Re: Sending Fax Using RightFax.DLL in c#.net

30-Dec-04 7:28

RighFax is a third-party library/application and you need to read any developer documentation they have, like at http://www.captaris.com/customer_support/tech_docs/5609.html[^]. This forum is not about supporting third-party libraries, but questions specific to C#.

Your question is how to interop with it. For that, you can read about in Consuming Unmanaged DLL Functions[^] and Marshaling Data with Platform Invoke[^] in the .NET Framework SDK. If you have questions beyond what you should read you could ask here.

As far as what native APIs to P/Invoke, and what data structurs, constants, and interfaces to declare in C# is beyond the scope of this forum. You would only be able to determine that information by reading the developer documentation for RightFax or finding a developer community specific for RightFax, if such a community exists.

I want to develop a web server. When a user says from the browser http://localhost:8080 server must return a web page with text box and browser button and upload button. User can select the file and can click the button Upload. Let us say webserver.exe is present in c:\. When user clicks upload button this must be handled by the webserver and should upload the file to the same drive where the web server is running. I mean in C:\. In this case a POST method has to be handled. I am unable to handle the post method in my scenario. This will be regarding Content-Length,content-type processing.

Can any one help me in this regard by specifying sample code. I am already running out of submission date.

Developing a web server in C# probably wouldn't be the most efficient language to use, however if this is something you want to attempt, you should take a look at the System.Net[^] namespace, specifically the Socket[^] class.

Finding if a Pocket PC is attached to desktop via usb

If you want to host an ASP.NET web application without IIS, you can use the hosting interfaces. See the System.Web.Hosting[^] namespace in the .NET Framework SDK. Read ASP. NET Client-side Hosting with Cassini[^] in MSDN Magazine for an example of using the ApplicationHost class.

There's also several articles about building a web server (HTTP daemon) here on CodeProject, like Create your own Web Server using C#[^] by Imtiaz Alam. You can search for additional articles using the site search feature.

This will probably remain unanswered, but does anyone know of a method of finding out whether a pocket PC (ipaq) is attached to the desktop via the usb port? I've looked briefly at WMI using:

select * from Win32_USBHub

and System.Management.ObjectQuery, but couldn't find any clues. My other guess is that I use SendMessage with the ActiveSync exe, but this will be fidley.

Thanks

That's a rather negative way to start off a question. Fortunately some of us like research.

There are several ways documented in the ActiveSync APIs, from getting notified of connection to querying for a device ID, which I've coded below:

using System;
using System.Runtime.InteropServices;
 
class DetectDevice
{
  static void Main()
  {
    int id = CeGetDeviceId();
    if (id == 0)
      Console.WriteLine("Device not connected.");
    else if (id == -1)
      Console.WriteLine("Quest device connected.");
    else
      Console.WriteLine("Device ID: " + id);
  }
 
  [DllImport("ceutil.dll")]
  static extern int CeGetDeviceId();
}

Unfortunately I'm not able to test this, but it should work. This morning I decided to leave my iPAQ at home thinking I wouldn't need it, but figuring that if I didn't take it I'd probably need it. I guess I did.

Let me know if this works, though. There are a number of other ways, but this way seems to be the easiest.

The application is loaded into memory, along with dependent assemblies from dependent projects. To actually install the application and related content files you need to create a deployment project, then deploy into the emulator.

For more information about developing Smart Device Application and deployment projects for said projects, read Developing Smart Device Applications[^] in the MSDN Library.

If by "trace" you mean capture, then yes you can capture the [Tab] key being pressed. Handle the KeyDown event (or, in a derived control, override OnKeyDown, being sure to call at some point base.OnKeyDown) and check the KeyEventArgs.KeyCode for Keys.Tab.

You can extend controls to create your own, or create a UserControl derivative to contain multiple controls (what's called a container control). There's really not much you can't do.

If you're new to programming, I suggest browsing the relevent articles here on this site and checking out books about .NET at http://www.microsoft.com/mspress[^].

The following appears to work for me:

private double factorial(double f)
{
    double num = Math.Floor(f);
    if(num < 0)
    {
        return -1;
    }
    if(num == 0)
    {
        return 1;
    }
    else
    {
        return (num * factorial(num - 1));
    }
}

hi you must use arraylist;
do this:
you must define the multiplication yourself on the arraylist.
each elements of arraylist contains only one integer.
say
for( int i=1;i< 500;i++)
{
multiplay i in each elemnt of arrayList and add its more than 10 of element to next element such you do on paper.
}
you can calculate n! by this

try using decimal instead, if still too small, look for a BigNumber class, although that will slow things down. Why on earth do you wanna calculate such huge numbers?
