator. The same error occurs if I replace 'CheckBox' with 'ListItem' in the above foreach stmt. what am I missing th ...Show All

• Visual Studio Function evaluation disabled because a previous function evaluation timed out. You must continue execution

  This error happens when you sit at a check-point for around 30-40 seconds. Is there a way to disable this When I attempt to continue execution (to another break-point on the next line), it does not stop. Is this a Visual Studio setting or a runtime setting. Hi, What is happening is that break state was reached and something is being evaluated (e.g. property) in the Locals/Watch/etc window. Looks like this is timing out. You can disable property evaluation by default via the option Tools -> Options -> Debugging -> General -> Enable property evaluation and other implicit function calls. The side effect is that properties will not be evaluated by default. See blog entries like http://blogs. ...Show All
