It does the same thing as running Regasm.exe with the **/tlb** and **/codebase** options.  The **/codebase** option is probably the one you forgot.  **Regasm** likes assuming you put the DLL in the GAC and generates a warning when you don&#39;t.  The GAC is indeed a very good way to avoid DLL Hell, always a COM problem.  But not appropriate on your dev machine, you don&#39;t want to pollute the GAC while developing and testing the code.  It only matters on your user&#39;s machine, the one that&#39;s likely to be exposed to multiple versions.

Using the wrong version of Regasm.exe on a 64-bit machine is another way to get in trouble, there are usually 4 versions on your machine.  Be sure to distinguish the 32-bit and 64-bit versions (**c:\windows\microsoft\framework** vs **framework64**), they write different registry keys.  You want to pick the one that&#39;s compatible with the client app.  Using both is okay too, .NET code can run in either mode, but pretty unusual.  And distinguish between the v2.0.50727 (.NET 2.0 through 3.5SP1) and the v4.0 versions.  Picking the right Visual Studio Command Prompt is half the battle.

I have a date string, say &#39;`2008-09-11`&#39;. I want to get a timestamp out of this, but I need to specify a timezone dynamically (rather then PHP default). 

So to recap, I have two strings:

    $dateStr = &#39;2008-09-11&#39;;
    $timezone = &#39;Americas/New_York&#39;;

How do I get the timestamp for this?

EDIT: The time of day will be the midnight of that day.... $dateStr = &#39;2008-09-11 00:00:00&#39;;

PHP - strtotime, specify timezone

In Java to implement multiple inheritance we use interfaces. Is it the only use of interfaces? If yes, what is the main use of interface in Java? Why do we need interfaces in Java?

What exactly does the VS project option &quot;Register for COM interop&quot; actually do?  Because when I build my library with this option enabled I can call CreateObject on my library from VBScript.  But if I build without this and then run regasm manually CreateObject fails.  So I&#39;m wondering -- what does VS2010 do that I&#39;m not doing?

I&#39;ve been upgrading some Silverlight 3 apps to Silverlight 4 in Visual Studio 2010. My Silverlight 3 apps open fine in Visual Studio, but SL4 apps don&#39;t, with the following error:

`C:\Path\To\MyProject.csproj : error  : Unable to read the project file &#39;XNTVOD.AdminClient.csproj&#39;. 
C:\Path\To\MyProject.csproj(593,3): The imported project &quot;C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0\Microsoft.Silverlight.CSharp.targets&quot; was not found. Confirm that the path in the &lt;Import&gt; declaration is correct, and that the file exists on disk.
`

I had a problem with older VS Silverlight components and recently uninstalled most of the SL components, and right now in Add/Remove programs I have:

 1. Microsoft Silverlight
 2. Microsoft Silverlight 3 SDK
 3. Microsoft Silverlight 4 Toolkit April 2010

The `&lt;import&gt;` declaration looks like this for the SL4 project:

`&lt;Import Project=&quot;$(MSBuildExtensionsPath32)\Microsoft\Silverlight\$(SilverlightVersion)\Microsoft.Silverlight.CSharp.targets&quot; /&gt;`

That folder, `C:\Program Files (x86)\MSBuild\Microsoft\Silverlight\v4.0` only has two files in it:

`Microsoft.Ria.Client.targets`

`Microsoft.Ria.Client.VisualStudio.targets`

What Silverlight development component am I missing in particular? I see a bunch of different options, from Silverlight 4 SDK Beta to VS Tools for Silverlight 4 and a bunch of others. I don&#39;t want to install stuff that will get me right back to the situation I had before this one with outdated components.

Below is a list of the SQL components that I installed in the Visual Studio 2010 Professional setup. Sadly, while trying to work I could not find [SQL Server Management Studio][1] 2008. 

Is there a way to download SQL Server Management Studio 2008 separately and install only that component?

Since in the past I installed SQL Server Management Studio 2005 with a whole new instance of [SQL&amp;nbsp;Server 2005][2] and had couple of instances, and it was a bit messy.

The problem is, that I want to group partial class files in a way in the Solution Explorer, that visual Studio displays a [+] in front of the filename which I than can expand to see all other dependant files.

But my classes are shown in two rows below each other:

    &gt; CustomerServiceDao.cs
    &gt; CustomerServiceDao.Query.cs

The result I want to have is something like that.

    + CustomerServiceDao.cs
        &gt; CustomerServiceDao.Query.cs

Is there any naming convention which I have to follow in order to show the partial files grouped?


### EDIT
It works. That&#39;s great. But are there any naming conventions? e.g. ascx does it by default ...

What is the real difference between these two options? What I know is:

**Register for COM Interop**  
This options executes regasm on the assembly and registers the assembly as an COM component(or maybe not) in the registry with all COM like registry entries.
Does this step generates a TLB file? What else is done?

Sometimes I see a tlb is generated when I compile the project but sometimes not, why is this? 

**Make assembly COM visible**  
What effect does this one has on an assembly? If I have the following type inside this assembly, do I still need to specify the &quot;Make assembly COM Visible&quot; even though my type is marked as ComVisible?

    [GuidAttribute(&quot;02810C22-3FF2-4fc2-A7FD-5E103446DEB0&quot;), ComVisible(true)]
    public interface IMyInterface
    {

I am trying to build a small application in C# which should start/stop an IIS Express worker process. For this purpose I want to use the official &quot;IIS Express API&quot; which is documented on MSDN: http://msdn.microsoft.com/en-us/library/gg418415.aspx

As far as I understand, the API is based (only) on COM interfaces. To use this COM interfaces I&#39;ve added a reference to the COM library in VS2010 via Add Reference -&gt; COM -&gt; &quot;IIS Installed Versions Manager Interface&quot;:

![][1]


So far so good, but what&#39;s next? There is an `IIISExprProcessUtility` interface available which includes the the two &quot;methods&quot; to start/stop an IIS process. Do I have to write a class which implements this interface?

    public class test : IISVersionManagerLibrary.IIISExprProcessUtility
    {
        public string ConstructCommandLine(string bstrSite, string bstrApplication, string bstrApplicationPool, string bstrConfigPath)
        {
            throw new NotImplementedException();
        }

        public uint GetRunningProcessForSite(string bstrSite, string bstrApplication, string bstrApplicationPool, string bstrConfigPath)
        {
            throw new NotImplementedException();
        }

        public void StopProcess(uint dwPid)
        {
            throw new NotImplementedException();
        }
    } 

As you can see, I&#39;m not a professional developer. Can someone point me in the right direction.
Any help is greatly appreciated.

**Update 1:**
According to the suggestions I&#39;ve tried the following code which unfortunately doesn&#39;t work:

![alt text][2]
Ok, it can be instantiated but I cannot see how to use this object...

How do I make a C# DLL into a COM interop DLL that can be consumed by a VB6 application?


Turn a simple C# DLL into a COM interop component

I have created two .NET Interop assemblies from two different third-party COM DLLs. Both of the COM DLLs contained a type named `COMMONTYPE`. Therefore, `COMMONTYPE` is now exposed through the two Interop assemblies as well.

I have a third project that needs to use these two Interop assemblies, and I get the infamous compile time error:

&gt;The type `&lt;ABC&gt;` exists in both `&lt;ASSEMBLY1.dll&gt;` and `&lt;ASSEMBLY2.dll&gt;`

Since the COM DLLs are provided by a third-party vendor, I have no access to the source code, and I&#39;m writing a C# Console application, which means I have no web.config file where I could add the `debug=false` workaround. What can I do?
