  I am writing a program that generates excel reports, currently using the Microsoft.Interop.Excel reference. My dev computer has Excel on it, but the end user may or may not have Office installed. Will this tool fail if Office isn't installed on the end users computer, or is this interop service separate from the actual application?

• Dependency issue with MSBuild 4.0 when doing DllImport from C# into unmanaged C++ library

  - by GregC

  Explicitly setting dependency in VS2010 between unmanaged C++ project and C# project is honored in VS2010, but dependency is ignored in MSBuild 4.0. It is impossible to add a reference to unmanaged C++ project from C# project, afaik. How do i ensure correct build order if a solution contains unmanaged and managed projects?

• With Protobuf-net, does it allow deserialization reuse existing instances if they are the same?

  - by Stecy

  I'm using Protobuf-net. Suppose I have a list of Gizmo objects serialized and that each gizmo object reference a Gazoo object. The Gazoo object might be the same object referred by several Gizmo objects. How would deserialization work in this situation? Would I get more than one copies of Gazoos for the same referred one in the gizmo objects? What I would expect would be one copy of Gazoo for all the duplicates in the serialized data.

• cocoa -- What is the proper way to tell an NSWindow to redisplay its contents?

  - by William Jockusch

  According to the NSWindow Class Reference, you should "rarely need to invoke" the NSWindow methods "display" or "setViewsNeedDisplay". So what is the usual way to redisplay the window's contents? EDIT: I am having trouble dealing with resizing events. I just want to have everything scale proportionally. See this question. As no one seems to have any ideas for using masks to get it to happen, I want to redraw the whole thing.

• binding a usercontrol to the opposite of a bool property

  - by SnOrfus

  Pretty straightforward: I'm looking to do the same as this but in winforms. Everything that google seems to pull up is wpf specific (ie. I don't want to reference presentationframework.dll) Explained if you don't want to read the link: The following is a representation of the intent of what I'd like to do, though it obviously doesn't work. CheckBox1.DataBindings.Add(new Binding("Checked", this.object, "!SomeBool"));

  Is there any plug-in that provides an integrated shell (i.e. command prompt) in Eclipse? The console only seems to be for interaction with a running program. I've found a reference to the plug-in Open extern but that opens an external command window, and I'd rather have it integrated with Eclipse.

  I have a class that uses a lot of database internally, so I built the constructor with a $db handle that I am supposed to pass to it. I am just getting started with PHPUnit, and I am not sure how I should go ahead and pass the database handle through setup. public function setUp(/*do I pass a database handle through here, using a reference? aka &$db*/){ $this->_acl = new acl; } public function __construct(Zend_Db_Adapter_Abstract $db, $config = array()){

  C# spec. allows you to call a function void foo(params int[] x) with zero parameters. However, I didn't find in C# Lang.

• When is the Data Vault model the right model for a data-warehouse?

  - by Stephan Eggermont

  I recently found a reference to 'Data Vault modeling' as a model for data-warehouses. The models I've seen before are Inmon and Kimball. The author refers to possible performance problems due to the joins needed. It looks like a nice model, but I wonder about the gotcha's. Are there any experience reports on-line?

• How is "Make Object ID" implemented in the .NET debugger?

  - by Omer Raviv

  Hi, I would like know how this feature is implemented in VS - I understand it holds some sort of weak-reference to the object in the debugged-application's memory, but how exactly is it accomplished? I know simply tracking the address (as in native code) wouldn't work, because the GC might move the object about, invalidating the address. Thanks.
