I think all dlls you refered are running at local machine, and two support remoting: web service and system.remoting, right? I'm not sure about it. Hmmm | :|

And also you can notice if you add a reference, vs.net will copy the file to your bin directory, does it means dll will be invoked local?

I'm amumu, and you?

How do i read one byte at a time from a remote file, i.e. a file from the web, then write each byte into a local file?

public static string RetrievePage(string url)
{
// Creates an HttpWebRequest with the specified URL.
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(url);

// Sends the HttpWebRequest and waits for the response.
HttpWebResponse myHttpWebResponse = (HttpWebResponse)myHttpWebRequest.GetResponse();

// Gets the stream associated with the response.
Stream receiveStream = myHttpWebResponse.GetResponseStream();
Encoding encode = System.Text.Encoding.GetEncoding("utf-8");

// Pipes the stream to a higher level stream reader with the required encoding format.
StreamReader readStream = new StreamReader( receiveStream, encode );

string retString = readStream.ReadToEnd();

myHttpWebResponse.Close();

return retString;
}

This function takes a URL as a string and the retrieves that URL. It shouldn't be difficult to modify this to make it work with binary (in fact I think it should work with no mods, but I can't be sure...).

Later,

printing Rich Text Format ???

Is there anyone out there who knows how to bring Rich Text to a place other than in the windows controls? I need to be able to print RTF (rich text format) to paper, and I have no earthly idea how. Does anyone have any ideas at all? Thanks in advance

You can view some sample Printing Documentation here

You can also view some sample code from the SDK that uses a RichTextBox and prints the text from it.

Hope that helps! Smile | :)

I am not so fortunate as to have VS.NET yet so I make do with SharpDevelop. However most of you have VS.NET and release your apps as VS.NET projects.
I am trying to get a reference to Shell32 in my SD project. The reference is originally in the FTP client project in the C# section of CP.
The code has this:

private Shell32.Shell m_Shell;

Of course a compile error has appeared saying "What the hell is Shell32?". By examining the XML of the VS.NET project I can see that it references Shell32 as a GUID:

<Reference
    Name = "Shell32"
    Guid = "{50A7E9B0-70EF-11D1-B75A-00A0C90564FE}"
    VersionMajor = "1"
    VersionMinor = "0"
    Lcid = "0"
    WrapperTool = "tlbimp"
/>

How can I import this into SharpDevelop?

The Internet, whats that? Is it a car?

I need to do a comparison of two dynamic numbers - say 150 and 225. How can I figure out the percentage difference (in this case, 50%) between these two numbers in ASP.Net?

Thanks.

I finally downloaded the .NET SDK to do some experimentation with it. Unfortunately an upgrade to Visual Studio.NET is out of the question at the moment, so I decided to look for a nicer way to build my experiments than .bats or makefiles. I'd heard a bit about ANT, a java based build tool, but I happened to spot another one... based on ANT... NANT. A .NET version of the ANT tool.

After getting it from http://nant.sourceforge.net I've had a bit of a play. Very nice! The build files are in XML, and seem a bit more straight forward than the old makefiles. They also claim that certain failures with makefiles are resolved by ANT/NANT. I've still got a lot of experimentation to go with it, but it looks very positive at the moment.

Anyway, thought I'd share this with you guys in case you hadn't heard of it before. Cheers.

You'll have to use COM Interop and load up the MS COM-Based HTML engine. I dont know of a native HTML parser for C# yet.

Hey all, I'm trying to make a project that builds a directory of files so that a user can burn them to CD. One of the requirements is that I have to have an autorun file that starts up an HTML file in IE. I don't know if this is the right place...but I thought I'd ask here first.

I'd try:

Put an Autorun.inf file in the root of your dir for CD.

in Autorun.inf put:

[autorun]
open = your_html.html

; the icon of the CD shown in the explorer
icon = the_cd.ico

/////
Should launch with your default browser.

ADSI Retrieving Domains

Ben Swann12-Jul-02 0:53

Ben Swann

12-Jul-02 0:53

I am trying to retrieve all the domains using ADSI. I don't know much about
ADSI and have been reading the docs on it with unavail.

I have currently used the code below to retrieve the users in the admin group
however, when the str variable is set to "WinNT://computer/Users,Group" it
gets to the loop stage and throws the exception: "specified cast is not valid"

To retrieve domains, I am guessing its similar to this code, however, I have
to change the Invoke method and filter etc.

Any help is greatly received

string str = "WinNT://computer/Administrators,Group";
DirectoryEntry ent = new DirectoryEntry(str);
IADsMembers mc = (IADsMembers)ent.Invoke("Members");
mc.Filter = new object [] {"user"};
foreach (IADsUser member in mc)
{
Console.WriteLine(member.ADsPath + ": " + member.Name);
}

IESourcing issues...

Ray Hayes11-Jul-02 12:51

11-Jul-02 12:51

In the .NET samples (and its online version at www.gotdotnet.com) there is an article about hosting a custom control within IE. I am damned if I can get it working (on two totally different machines/operating-systems/web-servers).

The steps I've done:
1) Take the DLL and HTML page and install it on my web-server
2) Create a virtual directory and allow execute access (not sure if I really need it)
3) Access the HTML through my IE6

All I get is a empty/dead object area.

After some (lots of) hunting, I found this link explaining that the little "broken image" icon is actually as a result of not having the correct access rights (apparently an exception is being raised).

http://www.mastercsharp.com/article.aspx?ArticleID=72&&TopicID=8

So, now.. I've increased the "trust" for my web-server (and placed it within the Trusted zone). Following their instructions, I need to "trust" the assembly. However, on the wizard (The "Which assembly do you want to trust" step) after entring the URL to the .NET DLL, I get an error complaining about it being unable to open the assembly.

If I browse to the directory and try to "Save Target" the DLL, I get a server error 500. The same happens if I try to download it using something like WGET. Any ideas?

I've tried this on the following setups with identical results:
w2k, IIS
nt4, PWS

Has anyone got this working? Please...

Regards,
Ray
