Are you sure, the "ComVisible" attribute are set on "true"? Default value is "false".
Maybe, this KB will help you: http://support.microsoft.com/?scid=kb%3Ben-us%3B249873&x=11&y=9

This is the code:
using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
using System.Runtime.InteropServices;
namespace register
{
public interface reg_inter
{
string procId();
}
[ComVisible(true)]
public class reg:reg_inter
{
public reg()
{
}
public string procId()
{
ManagementObjectSearcher search =
new ManagementObjectSearcher("select * from win32_processor");
foreach (ManagementObject wmi in search.Get())
{
PropertyDataCollection prC = wmi.Properties;
foreach (PropertyData pr in prC)
{
if (pr.Name == "ProcessorId")
{
return pr.Value.ToString();
}
}
}
return "0";
}
}
}
and this is assemblyinfo.cs:
.
.
.
// Setting ComVisible to false makes the types in this assembly not visible
// to COM components. If you need to access a type in this assembly from
// COM, set the ComVisible attribute to true on that type.
[assembly: ComVisible(true)]
// The following GUID is for the ID of the typelib if this project is exposed to COM
[assembly: Guid("3ea648c1-75cf-4d96-9978-d615378e027c")]
// Version information for an assembly consists of the following four values:
//
// Major Version
// Minor Version
// Build Number
// Revision
//
// You can specify all the values or you can default the Revision and Build Numbers
// by using the '*' as shown below:
[assembly: AssemblyVersion("1.0.0.0")]
[assembly: AssemblyFileVersion("1.0.0.0")]
Where am I wrong?

The error message (incorrectly copied as it is) suggests the connection in the source of the problem. Have you installed DB2 on your local machine?

How to create a simple alarm application in C#..

Take your problem, then break it in to smaller parts then implement the smaller parts. If the smaller parts are still too big then break it down further until you get to a point where you can create a "simple alarm application".
Now, we can help on specific elements of your application, but we cannot help with a whole application in a forum post.
Also, what do you mean by "a simple alarm"?
The following code could be perceived to be "a simple alarm":
Thread.Sleep(60000);
Console.WriteLine("Ding! Ding! Ding! Ding!");

Okay - then break the problem down into smaller parts.
Inputs: current time, alarm time
Outputs: At specified time "ring an alarm"
* The current time can be got from DateTime.Now
* The alarm time will have to be got from somewhere: Where? User input, config file, database, somewhere on the web??
* What do you mean by "ring an alarm"?

Hi all,
Does anyone know how to import online published Schema in to another schema in Biztalk 2006?
Thanks

Well, you could use a string builder to iterate over the second group of strings and build it into a single string. There's no automatic way to do it, you need to do it yourself.

I hate these drive by OP deletions.

Is there a component/addin for VS that provides incremental searching/filtering of components in ToolBox.
For example I'm designing a form and need to place a button control.
I would then type letters (b, u, t, t, ... ) inside search/filter box and all component classes matching entered characters would be filtered inside ToolBox or displayed within a DropDown window.
Thanks.

Hi, i've got a problem when using the localization possibilities of .NET.
I'm using sharpDevelop2 and i created two language files (en-US and fr-FR) to match the two languages. When i compile the soft, it work whell but the dll files created from the resx files are in two folders named fr-FR and en-US directly on the program root.
I'm searching for a way to create a global 'lang' folder in whitch i will put the languages folder.
I tried to put the resx files in a 'lang' folder created in my solution but the compilation faild because the resx files are dependent of the MainForm.cs and in this case it does not find this file.
Is there any way to do that in sharpdevelop ? If yes could you explain ?
or sould i use VS ?
I hope it's clear, thank for help.

AFAIK you cannot do what you want to (no matter which IDE you use) since the framework has a fix algorithm to look for those satellite assemblies.

OK so if i understand, if i want to localize my application for 100 languages, the compilation will create 100 directories directly in the program root !
I've never seen a program with such directory architecture !! So if i want to put my language dll files in an other directory, i have to do it by hands, could you give me a good solution to do that ?
thanks.

Maybe this (ResourceManager.CreateFileBasedResourceManager) can help you, but I'm not sure as I never needed to circumvent the standard procedure. If not, search the docs starting from the System.Resources namespace.

Odds are, the rich text box does not do that, and you'll need to write a custom control. Although, I suspect you could kludge it together.

I know there is no input box class in C# and we have to either import it from VB or write a custom input box.
But currently while I'm working with my program, it is an excel-like program with a grid table on the GUI, user can enter data into any cell on that (like an excel sheet), I come across a problem that whenever I call the input box to display, the currently selected cell will lose all its data.
I tried both the input box from VB and made a new form to display my custom input box, but the problem is still the same.
Can anyone help me identify why this happen ? I really have no idea why pop up a new form would make the currently selected cell in current form lose all the data, especially when the other cells remained unchanged.
Regards

Well there is really nothing wrong with a text box, but I don't need a text box here.
What I need is a pop up box to ask user input something and allow them to confirm/cancel with button, and that's why I need an Input box
