How could I find the size of a picture (http://www.willapa.wednet.edu/images/amigo.jpg)
When every I try to use .Legnth, it tells my Stream dosn't support seeking... or somthing like that.
Any ideas?
Oh, yeah...
and also, I was wondering if it was possible to do a .GetFiles over the internet....

When using he HTTPWebRequest a header will be returned with some info including length and modified date.

Right, specifically HttpWebResponse.ContentLength and HttpWebResponse.LastModified.

How would I identify what type of webserver a site is running? (IIS, Apache, Xitami)
Right now, i'm messing around in the System.Net Namespace but not really finding anything.
Can anyone help me out?

Just make a HttpWebRequest and get the HttpWebResponse. The HttpWebResponse.Server property returns a string that identifies the server. This corresponds to the HTTP Server: header.
Here's an example:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.codeproject.com");
HttpWebResponse response = (HttpWebResponse)request.GetResponse();
Console.WriteLine(response.Server);

This - and most solutions I post - I know already. I'm both blessed and cursed with a photographic memory.   Besides, HTTP and HTML (if you call that programming) was one of the first programming things I did besides the dinky little things I did on my C64, so the HTTP Server: header was nothing new.
It's not that I always remember the exact method or property, though. In some cases, I know that a certain class has a certain method or property that takes certain parameters and returns a certain type. As I've said many times in the past, it isn't so much memorizing every signature in the .NET Framework (or anything else for that matter), as it is remember that something exists and roughly where to find it. The important part of research is at least becoming familiar with what's available and having an idea of where to look. So, using your question as an example (if I couldn't remember what the property or method was called), I knew it would be on the HttpWebResponse (since the whole pluggable protocol API is aptly and consistently named - the HttpWeb part - and that the client couldn't know what the server was till it got a response back - thus using Response instead of Request) so I would just jump to that class and look.

Hello,
What would be the best way to go about making a computer restart after my setup program has finished running?
I can't seem to find anything built-in to the setup program. Will I need to specify a custom action to do this?
Thanks,
Blake

If you're using Windows Installer, it decides if a reboot is necessary. If - for some odd reason - you need to reboot regardless of what Windows Installer thinks, create a REBOOT property in the Properties table and set it to Force. If you're using VS.NET's installer project, you'll have to download the Windows Installer SDK on the Platform SDK web site, install Orca (copied to your machine as Orca.msi in the PSDK's bin directory), open your compiled MSI, and add the property to the Properties table manually.
If you need to conditionally set it, you can use a CustomAction that sets the REBOOT property to Force. Note the case of the REBOOT property, though - it must be all uppercase.
You could also write a custom action DLL, but it isn't necessary since - as you can see - you can have Windows Installer do it.

Thanks for the info.
If I am using the bootstrapper sample form Microsoft's website to do a silent installation of .Net framework, will Windows Installer take the .net framework installation into account when determining if the reboot is necessary? And, I am using MDAC and Jet merge modules in the setup program also. Will it take these into account?
Thanks for the reply!
Blake

The bootstrapper runs before the Windows Installer package, so Windows Installer won't know. I'm not aware of how the bootstrapper could tell the installer to reboot, since the bootstrapper typically only knows about the Database object (where the properties are read-only). Perhaps the bootstrapper can get the Instance after invoking MSI on the package, but you'd have to read the Windows Installer SDK. I've never had to attempt modifying the installer from the boostrapper to know.
In most cases, though, you want the bootstrapper to reboot before restarting the Windows Installer package. If the .NET Framework installation isn't finalized when your MSI package begins, you may run into problems. While rare, I have had problems where - after installing SP2 - the GAC wasn't setup completely and trying to install assemblies into a GAC that didn't exists screwed some things up. It wasn't disasterous, but your average stupid user using your product might not like it.
As far as Jet and MDAC go (they are merge modules), if Windows Installer determines that files they needed to replace are in use or that the machine needs to reboot (which is stupid in most cases for NT-based Windows OSes because the user need only logout and back on), it will do so either when necessary or at the end, depending on what you set the REBOOT property to. Valid values are Force, Surpress, and ReallySurpress. See the Windows Installer SDK for more information.

