Thanx but I dont know how to extract body parts of e-mails. In the header the boundary can be xxx but in the body the boundaries can be yyy, zzz ... and xxx. How can I resolve this problem?

You should first see the RFCs for MIME, first: RFC 2045, RFC 2046, RFC 2048, and RFC 2049. You could also look in the Microsoft Exchange SDK documentation on MSDN.

MIME is delimited with boundaries in a hierarchical fashion based on the MIME multipart header. The hierarchy is the key. Each multipart will have separate boundary delimiters. For example, in a typical HTML mail, you will have something like the following:

Content-Type: multipart/related; boundary="=_A1"; type="multipart/alternative"
| --=_A1
+-Content-Type: multipart/alternativel; boundary="=_B2"
| | --=_B2
| +-Content-Type: text/plain
| | --=_B2
| +-Content-Type: text/html
| | --=_B2--
| --=_A1
+-Content-Type: image/gif
| --=_A1
+-Content-Type: image/jpeg
| --=_A1--

As you can see, each hierarchy has a different boundary delimiters.

RegularExpressions

Hi!

I'm trying out the regular expressions in C# (.NET); but I can't compile my source. The compiler complains about not recognizing "RegularExpressions". Fair enough, I thought. I just need a reference, right?

I have "using System.Text.RegularExpressions;" at the top of my file, of course. Problem is I can't add an assembly reference! When trying to I can't find the System.Text.RegularExpressions dll! I actually tried to seach my whole drive for it, and the only one found was in the compact framework and I can't add that one.

What am I doing wrong here?

PS.: Funny thing is, that the samples folder from the SDK (or maybe the IDE) contains some regular expressions samples with both source and .exe and I can run the .exe without problems (which uses the required dll at runtime)....

The name of the DLL (or assembly) is completely unrelated to which namespaces the types it implements are in.

The 'core' namespaces are spread between mscorlib.dll and System.dll. The most critical ones that are required for even the most basic bootstraping are in mscorlib.dll. This isn't just the System namespace, but Collections, IO, Reflection, Remoting, Serialization, Security, etc. The ones that other things don't depend on as much and hence may never need to be loaded are in System.dll. This includes CodeDom, ComponentModel, Net, RegularExpressions, etc.

Don't let the names of the other DLL's fool you either, for example System.Data.dll mostly implements types from the System.Data namespace, but it also implements some types that are in System.Xml and so forth.

Retrieving an icon from an embedded resx

I have created my own resx file and have embedded it into a dll. I want to create a dll containing all of my app's resources with a class that will retrieve these resources. The problem is, when I do GetObject() it returns a string not an object and I get an invalid cast error. Bellow is my code. The dlls name is Resx.dll and the resource file it contains is Resources.resx. Any ideas???

using System;
using System.Drawing;
using System.Reflection;

...

public class Resx
{
public Resx()
{
}

public static Icon Icon(string resx)
{
Assembly a = Assembly.GetExecutingAssembly();

System.Resources.ResourceManager resources = new
System.Resources.ResourceManager("Resx.Resources", a);

Object o = resources.GetObject(resx);
Console.WriteLine(o.GetType().ToString()); //outputs type String Confused | :confused:

return (Icon) o;
}
}

I am reading a graphic into an image (Image class) and displaying it on a form. Among other things, I am providing methods for moving the image around on the screen using the mouse. When the user clicks on the image I would like to shade the image (tint?) so that the user knows the image is selected. Similar to (or exactly like) like an icon changes color when the user selects one on the desktop. Any ideas about the best way to do that?

Converting ASCII text to a string

Hey Guys, bit of a C# newby, so if you could point me to a relevant article, or give a few tips would me much appreciated. I've got a file, which I load and decompress to ASCII text in a C++ dll (would have no idea how to do it in C#, unless there's a zip library for C#) and can import that into C# like:
byte * pBuffer=0;
int bytes;
if(DodgyImportFunction(sourceFile,&pBuffer,&bytes))
{
if(bytes>0)
{
//at this point have a pointer to a bytes byte*, but I need it as
//byte[] and C# won't be nice and let me cast it, so I can use it as
//ASCII text.
}
}
Any ideas of a better solution so I can get the decompressed data to be treated as ASCII text in C#?
Thanks, Brian.

Copy it into a string using Marshal.PtrToStringAnsi().

//declare your function like this:
private static extern bool DodgyImportFunction(
            string sourcefile, //don't know what datatype this was
            ref IntPtr buffer,
            ref int bytes
            );
 
IntPtr pBuffer=IntPtr.Zero;
int bytes;
 
if(DodgyImportFunction(sourceFile,ref pBuffer,ref bytes))
{ 
    if(bytes>0)
    {
        string str=Marshal.PtrToStringAnsi(pBuffer,bytes);
        //'str' should now be a managed string containing
        //the text from pBuffer
    }
}

Hi!

How does one retrive the IP-address of the remote host? I can only retrive the AddressFamily, and can´t find out how i retrive the address. Can I get the IPEndPoint for the remote host in some way??

Allow me to answer my own question. To retrive the IP-address og the remote host you can call RemoteEndPoint on the Socket connection, which you the call ToString() on to get IP and port number.

<br />
Socket con = Server.Accept();<br />
<br />
Console.WriteLine( con.RemoteEndPoint.ToString() );<br />

You can draw it on a form using the Graphics.DrawImage() method:

//assuming 'this' is the form to draw on,
//and 'bmp' is the Bitmap to draw
Graphics g = this.CreateGraphics();
g.DrawImage(bmp,new Point(0,0));

setup and deployment with MDB files

Anonymous31-Oct-03 5:14

31-Oct-03 5:14

Hello,

I have a project that uses a MDB file for it’s data. I am trying to make a setup and deployment project to install it the problem I am having is the path in the Crystal Report is seems to be hard coded from the wizard. I want it to use the path the exe is running when I try to set this in the IDE it throws a error. Is there a way to have the setup and deployment project set the path for this or is their a way I can do it?

Thanks for any help.

Re: setup and deployment with MDB files

Heath Stewart31-Oct-03 5:28

This isn't the responsibility of an install. The Crystal Report should be programmatically directed to the MDB by the program. If you're using the managed interfaces for Crystal Reports, you can use an OLE DB connection to the MDB file in your EXE's path (easy to get). Query something to generate a DataSet or something, then call ReportDocument.SetDataSource.

Besides, to set the path to the MDB in an install, you would have to write a custom action that actually changes the binary RPT file format, which isn't documented (to my knowledge). This is a proprietary format.

In any case, this is the responsibility of the program that displays the report. There are ways to programmatically set the report's data source at run-time and that is what should be done.

Re: setup and deployment with MDB files

31-Oct-03 6:31

Thanks but I must be missing somthing. I am trying to learn crystal and have a hard time. It seems to me in order to use reportdocument, I have to use reportdocument.load and I need to provide this a path and that will put me with the problem I started with. I have a report file already made.