Just one comment not on the technical side. If you don't wish to royally piss off most of your users, don't force a reboot at all, unless it is extremely neccesary. Several programs i've used lately have popped up a box at the end simply saying "Click OK to reboot". This is rarely neccesary, and certainly wasn't in some instances.
This is amazingly bad usability design, and is hugely presumptious. Try to avoid this! Just a comment

This is a moot point with Windows Installer. Setting REBOOT to Force still prompts the user with a Yes/No dialog. Your comment is most definitely valid in a custom installer, but that's not the case here.

Please give it some thought about forcing a clients machine to reboot. Just think how irritating it is when an application reboots your machine. Personaly believe the best option is to place messages in the installer to say a reboot is necessary, and leave it up to the end-user.
My one cent.

Has anyone used C# to do a mailmerge for word 2002?
I have a CSV file that is coma delimited that is created by a web page. Need to take that CSV file and have it do a mailmerge to a Word doc.

Any know what I'm doing wrong? I have this mailmerge and it does not seem to Close WINWORD.EXE.
I also tried using oWordDoc.Close(ref oFalse, ref missing, ref missing); line in the code and it will not close it either. Tried using both oWordApp.Application.Quit(ref oFalse, ref missing, ref missing); and oWordDoc.Close(ref oFalse, ref missing, ref missing); Then it seems to hang the web page. Any help would be nice.
object fileName = "c:\\temp\\letter.doc";
string SourceFile = "c:\\temp\\Names.csv";
object SourceFormat = Word.WdOpenFormat.wdOpenFormatText;
object oFalse = false;
object oTrue = true;
object missing = System.Reflection.Missing.Value;
object query = "SELECT * FROM `DirectMailList123200311834$`";
object SaveAsFileName = "c:\\temp\\MergedLetter.doc";
Word.Application oWordApp = new Word.Application();
Word.Document oWordDoc = oWordApp.Documents.Open(ref fileName, ref missing, ref oTrue, ref missing,ref missing,ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
oWordDoc.MailMerge.OpenDataSource(SourceFile, ref SourceFormat, ref missing, ref missing, ref oTrue, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing,ref query,ref missing,ref missing, ref missing);
oWordDoc.MailMerge.Destination = Word.WdMailMergeDestination.wdSendToNewDocument;
oWordDoc.MailMerge.Execute(ref oFalse);
oWordApp.ActiveDocument.SaveAs(ref SaveAsFileName, ref missing, ref missing, ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing,ref missing);
oWordApp.Application.Quit(ref oFalse, ref missing, ref missing);

Hi everybody
Does anyone know if there is a way to implement named pipes using C#?
Thank you very much!!

First, let me just say that .NET Remoting is the recommended way for inter-process communication - even over disparate networks like the Internet. See the System.Runtime.Remoting namespace for more information, or read the MS Press book, ".NET Remoting" (it's pretty good for both beginners and advanced developers alike).
Having said that, you have to P/Invoke the CreateNamedPipe function and create a SECURITY_ATTRIBUTES structure like so:
[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
public static extern IntPtr CreateNamedPipe(string name, int openMode, int pipeMode,
int maxInstances, int outBufferSize, int inBufferSize,
int defaultTimeout, ref SECURITY_ATTRIBUTES);
[StructLayout(LayoutLind.Sequential)]
public struct SECURITY_ATTRIBUTES
{
public int length;
public IntPtr securityDescriptor;
public bool inheritHandle;
}If you don't want to worry about the SECURITY_ATTRIBUTES struct in the CreateNamedPipe method, you could probably change the param to a generic object and pass null when calling the method. See the SDK documentation for CreateNamedPipe for details about what else to pass.
Now, that returns you a handle (IntPtr in .NET). You can use that in a call to the constructor for FileStream:
IntPtr handle = CreateNamedPipe(@"\\.\pipe\Name123", ...);
Stream s = new FileStream(handle, FileAccess.ReadWrite); Now you've got a Stream to work with using managed code.

I'm trying to play a variety of sounds ( .wav files ) in a C# program and am having problems doing so. First off, I couldn't find any .NET native way to do so. Then I wanted to use the Win32 API call PlaySound, but since it's a lib and not a dll I can't do that. Finally, I wanted to use DirectX9, but after installing the SDK, if I put "using Microsoft.DirectX;" on the top of my form it says it doesn't exist.
Any clues?
Thanks,
